Most American marriages, particularly first marriages 1 young couples, are the result of 2 attraction and affection 3 than practical considerations.In the United States, parents do not arrange marriages for their children. Teen-agers begin 4 in high school and usually find mates through their own academic and social 5 .Though young people feel 6 to choose their friends from 7 groups, most choose a mate of similar background. This is 8 in part to parentalguidance. Parents cannot select spouses for their children, but they can usually 9 choices by 10 disapproval of someone they consider unsuitable.11 , marriages between members of different groups (interclass, interfaith, and interracial ) occur because of the greater 12 of today's youth and thefact that hey are restricted by 13 prejudices than their parents. Many young people leave their hometowns to attend college,14 in the armed forces.15 pursue a career in a big city.Once away from home and family, they are more 16 to date and marry outside their own social group. In mobile American society, interclass marriages are neither 17 nor shocking. Interfaith marriages are 18 the rise particularly between Protestants and Catholics. On the other hand, interracial marriage is still very uncommon. I t can be difficult for interracial couples to find a place to live, maintain friendships, and 19 a family.

For each of them there are four choices marked A), B), C), and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneQuestions 1 to 5 are based on the following passage:Washington Irving was America's first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was, in fact, one of the most successful writers of his time in either country, delighting a large general public and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States. The respect in which he was held was partly owing to the man himself, with his warm friendliness, his good sense, his urbanity, his gay spirits, has artistic integrity, his love of both the Old World and the new. Thackeray described Irving as "a gentleman, who, though himself born in no very high sphere, was most finished, polished, witty; socially the equal of the most refined Europeans." In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young, uncultured nation---and he received the medal of the Royal Society of Literature; America made him ambassador to Spain.Irving's background provides little to explain his literary achievements. A gift but deliberate child, he had little schooling, He studied law, but without zeal, and never did practice seriously. He was immune to his strict Presbyterian (基督教长⽼会的) home environment, frequenting both social gatherings and the theatre.1. The main point of the first paragraph is that Washington Irving was ______.A) America's first man of lettersB) a great writer who was successful in his own country andother parts of the world as wellC) a man who won the respect of other writers because of hishigh social statusD) a man who was able to move from literature to politics2. What is implied by the comment about Scott, Poe and Hawthorne?A) Irving's great popularity resulted in the admiration of Scott, Poe andHawthorne.B) More Americans than Britains admired Irving.C) Irving's work was not only popular, but also of high literary quality.D) Irving's success was attributed to his family background.3. What can be said about Irving's law career?A) He only began to practice law late in life.B) He spent very little time working as a lawyer.C) He never practiced law although he studied it.D) He worked as a lawyer with great enthusiasm.4. Why did Thackeray think that Irving's social grace was unusual?A) Because Irving's degree was honorable and unusual.B) Because his parents were not aristocratic.C) Because he had good sense and gay spirits.D) Because he often exhibited warm friendliness.5. Which of the following best describes the effect of Irving's Presbyterian background on his life?A) It had almost no effect on his life.B) It promoted his interest in law.C) It fostered his love for literature.D) It enabled him to become a successful writer.Passage TwoQuestions 6 to 10 are based on the following passage:Psychologists now believe that noise has a considerable effect on people's attitudes and behavior. Experiments have proved that in noisy situations (even temporary ones), people be have more irritably and less cooperatively; in more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychological problems. However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels. "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for passengers at an airport who expect to hear airplanes taking off and landing, there may be a lot of sound, but not much noise (that is, they are not bothered by the noise). By contrast, if you are at a concert and two people behind you are whispering, you feel they are talking noisily even if there is not much sound. You notice the noise because it affects you psychologically. Both sound and noise can have negative effects, but what is most important is if the person has control over the sound. People walking down the street with earphones, listening to music that they enjoy, are receiving a lot of decibels of sound, but they are probably happy hearing sounds which they control. On the other hand, people in the street without earphones must tolerate a lot of noise which they have no control over. It is noise pollution that we need to control in order to help people live more happily.6. According to the passage, people _____.A) can not work better in a noisy situationB) will suffer from complete deafness because of noise pollutionC) can be psychologically affected by working in very noise factoriesD) may cooperate well in a noisy surrounding7. “Sound”, as defined by the psychologist, _____.A) can be measured in the same way that "noise" is measuredB) may be extremely harmful to healthC) is not at all different from "noise"D) can be measured by machines8. People waiting at an airport _____.A) enjoy hearing airplanes taking off and landingB) are