公共英语等级考试四级（PETS4）课程辅导（64）讲1

Part BInterlocutor:I’m going to give each of you a picture and I’d like you to first briefly describe and then give your comment on what you see in the picture.(put picture 1 in front of both candidates)Candidate A, this is your picture. You have three minutes to talk about it.Candidate B, listen carefully while Candidate A is speaking. When he/she has finished, I’d like you to ask him/her a question about what he/she has said.Candidate A, would you like to begin now, please?Candidate A:(Three minutes)on the top of the two pictures is the moon, which indicates it is late at night. The left picture shows what is going on in a karaoke club. The color lights above are shining and twinkling, and a crowd of young people are dancing with the music. In the middle of the picture, a man and a lady are standing in the front a video, singing happily. The man is laying his hand on the shoulder of the lady. They are enjoying themselves. Nowadays young people have more money and places to entertain themselves. After a whole day’s hard work, they go to various places to enjoy colorful nightlife, such as pubs, clubs, dancing parties and so on. While the picture on the right gives a strong contrast, an old lady sitting in sofa is watching TV. She wears a sad depressed expression. The room is so quiet that the cat lying on the ground has fallen to sleep. Her eyes are on the TV screen but her mind is far away. There is a picture on the wall-she once had a family of three. But now she can only live in the big house alone. Nowadays young people are busy with their own career and entertainment in the outside world away from the parents. Their parents are getting old and lonely since they are tired. For many reasons, the old are easily apt to depression. They are eager for mental comfort rather than money supply. They look forward to chances to get together with family members, to take care of their children, or just listen to them.Interlocutor:Thank you. Now, candidate B, could you please ask your partner a question?(Half a minute for asking and answering the question)B.Do you have any idea what the young should do to alleviate loneliness of the old?A. First, young people should spare some time to see their parents, and chat with them, and make them to know they are still of value for the family. Second, when at home, young people should try to create a warm atmosphere. Have a good time with the family to have a dinner together, or go to the park for a weekend. Third, if you are too busy to see them, at least you can give them a call, telling them what you are doing, and let them know they are still of importance for them. Forth, try to help them to take part in some social activities to make their life meaningful. In a word, young people should give their parents more attention and care.(Take back picture 1 and put picture 2 in front of both candidates)。

大学英语四级辅导讲义1

大学英语四级（ＣＥＴ－４）辅导讲义★第一讲★概述：新四级全接触四级考试在继2005年6月进行计分体制改革后，又进行了考试内容的改革，涉及到四级考试题型的变化，考试程序的改动，各题型分数比重的变动等。

