作为非谓语形式，分词可用作形容词和副词，在句子中充当定语、表语、补语和状语。但它仍保持动词的一般特征，可以有自己的宾语和状语。分词和自己的宾语、状语构成分词短语。

现在分词有主动语态和被动语态(being + 过去分词)。

过去分词只有一般式，表示在谓语动词所表示的动作之前发生的动作。过去分词（及物动词）本身可以表示被动的含义，因而没有别的被动形式。

1．作定语。

作定语的分词通常放在被修饰的名词________________。

高三英语复习课件 篇3

SeniorⅢ Unit4 Green World Integrating Skills

一、 教学思路：

1 . 高考阅读理解的特点是所选材料题材多样化，记叙文、说明文、议论文、应用文等特色鲜明，内容涉及科普、社会、文化、政治、经济、历史等各个方面，文章阅读量大。主要考查考生综合运用所学知识获取信息、整理信息、理解信息以及处理信息的能力。测试的主要要求是：

①．掌握所读材料的主旨和大意，以及用以说明主旨和大意的事实和细节。

②. 既能理解具体的事实，也能理解抽象的概念。

③．既能理解字面的意思，也能理解深层的含义，包括作者的态度、意图等。

④．既能理解某句，某段的含义，也能理解全篇的逻辑关系，并据此进行推理和判断。

⑤．既能根据所提供的信息去理解，也能结合中学生应有的常识去理解。

根据这五项要求，我们可将阅读理解题归纳为以下几种题型：细节理解题，词句理解题，主题、主旨题，猜测词义题，推理判断题。

2． 高考的要求就是我们平时课堂教学训练的方向。高中英语课文内容包罗万象、题材广泛、体裁各样、语言知识丰富。除了要让学生掌握英语基础知识外，我们更可以利用课文的教学，精心设计问题，按照高考的要求有针对性地对学生进行问题解答训练，提高学生的阅读速度，培养学生的阅读理解能力。

二、教材分析：

本课是第四单元综合技能部分的课文，介绍了达尔文和其他科学家关于物种的研究和他们的成果。内容涉及到遗传学和基因学的知识，文章有一定难度。是本单元主题绿色世界的一个延伸，又为本单元紧接的写作训练作铺垫。

三、 教学法分析：

1、 问题教学法。精心设计问题，以问题为主线，在提出问题和解决问题过程中，培养学生阅读理解能力。设疑与提问是英语教学课堂调控的常规武器。它是促进师生之间信息交流反馈，推动教学流程迅速向前拓展的重要契机。

2、 “自上而下的模式”。 这是哥德曼（Goodman）提出的阅读理论模式。按这个模式，阅读者在阅读过程中不是逐字、逐句地去理解，而是结合自己的预测，在文章中找出有关的信息，来验证自己的预测。由于强调整体篇章理解，在阅读时采取跳跃式搜索、猜测等方法，所以有利于培养学生快速阅读理解能力。

四、 学生分析：

两个班学生基础有限，学习英语有兴趣但没功底。成绩差距较大。尤其对文章缺乏整体感知能力，对深层次问题无从下手，信息的获取和分析能力都较弱。

五、 教学目标及重难点：

由于本课教学以发展学生解决问题能力为主，不设知识目标与情感目标。能力目标亦即重难点：

1、 培养学生快速获取信息解决表层次问题的能力；

2、 培养学生深层思考，培养信息重组、推理分析判断能力。

七、 教学步骤：

1． Lead in: Show two pictures on the blackboard:

2. What are differences between them? Why?

Maybe we can find the answer to this question in our text.

2. Fast reading: Open the book, read through the text. Find out:

How many scientist are mentioned in the text?

S：There are three. They are:

Charles Darwin Gregor Mendel Gote Turesson

T：So how many parts can we divide the text? (划分段落，整体感知)

T: Could you find the main idea of each paragraph?

学生做完这个步骤后，我总结并用幻灯打出：

Part I (Pa1-3): Darwin and his research.

Part II (Pa4-5): Mendel and his experiment.

Part III (Pa6): Turesson and his study

Part IV (Pa7): the importance and significance of the research of the three

3. Careful reading: (1) Show a slide of a table, ask the student to read the passage again, fill in the following:

Scientists Research/experiment Result

(用图表的形式处理文章信息，既避免问题提出的形式重复，又方便学生整体快速把握文章的重点段落)

(2) (完成以上整体表层次训练后，通过幻灯片打出以下问题，再细部理解文章)

Finish the following exercises:

1. What led to his writing of the famous book On the Origin of species?

A. The study of physics, chemistry, and botany.

B. What he had observed on the voyage.

C. His expedition on the Beagle to the Galapagos.

2. Why did the wildlife of the Galapagos Isles deserve special attention?

3. What does “these” in “of these” in Para 2 mean?

4. “those” in Para 2 Line 4 refers to ________

A. the different islands B. the life forms C. differences D. the species

5. What was the purpose of Mendel’s experiments?

A. His purpose was based on his love nature.

B. His purpose was to support the ideas concerning the influence of

environment upon plants.

7．What was Darwin’s new theory according to the text?

(以上问题有深有浅，既有符合高考的细节理解题(如第1题)，词句理解题(如第3、4题)，推理判断题(如第7题)，设计时更因答案的不唯一性(如第1题BC均正确)，增加了题目的灵活性和难度。在解答过程中特别强调：

第1题：选项在文章中都有出现，但未必就是答案。题目不难，容易上当。

第3题：培养学生联系上下文准确把握词句意义，这道题目难度不大，但出奇的是学生正确率并不高。

第4题：这与第3道题是一样的，但难度较大。这两道题的题型在高考中经常出现。

第7题：这道题很难。考查学生对文章事实的延伸理解，训练学生根据文章事实作出推理判断的能力。是一道深层次理解推理判断题。)

(3) Answer the last question:

What do you think is the relationship between the title “Wildlife and Garden

Roses” and the text?

（这个问题非常难！也是整节课的精华部分，解决分析这个问题我花了十多分钟时间。问标题和文章的关系并不新鲜，关键是这个标题用得非常好，借此我分析了高考中常考的一类题目：给文章找标题。完成这个问题既是对整篇文章的概括理解，又是对高考常考题型解题技巧的一次传授。）

Wildlife shows the influence of environment while Garden of Roses shows the

science of genetics.

八、 Homework:

1. Read the text.

2. Learn the language points by yourselves

1、 高中英语课文应该怎么教？又要教什么？这一直让我思考。我想很多英语老师对课文当中的语言知识是绝对不会漏的，但是不是通过课文的教学培养和训练学生的阅读技巧和阅读能力了呢？也许因为时间，也许因为方法，可能落实不太好。尤其在高三，课文没有出现新的语法点，怎样通过课文的教学达到这一目的，以利学生高考，更值得我们思考。

2、提问是一门艺术，也是一种教学方法。苏联教育界倡导的一种教学方法就叫问题教学法，已成为有世界影响的教学方法之一。问题是思维的向导，合适的课堂提问，往往能把学生带入一个奇妙的问题世界，使学生积极思考问题，寻求解决问题的途径和答案，从而培养学生分析问题和解决问题的能力。布鲁斯乔伊斯说过：“教会学生独立思考，我们就给了他们自我教育的能力。” 课文教学未必要设很多的问题，但要典型；其次问题分析要透彻，分析一个问题就要教会学生一种技巧或是让学生有一次能力的锻炼。问题设计是否巧妙，问题分析是否精当，就是判断这种课好坏的依据。

我们结合《英语周报》高三广州专版第30,31期的专题复习内容研以及配套的例题分析(见《英语周报》),针对高考阅读理解的四种主要题型,给学生做解题策略指导和技巧总结.

策略指导：先浏览一遍题目，把题目的要求储存在大脑中，带着疑问去快速阅读，然后找出与题目相关的信息词句加以理解分析，去伪存真。此种办法能有效地避免做细节理解题时的失误。

【技巧总结】准确捕捉信息，注意对信息进行综合分析，分清主次、真伪，避免受信息的干扰，陷入高考题所设下的“陷阱”，误选干扰项，因为某些干扰选项在文章中也能找到“依据”，具有很强的迷惑性。

策略指导：深层含义通常是隐藏在文字背后的延伸之意，弦外之音，如作者的意图、倾向、语气，人物的性格、心理、情感，故事的结局，事情的因果关系等。因此大家需调动自己的逻辑思维能力，透过字里行间，去严密推理，合理想象。

【技巧总结】隐含信息并非“空穴来风”， 而是“有源之水”，即隐含信息也是以文章的语言为载体。大家应准确捕捉信息，调动智力因素，严密推理，合理想象，忌“凭空想象 ”或“断章取义”。在阅读理解中结合自己的常识进行判断是必要的，但决不能以常识取代信息分析。推理判断既要严密，又要灵活。

策略指导：首先从词汇所处的语境进行分析，注意上下文之间的关系，如：如果出现that is, that is to say或破折号等，我们可以断定，后面的内容是对前面内容的解释；如果出现转折词but, however, yet以及表示相反结果的on the contrary, on the other hand等，我们可以从所给内容相反的意义去考虑。

【技巧总结】高考语意判断题很多都是考查旧词新义的理解。因此大家需把词汇或短句的字面意义与语境和上下文结合起来，选择最切合文章内容，最符合上下文逻辑的意义，切忌望文生义。

策略指导： 读完一篇短文后应有意识地回味一下文章的大致内容，理一理文章的脉络，体会一下段与段之间的内在联系，这样做文章的中心一般都能概括出来, 涉及文章主旨大意方面的题目自然会在头脑中由模糊变清晰。

【技巧总结】我们在归纳文章主题时，一定要注意选项的内涵和外延必须能恰如其分地概括文章的主题，既不能范围过大，也不能把某一细节或侧面误当作主题。阅读时我们还应注意捕捉文章出现频率较高的中心词汇以及文章和段落的主题句。在选择文章题目时，还应注意语言方面的特点：文章题目往往具有凝练、醒目的特点。

猜测词义是从特定的角度考查考生的阅读理解能力和处理生词的能力。猜测词义包括对词、词组和句意的理解，是高考英语试题阅读理解中的一类必考题。猜测词义题常见的解题方法：

任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析而推测词义，是阅读过程中的一大关键，也是高考的热点。

如：If he thinks he can invite me out, he is all wet. I don’t like to be with him.

A. drunk B. sweating C. happy D. mistaken

分析：根据I don’t like to be with him我们感受到说话人的语气。我不愿意跟他在一起，那么，他要邀请我出去是不可能的 他就大错特错了。因此答案D。

阅读文章中的有些生词尤其是新闻报导及科普类文章中的生词，往往在其后有对该词进行解释说明性的短语或句子，如to be, that is , mean, stand for, namely, to refer to, to mean ,in other words等，有时也以同位语、定语从句的形式出现，或用破折号、括号来表示。

如：Some ships carried cargo such as coal, oil and military supplies(军用物资),while others carried only passengers.

分析：such as后所列举物品均为“货物”，由此推断cargo的意思相同，和后面的passengers形成对比。

有的文章作者为了增强表达效果，会用一对反义词揭示事物的不同点，形成鲜明的对比，这时只要把握其中的一词，就不难推出另一词的含义，这种句子多见unlike, although, but, yet, while, on the contrary, on the other hand, for one thing, for another, instead of, rather than等信息词。如：One idea about business is that it can be treated as a game of perfect information. Quite the reverse, business polite, life itself is games which we must normally play with very imperfect information.

A. Quite right. B. Time enough. C. Most unlike. D. Just the opposite.

分析：由前句中perfect information到后面imperfect information这一组对比关系的词，我们可以推断应为“对比、相反”的意思。

常见的引出同义词的标志性词语有or, like, similarly等。如：

Millions of animals die each year on Us roads, the Highway administration reports. In fact, only about 80 ocelots, an endangered wild cat exist in the US today. The main reason? Roadkill.

分析：从后面的同位语an endangered wild cat可知“ocelot”是一种野生猫

某些冷僻的词汇后面会举一个例子，使词汇具体易懂。等连接性词语往往用来举例说明前面较难理解的名词。

如：You can take any of the periodicals: The World of English, Foreign Language Teaching in School, or English Learning.

分析：通过后面的例子：《英语世界》、《中小学外语教学》、《英语学习》，可知periodicals为“期刊杂志”

阅读中常会遇到一些由所熟悉的单词派生或合成的新词，可利用构词法知识来推测其意思。

如：Exhibition officials said that a person bitten by one of these snakes would need at least 80ml of an anti-poison medicine to be saved.

分析：anti-poison 是由poison加前缀anti-构成的，anti-意思是“反对、排斥、抵抗”，由此可猜出anti-poison是“解毒、抗毒”的意思。

5. 结构复杂的长句子出现在阅读理解中往往造成大家心理上的紧张，有时读了好几遍还不知道句子的意思，白白浪费了时间,如何对待阅读理解中的长句子?

策略指导：阅读理解中的结构复杂的句子一般分为两大类：第一类是由复合句或并列句构成的长复杂句子；第二类是省略句。对于第一类句子，大家应抓其主干成分，理解其主体意思，其他的成分都是对主体意思的修饰和补充。对于第二类句子，大家应通过上下文找出省略成分，把句子补充完整。

【技巧总结】结构复杂的句子往往出现在说明文或议论文中，这是造成考生心理紧张的主要原因。大家应冷静下来，结合文章所说明或议论的中心话题，抓住主干，层层理解。

主要考察学生的速读能力，即在有限的时间内理解、总结信息并且能快速找到相关的信息的能力。学生要学会寻读（scan），抓关键信息，然后进行匹配。

Step 3 Homework and consolidation exercises

1. 《英语周报》高三广州专版第30,31期的专题复习内容。

2. 《英语周报》高三广州专版第33-34期的年高考英语模拟试题（一 ）--（十二）一共12套。

3. 和2007年全国各地的英语高考试题中的阅读理解。

阅读理解旨在考查考生理解总体和特定信息的能力。

任何一篇文章都有一个主旨要义。有时从文章的第一个段落甚至第一个句子即可以得出文章的主旨要义。从这个段落或句子，读者可以知道文章描述的是谁或什么即文章的主题，也会了解作者希望读者了解主题方面的哪些内容。有时，文章的主旨要义则需要从文章的字里行间进行推断。这类试题主要考查考生的略读文章、领会大意的能力，有时候它

对考生的归纳、概括能力有一定的要求。

一篇文章的主题和中心确定之后，还需要有大量的细节信息支持。这些细节对于理解全文的内容至关重要，同时也是归纳和概括文章中心思想的基础，因而不容忽视。

正确理解文章中单词或短语的含义是理解文章的第一步，也是理解文章的基础。不懂得单词的含义根本就谈不上理解文章。但是，有时候英语单词的含义并非等同于词典上标注的汉语意思，其含义随不同的语境会有所不同。根据上下文正确理解灵活多变的词义，

才算是真正初步具备了一定的阅读理解能力。

在实际阅读活动中，有时候需要根据文章提供的线索和事实，进行逻辑推理，推测作

者未提到的事实或某事情发生的可能性。

英语文章讲究主题段和主题句。主题段通常在文章的开头，主题句可能在某一段的开头、中间或结尾，作用是交代该段的中心思想，再由全段展开或讨论这个意思。段与段之间通常有词语连接，承上启下，使文章行文连贯。如果希望准确、深刻地理解一篇文章，必须对文章的结构有所了解，把握住全文的文脉，即句与句、段与段之间的逻辑关系。对

这种能力的考查一般反映在文章的中心思想、文中某段的大意或指代关系的题目中。

每篇文章都有一个特定的写作目的，或是向读者传递某个信息，或是愉悦读者，或是讲授某个道理。而这些信息通常不是明确表达出来，而是隐含在文章之中。因此，这类问

题要求考生在理解文章总体的基础之上，去领会作者的眼外之意。

下面结合2007年广东高考阅读理解试题，具体分析对这些能力的考查：

A

How should one invest a sum of money in these days of inflation (通货膨胀)? Left in a bank it will hardly keep its value, however high the interest rate. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your saving and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.

I sometimes wonder what a being from another planet might report back about our way of life. “The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound, it has a face with twelve black marks and two hands. Men can do nothing without it's permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves. ” Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time of day according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout the time. So it seems that the first clocks were human beings.

However, men quickly found more convenient and reliable ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hourglasses, and invented water-clocks. Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.

Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by time, why not invest in an antique clock and perhaps make a future profit?

41. According to the passage, collecting antique clocks______.

A. can hardly keep the value of your savings

C. Observing shadows cast by the sun.

D. Keeping slaves busy day and night.

44. The underlined phrase “stately homes”in paragraph 4 means________.

B. houses in very good condition

C. grand houses open to the public

D. houses where statesmen meet regularly

45. The purpose of the passage is_______.

A. to introduce the culture of antique clocks

B. to offer some advice on collecting antique clocks

C. to compare different ways to make a future profit

D. to explain convenient and reliable ways of telling time

[导读] 这是一篇叙议结合的散文。人们在通货膨胀的今天应该怎样投资一笔钱呢？存在银行里，这笔钱几乎不能够保值，无论存款利息多么高。只有勇敢的人或是富有者才敢于在股票市场买卖。今天保护你的储蓄甚至增加你的财富最好方法之一似乎是购买过去遗传下来的漂亮的物品。因此，作者顺理成章地提出一些关于收藏古董闹钟的忠告，奉劝人

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.

Here's an example to show how honorable actions create happiness.

Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.

Then, what is it to do with our sense of happiness?

In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.

There is a beautiful positive cycle that is created by living a life of honorable actions.

Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

46. According to the passage, the positive action in the example contributes to our .

47. The author thinks that keeping silent about the uncharged item is equal to .

48. The phrase “bringing the error to the clerk's attention” (in para. 5) means .

A. telling the truth to the clerk

C. asking the clerk to be more attentive

D. reminding the clerk of the charged item

49. How will we feel if we let the clerk know her mistake?

A. We'll be very excited.

B. We'll feel unfortunate.

C. We'll have a sense of honor.

D. We'll feel sorry for the clerk.

50. Which of the following can be the best title of this passage?

D. Happiness through Honorable Actions

[导读] 这是一篇说理、规劝性的议论文。本文的中心是：作者提倡通过高尚的行为获得幸福，规劝人们多行善事获得幸福，以形成一种美丽的积极的循环。高尚的思想行为可以使你的生活具有一种和平感、幸福感、善良感和自尊感。过高尚行为的生活可以创造美丽的积极的循环。高尚的思想导致高尚的行为。高尚的行为致使我们幸福的生存。当我们幸福的时候，我们容易产生高尚的思想和行为。虽然积极的循环难以开启，但是，一旦开启，就容易继续下去。坚持不断地做善事会给我们到来平静的心理，这样做对我们的幸福

自己就是小偷。

48. A。句子意思猜测题。第5段分两层意思。第1-5句是第一层意思：在第一个案例中，我们不告诉那个职员，有几件事情会发生。在内心深处我们会知道我们自己就是小偷。在这个过程中，我们的心理会失去平静，也失去自尊。我们也会证明我们不可以信赖，因为我们通过告诉家里的人和朋友的方式来忠告我们的耻辱。第5段第6-8句是第二层意思：比较而言，把这个错误引起这个职员的注意导致几件事情发生。职员立刻知道我们是高尚的（honorable）。我们一离开商店，就感觉到是高尚的，并且我们的自尊在增加。通过对比这两层意思，可以判断bringing the error to the clerk's attention意思是“实话告诉这个职

员”。

49. C。细节事实理解题。第5段第7-8句：Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. 职员立刻知道我们是高尚的（honorable）。我们一离开商店，就感觉到是高尚的，并且我们的自

Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.

Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.

For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

51. According to paragraph I, many people don't seek care because .

C. they can remain unaffected for long

D. there are too many people suffering from the disease

52. People suffering from malaria .

A. have to kill female mosquitoes

B. have ability to defend parasites

C. have their red blood cells infected

D. have sudden fever, followed by chills

53. Which of the following may be the reason for the wide spread of the disease?

A. Its resistance to global warming.

B. Its ability to pass on the virus frequently.

C. Its outbreaks in cities with large populations.

D. Its ability to defend itself and resist new drugs.

54. It can be inferred from the passage that .

A. no drugs have been found to treat the disease

B. the alternative treatment is not easily available to most people

C. malaria has developed its ability to resist parasites

D. nobody knows what will be the drug to treat the disease

55. Which of the following questions has NOT been discussed in the passage?

A. How can we know one is suffering from malaria?

B. How many people are killed by malaria each year?

C. Why are there so many people suffering from malaria?

D. What has been done to keep people unaffected for long?

[导读] 这是一篇介绍医学科普常识的说明文。本文主要介绍疟疾病的起因、传播、危害与治疗。疟疾（Malaria）是世界上传播最广泛的寄生虫引起的病，每年都要使三百万人致命--几乎全是5岁以下的孩子，并且是贫穷的非洲人。疟疾病本身有很多基因，对于各种新药物具有抵抗性，所以目前还没有找到根治疟疾病的最佳治疗方法和药物。

51. A。细节事实理解题。见第1段第2-3句：... because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. (多年来，有5亿多病例由这种病引起的，虽然确切的数字难以估计，) 因为许多人不去寻求（或不可能）医疗护理。这种情况对于一个年收入不到200美元的家庭并非不同寻常，因为要治疗疟疾病，

就花去年收入的四分之一，并且他们时常所得到的不再有效。

52. C。细节事实理解题。见第2段第3句：Malaria parasites live by eating the red blood cells they infect (感染) .疟疾寄生虫依靠吃他们感染的红血球生存。这说明疟疾病患者的红

血球受到感染。

53. D。细节事实理解题。这种疾病之所以广泛传播是因为它有一种自我防御和抵抗新药物的能力。见第2段倒数第3句：Malaria has five thousand genes, and its ability to change

rapidly to defend itself and resist new drugs has made it nearly impossible to control.。

54. B。推理判断题。根据第3段倒数第2句：Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. 一些成功的可供选择的化学药品在阻止疟疾的这种抵抗力方面已经出现效用，但是这些可供选

择的化学药品非常短缺，并且昂贵，因此大多数人不容易得到可供选择的治疗。

55. D。细节事实理解题。A项见第2段第1句：Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches；B项见第1段第1句：... kills as many as three million people every year almost all of whom are under five, very poor, and African.；C项见第2段第3句：Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.；又见第1段第2

句：... because many people don't (or can't) seek care.；D项没有提到。

高三英语复习课件 篇6

1.利用课文的词、句复习，训练学生的组句能力。从词和句入手，将每个单元课文的词和句与基础写作结合起来，是培养和提高学生的英语能力的有效途径。这不仅能帮助提高学生记忆和灵活应用词汇的能力，而且还有助于训练学生语句表达的正确性。

(1)归纳词汇和句型，帮助学生建立对词、句使用的感性认识。写作是一种语言的输出形式，只有大量的语言输入，语言输出才有可能;只有积累了一定的感受和大量的语言素材，写作才有可能进行。为了帮助学生记忆课文中的单词和短语，达到积累语言素材，掌握基本语法知识与语句结构的目的，教师可以从训练学生归纳每个单元课文中出现的重要词汇、短语和常用句型入手，使学生对句型结构的认识更加清楚，并对词、句的使用语境形成感性的认识。

(2)操练词汇和句型，训练学生的记忆和使用词、句的能力。为了使学生掌握和应用课文中所学词汇和句型，教师应为学生创设多层次的练习活动，拓宽写作的.训练途径。教师可采用将学生从课文中归纳的词汇、句型进行词类转换、习惯用法、句型转换、完型填空、写短文等形式的训练，帮助提高学生的记忆和使用词、句的能力。

二、借鉴课文词、句进行仿写。

通过提供情景让学生模仿造句，不仅可以降低写作难度，而且可以增加学生写作的兴趣、自信和成就感，使学生的遣词造句的能力在实践中得到提升。

三、借鉴课文句型，训练写作多种表达与技巧，拓展学生思维。

教师在教学实践中会发现，学生在基础写作中往往出现句式雷同、语句呆板、行文单一等现象，缺乏用5个句子有效表达和传输信息的能力。因此，教师就有必要继续进一步加强句子多样化表达、句子转换替代、句子合并等训练，教会学生使用不同的短语、句型结构表达同一的意义;同时，还让学生明白写作的逻辑原则:一个句子表达的信息量越多，而且使用的句子越精练、清楚，那么句意表达和传输信息就越有效。

四、利用课文体裁，训练学生谋篇布局的能力。

教师会发现高三学生在写作中存在的另一个问题是层次不清、结构散乱以及逻辑性不强，这是因为学生缺乏谋篇布局的能力。针对这方面问题，教师可以在教学中利用课文的体裁进行文章结构方面的训练以及进行句子、段落间的连接训练。

高三英语复习课件 篇7

英语阅读中，有时作者并未把意图说出来，而是要求阅读者根据字面意思，通过语篇逻辑关系，研究细节的暗示，推敲作者的态度，理解文章的寓义，这就是判断推理题。判断推理题在阅读测试中属于难题。因此，考生应在理解全文的基础上，从文章本身所提供的信息出发，运用逻辑思维，哲学原理，并借助一定的常识进行分析，推理，判断。

推理题经常使用的提问方式有：

It can be inferred/ concluded that___________.

Which of the following conclusions can we draw according to the passage?

