I have kept a record of informal conversations 21 some 300 students from at 22 twenty-one colleges and universities. The students were generally frank and direct in their comments 23 how course work could be better presented. Most of their remarks were kindly made with tolerance rather than bitterness----and frequently were softened by the fact that the students were speaking about some, not all, instructors. Nevertheless, 24 the following suggestions and comments indicate, students feel 25 with things as they are in the classroom.Professors should be 26 from reading lecture notes. “It makes their voices monotonous.”If they are going to read, why not 27 out copies of the lecture? Then we wouldn’t need to go to class. Professors should 28 repeating in lectures material that is in the textbook. “29 we’ve read the material, we want to discuss it or hear it elaborated on,30 repeated.”“A lo t of students hate to buy a required text that the professor has written only to have his lectures repeat it.”21. A. counting B. covering C. figuring D. involving22. A. best B. length C. least D. large23. A. at B. on C. of D. over24. A. if B. though C. as D. whether25.

A. avoid B. prevent C. refuse D. prohibit29. A. Until B. Unless C. Once D. However30. A. not B. or C. and D. yetPart ⅢREADING COMPREHENSION ( 30 points)Directions: In this part of the tests, there are six short passages for you to read. Read the passage carefully, and then answer the questionsthat follow. Then choose the best answer from the chioces markedA, B, C and D, and mark the corresponding letter with a single bar across the square brackets on your machine-scoring AnswerSheet.Passage OneThe e-book, you could argue, is environmentally friendly, which is true, but it is also incredibly counter-intuitive. Computer engineers spend a lot of their time coming up with ways to make computers ubiquitous (无所不在的) in consumer lives, and they’ve largely succeeded in that, which is part of the point. Many consumers have also been busy rejecting electronic banking, partly because we want a few tangible experiences leftin our lives, and handling money is one of those experiences. Reading a book, in a way, is an act of rebellion today. It’s a statement that despite the 35 channels coming in on the cable box, the billions of Web sites and other diversions, you’re going to read a book. This is something someone could have done in the 16th century, when the first books were printed in English.I used to attend a regular “salon”in Man hattan, where Internet people would meet, have dinner and discuss the latest trends. One of the sponsors of these social gatherings, who worked for a publisher, brought an e-book to the group, and passed it around. Everything about it bugged me; it w as characterless, flat and soulless. One might imagine reading the works of Bill Gates on it, but the thought of reading Thackeray or Dickens or Wilkie Collins or even John Steinbeck on it is a laughing matter.In other words, books are more than just words, they have —or used to have —decorative covers, because they are expressions of the author’s creativity. That’s why some people collect first editions. They want to own the book that was authorized by the writer, an edition he or she might have owned. As books age, they attain a certain patina (古色古香), reminding of the history the object has seen.31. According to the author, one drawback of computers is that .A. they require sophisticated computer literacyB. they arc interfering with our private livesC. they can be used only in a limited numbers of areasD. they deprive us of experiences of handling things32. Today, reading books is regarded as .A. creativeB. harmfulC. intellectualD. old-fashioned33. It is the author’s opinion that .A. it is ridiculous to read literary works on an e-bookB. readers find it odd to read Bill Gates’ works on an e-bookC. reading e-books is not very different from reading paper booksD. e-books will replace traditional books in the foreseeable future34. The last paragraph is mainly concerned with the ________ aspect of paperbooks.A. physicalB. intellectualC. estheticD. historical35. What is the author’s main purpose?A. To forecast the e-books’ future.B. To make a case against e-books.C. To suggest alternatives to printed books.D. To weigh the pro and con of e-books.Passage 2Of all the areas of learning, the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people.“The burnt child fears the fire”is one instance; another is the rise of despots (暴君) like Hitler. Both these examples also point up the fact that attitudes stem from experience. In the one case the experience was direct and impressive; in the other it wasindirect and cumulative. The Nazis were indoctrinated largely by the speeches they heard and the books they read.The classroom teacher in the elementary school is in a strategic position to influence attitudes.This is true partly because children acquire attitudes from those adults whose word they respect.Another reason it is true is that pupils often delve (挖掘)somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher’s method of handling such a suit would greatly affect his attitude toward Mexicans.The media through which the teacher can develop wholesome attitudes are innumerable. Social studies (with special reference to races, creeds and nationalities), science matters of health and safety, the atmosphere of the classroom…these are a few of the fertile fields for the inculcation of properemotional reactions.However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by scolding them. She can achieve the proper effect by helping them obtain constructive experiences.To illustrate, first-grade pupils afraid of policemen will probably alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips.Finally, a teacher must constantly evaluate her own attitudes, because her influence can be deleterious if she has personalprejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of all the facts.36. The central idea conveyed in the above passage is that _______.A. attitudes affect our actionsB. teachers play a significant role in developing or changing pupils’attitudesC. attitudes can be changed by some classroom experiencesD. by their attitudes, teachers inadvertently affect pupils’ attitudes.37. A statement not made of implied in the passage is that _______.A.attitudes can be based on the learning of falsehoodsB. a child can develop in the classroom an attitude about the importanceof brushing his teethC.attitudes cannot easily be changed by rewards and lecturesD.the attitudes of elementary school-aged children are influencedprimarily by the way they were treated as infants38. The passage specifically states that _______.A.direct experiences are more valuable than indirect onesB.whatever attitudes a child learns in school have already beenintroduced at homeC.teachers should always conceal their own attitudes.D.Teachers can sometimes have an unwholesome influence on children39. The first and fourth paragraphs have all the following points in commonexcept _______.A.the importance of experience in building attitudesB.how fear sometimes governs attitudesC.how attitudes can be changed in the classroomD.how reading affects attitudes40. In the second paragraph, a substitute quotation to serve the writer’spurpose would be: _______.A.“poverty is the parent of revolution and crime.”B.“He that hath wife and children hath given hostages to fortune.C.“There is a great difference between a cunning man and a wise man.”D.“Nothing on earth consumes a man more quickly than the passion ofresentment.”Passage 3The world is undergoing tremendous changes. The rise of globalization, both economic and cultural that has swept throughout the world, has forged new ground as we enter the 21st century. But are the effects of globalization always positive? Some say no.Michael Tenet, head of the International Institute for Foreign Relations in Atlanta, is worried about current resentment throughout the world toward the rise of globalization. “Ever since the 1980s and the economic breakdown of the Asian Tigers in the late 1990s, there has been a re-evaluation of the role of globalization as a for ce for good,” he said, “Income in manycountries has declined and the gap between the most rich and the most poor has been worsened. Without further interference by governments, we could see a tragedy expressed in an increased level of poverty throughout t he Latin America and Asia.”Y et George Frank, an influential economist who works on Wall Street, sees no such danger. “E conomic liberation, increased transparency and market-based reforms have positive effect in the long run, even if market mechanism can produce short term destabilization problems,” he said. “What is most important is that barriers to trade continue to fall so that active competition for consumer goods reduces prices and in turn raises the average level of income.”Others feel that global ization’s cultural impact may be more important than its economic implications. Janice Y awee, a native of Africa, feels strongly that globalization is weakening her local culture and language. “Most of the world’s dialects will become extinct under globalization. We are paving the world with McDonald’s and English slang. It tears me up inside,” she said.However, ignoring the political dimensions of globalization has already had its cost. Nowhere was this made clearer than in the East Asian economic crisis of the late 1990s —particularly in Indonesia. In the wake of that crisis, the President Suharto’s regime was overthrown, and the entire country has been thrown into a mess. The Indonesian economy has contracted almost 50 percent, throwing tens of millions of people below the poverty line.Governments of different countries have had mixed responses to the wave of globalization. The United States is generally seen as an active proponent of greater free trade, andit certainly has enormous cultural influence by virtue of its near monopoly on worldwide entertainment. But other countries, most notably in Europe and developing nations, have sought to reduce the impact that globalization has on their domestic affairs.41. It can be inferred that Michael Tenor’s at titude toward globalization isprobably .A. strongly opposedB. cautiously agreedC. somewhat anxiousD. absolutely supportive42. According to the passage, George Frank .A. agrees with the comments made by Michael TenetB. consents the globalization is favorable to economyC. believes that the reduction of prices is due to the competitionD. thinks the instability is caused by the economic liberalization43. The words by Janice Y awee mean that .A. dialects need more protection by people in the worldB. informal English words are as popular as the McDonald's in the worldC. Janice Y awee’s local culture has vanished in the worldD. the impacts of globalization are great on cultures of the world44. The author cites the example of Indonesia in order to .A. prove the impact of globalization on the field of politicsB. show the economic crisis of the late 1990s in East AsiaC. support the successful economic and political reform in IndonesiaD. illustrate why the Suhatro’s regime collapsed45. This passage implies that .A. globalization is good for a country’s economic developmentB. globalization is widely accepted and advocated by peopleC. globalization is too influential on a country’s economy to be acceptedD. globalization is not always of great benef it to a country’s developmentPassage 4Some futurologists have assumed that the vast upsurge of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data shows that economic downturns tend to postpone marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy rebound, the number of marriages also rises.Coincident with the increasing women working outside the home is the increase in divorce rates. Y et, it may be wrong to jump to reply simple cause-and-effect conclusions. The impact of a wife’s work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible. Tensions grounded in financial problemsoften play a key role in ending a marriage. Given high unemployment, inflationary problems, and slow growth in real earnings, a working wife can increase household income and relieve some of these pressing financial burdens. By raising family’s standard of living, a working wife may strengthen her family’s financial and emotional stability.Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union.Also a major part of women’s inequality in marriage has been due to the fact that in most cases, men have remained the main breadwinner. With higher earning capacity and status occupations outside the home comes the capacity to exercise power, within the family. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities.46. The word “portend” in P aragraph 1 is closest in meaning to “________”.A. defyB. signalC. suffer fromD. result from47. It is said in the passage that when the economy slides, .A. men would choose working women as their marriage partnersB. more women would get married to seek financial securityC. even working women would worry about their marriagesD. more people would prefer to remain single for the time being48. One reason why women with no career may seek a divorce is that _ .A. they feel that they have been robbed of their freedomB. they are afraid of being bossed around by their husbandsC. they feel that their partners fall to live up to their expectationsD. they tend to suspect their husbands' loyalty to their marriage49. If women find fulfillment through work outside the home, .A. they are more likely to dominate their marriage partnersB. their husbands are expected to do more houseworkC. their marriage ties can be strengthenedD. they tend to put their career before marriage50. Which of the following statements can best summarize the author’s viewin the passage?A. The stability of marriage and the divorce rate may reflect the economicsituation of the country.B. Even when economically independent, most women have to strugglefor real equality in marriage.C. In order to secure their marriage, women should work outside the homeand remain independent.D. The impact of the growing female workforce on marriagevaries fromcase to case.Passage 5In evolutionary terms, humans are relative newcomers to earth, but in a short time they have established themselves as the most successful and dominant species. As Carl Sagan has commented, humans arrived late in December if we consider evolutionary time in terms of a calendar year. As our earliest ancestors left the forest to feed in the savannas and finally to form hunting societies on the open plains, their minds and behavior changed.The theory of natural selection provides an explanation of the evolutionary process. This theory is based on Charles Darwin’s observations of many animal species around the world. Darwin pointed out that organisms reproduce at rates that could lead to enormous increases in population sizes of most species.However, despite these massive reproductive capacities, population size tends to remain fairly constant.Darwin stressed that there is extensive variability-sometimes referred to as genetic diversity-among individuals in a species. Some of these variations appear advantageous for survival. Darwin argued that individuals characterized by these beneficial characteristics would be more likely to survive and succeed in reproducing themselves. Gradually, the organisms with the favorable characteristics would comprise a greater proportion of the population, and over a long period of time, the reproductive advantage could produce a gradual modification of the whole population. However, if environmental conditions change, new sets of characteristics might be favored and the whole process could move off in a different direction.Evolution proceeds at a very slow pace indeed. For example, the lines leading to the emergence of human beings and the great apes began to diverge about 14 million years ago. Modern man came into existence about 50, 000 years ago. The beginning of civilization as we know it began about 10, 000 years ago. In the ensuring years there have been no sweeping evolutionary changes in humans. This is not surprising because we have existed for only about 50, 000 years and it takes much longer fora mammalian species to develop.51. Which of the following statements is certain?A. Humans emerged later than most animals on earth.B. Humans came into existence when the earth was cold.C. Humans became hunters 10,000 years ago.D. No evolution has taken place in humans in the last 10,000 years.52. Why does population size remain relatively constant?A. Organisms do not reproduce at high enough rates.B. Few organisms are characterized with favorable characteristics.C. Some variations in a species fail to survive.D. Evolution takes a longer time than could be imaged.53. According to Darwin, evolution is chiefly determined by _______.A. biological factorsB. environmental factorsC. interspecies factorsD. reproduction time54. The word “diverge” in paragraph 4 is closest in meaning to “__”A. renderB. corruptC. deviateD. derive55. Evolution in a species often starts_______.A. collectivelyB. in some individualsC. suddenlyD. in a sweeping mannerPassage 6Mass production, the defining characteristic of the Second Wave economy, becomes increasingly obsolete as firms install information intens ive, often robotized manufacturing systems capable of endless deep variation, even customization, The revolutionary result is, in effect, the de-massification of mass production.The shift toward smart flex-techs promotes diversity and feeds consumer choice to the point that a Wal-Mart store can offer the buyer nearly 110,000 products in various types, sizes, models and colors to choose among.But Wal-Mart is a mass merchandiser. Increasingly, the mass market itself is breaking up into differentiated niches as customer needs diverge and better information makes it possible for businesses to identify and serve micro-markets. Specialty stores, boutiques, superstores, TV home-shopping systems, computer-based buying, direct mail and other systems provide a growing diversity of channels through which producers can distribute their wares to customers in an increasingly de-massified marketplace. When we wrote Future Shock in the late1960s, visionary marketers began talking about “market segmentation.”Today they no longer focus on “segments”buton “particles”—family units and even single individuals.Meanwhile, advertising is targeted at smaller and smaller market segments reached through increasingly de-massified media. The dramatic breakup of mass audiences is underscored by the crisis of the once great TV networks, ABC, CBS and NBC, at a time when Tele-Communications, Inc. of Denver, announces a fiber-optic network capable of providing viewers with five hundred interactive channels of television. Such systems mean that sellers will be able to target buyers with even greater precision. The simultaneous de-massification of production, distribution and communication revolutionizes the economy and shifts it from homogeneity toward extreme heterogeneity.56. What would be a proper title for this passage?A. Future ShockB. De-massificationC. Changing TrendD. Market Segmentation57. Which is true about “mass production” according to the author?A. It promotes further development in manufacturing systems.B. It defines the Second Wave economy and will last.C. It involves intensive information, automation, and customization.D. It is becoming dated for the present economy.58. The author calls those marketers “visionary” mainly because_______.A. they began talking about “market segmentation” in 1960s.B. they focus on “market particles.”。

So, it would seem that they can say, yes, it is not. But no, in fact, it is the end.A gloomy study has just been released that says that the international trend towards living alone is putting an unprecedented strain on our ecosystem.For a number of reasons---- relationship breakdown, career choice, longer life spans, smaller families---- the number of individual households is growing. And this is putting intolerable pressure on natural resources, and accelerating the extinction of endangered plant and animal species. And there is worse news. Running a refrigerator, television, cooker, plumbing system just for selfish little you is a disastrous waste of resources on our over-populated planet. “The efficiency of resource consumption” is a lot higher in households of two people or more, simply because they share everything. Well imagine that . Just when you thought living alone was OK, you would find that all the time you were the enemy of mankind. Every time you put the kettle on the stove for a cup of coffee you were destroying Mother Earth. Indeed, it is not just your mother who is a bit worried by your continuing single status ---- you are letting down the entire human race by not having a boyfriend or girlfriend. The trouble is that society has a group instinct and people panic and hit out when they see other people quietly rebelling and straying away from the “standard” of family and coupledom.The suggestion is that singledom should be at best a temporary state. Unless you are assimilated into a larger unit, you can never be fully functional.Try “communal living.” There are all these illustrations of young attractive people having a “green time,” laughingly bumping into each other. It looks like an episode of the TV series Friends.And the message is clear: Togetherness is good, solitude is bad, and being single on your own is not allowed.51. Well-meaning friends and family members often tell those who live alone that _____A they should end their singledom as soon as possible.B they should live together with other singletons.C singledom is an acceptable life-style.D singledom can shorten one’s life-span.52. Which of the following may NOT be the reason for the increasing number of households as mentioned in the passage?A Many people get divorced because of unhappy marriage.B Now people can afford to support a household individually.C Some people have to sacrifice family life for their careers.D Many people live much longer than before.53. The author thinks living alone is disastrous mainly because singledom is _________A harmful to people’s life.B destructive to our ecosystem.C dangerous to plants and animals.D unworkable in our society54. It is implied in the passage that singletons are usually _______A self-reliantB self-consciousC self-sufficientD self-centered55. When seeing others living alone, some people panic because they think singledom is ____A abnormalB diversifiedC unimaginableD disgusting56. The author suggests that singletons should ___________A find boy friends or girl friends.B live with their parents and other family members.C live together and share more with their friends.D watch more episodes of the TV series Friends.Passage TwoIn 1999 when MiShel and Carl Meissner decided to have children, they tackled the next big issue; Should they try to have a girl? It was no small matter. MiShel’s brother had become blind f rom a hereditary condition in his early 20s, and the Meissners had learned that the condition is a disorder passed from mothers to sons. If they had a boy, he would have a 50 percent chance of having the condition. A girl would be unaffected. The British c ouple’s inquiries about sex selection led them to Virginia, U.S., where a new sperm-separation technique, called MicroSort, was experimental at the time. When MiShel became pregnant she gave birth to a daughter. Now they will try to have a second daughter using the same technique.The techniques separates sperm into two groups--- those that carry the X-chromosome (染色体) producing a female baby and those that carry the Y-chromosome producing a male baby.The technology was developed in 1990s, but the opening of laboratory in January 2003 in California marked the company’s first expansion. “We believe the number of people who want this technology is greater than those who have access to it.” Said Keith L. Blauer, the company’s clinical director.This is not only a seemingly effective way to select a child’s gender. It also brings a host of ethical and practical considerations ----especially for the majority of families who use the technique for nonmedical reasons.The clinic offers sex selection for two purposes: to help couples avoid passing on a sex-linked genetic disease and to allow those who already have a child to “balance” their family by having a baby of the opposite sex.Blaucer said the company has had an impressive success rate: 91 percent of the women who become pregnant after sorting for a girl are successful, while 76 percent who sort for a boy and get pregnant are successful.The technique separates sperm based on the fact that the X chromosome is larger than the Y chromosome.A machine is used to distinguished the size differences and sort the sperm accordingly.57. Why did MiShel and Carl decide not to have a boy?A Because they might give birth to a blind baby.B Because Carl might pass his family’s disease to his son.C Because the boy might become blind when he grows up.D Because they wanted a daughter to balance their family.58. When MiShel gave birth to her first girl, the new sperm-separation technique ____A had already been well-developed.B had not been declared successful.C was available to those who wanted it.D had been widely accepted in the medical world.59. Which of the following is the author’s primary concern regarding the application of the new technology?A The expansion of the new technology may not bring profits to the companies.B Most people who use the technology will not have a baby as they want.C The effect of the new technology still needs to be carefully examined.D Increasing use of the technology may disturb the sex balance in the population60. According to Mr. Blauer, by using the new technology, ______A 91% of the women successfully give birth to girls.B 76% of the women get pregnant with boys.C it is more successful for those who want to have girls.D it is more successful for those who want to have boys.61. The sperm-separation te chnique is based on the fact that the chromosomes responsible for babies’ sex_____A are of different shapesB are of different sizesC can be identifiedD can be reproduced62. We can infer from this passage that the new technology_________A may not guarantee people a daughter or a son as they desire.B is used by most families for nonmedical reasons.C has brought an insoluble ethical dilemma for mankind.D will lead to a larger proportional of females in the population.Passage ThreeWithout question there are plenty of bargains to be had at sales time ----particularly at the top-quality shops whose reputation depends on having only the best and newest goods in stock each season. They tend, for obvious reasons, to be the fashion or seasonal goods which in due course become the biggest bargains.It is true that some goods are specially brought in for the sales but these too can provide exceptional value.A manufacturer may have the end of a range left in his hands and be glad to sell the lot off cheaply to shops; or he may have a surplus of a certain material which he is glad to make up and get rid of cheaply; or he may