改革后，新四级有什么特点，又应该如何应对，这些都是考生比较关注的问题。

把新老四级做个对比，可以看出新四级更加侧重学生的语言输入的速度和语言输出的能力。

下面从新四级的六个部分出发，对新四级作个详细分析。

第一部分是写作，这部分呈现考试程序变而考试要求不变的特点。

考试程序变。

以前的四级考试中，第一部分是听力，最后部分才是写作，而新四级第一部分就考写作，这种考试程序是向托福借鉴的结果。

第二部分快速阅读材料是30分钟后才发给考生，这样考生就需要更加合理有效利用完30分钟。

考生可以用5分钟左右仔细审题并且根据重点列出提纲，这样可以确保写作的方向是对的，写作的思路是明确的。

然后，用20至22分钟左右的时间写文章。

在写作时，一定要注意文章结构清晰，语言条理清楚，亮点偶尔闪现，包括单词的准确与变化，句子结构的多样化，合理的过渡词的使用等等。

最后，用3到5分钟检查修改文章，尤其注意时态和单复数的错误。

写作要求不变。

四级考试在内容改革前后，写作部分的要求没有任何变动，都是要求考生在30分钟内写完至少120个单词的文章。

而且从样题的分析来看，出题的方式和涉及的话题还会沿袭近几年的考法，会越来越与同学的真实生活接近，越来越强调实用性。

总之，考生可以按照以前的方法来准备写作部分。

第二部分是快速阅读，要求考生在15分钟内阅读大约1200个单词的文章，做完10个题目。

前7个题要求判断正误或未提及，后3个题要求根据文章内容把句子补充完整。

在这部分，特别强调考生在有限时间内了解文章大意，准确寻找重要细节的能力。

可以说，在信息大爆炸的现代社会，这是对考生阅读能力的很好引导。

考生要做好这部分，首先要有较快的阅读速度，同时还必须具备一定的阅读方法和技巧，大家可以参考下面的做题步骤：(1)、先看题目定方向。

公共英语等级考试四级（PETS4）课程辅导（42）讲1

英语四级考前辅导语法讲义

英语四级考前辅导：语法讲义第一节、解决四级英语长难句的意义1、阅读，抓不住句子重点，在一个句子上浪费太多时间。

最后根据不完整的理解，碰运气乱猜答案。

2、翻译，提笔不知从哪里下手;胡乱写几行，卷面乱，不知所云，影响印象分。

(一)长难句到底难在哪里? --几句废话般的常识。

1)结构复杂，逻辑层次多;2)单词意思常需根据上下文判断;3)代词的指代关系复杂;4)并列成分多;5)修饰语多，特别是后置定语很长;6)习惯搭配。

注：以上情况有可能单独出现，更多是“团伙作案”。

(二)长难句的破解的几个基本要点·把握规律(按照所讲的基本方法)·充分利用现有语法、词汇知识，提高知识的产出效率。

·破解核心是化繁为简，化难为易。

(三)长难句解决的具体步骤1、抓主干2、理顺主从句子关系。

(四)分析句子成分的详细过程1)找出全句主谓宾或主系表，即句子的主干;2)找出句中所有的谓语结构、非谓语结构、介词短语和从句的引导词;3)分析从句和短语的功能，例如，是否为主语从句、宾语从句、表语从句或状语从句等;以及词，短语和从句之间的关系;4)分析句子中是否有固定词组或固定搭配、插入语等其他成分第二节、长句速读同位语和较长的后置定语(如人物身份，句子中间的非限制性定语从句)，很长的专有名词(如机构名称)等。

这些信息需要用跳读(skip)的方法，略去不读。

在文章里，经常会出现此类文字信息，目的是为了干扰视线。

实际，没有必要去弄明白某人是什么大学的什么教授，也不必急着去了解美国一个部门全称或缩写是什么具体意思，因为题目中极少直接考这样的细节信息。

做题时即使需要此类信息，利用人名或其它专有名词都是开头字母大写的特征很容易找到。

例如：People assume that office politics involves some manipulative (工于心计的)behavior,”says Deborah Comer, an assistant professor of management at Hofstra University. (2004年6月)A recent study, published in last week’s Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. (2003年9月)划线部分的信息可以一扫而过，目光不需要在上面停留细读。

英语中有些句子从形式上看不包含条件从句，但在意义上却是非真实条件句，这类句子称为含蓄条件句，这样的句子可分为三类

两篇常规阅读理解和旧题型相比没有太大变化，每篇后各有5道题目，共10题，占总分值的20%.新题型的第二个大变化是增加了快速阅读部分，占总分值的10%.该题型要求学生在15分钟内通过阅读一篇长度为1200词左右的文章并完成其后的10道题目（其中前7题为正误判断，后3题为根据文章提供的信息填空）。

由此可见，新题型的阅读理解部分更加注重对学生实际阅读能力的考查，如快速阅读能力，理解文章细节的能力和在篇章中运用词汇的能力等，这也是考生在提高自己阅读能力方面应该学习的方向。

我们提出的及格要求是对于常规阅读总共20分，要达到16分以上，即每篇文章最多错1个题目，快速阅读要求7分以上。

二、阅读理解难度体现（1）阅读速度：总时间40分钟，各个题型时间被严格控制，备考训练不能忽视（2）词汇量：很多同学阅读提不上去的一个主要问题是词汇量其小（3）长句与难句：这是四级文章增加难度的方式之一（4）超迷惑性选项：增加选项难度的方式。