In which of the following publication would this passage most likely be printed?

The passage implies, but doesn't directly state that___________.

The writer suggests that___________.

What's the author's attitude toward___________?

The writer probably feels that___________.

The author uses the examples of... to show that___________.

判断推理是一种创造性的思维活动，但它并非无章可循。

推理判断题要在阅读理解整体语篇的基础上，掌握文章的真正内涵。①要吃透文章的字面意思，从字里行间捕捉有用的提示和线索，这是推理的前提和基础；②要对文字的表面信息进行挖掘加工，由表入里，由浅入深，从具体到抽象，从特殊到一般，通过分析、综合、判断等，进行深层处理，符合逻辑地推理。不能就是论事，断章取义，以偏概全。③要忠实于原文，以文章提供的事实和线索为依据。立足已知，推断未知。立足现在，预测未来。不能主观臆想，凭空想象，随意揣测，更不能以自己的观点代替作者的观点；④要把握句、段之间的逻辑关系，了解语篇的结构。要体会文章的基调，揣摸作者的态度，摸准逻辑发展的方向，悟出作者的弦外之音。

要求考生根据语篇关系，推断具体细节，如时间、地点、人物关系、人物身份、事件等。一般可根据短文提供的信息，或者借助生活常识进行推理判断。

A visitor visits an island where two tribes live. One tribe always tells the truth and the other always lies. The truth瞭ellers live on the western side of the island, and those who lie live on the eastern side. The visitor wants to determine whether the native beside him is a truth瞭eller or not by asking only one question. He asks the native,“Go and ask the native in the distance which side of the island he lives on.” When the messenger returns, he says, “He said he lives on the western side of the island.”

Is the messenger a truth瞭eller or not? How can the visitor be sure?

1. According to the messenger's answer, the visitor can conclude that_______________

A. The messenger lives on the western side of the island because he tells the truth.

B. the messenger lives on the eastern side of the island because his answer may be a lie.

C. it's hard to determine whether the messenger is a truth teller or not.

D. the messenger probably lives in the western side of the island because his answer may be true.

2. The native in the distance says he lives on the western side of the island. According to his answer, which conclusion of the following is wrong?

A. He may live on the eastern side of the island.

B. He may live on the western side of the island.

C. He may be telling the truth.

D. He can't be telling the truth.

【解析】 第1题是推测有关信使（近处的当地人）的情况的。我们知道，讲真话的部落住在岛的西部，撒谎的部落住在岛的东部。这个信使去问远方的当地人住在岛的哪一边（东部还是西部）。远方的当地人只能有两种情况，要么住在岛的西部，要么住在岛的东部。如果他住在岛的西部，他就是一个讲真话的人，他就会如实回答他住在西部。如果他住在岛的东部，他就是一个撒谎的人。他本来住在东部，但在回答时，必须要说谎，他只能回答他住在西部。所以远方的当地人不管是住在东部还是西部，他的回答只有一个：“我住在西部”。如果信使告诉参观者远方的当地人住在西部，信使无疑是说了真话，那么信使一定是住在岛的西部。反之，如果信使告诉参观者远方的当地人住在东部，那么信使就说了假话，信使肯定住在东部。故此题答案是A。

第2题是推测远方的当地人的情况的。从短文提供的信息来看，我们无法判定远方的当地是住在岛的东部还是岛的西部，两种情况都是可能存在的。此题要注意情态动词的语气。A.“他可能住在岛的西部”;B.“他可能住在岛的东部”;C.“他可能讲了真话”。上述A、B、C三种情况都是可能的。D.“他不可能讲真话”，语气太绝对。推测错误。故答案为D。

要求考生根据已知结果推测导致结果的可能原因。考生要准确掌握文章的内涵，理解文章的真正含义。

When the young waitress near my house started saying hello to me every day, I was very happy. She was at least fifteen years younger than I. One day she signedme to come near. When I walked over, she asked,“Are you single?“ “Why, yes.” I answered, smiling at her happily.

“So is my mother.“ she said, “Would you like to meet her?”

1. The writer talked about the waitress' age because he thought___________.

A. she was young B. it a pleasure to make friends with her

C. she was beautiful D. it strange for her to fall in love withhim

2. The waitress said hello to the writer every day because___________.

A. she lived near his house B. he often went to visit her mother

C. she wanted to be friendly with him D. she loved him very much

【解析】 这是两道推测原因的题目。女服务员每天向作者示好，作者产生误解，以为女孩对他有意。考虑到他们年龄相差悬殊，作者认为女孩爱上他有点奇怪。故第1题答案是D。女孩问作者是否单身，并提到她母亲也是单身，并邀请他与她母亲见面，可见，女孩每天向他问好，目的是想取得他的好感，进而搓和他和她母亲。第2题答案是C。

The entertainment profession or “show business“ attracts many young people. Unfortunately, only very few can hope to become famous and successful. Talent is not enough, because show business is as competitive as any other business .Without a good manager ,a performer can never hope to succeed .Fashion is important in this business, too. The best tailor in the world will never be a success if he makes old瞗ashioned clothes. In exactly the same way, a performer must changehis “act” in order to follow the taste of the moment. This is true for actors, dancers and comedians ,but perhaps most of all singers.

“Pop“ stands for “popular” and a pop singer has to work very hard to become popular .He must either give the public what they already want, or he must find a new way of singing that will attract their attention. Even when he has succeeded, and his records are sold everywhere, he can not relax. Then he must work harder than ever because there are always younger singers trying to become famous and to steal some of the popularity. The life of a successful pop singer is not at all easy. He can only relax when he is alone, because everything he does is watched and reported in the special newspaper written for the “fans“.The fans are the most important people in the world for the singers. They buy his records, they go to his concerts and they make him rich and famous. But they can be very annoying, too. Sometimes their enthusiasm get so hysterical that they do anything to get a“souvenir”（纪念品）. They steal handkerchiefs, they tear off buttons, and they even cut off pieces of the unfortunate singer's hair. Many singers have been forced to hide. A pop singer has to spend a lot of money on clothes, because he must always look smart or at any rate different. He must have a luxurious car. And - most important - he must always keep smiling for the benefit of his public .

1. Why must a pop singer have a good manager?___________.

A. To protect him from his fans B. To look after his business interests

C. To help him to change his “act“ D .So that he can relax

2. Why must a pop singer work even harder when he has become famous?___________

A. Because he wants to attract the attention of the public

B. Because he wants to sell more records

C. Because he wants to become popular

D. Because he wants to stay popular

【解析】 1. 答案为B。因果推断题。根据Talent is not enough, because show business is as competitive as any other business. Without a good manager, a performer can never hope to succeed .我们可以知道，正因为这个行业竞争激烈，所以表演者需要一个好的经纪人。帮助演员策划和安排商业表演活动，协助他的演艺事业的发展。故B项正确。

2. 答案为D。因果推断题。Then he must work harder than ever because there are always younger singers trying to become famous and to steal some of the popularity. 一个成名演员要更加努力地工作，直接原因文中已有论述，即，表演行业是个竞争十分激烈的行业，新人不断涌现，对成名演员造成很大的压力。那么间接原因是什么？通过前面的分析我们可以推断出成名演员更加买力地工作，是因为他要保持他的名气，延长他的艺术生命。

Once Napoleon stayed in a small inn. The next morning, he went to thank the ﹊nnkeeper.ァ癥ou, have served me well, innkeeper, ” said Napoleon. “I wish to reward you. Tell me what you want.“

“Sir, we want nothing, ” said the innkeeper.“But will you tell us something?“ァ癢hat is it?” Napoleon asked.

“We have heard a story.“ said the innkeeper, “that once during the war, a small village was taken by the Russians. You happened to be in the village. You hid while they looked for you. Will you tell us how you felt when they were looking for you?” Napoleon looked very angry. He called in two of his soldiers. Then he pointed to the door. The soldiers took the innkeeper and his wife out into the yard.

At the end of the yard was a wall. The innkeeper and his wife were led to the wall. The soldiers tied the hands of the innkeeper and his wife. Napoleon watched, saying nothing.

“Please, sir.“ begged the innkeeper, “Don't kill us! we meant nothing!” The soldiers moved back. The innkeeper saw them raising their guns. Then Napoleon called: “Ready! Aim!“ The wife screamed. “Stop!” said Napoleon. He went to the innkeeper, “Now, you know the answer to the question you asked me just now, don't you?“

1. Why did the innkeeper ask Napoleon to tell him how Napoleon felt when he was being looked for?

A. He wanted to know the difference between a general and an ordinary people.

B. He looked down upon Napoleon, for he thought a great man shouldn't be defeated.

C. He showed his玸ympathy(同情) to Napoleon in time of danger.

D. He was interested in other's failure, especially Napoleon's.

2. Why did Napoleon ordered his men to tie the couple?

A. Because he wanted to teach the innkeeper a good lesson for bothering him.

B. Because he wanted to kill the couple to get rid of his anger.

C. Because he wanted to show that he was so admiring a general that nobody could upset him.

D. Because he wanted to made the innkeeper know that a general like him had the same feeling as the ordinary people in face of danger.

【解析】 1. 此题为因果推断题。根据“Sir, we want nothing, ” said the innkeeper.“But will you tell us something?“ 可以看出来，这个店老板问拿破仑这个问题是出于好奇。他想知道作为将军的拿破仑与普通人到底有什么区别。故答案为A。

2. 因果推断题。从最后一句话“Now, you know the answer to the question you asked me just now, don't you?” 可以看出拿破仑并不想杀这个店老板，他这样做的目的是想让他体验一下他当时的感受。故可推出面对危险像拿破仑这样的将军与普通人没有什么两样。故答案为D。

Three men were discussing how to玠onate(捐献) money to God. At first they couldn't agree with each other, then they each told his own idea.

The first man said: “Let's draw a small circle on the ground and throw coins to the ground. The money out of the circle belongs to God.”

The second man added, “We will donate the coins inside the circle to God because God is in our hearts.“

The third man said: “Your ideas are not bad, but I have a better idea than yours. Let's throw coins into the sky. The coins that God accepts belong to him. So God can accept as much money as he can.”

At last, they agreed to the last idea, and they began to throw coins to the sky happily.

Imagine that the genome(基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.

Beldon and Canfield are two seashore towns, not far apart. Both towns have many hotels, and in summer the hotels are full of holiday瞞akers and othertourists(观光者).

Last August there was a fire at the Seabreeze Hotel in Beldon. The next day, this news appeared on page two of the town's newspaper. The Beldon Post: FIRE AT SEABREEZE

Late last night firemen hurried to the Seabreeze Hotel and quickly put out a small fire in a bedroom. The hotel manager said that a cigarette started the fire. We say again to all our visitors： “Please don't smoke cigarettes in bed.“ This was Beldon's first hotel fire for five years.

The Canfield Times gave the news in these words on page one：

ANOTHER BELDON HOTEL CATCHES FIRE

Last night Beldon firemen arrived just too late to save clothing, bedclothes and some furniture at the Seabreeze Hotel. An angry holiday瞞aker said, “An electric lamp probably started the fire. The bedroom lamps are very old at some of these hotels. When I put my bedside light on, I heard a funny noise from the lamp.

” We are glad to tell our readers that this sort of adventure does not happen in Canfield.

What are the facts, then? It is never easy to find out the exact truth about an accident. There was a fire at the Seabreeze Hotel last August: that is one fact. Do we know anything else? Yes, we know that firemen went to the hotel.

Now what do you think of the rest of the “news“ ?

1. The Canfield Times used the 玥eadline(标题)like this in order to make its readers think ___________.

B. hotels in Beldon don't often catch fire

C. this was the second fire at the Seabreeze Hotel

D. Beldon was a good place except that hotels there are not quite safe

1.非谓语动词的时态和语态形式（以动词do为例）：

一般式 主动 to do doing 动词的过去分词只有一种形式即done。及物动词的过去分词常表示被动和完成，而个别动词(多数是不及物动词)只表示完成

被动 to have been done having been done

进行式 to be doing ×

完成进行式 to have been doing ×

2. 非谓语动词在句子中的功能：

不定式 √ √ √ √ √ √ ×

_ing形式 √ √ √ √ √ √ √

过去分词 × × √ √ √ √ ×

一． 动词不定式的时态：

不定式的一般式通常表示不定式动作发生在谓语动词之后或与谓语动词同时发生；不定式的进行式（通常用于动态延续性动词）表示不定式动作与谓语动作同步发生；不定式的完成式通常表示不定式动作先于谓语动词而发生或表示一个实际未发生的动作；不定式的完成进行式往往强调不定式动作在谓语动词之前一直在进行。例如：

1. When I spoke to him, he pretended ___________(look) for something here and there.

2. He looked tired. He seemed ______________(work) all night.

3. Charles Babbage is generally considered ___________(invent) the first computer.

4. I would love _________ (go) to the party last night but I had to work extra hours to finish a report.

5. He ordered the man __________ (go) there at once.

二． 动词不定式的语态：

一般情况下，在一个含有不定式的句子中，如果有不定式的逻辑主语（即不定式动作的执行者）该不定式常用主动形式；如果出现的是不定式的逻辑宾语（即不定式动作的承受者），该不定式常用被动形式。但是，下面几种结构却常用主动表示被动：

(1).在easy, difficult, hard, heavy, light, fit, nice, comfortable等表示性质特征的形容词之后的不定式或用这些词修饰一个名词后跟的不定式常用主动表示被动；

(2).少数动词如blame(责备), let(出租)等的不定式作表语时常用主动表示被动。

6. This sentence is easy ___________ (understand).

7. I can’t go out with you today, as I have a lot of clothes_________ (wash).

8. “Have you any clothes __________ (wash) today?” asked the maid (女佣).

9.Our school is a nice place _________ (visit).

10. I found the chair comfortable _________ (sit) in.

11. I think the question difficult ________ (answer).

12. It’s I who am ________ (blame).

13. The officer ordered the soldiers ________ (fire) the guns.

14. The officer ordered the guns _________ (fire).

三._ing形式的时态:

_ing形式的一般式通常表示该动作与谓语动词同时发生或发生在谓语之后；完成式则表示

动作先于谓语动词而发生。如：

15. ________ (Walk) through the park, I saw some lovely flowers.

16. He was praised for __________ (teach) for 60 years.

17. I heard him __________ (sing) when I passed his room.

18. _________ (Finish) the work, he went home.

19. He insisted on _________ (join) the army.

四._ing形式的语态：

一般情况下，需要找准-ing动词的逻辑主语，若它们之间是主谓关系，-ing动词常用

主动；若它们之间是动宾关系，-ing动词就要用被动。但在动词need, want, require,及形容

词worth之后的-ing必须用主动表示被动。如：

20. He won’t come without __________ (invite).

21. The flowers in the garden need _______ (water).

22. Thank you for _________ (give) us so much help.

23. The building ________ (build) now will be a hospital.

24. ________ (give) such a good chance, how could she let it slip?

25. The book is well worth ________ (read).

动词不定式和动词的_ing形式都可以在句子中作主语。

（1）、一般来说，不定式作主语时，通常表示一次性的、特指的、具体的或将来的动作；而_ing形式作主语时，通常表示一个经常性的、泛指的、或不具体的动作。如：

26. ________ (refuse) him is not easy this time.

27. _________ (walk) is a good form of exercise for both the young and old.

28. ________ (teach) English is my job.

29. ________ (be) a teacher is her greatest wish in the future.

（2）、当句子的主语和表语都是非谓语动词时，两者在形式上一般保持一致；比较状语从句中的主语形式通常也取决于主句里的主语形式。如：

30. ______ (see) is to believe.==________ (see) is believing.

31. ________ (say) is easier than to do.

32. ________ (speak) a foreign language is more difficult than reading it.

（3）、在日常英语中，为了句子结构的平衡，常用it作形式主语而将不定式或-ing放在句末

这时候要注意下面的习惯句型：

It + be + 形容词或名词+ (for / of sb.) + to do sth.

It + take + sb. +some time / sth. + to do sth.

It + be + no use / no good / useless / a waste of sth. / worth + doing sth.

There + be + no + doing sth. (做某事是不行或不可能的)

33. It was foolish of you _________ (give) up what you rightly owned.

34. There is no ________ (hold) back the wheel of history.

35. I think it’s no good _______ (argue) with your parents.

动词不定式和动词的_ing形式都可以在句子中作宾语。

（1）、有些及物动词后只能接动词不定式作宾语，不能接-ing形式，常见的有：hope, wish, expect, decide, promise, offer, agree, manage, pretend, plan, refuse, fail 等等。

（2）、有些及物动词后只能接动词的_ing形式作宾语，不能接不定式，常见的有：enjoy, imagine, risk, appreciate, suggest, advise, admit, miss, practise, forbid, avoid, resist, escape, delay, finish, permit, allow, mind, keep, consider, excuse 等等。

（3）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义相同，常见的有：begin, start, continue, intend, bear, attempt等等。但要注意，begin, start 如遇下面三种情况时接不定式为最佳：

A. 句子的主语是物而不是人时，如：The ice began to melt.

B. 当begin, start 用了进行时态时, 如：He’s beginning to understand it.

C. 当begin, start 后作宾语的动词属于心理活动、精神状态类动词（如realize, understand, love, like, know 等等）时，如：It began to rain and I began to realize I should go home.

（4）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义有细微差别，常见的动词有：like / love / prefer / hate to do sth.(表示一个特定的、一次性的、将来的动作)

like /love / prefer /hate doing sth. (表示一般的、习惯性的、或正在进行的动作)

36. I like _________ (swim) but I don’t like _______ (swim) today.

37. Would you love ________ (go) to the zoo with us?

38. I felt like _______ (cry) at the news.

（5）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义完全不同，常见动词有：

39. We must try ________ (finish) the work on time.

Let’s try _______ (work) out the maths problem in another way,

40. I remember ______ (see) her somewhere before.

You must remember _______ (post) the letter for me.

41. He forgot ______ (pay) and asked to be paid again.

44. I can’t help ________ (do) housework today. I’m busy preparing a report.

I couldn’t help _________ (think) of my childhood while seeing the film.

45. When the teacher came in, the students stopped _______ (talk).

46. Though it was raining, the peasants went on ________ (work) in the fields.

After listening to the text, we went on _______(read).

47. The baby needs ______ (look) after. =The baby needs ________ after.

You don’t need _______ (look) after the baby today.

48. Our school is well worth ________ (visit).

Our school is well worthy ________ (visit).= Our school is well worthy of _________.

（6）、介词后的宾语一般用动词的-ing形式，但要注意：but和except之后通常接不定式；介词之后若有连接词时也要接不定式。如：

49. I have no choice but _______ (wait).

50. He gave me some advice on how _______ (study) it well.

51. He has no idea of what _______ (do) next.

52. I was about ______ (go) out when it began to rain.

注意：A. 下面短语中的to是介词，后面要接动词的-ing形式而不接不定式。

devote---to---, look forward to, pay attention to, prefer---to---, lead to, be close to, refer to, belong to, as to, get down to, owing to, be / get /become used to(习惯于------),等等。

B.有些短语中介词经常省略，这时要注意接动词的-ing形式，如：be busy (in) doing sth., spend money /time (in) doing sth., have difficulty /trouble / problems (in) doing sth., prevent / stop ---(from) doing sth.,等等。

（7）、当不定式和_ing形式作“主语+谓语+宾语+补语”句型中的宾语时，要用it作形式宾语，把真正的宾语置于补语之后，常见句型有：

主语+ make / feel /think /find /consider, etc. + it + adj. / n. + (for / of sb.) + to do sth.

主语+ make /feel /think /find /consider, etc. + it + no good /no use /useless + doing sth.

所有的非谓语动词都可以在句子中作表语，其区别在：

（1）、不定式作表语通常表示一次性、特指的、将来的或具体的动作，有时还可以表示计划安排将要发生的事或一种命令要求。

（2）、-ing形式作表语通常表示习惯性、泛指的、不具体的动作或表示主语的性质特征（主要是一些表示感情情绪的词，译为“令人感到……的”）

（3）、过去分词作表语通常表示主语所处的状态，常具有被动含义（主要是一些表示感情情绪的词，译为“感到……的”），这样的动词常见的有：surprise, move, excite, interest, shock, tire, bore, touch, encourage, disappoint, invite, inspire, amuse等等。如：

53. No one is ______ (leave) this building without the permission of the police.

54. My job is ______ (teach) English and my wish is ______ (be) a lawyer.

55. The president is ______ (visit) our country next month.

56. The speech was very _________ (move) and we were all _______ (move) to tears.

所有的非谓语动词都可以作定语，其区别在：

（1）、不定式作定语常放在被修饰的名词之后，通常可以表示：

A. 一个发生在谓语动词之后的动作。如：

The building to be built next month will be a hospital.

B. 被修饰的名词与用作定语的不定式之间可能是逻辑上的“主+谓”关系，也可能是逻辑上的“动+宾”关系。如：

Do you have anyone to help you? (“主+谓”关系)

I have nothing to write. (“动+宾”关系) 我没有什么东西可写。

C. 如果是“动+宾”关系，动词不定式之后有时需要添上适当的介词，而在名词time, place, moment, way等之后的不定式所带的介词可以省略，如：

I have nothing to write on. 我没有什么东西可以上面写字。

I have nothing to write with. 我没有什么东西可以用来写字。

I have no time to rest.

注意：这种带介词的不定式短语常可以转换为“介词+which / whom+不定式”的结构。例：They had only a cold room to live in.==

They had only a cold room in which to live.

D. 下列情况常用不定式作定语：

当句子中的谓语是一些特定的动词，如：be, find, get, give, have, need, want等，它们后面的名词（宾语或表语）常用不定式修饰。

当名词前有特定的定语，如：first, last, next, only, second以及形容词最高级时，其后常用不定式作定语。

在There be句型中，主语之后常用不定式作定语。

有一些特定的名词之后常用不定式作定语，常见的有：time, chance, right, promise, wish, plan, means, ability等。

例：You have no right to speak here.

He is the only person to know the truth.

There is nothing to worry about.

My parents had no chance to go to college.

（2）、动词的_ing形式作定语时，如果是单个词，常放在被修饰名词之前；如果是-ing短语，要放在名词之后。_ing作定语通常可以表示：

A. 被修饰名词的用途，如：a sleeping car, a waiting room, a walking stick, etc.

B. 被修饰名词的性质特征，如：exciting news, a moving story, etc.

C．被修饰名词正在进行的动作，如：a falling leaf, a burning stick, boiling water, etc.

（3）、过去分词作定语通常表示：

A. 被动，如：He is a man loved by all the people.

B. 完成，如：The building built last year is our classroom building.

a fallen leaf, a developed country, boiled water

C. 被修饰名词所处的状态，如：an excited boy, the disappointed parents, surprised eyes, etc.

所有的非谓语动词都可以在句子中充当状语，其区别在：

（1）、不定式（短语）常在句子中作目的、结果和原因状语，常见句式有：

目的：to do sth.; in order to do sth.; so as to do sth.

结果：so + adj. /adv. + as to do sth.; such + n. + as to do sth.; enough to do sth.; too…to do sth.; only to do sth.

原因：be happy / glad / sorry / sad ,etc. + to do sth.

（2）、_ing形式和过去分词位于句首时常作时间、原因、条件状语，位于句末时主要作方式、伴随或结果状语。究竟该用_ing还是过去分词，主要取决于句子的主语，若它们之间是主动关系就用_ing形式，若是被动关系，就用过去分词。

57. He raised his hand ________ the taxi stop. (have)

58. _______ from the top of the hill, our school looks more beautiful. (see)

59. The parents died, _______ him an orphan. (leave)

60. ______ to college, he works very hard. (go)

61. I’m not such a boy as ______ him. (believe)

62. _______ ill, he was sent to a hospital. (be)

注意：A. 非谓语动词作状语时，其逻辑主语通常是句子的主语，如：

（×）Being a fine day, we went out for an outing.

（√）As it was a fine day, we went out for an outing.

（√）It being a fine day, we went out for an outing.

(×) Hearing the news, tears came to my eyes.

（√）Hearing the news, I burst into tears.

（√）When I heard the news, tears came to my eyes.

B．有些非谓语动词可以相当于独立成分、介词或连词使用，这时候它们常有自己固定的形式，与句子的主语不存在任何的逻辑关系，常见的有：

to tell (you) the truth, to be honest, (老实说)

generally / strictly / exactly speaking (一般/严格/准确地说)

including (其中包括……) compared with / to… (与……相比)

所有的非谓语动词都可以作补语，在使用中要注意下面几种情况：

（1）、有许多动词，如：ask, tell, allow, force, cause, encourage, 等之后都可以接不定式作宾语补足语。

（2）、在感官动词notice, observe, feel, hear, listen to, see, watch, look at之后可以接三种非谓语动词作补语，其区别在：_ing作补语表示与谓语动词同时进行的动作，如果这个动作与宾语是被动关系，还要用其被动形式being done；过去分词作补语常表示一个完成被动的动作；不定式作补语可以表示一个全过程、一个具体的、将来的、或经常性的动作。如：

63. I saw the classroom ________ (clean) when I passed by it.

64. The missing children were last seen ______ (play) by the river.

65. I often hear him ________ (sing) in the next room.

66. I saw the room _________ (clean). Everything was put in order.

67. I saw him ________ (open) the door, _______ (walk) into the room, and ______ (sit) down at the desk.

（3）、注意使让动词之后的补语用法：

A．have sb. do sth.==get sb. to do sth. “请/叫/让某人做某事” 与宾语的关系是主动的。

B．have sb./ sth. doing sth.“使某人一直做某事/容许某人做某事”，强调主动和进行。

C．get sb. doing sth.“使某人开始做某事”。

D．have sb./sth. done ==get sb./sth. done“使某人/某物被……或使……遭受……”，表示被动

E．make /let sb. do sth.表主动。

F. make /let sb. /sth. /oneself done 表示被动。

（4）、有些动词后不能接非谓语动词特别是不定式作宾语补足语，常考的动词有：agree, refuse, hope, suggest, demand, etc.

