大学英语四级考试全真模拟试题答案解析（试卷二）Part IWriting (30 minutes)Competitions and Personal Development Nowadays, competition has almost become a natural part in every aspect of our life. On the sports ground, for example, sportsmen do their best to win the champion. In the business field, businessmen try every means to gain more profits; in school, students exert all their efforts in a race against their classmates for good marks. Competition is cruel, but does play an important part in ones personal development. Firstly, competition stimulate us to work harder. As we know we may fail if we fall behind the others, we will devote more efforts to work, which will inevitably help to improve our abilities. Secondly, competition can make us psychologically strong. Since only the fittest survive, well have to become strong to adapt to the cold competitions. Thirdly, competition strengthens the idea of equality of opportunity, so that each person has chances to display his ability. In a word, its competition that helps to bring our ability into full play.In my opinion, competition is a double-edged sword, It can sharpen ones skills and capabilities on the one hand; on the other hand it can also weigh down a person with unbearable pressure. So its important to for an individual to view competition in a constructive way, so that we can use it dynamically rather than destructively for personal development. 评析：本文段落清晰明了，并采用了总体分说的办法，先说明竞争激烈现象，列举了各个领域的竞争。第二段通过Firstly.Secondly.Thirdly. 来说明竞争对个人发展的有利因素。最后一段作者阐述了自己对竞争的观点。 整篇文章结构合理，思考周密，语言上也有很多实用的词汇。Part II Reading Comprehension (Skimming and Scanning) (15 minutes)1.答案为 N. 考生在文中可以找到“There is, of course, no single pattern of American character any more than there is a single English or Turkish or Chinese character.”句子的意思是“当然，正如英国人、土耳其人、中国人都不是只有一种性格模式一样，美国人的性格也不是单一的。”题目的意思是“和英国人、土耳其人、中国人不同的是，美国人的性格不是完全一样的。”本题与原句表述不一致。2.答案为 Y. 从题目中确定题眼attach great importance to success和dont equate success with material rewards。这两处分别对应原文的place a very high valuation upon success 和success does not necessarily mean material rewards。3.答案为 Y. 逻辑判断题。原文中提到“Therefore, material success in the United States is not looked upon as selfish.” “not selfish” 就是“not anything wrong” 的意思。4.答案为 NG. 逻辑判断题。文章以滑雪为例，表明美国人已经学会玩，而且很投入，但这并不能说明美国人最喜欢滑雪运动。5.答案为 Y. 这是对原文“But one cannot accurately call one society mature, another immature. Each has its own logic.”所做的paraphrase。题目和原句表述一致。6. 答案为 N. 细节题。从原文“American characteristics are the product of response to an unusually competitive situation combined with unusual opportunity.”一句，可以知道美国人的性格是由于特殊的竞争环境和特殊的机会而形成的。7.答案为 Y. 逻辑判断题。从文中的“no limits of class” 和 “any boy can become President”, 可以得出题目中的结论。8.答案为more time and money. 细节题。从文章中可以找到“They spend more time and money in traveling, camping, hunting, watching sports, drinking, smoking, going to movies, watching television and reading newspapers and magazines than any other people in the world.”题中的entertainment是对美国人喜欢的娱乐活动的概括。9.答案为their/the freedom. 细节题。从原文中“What is it then that makes Americans recognizable wherever they go? Free from the social restraints which would make them act very differently at home, they are bent on making the most of this freedom.”可以找到相关信息。10.答案为childish. 词汇考查题。考生要知道nave的意思，并能推断出naivety是naive的名词形式，进而找出文中nave的同义词childish。Part IIIListening Comprehension(35 minutes)11.