be prepared to produce a special line at low cost merely to keep his employees busy during slack period. He is like ly to have a good many “seconds” available and if their defects are trifling these may be particularly good bargains.Nevertheless, sales do offer a special opportunity for sharp practices and shoppers need to be extra critical. For example the “second” should be clearly marked as such and not sold as if they were perfect. The term “substandard,” incidentally, usually indicates a more serious defect than “seconds.” More serious is the habit of marking the price down from an alleged previous price which is in fact fictitious. Mis-description of this and all other kinds is much practiced by the men who run one-day sales of carpets in church halls and the like. As the sellers leave the district the day after the sale there is little possibility of redress. In advertising sales, shops may say “only 100 left” when in fact they have plenty more; conversely they may say “10,000at half-price” when only a few are available at such a drastic reduction. If ever the warning “let the buyer beware” were necessary it is during sales.63. Which kind of goods can be among the best bargains?A Cheapest goodsB Newest goodsC Seasonal goodsD Goods in stock64. The second paragraph deals with all of the following types of goods EXCEPT ____A surplus goodsB low-cost goodsC the end lot goodsD exceptionally valued goods65. In order to maintain his business during a bad time, a manufacturer may ____A have his goods produced at low cost.B sell his goods at a very low price.C have his employees sell his goods.D try to produce high quality goods.66. The passage suggests that “seconds”____________A are of better quality than “substandard goods”B attract buyers as particularly good bargains.C are defective but marked as perfect.D are goods with serious defects67. The word “redress” ( the underlined word in the last paragraph) probably means ____A dressing againB change of addressC compensation for something wrong.D selling the same product at different prices.68. During sales shoppers should ____A find the best bargains at every opportunity.B beware of being cheated.C buy things that are necessary.D pay more attention to the price.Passage FourHow many of today’s ailment, or even illnesses, are purely psychological? And how far can these be alleviated by the use of drugs? For example a psychiatrist concerned mainly with the emotional problems of old people might improve their state of mind somewhat b y the use of anti-depressants but he would not remove the root cause of their depression ----- the feeling of being useless, often unwanted and handicapped by failing physical powers.One of the most important controversies in medicine today is how far doctors, and particularly psychologists, should depend on the use of drugs for “curing” their patients. It is not merely that drugs may have been insufficiently tested and may reveal harmful side effects as happened in the case of anti-sickness pills prescribed for expectant mothers but the uneasiness of doctor who feel that they are treating the symptoms of a disease without removing the disease itself. On the other hand, some psychiatrists argue that in many cases such as chronic depressive illness it is impossible to get at the root of the illness while the patient is in a depressed state. Even prolonged psychiatric care may have no noticeable effect whereas some people can be lifted out of a depression by the use of drugs within a matter of weeks. These doctors feel not only that they have no right to withhold such treatment, but that the root cause of depression can be tackled better when the patient himself feels better. This controversy is concerned, however, with the serious psychological illnesses. It does not solve the problem of those whose headaches, indigestion, backache, etc. are due to “nerves”. Commonly a busy family doctor will ascribe them to some physical cause and as a matter of routine prescribe a drug. Once again the symptoms are being cured rather than the disease itself.It may be true to say, as one doctor suggested recently, that over half of the cases that come to the ordinary doctor’s attention are not purely physical ailments. If this is so, the situation is serious indeed.69. The author thinks that drugs used for treating psychological ills ______A could be ineffective in some cases.B usually have harmful side effects.C can greatly alleviate the illnesses.D can remove the root causes.70. The controversy mentioned in the passage focuses on ___A whether psychologists should use drugs to cure their patients.B how psychologists should treat their patients.C the fact that all of the drugs have harmful side effects.D the extent to which drugs should be used to fight psychological illness.71. The passage indicates that psychologists _____A find it impossible to remove a psychological diseaseB feel dissatisfied at treating their patients with drugs.C believe that the root cause of a disease can be ignored.D can do nothing if the patient is in a depressed state .72. When treating patients with psychological problems, some doctors feel that they ____A are at a loss for treatment.B have no right to use drugs.C have to cure their patients by any means.D should use drugs to treat the symptoms.73. A family doctor would normally consider a headache or backache as a result of ____A a more serious diseaseB some emotional problem.C a physical disorderD prolonged work74. Regarding the situation of psychological problems the author feels ____A concernedB hopelessC surprisedD disappointedPassage FiveThose who make the rules for financial institution probably should take a modified oath. Their pledge would be: First, do no harm. Second, if the reforms put before me) are unclear, don’t approve them. Charles Morris may not have intend ed his new book Money, Greed, and Risk to cast such a dim light on the regulators, but it does. In fact, it may serve as a wake-up call for true believers in our current regulatory structure, most of which was erected in the 1930s and most of which Morris seems to favor, despite the stupid results it has caused.Morris, a former Chase Manhattan banking executive, outlines in great detail, again and again, how regulators, lawmakers, firms and many of the customers marched straight into mortgage, currency, thrift (互相储蓄) and other investment disasters. His discussion of Regulation Q, an attempt by Congress in the 1960s to rescue ailing savings and loans by regulating interest rates, reveals not only Congressional economic illiteracy, but also the deep harm such foolish thinking can do to the real economy.After some 260 pages listing the foolish things of Wall Street, regulators and lawmakers, Morris draws some pessimistic conclusions: “One constant in all the crises is that the regulatory responses come only after a crisis hits its peak.” For example, it “took the S&L crisis of the 1980s to bring honest accounting to thrifts, and it wasn’t until the banking sector suffered huge losses in real estate and foreign loans that regulators began to enforce strict capital standards.”So, what is the point of regulation? Morris, who is excellent at recounting tales of regulation gone bad, asserts that regulation is absolutely necessary, that it is the essential plumbing in our economic house. Nevertheless, Mr. Morris should have noticed that plumbing requires plumbers, and while a good one can keep a house functional, a rotten plumber can turn a minor drip into a ruinous flood.75. The passage is primarily concerned with ___A recommending Morris’s new book.B criticizing Morris’ attitude to regulations.C describing current economic situations.D commenting on financial regulators.76. Which of the following is true of Money, Greed and Risk?A It discusses the importance of plumbing in keeping a house functional.B It describes a great number of financial disasters in detail .C It analyses the reasons for regulating the banking industry.D It emphasizes the flaws in the financial system of the 1930s.77. Regulation Q is quoted in the passage mainly to ____A demonstrate what kind of examples Morris has cited in his book.B illustrate that misguided policies can be very harmful to economy.C support Morris’s statement about the incompetence of Congressmen and bankers.D refute Morris’s conclusion a bout the foolishness of the government regulations.78. The government regulations often fail to bring the desired result partly because ____A the regulators do not understand economy well.B the regulations are enforced before a crisis hits its peak.C banking executives do not believe in the current regulatory structure.D the standards for financial institutions are not consistent.79. According to the passage, which of the following is true of Morris?A He needn’t have recounted so many financ ial disasters.B He has little faith in the present-day regulatory system.C He has failed to point out that regulators are more to blame than unwise regulations.D His book will undermine the readers’ faith in the current regulatory structure.80. T he author’s attitude towards Morris’s new book can best be described as ____A scornfulB appreciativeC satiricalD criticalPart V Translation (30 minutes, 20 points)What’s strange about man is that he has yet to learn to settle disputes by som e means other than war. Not only does war take a heavy toll of lives, but leads to increased tension. The use of sophisticated weapons is apt to bring about disasters to human health, although the reluctance to eliminate weapons of mass destruction on the part of the big powers will not necessarily end up with conflicts. The chances are that man will have his own civilization destroyed if the notion of the survival of the fittest still applies to the international community. We can’t help wondering how man y years it will take for the world to eliminate war once for all.运用世界领先的技术将使中国有可能摆脱贫穷。

So, it would seem that they can say, yes, it is not. But no, in fact, it is the end.A gloomy study has just been released that says that the international trend towards living alone is putting an unprecedented strain on our ecosystem.For a number of reasons---- relationship breakdown, career choice, longer life spans, smaller families---- the number ofindividual households is growing. And this is putting intolerable pressure on natural resources, and accelerating the extinction of endangered plant and animal species. And there is worse news. Running a refrigerator, television, cooker, plumbing system just for selfish little you is a disastrous waste of resources on our over-populated planet. “The efficiency of resource consumption” is a lot higher in households of two people or more, simply because they share everything. Well imagine that . Just when you thought living alone was OK, you would find that all the time you were the enemy of mankind. Every time you put the kettle on the stove for a cup of coffee you were destroying Mother Earth. Indeed, it is not just your mother who is a bit worried by your continuing single status ---- you are letting down the entire human race by not having a boyfriend or girlfriend. The trouble is that society has a group instinct and people panic and hit out when they see other people quietly rebelling and straying away from the “standard” of family and coupledom.The suggestion is that singledom should be at best a temporary state. Unless you are assimilated into a larger unit, you can never be fully functional.Try “communal living.” There are all these illustrations of young attractive people having a “green time,” la ughingly bumping into each other. It looks like an episode of the TV series Friends.And the message is clear: Togetherness is good, solitude is bad, and being single on your own is not allowed.51. Well-meaning friends and family members often tell those who live alone that _____A they should end their singledom as soon as possible.B they should live together with other singletons.C singledom is an acceptable life-style.D singledom can shorten one’s life-span.52. Which of the following may NOT be the reason for the increasing number of households as mentioned in the passage?A Many people get divorced because of unhappy marriage.B Now people can afford to support a household individually.C Some people have to sacrifice family life for their careers.D Many people live much longer than before.53. The author thinks living alone is disastrous mainly because singledom is _________A harmful to people’s life.B destructive to our ecosystem.C dangerous to plants and animals.D unworkable in our society54. It is implied in the passage that singletons are usually _______A self-reliantB self-consciousC self-sufficientD self-centered55. When seeing others living alone, some people panic because they think singledom is ____A abnormalB diversifiedC unimaginableD disgusting56. The author suggests that singletons should ___________A find boy friends or girl friends.B live with their parents and other family members.C live together and share more with their friends.D watch more episodes of the TV series Friends.Passage TwoIn 1999 when MiShel and Carl Meissner decided to have children, they tackled the next big issue; Should they try to have a girl? It was no small matter. MiShel’s brother had become blind f rom a hereditary condition in his early 20s, and the Meissners had learned that the condition is a disorder passed from mothers to sons. If they had a boy, he would have a 50 percent chance of having the condition. A girl would be unaffected. The British c ouple’s inquiries about sex selection led them to Virginia, U.S., where a new