(5)、有些动词后需要接_ing作宾语，而接不定式作宾语补足语，常见的动词有：advise, allow, permit, forbid, encourage等。

例：68.You’d better have someone else _______ (help) you. I’m too busy.

69.He already had his eyes ________ (examine) in the hospital yesterday.

70.The speaker explained it again to make himself _______ (understand).

71.We don’t allow _____ (smoke) in our classroom.

72.He didn’t allow his son _____ (play) computer games.

动词的_ing形式常被用来解释一个名词的具体内容，在句子中充当同位语，如：

His habit, studying at night, remains unchanged.

The gesture for “OK”, making a circle with one’s thumb and index finger, has different meaning in different countries.

一、 否定结构：

所有非谓语动词的否定结构都是在非谓语动词前直接加否定词not或never等构成。

例：Excuse me for not coming back in time.

Not having received a reply, He decided to writer again.

He advised me never to go out alone at night.

不定式复合结构是指带有主语的动词不定式，其形式有以下两种：

（1）、for sb. to do sth.(侧重动作), 可以用于各种句子结构中。

（2）、of sb. to do sth.(侧重对逻辑主语品行的评价)，这种结构主要用于下列形容词之后：bad, brave, careful careless, clever, foolish, cruel, kind, rude, polite, stupid等。

73.It’s very important ____ us to learn English well.

74.It’s very foolish ____ you to believe him. == You are very foolish to believe him

75.There are a lot of difficulties ____ them to overcome.

76.I stepped aside ____ her to pass.

由动名词的逻辑主语和动词_ing一起构成，在句子中主要作主语和宾语，其形式有：

注意、A、当句子的主语就是_ing动词的逻辑主语时不能用复合结构。如：

Would you mind opening the door? (You open the door.)

Would you mind my / me opening the door? (I open the door.)

B、_ing作主语放在句首时，只能用第（1）种形式的复合结构。如：

His being ill made us very sad.

C、当无生命的名词或两个以上的名词/代词并列作_ing的逻辑主语时，只能用第（2）种形式的复合结构。如：

Can you hear the noise of the machine running.

Is there any hope of him and his sister winning the prize?

（1）、由“名词或代词主格+动词的_ing形式或过去分词”构成，在句子中作状语，可以表示时间、原因、条件、伴随情况或方式。主要用于句子的主语不是非谓语动词的逻辑主语时。如：

77.All the work_______ (do), he had a rest. （时间状语）

78.Weather ________ (permit), we will go outing tomorrow.（条件状语）

79.The boy stood there, his right hand _______ (raise). （伴随情况）

80.He _____ (be) ill, we sent him to a hospital. （原因状语）

81.There ______ (be) no buses, we had to walk home.（原因状语）

（2）、由“with/without +名词/代词宾格+动词_ing /过去分词/不定式/介词（短语）/形容词/副词”等构成，在句子中可以作状语或定语。如：

82.The murderer was brought in, with his hands _____ (tie) behind his back.

83.With a lot of work ____ (do), I can’t go to the cinema with you.

84.He left without anybody ______ (know).

五、“连接词+ to do”，“when/while/though/unless/if, etc. + done /doing”结构的区别

（1）、“连接词+to do”相当于一个名词的作用，在句中作主语、宾语和表语，常可以转换成由该连词引出的从句。

(2)、“when/while/though/unless/if, etc. + done/doing” 在句子中只能作状语，主句的主语是此结构中doing和done的逻辑主语，如果它们之间的关系是主动的，就用doing，是被动的就用done。

85. Please tell me what _______ (do ) next. ==Please tell me what I should do next.

86. The problem is whether _______ (go) by bus or by plane.

87. When ______ (start) the project hasn’t been decided yet.

88. Be careful when / while ________(cross) the street.

89. When________ (heat), ice will melt.

90. He won’t go to the party unless _______ (invite).

一、 省略不定式符号to的情况：

(1).不定式在感官动词notice, observe, feel, hear, listen to, see, watch, look at, 和使让动词have, make, let 之后作宾语补足语时，符号to必须省略。但是当这些动词用于被动语态时，动词不定式变为主语补足语，符号to不能省略。

例：We often hear him sing the song at home.→ He is often heard to sing the song at home.

(2).在动词help之后作宾语或宾语补足语的不定式，符号to可有可无。

(3).两个或两个以上的不定式由连词and / or / than / but 等连接时，从第二个不定式起的符号to常常省略。

例：The students are taught to read, write and do many other things.

例：It’s more difficult to do than to say.

The teacher came not to punish you but to help you.

I wondered whether to stay or to leave.

(4).不定式作表语，用来解释主语部分中do的内容时可以不带to。如：

What we want to do now is (to) lie down and rest.

The first thing she did was go up to her trainer and thank her.

(5).在why或why not引起的表示建议或责问的省略问句中不能带to。

Why quarrel with your mother? Why not join us?

(6).在一些类似情态动词的词组如：had better, would rather … than … , can’t (help / choose) but 等之后的动词不带to。

(7).不定式作but或except的宾语时，若前面有实意动词do / does / did / to do等形式，不带to。如：

I did nothing but / except do my homework last night.

She had nothing to do but wait.

(8).当助动词do / does / did用来加强语气或构成倒装句时，其后的动词不能带to。如：

Seldom does he go home this term. I did tell him the news.

(9).当dare用作实意动词时，后面的不定式有时也不带to，特别是在否定句中。

She didn’t dare (to) ask the teacher.

(10).在美国口语中，用在祈使语气中表示目的，在动词come / try / go / run等之后的不定式可以不带to。如：

Come tell me if he arrives. Go tell your mother. Try open the door again.

二、 省略to之后的动词部分的情况：

一般说来，当不定式内容是重复前面的内容时，to后的成分可以承前省略，但要保留符

号to，此时省略的成分相当于do so，这种结构一定要有上文或一定的语境。如：

_ Will you go with me? _ Well, I’d like to.

_ Why didn’t you bring an umbrella with you? _ I meant to, but I forgot about it.

The boy wanted to ride his bicycle in the street, but his mother told him not to.

He can’t eat as much as he used to.

注意：当不定式内容是助动词be / have时，to后要保留原形的be / have。如：

He hasn’t succeeded in the exam, but in fact he ought to have.

She is no longer what she used to be.

1. It shames me to say it, but I told a lie when _______ at the meeting by my boss.

Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social uest in some areas. But who is responsible for the current world food crisisFirst, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problemOn one hand, we should focus on the environmental protection and improve the ecology. On the

other hand, strict measures should be taken to protect farmland. Of course, to

build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.As for me, I will call on the people around me to live thriftily. And for the

moment, I think, we should study hard to develop science and help solve the food shortage in the future.

高三英语复习课件 篇10

高三英语专题复习教案――基础写作    教学重点：如何审题；如何进行信息整合；上下文的承接。   教学难点：写作思路及方法的培养   教学方法：讲练结合，精讲多练，引导学生体会与模仿。   教学目标：学生进一步熟悉基础写作的特征和基本要求，培养正确的写作思路及方法，掌握常用的写作模式和句型。消除对写作的恐惧心理，培养写作兴趣。    一、基础写作题的特点 高考设置基础写作题的目的是要检测考生最基础的书面语言表达能力，如用词的合理性、句子结构的复杂度、语法运用的正确性、信息内容的完整性、句子之间的连贯性等。因此，基础写作题与往年的书面表达依然会有很多相似点，但也会出现一些新的特点。   1．写作题材贴近考生的学习和生活。历年来高考作文题的题材都非常贴近考生的学习和生活，如校园活动、校外见闻、交友、旅游、以及与考生有关的话题讨论等。可以预料明年高考写作题的题材还会在这些范围内，并为所有考生所熟悉。 2．写作的题材主要是故事性描述和应用文。历年的基础写作题的题材也会与往年书面表达相似，主要有故事性描写和应用文写作两大类。命题形式可能是看图写故事、看图表说明、根据表格信息完成一封短信或一份通知这类的应用文等。 3．内容呈现的方式具有半封闭性。作文试题逐步走向开放将是大势所趋。但是，基础写作题还只能是半封闭的，其特点是写作的内容是被规定了的，考生必须将文章所规定的信息点完整、全面地表达出来，但对于语言表达的方式、信息组织的先后秩序、需要补充哪些必要的信息等，考试又有一定的自主构思空间。 4．用5句话表达。这是基础写作题与往年书面表达题最显著的不同点。往年是规定字数（100词左右），句子的数量不作规定，所以很多考生为了不犯句法错误总是使用一些简单句。而历年的基础写作只能用5句话来表达题目所给的全部信息点，但所给的信息点与往年的书面表达相比并不会减少，所以，用5个简单句很难完成任务，必须使用复合句或并列句来综合多个信息点，而且还要照顾句子之间的衔接和语意上的连贯。从只一点来说，基础写作题对考试运用语言能力的要求大大提高了。     二、基础写作题提出的新要求  1．信息组织能力。信息组织能力包括信息归类、信息排列和信息表达三个环节。对于题目所提供的各种信息点，考生首先需要依照一定的标准将信息进行归类，并初步计划将哪些信息放到同一个句子中；其次是将信息进行合理的排列，排列必须依照一定的标准，如时间顺序、空间顺序、因果关系、递进关系等；第三是选择表达的秩序，确定句子之间的先后顺序，这既要考虑语句上能否衔接，还要考虑语意上的连贯。在组织信息的过程中，还要对某些信息进行必要的增删，使文章意思连贯、语言畅谈、逻辑严密。 2．运用复杂句子的能力。在整理和归类信息点之后，就需要正确地使用比较复杂的句子，综合的表达信息。复杂句子主要有三类： 第一类是复合句或含有非谓语动词、介词短语的复杂句。复合句主要有三类：含有名词性从句的复合句，含有状语从句的复合句，含有定语从句的复合句。 第二类是并列句或带有并列成分的复杂句。连接并列句或并列成分的并列连词主要有四类：表示意义引申的并列连词，如and，both… and，not only…but also，and… as well，not… nor，neither… nor等；表示选择的并列连词，如or，whether… or，either… or等；表示转折或对比的并列连词，如but，while，whereas，only等；表示因果关系的for。此外，therefore，besides，however，nevertheless，moreover，furthermore，what’s more，in addition，on the contrary，after all等连接性状语也可以在句子之间起连接作用，表示分句之间的并列关系。 第三类是一些特殊句型，如使用强调句、倒装句、含有with复合结构的句子、there be开头的句子、以形式主语it 开头的句子等。 正确使用各种句型，不仅能够完成题目所要求的任务，还能使文章的句式变得丰富、行文更加流畅、中心和主旨更加突出。     三、基础写作题的备考策略 在基础写作的备考过程中，一方面要重视养成一些良好的写作习惯，如认真审题、巧妙构思、常写草稿、工整书写、仔细核对等好习惯，另一方面在组织信息和训练复杂句子结构方面要多下工夫。下面以“广东省普通高等学校招生全国统一考试广东省英语科考试说明”中的样题为例，探讨如何备考基础写作题。 第一节：基础写作（共1小题，满分15分） 假设你最近参加了由某电视台举办的中考生英语演讲比赛并获奖，该台准备组织获奖者去北京参加一次英语夏令营活动，下表是这次活动的时间安排和活动内容。 活动时间 7月15日 ― 22日或8月15日― 22日 活动内容 参加英语角  学唱英语歌曲  听英语讲座  表演英语短剧 看英语电影  教外宾学中文   【写作内容】   电视台就活动时间和活动内容征求你的意见。请按照以下要求用英语以书信形式给予答复。 1．选择适合你的时间并说明理由； 2．解释你只能参加其中的两项活动（听英语讲座和教外宾学中文），虽然你认为所以的活动都很有意义； 3．说明你选择的理由：听英语讲座了解英美文化的信息；教外宾学中文因为北京奥运会让越来越多的外宾想了解中国。 【写作要求】 1．必须使用5个句子表达全部内容 2．信的开头和结尾已给出。 Dear Sir or Madame, I’m glad to be invited to the English summer camp. ……. Thank you very much.   Yours truly, Li Ping   【评分标准】   语       言 7 ― 8 具有很好的语言运用能力；语法和句子结构准确性高，词汇方面使用较好，只有少许错误。 5 ― 6 具有较好的语言运用能力；语法和句子结构准确性较好，有一些语法结构或词汇方面的错误，但不影响理解。 3 ― 4 语言运用能力一般；语法和句子结构基本准确，语法结构或词汇方面的错误不影响理解。 1 ― 2 语言运用能力较差；语法和句子结构基本不正确，语法结构或词汇方面的错误较多，而且影响了对句子意义的理解。 0 语言运用能力很差；语法、句子结构、词汇错误很多，句子意义无法理解。 备注 每多写或少写一个句子，扣1分。 内     容 5 包括了所有信息内容 4 包括了大部分信息内容 3 包括了基本信息内容 2 包括了小部分信息内容 1 包括了少许信息内容 0 没有包括所提供的信息内容 连   贯 2 内容连贯，而且结构紧凑 1．5 内容连贯性比较好，而且结构比较紧凑 1 内容连贯性教差，而且结构不够紧凑 0 内容缺乏连贯性，而且结构松散 备注 文不对题，给0分   由此我们可以看出，信息点的数量与往年的书面表达题相比并没有减少，要想用5个句子把所有的信息都表达出来，考生必须从以下三个方面进行备考：   1．养成重视审题的习惯。虽然基础写作题是半封闭性的，但审题仍然十分重要。现以样题为例，谈谈如何审题：   思考的问题 样题分析 要写的文章主题是什么？ Topic 参加夏令营 为什么要写这篇文章？ Purpose 电视台邀请参加夏令营，写信回复。 要写文章的信息点有哪些？information items 选择的时间，参加活动的内容，解释什么 怎样安排信息点的'逻辑顺序？ order 说明要参加的活动并解释原因→说明要参加的时间并解释原因。 动作是什么时候发生的（时态）？when 夏令营还没有开始，文章主要用一般将来时     2．提高组织信息的能力。组织信息的过程包括信息分类、信息排列、和信息表达三个环节。这些步骤看起来好像很繁琐，但对于中下成绩的考生来说，一步一步地思考这些问题是很有必要的。现以样题为例，说明该怎样组织信息。   信 息 分 类 时间信息：两个时间段 内容信息：6项活动 选择信息：其中的两个活动及其理由 信 息 安 排 夏令营的内容信息点安排：可以将自己要参加的两项活动放在前面，其它信息点可以略写。 作者的选择信息排列：依照自己所参加的活动顺序逐项表述，紧接着给出选择的理由。 信 息 表 达 结合已经给出的头和尾，写作的顺序安排如下：很高兴被邀请（已给出）― 感谢安排这么多的活动 ― 说明活动的意义 ― 表达自己只能参加两项活动的遗憾和原因 ― 说明参加的活动内容及原因（两项活动用一句话）― 说明自己选择的时间及原因     3．夯实基础，掌握基本的句子结构及其用法。对于大多数考生来说，用词不准和句子结构错误是写作失分的“罪魁祸首”。夯实基础、掌握基本的句子结构及其用法是基础写作备考的主要任务，完成这项任务可以分步骤进行：   教学内容与过程： Step one: Greetings and dictation Step two: 讲练结合，并就学生作文较常出现的错误进行点评，讲评过程注意把握好学生作文中的常见的非智力因素方面的失分。 Step three: 就学生作文中出现的常见错误进行适当的点评。 Dear Sir or Madam, I’m glad to be invited to the English summer camp. ① Thank you very much for arranging so many activities, such as English corner, English lectures, English films, English songs, English plays and helping foreigners learn Chinese. ② I am sure all the activities will do a lot of good to us students. ③ But it is a pity that I can only take part in two of them, because I will have to spend some time in doing my research project. ④ I would like to listen to the lectures, by which I will learn some about western culture, and help

高三英语复习课件 篇11

以下50句写作句型与考研写作考察的炙热话题相关，可以作为写作的论证素材。建议考生在考前进行训练。训练的方法是先独立将中文转化为英文，然后对照参考译文，自查错误，对自己的译文进行改正，并学习参考译文中较好的句型、词汇等。最后要对好的语言素材进行背诵记忆。

1.涉及北京机动车使用量增加这一问题，有的人认为应该限制使用。另一些人持相反意见。

也许双方的观点都有一定道理，但是，无论车辆多少，必须对废气排放实行控制。

When it comes to the increasing use of motor vehicles in Beijing, some people think that use should be limited.Others argue that the opposite is true.There is probably some truth to both arguments, but emission controls must be instituted regardless of the number of vehicles.

2.目前，针对流动工人的问题展开了普遍的争论。反对流动工人增加的人认为这会导致犯罪率升高，从而危害社会稳定。他们主张应该严格限制进入中国城市的流动工人。但是，另一方面，支持廉价劳动力流入的人主张，为了支持大规模的城市基础设施建设规划，流动人口是必需的。

There is a general debate nowadays about the problem of itinerant workers.Those who object to the rising migrant population argue that increasing numbers lead to rising crime rates and harm social stability.They believe that strict limits should be placed on migrants entering China’s cities.But people who favor the influx of the cheap labor force, on the other hand, maintain that migrants are needed to support the massive urban infrastructure construction program.

3.人们普遍认为过度砍伐造成了夏季特大洪水。专家认为中国必须推行大规模的植树造林计划。但我对仅仅植树造林就能解决问题表示怀疑。

It is widely acknowledged that extensive deforestation contributed to heavy summer flooding.Experts argue that China must introduce a massive forestation program.But I doubt whether forestation alone will solve the problem.

4.大多数人认为财富为所有问题提供解决的办法。但是，我认为，尽管财富提供物质上的利益，一个人应该放弃物质至上的追求，而是集中精力追求幸福。

Most people are of the opinion that wealth provides solutions to all problems.But in spite of the material benefits wealth provides, I believe one should abandon the pursuit of materialism and instead concentrate on the pursuit of happiness.

5.越来越多的人通过互联网进入了“信息时代”。针对这一现象，一些人认为互联网消除了障碍，为人们提供了与世界即时链接的途径。但是，他们有没有意识到迅速发展的信息技术也能导致侵犯隐私?

An increasing number of people are joining the “Information Age” via the Internet.In reaction to the phenomenon, some say the Internet has removed barriers and provided people with immediate access to the world.But do they realize that rapidly advancing information technology can also lead to intrusions of privacy?

6.最近，我们经常听到贫富差距扩大了的说法。一些人认为发达世界完全忽略了这个问题。事实是这样吗?细致的调查无法证实这一观点。

These days we often hear about the widening gap between the rich and poor.Some argue the developed world has totally ignored the problem.But has it? Close examination fails to bear out the argument.

7.我们经常被告知世界处于毁灭的边缘。但事实真是这样吗?

We’re often told that the world is tethering on the brink of destruction.But is this really the case?

8.许多人谈论的一个最严重的问题集中在缺乏足够的居住空间。

One of the most serious problems many people talk about centers on the lack of adequate housing space.

9.也许当今困扰国家的最危险的现象是遍布各级政府的官员腐败。

Perhaps the most dangerous phenomenon gripping the nation today is official corruption, which is pervasive in all levels of government.

Never before in history has the issue of overpopulation been more evident than now.

12.越来越多的人开始意识到财富不是幸福的唯一先决条件。

A growing number of people are beginning to realize that wealth is not the sole prerequisite for happiness.

13.尽管科学技术取得了非凡的进步，但是在保证进步成果使尽可能多的人受益这方面还存在一些问题。

In spite of the extraordinary progress made in science and technology, problems remain in terms of guaranteeing that achievements benefit the greatest number of people.

14.一位著名的思想家曾经写道：“对人类最大的威胁是人类自身!”如果事实确实如此，那么，现状应该促使我们对我们未来的生存进行思索了。

A famous thinker once wrote that “the greatest threat to mankind is mankind itself!” If this is indeed the case, then the current situation should make us ponder our future existence.

15.对人们行为的多年观察使我能够得出这样的结论：平庸和成功的主要区别仅仅在于相关的个人。成功的个人不断寻求进步，而他们比较懒惰的同时代人仅仅满足于现状。

Years of observing human behavior has enabled me to conclude that the major difference between mediocrity and success lies solely with the individual concerned.Successful individuals consistently seek advancement, while their less industrious contemporaries are merely content with the status quo.

16. 传统的思维方式有了显著的变化。舆论发生了剧变，人们表现出更开放的思想以及决定他们自己命运的强烈愿望。

Traditional ways of thinking have changed dramatically. The pendulum has swung and people are exhibiting greater open-mindedness and a burning desire to determine their own destiny.

17.近年来出现了对社会有害的拜金主义倾向。最近的一项调查表明，X%的调查对象把致富作为他们的首选，相比之下，就在几年前，只有X%的人这样想。为什么人们没能意识到财富不一定带来幸福呢?

There has been undesirable trend in recent years towards the worship of money. A recent survey showed that X percent of respondents ranked getting rich as their top priority, compared to X percent only a few years ago. Why do people fail to realize that wealth does not necessarily bring happiness?

18. 几个月前，我的一个朋友死于一场与酒后驾车有关的悲惨车祸。这件事情一点儿也不罕见，事实上是数以千计的案件的典型，这些案件与在酒精作用下开车的人有关。

Some months ago, a friend of mine was killed in a tragic automobile accident involving a drunk driver. The incident was far from rare, and was in fact typical of thousands of cases involving people driving under the influence of alcohol.

19. 简而言之，我们必须勤奋工作，为了下一代把世界变成更美好的地方。我们不应该坚持对环境有害的追求。

In short, we must work diligently to make the world a better place for coming generations. We must not persist in pursuits harmful to the environment.

20. 我们必须避免过分放纵和铺张浪费。相反，我们应该继续发扬节俭的优点以守护我们新获得的繁荣。

We must avoid overindulgence and conspicuous consumption. We must instead continue to recognize the benefits of thrift in order to protect our newfound prosperity.

21. 获得成功说起来比做起来容易，然而坚持不懈确实会有好结果。成功人士的最重要的特征之一是自信，第二是渴望，还有一个是决心。

While achieving success is easier said than done, persistence does in fact pay off. One of the most important traits of a successful person is self-confidence, another is desire, and still another is determination.

22. 认识到问题是找到解决办法的第一步。

Recognizing a problem is the first step in finding a solution.

23. 我们应该感谢许多为把世界变得更美好而奉献一生的人。然而，我们不能依靠他们的成绩，而必须努力工作，取得更辉煌的成就。

We owe a debt of gratitude to the many individuals who dedicated their lives to making the world a better place. However, we must not rest on their accomplishments, but must instead work assiduously to record even greater achievements.

24. 现在，中国面临的两大挑战是保持持续的经济增长和靠世界上仅仅百分之七的可耕地养活仍在增长的12亿人口。尽管遇到的困难很大，中国人无疑会表现出不知疲倦的活力，在两方面都取得巨大成功。

The two major challenges facing China today center on maintaining sustained economic growth and feeding its growing population of over 1. 2 billion people with only seven percent of the world’s cultivable land. Despite the monumental difficulties involved, Chinese people will undoubtedly exhibit their indefatigable resilience and achieve great success in both regards.

25. 事实上，我们达到最终的目标还有很长的路要走，但是，取得一些成绩还是可能做到的。

We do, in fact, have a long way to go to reach our final goal, but achieving some remains well within the realm of possibility.

26. 为什么越来越多的中国老人不和他们的孩子住在一起?原因之一是年轻一代的上进心增强了。另一个原因是社会上老人的机会增加了。然而，主要的原因可能是传统观念发生了巨大变化。

Why are an increasing number of elderly Chinese parents living apart from their children? One reason is the increasing upward mobility of the younger generation. Another is expanding social opportunities for the elderly. Perhaps the main reason, however, centers on dramatic changes in traditional concepts.

27. 什么引发了人们对锻炼越来越浓的兴趣?一方面，人们更加清楚地意识到保持身体健康的必要性。另一方面，不断提高的生活水平使中国人能够支付增加的娱乐支出。最主要的可能在于锻炼带来的保健和心理上的好处。

What has sparked the increasing interest in exercise? For one thing, people have gained a greater awareness of the need for physical fitness. For another, the constantly improving standard of living enables Chinese people to patronize the increasing number of recreational venues. The main thing perhaps centers on the healthcare and psychological benefits exercise provides.

28. 要找到涉及许多复杂因素的新现象的原因远非一件易事。例如，一些科学家把环境的恶化归结为一些自然因素，而另一些人把责任都推到人类不适当的行为上。

Identifying the reasons for an emerging phenomenon which involves several complicated factors is far from an easy task. For example, some scientists attribute environmental deterioration to a series of natural factors, while others place the blame solely on inappropriate human behavior.