In a few minutes now we could be asked to fasten our seat belts and to stop smoking, and then we would soon be up in the sky on our flight to Berlin.But I had been mistaken. Ten minutes later, instead of enjoying the beauty of the evening sky from high above the clouds, I was sitting in a smoke-filled room with an airline official and a police officer at my side. On the table in front of me was one of my suitcases.The officials were very polite. They asked me to show them my passport, my ticket, and my luggage check. Then I was requested to open the suitcase and to spread out its contents on the table.I did as I was told. The moment I placed a battery-powered alarm clock I bought for my father on the table, the two officials looked at each other and smiled.Hearing the clock ticking away merrily, I suddenly understood. Someone must have heard the ticking noise coming from my suitcase and thought there was a time bomb hidden in it.26. When was the woman asked to get off the plane?27. Who inspected the woman at the office?28. Why was the woman wanted by the officials?26. 答案：B 解析：细节题。从文中Ten minutes later, instead of enjoying the beauty of the evening sky from high above the clouds, I was sitting in a smoke-filled room with an airline official and a police officer at my side.我们可以得出正确答案是B。27. 答案：D 解析：细节题。从文中I was sitting in a smoke-filled room with an airline official and a police officer at my side.我们可以得出正确答案是D。容易出现的误解是文中提到the officials对她进行检查，这里officials指the airline official和 the police officer, 但并不是the airline officials 的意思。28. 答案：A 解析：逻辑判断题。从故事的结尾倒推，可以知道该女士所携带的闹钟发出的声音引起了乘客的怀疑，才致使她被一番盘查。Passage TwoWhat does the word “library” mean to you? Do you think a library is a large, silent room containing hundreds of books? It may surprise you to learn that there are other kinds of libraries. Most libraries do lend books, but some also lend art, music, and even toys!In some libraries, you can borrow an excellent reproduction of a famous painting for your home for several weeks. Then, you can return it and bring another one home.This is also true for records. You may choose your favorite record and take it home. There you may listen to it as often as you like. Later you may return it and try something else.Toy-lending is a new idea in libraries. In a toy library childrens toys and games are classified by age groups just as books usually are. Children may play with anything in the library, and instead of demanding silence, toy libraries encourage children to make noise! Toy libraries not only provide toys and games for children, but also give them a place to meet and play with other children.29.What are some of the things that you can borrow from a library?30.What is toy-lending?31.In what kind of library can children make as much noise as they want?32.Besides toys and games, what else do toy libraries provide for children?29. 答案：D解析：细节题。从原文Most libraries do lend books, but some also lend art, music, and even toys!可知道D是正确答案。关键是考生在做听力时要养成做笔记的习惯，尤其在听到被列举的事物时。30. 答案：C 解析：逻辑判断题。从原文最后一段，我们可以看出toy-lending是图书馆提供的一种新型服务，所以C是正确答案。31. 答案：A 解析：细节题。从原文toy libraries encourage children to make noise!可知道A是正确答案。32. 答案：D解析：细节题。从原文Toy libraries not only provide toys and games for children, but also give them a place to meet and play with other children.可知道D是正确答案。另外，not only,but also也是相关信息的关键词。Passage Three“I am seventy years old,” says the gray-haired lady proudly to a man.“Did you hear that, everyone?” says the man to the people in the room. “This lovely lady is just seventy years young! And she doesnt look a day over fifty。”He has been careful not to use the word “old”. In a society where youth is so admired, old age is often seen as something sad, something to fight against. Americans prefer not to say “old people.” They use the expression “senior citizens.” They do not talk about “old peoples” homes, but “retirement” homes.In fact, the man is not so wrong. Seventy is not very old these days. People in the U.S are living longer and longer. In 1980, 12 percent of Americans were over sixty-five years old. By 2030, 21 percent will be over sixty-five. Improved medical care means that people are living longer.However, Americans are no longer happy to accept the gray hair, bald heads, and boring clothes of their own parents. American women spend millions of dollars a year on operations to lift their faces and make those ugly wrinkles disappear. Men are prepared to spend even more on operations to plant new hair on their bald heads. Its worth any money to look young.33.Why do Americans like to use the expression “senior citizen”?34.Which of these is a direct reason for Americans longer life?35.Why do Americans spend millions of dollars on their faces?33. 答案：A 解析：细节题。从原文In a society where youth is so admired, old age is often seen as something sad, something to fight against.我们可以知道美国老年人在称谓上有意回避old这个字。34. 答案：A解析：细节题。从原文Improved medical care means that people are living longer.可知道A是正确答案。35. 答案：C 解析：细节题。由原文最后一句Its worth any money to look young. 可知正确答案是C。Section C36. events37.marked38.ceremony39.affected40.differs41.celebrated42.share43.characteristics 44.