sperm-separation technique, called MicroSort, was experimental at the time. When MiShel became pregnant she gave birth to a daughter. Now they will try to have a second daughter using the same technique.The techniques separates sperm into two groups--- those that carry the X-chromosome (染色体) producing a female baby and those that carry the Y-chromosome producing a male baby.The technology was developed in 1990s, but the opening of laboratory in January 2003 in Califor nia marked the company’s first expansion. “We believe the number of people who want this technology is greater than those who have access to it.” Said Keith L. Blauer, the company’s clinical director.This is not only a seemingly effective way to select a child’s gender. It also brings a host of ethical and practical considerations ----especially for the majority of families who use the technique for nonmedical reasons.The clinic offers sex selection for two purposes: to help couples avoid passing on a sex-linked genetic disease and to allow those who already have a child to “balance” their family by having a baby of the opposite sex.Blaucer said the company has had an impressive success rate:91 percent of the women who become pregnant after sorting fora girl are successful, while 76 percent who sort for a boy and get pregnant are successful.The technique separates sperm based on the fact that the X chromosome is larger than the Y chromosome.A machine is used to distinguished the size differences and sort the sperm accordingly.57. Why did MiShel and Carl decide not to have a boy?A Because they might give birth to a blind baby.B Because Carl might pass his family’s disease to his son.C Because the boy might become blind when he grows up.D Because they wanted a daughter to balance their family.58. When MiShel gave birth to her first girl, the new sperm-separation technique ____A had already been well-developed.B had not been declared successful.C was available to those who wanted it.D had been widely accepted in the medical world.59. Which of the following is the author’s primary concern regarding the application of the new technology?A The expansion of the new technology may not bring profits to the companies.B Most people who use the technology will not have a baby as they want.C The effect of the new technology still needs to be carefully examined.D Increasing use of the technology may disturb the sex balance in the population60. According to Mr. Blauer, by using the new technology,______A 91% of the women successfully give birth to girls.B 76% of the women get pregnant with boys.C it is more successful for those who want to have girls.D it is more successful for those who want to have boys.61. The sperm-separation te chnique is based on the fact that the chromosomes responsible for babies’ sex_____A are of different shapesB are of different sizesC can be identifiedD can be reproduced62. We can infer from this passage that the new technology_________A may not guarantee people a daughter or a son as they desire.B is used by most families for nonmedical reasons.C has brought an insoluble ethical dilemma for mankind.D will lead to a larger proportional of females in the population.Passage ThreeWithout question there are plenty of bargains to be had at sales time ----particularly at the top-quality shops whose reputation depends on having only the best and newest goods in stock each season. They tend, for obvious reasons, to be the fashion or seasonal goods which in due course become the biggest bargains.It is true that some goods are specially brought in for the sales but these too can provide exceptional value.A manufacturer may have the end of a range left in his hands and be glad to sell the lot off cheaply to shops; or he may have asurplus of a certain material which he is glad to make up and get rid of cheaply; or he may be prepared to produce a special line at low cost merely to keep his employees busy during slack period. He is like ly to have a good many “seconds” avai lable and if their defects are trifling these may be particularly good bargains.Nevertheless, sales do offer a special opportunity for sharp practices and shoppers need to be extra critical. For example the “second” should be clearly marked as such and no t sold as if they were perfect. The term “substandard,” incidentally, usually indicates a more serious defect than “seconds.” More serious is the habit of marking the price down from an alleged previous price which is in fact fictitious. Mis-description of this and all other kinds is much practiced by the men who run one-day sales of carpets in church halls and the like. As the sellers leave the district the day after the sale there is little possibility of redress. In advertising sales, shops may say “only100 left” when in fact they have plenty more; conversely they may say “10,000 at half-price” when only a few are available at such a drastic reduction. If ever the warning “let the buyer beware” were necessary it is during sales.63. Which kind of goods can be among the best bargains?A Cheapest goodsB Newest goodsC Seasonal goodsD Goods in stock64. The second paragraph deals with all of the following types of goods EXCEPT ____A surplus goodsB low-cost goodsC the end lot goodsD exceptionally valued goods65. In order to maintain his business during a bad time, a manufacturer may ____A have his goods produced at low cost.B sell his goods at a very low price.C have his employees sell his goods.D try to produce high quality goods.66. The passage s uggests that “seconds”____________A are of better quality than “substandard goods”B attract buyers as particularly good bargains.C are defective but marked as perfect.D are goods with serious defects67. The word “redress” ( the underlined word in the last paragraph) probably means ____A dressing againB change of addressC compensation for something wrong.D selling the same product at different prices.68. During sales shoppers should ____A find the best bargains at every opportunity.B beware of being cheated.C buy things that are necessary.D pay more attention to the price.Passage FourHow many of today’s ailment, or even illnesses, are purely psychological? And how far can these be alleviated by the use of drugs? For example a psychiatrist concerned mainly with the emotional problems of old people might improve their state of mind somewhat b y the use of anti-depressants but he would not remove the root cause of their depression ----- the feeling ofbeing useless, often unwanted and handicapped by failing physical powers.One of the most important controversies in medicine today is how far doctors, and particularly psychologists, should depend on the use of drugs for “curing” their patients. It is not merely that drugs may have been insufficiently tested and may reveal harmful side effects as happened in the case of anti-sickness pills prescribed for expectant mothers but the uneasiness of doctor who feel that they are treating the symptoms of a disease without removing the disease itself. On the other hand, some psychiatrists argue that in many cases such as chronic depressive illness it is impossible to get at the root of the illness while the patient is in a depressed state. Even prolonged psychiatric care may have no noticeable effect whereas some people can be lifted out of a depression by the use of drugs within a matter of weeks. These doctors feel not only that they have no right to withhold such treatment, but that the root cause of depression can be tackled better when the patient himself feels better. This controversy is concerned, however, with the serious psychological illnesses. It does not solve the problem of those whose headaches, indigestion, backache, etc. are due to “nerves”. Commonly a busy family doctor will ascribe them to some physical cause and as a matter of routine prescribe a drug. Once again the symptoms are being cured rather than the disease itself.It may be true to say, as one doctor suggested recently, that over half of the cases that come to the ordinary doctor’s attention are not purely physical ailments. If this is so, the situation is serious indeed.69. The author thinks that drugs used for treatingpsychological ills ______A could be ineffective in some cases.B usually have harmful side effects.C can greatly alleviate the illnesses.D can remove the root causes.70. The controversy mentioned in the passage focuses on ___A whether psychologists should use drugs to cure their patients.B how psychologists should treat their patients.C the fact that all of the drugs have harmful side effects.D the extent to which drugs should be used to fight psychological illness.71. The passage indicates that psychologists _____A find it impossible to remove a psychological diseaseB feel dissatisfied at treating their patients with drugs.C believe that the root cause of a disease can be ignored.D can do nothing if the patient is in a depressed state .72. When treating patients with psychological problems, some doctors feel that they ____A are at a loss for treatment.B have no right to use drugs.C have to cure their patients by any means.D should use drugs to treat the symptoms.73. A family doctor would normally consider a headache or backache as a result of ____A a more serious diseaseB some emotional problem.C a physical disorderD prolonged work74. Regarding the situation of psychological problems theauthor feels ____A concernedB hopelessC surprisedD disappointedPassage FiveThose who make the rules for financial institution probably should take a modified oath. Their pledge would be: First, do no harm. Second, if the reforms put before me) are unclear, don’t approve them. Charles Morris may not have intend ed his new book Money, Greed, and Risk to cast such a dim light on the regulators, but it does. In fact, it may serve as a wake-up call for true believers in our current regulatory structure, most of which was erected in the 1930s and most of which Morris seems to favor, despite the stupid results it has caused.Morris, a former Chase Manhattan banking executive, outlines in great detail, again and again, how regulators, lawmakers, firms and many of the customers marched straight into mortgage, currency, thrift (互相储蓄) and other investment disasters. His discussion of Regulation Q, an attempt by Congress in the 1960s to rescue ailing savings and loans by regulating interest rates, reveals not only Congressional economic illiteracy, but also the deep harm such foolish thinking can do to the real economy.After some 260 pages listing the foolish things of Wall Street, regulators and lawmakers, Morris draws some pessimistic conclusions: “One constant in all the crises is that the regulatory responses come only after a crisis hits its peak.” For example, it “took the S&L crisis of the 1980s to bring honest accou nting to thrifts, and it wasn’t until the banking sector suffered hugelosses in real estate and foreign loans that regulators began to enforce strict capital standards.”So, what is the point of regulation? Morris, who is excellent at recounting tales of regulation gone bad, asserts that regulation is absolutely necessary, that it is the essential plumbing in our economic house. Nevertheless, Mr. Morris should have noticed that plumbing requires plumbers, and while a good one can keep a house functional, a rotten plumber can turn a minor drip into a ruinous flood.75. The passage is primarily concerned with ___A recommending Morris’s new book.B criticizing Morris’ attitude to regulations.C describing current economic situations.D commenting on financial regulators.76. Which of the following is true of Money, Greed and Risk?A It discusses the importance of plumbing in keeping a house functional.B It describes a great number of financial disasters in detail .C It analyses the reasons for regulating the banking industry.D It emphasizes the flaws in the financial system of the 1930s.77. Regulation Q is quoted in the passage mainly to ____A demonstrate what kind of examples Morris has cited in his book.B illustrate that misguided policies can be very harmful to economy.C support Morris’s statement about the incompetence of Congressmen and bankers.D refute Morris’s conclusion a bout the foolishness of the government regulations.78. The government regulations often fail to bring thedesired result partly because ____A the regulators do not understand economy well.B the regulations are enforced before a crisis hits its peak.C banking executives do not believe in the current regulatory structure.D the standards for financial institutions are not consistent.79. According to the passage, which of the following is true of Morris?A He needn’t have recounted so many financ ial disasters.B He has little faith in the present-day regulatory system.C He has failed to point out that regulators are more to blame than unwise regulations.D His book will undermine the readers’ faith in the current regulatory structure.80. T he author’s attitude towards Morris’s new book can best be described as ____A scornfulB appreciativeC satiricalD criticalPart V Translation (30 minutes, 20 points)What’s strange about man is that he has yet to learn to settle disputes by som e means other than war. Not only does war take a heavy toll of lives, but leads to increased tension. The use of sophisticated weapons is apt to bring about disasters to human health, although the reluctance to eliminate weapons of mass destruction on the part of the big powers will not necessarily end up with conflicts. The chances are that man will have his own civilization destroyed if the notion of the survival of the fittest still applies to the international community.