29. 对上升的少年自杀率的解释涉及很多复杂的因素。有的人把上升的原因归结为过分强调少年时期的成功，有的人指出是因为不断增长的同伴之间的压力，还有人认为是对不断变化的社会价值的迷茫造成的。

The explanation for the phenomenon of the rising teenage suicide rate involves many complicated factors. Some attribute the rise to an overemphasis on early success, others point to mounting peer pressure, and still others to confusion over changing social values.

30. 儿童的发展取决于很多因素，包括生理的和心理的。从婴儿期到青春期的正确的家长教育决定一个成熟的个人的体质及智力的状况。

Child development depends on a number of factors, both physical and psychological. Correct parental nurturing from infancy through adolescence determines both the physical and mental profile of a mature individual.

31. 自信、雄心，加上决心和毅力等因素是造成最终的成功或失败的原因。

Factors such as self-confidence and ambition, combined with determination and willpower, contribute to eventual success or failure.

32. 如今人类最常见的一个不足是不说真话。人们必须意识到不说真话、说谎话在过去没有，事实上，将来也永远不会变错误为正确。

One of the most common failures of people today is to avoid telling the truth. People must realize that avoidance and lying have never in the past and, in fact, never will right a wrong.

33. 声称缺少机会不过是敷衍失败的借口。通常，失败最根本的原因是相关的个人本身缺乏动力。

Claiming a lack of opportunities is nothing more than a superficial excuse for justifying failure. The fundamental reason for failure is most often the lack of drive on the part of the individual involved.

34. 我们可以，而且经常因个人的失败抱怨我们的同时代人，但是，事实是许多问题的根本原因要深刻得多。

We can, and quite often do, blame our contemporaries for personal failures, but the fact of the matter is that the root causes for most problems go much deeper.

35. 虽然全球变暖这一长期的问题确实很严重，但考虑到诸如环境的迅速恶化和不可更新资源的'普遍滥用等当前的问题，它的重要性就有所降低了。

While the long-term problem of global warming is indeed serious, its significance diminishes somewhat when considering immediate problems such as rapid environmental deterioration and the rampant misuse and abuse of nonrenewable resources.

36. 与拥有一辆自行车相比，人们更愿意拥有一辆汽车，但拥有后者涉及的问题远远超过前者。原因之一，汽车昂贵很多，需要更多的维护。原因之二，自行车不会引起污染。

Owning a car might be preferable to owning a bicycle, but the problems associated with owning the former far outweigh those of the latter. For one thing, automobiles are exponentially more expensive and require greater maintenance. For another, bicycles don’t pollute.

37. 从成功的角度来说，良好的职业道德与教育同等重要。事实上，成功的确建立在两方面完全融合的基础上。

From the standpoint of success, a good work ethic is no less important than an education. Success does, in fact, depend on the total integration of both aspects.

38. 改善教师的困难处境的确是优先处理的一件事情。但是，改进整个教育系统同等重要。

Improving the plight of teachers is indeed a priority item. However, improving the overall education system is likewise no less important.

39. 无论结果如何，我们必须坚定地继续为目标而努力。

Whatever the outcome, we must resolutely precede with our objective.

40. 无论成功的决心多么坚定，成功的要求多么强烈，一个人永远不能丧失他/她的道德和社会觉悟。

However great the will to achieve, and however great the demand to succeed, one should never abandon his/her moral and social consciousness.

41. 微软的创始人比尔・盖茨是成功的经典范例。

Bill Gates, founder of Microsoft, is a classic example of success.

Ask him to repair my watch/TV set.请他给我修一下手表/电视机。

The garage charged forty dollars to repair the car. 修车行修理这辆车收了四十美元。

repair还可作“弥补、补偿”讲。如：

How can I repair the damage I have caused?我怎样才能弥补我造成的损失？

I’d like to repair our differences .我想我们应该重归于好。

mend指将打破、撕碎或用坏之物修补完整，“缝补衣服”多用mend。如：

His clothes need mending.他的衣服该补了。

She mended the broken jar with cement. 她用水泥把破碎的缸补好了。

mend 还可意为“改正、纠正、治愈、使恢复健康”等。如：

The prisoner is mending his way.囚犯在改过自新。

It is never too late to mend.亡羊补牢，犹未为晚。

两者均是形容词，意思是“值得……的”，用法如下：

（1）worthy可以作定语，worth不能。例如：

（2）worth后面直接跟名词（多为表示钱或代价的名词），其作用相当于介词；worthy后面接名词时须与of连用（一般不接表示钱的名词）。例如：This second-hand book is worth 100 dollars.这本旧书值100美元。

His deed is worthy of praise.他的事迹值得赞扬。

（3）worth后面可直接跟动名词的主动结构；worthy后接动名词的被动结构，且须与of连用，worthy后也可接不定式的被动式。例如：

This book is worth reading./ This b

高三英语复习课件 篇13

非谓语动词有三种形式：不定式，动词ing形式(v-ing)及过去分词(ed分词)。

不定式的基本形式是由“to+ 动词原形”构成，其否定形式是not to do，不定式可以带自己的宾语或状语，构成不定式短语，没有人称和数的变化，但有时态和语态的变化，不定式在句中可作主语、表语、宾语、定语、状语、补足语，不作谓语。如：

Lucy asked him to turn up the radio.

To make a plan first is a good idea.

1. 动词不定式不失动词的特点，有时态和语态的变化，不定式有六种形式，以write为例：

(1)不定式的时态：

①不定式所表达的动作与谓语动词同时发生或是在谓语动词之后发生，不定式用一般式，如：

It seems that he knows this.

鯤e seems to know this.

I hope that I'll see you again.

鯥 hope to see you again.

②不定式所表达的动作与谓语动词同时发生，并强调动作正在进行的情景，或持续性，不定式用进行式，如：

He pretended that he was listening to English course when I came in.

鯤e pretended to be listening to English course when I came in.

I am very glad that I am working with you.

鯥 am very glad to be working with you.

③不定式的动作发生在谓语动词之前，不定式用完成式，如：

I am sorry that I have put you so much trouble.

鯥 am sorry to have put you so much trouble.

It seems that I have met you somewhere before.

鯥 seem to have met you somewhere before.

④如果强调不定式所表示的动作从过去某一时刻起一直持续到某一时刻，不定式用完成进行时，强调动作的持续性，不强调结果。如：

She seems to have been reading the novel for three hours.

The rain was said to have been falling for a week.

(2)不定式的语态：当不定式的逻辑主语与不定式是被动关系时，不定式一般用被动式。如：

This is the plan to be discussed at today's meeting.

The novel is said to have been translated into several languages.

Whether most countries can use natural energy in future remains to be seen.

(1)不定式作主语：

To say is one thing; to do is another.

To read novels is my hobby.

it形式主语常常代替作主语的不定式，而将不定式或不定式短语放在后面。

To talk with him is a great pleasure.

鯥t is great pleasure to talk with him.

To make electricity by building a dam across the sea is possible.

鯥t is possible to make electricity by building a dam across the sea.

注意：①To see is to believe. 主语和表语都是不定式，不能用it代替：It is to believe to see是错误的。

②To answer correctly is more important than to finish quickly. 而finish与finishing放在than后面都是不合适的，因为前面句子的主语是to answer，后面的主语也要是to finish, 保持than前后句子结构平行。

At that time his job was to write reports for the newspaper.

This suit doesn't seem to fit me.

The problems remain to be unsettled.

(3)不定式作宾语：在下列及物动词后，常跟不定式作宾语：want, need, hope, wish, expect, like, hate, try, manage, forget, remember, know, begin, start, intend, plan, mean, pretend, prefer, agree, refuse, learn等。

To keep the water clean, you need to get some under water plants.

I prefer to stay at home rather than go out.

They have decided to visit the nature park for the milu deer.

注意：不定式作宾语时，有时用“it”替换，it为形式宾语，而将真正的不定式作宾语后置，如：

I found to learn English well not easy.

鯥 found it not easy to learn English well.

I feel to help others my duty.

鯥 feel it my duty to help others.

Jim told me to give his best wishes to everyone here.

What caused you to change your mind?

在被动语态was considered后面，不定式为主语补足语接不定式作宾补和主补的动词常有:

ask, beg, cause, call n, help, force, allow, permit, advise, order, get, want, wish, tell

等。

(其中没有hope sb. to do, suggest sb. to do和agree sb. to do)

注意：①不定式作宾语补足语，在部分感官及使役动词后，用不带to的不定式作宾语，常用的动词有：let, make, have, see, watch, notice, observe, look at, listen to, feel等，help有无to都可以，如：

The teacher had us recite the text every day.

The boss made his men work all the night.

把上面句子变成被动语态后，不定式成为句子的主语补足语，需带to，即在被动语态中不定式一律带to，不存在省略问题。

注意：②在谓语动词think, consider, suppose, believe, imagine, prove, find等后面跟to be作宾补，不跟to do，但其中有些可跟to have done作宾补。如：

Imagine yourself(to be)in his place.

We found him(to be)honest.

suppose…to be/suppose…to have done.

I suppose him to be about fifty.

We suppose him to have stolen it.

(5)不定式作定语：不定式作定语，有时与前面被修饰的名词逻辑上有动宾关系，如果不定式是不及物动词或所修饰的名词是不定式的地点，工具等，不定式后面须有相应的介词，如：

I have a meeting to attend. (attend the meeting)

Pass me a piece of paper to write on. (write on the paper)

在time, place, way后面的不定式省略介词，如：

He had no money and no place to live.

其他不定式作定语情况，如：

I have no chance to go abroad.

They had never moment to rest.

There is a lot of work to do.

=There is a lot of work to be done.

There is no time to lose.

=There is no time to be lost.

但是在下列句子中，不定式主动与被动形式意义不同：

--Have you anything to wash?

--No, nothing. I plan to go shopping.

不定式动作的执行者是you. you wash something

--Have you anything to be washed?

--No, Thank you.

不定式动作的执行者不是you. 是省略了的(…to be washed)by me或by someone else.

I got up early in order to catch the 6∶30 train.

The boy ran all the way so as not to be late.

注意：so as to不能置于句首，in order to可以。

②作原因状语：

He smiled to think of his clever plan.

③在某些形容词后面作状语：

I am glad to see you.

You are sure to succeed.

④作结果状语：

第一, I hurried to the post office, only to find it closed. (出乎意料的结果)

He is too old to read.

The boy is too young to dress himself.

当不定式前的形容词为nervous, pleased, willing, delighted, happy, glad等时，too…to，“to…”可译作肯定，

They are too nervous to leave. 他们急于离开

I am only too pleased to help you.

We are never too old to learn. 活到老，学到老。

第三，形容词/副词enough to do sth.

He was quick enough to catch the ball.

The girl is old enough to go to school.

第四，so…as to/such…as to如此……以致于……

He was so angry that he was unable to speak.

He was so angry as to be unable to speak.

He was such a fool that he believed the cheat.

He was such a fool as to believe the cheat.

⑤不定式作方面状语，不定式作方面状语与句子的主语构成逻辑上的动宾关系，不定式多用主动结构，如果不定式为及物动词，后面不必再跟宾语，如果不定式为不及物动词，要用相应的介词，如：

The mountain is difficult to climb. (动宾关系：climb the mountain)

Lesson Two is easy to learn. (动宾关系：learn Lesson Two)

3. 不定式的逻辑主语：不定式的逻辑主语一般是句子的主语，如He seemed to be reading something, 当需要明确指出不定式动作的执行者时，用for/of sb. (sth. )to do sth. 表示，如：

(1)当作表语的形容词表达不定式的逻辑主语的品行，性格，性质时，要用of，常见的这类形容词有:

brave, careful, careless, kind, nice, good, honest, clever, wise, unwise, stupid, foolish, rude, cruel, silly, thoughtful, impolite, polite, right, wrong, 等。这时It+ be+ 形容词+ of sb. /sth. to do sth. 句型，等于sb. /sth. + be+ 形容词to do sth. , 如：

It is very kind of you to say so.

相当于You are very kind to say so.

It is clever of him to win the competition.

鯤e is clever to win the competition.

It+ be+ 形容词+ for sb. /sth. to do sth. 这一句型中的形容词大多为：

easy, important, usual, difficult, hard, possible, impossible, necessary等。这些词只能说明不定式行为的是与非，不能说明不定式的执行者，所以不等于sb. + be+ 形容词+ to do sth. ，如：

1)It is difficult for beginners to read the book.

不能说：Beginners are difficult to read.

但是第一类，即It+ be+ 形容词+ of sb. to do sth. 句型中的形容词，如right, impolite…等如果强调评论人用of，强调评论行为也可用for，应用情况如下：

(1)当sb. 为泛指时，形容词着重评论不定式行为本身，如：

It was not right for the south to break away from the Union.

(2)当不定式为被动语态时，不定式的执行者常常省略，因此形容词只用来评论不定式行为了。

It was unkind for you to be laughed at.

4. 带疑问词的不定式：动词不定式可以和疑问词what, which, how, where, when, whether等连用，构成不定式短语，如：

The question is when to start.

They haven't ageed on whether to build a factory here or not.

what to say.

I don't know what to write about.

how to do it.

注意：没有if to do和why to do.

I don't know why I should do it. (正)

5. 不定式省略“to”的情况：

(1)当and或or连接同一概念的不定式时，或者当它们之间的关系并列一致时，可将and或or后面的to省去，如：

I'd like to go and see a film.

He had to have a job or go hungry.

但是，有时为了表示对照，或加强语气，则不可以省去to，如：

It is easier to say than to do.

(2)不定式在一部分感官或使役动词后面作宾补省略to。

(3)不定式在but(除了……以外)，except后面的使用，如果but, except前有行为动词do, but, except后省去to，如：

They had nothing to do but wait for the doctor.

The whole night he did nothing except watch TV.

(4)在固定句型中：would rather do…than do…/prefer to do rather than do:

1)The bus was so crowded that I'd rather walk home than take a bus.

2)I prefer to play tennis rather than(play)basketball.

6. “to”代表整个不定式：有时为了避免重复，省去不定式后面的内容，保留到不定式符号to, 如果是to be，保留到be，如：

--Will you please give him a message when you see him?

--I'll be glad to.

--Would you like to go shopping with me?

有时为了强调，也可以不省略。

Do what he or she tell you to do.

动词-ing形式由动词原形+ ing构成。动词-ing形式起到名词、形容词和副词的作用，在句中可作主语、宾语、表语、状语和宾语补足语，但不能单独构成谓语，其构成形式如下，以do为例：

完成时态 having done having been done

Learning English is very important to me.

Having been widened, the road took on a different look.

随着-ing在句子中所做的成分不同，所用的时态和语态有不同的要求，关于-ing的时态和语态的详细使用，在下面ing所作的句子成分中讲述。

1. 动词-ing形式作主语：

Seeing is believing.

有时主语太长，可用it作形式主语，将真正主语放在后面。如：

It is fun swimming in a river or lake in summer.

It is dangerous playing/to play with fire.

但在口语中用动词-ing形式放在句首比不定式多。

Going shopping is a pleasant thing.

②在下列句型中习惯用-ing作主语，不用不定式：

It is no good doing.

It is useless only learning English grammar.

It is no good cutting down the forest.

③在there+ be+ no+ 主语结构中，必须用动词-ing作主语：

There is no telling what will happen in the future.

④主语和表语结构相同，对等。

Seeing is believing.

To see is to believe.

Would you mind my sitting here?

We suggest going out for a picnic on Sunday.

(2)在介词后：

We look forward to seeing you again.

(3)在worth, busy, feel like, look like等形容词后面：

China Daily is well worth reading.

The firefighters were busy putting out the big fire.

They look like winning the relay race.

Suddenly I feel like eating something.

动词-ing做主语或宾语时，一般情况下其逻辑主语为句子的主语，如果需要自己的逻辑主语时，要用物主代词或名词所有格+ 动词-ing，如：

His/Li Ping's coming late, made the teacher unhappy.

Would you mind my/me smoking here?

当动词-ing不在句首时，可用人称代词宾格，名词普通格代替，但逻辑主语为无生命的名词，或泛指时，用普通格，如：

We heard the noise of desks being opened and closed.

3. 不定式与动词-ing作宾语的比较：

(1)在下列一些动词后面常跟动词-ing作宾语，而不跟不定式：

admit, appreciate, advise, avoid, allow, consider, delay, dislike, enjoy, escape,

excuse, face, feel like, finish, fancy, forbid, forgive, imagine, include, keep, mention,

mind, miss, practice, resist, risk, suggest等。如：

He practices speaking English every day.

He admitted having broken the window.

I much appreciate your giving me the chance.

She dislikes doing housework.

He enjoys nothing but playing the computer.

(2)在下列一些动词后只跟不定式，不跟动词-ing作宾语：

want(想要)，hope, expect, wish, decide, would like, refuse, manage, pretend, demand,

offer, afford, plan, wonder, intend…等，如：

I am expecting to get a letter from my parents.

We are planning to build another research center.

I'd like to buy a new car made in the U. S. A.

(3)在下列一些动词后面跟不定式或动词-ing形式作宾语，意义不同，如：

I remember doing this exercise before.

我记得以前做过这个练习。

Remember to post the book for me.

记住帮我把那本书寄走。

We shall never forget hearing Jackson singing.

我们忘不了听杰克逊唱歌的情景。

Don't forget to give my regards to them.

I'll try to improve my pronunciation.

我要努力去纠正，提高我的发音。

Since no one answered the front door, why not try knocking at the back door?

既然前门没人答应，为什么不试试后门呢?

I suggest we stop working and have a rest.

我建议我们停下干活，休息一会儿。

They stopped to listen, but there was no more sound.

他们停下来，听一听，再没什么声音。

What do you mean to do with your old bicycle?

你打算如何处理你那辆旧自行车?

I won't wait if it means delaying a week or so.

如果这意味着要推迟一星期左右，那我就不等了。

(4)在love, like, hate, prefer后面跟不定式和动词-ing形式无多大区别，如：

Do you like to eat ice-cream?

I like traveling very much.

I like driving(do drive)fast cars.

(5)在start, begin后面，一般接不定式和动词-ing形式无多大区别，在下列情况下，多用不定式：

①自然界变化：

It started to rain.

Snow started to melt as spring came.

②心理活动，在understand, know, realize等词前面：

I began to understand my mother's feelings.

③begin, start本身为进行时：

Mother was starting to cook in the kitchen when I got home.

(6)在allow, advise, permit, forbid等动词后面，有名词或代词作宾语，用不定式做宾语补足语，如果没有宾语，直接用-ing形式，如：

1)We don't allow parking here.

2)The police don't allow people to park here.

3)He advised me to get an English pen friend.

4)I advise seeing more English films.

(7)need, require, want译作“需要”时，跟动词-ing作宾语，主动表示被动，相当于to be done，如：

The windows require cleaning.

The windows require to be cleaned.

The patient needs operating on at once.

The patient needs to be operated on.

The flowers want watering.

The flowers want to be watered.

(8)在一些固定表达中用动词-ing形式，不用不定式：

can't help doing, be worth doing, devote…to doing, look forward to doing, be/get/become used to doing, object to doing, thank…for doing, excuse…for doing等。

Einstein devoted his life to making a research in science.

I'm looking forward to getting your letter.

We are used to living in the countryside.

4. 动词-ing在句中作表语：

Our plan is setting up a new car factory.

My job is teaching/driving.

这类词作表语，起解释说明主语的作用，主表可颠倒：Teaching is my job. 转换成问句，用what提问：

--What's your job?

--My job is teaching.

--How is your job?

--It is interesting.

--How was your trip?

--It is tiring, but interesting.

5. 动词-ing作定语：

(1)表示被修饰名词的用途：

There are two reading rooms in our school library.

a reading room其含义是A room is used for reading.

The swimming pool in our school is nearly completed.

the swimming pool其含义是The pool is used for swimming.

(2)如果动词-ing形式作定语表示被修饰的名词发出的一个正在进行的动作或某种特征行为，这时被修饰的名词与动词-ing逻辑上有主谓关系，如果是主动关系用doing, 被动关系用done, 或being done表达，另外有时间要求：

第一种情况：主动关系，-ing形式与谓语动词同时进行，或经常发生，用doing，如：

Look at the dancing girl. She is one of my classmates.

Look at the girl who is dancing. ….

China is a developing country.

China is a country that is developing.

注意：①如果动词-ing形式表示的动作发生在谓语动词之前，一般不用having done作定语，而用定语从句表达，如：

The teacher criticized the boy having broken the window. (误)

The teacher criticized the boy who had broken the window. (正)

注意：②如果表达的是未来发生的动作，或含有情态概念，用不定式表达，如：

I have a meeting to attend today.

鯥 have a meeting that I will attend today.

Mary is the proper worker to do the job.

鯩ary is the proper worker who can do the job.

第二种情况：被动关系：动词-ing表达的动作与谓语动词同时发生，正在进行，用being done; 发生在谓语动词之前，完成了的动作用done；发生在谓语动词之后，未来的动作，用to be done. 如：

The bridge being built now is two kilometers long.

鯰he bridge that is being built now is two kilometers long.

The bridge built last year is two kilometers long.

鯰he bridge that was built last year is two kilometers long.

The bridge to be built next year will be two kilometers long.

鯰he bridge that will be built next year will be two kilometers long.

6. 动词-ing作宾语补足语和主语补足语：经常在see, hear, feel, watch, notice,

observe, find, get, look at, listen to, keep, leave, send, set, catch等一些动词后面用动词-ing作补语，其中宾语和宾语补足语在逻辑上有主谓关系，如果主谓关系是主动的，又表示动作在进行，或状态的持续，用doing; 如果主谓关系是被动的，又表示动作在进行，用being done，如：

I noticed them repairing the car.

鯳hen they were repairing the car, I noticed.

I noticed the car being repaired.

鯳hen the car was being repaired, I noticed.

如果宾语和宾补是主动关系，又表示动作的全过程，即完成或一般时态，宾补用不定式to do表达(在某些动词后面不定式不带to)；如果是被动关系，又表示动作的全过程，即完成时态用done表达，如：

I often notice them repair the car.

I noticed the car repaired.

如果把上述句子变成被动语态，宾语补足语就变成主语补足语了。

7. 动词-ing形式作状语：动词-ing形式作状语时，要求其逻辑主语必须是句子的主语，句子的主语与动词-ing形式逻辑上有主谓关系。如果主谓关系是主动的，用主动语态；-ing动作与谓语动词同时发生用一般式doing, 如果-ing动作发生在谓语动词之前，用完成式having done, 如：

Walking along the street, I met a friend of mine.

相当于When I was walking along the street, I met a friend of mine.

Having finished their work, they had a rest. 相当于After they had finished their work, they had a rest.

如果主谓关系是被动的，用被动语态；-ing动作与谓语动词同时发生，用done；如果-ing动作发生在谓语动词之前，已完成的动作，用被动语态的完成式having been done, 如：

Having been cleaned and decorated, our classroom took on a new look.

相当于After our classroom had been cleaned and decorated, our classroom took on a new look.

Well known for his expert advice, he was able to help many people.

相当于As he is well known for his expert advice, he was able to help many people.

注意：-ing形式做状语时，如果-ing形式需要自己的逻辑主语，人称代词用主格，名词用普通格，如：

Mother/She being ill, he had to stay home to look after her.

It being Sunday, the shops are crowded.

过去分词由动词+ ed构成，起到形容词和副词的作用，在句中可作状语、表语、定语和宾语补足语。过去分词的性质是被动，完成，但有时侧重程度，有时侧重被动，不及物动词变成的过去分词无被动的意义，过去分词形式由动词原形加词尾-ed构成，及部分不规则的词如：done, played.

①侧重程度：

boiling water 沸水 fallen leaves落叶

boiled water 凉开水 frozen chicken冷冻鸡

②侧重主、被动：

a broken glass, a dancing girl, a damaged house.

1. 过去分词的作用：

(1)过去分词作状语：同动词-ing形式作状语一样，过去分词的逻辑主语是句子的主语，如是被动关系，又与谓语动词同时发生，或无一定时间对比，用过去分词，如：

Seen from the top of the mountain, the lake looks like a mirror. (相当于The lake is seen)

相当于When the lake is seen from the top of the mountain it looks like a mirror.

Heated, water can turn into vapor.

相当于If it is heated, water can turn into vapor.

(2)过去分词作表语：

We are interested in science.

(3)过去分词作定语：过去分词作定语，有时间要求，发生在谓语动词之前，即完成的动作，用done，而不用having been done.

The bridge built last year is 2 kilometers long.

People invited to the party are most scientists.

(4)过去分词作宾补：

I noticed the car repaired.

2. 过去分词与动词-ing形式的区别：

(1)作表语和定语的区别：动词-ing形式表示事物对人造成的影响，事物是主动的，常译成令人……，使人……；过去分词表示人对事物的看法产生的心理反应，人是被动的，常译作：感到……如：

The news is surprising.

We are surprised at the news.

这类词很多，如：inspiring, inspired, astonishing, astonished, tiring, tired,

moving, moved, disappointing, disappointed, worrying, worried, encouraging, encouraged, …….

(2)作宾补的区别：宾语与宾补逻辑上有主谓关系，主动用动词-ing或不定式表达，被动用being done或done表达。

We found him standing outside the door.

He found the door locked.