usually not troubled by the noiseC) can easily tell sound from noiseD) are often physically affected by the noise9. People enjoy listening to music,_____.A) though they are receiving a lot of decibels of sound in factB) because it does not have any negative effectC) because they do not have to tolerate the noise around themD) even though it is sometimes unpleasant hearing strange sounds10. We can conclude from the passage that we need to control noise pollution if _____.A) we want to stay both psychologically and physically healthyB) we don't want to be physically dentC) we want to cooperate wellD) we don't want to be anxiousPassage ThreeQuestions 11 to 15 are based on the following passage:Is there a "success personality"? Some winning combination of qualities that leads almost inevitably to achievement? If so, exactly what is that secret success formula, and can anyone develop it?At the Gallop Organization we recently focused in depth on success, probing the attitudes of 1500 prominent people selected at random from Who's Who in America. Our research finds out a number of qualities that occur regularly among top achievers. Here is one of the most important, that is common sense.Common sense is the most prevailing quality possessed by our respondents. Seventy-nine percent award themselves a top score in this quality. And 61 percent say that common sense was very important in contributing to their success.To most, common sense means the ability to present sound, practical judgments on everyday affairs. To do this, one has to sweep aside extra ideas and get right to the core of what matters. A Texas oil and gas businessman puts it this way: "The key ability for success is simplifying. In conduction of meeting and dealing with industry reducing a complex problem to the simplest term is highly important."Is common sense a quality a person is born with, or can you do something to increase it? The oil man's answer is that common sense can definitely be developed. He attributes his to learning how to debate in school. Another way to increase your store of common sense is to observe it in others, learning from their and your own mistakes.Besides common sense, there are many other factors that influence success: knowing your field, self-reliance, intelligence, the ability to get things done, leadership, creativity, relationships with others, and of course, luck. But common sense standsout. If you develop these qualities, you'll succeed. And you might even find yourself listed in Who's Who someday.11. It can be known from the passage that Who's Who _____.A) is a very useful book telling us how to succeedB) is a book providing us with the information about the family life of some famouspeopleC) is a book providing us with the names and brief biographies of the top successfulpeopleD) is a book from which we can find out the names of different peoples in the world12. According to the author, common sense _____.A) is something that common people like bestB) is a popular quality a person is born withC) is something that enables one to form correct opinionsD) is a quality that is possessed by common people13. It can be inferred from the passage that a successful businessman _____.A) tries to get experience through practiceB) pays attention to the essence of a problem when he tries to solve itC) keeps on learning in order to be successfulD) has strong willpower, extensive interest and intelligence14. The passage is mainly concerned with _____.A) organizational ability and good work habitsB) the way to obtain big profits and achieve fame and successC) knowledge and interest which are primary to successD) what successful people have in common15. According to the author, how can one develop one's common sense?A) To become a businessman.B) To learn how to debate and learn from mistakes.C) To become famous.D) To be simplifying.Passage FourQuestions 1 to 5 are based on the following passage:Brazil has become one of the developing world's great successes at reducing population growth but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard.Brazil's population growth rate has dropped from 2.99 a year between 1951 and 1960 to 1.93 a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries.Martine puts it down to, among other things, soap operas and installment plans introduced in the 1970s. Both played animportant, although indirect, role in lowering the birth rate. Brazil is one of the world's biggest producers of soap operas. Global, Brazil's most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities."Although they have never really tried to work in a massage towards the problems of reproduction, they describe middle and upper class values not man children, different attitudes towards sex, women working," says Martine. "They sent his image to all parts of Brazil and made people conscious of other patterns of behavior and other values, which were put into a very attractive package."Meanwhile, the installment plans tried to encourage the poor to become consumers. "This led to an enormous change in consumption patterns and consumption was in compatible with unlimited reproduction." says Martine.16. According to the passage, Brazil has cut back its population growth _______.A) by educating its citizensB) by careful family panningC) by developing TV programmersD) by chance17. According to the passage, many Third World countries _______.A) haven't attached much importance to birth controlB) would soon join Brazil in controlling their birth rateC) haven't yet found an effective measure to control their populationD) neglected the role of TV plays in family planning18.The phrase “puts it down to” (Line 1, Para. 3) is closest in meaning to “_______”.A) attributes it toB) sums it up asC) finds it a reason forD) compares it to19. Soap operas have helped in lowering Brazil's birth rate because _______.A) they keep people sitting long hours watching TVB) they have gradually changed people's way of lifeC) people are drawn to their attractive packageD) they popularize birth control measures20.