A Simple Circular-to-Rectangular Waveguide TransitionEric L. Holzman, Senior Member, IEEEAbstract —We describe a novel one-step 11T E -mode circular waveguide to 10T E -mode rectangular waveguide transition. The primary advantage of this device over existing transitions is its ease of fabrication. We have incorporated our transition into a number of waveguide components operating at V-band. The transition’s measured return loss exceeds 15 dB over a 12% bandwidth c entered near 60 GHz.Index Terms —Circular waveguides, rectangular waveguides, waveguide junctions, waveguide transitions, waveguides.Ⅰ. INTRODUCTION①TRANSITIONS between metal electromagnetic waveguides of different cross sections are probably nearly as old as waveguides themselves. ②In particular, horn and reflector antennas often use circular waveguide feeds but require more standard rectangular waveguide for connection to the rest of the microwave system. ③A variety of methods exist for transforming between a circular waveguide propagating the 11T E mode and a rectangular waveguide propagating the mode. A gradualtransition, in which the rectangular cross section is transformed continuously over the length of the transition into a circular cross section, provides very low insertion loss and high return loss over a broad bandwidth, but is relatively long. ④The bandwidth of a stepped transition, in which the rectangular waveguide is matched to the circular waveguide via one or more intermediate structures of constant cross section, increases with the number of steps [1]–[5]. We also can butt the rectangular and circularwaveguides directly together with an iris at the junction for matching [6]. ⑤All these structures require a significant amount of precision machining, especially in the millimeter-wave bands, where the waveguide dimensions are small.We describe a simple, easy-to-implement, one-step transition for dominant mode circular to rectangular waveguide. ⑥The transition requires a single machining operation to fabricate. Our design appears to be novel.Ⅱ. CONCEPT⑦Fig. 1 shows a conventional one-step circular-to-rectangular waveguide transition, much like that described in [5]. Typically, the step is the output of the component with the circular waveguide. ⑧The circular waveguide has a diameter that is greater than the height of standard rectangular waveguide if we are to operate at least 10% above the 11T E mode cutoff frequency. ⑨Thus, to machine a one-step transition out of a block of metal, the circular waveguide is drilled from one end a precisely controlled depth, leaving exactly enough distance to machine the transition step from the other end of the block.Ourtransition, shownin Fig. 2, is much simpler to fabricate. We drill the circular waveguide completely through the metal block fromeitherside. Then we machine the transition slot to the desired end of the block in a single operation. ⑩This transitioncan even be addedasan“after-thought” to structures that were created without one.⑪Because the circular waveguide diameter is greater than the step height, the transition cross-sectional structure is a complex shape, perturbed by the circular waveguide as shown in Fig. 2(b). However, with available three-dimensional(3-D) numericalelec- tromagnetic simulators and optimizers, we easily can select the transition length and cross-sectional dimensions for the optimum impedance match and lowest insertion loss.The transition in Fig. 2 is sized to operate from 57 to 64 GHz.⑫ For this frequency range, we use WR-15 rectangular waveguide,0.148 in wide and 0.074 in high with aT E mode cutoff frequency of 39.9 GHz. ⑬Full radius WR-15 waveguide, shown in 10Fig. 2(a), is easier to machine, and its width of 164 mils makes it electrically equivalent to the standard waveguide. Our transition will operate with either waveguide. The circular waveguide has aT E mode cutoff frequency of 49.1 GHz.11⑭The next higher order mode, theT M mode, cuts off at 64.1 GHz.01Ⅲ. PERFORMANCEWe have built many of the V-band transitions shown in Fig. 2 and used them on horn antennas, transmitters, and receivers. Fig. 3 shows a photograph of an actual transition. We used computer simulation technology’s (CST) microwave studio to de- sign and analyze the transition, and the predicted and measured input match are shown in Fig. 4. In addition, the predicted performance of a conventional one-step transition (see Fig. 1) is shown for comparison. We measured the transition’s return loss with a WR-15 scalar analyzer. The test fixture consisted of a well-matched circular waveguide horn with the transition machined at its input. We loaded the horn with a crude taper made from foam absorber. The transition’s measured return loss is greater than 15 dB over a 12% bandwidth centered near 60 GHz. The frequency shift of the return loss maximum and overall decrease in return loss are caused by our imperfect V-band load.⑮To understand the impact of machining tolerances better, we performed some tolerance analyses with our simulation software. We observed a roughly 200-MHz change in passband center frequency per 0.001-in change in slot height. The center frequency changed about half as much per 0.001-in change in slot width. In both cases, there was essentially no change to the depth of the return loss null at the band center. ⑯The most sensitive dimension is the depth of the slot, which shifts the passband about 250 MHz higher per 0.001-in decrease.Because higher order rectangular waveguide modes are above cutoff within the slot transition, and the circular waveguideT M propagates above 64 GHz, we01performed simulations to study E- and H-plane misalignment of the WR-15 waveguide relative to the slot transition and circular waveguide, which were kept perfectly aligned. Misalignment along the H-plane (width of slot) slightly perturbs the center frequency of the passband, about 70 MHz increase per 0.001-in offset. Mis-alignment in the E-plane is more deleterious, with the primary effect being the occurance of a low return loss resonance at 59.3 GHz. WR-15 waveguides are precision aligned with dowel pins, and with these in place we observed no resonance in our measurement (see Fig. 4). However, when we removed the dowel pins and intentionally misaligned the transition and WR-15 test waveguide, we measured the resonance in the return loss at 58.9 GHz.Ⅳ.CONCLUSIONWe have described a novel, single-step, simple to fabricate circular waveguide to rectangular waveguide transition. The transition has the same bandwidth as a conventional single-step transition. It requires a single machining operation to construct and can be added as an “after-thought” to structures that were created without a transition.REFERENCES[1]G. Spinner and L.