(3)作状语的区别：用作状语的动词，与句子的主语逻辑上有主谓关系、主动用-ing形式，被动用过去分词。

The boy entered the room, followed by a dog.

相当于The boy entered the room and he was followed by a dog.

The boy entered the room, following his father.

相当于The boy entered the room and followed his father.

(4)-ing形式与ed分词都可以作状语，表示时间、条件、原因、伴随、结果、让步、程度，如：

Having brought her father back to England, Lucy helped him to get better. (时间)

After she had brought her father back to England, Lucy helped him to get better.

Disturbed by the noise, we had to finish the meeting early. (原因)

We had to finish the meeting early because we were disturbed by the noise.

Born a free man, he was now in chains. (让步)

Though he was born a free man, he was now in chains.

(If) bitten by a snake, you should send for help and not walk. (条件)

鯥f you are bitten by a snake, you should send for help and not walk.

The boy ran in, carrying a ball in his arm. (伴随)

鯰he boy ran in and carried a ball in his arm.

He dropped the plate, breaking it into pieces. (结果)

鯤e dropped the plate and broke it into pieces.

(5)-ing形式与ed分词的否定式，由not+ -ing构成：

Not knowing how to do it, I asked him for help.

高三英语复习课件 篇15

考研是一个极具选拔性和自学性的考试，复习考研也是个长期漫长的过程，鉴于此，在总结不同梯度考生基础阶段学习情况的基础上，为广大考生具体规划考研英语基础阶段的复习，以便为以后考研的成功打下良好的基础。

现在正值春季，正是考研英语基础复习阶段，具体每日的复习时间，需要根据自身情况而定。不管同学们基础好还是差，都必须保证每天花在英语复习上的时间为两小时以上。由于英语复习具备连贯性，所以定下计划持之以恒很重要。

具体到每一天来讲，早上晨读时间的40分钟当然属于英语，而另外，上午从10点30左右可以开始正式的英语复习，坚持一个半小时。在春季基础阶段，只要的复习内容应安排为词汇和语法，坚持每天两篇阅读，每日如此推进，日日不断。在每天进行新内容的同时，在第二天可以用一点时间(半小时内)翻阅一下昨天复习任务，然后再进行当天的复习计划。

很多学生将考研失利的原因归结为词汇量不够，因此耗费了大量时间和精力机械地背诵英文词汇。其实，考研和国外的IELTS、TOEFL考试相比，最大的区别就在于，考研有明确的考纲，有规定的词汇考查范围。考研英语复习过程中，考生完全不需要毫无目的地记忆大量词汇，只需要将大纲规定的考研词汇研究透彻即可。

英语基础阶段以记忆词汇为主。在记单词的过程中可以采用以下五种记忆方法：形象记忆法、联想记忆法、例句记忆法、循环记忆法和同素记忆法。这五种方法中，联想记忆法和循环记忆法这两种方法比较好，具体的方法运用在我们的课程上有详细讲解。

语法是很多同学的弱项环节。语法弱意味着不能根据有序单词表达出的意思做出正确的反映，会造成信息链的断裂，而只有当你分清了句子的结构之后，才能将阅读、作文等内容和题意理解得更加明白。在考卷的阅读部分有四大难点：单词、长句子、非谓语、介词。这四点，其实有三点都涉及到了语法。因此加强语法的掌握力度可以有效拉高英语得分。

现在考研英语对阅读的考查越来越多，这也要求我们进一步的提高阅读能力。虽然考研的阅读理解有一定的规律可循，但是这些规律也在逐年的淡化。这几年反技巧的出题趋势越来越明显，考试越来越重视考生的真正阅读分析能力。所以，的考研考生们一定要提前打好基础，每天除了背单词、巩固语法知识外，还要阅读一定量的英语报刊。据了解，考研的阅读理解很多都是摘自国外的一些著名的报纸，如比如《发现》、《商业周刊》、《探索》、《经济学家》、《新闻周刊》等专业型极高的刊评等等。如果能找来的话，这些都是很好的阅读材料。而且还要刻意训练自己快速阅读的能力。考研英语的阅读量越来越大，里面不但有很多考查全文的主旨题，还有很多的细节题和作者态度题，这些内容的提炼都要我们在平时的阅读中渐渐地培养。

英语并不可怕，可怕的是同学们没有持之以恒的毅力，希望大家从现在开始认真备考，预祝大家在明年春天有一份喜悦的收获!

Hello, everyone,

Now I’ll tell you something about our research project The World Food

Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social uest in some areas. But who is responsible for the current world food crisisFirst, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problemOn one hand, we should focus on the environmental protection and improve the ecology. On the

other hand, strict measures should be taken to protect farmland. Of course, to

build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.As for me, I will call on the people around me to live thriftily. And for the

moment, I think, we should study hard to develop science and help solve the food shortage in the future.

高三英语专题复习教案――基础写作    教学重点：如何审题；如何进行信息整合；上下文的承接。   教学难点：写作思路及方法的培养   教学方法：讲练结合，精讲多练，引导学生体会与模仿。   教学目标：学生进一步熟悉基础写作的特征和基本要求，培养正确的写作思路及方法，掌握常用的写作模式和句型。消除对写作的恐惧心理，培养写作兴趣。    一、基础写作题的特点 高考设置基础写作题的目的是要检测考生最基础的书面语言表达能力，如用词的合理性、句子结构的复杂度、语法运用的正确性、信息内容的完整性、句子之间的连贯性等。因此，基础写作题与往年的书面表达依然会有很多相似点，但也会出现一些新的特点。   1．写作题材贴近考生的学习和生活。历年来高考作文题的题材都非常贴近考生的学习和生活，如校园活动、校外见闻、交友、旅游、以及与考生有关的话题讨论等。可以预料明年高考写作题的题材还会在这些范围内，并为所有考生所熟悉。 2．写作的题材主要是故事性描述和应用文。历年的基础写作题的题材也会与往年书面表达相似，主要有故事性描写和应用文写作两大类。命题形式可能是看图写故事、看图表说明、根据表格信息完成一封短信或一份通知这类的应用文等。 3．内容呈现的方式具有半封闭性。作文试题逐步走向开放将是大势所趋。但是，基础写作题还只能是半封闭的，其特点是写作的内容是被规定了的，考生必须将文章所规定的信息点完整、全面地表达出来，但对于语言表达的方式、信息组织的先后秩序、需要补充哪些必要的信息等，考试又有一定的自主构思空间。 4．用5句话表达。这是基础写作题与往年书面表达题最显著的不同点。往年是规定字数（100词左右），句子的数量不作规定，所以很多考生为了不犯句法错误总是使用一些简单句。而历年的基础写作只能用5句话来表达题目所给的全部信息点，但所给的信息点与往年的书面表达相比并不会减少，所以，用5个简单句很难完成任务，必须使用复合句或并列句来综合多个信息点，而且还要照顾句子之间的衔接和语意上的连贯。从只一点来说，基础写作题对考试运用语言能力的要求大大提高了。     二、基础写作题提出的新要求  1．信息组织能力。信息组织能力包括信息归类、信息排列和信息表达三个环节。对于题目所提供的各种信息点，考生首先需要依照一定的标准将信息进行归类，并初步计划将哪些信息放到同一个句子中；其次是将信息进行合理的排列，排列必须依照一定的标准，如时间顺序、空间顺序、因果关系、递进关系等；第三是选择表达的秩序，确定句子之间的先后顺序，这既要考虑语句上能否衔接，还要考虑语意上的连贯。在组织信息的过程中，还要对某些信息进行必要的增删，使文章意思连贯、语言畅谈、逻辑严密。 2．运用复杂句子的能力。在整理和归类信息点之后，就需要正确地使用比较复杂的句子，综合的表达信息。复杂句子主要有三类： 第一类是复合句或含有非谓语动词、介词短语的复杂句。复合句主要有三类：含有名词性从句的复合句，含有状语从句的复合句，含有定语从句的复合句。 第二类是并列句或带有并列成分的复杂句。连接并列句或并列成分的并列连词主要有四类：表示意义引申的并列连词，如and，both… and，not only…but also，and… as well，not… nor，neither… nor等；表示选择的并列连词，如or，whether… or，either… or等；表示转折或对比的并列连词，如but，while，whereas，only等；表示因果关系的for。此外，therefore，besides，however，nevertheless，moreover，furthermore，what’s more，in addition，on the contrary，after all等连接性状语也可以在句子之间起连接作用，表示分句之间的并列关系。 第三类是一些特殊句型，如使用强调句、倒装句、含有with复合结构的句子、there be开头的句子、以形式主语it 开头的句子等。 正确使用各种句型，不仅能够完成题目所要求的任务，还能使文章的句式变得丰富、行文更加流畅、中心和主旨更加突出。     三、基础写作题的备考策略 在基础写作的备考过程中，一方面要重视养成一些良好的写作习惯，如认真审题、巧妙构思、常写草稿、工整书写、仔细核对等好习惯，另一方面在组织信息和训练复杂句子结构方面要多下工夫。下面以“广东省普通高等学校招生全国统一考试广东省英语科考试说明”中的样题为例，探讨如何备考基础写作题。 第一节：基础写作（共1小题，满分15分） 假设你最近参加了由某电视台举办的中考生英语演讲比赛并获奖，该台准备组织获奖者去北京参加一次英语夏令营活动，下表是这次活动的时间安排和活动内容。 活动时间 7月15日 ― 22日或8月15日― 22日 活动内容 参加英语角  学唱英语歌曲  听英语讲座  表演英语短剧 看英语电影  教外宾学中文   【写作内容】   电视台就活动时间和活动内容征求你的意见。请按照以下要求用英语以书信形式给予答复。 1．选择适合你的时间并说明理由； 2．解释你只能参加其中的两项活动（听英语讲座和教外宾学中文），虽然你认为所以的活动都很有意义； 3．说明你选择的理由：听英语讲座了解英美文化的信息；教外宾学中文因为北京奥运会让越来越多的外宾想了解中国。 【写作要求】 1．必须使用5个句子表达全部内容 2．信的开头和结尾已给出。 Dear Sir or Madame, I’m glad to be invited to the English summer camp. ……. Thank you very much.   Yours truly, Li Ping   【评分标准】   语       言 7 ― 8 具有很好的语言运用能力；语法和句子结构准确性高，词汇方面使用较好，只有少许错误。 5 ― 6 具有较好的语言运用能力；语法和句子结构准确性较好，有一些语法结构或词汇方面的错误，但不影响理解。 3 ― 4 语言运用能力一般；语法和句子结构基本准确，语法结构或词汇方面的错误不影响理解。 1 ― 2 语言运用能力较差；语法和句子结构基本不正确，语法结构或词汇方面的错误较多，而且影响了对句子意义的理解。 0 语言运用能力很差；语法、句子结构、词汇错误很多，句子意义无法理解。 备注 每多写或少写一个句子，扣1分。 内     容 5 包括了所有信息内容 4 包括了大部分信息内容 3 包括了基本信息内容 2 包括了小部分信息内容 1 包括了少许信息内容 0 没有包括所提供的信息内容 连   贯 2 内容连贯，而且结构紧凑 1．5 内容连贯性比较好，而且结构比较紧凑 1 内容连贯性教差，而且结构不够紧凑 0 内容缺乏连贯性，而且结构松散 备注 文不对题，给0分   由此我们可以看出，信息点的数量与往年的书面表达题相比并没有减少，要想用5个句子把所有的信息都表达出来，考生必须从以下三个方面进行备考：   1．养成重视审题的习惯。虽然基础写作题是半封闭性的，但审题仍然十分重要。现以样题为例，谈谈如何审题：   思考的问题 样题分析 要写的文章主题是什么？ Topic 参加夏令营 为什么要写这篇文章？ Purpose 电视台邀请参加夏令营，写信回复。 要写文章的信息点有哪些？information items 选择的时间，参加活动的内容，解释什么 怎样安排信息点的'逻辑顺序？ order 说明要参加的活动并解释原因→说明要参加的时间并解释原因。 动作是什么时候发生的（时态）？when 夏令营还没有开始，文章主要用一般将来时     2．提高组织信息的能力。组织信息的过程包括信息分类、信息排列、和信息表达三个环节。这些步骤看起来好像很繁琐，但对于中下成绩的考生来说，一步一步地思考这些问题是很有必要的。现以样题为例，说明该怎样组织信息。   信 息 分 类 时间信息：两个时间段 内容信息：6项活动 选择信息：其中的两个活动及其理由 信 息 安 排 夏令营的内容信息点安排：可以将自己要参加的两项活动放在前面，其它信息点可以略写。 作者的选择信息排列：依照自己所参加的活动顺序逐项表述，紧接着给出选择的理由。 信 息 表 达 结合已经给出的头和尾，写作的顺序安排如下：很高兴被邀请（已给出）― 感谢安排这么多的活动 ― 说明活动的意义 ― 表达自己只能参加两项活动的遗憾和原因 ― 说明参加的活动内容及原因（两项活动用一句话）― 说明自己选择的时间及原因     3．夯实基础，掌握基本的句子结构及其用法。对于大多数考生来说，用词不准和句子结构错误是写作失分的“罪魁祸首”。夯实基础、掌握基本的句子结构及其用法是基础写作备考的主要任务，完成这项任务可以分步骤进行：   教学内容与过程： Step one: Greetings and dictation Step two: 讲练结合，并就学生作文较常出现的错误进行点评，讲评过程注意把握好学生作文中的常见的非智力因素方面的失分。 Step three: 就学生作文中出现的常见错误进行适当的点评。 Dear Sir or Madam, I’m glad to be invited to the English summer camp. ① Thank you very much for arranging so many activities, such as English corner, English lectures, English films, English songs, English plays and helping foreigners learn Chinese. ② I am sure all the activities will do a lot of good to us students. ③ But it is a pity that I can only take part in two of them, because I will have to spend some time in doing my research project. ④ I would like to listen to the lectures, by which I will learn some about western culture, and help

高三英语复习课件 篇4

1.利用课文的词、句复习，训练学生的组句能力。从词和句入手，将每个单元课文的词和句与基础写作结合起来，是培养和提高学生的英语能力的有效途径。这不仅能帮助提高学生记忆和灵活应用词汇的能力，而且还有助于训练学生语句表达的正确性。

(1)归纳词汇和句型，帮助学生建立对词、句使用的感性认识。写作是一种语言的输出形式，只有大量的语言输入，语言输出才有可能;只有积累了一定的感受和大量的语言素材，写作才有可能进行。为了帮助学生记忆课文中的单词和短语，达到积累语言素材，掌握基本语法知识与语句结构的目的，教师可以从训练学生归纳每个单元课文中出现的重要词汇、短语和常用句型入手，使学生对句型结构的认识更加清楚，并对词、句的使用语境形成感性的认识。

(2)操练词汇和句型，训练学生的记忆和使用词、句的能力。为了使学生掌握和应用课文中所学词汇和句型，教师应为学生创设多层次的练习活动，拓宽写作的.训练途径。教师可采用将学生从课文中归纳的词汇、句型进行词类转换、习惯用法、句型转换、完型填空、写短文等形式的训练，帮助提高学生的记忆和使用词、句的能力。

二、借鉴课文词、句进行仿写。

通过提供情景让学生模仿造句，不仅可以降低写作难度，而且可以增加学生写作的兴趣、自信和成就感，使学生的遣词造句的能力在实践中得到提升。

三、借鉴课文句型，训练写作多种表达与技巧，拓展学生思维。

教师在教学实践中会发现，学生在基础写作中往往出现句式雷同、语句呆板、行文单一等现象，缺乏用5个句子有效表达和传输信息的能力。因此，教师就有必要继续进一步加强句子多样化表达、句子转换替代、句子合并等训练，教会学生使用不同的短语、句型结构表达同一的意义;同时，还让学生明白写作的逻辑原则:一个句子表达的信息量越多，而且使用的句子越精练、清楚，那么句意表达和传输信息就越有效。

四、利用课文体裁，训练学生谋篇布局的能力。

教师会发现高三学生在写作中存在的另一个问题是层次不清、结构散乱以及逻辑性不强，这是因为学生缺乏谋篇布局的能力。针对这方面问题，教师可以在教学中利用课文的体裁进行文章结构方面的训练以及进行句子、段落间的连接训练。

高三英语复习课件 篇5

1.now that; due to; because of; owing to; since; as

now that作“既然”讲时，相当于since。now that中的that 可省去。如：Now(that)you are well again, you can travel, 你既然恢复了健康，就能够旅行了。

due to作 “起因于、归功于”时，常作表语或跟在名词后，如：

Mistakes due to carelessness may have serious results.粗枝大叶造成的错误可能带来严重后果。

The team’s success was largely due to her efforts.该队的成功在很大程度上是由于她的努力。

because of“由于、因为”，在句中作状语或表语。如：

Lincoln is admired because of his good leadership.林肯由于其出色的领导而受到人们的赞赏。

Where does this stream join the Changjiang River?这条河和长江在哪里会合？

unite意为“联合”，指两种以上的事物结合为一体，有合二为一的意味，强调结合后的统一性。

The two companies will unite into one.这两家公司将合并成一家。

The whole family united to help him.全家齐心协力帮助他。

repair指将受损、故障、用旧之物修理好，如用于修补机械方面的东西多用repair。如：

It is never too late to mend.亡羊补牢，犹未为晚。

两者均是形容词，意思是“值得……的”，用法如下：

（1）worthy可以作定语，worth不能。例如：

（2）worth后面直接跟名词（多为表示钱或代价的名词），其作用相当于介词；worthy后面接名词时须与of连用（一般不接表示钱的名词）。例如：This second-hand book is worth 100 dollars.这本旧书值100美元。

His deed is worthy of praise.他的事迹值得赞扬。

（3）worth后面可直接跟动名词的主动结构；worthy后接动名词的被动结构，且须与of连用，worthy后也可接不定式的被动式。例如：

This book is worth reading./ This b

SeniorⅢ Unit4 Green World Integrating Skills

一、 教学思路：

1 . 高考阅读理解的特点是所选材料题材多样化，记叙文、说明文、议论文、应用文等特色鲜明，内容涉及科普、社会、文化、政治、经济、历史等各个方面，文章阅读量大。主要考查考生综合运用所学知识获取信息、整理信息、理解信息以及处理信息的能力。测试的主要要求是：

①．掌握所读材料的主旨和大意，以及用以说明主旨和大意的事实和细节。

②. 既能理解具体的事实，也能理解抽象的概念。

③．既能理解字面的意思，也能理解深层的含义，包括作者的态度、意图等。

④．既能理解某句，某段的含义，也能理解全篇的逻辑关系，并据此进行推理和判断。

⑤．既能根据所提供的信息去理解，也能结合中学生应有的常识去理解。

根据这五项要求，我们可将阅读理解题归纳为以下几种题型：细节理解题，词句理解题，主题、主旨题，猜测词义题，推理判断题。

2． 高考的要求就是我们平时课堂教学训练的方向。高中英语课文内容包罗万象、题材广泛、体裁各样、语言知识丰富。除了要让学生掌握英语基础知识外，我们更可以利用课文的教学，精心设计问题，按照高考的要求有针对性地对学生进行问题解答训练，提高学生的阅读速度，培养学生的阅读理解能力。

二、教材分析：

本课是第四单元综合技能部分的课文，介绍了达尔文和其他科学家关于物种的研究和他们的成果。内容涉及到遗传学和基因学的知识，文章有一定难度。是本单元主题绿色世界的一个延伸，又为本单元紧接的写作训练作铺垫。

三、 教学法分析：

1、 问题教学法。精心设计问题，以问题为主线，在提出问题和解决问题过程中，培养学生阅读理解能力。设疑与提问是英语教学课堂调控的常规武器。它是促进师生之间信息交流反馈，推动教学流程迅速向前拓展的重要契机。

2、 “自上而下的模式”。 这是哥德曼（Goodman）提出的阅读理论模式。按这个模式，阅读者在阅读过程中不是逐字、逐句地去理解，而是结合自己的预测，在文章中找出有关的信息，来验证自己的预测。由于强调整体篇章理解，在阅读时采取跳跃式搜索、猜测等方法，所以有利于培养学生快速阅读理解能力。

四、 学生分析：

两个班学生基础有限，学习英语有兴趣但没功底。成绩差距较大。尤其对文章缺乏整体感知能力，对深层次问题无从下手，信息的获取和分析能力都较弱。

五、 教学目标及重难点：

由于本课教学以发展学生解决问题能力为主，不设知识目标与情感目标。能力目标亦即重难点：

1、 培养学生快速获取信息解决表层次问题的能力；

2、 培养学生深层思考，培养信息重组、推理分析判断能力。

七、 教学步骤：

1． Lead in: Show two pictures on the blackboard:

2. What are differences between them? Why?

Maybe we can find the answer to this question in our text.

2. Fast reading: Open the book, read through the text. Find out:

How many scientist are mentioned in the text?

S：There are three. They are:

Charles Darwin Gregor Mendel Gote Turesson

T：So how many parts can we divide the text? (划分段落，整体感知)

T: Could you find the main idea of each paragraph?

学生做完这个步骤后，我总结并用幻灯打出：

Part I (Pa1-3): Darwin and his research.

Part II (Pa4-5): Mendel and his experiment.

Part III (Pa6): Turesson and his study

Part IV (Pa7): the importance and significance of the research of the three

3. Careful reading: (1) Show a slide of a table, ask the student to read the passage again, fill in the following:

Scientists Research/experiment Result

(用图表的形式处理文章信息，既避免问题提出的形式重复，又方便学生整体快速把握文章的重点段落)

(2) (完成以上整体表层次训练后，通过幻灯片打出以下问题，再细部理解文章)

Finish the following exercises:

1. What led to his writing of the famous book On the Origin of species?

A. The study of physics, chemistry, and botany.

B. What he had observed on the voyage.

C. His expedition on the Beagle to the Galapagos.

2. Why did the wildlife of the Galapagos Isles deserve special attention?

3. What does “these” in “of these” in Para 2 mean?

4. “those” in Para 2 Line 4 refers to ________

A. the different islands B. the life forms C. differences D. the species

5. What was the purpose of Mendel’s experiments?

A. His purpose was based on his love nature.

B. His purpose was to support the ideas concerning the influence of

environment upon plants.

C. His purpose was based on the influence of environment upon plants.

6. The research by Darwin, Mendel and Turesson shows that______

A. genetics is more important than the environment to plants

B. genetics is less important than the environment to plants

C. both genetics and the environment are important to plants

D. neither genetics nor the environment is important to plants

7．What was Darwin’s new theory according to the text?

(以上问题有深有浅，既有符合高考的细节理解题(如第1题)，词句理解题(如第3、4题)，推理判断题(如第7题)，设计时更因答案的不唯一性(如第1题BC均正确)，增加了题目的灵活性和难度。在解答过程中特别强调：

第1题：选项在文章中都有出现，但未必就是答案。题目不难，容易上当。

第3题：培养学生联系上下文准确把握词句意义，这道题目难度不大，但出奇的是学生正确率并不高。

第4题：这与第3道题是一样的，但难度较大。这两道题的题型在高考中经常出现。

第7题：这道题很难。考查学生对文章事实的延伸理解，训练学生根据文章事实作出推理判断的能力。是一道深层次理解推理判断题。)

(3) Answer the last question:

What do you think is the relationship between the title “Wildlife and Garden

Roses” and the text?

（这个问题非常难！也是整节课的精华部分，解决分析这个问题我花了十多分钟时间。问标题和文章的关系并不新鲜，关键是这个标题用得非常好，借此我分析了高考中常考的一类题目：给文章找标题。完成这个问题既是对整篇文章的概括理解，又是对高考常考题型解题技巧的一次传授。）

Wildlife shows the influence of environment while Garden of Roses shows the

science of genetics.

八、 Homework:

1. Read the text.

2. Learn the language points by yourselves

Charles Darwin Gregor Mendel Gote Turesson

the influence if the environment the science of genetics

1、 高中英语课文应该怎么教？又要教什么？这一直让我思考。我想很多英语老师对课文当中的语言知识是绝对不会漏的，但是不是通过课文的教学培养和训练学生的阅读技巧和阅读能力了呢？也许因为时间，也许因为方法，可能落实不太好。尤其在高三，课文没有出现新的语法点，怎样通过课文的教学达到这一目的，以利学生高考，更值得我们思考。

2、提问是一门艺术，也是一种教学方法。苏联教育界倡导的一种教学方法就叫问题教学法，已成为有世界影响的教学方法之一。问题是思维的向导，合适的课堂提问，往往能把学生带入一个奇妙的问题世界，使学生积极思考问题，寻求解决问题的途径和答案，从而培养学生分析问题和解决问题的能力。布鲁斯乔伊斯说过：“教会学生独立思考，我们就给了他们自我教育的能力。” 课文教学未必要设很多的问题，但要典型；其次问题分析要透彻，分析一个问题就要教会学生一种技巧或是让学生有一次能力的锻炼。问题设计是否巧妙，问题分析是否精当，就是判断这种课好坏的依据。

高三英语复习课件 篇7

英语阅读中，有时作者并未把意图说出来，而是要求阅读者根据字面意思，通过语篇逻辑关系，研究细节的暗示，推敲作者的态度，理解文章的寓义，这就是判断推理题。判断推理题在阅读测试中属于难题。因此，考生应在理解全文的基础上，从文章本身所提供的信息出发，运用逻辑思维，哲学原理，并借助一定的常识进行分析，推理，判断。

推理题经常使用的提问方式有：

It can be inferred/ concluded that___________.