三、阅读理解的选材与选裁1. 选材：社会生活、经济、教育、文化、科普、等方面。

The General House EffectThe green house effect is not a new phenomenon. Scientists have known for centuries that a layer of gases naturally surrounds the earth like an insulating blanket, trapping the reflected energy of the sun and preventing it from escaping into space that is what makes the earth warm enough for people, plants and animals. However, recent human activity has boosted concentrations of greenhouse gases and enhanced their heat-trapping ability. The man culprit is carbon dioxide which scientists estimate accounts for nearly half of global warming.Co2 is released from burning fossil fuels and from clearing and burning forests.There are other important greenhouse gases too and they cannot be ignored. CFCs, for example, may account for 25 per cent of global warming in the text century if their production is not scaled back. But carbon dioxide is the pivotal one. The UN International panel on Climatic Change now says that Co2 levels could double within in 40 years if present rates of fossil-fuel burning and deforestation continue. That means an average temperature increase between two and four degrees centigrade and a sea-level rise of perhaps a foot by 2050.No one knows for certain how local weather will change as a result of this warming. But one thing is clear-it will be no picnic. Indications are that the earth will be take place not over thousands of years, but over decades. And it is the speed of the change, which makes the precise impact so difficult to predict.The most sophisticated computerized climate models in the US and UK , agree that weather around the world will become more irregular and more extreme. In general, temperatures will become more towards the poles than at the equator. overall rainfall will also increase as higher temperatures boost evaporation from the seas. But the distribution of precipitation will shift. Some areas will become wetter, others will be drier. In middle latitudes, Climate zones will march poles-wards. In tropical and subtropical parts of the third would, warming will be less but the impact on a relatively stable climate will be greater.Global warming will also cause ocean levels to rise---though not, as popular wisdom has it, due to the Antarctic ice cap melting. If this catastrophe occurs it will not be for at least another century. Instead, sea levels will rise simply because water expands as it warms. people living in low-lying coastal regions will be in danger. The world’s great river deltas, home to millions in Asia and Latin America and containing some of the Third World’s richest food-growing land, could become brackish graveyards.6. Which gas is the most responsible for global warming?A. Carbon Dioxide.B. CFCs.C. Green houses.D. other gases in the atmosphere.7. What will happen if man continues to burn fossil fuels and forests at present rates?A. All fossil fuels, like coal, oil and gas, will run out.B. Deforestation will give rise to the loss of co2.C. The temperature will increase two to four degrees Fahrenheit.D. The rise of sea-level will reach about a foot by 2050.8. Why is the precise impact the global warming will exert on local weather hard to predict?A. Because the great changes in temperature will take place in just decades.B. Because the course of changes will last thousands of years.C. Because people are not sure whether the earth will be warmer than before.D. Because there are many other factors involved in this change.9. Which of the following is true according to the passage?A. The earth, as a whole, will become much wetter.B. The temperature around equator will rise more than around the poles.C. The amount of rainfall will be the same from place to place.D. The weather around the world will be more unusual in the next few decades.10. It can be concluded thatA. The rise of ocean levels is due to the Antarctic ice cap melting.B. The temperature increase will take a gradual course.C. Human beings will have to suffer more from environmental damage.D. Without greenhouse gases the earth would be extremely hot.参考答案6.A第⼀段有这样⼀句话：the main culprit is carbon dioxide, which scientists estimate accounts for nearly half of global warming 从这句话可以看出，⼆氧化碳是全球变暖的罪魁祸⾸，对全球变暖负有重⼤责任。

Women’s Liberation one of the good things for men in women’s liberation is that men no longer have to pay women the old-fashioned courtesies. In an article on the new manners, Ms. Holmes says that a perfectly able to woman no longer has to act helplessly in public as if she were a model. For example, she doesn’t need getting in and out of cars. “Women get in and out of cars twenty times a day with babies and dogs. Surely they can get out by themselves at night just as easily.” She also says there is no reason why a man should walk on the outside of a woman on the sidewalk. “Historically, the man walked on the inside so he caught the garbage thrown out of a window. Today the man walked is supposed to walk on the outside. A man should walk where he wants to. So should a woman. If, out of love and respect, he actually wants to take the blows, he should walk on the inside- because that’s where attacks are all hiding these days. As far as manners are concerned, I suppose I have always been a supporter of women’s liberation. over the years, out of a sense of respect I imagine, I have refused to trouble women with outdated courtesies. It is usually easier to follow rules of social behavior than to depend on one’s own taste. But rules may be safely broken, of course, by those of us with the gift of natural grace. For example, when a man and woman are led to their table in a restaurant and the waiter pulls out a chair the woman is always expected to sit in the chair. That is according to Ms. Clark. I have always done it the other way according to my wife. It came up only the other night. I followed the hostess to the table, and when she pulled the chair out I sat on it quite naturally since it happened to be the chair I wanted to sit in. “Well”, said my wife when the hostess had gone. “You did it again.” “Did what?” I asked, utterly confused. “Took the chair.” Actually, since I’d walked through the restaurant ahead of my wife, it would have been awkward, I should think, not to have taken the chair. I had got there first after all. Also it has always been my custom to get in a car first and let the women get in by herself. This is a courtesy. I insist on as the stronger sex, out of love and respect. In times like these, there might be attacks hidden about. It would be unsuitable to put a woman in a car and then shut the door on her, leaving her at the mercy of some bad fellow who might be hiding in the back seat. 1. It can be concluded from the passage that____. A. men should walk on the inside of sidewalk. B. women are becoming more capable than before. C. in women’s liberation men are also liberated. D. it’s safe to break rules of social behavior 2. The author was “utterly confused” because he ___. A. took the chair out of habit. B. was trying to be polite. C. was slow in understanding.

D. he’d walked ahead of his wife. 4. The author always gets in a car before a woman because he ____. A. wants to protect her. B. doesn’t need to help her. C. chooses to be impolite to her. D. fears attacks on him. 5. Which of the following best states the main idea of the passage? A. Manners ought to be thrown away altogether. B. In manners one should follow his own judgment. C. Women no longer need to be helped in public. D. Men are not expected to be courteous to women.。