In the past, interspecies hybridization was dismissed as a possible solution, since hybrids are rarely as vigorous as purebred species. However, current research on hybridization suggests that although some hybrids are not as virile as either of the parent species, they are often strong enough to pass their traits on. Scientists have also found hybrid species, such as certain types of corn, that are stronger than their parent species, a phenomenon known as “hybrid vigor”. These findings suggest that hybridization plays a far more important role in evolution than previously suspected.41. It can be inferred that some scientists previously believed that ________.A. the details of evolutionary theory may never be fully understoodB. hybrid plants lack the ability to reproduce by themselvesC. plants that are robust possess an evolutionary advantageD. purebred plants play a relatively minor role in evolution42. The passage implies that most scientists will adopt a theory that ________.A. includes elements about which little is knownB. cannot be proven by experimental meansC. involves ideas which will likely be disproved laterD. has limited real-world applications2Though most people know the definition of the word “boycott”, few know its origin. Named for Captain Charles Boycott, the word as we know it owes less to him than to Irish nationalist Charles Parnell. Parnell organized Irish farmers and convinced them to fix their rent rates. When Boycott refused, Parnell unleashed the power of the people. A band of hostile peasants forced the Captain’s servants to leave. There were no laborers to gather the harvest and no stablemen to ca re for the animals. Boycott was not allowed to enter stores or make purchases. Eventually, Boycott and his wife fled Ireland, and Parnell was hailed as the workingman’s hero.43. The passage is best summarized by which of the following?A. The origin of a word is explored, and an explanation for its popularity is given.B. A word is introduced, and a history of its usage is related.C. An event is described as the reason behind a shift in a word’s meaningD.A word is introduced, and the history of its coining is related.44. It can be most reasonably inferred from the passage that _______.A. Boycott’s land was not harvested that yearB. the townspeople referred to were sympathetic to the farmersC. Parnell was popular among all IrishmenD. the farmers threatened Boycott with physical harm3Passage 1:No major political election in the United States has ever been decided by one vote. In fact, a single vote contributes only about one millionth of the total result of the average statewide election. Considering how numerically insignificant a single vote is, is there any rational justification for an individual to vote? In order to answer this question, one must look past the mere numerical value of a vote. An individual’s vote is valuable as a measure of that individual’s belief in the system of government, which likewise indicates the degree to which a person feels included in the greater social order.Passage 2:When recently asked whom he voted for in the last presidential election, a friend of mine replied, “I didn’t bother.” With a rather bored shrug, and little embarrassment, my friend continued, “I t’s not like it matters. My vote wouldn’t have changed the outcome.” I couldn’t help thinking then that the argument was uncannily persuasive. If I had stayed in bed that morning, the result would likewise be exactly the same. But the argument does not hold up under scrutiny. If democracy means rule by the people, and not by any one individual, then why should the vote of just one person determine the outcome of an election? No person, no matter who he is, should be able to change the greater will of a collected group. The idea of doing so is simply undemocratic.45. Which of the following, if true, would most strengthen the hypothesis of the author of Passage1 concerning voting behavior?A. Historical documents reveal that may local elections have been decided by a single vote. B．A new study finds that many Americans feel that voting is a burdensome inconvenience. C．A poll of American citizens indicates that most citizens consider voting an important communal duty.D．V oting records show that most people who vote participate in both national and local elections.46. The author of Passage 1 would most likely conclude which of the following about the “friend”described in Passage 2?A. The friend likely feels that he is disconnected from the society in which he lives. B．Unless he changes the outcome of an election, the friend is unlikely to ever vote.C. The number of people today who act as the friend does indicates a fundamental flaw in society.D．People who don’t feel the need to vote are generally satisfied with life as it is.47. Both passages serve to discourage the ________.A．inclination of Americans to invent excuses for not votingB．tendency of voters to avoid making difficult decisionsC．valuation of a vote by its ability to decide an electionD．apathy that some voters feel about the lack of real choices48. The final sentence of Passage 2 serves to ________.A．explain the rationale behind a behavior patternB．denounce the actions of those who do not voteC．show the subtle irony of the friend’s argumentD．offer a solution to a pressing problem41 Laboratory research is at the heart of scientific life; scientists’ real work consists of testing out ideas that come to them as they ponder the mysteries of the world around them. A natural biologist walks through a city park or across a suburban lawn and is half-consciously wondering: Why two leaves instead of three? Why pink flowers instead of white? Such rumination goes on without end in a scientist’s mind, a continuous accompaniment to the rhythm of daily life. Whatever a scientist is doing—reading, cooking, talking, playing—science thoughts are always there at the edge of the mind. They are the way the world is taken in; all that is seen is filtered through an ever present scientific musing.2 How a would-be scientist decides on a discipline, settles on a problem, and goes to work is often as much a mailer of chance as it is of temperament. One can easily become a chemist or a neuroanatomist because of where one went to school or whose influence one happened to come under as because of a compelling early response to the logic of chemistry or the beauty of the human nervous system. No matter. Once the discipline is established, the problem chosen, and the scientist immersed in the work, he or she becomes as persuaded as need be of the centrality and urgency of the particular work being done. Such adaptive myopia is necessary in science because the grinding, repetitive minuteness of daily laboratory work is so time-consuming (for weeks, months, even years at a time) that, often, even to remember the original impetus for the work is a psychological trick of the highest order. To stimulate the memory back into existence with fair regularity, one must believe in the fundamental importance of what one is doing. Those who do are the most energetic, vital, exciting, and excited of scientists.3 Carol Steiner, a geneticist, comes up with a fine metaphor for how to make a working proposition of scientific mystery. “Imagine,” she says, “that you have a jigsaw puzzle with no picture printed on it. All you have are pieces you haven’t a clue how to make sense of. The pieces are your separate scientific observations. Here’s an e xample of how you might try to get a handle on the puzzle:4 “We have a microorganism with a secretory structure on one end. We know this structure is always on the same place in the cell and that the position of this structure is inherited. The question we want to answer is, how can inherited information be translated into positional information? Why in that one place and no place else? Is the genetic code involved, and if so, how? The answer will tell us how the genes work in concert with the rest of the cell to put things where they belong.5 “In order to gather pieces of the jigsaw puzzle (that is, pieces of information), we poke at the cell. We change it a little … . A specific mutation that altered the membrane structure of the cell was found to turn off the synthesis of the secretory structure. This was a piece of the jigsaw puzzle. But just one piece. Because we hadn’t a clue as to how this had happened or could happen.” Steiner indicates that there will be many further questions that will suggest experiments whose results may allow us to print pictures on the pieces of the jigsaw puzzle: “Not put the puzzle together, mind you. But help us think about what the picture will ultimately look like.”6 The realized picture on Carol Steiner’s jigsaw puzzle i s the map of gene expression laid out clearly with all roads, pathways, connecting signal points, and railway junctions marked so that any tourist can find his or her way in this beautiful country, which is confusing only when one is wandering about in ignorance—as we all are now—with a highly incomplete map.49. The primary purpose of the passage is to convey information about the ________.A. occupational hazards encountered by laboratory workers.B. problem-solving skills taught by chemists and neuroanatomistsC. professional collaboration necessary for geneticistsD. thought processes distinctive to research scientists50. In Line 1, the author characterizes “laboratory research” as something that is________.A. fundamentalB. ambitiousC. challengingD. time-consuming51. The author indicates that the process of “rumination” (paragraph 1) is________.A. subjectiveB. vexatiousC. incessantD. innovative52. In paragraph 2, “No matter” dismisses as irrelevant the means by which________.A. science students learn research skillsB. scientists choose research specialtiesC. laboratory reports explain methodologiesD. scientific knowledge is perceived by the public53. The “memory” referred to in paragraph 2 is that of the ________.A. initial fascination with a scientific goalB. steps required to establish scientific truthC. day-to-day repetitiveness of the workD. relevant training in the academic field54. The passage implies that the discovery of the “specific mutation”(paragraph 5) was most significant for________.A. demonstrating the random nature of scientific breakthroughsB. proving that multiple factors affect microorganismsC. providing a clue to the solution of a research questionD. justifying the expense of a major research project55. Which b est describes the function of Steiner’s account of her research in the overall development of the passage?A. A digression from the author’s central argumentB. A refutation of criticisms raised earlier in the passageC. An observation that challenges previous assertionsD. An example that expands upon preceding generalization51 The downslope movement of rock, mud, or other material under the influence of gravity is known as mass wasting. While the angle of the slope is a major factor in the potential for mass wasting, the slope is not the sole determiner of mass wasting events. Water plays a significant role, especially where it is plentiful during the rainy season. Earthquakes may cause rockslides, mudflows, and other mass movements. Factors such as the presence or absence of vegetation andhuman activities can also influence the potential for mass wasting.2 One way to classify mass wasting processes is on the basis of the material involved, such as rock, debris, earth, or mud. The manner in which the material moves is also important and is generally described as a fall, a slide, or a flow. A fall occurs when weathering loosens boulders from cliffs or rock faces, causing the boulders to break away and fall. A slide takes place whenever material remains fairly coherent and moves along a well-defined surface. A flow involves the movement of debris containing a large amount of water.3 Many mass wasting processes are described as slides. Rockslides occur when a coherent mass of rock breaks loose and slides down a slope as a unit. If the material involved is mostly separate pieces, it is called a debris slide. Slides are among the fastest and most destructive mass movements. Usually rockslides occur in a geologic setting where the rock layers are inclined, or where there are joints and fractures in the rock that are parallel to the slope. When such a rock unit is undercut at the base of the slope, it loses support and the rock eventually collapses. Rain or snowmelt can trigger a rockslide by wetting the underlying surface to the point that friction can no longer hold the rock in place. The fastest type of slide is a rock avalanche, in which a mass of rock literally floats on air as it moves downslope. The high speed of a rock avalanche is the result of air becoming trapped and compressed beneath the falling mass of debris, allowing it to move down the slope as a buoyant sheet.4 Mudflows are relatively rapid mass wasting events that involve soil and a large amount of water. Because of their fluid properties, mudflows follow canyons and stream channels. Mudflows often take place in semiarid mountainous regions and on the slopes of some volcanoes. Although rainstorms in semiarid regions are infrequent, they are typically heavy when they occur. When a rainstorm or rapidly melting snow creates a sudden flood, large quantities of soil and loose rock are washed into nearby stream channels because there is usually little or no vegetation to anchor the surface material. The result is a flowing mass of well-mixed mud, soil, rock, and water. The consistency of the mudflow may be similar to that of wet concrete, or it may be a soupy mixture not much thicker than muddy water. The water content influences the rate of flow across the surface. When a mudflow is dense, it moves more slowly, but it can easily carry or push large boulders, trees, and even houses along with it.5 In dry mountainous areas such as southern California, mudflows are a serious hazard to development on and near canyon hillsides. The removal of native vegetation by brush fires has increased the probability of these destructive events.Past mudflows have contributed to the buildup of fan-shaped deposits at canyon mouths. Such fans are relatively easy to build on and often have scenic views, so many have become desirable sites for residential development. However, because mudflows occur infrequently, homeowners are often unaware of the potential danger of building on the site of a previous mudflow.6 Highly fluid, fast-flowing mudflows incorporate fine-grained sediment and are common after volcanic eruptions that produce large volumes of volcanic ash. Mudflows containing volcanic debris are called lahars, a word originating in Indonesia, a region that experiences many volcanic eruptions. Lahars occur when highly unstable layers of ash and debris become saturated with water and flow down steep volcanic slopes along stream channels. In the northwestern United States, the eruption of Mount St. Helens in 1980 created several lahars that raced down the valley of the Toutle River, altering the landscape in a relatively short period.56. All of the following are given as factors in mass wasting EXCEPT ________.A．