Which of the following conclusions can we draw according to the passage?

In which of the following publication would this passage most likely be printed?

The passage implies, but doesn't directly state that___________.

The writer suggests that___________.

What's the author's attitude toward___________?

The writer probably feels that___________.

The author uses the examples of... to show that___________.

判断推理是一种创造性的思维活动，但它并非无章可循。

推理判断题要在阅读理解整体语篇的基础上，掌握文章的真正内涵。①要吃透文章的字面意思，从字里行间捕捉有用的提示和线索，这是推理的前提和基础；②要对文字的表面信息进行挖掘加工，由表入里，由浅入深，从具体到抽象，从特殊到一般，通过分析、综合、判断等，进行深层处理，符合逻辑地推理。不能就是论事，断章取义，以偏概全。③要忠实于原文，以文章提供的事实和线索为依据。立足已知，推断未知。立足现在，预测未来。不能主观臆想，凭空想象，随意揣测，更不能以自己的观点代替作者的观点；④要把握句、段之间的逻辑关系，了解语篇的结构。要体会文章的基调，揣摸作者的态度，摸准逻辑发展的方向，悟出作者的弦外之音。

要求考生根据语篇关系，推断具体细节，如时间、地点、人物关系、人物身份、事件等。一般可根据短文提供的信息，或者借助生活常识进行推理判断。

A visitor visits an island where two tribes live. One tribe always tells the truth and the other always lies. The truth瞭ellers live on the western side of the island, and those who lie live on the eastern side. The visitor wants to determine whether the native beside him is a truth瞭eller or not by asking only one question. He asks the native,“Go and ask the native in the distance which side of the island he lives on.” When the messenger returns, he says, “He said he lives on the western side of the island.”

Is the messenger a truth瞭eller or not? How can the visitor be sure?

1. According to the messenger's answer, the visitor can conclude that_______________

A. The messenger lives on the western side of the island because he tells the truth.

B. the messenger lives on the eastern side of the island because his answer may be a lie.

C. it's hard to determine whether the messenger is a truth teller or not.

D. the messenger probably lives in the western side of the island because his answer may be true.

2. The native in the distance says he lives on the western side of the island. According to his answer, which conclusion of the following is wrong?

A. He may live on the eastern side of the island.

B. He may live on the western side of the island.

C. He may be telling the truth.

D. He can't be telling the truth.

【解析】 第1题是推测有关信使（近处的当地人）的情况的。我们知道，讲真话的部落住在岛的西部，撒谎的部落住在岛的东部。这个信使去问远方的当地人住在岛的哪一边（东部还是西部）。远方的当地人只能有两种情况，要么住在岛的西部，要么住在岛的东部。如果他住在岛的西部，他就是一个讲真话的人，他就会如实回答他住在西部。如果他住在岛的东部，他就是一个撒谎的人。他本来住在东部，但在回答时，必须要说谎，他只能回答他住在西部。所以远方的当地人不管是住在东部还是西部，他的回答只有一个：“我住在西部”。如果信使告诉参观者远方的当地人住在西部，信使无疑是说了真话，那么信使一定是住在岛的西部。反之，如果信使告诉参观者远方的当地人住在东部，那么信使就说了假话，信使肯定住在东部。故此题答案是A。

第2题是推测远方的当地人的情况的。从短文提供的信息来看，我们无法判定远方的当地是住在岛的东部还是岛的西部，两种情况都是可能存在的。此题要注意情态动词的语气。A.“他可能住在岛的西部”;B.“他可能住在岛的东部”;C.“他可能讲了真话”。上述A、B、C三种情况都是可能的。D.“他不可能讲真话”，语气太绝对。推测错误。故答案为D。

要求考生根据已知结果推测导致结果的可能原因。考生要准确掌握文章的内涵，理解文章的真正含义。

When the young waitress near my house started saying hello to me every day, I was very happy. She was at least fifteen years younger than I. One day she signedme to come near. When I walked over, she asked,“Are you single?“ “Why, yes.” I answered, smiling at her happily.

“So is my mother.“ she said, “Would you like to meet her?”

1. The writer talked about the waitress' age because he thought___________.

A. she was young B. it a pleasure to make friends with her

C. she was beautiful D. it strange for her to fall in love withhim

2. The waitress said hello to the writer every day because___________.

A. she lived near his house B. he often went to visit her mother

C. she wanted to be friendly with him D. she loved him very much

【解析】 这是两道推测原因的题目。女服务员每天向作者示好，作者产生误解，以为女孩对他有意。考虑到他们年龄相差悬殊，作者认为女孩爱上他有点奇怪。故第1题答案是D。女孩问作者是否单身，并提到她母亲也是单身，并邀请他与她母亲见面，可见，女孩每天向他问好，目的是想取得他的好感，进而搓和他和她母亲。第2题答案是C。

The entertainment profession or “show business“ attracts many young people. Unfortunately, only very few can hope to become famous and successful. Talent is not enough, because show business is as competitive as any other business .Without a good manager ,a performer can never hope to succeed .Fashion is important in this business, too. The best tailor in the world will never be a success if he makes old瞗ashioned clothes. In exactly the same way, a performer must changehis “act” in order to follow the taste of the moment. This is true for actors, dancers and comedians ,but perhaps most of all singers.

“Pop“ stands for “popular” and a pop singer has to work very hard to become popular .He must either give the public what they already want, or he must find a new way of singing that will attract their attention. Even when he has succeeded, and his records are sold everywhere, he can not relax. Then he must work harder than ever because there are always younger singers trying to become famous and to steal some of the popularity. The life of a successful pop singer is not at all easy. He can only relax when he is alone, because everything he does is watched and reported in the special newspaper written for the “fans“.The fans are the most important people in the world for the singers. They buy his records, they go to his concerts and they make him rich and famous. But they can be very annoying, too. Sometimes their enthusiasm get so hysterical that they do anything to get a“souvenir”（纪念品）. They steal handkerchiefs, they tear off buttons, and they even cut off pieces of the unfortunate singer's hair. Many singers have been forced to hide. A pop singer has to spend a lot of money on clothes, because he must always look smart or at any rate different. He must have a luxurious car. And - most important - he must always keep smiling for the benefit of his public .

1. Why must a pop singer have a good manager?___________.

A. To protect him from his fans B. To look after his business interests

C. To help him to change his “act“ D .So that he can relax

2. Why must a pop singer work even harder when he has become famous?___________

A. Because he wants to attract the attention of the public

B. Because he wants to sell more records

C. Because he wants to become popular

D. Because he wants to stay popular

【解析】 1. 答案为B。因果推断题。根据Talent is not enough, because show business is as competitive as any other business. Without a good manager, a performer can never hope to succeed .我们可以知道，正因为这个行业竞争激烈，所以表演者需要一个好的经纪人。帮助演员策划和安排商业表演活动，协助他的演艺事业的发展。故B项正确。

2. 答案为D。因果推断题。Then he must work harder than ever because there are always younger singers trying to become famous and to steal some of the popularity. 一个成名演员要更加努力地工作，直接原因文中已有论述，即，表演行业是个竞争十分激烈的行业，新人不断涌现，对成名演员造成很大的压力。那么间接原因是什么？通过前面的分析我们可以推断出成名演员更加买力地工作，是因为他要保持他的名气，延长他的艺术生命。

Once Napoleon stayed in a small inn. The next morning, he went to thank the ﹊nnkeeper.ァ癥ou, have served me well, innkeeper, ” said Napoleon. “I wish to reward you. Tell me what you want.“

“Sir, we want nothing, ” said the innkeeper.“But will you tell us something?“ァ癢hat is it?” Napoleon asked.

“We have heard a story.“ said the innkeeper, “that once during the war, a small village was taken by the Russians. You happened to be in the village. You hid while they looked for you. Will you tell us how you felt when they were looking for you?” Napoleon looked very angry. He called in two of his soldiers. Then he pointed to the door. The soldiers took the innkeeper and his wife out into the yard.

At the end of the yard was a wall. The innkeeper and his wife were led to the wall. The soldiers tied the hands of the innkeeper and his wife. Napoleon watched, saying nothing.

“Please, sir.“ begged the innkeeper, “Don't kill us! we meant nothing!” The soldiers moved back. The innkeeper saw them raising their guns. Then Napoleon called: “Ready! Aim!“ The wife screamed. “Stop!” said Napoleon. He went to the innkeeper, “Now, you know the answer to the question you asked me just now, don't you?“

1. Why did the innkeeper ask Napoleon to tell him how Napoleon felt when he was being looked for?

A. He wanted to know the difference between a general and an ordinary people.

B. He looked down upon Napoleon, for he thought a great man shouldn't be defeated.

C. He showed his玸ympathy(同情) to Napoleon in time of danger.

D. He was interested in other's failure, especially Napoleon's.

2. Why did Napoleon ordered his men to tie the couple?

A. Because he wanted to teach the innkeeper a good lesson for bothering him.

B. Because he wanted to kill the couple to get rid of his anger.

C. Because he wanted to show that he was so admiring a general that nobody could upset him.

D. Because he wanted to made the innkeeper know that a general like him had the same feeling as the ordinary people in face of danger.

【解析】 1. 此题为因果推断题。根据“Sir, we want nothing, ” said the innkeeper.“But will you tell us something?“ 可以看出来，这个店老板问拿破仑这个问题是出于好奇。他想知道作为将军的拿破仑与普通人到底有什么区别。故答案为A。

2. 因果推断题。从最后一句话“Now, you know the answer to the question you asked me just now, don't you?” 可以看出拿破仑并不想杀这个店老板，他这样做的目的是想让他体验一下他当时的感受。故可推出面对危险像拿破仑这样的将军与普通人没有什么两样。故答案为D。

Three men were discussing how to玠onate(捐献) money to God. At first they couldn't agree with each other, then they each told his own idea.

The first man said: “Let's draw a small circle on the ground and throw coins to the ground. The money out of the circle belongs to God.”

The second man added, “We will donate the coins inside the circle to God because God is in our hearts.“

Imagine that the genome(基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.

1. The real purpose of the author's comparison of the genome to a book is___________.

A. to focus on the differences between the two

B. to lay emphasis on the similarities between the two

C. to simplify the concept of the human genome

D. to give an exact description of the human genome

【解析】 “基因组”是一个非常抽象难懂的科学术语。作者在这里把“基因组”比作一本书，使一般读者能通俗形象地了解“基因组”的概念。故答案为C。

Beldon and Canfield are two seashore towns, not far apart. Both towns have many hotels, and in summer the hotels are full of holiday瞞akers and othertourists(观光者).

Last August there was a fire at the Seabreeze Hotel in Beldon. The next day, this news appeared on page two of the town's newspaper. The Beldon Post: FIRE AT SEABREEZE

Late last night firemen hurried to the Seabreeze Hotel and quickly put out a small fire in a bedroom. The hotel manager said that a cigarette started the fire. We say again to all our visitors： “Please don't smoke cigarettes in bed.“ This was Beldon's first hotel fire for five years.

The Canfield Times gave the news in these words on page one：

ANOTHER BELDON HOTEL CATCHES FIRE

Last night Beldon firemen arrived just too late to save clothing, bedclothes and some furniture at the Seabreeze Hotel. An angry holiday瞞aker said, “An electric lamp probably started the fire. The bedroom lamps are very old at some of these hotels. When I put my bedside light on, I heard a funny noise from the lamp.

” We are glad to tell our readers that this sort of adventure does not happen in Canfield.

What are the facts, then? It is never easy to find out the exact truth about an accident. There was a fire at the Seabreeze Hotel last August: that is one fact. Do we know anything else? Yes, we know that firemen went to the hotel.

Now what do you think of the rest of the “news“ ?

1. The Canfield Times used the 玥eadline(标题)like this in order to make its readers think ___________.

A. hotels in Beldon often catch fire

B. hotels in Beldon don't often catch fire

C. this was the second fire at the Seabreeze Hotel

D. Beldon was a good place except that hotels there are not quite safe

【解析】 答案为 A。作者意图推断题。本文通过两个对手城市的报纸对同一件火灾事故的不同报道，对新闻报道的真实性提出了怀疑。ANOTHER BELDON HOTEL CATCHES FIRE中ANOTHER是个关键词，暗示了Beldon的宾馆火灾频繁。

高三英语复习课件 篇8

英语中动词有谓语和非谓语之分。谓语动词在人称和数上要与主语保持一致，而非谓语动词没有人称和数的变化。非谓语动词主要包括：动词不定式，动词的-ing形式和过去分词三种。

学非谓语动词必须要了解它们的形式和在句子中的功能，请看下面两个表格：

1.非谓语动词的时态和语态形式（以动词do为例）：

一般式 主动 to do doing 动词的过去分词只有一种形式即done。及物动词的过去分词常表示被动和完成，而个别动词(多数是不及物动词)只表示完成

被动 to have been done having been done

进行式 to be doing ×

完成进行式 to have been doing ×

2. 非谓语动词在句子中的功能：

不定式 √ √ √ √ √ √ ×

_ing形式 √ √ √ √ √ √ √

过去分词 × × √ √ √ √ ×

一． 动词不定式的时态：

不定式的一般式通常表示不定式动作发生在谓语动词之后或与谓语动词同时发生；不定式的进行式（通常用于动态延续性动词）表示不定式动作与谓语动作同步发生；不定式的完成式通常表示不定式动作先于谓语动词而发生或表示一个实际未发生的动作；不定式的完成进行式往往强调不定式动作在谓语动词之前一直在进行。例如：

1. When I spoke to him, he pretended ___________(look) for something here and there.

2. He looked tired. He seemed ______________(work) all night.

3. Charles Babbage is generally considered ___________(invent) the first computer.

4. I would love _________ (go) to the party last night but I had to work extra hours to finish a report.

5. He ordered the man __________ (go) there at once.

二． 动词不定式的语态：

一般情况下，在一个含有不定式的句子中，如果有不定式的逻辑主语（即不定式动作的执行者）该不定式常用主动形式；如果出现的是不定式的逻辑宾语（即不定式动作的承受者），该不定式常用被动形式。但是，下面几种结构却常用主动表示被动：

(1).在easy, difficult, hard, heavy, light, fit, nice, comfortable等表示性质特征的形容词之后的不定式或用这些词修饰一个名词后跟的不定式常用主动表示被动；

(2).少数动词如blame(责备), let(出租)等的不定式作表语时常用主动表示被动。

6. This sentence is easy ___________ (understand).

7. I can’t go out with you today, as I have a lot of clothes_________ (wash).

8. “Have you any clothes __________ (wash) today?” asked the maid (女佣).

9.Our school is a nice place _________ (visit).

10. I found the chair comfortable _________ (sit) in.

11. I think the question difficult ________ (answer).

12. It’s I who am ________ (blame).

13. The officer ordered the soldiers ________ (fire) the guns.

14. The officer ordered the guns _________ (fire).

三._ing形式的时态:

_ing形式的一般式通常表示该动作与谓语动词同时发生或发生在谓语之后；完成式则表示

动作先于谓语动词而发生。如：

15. ________ (Walk) through the park, I saw some lovely flowers.

16. He was praised for __________ (teach) for 60 years.

17. I heard him __________ (sing) when I passed his room.

18. _________ (Finish) the work, he went home.

19. He insisted on _________ (join) the army.

四._ing形式的语态：

一般情况下，需要找准-ing动词的逻辑主语，若它们之间是主谓关系，-ing动词常用

主动；若它们之间是动宾关系，-ing动词就要用被动。但在动词need, want, require,及形容

词worth之后的-ing必须用主动表示被动。如：

20. He won’t come without __________ (invite).

21. The flowers in the garden need _______ (water).

22. Thank you for _________ (give) us so much help.

23. The building ________ (build) now will be a hospital.

24. ________ (give) such a good chance, how could she let it slip?

25. The book is well worth ________ (read).

动词不定式和动词的_ing形式都可以在句子中作主语。

（1）、一般来说，不定式作主语时，通常表示一次性的、特指的、具体的或将来的动作；而_ing形式作主语时，通常表示一个经常性的、泛指的、或不具体的动作。如：

26. ________ (refuse) him is not easy this time.

27. _________ (walk) is a good form of exercise for both the young and old.

28. ________ (teach) English is my job.

29. ________ (be) a teacher is her greatest wish in the future.

（2）、当句子的主语和表语都是非谓语动词时，两者在形式上一般保持一致；比较状语从句中的主语形式通常也取决于主句里的主语形式。如：

30. ______ (see) is to believe.==________ (see) is believing.

31. ________ (say) is easier than to do.

32. ________ (speak) a foreign language is more difficult than reading it.

（3）、在日常英语中，为了句子结构的平衡，常用it作形式主语而将不定式或-ing放在句末

这时候要注意下面的习惯句型：

It + be + 形容词或名词+ (for / of sb.) + to do sth.

It + take + sb. +some time / sth. + to do sth.

It + be + no use / no good / useless / a waste of sth. / worth + doing sth.

There + be + no + doing sth. (做某事是不行或不可能的)

33. It was foolish of you _________ (give) up what you rightly owned.

34. There is no ________ (hold) back the wheel of history.

35. I think it’s no good _______ (argue) with your parents.

动词不定式和动词的_ing形式都可以在句子中作宾语。

（1）、有些及物动词后只能接动词不定式作宾语，不能接-ing形式，常见的有：hope, wish, expect, decide, promise, offer, agree, manage, pretend, plan, refuse, fail 等等。

（2）、有些及物动词后只能接动词的_ing形式作宾语，不能接不定式，常见的有：enjoy, imagine, risk, appreciate, suggest, advise, admit, miss, practise, forbid, avoid, resist, escape, delay, finish, permit, allow, mind, keep, consider, excuse 等等。

（3）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义相同，常见的有：begin, start, continue, intend, bear, attempt等等。但要注意，begin, start 如遇下面三种情况时接不定式为最佳：

A. 句子的主语是物而不是人时，如：The ice began to melt.

B. 当begin, start 用了进行时态时, 如：He’s beginning to understand it.

C. 当begin, start 后作宾语的动词属于心理活动、精神状态类动词（如realize, understand, love, like, know 等等）时，如：It began to rain and I began to realize I should go home.

（4）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义有细微差别，常见的动词有：like / love / prefer / hate to do sth.(表示一个特定的、一次性的、将来的动作)

like /love / prefer /hate doing sth. (表示一般的、习惯性的、或正在进行的动作)

36. I like _________ (swim) but I don’t like _______ (swim) today.

37. Would you love ________ (go) to the zoo with us?

38. I felt like _______ (cry) at the news.

（5）、有些动词后既可以接不定式，也可以接-ing形式作宾语，意义完全不同，常见动词有：

39. We must try ________ (finish) the work on time.

Let’s try _______ (work) out the maths problem in another way,

40. I remember ______ (see) her somewhere before.

You must remember _______ (post) the letter for me.

47. The baby needs ______ (look) after. =The baby needs ________ after.

You don’t need _______ (look) after the baby today.

48. Our school is well worth ________ (visit).

Our school is well worthy ________ (visit).= Our school is well worthy of _________.

（6）、介词后的宾语一般用动词的-ing形式，但要注意：but和except之后通常接不定式；介词之后若有连接词时也要接不定式。如：

49. I have no choice but _______ (wait).

50. He gave me some advice on how _______ (study) it well.

51. He has no idea of what _______ (do) next.

52. I was about ______ (go) out when it began to rain.

注意：A. 下面短语中的to是介词，后面要接动词的-ing形式而不接不定式。

devote---to---, look forward to, pay attention to, prefer---to---, lead to, be close to, refer to, belong to, as to, get down to, owing to, be / get /become used to(习惯于------),等等。

B.有些短语中介词经常省略，这时要注意接动词的-ing形式，如：be busy (in) doing sth., spend money /time (in) doing sth., have difficulty /trouble / problems (in) doing sth., prevent / stop ---(from) doing sth.,等等。

（7）、当不定式和_ing形式作“主语+谓语+宾语+补语”句型中的宾语时，要用it作形式宾语，把真正的宾语置于补语之后，常见句型有：

主语+ make / feel /think /find /consider, etc. + it + adj. / n. + (for / of sb.) + to do sth.

主语+ make /feel /think /find /consider, etc. + it + no good /no use /useless + doing sth.

所有的非谓语动词都可以在句子中作表语，其区别在：

（1）、不定式作表语通常表示一次性、特指的、将来的或具体的动作，有时还可以表示计划安排将要发生的事或一种命令要求。

（2）、-ing形式作表语通常表示习惯性、泛指的、不具体的动作或表示主语的性质特征（主要是一些表示感情情绪的词，译为“令人感到……的”）

（3）、过去分词作表语通常表示主语所处的状态，常具有被动含义（主要是一些表示感情情绪的词，译为“感到……的”），这样的动词常见的有：surprise, move, excite, interest, shock, tire, bore, touch, encourage, disappoint, invite, inspire, amuse等等。如：

53. No one is ______ (leave) this building without the permission of the police.

54. My job is ______ (teach) English and my wish is ______ (be) a lawyer.

55. The president is ______ (visit) our country next month.

56. The speech was very _________ (move) and we were all _______ (move) to tears.

所有的非谓语动词都可以作定语，其区别在：

（1）、不定式作定语常放在被修饰的名词之后，通常可以表示：

A. 一个发生在谓语动词之后的动作。如：

The building to be built next month will be a hospital.

B. 被修饰的名词与用作定语的不定式之间可能是逻辑上的“主+谓”关系，也可能是逻辑上的“动+宾”关系。如：

Do you have anyone to help you? (“主+谓”关系)

I have nothing to write. (“动+宾”关系) 我没有什么东西可写。

C. 如果是“动+宾”关系，动词不定式之后有时需要添上适当的介词，而在名词time, place, moment, way等之后的不定式所带的介词可以省略，如：

I have nothing to write on. 我没有什么东西可以上面写字。

I have nothing to write with. 我没有什么东西可以用来写字。

I have no time to rest.

注意：这种带介词的不定式短语常可以转换为“介词+which / whom+不定式”的结构。例：They had only a cold room to live in.==

They had only a cold room in which to live.

D. 下列情况常用不定式作定语：

当句子中的谓语是一些特定的动词，如：be, find, get, give, have, need, want等，它们后面的名词（宾语或表语）常用不定式修饰。

当名词前有特定的定语，如：first, last, next, only, second以及形容词最高级时，其后常用不定式作定语。

在There be句型中，主语之后常用不定式作定语。

有一些特定的名词之后常用不定式作定语，常见的有：time, chance, right, promise, wish, plan, means, ability等。

例：You have no right to speak here.

He is the only person to know the truth.

There is nothing to worry about.

My parents had no chance to go to college.

（2）、动词的_ing形式作定语时，如果是单个词，常放在被修饰名词之前；如果是-ing短语，要放在名词之后。_ing作定语通常可以表示：

A. 被修饰名词的用途，如：a sleeping car, a waiting room, a walking stick, etc.

B. 被修饰名词的性质特征，如：exciting news, a moving story, etc.

C．被修饰名词正在进行的动作，如：a falling leaf, a burning stick, boiling water, etc.

（3）、过去分词作定语通常表示：

A. 被动，如：He is a man loved by all the people.

B. 完成，如：The building built last year is our classroom building.

a fallen leaf, a developed country, boiled water

C. 被修饰名词所处的状态，如：an excited boy, the disappointed parents, surprised eyes, etc.

所有的非谓语动词都可以在句子中充当状语，其区别在：

（1）、不定式（短语）常在句子中作目的、结果和原因状语，常见句式有：

目的：to do sth.; in order to do sth.; so as to do sth.

结果：so + adj. /adv. + as to do sth.; such + n. + as to do sth.; enough to do sth.; too…to do sth.; only to do sth.

原因：be happy / glad / sorry / sad ,etc. + to do sth.

（2）、_ing形式和过去分词位于句首时常作时间、原因、条件状语，位于句末时主要作方式、伴随或结果状语。究竟该用_ing还是过去分词，主要取决于句子的主语，若它们之间是主动关系就用_ing形式，若是被动关系，就用过去分词。

57. He raised his hand ________ the taxi stop. (have)

58. _______ from the top of the hill, our school looks more beautiful. (see)

59. The parents died, _______ him an orphan. (leave)

60. ______ to college, he works very hard. (go)

61. I’m not such a boy as ______ him. (believe)

62. _______ ill, he was sent to a hospital. (be)

注意：A. 非谓语动词作状语时，其逻辑主语通常是句子的主语，如：

（×）Being a fine day, we went out for an outing.

（√）As it was a fine day, we went out for an outing.

（√）It being a fine day, we went out for an outing.

(×) Hearing the news, tears came to my eyes.

（√）Hearing the news, I burst into tears.

（√）When I heard the news, tears came to my eyes.

B．有些非谓语动词可以相当于独立成分、介词或连词使用，这时候它们常有自己固定的形式，与句子的主语不存在任何的逻辑关系，常见的有：

to tell (you) the truth, to be honest, (老实说)

generally / strictly / exactly speaking (一般/严格/准确地说)

including (其中包括……) compared with / to… (与……相比)

所有的非谓语动词都可以作补语，在使用中要注意下面几种情况：

（1）、有许多动词，如：ask, tell, allow, force, cause, encourage, 等之后都可以接不定式作宾语补足语。

（2）、在感官动词notice, observe, feel, hear, listen to, see, watch, look at之后可以接三种非谓语动词作补语，其区别在：_ing作补语表示与谓语动词同时进行的动作，如果这个动作与宾语是被动关系，还要用其被动形式being done；过去分词作补语常表示一个完成被动的动作；不定式作补语可以表示一个全过程、一个具体的、将来的、或经常性的动作。如：

63. I saw the classroom ________ (clean) when I passed by it.

64. The missing children were last seen ______ (play) by the river.

65. I often hear him ________ (sing) in the next room.

66. I saw the room _________ (clean). Everything was put in order.

67. I saw him ________ (open) the door, _______ (walk) into the room, and ______ (sit) down at the desk.

（3）、注意使让动词之后的补语用法：

A．have sb. do sth.==get sb. to do sth. “请/叫/让某人做某事” 与宾语的关系是主动的。

B．have sb./ sth. doing sth.“使某人一直做某事/容许某人做某事”，强调主动和进行。

C．get sb. doing sth.“使某人开始做某事”。

D．have sb./sth. done ==get sb./sth. done“使某人/某物被……或使……遭受……”，表示被动

E．make /let sb. do sth.表主动。

F. make /let sb. /sth. /oneself done 表示被动。

（4）、有些动词后不能接非谓语动词特别是不定式作宾语补足语，常考的动词有：agree, refuse, hope, suggest, demand, etc.

(5)、有些动词后需要接_ing作宾语，而接不定式作宾语补足语，常见的动词有：advise, allow, permit, forbid, encourage等。

例：68.You’d better have someone else _______ (help) you. I’m too busy.

69.He already had his eyes ________ (examine) in the hospital yesterday.

70.The speaker explained it again to make himself _______ (understand).

71.We don’t allow _____ (smoke) in our classroom.

72.He didn’t allow his son _____ (play) computer games.

动词的_ing形式常被用来解释一个名词的具体内容，在句子中充当同位语，如：

His habit, studying at night, remains unchanged.

The gesture for “OK”, making a circle with one’s thumb and index finger, has different meaning in different countries.

一、 否定结构：

所有非谓语动词的否定结构都是在非谓语动词前直接加否定词not或never等构成。

例：Excuse me for not coming back in time.

Not having received a reply, He decided to writer again.

He advised me never to go out alone at night.

不定式复合结构是指带有主语的动词不定式，其形式有以下两种：

（1）、for sb. to do sth.(侧重动作), 可以用于各种句子结构中。

（2）、of sb. to do sth.(侧重对逻辑主语品行的评价)，这种结构主要用于下列形容词之后：bad, brave, careful careless, clever, foolish, cruel, kind, rude, polite, stupid等。

73.It’s very important ____ us to learn English well.

74.It’s very foolish ____ you to believe him. == You are very foolish to believe him

75.There are a lot of difficulties ____ them to overcome.

76.I stepped aside ____ her to pass.

由动名词的逻辑主语和动词_ing一起构成，在句子中主要作主语和宾语，其形式有：

注意、A、当句子的主语就是_ing动词的逻辑主语时不能用复合结构。如：

Would you mind opening the door? (You open the door.)

Would you mind my / me opening the door? (I open the door.)

B、_ing作主语放在句首时，只能用第（1）种形式的复合结构。如：

His being ill made us very sad.

C、当无生命的名词或两个以上的名词/代词并列作_ing的逻辑主语时，只能用第（2）种形式的复合结构。如：

Can you hear the noise of the machine running.

Is there any hope of him and his sister winning the prize?

（1）、由“名词或代词主格+动词的_ing形式或过去分词”构成，在句子中作状语，可以表示时间、原因、条件、伴随情况或方式。主要用于句子的主语不是非谓语动词的逻辑主语时。如：

77.All the work_______ (do), he had a rest. （时间状语）

78.Weather ________ (permit), we will go outing tomorrow.（条件状语）

79.The boy stood there, his right hand _______ (raise). （伴随情况）

80.He _____ (be) ill, we sent him to a hospital. （原因状语）

81.There ______ (be) no buses, we had to walk home.（原因状语）

（2）、由“with/without +名词/代词宾格+动词_ing /过去分词/不定式/介词（短语）/形容词/副词”等构成，在句子中可以作状语或定语。如：

82.The murderer was brought in, with his hands _____ (tie) behind his back.

83.With a lot of work ____ (do), I can’t go to the cinema with you.

84.He left without anybody ______ (know).

五、“连接词+ to do”，“when/while/though/unless/if, etc. + done /doing”结构的区别

（1）、“连接词+to do”相当于一个名词的作用，在句中作主语、宾语和表语，常可以转换成由该连词引出的从句。

(2)、“when/while/though/unless/if, etc. + done/doing” 在句子中只能作状语，主句的主语是此结构中doing和done的逻辑主语，如果它们之间的关系是主动的，就用doing，是被动的就用done。

85. Please tell me what _______ (do ) next. ==Please tell me what I should do next.

86. The problem is whether _______ (go) by bus or by plane.

87. When ______ (start) the project hasn’t been decided yet.

88. Be careful when / while ________(cross) the street.

89. When________ (heat), ice will melt.

90. He won’t go to the party unless _______ (invite).

一、 省略不定式符号to的情况：

(1).不定式在感官动词notice, observe, feel, hear, listen to, see, watch, look at, 和使让动词have, make, let 之后作宾语补足语时，符号to必须省略。但是当这些动词用于被动语态时，动词不定式变为主语补足语，符号to不能省略。

例：We often hear him sing the song at home.→ He is often heard to sing the song at home.

(2).在动词help之后作宾语或宾语补足语的不定式，符号to可有可无。

(3).两个或两个以上的不定式由连词and / or / than / but 等连接时，从第二个不定式起的符号to常常省略。

例：The students are taught to read, write and do many other things.

例：It’s more difficult to do than to say.

The teacher came not to punish you but to help you.

I wondered whether to stay or to leave.

(4).不定式作表语，用来解释主语部分中do的内容时可以不带to。如：

What we want to do now is (to) lie down and rest.

The first thing she did was go up to her trainer and thank her.

(5).在why或why not引起的表示建议或责问的省略问句中不能带to。

Why quarrel with your mother? Why not join us?

(6).在一些类似情态动词的词组如：had better, would rather … than … , can’t (help / choose) but 等之后的动词不带to。

(7).不定式作but或except的宾语时，若前面有实意动词do / does / did / to do等形式，不带to。如：

I did nothing but / except do my homework last night.

She had nothing to do but wait.

(8).当助动词do / does / did用来加强语气或构成倒装句时，其后的动词不能带to。如：

Seldom does he go home this term. I did tell him the news.

(9).当dare用作实意动词时，后面的不定式有时也不带to，特别是在否定句中。

She didn’t dare (to) ask the teacher.

(10).在美国口语中，用在祈使语气中表示目的，在动词come / try / go / run等之后的不定式可以不带to。如：

Come tell me if he arrives. Go tell your mother. Try open the door again.

二、 省略to之后的动词部分的情况：

一般说来，当不定式内容是重复前面的内容时，to后的成分可以承前省略，但要保留符

号to，此时省略的成分相当于do so，这种结构一定要有上文或一定的语境。如：

_ Will you go with me? _ Well, I’d like to.

_ Why didn’t you bring an umbrella with you? _ I meant to, but I forgot about it.

The boy wanted to ride his bicycle in the street, but his mother told him not to.

He can’t eat as much as he used to.

注意：当不定式内容是助动词be / have时，to后要保留原形的be / have。如：

He hasn’t succeeded in the exam, but in fact he ought to have.

She is no longer what she used to be.

1. It shames me to say it, but I told a lie when _______ at the meeting by my boss.

分词有现在分词和过去分词两种。

作为非谓语形式，分词可用作形容词和副词，在句子中充当定语、表语、补语和状语。但它仍保持动词的一般特征，可以有自己的宾语和状语。分词和自己的宾语、状语构成分词短语。

现在分词有主动语态和被动语态(being + 过去分词)。

过去分词只有一般式，表示在谓语动词所表示的动作之前发生的动作。过去分词（及物动词）本身可以表示被动的含义，因而没有别的被动形式。

1．作定语。

我们结合《英语周报》高三广州专版第30,31期的专题复习内容研以及配套的例题分析(见《英语周报》),针对高考阅读理解的四种主要题型,给学生做解题策略指导和技巧总结.

策略指导：先浏览一遍题目，把题目的要求储存在大脑中，带着疑问去快速阅读，然后找出与题目相关的信息词句加以理解分析，去伪存真。此种办法能有效地避免做细节理解题时的失误。

【技巧总结】准确捕捉信息，注意对信息进行综合分析，分清主次、真伪，避免受信息的干扰，陷入高考题所设下的“陷阱”，误选干扰项，因为某些干扰选项在文章中也能找到“依据”，具有很强的迷惑性。

策略指导：深层含义通常是隐藏在文字背后的延伸之意，弦外之音，如作者的意图、倾向、语气，人物的性格、心理、情感，故事的结局，事情的因果关系等。因此大家需调动自己的逻辑思维能力，透过字里行间，去严密推理，合理想象。

【技巧总结】隐含信息并非“空穴来风”， 而是“有源之水”，即隐含信息也是以文章的语言为载体。大家应准确捕捉信息，调动智力因素，严密推理，合理想象，忌“凭空想象 ”或“断章取义”。在阅读理解中结合自己的常识进行判断是必要的，但决不能以常识取代信息分析。推理判断既要严密，又要灵活。

策略指导：首先从词汇所处的语境进行分析，注意上下文之间的关系，如：如果出现that is, that is to say或破折号等，我们可以断定，后面的内容是对前面内容的解释；如果出现转折词but, however, yet以及表示相反结果的on the contrary, on the other hand等，我们可以从所给内容相反的意义去考虑。

【技巧总结】高考语意判断题很多都是考查旧词新义的理解。因此大家需把词汇或短句的字面意义与语境和上下文结合起来，选择最切合文章内容，最符合上下文逻辑的意义，切忌望文生义。

策略指导： 读完一篇短文后应有意识地回味一下文章的大致内容，理一理文章的脉络，体会一下段与段之间的内在联系，这样做文章的中心一般都能概括出来, 涉及文章主旨大意方面的题目自然会在头脑中由模糊变清晰。

【技巧总结】我们在归纳文章主题时，一定要注意选项的内涵和外延必须能恰如其分地概括文章的主题，既不能范围过大，也不能把某一细节或侧面误当作主题。阅读时我们还应注意捕捉文章出现频率较高的中心词汇以及文章和段落的主题句。在选择文章题目时，还应注意语言方面的特点：文章题目往往具有凝练、醒目的特点。

猜测词义是从特定的角度考查考生的阅读理解能力和处理生词的能力。猜测词义包括对词、词组和句意的理解，是高考英语试题阅读理解中的一类必考题。猜测词义题常见的解题方法：

任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析而推测词义，是阅读过程中的一大关键，也是高考的热点。

如：If he thinks he can invite me out, he is all wet. I don’t like to be with him.

A. drunk B. sweating C. happy D. mistaken

分析：根据I don’t like to be with him我们感受到说话人的语气。我不愿意跟他在一起，那么，他要邀请我出去是不可能的 他就大错特错了。因此答案D。

阅读文章中的有些生词尤其是新闻报导及科普类文章中的生词，往往在其后有对该词进行解释说明性的短语或句子，如to be, that is , mean, stand for, namely, to refer to, to mean ,in other words等，有时也以同位语、定语从句的形式出现，或用破折号、括号来表示。

如：Some ships carried cargo such as coal, oil and military supplies(军用物资),while others carried only passengers.

分析：such as后所列举物品均为“货物”，由此推断cargo的意思相同，和后面的passengers形成对比。

有的文章作者为了增强表达效果，会用一对反义词揭示事物的不同点，形成鲜明的对比，这时只要把握其中的一词，就不难推出另一词的含义，这种句子多见unlike, although, but, yet, while, on the contrary, on the other hand, for one thing, for another, instead of, rather than等信息词。如：One idea about business is that it can be treated as a game of perfect information. Quite the reverse, business polite, life itself is games which we must normally play with very imperfect information.

A. Quite right. B. Time enough. C. Most unlike. D. Just the opposite.

分析：由前句中perfect information到后面imperfect information这一组对比关系的词，我们可以推断应为“对比、相反”的意思。

常见的引出同义词的标志性词语有or, like, similarly等。如：

Millions of animals die each year on Us roads, the Highway administration reports. In fact, only about 80 ocelots, an endangered wild cat exist in the US today. The main reason? Roadkill.

分析：从后面的同位语an endangered wild cat可知“ocelot”是一种野生猫

某些冷僻的词汇后面会举一个例子，使词汇具体易懂。等连接性词语往往用来举例说明前面较难理解的名词。

如：You can take any of the periodicals: The World of English, Foreign Language Teaching in School, or English Learning.

分析：通过后面的例子：《英语世界》、《中小学外语教学》、《英语学习》，可知periodicals为“期刊杂志”

阅读中常会遇到一些由所熟悉的单词派生或合成的新词，可利用构词法知识来推测其意思。

如：Exhibition officials said that a person bitten by one of these snakes would need at least 80ml of an anti-poison medicine to be saved.

分析：anti-poison 是由poison加前缀anti-构成的，anti-意思是“反对、排斥、抵抗”，由此可猜出anti-poison是“解毒、抗毒”的意思。

5. 结构复杂的长句子出现在阅读理解中往往造成大家心理上的紧张，有时读了好几遍还不知道句子的意思，白白浪费了时间,如何对待阅读理解中的长句子?

策略指导：阅读理解中的结构复杂的句子一般分为两大类：第一类是由复合句或并列句构成的长复杂句子；第二类是省略句。对于第一类句子，大家应抓其主干成分，理解其主体意思，其他的成分都是对主体意思的修饰和补充。对于第二类句子，大家应通过上下文找出省略成分，把句子补充完整。

【技巧总结】结构复杂的句子往往出现在说明文或议论文中，这是造成考生心理紧张的主要原因。大家应冷静下来，结合文章所说明或议论的中心话题，抓住主干，层层理解。

主要考察学生的速读能力，即在有限的时间内理解、总结信息并且能快速找到相关的信息的能力。学生要学会寻读（scan），抓关键信息，然后进行匹配。

Step 3 Homework and consolidation exercises

1. 《英语周报》高三广州专版第30,31期的专题复习内容。

2. 《英语周报》高三广州专版第33-34期的年高考英语模拟试题（一 ）--（十二）一共12套。

3. 和2007年全国各地的英语高考试题中的阅读理解。

阅读理解旨在考查考生理解总体和特定信息的能力。

任何一篇文章都有一个主旨要义。有时从文章的第一个段落甚至第一个句子即可以得出文章的主旨要义。从这个段落或句子，读者可以知道文章描述的是谁或什么即文章的主题，也会了解作者希望读者了解主题方面的哪些内容。有时，文章的主旨要义则需要从文章的字里行间进行推断。这类试题主要考查考生的略读文章、领会大意的能力，有时候它

对考生的归纳、概括能力有一定的要求。

一篇文章的主题和中心确定之后，还需要有大量的细节信息支持。这些细节对于理解全文的内容至关重要，同时也是归纳和概括文章中心思想的基础，因而不容忽视。

正确理解文章中单词或短语的含义是理解文章的第一步，也是理解文章的基础。不懂得单词的含义根本就谈不上理解文章。但是，有时候英语单词的含义并非等同于词典上标注的汉语意思，其含义随不同的语境会有所不同。根据上下文正确理解灵活多变的词义，

才算是真正初步具备了一定的阅读理解能力。

在实际阅读活动中，有时候需要根据文章提供的线索和事实，进行逻辑推理，推测作

者未提到的事实或某事情发生的可能性。

英语文章讲究主题段和主题句。主题段通常在文章的开头，主题句可能在某一段的开头、中间或结尾，作用是交代该段的中心思想，再由全段展开或讨论这个意思。段与段之间通常有词语连接，承上启下，使文章行文连贯。如果希望准确、深刻地理解一篇文章，必须对文章的结构有所了解，把握住全文的文脉，即句与句、段与段之间的逻辑关系。对

这种能力的考查一般反映在文章的中心思想、文中某段的大意或指代关系的题目中。

每篇文章都有一个特定的写作目的，或是向读者传递某个信息，或是愉悦读者，或是讲授某个道理。而这些信息通常不是明确表达出来，而是隐含在文章之中。因此，这类问

题要求考生在理解文章总体的基础之上，去领会作者的眼外之意。

下面结合2007年广东高考阅读理解试题，具体分析对这些能力的考查：

A

How should one invest a sum of money in these days of inflation (通货膨胀)? Left in a bank it will hardly keep its value, however high the interest rate. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your saving and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.

I sometimes wonder what a being from another planet might report back about our way of life. “The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound, it has a face with twelve black marks and two hands. Men can do nothing without it's permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves. ” Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time of day according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout the time. So it seems that the first clocks were human beings.

However, men quickly found more convenient and reliable ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hourglasses, and invented water-clocks. Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.

Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by time, why not invest in an antique clock and perhaps make a future profit?

41. According to the passage, collecting antique clocks______.

A. can hardly keep the value of your savings

B. will cost much of your savings

42. By quoting (引用) the remark of a being from another planet, the author intends to________.

43. Which of the following is NOT mentioned as a way to measure the time?

A. Counting the beating of one's own heart.

B. Making use of candles, sand and water.

C. Observing shadows cast by the sun.

D. Keeping slaves busy day and night.

44. The underlined phrase “stately homes”in paragraph 4 means________.

B. houses in very good condition

C. grand houses open to the public

D. houses where statesmen meet regularly

45. The purpose of the passage is_______.

A. to introduce the culture of antique clocks

B. to offer some advice on collecting antique clocks

C. to compare different ways to make a future profit

D. to explain convenient and reliable ways of telling time

[导读] 这是一篇叙议结合的散文。人们在通货膨胀的今天应该怎样投资一笔钱呢？存在银行里，这笔钱几乎不能够保值，无论存款利息多么高。只有勇敢的人或是富有者才敢于在股票市场买卖。今天保护你的储蓄甚至增加你的财富最好方法之一似乎是购买过去遗传下来的漂亮的物品。因此，作者顺理成章地提出一些关于收藏古董闹钟的忠告，奉劝人

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.

Here's an example to show how honorable actions create happiness.

Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.

Then, what is it to do with our sense of happiness?

In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.

There is a beautiful positive cycle that is created by living a life of honorable actions.

Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

46. According to the passage, the positive action in the example contributes to our .

47. The author thinks that keeping silent about the uncharged item is equal to .

48. The phrase “bringing the error to the clerk's attention” (in para. 5) means .

A. telling the truth to the clerk

C. asking the clerk to be more attentive

D. reminding the clerk of the charged item

49. How will we feel if we let the clerk know her mistake?

A. We'll be very excited.

B. We'll feel unfortunate.

C. We'll have a sense of honor.

D. We'll feel sorry for the clerk.

50. Which of the following can be the best title of this passage?

D. Happiness through Honorable Actions

[导读] 这是一篇说理、规劝性的议论文。本文的中心是：作者提倡通过高尚的行为获得幸福，规劝人们多行善事获得幸福，以形成一种美丽的积极的循环。高尚的思想行为可以使你的生活具有一种和平感、幸福感、善良感和自尊感。过高尚行为的生活可以创造美丽的积极的循环。高尚的思想导致高尚的行为。高尚的行为致使我们幸福的生存。当我们幸福的时候，我们容易产生高尚的思想和行为。虽然积极的循环难以开启，但是，一旦开启，就容易继续下去。坚持不断地做善事会给我们到来平静的心理，这样做对我们的幸福

46. A。细节事实理解题。第5段第6-8句：In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased.比较而言，把这个错误引起这个职员的注意导致几件事情发生。职员立刻知道我们是高尚的（honorable）。我

自己就是小偷。

48. A。句子意思猜测题。第5段分两层意思。第1-5句是第一层意思：在第一个案例中，我们不告诉那个职员，有几件事情会发生。在内心深处我们会知道我们自己就是小偷。在这个过程中，我们的心理会失去平静，也失去自尊。我们也会证明我们不可以信赖，因为我们通过告诉家里的人和朋友的方式来忠告我们的耻辱。第5段第6-8句是第二层意思：比较而言，把这个错误引起这个职员的注意导致几件事情发生。职员立刻知道我们是高尚的（honorable）。我们一离开商店，就感觉到是高尚的，并且我们的自尊在增加。通过对比这两层意思，可以判断bringing the error to the clerk's attention意思是“实话告诉这个职

员”。

49. C。细节事实理解题。第5段第7-8句：Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. 职员立刻知道我们是高尚的（honorable）。我们一离开商店，就感觉到是高尚的，并且我们的自

Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.

Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.

For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

51. According to paragraph I, many people don't seek care because .

C. they can remain unaffected for long

D. there are too many people suffering from the disease

52. People suffering from malaria .

A. have to kill female mosquitoes

B. have ability to defend parasites

C. have their red blood cells infected

D. have sudden fever, followed by chills

53. Which of the following may be the reason for the wide spread of the disease?

A. Its resistance to global warming.

B. Its ability to pass on the virus frequently.

C. Its outbreaks in cities with large populations.

D. Its ability to defend itself and resist new drugs.

54. It can be inferred from the passage that .

A. no drugs have been found to treat the disease

B. the alternative treatment is not easily available to most people

C. malaria has developed its ability to resist parasites

D. nobody knows what will be the drug to treat the disease

55. Which of the following questions has NOT been discussed in the passage?

A. How can we know one is suffering from malaria?

B. How many people are killed by malaria each year?

C. Why are there so many people suffering from malaria?

D. What has been done to keep people unaffected for long?

[导读] 这是一篇介绍医学科普常识的说明文。本文主要介绍疟疾病的起因、传播、危害与治疗。疟疾（Malaria）是世界上传播最广泛的寄生虫引起的病，每年都要使三百万人致命--几乎全是5岁以下的孩子，并且是贫穷的非洲人。疟疾病本身有很多基因，对于各种新药物具有抵抗性，所以目前还没有找到根治疟疾病的最佳治疗方法和药物。

51. A。细节事实理解题。见第1段第2-3句：... because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. (多年来，有5亿多病例由这种病引起的，虽然确切的数字难以估计，) 因为许多人不去寻求（或不可能）医疗护理。这种情况对于一个年收入不到200美元的家庭并非不同寻常，因为要治疗疟疾病，

就花去年收入的四分之一，并且他们时常所得到的不再有效。

52. C。细节事实理解题。见第2段第3句：Malaria parasites live by eating the red blood cells they infect (感染) .疟疾寄生虫依靠吃他们感染的红血球生存。这说明疟疾病患者的红

血球受到感染。

53. D。细节事实理解题。这种疾病之所以广泛传播是因为它有一种自我防御和抵抗新药物的能力。见第2段倒数第3句：Malaria has five thousand genes, and its ability to change

rapidly to defend itself and resist new drugs has made it nearly impossible to control.。

54. B。推理判断题。根据第3段倒数第2句：Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. 一些成功的可供选择的化学药品在阻止疟疾的这种抵抗力方面已经出现效用，但是这些可供选

择的化学药品非常短缺，并且昂贵，因此大多数人不容易得到可供选择的治疗。

55. D。细节事实理解题。A项见第2段第1句：Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches；B项见第1段第1句：... kills as many as three million people every year almost all of whom are under five, very poor, and African.；C项见第2段第3句：Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.；又见第1段第2

句：... because many people don't (or can't) seek care.；D项没有提到。

高三数学复习课件 篇2

一.课标要求：

(1)空间向量及其运算

① 经历向量及其运算由平面向空间推广的过程;

② 了解空间向量的概念，了解空间向量的基本定理及其意义，掌握空间向量的正交分解及其坐标表示;

③ 掌握空间向量的线性运算及其坐标表示;

④ 掌握空间向量的数量积及其坐标表示，能运用向量的数量积判断向量的共线与垂直。

(2)空间向量的应用

① 理解直线的方向向量与平面的法向量;

② 能用向量语言表述线线、线面、面面的垂直、平行关系;

③ 能用向量方法证明有关线、面位置关系的一些定理(包括三垂线定理);

④ 能用向量方法解决线线、线面、面面的夹角的计算问题，体会向量方法在研究几何问题中的作用。

二.命题走向

本讲内容主要涉及空间向量的坐标及运算、空间向量的应用。本讲是立体几何的核心内容，高考对本讲的考察形式为：以客观题形式考察空间向量的概念和运算，结合主观题借助空间向量求夹角和距离。

预测20xx年高考对本讲内容的考查将侧重于向量的应用，尤其是求夹角、求距离，教材上淡化了利用空间关系找角、找距离这方面的讲解，加大了向量的应用，因此作为立体几何解答题，用向量法处理角和距离将是主要方法，在复习时应加大这方面的训练力度。

三.要点精讲

1.空间向量的概念

向量：在空间，我们把具有大小和方向的量叫做向量。如位移、速度、力等。

相等向量：长度相等且方向相同的向量叫做相等向量。

表示方法：用有向线段表示，并且同向且等长的有向线段表示同一向量或相等的向量。

说明：①由相等向量的概念可知，一个向量在空间平移到任何位置，仍与原来的向量相等，用同向且等长的有向线段表示;②平面向量仅限于研究同一平面内的平移，而空间向量研究的是空间的平移。