the angle of the slopeB．the presence of waterC．the absence of plantsD．the type of mineral57. The name of a mass wasting process is a reflection of ________.A．the area in which the movement occursB．the material that is moved and the way it movesC．the rate of movement relative to other processesD．the mass and volume of the material involved58. The word “trigger” in paragraph 3 is closest in meaning to ________.A．preventB．imitateC．causeD．decrease59. Why does a rock avalanche move faster than other types of rockslides?A．The rock moves over a layer of compressed air.B．The rainfall is heavy where avalanches occur.C．The rock breaks apart as it moves downslope.D．The angle of the slope is almost vertical.60. The underlined word “that” in paragraph 4 refers to ________.A．resultB．consistencyC．mudflowD．mixture61. Which sentence below best expresses the essential information in the underlined sentence in paragraph 5? Incorrect choices change the meaning in important ways or leave out essential information.A．Fire has destroyed much of the original vegetation, so mudflows are now more likely.B．More damage to vegetation is caused by brush fires than by any other natural event.C．It is necessary to remove dead and damaged vegetation after a mudflow but not after a fire.D．Fires occur frequently in areas where the vegetation has been cleared for development. 62. What can be inferred from paragraph 5 about mudflows in some parts of southern California?A．Mudflows rarely occur more than once in the same location.B．Mudflows cause the worst damage in areas that are heavily forested.C．Mudflows occur more often than other natural disasters such as fires.D．Mudflows are so dangerous because people do not expect them to occur.63. Why does the author use the word “raced” in paragraph 6 while describing the lahars caused by the eruption of Mount St. Helens?A．To show that lahars are faster than rock avalanchesB．To state ironically that lahars do not actually move quicklyC．To emphasize the fast speed of laharsD．To explain why people could not outrun the mudflows64. Look at the four squares and, which indicate where the following sentence could be。

Cloze Test (10 minutes, 15 points, 1 point each)Most American magazines and newspapers reserve 60 percent of their pages for ads. The New York Times Sunday edition 36 may contain 350 pages of advertisements. Some radio stationsdevote 40 minutes of every hour to 37 .Then there is television. According to one estimate, American youngsters sit 38 three hours of television commercials each week. By the time they graduate from high school, they will have been 39 360,000 TV ads. Televisions advertise in airport, hospital waiting rooms, and schools.Major sporting 40 are now major advertising events. Racing cars serve as high-speed 41 . some athletes receive most of their money from advertisers. One 42 basketball player earned $ 3.9 million by playing ball. Advertisers paid him nine times that much to 43 their products. There is no escape. Commercial ads are displayed on walls, buses and trucks. They decorate the inside of taxis and subways ----even the doors of public toilets. 44 messages call to us in supermarkets, stores, elevators -----and 45 we are on hold on the telephone. In some countries so much advertising comes through the mail that many recipients proceed directly from the mailbox to the nearest wastebasket to 46 the junk mail. 47 Insider’s Report, published by McCann-Erickson, a global advertising agency, the estimated 48 of money spent on advertising worldwide in 1990 was $ 275.5 billion. Since then, the figures have 49 to $ 411.6 billion for 1997 and a projected $ 434.4 billion for 1998. Big money.What is the effect of all of this ? One analyst 50 it this way: “Advertising is one of the most powerful socializing forces in the culture. Ads sell more than products. They sell images, values, goals , concepts of who we are and who we should be. They shape our attitudes and our attitudes shape our behaviour.36. A lonely B alone C singly D individually37.

A raised B elevated C roared D soared50. A said B recorded C told D putPassage One For decades, arms-control talks centered on nuclear weapons. This is hardly surprising, since a single nuclear bomb can destroy an entire city. Yet, unlike smaller arms, these immensely powerful weapons have not been used in war in over 50 years.Historian John Keegan writes, “Nuclear weapons have, since August 9, 1945, killed no one. The 50,000,000 who have died in war since that date have for the most part, been killed by cheap, mass-produced weapons and small ammunitions, costing little more than the transistor radios which have flooded the world in the same period. Because small weapons have disrupted life very little in the advanced world, outside the restricted localities where drug-dealing and political terrorism flourish, the populations of the rich states have been slow to recognize the horror that this pollution has brought in its train.”Why have small arms become the weapons of choice in recent wars? Part of the reason lies in the relationship between conflict and poverty. Most of the wars fought during the 1990s took place in countries that are poor----too poor to buy sophisticated weapon systems. Small arms and light weapons are a bargain.For example, 50 million dollars, which is approximately the cost of a singlemodern jet fighter, can equip an army with 200,000 assault rifles.Another reason why small weapons are so popular is that they are lethal. A single rapid-fire assault rifle can fire hundreds of rounds a minute. They are also easy to use and maintain. A child of ten can be taught to strip and reassemble a typical assault rifle. A child can also quickly learn to aim and fire that rifle into a crowd of people.The global traffic in guns is complex. The illegal trade of small arms is big. In some African wars, paramilitary groups have bought billions o f dollars’ worth of small arms and light weapons, not with money, but with diamonds seized from diamond-mining areas.Weapons are also linked to the illegal trade in drugs. It is not unusual for criminal organizations to use the same routes to smuggle drugs in one direction and to smuggle guns in the other.51. It is implied in the passage that __________A small arms-control is more important than nuclear arms-control.B the nuclear arms-control talks can never reach an agreement.C the power of nuclear weapons to kill people has been diminished.D nuclear weapons were the topic of arms-control talks 50 years ago.52. The advanced world neglect the problems of small arms because ____A They have to deal with drug-dealing and political terrorism.B They have no such problems as are caused by small weapons.C They have not recognized the seriousness of the problems in time.D They face other more important problems such as pollution.53. Which of the following is NOT mentioned as the reason for the prevalence of small arms?A Small arms are cheap.B Small arms are powerful .C Small arms are easier to use.D Small arms are easier to get54. We can conclude from the passage that ____A small arms are not expensive in the black-market.B it is unfair to exchange small arms for diamond.C Criminals use the same passage to smuggle drugs and small arms.D where there are drugs, there are small arms.55. The best title for this passage is ____A Small Arms Talks, Not Nuclear Arms Talks.B Neglect of Small Arms ControlC Global Traffic in Small ArmsD Small Arms, Big Problems.Passage Two In order to combat sickness, many doctors rely heavily on prescribing medicines that are developed and aggressively advertised by pharmaceutical companies. Significantly, the world market for such drugs has skyrocketed in recent decades, from just a few billion dollars a year to hundreds of billions of dollars annually. What had been a consequence?Medically prescribed drugs have helped many people. Yet, the health of some who take drugs has either remained unchanged or become worse. So, recently some have turned to using other methods of medical treatment.In places where modern, conventional medicine has been the standard of care, many are now turning to what have been called alternative, or complementary, therapies. “The Berlin Wall that has long divided alternative therapies from mainstream medicine appears to be crumbling,” said Consumer Reports of May 2000.The Journal of the American Medical Association(JAMA) observed, “Alternative medical therapies such as the use of herbs, functionally defined as interventions neither taught widely in medical schools nor generally available in U. S. hospitals, have attracted increased national at tention from the media, the medical community, governmental agencies, and the public.”In the past, conventional medical practitioners have been skeptical about alternative medical practices, but 75 medical schools in the United States currently offer elective course work on alternative medicine, including Harvard, Stanford, University of Arizona, and Yale.JAMA noted, “ Now an estimated 3 in 5 individual seeing a medical doctor for a principal condition also used an alternative therapy.And outside the United States, alternative medicine is popular throughout the industrialized world.”The trend toward integrating alternative therapies with conventional ones has long been a general practice in many countries. As JAMA concluded, “There are no longer t wo types of medicine, conventional and complementary. There is only good medicine and bad medicine.”56. This passage suggests that pharmaceutical companies ____A pay doctors for prescribing their drugs.B have raised the prices of their products sharply in recent years.C spend more money on their advertisements than on their products.D have produced some ineffective drugs.57. The sentence “The Berlin Wall …. Appears to be crumbling” in the third paragraph implies that _____A the restrictions on the practice of alternative therapies will be abolished.B there are still strict restrictions on the practice of alternative drugs.C conventional medicine and alternative therapies are incomparable.D conventional medicine and alternative therapies are completely different remedies.58. According to the passage, alternative therapies _____A are widely taught in the U.S. medical schools now.B have been approved by U. S. government.C have been used by many American patients.D are as popular as conventional medicine.59. JAMA seems to suggest that ____________A U. S. government should meet the increasing demands for alternative therapies.B a medicine is good after it proves to be beneficial to the patients.C pharmaceutical companies should cover the cost of alternative therapies.D conventional medicine and alternative medicine should join hands.60. It is implied in the passage that ._____________A we should take as little western medicine as possible.B the prices of the prescribed medicine should be reduced.C herbal medicine will be accepted by more Americans.D without the help of alternative medicine, good health can not be guaranteed.Passage Three Our Milky Way galaxy could contain up to 1 billion Earth-like planets capable of supporting life, scientists announced last week.The theoretical abundance of habitable worlds among the estimated 200 billion stars of our home galaxy suggests that more powerful telescopes might glimpse the faint signature of far-off planet, proving that, in size and temperature at least, we are not alone in the universe.Solar systems such as Earth’s, in which planets orbit a star, have been discovered. Astronomers have identified almost 100 planets in orbit around other suns. All are enormous, and of the same gaseous make-up as Jupiter.Barrie Jones of the Open University in UK and his colleague Nick Sleep have worked out how to predict which of the newly discovered solar systems is likely to harbor Earth-like planets.Using a computer, they have created mathematical models of planetary systems and seeded them with hypothetical Earths in “Goldilocks zone” orbits, where it is neither too hot