2.向量运算和运算率

加法交换率：

加法结合率：

数乘分配率：

说明：①引导学生利用右图验证加法交换率，然后推广到首尾相接的若干向量之和;②向量加法的平行四边形法则在空间仍成立。

3.平行向量(共线向量)：

如果表示空间向量的有向线段所在的直线互相平行或重合，则这些向量叫做共线向量或平行向量。 平行于 记作 ∥ 。

注意：当我们说 、 共线时，对应的有向线段所在直线可能是同一直线，也可能是平行直线;当我们说 、 平行时，也具有同样的意义。

共线向量定理：对空间任意两个向量 ( )、 ， ∥ 的充要条件是存在实数 使 =

注：⑴上述定理包含两个方面：①性质定理：若 ∥ ( 0)，则有 = ，其中 是唯一确定的实数。②判断定理：若存在唯一实数 ，使 = ( 0)，则有 ∥ (若用此结论判断 、 所在直线平行，还需 (或 )上有一点不在 (或 )上)。

⑵对于确定的 和 ， = 表示空间与 平行或共线，长度为 | |，当 0时与 同向，当 0时与 反向的所有向量。

⑶若直线l∥ ， ，P为l上任一点，O为空间任一点，下面根据上述定理来推导 的表达式。

推论：如果 l为经过已知点A且平行于已知非零向量 的直线，那么对任一点O，点P在直线l上的充要条件是存在实数t，满足等式

①其中向量 叫做直线l的方向向量。

在l上取 ，则①式可化为 ②

当 时，点P是线段AB的中点，则 ③

①或②叫做空间直线的向量参数表示式，③是线段AB的中点公式。

注意：⑴表示式(﹡)、(﹡﹡)既是表示式①,②的基础，也是常用的直线参数方程的表示形式;⑵推论的用途：解决三点共线问题。⑶结合三角形法则记忆方程。

4.向量与平面平行：

如果表示向量 的有向线段所在直线与平面 平行或 在 平面内，我们就说向量 平行于平面 ，记作 ∥ 。注意：向量 ∥ 与直线a∥ 的联系与区别。

共面向量：我们把平行于同一平面的向量叫做共面向量。

共面向量定理 如果两个向量 、 不共线，则向量 与向量 、 共面的充要条件是存在实数对x、y，使 ①

注：与共线向量定理一样，此定理包含性质和判定两个方面。

推论：空间一点P位于平面MAB内的充要条件是存在有序实数对x、y，使

④或对空间任一定点O，有 ⑤

在平面MAB内，点P对应的实数对(x, y)是唯一的。①式叫做平面MAB的向量表示式。

又∵ 代入⑤，整理得

⑥由于对于空间任意一点P，只要满足等式④、⑤、⑥之一(它们只是形式不同的同一等式)，点P就在平面MAB内;对于平面MAB内的任意一点P，都满足等式④、⑤、⑥，所以等式④、⑤、⑥都是由不共线的两个向量 、 (或不共线三点M、A、B)确定的空间平面的向量参数方程，也是M、A、B、P四点共面的充要条件。

5.空间向量基本定理：如果三个向量 、 、 不共面，那么对空间任一向量，存在一个唯一的有序实数组x, y, z, 使

说明：⑴由上述定理知，如果三个向量 、 、 不共面，那么所有空间向量所组成的集合就是 ，这个集合可看作由向量 、 、 生成的，所以我们把{ ， ， }叫做空间的一个基底， ， ， 都叫做基向量;⑵空间任意三个不共面向量都可以作为空间向量的一个基底;⑶一个基底是指一个向量组，一个基向量是指基底中的某一个向量，二者是相关联的不同的概念;⑷由于 可视为与任意非零向量共线。与任意两个非零向量共面，所以，三个向量不共面就隐含着它们都不是 。

推论：设O、A、B、C是不共面的四点，则对空间任一点P，都存在唯一的有序实数组 ，使

6.数量积

(1)夹角：已知两个非零向量 、 ，在空间任取一点O，作 ， ，则角AOB叫做向量 与 的夹角，记作

说明：⑴规定0 ,因而 = ;

⑵如果 = ，则称 与 互相垂直，记作

⑶在表示两个向量的夹角时，要使有向线段的起点重合，注意图(3)、(4)中的两个向量的夹角不同，

图(3)中AOB= ，

图(4)中AOB= ,

从而有 = = .

五.思维总结

本讲内容主要有空间直角坐标系，空间向量的坐标表示，空间向量的坐标运算，平行向量，垂直向量坐标之间的关系以及中点公式.空间直角坐标系是选取空间任意一点O和一个单位正交基底{i，j，k｝建立坐标系，对于O点的选取要既有作图的直观性，而且使各点的坐标，直线的坐标表示简化，要充分利用空间图形中已有的直线的关系和性质;空间向量的坐标运算同平面向量类似，具有类似的运算法则.一个向量在不同空间的表达方式不一样，实质没有改变.因而运算的方法和运算规律结论没变。如向量的数量积ab=|a||b|cos在二维、三维都是这样定义的，不同点仅是向量在不同空间具有不同表达形式.空间两向量平行时同平面两向量平行时表达式不一样，但实质是一致的，即对应坐标成比例，且比值为 ，对于中点公式要熟记。

对本讲内容的考查主要分以下三类：

1.以选择、填空题型考查本章的基本概念和性质

此类题一般难度不大，用以解决有关长度、夹角、垂直、判断多边形形状等问题。

2.向量在空间中的应用

在空间坐标系下，通过向量的坐标的表示，运用计算的方法研究三维空间几何图形的性质。

在复习过程中，抓住源于课本，高于课本的指导方针。本讲考题大多数是课本的变式题，即源于课本。因此，掌握双基、精通课本是本章关键。

②翻折前后应注意哪些量的位置和数量发生了变化， 哪些没变？

例2 如图，已知边长为a的等边三角形 所在平面外有一点P，使PA=PB=PC=a，求二面角 的大小。

[说明] ①求二面角的步骤：作证算答。

②引导学生掌握解题可操作性的通法（定义法和线面垂直法）。

[说明]使学生明白数学既来源于实际又服务于实际。

三、巩固练习

1。在棱长为1的正方体 中，求二面角 的大小。

2。 若二面角 的大小为 ，P在平面 上，点P到 的距离为h，求点P到棱l的距离。

四、课堂小结

1。二面角的定义

2。二面角的平面角的定义及其范围

3。二面角的平面角的常用作图方法

4。求二面角的大小（作证算答）

五、作业布置

1。课本P18练习14。4（1）

2。在 二面角的一个面内有一个点，它到另一个面的距离是10，求它到棱的距离。

3。把边长为a的正方形ABCD以BD为轴折叠，使二面角A—BD—C成 的二面角，求A、C两点的距离。

六、教学设计说明

本节课的设计不是简单地将概念直接传受给学生，而是考虑到知识的形成过程，设法从学生的数学现实出发，调动学生积极参与探索、发现、问题解决全过程。二面角及二面角的平面角这两大概念的引出均运用了类比的手段和方法。教学过程中通过教师的层层铺垫，学生的主动探究，使学生经历概念的形成、发展和应用过程，有意识地加强了知识形成过程的教学。

知识网络

15.1 复数的概念及其运算

典例精析

题型一 复数的概念

【例1】 (1)如果复数(m2+i)(1+mi)是实数，则实数m= ;

(2)在复平面内，复数1+ii对应的点位于第 象限;

(3)复数z=3i+1的共轭复数为z= .

【解 析】 (1)(m2+i)(1+mi)=m2-m+(1+m3)i是实数1+m3=0m=-1.

(2)因为1+ii=i(1+i)i2=1-i，所以在复平面内对 应的点为(1，-1)，位于第四象限.

(3)因为z=1+3i，所以z=1-3i.

【点拨】 运算此类 题目需注意复数的代数形式z=a+bi(a，bR)，并注意复数分为实数、虚数、纯虚数，复数的几何意义，共轭复数等概念.

【变式训练1】(1)如果z=1-ai1+ai为纯虚数，则实数a等于()

A.0 B.-1 C.1 D.-1或1

(2)在复平面内，复数z=1-ii(i是虚数单位)对应的点位于()

A.第一象限 B.第二象限 C.第三象限 D.第四象限

【解析】(1)设z=xi，x0，则

xi=1-ai1+ai1+ax-(a+x)i=0 或 故选D.

(2)z=1-ii=(1-i)(-i)=-1-i，该复数对应的点位于第三象限.故选C.

题型二 复数的相等

【例2】(1)已知复数z0=3+2i，复数z满足zz0=3z+z0，则复数z= ;

(2)已知m1+i=1-ni， 其中m，n是实数，i是虚数单位，则m+ni= ;

(3)已知关于x的方程x2+(k+2i)x+2+ki=0有实根，则这个实根为 ，实数k的值为.

【解析】(1)设z=x+yi(x，yR)，又z0=3+2i，

代入zz0=3z+z0得(x+yi)(3+2i)=3(x+yi)+3+2i，

整理得 (2y+3)+(2-2x)i=0，

则由复数相等的条件得

解得 所以z=1- .

(2)由已知得m=(1-ni)(1+i)=(1+n)+(1-n)i.

则由复数相等的条件得

所以m+ni=2+i.

(3)设x=x0是方程的实根， 代入方程并整理得

由复数相等的充要条件得

解得 或

所以方程的实根为x=2或x= -2，

相应的k值为k=-22或k=22.

【点拨】复数相等须先化为z=a+bi(a，bR)的形式，再由相等 得实部与实部相等、虚部与虚部相等.

【变式训练2】(1)设i是虚数单位，若1+2i1+i=a+bi(a，bR)，则a+b的值是()

A.-12 B.-2 C.2 D.12

(2)若(a-2i)i=b+i，其中a，bR，i为虚数单位，则a+b=.

【解析】(1)C.1+2i1+i=(1+2i)(1-i)(1+i)(1-i)= 3+i2，于是a+b=32+12=2.

(2)3.2+ai=b+ia=1，b= 2.

题 型三 复数的运算

【例3】 (1)若复数z=-12+32i， 则1+z+z2+z3++z2 008= ;

(2)设复数z满足z+|z|=2+i，那么z= .

【解析】 (1)由已知得z2=-12-32i，z3=1，z4=-12+32i =z.

所以zn具有周期性，在一个周期内的和为0，且周期为3.

所以1+z+z2+z3++z2 008

=1+z+(z2+z3+z4)++(z2 006+z2 007+z2 008)

=1+z=12+32i.

(2)设z=x+yi(x，yR)，则x+yi+x2+y2=2+i，

所以 解得 所以z= +i.

【点拨】 解(1)时要注意x3=1(x-1)(x2+x+1)=0的三个根为1，，-，

其中=-12+32i，-=-12-32i， 则

1++2=0， 1+-+-2=0 ，3=1，-3=1，-=1，2=-，-2=.

解(2)时要注意|z|R，所以须令z=x +yi.

【变式训练3】(1)复数11+i+i2等于()

A.1+i2 B.1-i2 C.-12 D.12

(2)(20xx江西鹰潭)已知复数z=23-i1+23i+(21-i)2 010，则复数z等于()

A.0 B.2 C.-2i D.2i

【解析】(1 )D.计算容易有11+i+i2=12.

(2)A.

总结提高

复数的代数运算是重点，是每年必考内容之一，复数代数形式的运算：①加减法按合并同类项法则进行;②乘法展开、除法须分母实数化.因此，一些复数问题只需设z=a+bi(a，bR)代入原式后，就 可以将复数问题化归为实数问题来解决.

【概率统计复习】

一、知识梳理

1.三种抽样方法的联系与区别：

类别共同点不同点相互联系适用范围

简单随机抽样都是等概率抽样从总体中逐个抽取总体中个体比较少

系统抽样将总体均匀分成若干部分;按事先确定的规则在各部分抽取在起始部分采用简单随机抽样总体中个体比较多

分层抽样将总体分成若干层，按个体个数的比例抽取在各层抽样时采用简单随机抽样或系统抽样总体中个体有明显差异

(1)从含有N个个体的总体中抽取n个个体的样本，每个个体被抽到的概率为

(2)系统抽样的步骤：①将总体中的个体随机编号;②将编号分段;③在第1段中用简单随机抽样确定起始的个体编号;④按照事先研究的规则抽取样本.

(3)分层抽样的步骤：①分层;②按比例确定每层抽取个体的个数;③各层抽样;④汇合成样本.

(4)要懂得从图表中提取有用信息

如：在频率分布直方图中①小矩形的面积=组距=频率②众数是矩形的中点的横坐标③中位数的左边与右边的直方图的面积相等，可以由此估计中位数的值

2.方差和标准差都是刻画数据波动大小的数字特征，一般地，设一组样本数据，，…，，其平均数为则方差，标准差

3.古典概型的概率公式：如果一次试验中可能出现的结果有个，而且所有结果都是等可能的，如果事件包含个结果，那么事件的概率P=

特别提醒：古典概型的两个共同特点：

○1，即试中有可能出现的基本事件只有有限个，即样本空间Ω中的元素个数是有限的;

○2，即每个基本事件出现的可能性相等。

4.几何概型的概率公式：P(A)=

特别提醒：几何概型的特点：试验的结果是无限不可数的;○2每个结果出现的可能性相等。

一日之计在于晨，对一般人来说，疲劳已消除，头脑最清醒，体力亦充沛，是学习的黄金时段。可安排对功课的全面复习。

早上8点-9点：

据试验结果显示，此时人的耐力处于状态，正是接受各种“考验”的好时间。可安排难度大的攻坚内容。

上午9点-11点：

试验表明这段时间短期记忆效果很好。对“抢记”和马上要考核的东西进行“突击”，可事半功倍。

正午13点-14点：

饭后人易疲劳，夏季尤其如此。休息调整一下，养精蓄锐，以利再战。休息，也可听轻音乐。但午休切莫过长。

下午15点-16点：

调整后精神又振，试验表明，此时长期记忆效果非常好。可合理安排那些需“永久记忆”的东西。

傍晚17点-18点：

试验显示这是完成复杂计算和比较消耗脑力作业的好时间。这段时间适宜做复杂计算和费劲作业。

晚饭后：

应根据各人情况妥善安排。可分两三段来学习，语、数、外等文理科交叉安排;也可作难易交替安排。

以下是一位高考优秀考生的每日作息时间表，可供参考：

每天6：00起床，6：30-7：30复习英语，7：40-9：40复习数学，9：50-11：50机动安排;中午午休;下午2：00-4：00复习化学，4：10-6：10复习物理;晚上2个小时复习语文;其余时间机动。在每一门课的复习中，不同阶段以不同内容为主，多看课本或多做习题，要掌握好。

高三英语复习计划【二】

一、学情分析

根据高二期末考试的情况我校高三学生的英语学习状况不容乐观，主要存在的问题是：学生基础知识不扎实，这表现在学生的语言运用能力差，阅读与完形的失分现象普遍，书面表达明显存在诸多不规范现象。

二、复习目标

在帮助学生全面且系统地掌握高中所学英语基础知识的同时，狠抓阅读与写作。

三、复习策略

1.守住“

阅读”，促进综合能力提升。坚持知识与能力同步进行，在复习基础知识过程中依然要关注学生语言运用能力的发展，既要突显知识网络的构建，通过使学生能归纳使学生的知识系统化，促进学生迁移能力的发展，更要活化学生所学知识，在不同的情境中运用所学知识。在整个复习过程中始终把“阅读”能力放在重要的位置，以其来丰富学生的背景知识，带动其它能力的发展。

2.认真“选题”，把好学生训练的质量关。各位老师把好习题的质量关，这是提高练习效率的前提条件。以最近5年各地高考试题与模拟试题为主，让学生在应试能力训练的过程中加强对高中阶段所学语言知识的巩固，提高学生的应试技能。教师在讲评练习时。不要只求答案，要进行多角度设问，使学生既要知其然，更要知其所以然，要通过典型试题分析，培养学生举一反三、触类旁通的能力。

3.及时“反馈”，强化学生复习的成就感。在复习的过程中要注重学生非智力因素的作用，及时进行训练效果的反馈，对于每个学生在复习过程中所表现出的积极态度，用心的付出，滴的进步都给予表扬与鼓励，使枯燥的复习充满活力与人情味，强化学生复习的成就感，提高学习的质量。

4.以“实践”为途径，促进能力转化。现在的高考越来越淡化单纯的语法知识考查，而是突出强调考查运用英语的能力。既然高考是以考核听、读、写能力为主，那么这些能力的培养只能靠不断地练习，在实践中使学生诸方面的能力逐步提高。课堂时间毕竟有限，教师应该处理好讲和练的关系。如果教师在课堂上的讲解时间过多，就必然挤占学生用于语言实践的时间。

高三英语复习计划【三】

一、核心策略：巩固词汇量

高考词汇表包括了高考要考的所有词汇，学生必须将词汇表从头到尾背3-4遍。方法是先将词汇表过一遍，熟悉和简单的一带而过。重点放在不熟悉的和重要的词汇上。离高考只有一个月左右的时间，每隔一星期就将词汇表整个过一遍。抓好了词汇，高考英语就有了成功的前提。 坚持每天检查，特别是那些可上可下的“临界考生”。确保词汇过关，这是学好英语、考好英语的前提。

二、提高试卷讲评课效率

这一阶段针对语法词汇、完形填空、阅读理解、写作这几大板块印发大量的各种题型练习。提高试卷讲评课效率。考试的过程比上课重要，而评讲课比考试过程更重要。评讲课可以帮助学生进一步理解知识、熟练技能、祢补缺漏、纠正错误、总结经验、拓展思路、揭示规律、提高能力。

讲评课应该注意的问题：

1，认真收集反馈信息：主要收集典型性问题。

2，讲评要有针对性，突出重点：要抓住典型性问题加以点拨剖析。切忌面面俱到，不要什么问题都讲，以免浪费大家时间;

3，要引导学生积极参与讲评：切忌老师包办代替、“一言谈”、满堂灌，而要引导学生共同分析试卷，总结学习经验，试卷讲评要给学生留出自查自改的时间，先把对错改出来，引导学生学会自我剖析、自我评价、自我改进学习方法、自我明确努力方向。通过评讲调动积极性，发挥主观能动性。不能挖苦讽刺考得不好的学生，而是要帮助他们认真分析原因，帮助他们祢补缺漏、树立信心，争取下次考得更好。

三 ，实战训练，练出高考的感觉

高考进入白热化的模拟题复习阶段，这是最有针对性和容易提高水平的复习阶段。要求学生

1，要保持模拟高考的状态，测时间做题，但可以不必像高考一样反复检查。

2，对每次模拟提出一个分值目标，与同学竞争，与自己竞争，这样才会产生精益求精的心理，在竞争心理驱使下竞技状态将大为提升，其效果是漫不经心地应付所不能比拟的。

3，做题后对错题失分“斤斤计较”，“耿耿于怀”也会驱使你搞得更清楚，印象更深刻。

4， 每个人都有自己的解题习惯和自己所长的项目。因此，要有得分意识。拿到手的分才算自己的分。先做自己有把握的题，让这些分拿到手再说。最后做自己感到难的题，并找出适合自己的英语试题解题的顺序。

四，重视书面表达和听力训练

1，做好听力的大力宣传工作， 特别要强化听力第一节即前5小题的训练与解题策略指导。

2，坚持每天有听力，在高考前，继续精选与高考听力考题题型一致、难度适当、语速适中的由英美人士录制的材料来加强训练， 教师进行适当点评。加强检查，尤其针对哪些高考临界生。

3，把高考书面表达评分标准印发给学生。让其知道评分的来龙去脉。以便有针对地训练。

4，训练时特别强调正确是根本。运用正确与否也会在一定程度上影响到考生的成绩。语法结构和词汇是写作部分评分标准中的一项重要内容。准确地道使用语法和词汇，用词面要宽，句式要有变化，并适当注意连接词的应用，这样就可以写出高分作文。不过还要注意拼写和标点符号的正确性，给人一个好印象，才可能成就高分。

5，每周要求写上一两篇作文练手，把到一近三年全国及各地高考题中的写作范文用心读一读、背一背，千方百计强调作文是写出来的。

6，优化批改和讲评的过程。在批改中，鼓励学生运用高级词汇和复杂结构，适当使用过渡词。讲评时可以把学生的典型错误列出来，进行有针对性地讲评和让学生们去比较。要训练同一内容的不同表达

方式，同一题材作文的一题多写，丰富学生的语言结构和语言表达方式。面批对“临界生”特别有效果。

五，了解学生特点 吃透考纲要点

降低难度，抓基本题，迎合《考试大纲》和《高考词汇表》

我们学校的学生属于层次不高的学生，因此我们主要练一般题，不练难题、怪题。关键是把中档、低档题把握住，这对取得高分是非常有利的。高考后期结合《考试大纲》和《高考词汇表》进行查漏补缺特别重要：大纲中新增加的词汇的用法，历届高考中出现率较高的词汇的用法都要特殊注意。对于考纲中新增加的词汇，要充分利用工具书，全面掌握其重点用法;对于历届高考中出现率较高的词汇，要掌握其命题规律和特点，求同存异，融会贯通。另外要强化知识链，力求知识的系统和完整。

六，对学生进行心理辅导，备战高考

教育学生临考前，不要去想考试成败将会给自己带来什么后果，尤其不夸大考试成败的影响，要想好万一考不好的“对策”，对自己的期望要实事求是;正确对待外来的压力。其次，考试前要休息好。临考前要减轻学习负担，要保证充分的睡眠，要适当进行文体活动，要保证身体键康。再次，在考试过程中，注意答卷顺序，按先易后难的答卷法。

高三后期的复习不是对前期已学知识的简单重复和强化，而是一个再学习、再认识、提高能力和运用能力，调整心态的过程。因此，我们必须在始终兼顾语言知识的前提下，重视学生语言能力的培养，加强应试技巧的训练，成功实现从语言知识到应用能力的转化、全面提高学生的英语语言素质，帮助他们掌握解题方法及技巧，最终提高做题的准确率和熟练程度，提高应试能力。

高三英语复习计划【四】

20xx年x月x日下午在四楼英语组办公室，英语组开展教研活动。鉴于我校学生英语基础较差的现状，为了学生能在复习时有所收获，有所进步，一个实用性的复习计划对他们来说极其重要。英语组所有成员经过讨论，制定以下高三英语复习计划：

练习：课时练、单元练、单元检测，穿插听力训练和限时阅读训练。

目的：积累知识，夯实基础，到边到角，全面具体，有的放矢。

方式：讲练结合，课前预习，课后巩固，跟踪辅导。

具体方式：

一、狠抓基础

词汇是高中英语最基本的要素，它好比是人身体上的肉，而语法是人身体上的骨骼，两者一起组成了人体，所以高中英语复习关键是词汇复习。以教材为基础，提炼出每个单元的重点单词，短语，句型，要求学生用学习的态度去对待复习，让他们从内心去体会英语单词，短语，句型在实践中的重要性。不但要求学生自主学习，老师应加大对学生的检查力度，通过上课提问，可而后听写，课下作业等各种方式，是学生能够把字，词，句应用到实际的练习中。

二、 练真题

总结高考相关类型的考题，尤其注重重点单词，短语在具体语境中的使用。对于每一单元的语法，我们采取了个人负责制，统一分配任务，制成试卷，内容分为两部分。一部分为语法讲解，另一部分为近三年来相关的语法高考题，通过讲解和练习相结合的方式帮助学生加强理解。不要盲目相信某个地区的模拟试题。英语水平较差的同学，完全没必要花很多时间去做模拟题中又难又怪的东西。要做适合自己的东西。边做边总结，练一段时间就停下来总结总结，争取记住自己犯过的错误，第二次第三次碰到类似的问题时保证不错。对学生进行语法专项指导，各个击破，一一掌握。并加以单项选择的解题技巧，提高学生分析问题和解答问题的能力。

三、背结构，会模仿

因为学生基础太差，所以最笨的方法有可能是最实在有用的.方法。正对每个单词，注意它们的含义，词性，词形等针对每个短语，让学生知道他们确切的意思后，学会辨别类似的短语。了解并区别他们的共性及区别，然后通过实践让学生在具体应用中活学活用。英语学习的重点是模仿，而不是理论分析。要模仿好，就要背一些东西。熟读熟背一些英语范文，可以使自己熟悉英文的习惯用法，熟悉英美人的思维方式，使自己写出说出的英语地道准确。

四、 重阅读

阅读是英语考试中份额最大的一部分，所以限时训练必不可少。我们计划每周抽出一节课。提供三篇有梯度的阅读理解，要求学生在规定时间内完成，然后立刻订正。逐渐培养学生的阅读兴趣，通过点滴积累，提升自我能力。在选择正确答案的同时，鼓励学生要充分利用平常所学过的阅读技巧。如寻找主题句，猜词，推理，跳读，略读等获取所需要的信息，并对照答案，反复揣摸作者意图及思路，并要求自己在单位时间内每天做一篇完形填空或阅读理解，坚持持之以恒的自我阅读训练，阅读速度和正确率定会日渐提高。因此每天必须让学生有阅读材料阅读并及时评讲。