too cold to support life.The computer simulates which of these model Earths is likely to be kicked out of its temperature orbit by gravitational effects of the monster planets, and which is likely to survive.The solar system most like ours discovered so far is 51 light years away, at the star 47 Ursae Majoris, near the group of stars known as the Great Bear.Astronomers have discovered two planets orbiting 47 Ursae Majoris----One is two and half times the size of Jupiter, the other slightly smaller. Both planets are relatively close to the Goldilocks zone, which is further out than ours because 47 Ursae Majoris is older, hotter and brighter than the sun. “It’s certainly a system worth exploring for an Earth-like planet and for life,” said Jones. The requirement for a life-supporting zone in any solar system is that water should be able to exist in a liquid state.NASA and its European counterpart, ESA, plan to launch instruments in the next 10 years which could produce pictures of Earth-sized planets.61. It is suggested in this passage that _______________A scientists have found evidence to prove there are many Earth-like planets in our galaxy.B Theoretically there are a great number of Earth-like planets capable of supporting life.C our Earth is the only planet in our galaxy that can support life.D with more powerful telescope, scientists will be able to find more galaxies in the universe62. The “Godilocks zone” mentioned in the 5th paragraph most probably means _________A a certain fixed distance between a planet and sun.B a range in the universe in which th e planets’ temperature is suitable for life.C a range in the universe in which the planets can receive enough sunlight.D a mathematical model to measure the size of the planetary system.63. Barrie Jones and Nick Sleep have found ____________A 100 planets orbiting around other stars like our sun.B many planets’ atmosphere has the same composition as Jupiter.C the ways to tell which solar system may have Earth-like planets.D a mathematical model to measure the distance of newly found solar-systems.64. So far, the solar system most like ours that has been discovered is _______A in the group of stars known as Great Bear.B 2.5 times as big as Jupiter.C smaller than our system.D impossible for us to reach at present time.65. The most important requirement to have a life-supporting zone in any solar system is that it must have _____A enough water and proper temperature.B enough oxygen and hydrogen.C enough air and sunlight.D enough water in any state.Passage Four Having abandoned his call for higher gasoline prices, Vie President Al Gore has another idea to get people out of their cars: Spend billions on mass transit ----$ 25 billion to be exact. Last week, Gore unveiled his “Keep America Moving” initiative, which will spend $25 billion on upgrading and improving mass-transit systems nationwide. According to Gore’s self-proclaimed “new way of thinking”, all that’s necessary to reduce traffic congestion is to “give people a choice.”The federal government has been tryin g to “give people a choice” for decades to little effect. Portions of the federal gasoline tax have already been used to support urban bus and rail systems. Despite years of subsidies, few urban-transit systems run in the black. They don’t do much to reduce congestion either. No matter how much the tax-payers paid for the planned transit systems.Americans prefer the autonomy offered by their automobiles.The vice president praised the Portland light-rail system as an example of how good mass transit can be. Yet Portland’s experience is more cautionary tale than exemplary model. Research by the Cascade Policy Institute demonstrates that Portland’s Metro has been a multi-million-dollar mistake. According to Metro’s own figures, the light-rail system is doing little to reduce congestion, as most of its riders used to ride the bus. Those riders that do come off the roads, come at an incredible price: $ 62 per round trip. Road improvements and expansion would do far more to reduce congestion at a fraction of t he cost, but they wouldn’t attract the same volume of federal funds.66. According to the author, the mass-transit systems____A are characterized by low consumption of gasoline.B have contributed little to the improvement of the traffic.C aim at monitoring the public traffic.D are financially profitable.67. What does the author say about the federal government?A It has recently begun to address the problem of traffic congestion.B It fails to provide enough funds to help reduce traffic congestion.C Its attempt to reduce traffic congestion is successful but costly.D It has not done much to reduce congestion by improving roads.68. What is said about Americans’ attitude toward the transit systems?A They are reluctant to pay taxes to support the transit systems.B They think driving their own cars is more convenient.C They prefer the policies of improving and expanding roads.D They think there should be more choices in transportation.69 In the third paragraph, the underlined expression “cautionary tale” most probably means ____A an incredible storyB an untrue storyC a story giving a warningD a story teaching a moral lesson70. Which of the following statements would the author probably agree to ?A In spite of federal funds, most urban-transit systems have financial problems.B The American public should become more aware of the need to reduce traffic congestion.C The attempt to expand roads would be as costly as the one to build a light-rail system.D The federal gasoline tax should be raised to support urban-transit system.Passage Five In all of the industrial countries and many less developed countries, a debate along the lines of government vs. business prevails. This struggle has gone on for so long and is so pervasive, that many who participate in it have come to think of these two social institutions as natural and permanent enemies, each striving to oppose the other.Viewing the struggle in that format diminishes the chance of attaining more harmonious relations between government and business. Moreover, if these two are seen as natural and deadly enemies, then business has no long-range future. It is self-evident that government, as the only social instrument that can legally enforce its will by physical control, must win any struggle that is reduced to naked power.A more realistic, and most constructive, approach to the conflict between business and government starts by noticing the many ways in which they are dependent on each other. Business cannot exist without social order. Business can and does generate its own order, its own regularities of procedure and behaviour; but at bottom these rest upon more fundamental patterns of order which can be maintained and evolved by the political state.The dependence of government on business is less absolute. Governments can absorb direct responsibility for organizing economic functions. In many cases, ancient and modern, government-run economic activities seem to have operated at a level of efficiency not markedlyinferior to comparable work organized by business. If society’s sole purpose is to achieve a bare survival for its members, there can be no substantial objection to governmental absorption of economic arrangements.71. Many people think go vernment and business are “enemies” because ____A the struggle between the two parties has always existed.B they based their belief on the experience of the industrial countries.C they believe that government can do better than business in economic activities.D the struggle between the two parties is so fierce that neither will survive in the end.72. The third paragraph mainly discusses___________A how government and business depend on each other.B why social order is important to business activities.C Why it is necessary for business to rely on government.D how business can develop and maintain order.73. What does the passage say about economic activities organized by government?A They mostly aim at helping people to survive.B They can be conducted as well as those by business.C They are the ones that business can’t do well.D They are comparatively modern phenomena.74. We can conclude from the passage that ____A it is difficult for government and business to have good relations.B it is difficult to study the relations between government and business.C government should dominate economic activities.D government and business should not oppose each other .Passage Six Standing up for what you believe in can be tough. Sometimes it’s got to be done, but the price can be high.Biochemist Jeffrey Wigand found this out the hard way when he took on his former employer, tobacco giant Brown & Williamson, over its claim that cigarettes were not addictive.So too did climate modeler Ben Santer when he put his name to a UN report which argued that it is people who are warming the planet. Both men found themselves under sustained attacks, Wigand from Brown & Williamson, Santer from the combined might of the oil and car industries.The two men got into their dreadful predicaments by totally different routes. But they had one thing in common---they fought powerful vested interests （既得利益者）with scientific data that those interests wished would go away.Commercial companies are not, of course, the only vested interests in town. Governments have a habit of backing the idea of whoever pays the most tax. Academia also has its version: scientific theories often come with fragile egos and reputations still attached, and supporters of those theories can be overly resistant to new ideas.For example, Alfred Wegener’s idea that the continents drift across the surface of the planet was laughed at when he proposed it in 1915. this idea was only accepted finally in the 1960s, when plate tectonics came of age. More recently, in 1982, Stanley Prusiner was labeled crazy for his controversial suggestion that infectious diseases such as BSE（疯牛病）were caused by a protein that self-replicated. A decade later, the notion had gained ground. Finally , in 1997, he received a Nobel Prize for his idea.Western science has always thrived on individualism---- one person’s ambition to topple a theory. So independence of thought is crucial.But this applies not only for scientists, but also their institutions.With governments and commercial sponsors increasingly pulling the strings of university research---- perhaps it’s time to spend some lottery money, say, on truly independent research.Overcoming scientists’ inertia will be much more dif ficult.Yet we can’t afford to be slow to hear new ideas and adapt to them. Back in the 1950s, if governments had taken seriously the findings of epidemiologist Richard Doll about the link between smoking and lung cancer, millions of people would have been spared disability and premature death.75. One of the ideas that are highlighted in the passage is that __________A individuals have greater chance of success in scientific research than collectives.B personality plays a crucial role in the advance of science.C originality of thinking is the key to the advance of science.D the intelligence of scientists is of vital importance to scientific achievements.76. Jeffrey Wigand’s idea about the nature of cigarette__________A was similar to that of the tobacco company.B sounded ridiculous to the general public .C was reached purely out of personal interestsD should be regarded as scientifically true.77. Jeffrey Wigand was attacked by the tobacco giant because _____A his idea could lead to a financial loss for the company.B he had been eager to defeat his company.C his idea was scientifically invalid.D he had long been an enemy of the company.78. The underlined phrase “place tectonics” in the 5th paragraph probably refers to ____A the study of the structure of the earthB scientific study of the climate of the earth.C the theory that the earth’s surface consists of plates in constant motion.D the theory that the earth’s surface was originally a plate-shaped heavenly body.79. One of the conclusions that we can reach from this passage is that ____A governmental interests always seem to clash with those of the private companies.B scientific findings are often obtained at the sacrifice of personal interests.C scientific truths are often rejected before they are widely accepted.D scientists are sometimes doubtful about their beliefs.80. The author seems to be suggesting that _______A the vested interests are sometimes on obstacle to the progress of science.B governments are the one to blame for the deterioration of the environment.C a timely response to people’s demand is appreciated by the academia.D the interference by the government resulted in the tragedy of the 1950s.Part V Translation (40 minutes, 20 points )The nations meeting here in Shanghai understand what is at stake. If we don’t stand against terrorism now, every civilized nation will at some point be its target. We will defeat the terrorists by destroying their network, wherever it is found. We will also defeat the terrorists by building an enduring prosperity that promises more opportunity and better lives for all the world’s people.The countries of the Pacific Rim made the decision to open themselves up to the world, and the result is one of the great development success stories of our time. The peoples of this region are more prosperous, healthier, and better educated than they were only two decades ago. And this progress has proved what openness can accomplish.Section B ( 20 minutes, 10 points )也许你觉得自己那些静卧于抽屉中的家书措辞不够优美，气息也不够现代，其实这正是我们所需要的，/毕竟时代的烙印和真挚的情怀是挥之不去，那亘古不变的魔力足以超出我们的想象。
