二、阅读理解(每题 10 分，共 5 题)Passage 1

Everyone has heard of the San Andreas fault (断层), which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri? Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur （硫磺）to filter upward. The Mississippi River itself completely changed character, developing sudden rapids and whirlpools. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C. Scientists now know that America’s two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the movement of these two masses suddenly lurches (倾斜) forward. The New Madrid fault, on the other hand, is a vertical fault; a some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions trigger (触发) earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern lllinois.

第 2 页

Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but the scientists say have no method of predicting when a large earthquake will occur.31. This passage is mainly about　　　　 . A the New Madrid fault in Missouri B the San Andreas and the New Madrid faults C the causes of faults D current scientific knowledge about faults32. The New Madrid fault is　　　　　. A a horizontal fault B a vertical fault C a more serious fault than the San Andreas fault D responsible for forming the Mississippi River33. We may conclude from the passage that　　　　　 . A it is probably as dangerous to live in Missouri as in California B the New Madrid fault will eventually develop a mountain range in Missouri C California will become an island in future D A big earthquake will occur to California soon34. This passage implies that　　　　　　. A horizontal faults are more dangerous than vertical faults. B Vertical faults are more dangerous than horizontal faults C Earthquakes occur only around fault areas D California will break into pieces by an eventual earthquake35. As used in the first sentence of the fourth paragraph, the word “essentially” means　　　　. A greatly　　B extremely C basically　D necessarily

Passage 2

The law is a great mass of rules, showing when and how far a man is possible to be punished, or to be made to hand over money or property to his neighbors, and so on. These rules are contained in books. A lawyer learns them mainly by reading books. 　　He begins by doing little else than read, and after he has prepared himself by. say. three years’study practice, still, all his life long and almost every day, he will be looking into books to read a little more than he already knows about some new questions which he has to answer. 　　The power to use books, then. is a special skill which the would - be lawyer ought to possess. He ought to have enough flexibility（灵活性）to make it easy for him to collect ideas from printed words. He ought to have some readiness in finding what a book contains, and something of an instinct （直觉）for where to look for what he wants.　　But although this is the power of which he will first feel the need, it is not the most important. A lawyer does not study law to recite it; he studies it to use it and act upon the rules which he has learned in real life. His business is to try eases in court and to advise men what to do in order to keep out or get out of trouble. 36．The first thing a law student has to do is to________.　　A. read books 　　B. hand over money　　C. practice law 　　D. answer questions37．After three years of reading________.　　A. he can study law 　　B. he can stop reading　　C. he still has to continue reading　　D. he is able to give clever answers38．The major business of a lawyer is________.　　A. to discuss the material he has read　　B. to advise people who have law problems　　C. to learn about real life 　　 D. to study the law39．According to the passage, a good lawyer should know how to________.

To possess a lot of books.　　B. to have enough flexibility when collecting ideas from printed words.　　C. To be ready to find out what a book contains.　　D. To be able to use his book knowledge in the right way in his future business.

Passage 3

A lot of recent papers point out how talking with your hands can unlock what Krauss calls "lexical (词汇的) memory". One study, for instance, finds that speakers gesture more when they try to define words that have a strong spatial (空间的) component -- like "under" or "neighboring'' -- than when defining words that are more abstract, like "thought" or "evil". And doctors notice that stroke patients whose brain damage worsens their ability to name objects gesture more, "as if they are trying everything they can to come up with a word," says Krauss. Even people who don't think they're gesturing may be. Krauss attached electrodes to people's arms to measure the movements of their muscles -- a little clench (握拳) that doesn't blossom into a full gesture. Then he asked them to come up with words that fit a definition he supplied. "You get more muscle movement when they say a word like 'castanets(响板，一种乐器) ' which has an implied meaning of movement, than when they say an abstract word like 'mercy'", he finds. If gesturing is like using a key to the door of lexical memory, then someone who can' t use his hands should have more trouble unlocking the door. That is just what a new study in the American Journal of Psychology finds. In the experiment, volunteers held onto a bar to keep their hands still; when Donna Frick-Horbury of Appalachian State University in North Carolina read them definitions "an ancient instrument used for calculations in eastern countries", the subjects more often failed to think of the word "abacus" or took longer to do it, than when they could gesture freely. "Many subjects would actually make motions of using an abacus before coming up with the word," says psychologist Robert Guttentag of the University of North Carolina at Greensboro, who was observing the study.41. Gestures can help speakers to recall __ in their memory. A) words B) definitions C) meanings D) ideas42. When do speakers use gestures more often? A) When they are excited.

B) When they talk about something emotional. C) When they say some spatial words.D) When they say some abstract words.

43. Kranss attached electrodes to people's arms in order to __A) observe the moments of their muscles B) measure the damage degree of the brain C) supply the meaning to a gesture

D) define the meaning of a word44.What is the meaning of the word "blossom" in Para. i? A) Bloom. B) Flower. C) Operate. D) Develop.45. According to the passage, who can get more words from the "lexieal memory"? A) People who eau memorize words very fast. B) People who gesture more often. C) People who hold onto a bar. D) People who seldom gesture.

Passage 4

第 4 页

Taste is such a subjective matter that we don 't usually conduct preference tests for food. The most you can say about anyone 's preference, is that it's one person's opinion. But because the two big cola (可乐饮料)companies----Coca-Cola and Pepsi Cola are marketed aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either C0ca-Cola or Pepsi fans: Find your brand in a blind tasting. We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型)or Pepsi, Diet (低糖的)Coke, or Diet Pepsi-These were people who thought they'd have no trouble telling their brand from the other brand. We eventually located 19 regular cola drinkers and 27 diet cola drinkers. We eventually located 19regular cola drinkers and 27diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants 'choices with what mere gum-work would have accomplished. Getting all four samples right was a tough test, but not too tough, we thought , for people who believed they could recognize their brand. In the end, only 7out of 19regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse -only 7of27identified all four samples correctly . While both groups did better than chance would predict ,nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall ,half the participants did about as well on the last round of tasting as on the first ,so fatigue, or taste burn out, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

46.According to the passage the preference test was conducted in order to A) find out the role taste preference plays in a person's drinking B)reveal which cola is more to the liking of the drinkers C)show that a person's opinion about taste is mere guess-work D)compare the ability of the participants in choosing their drinks

47.The statistics recorded in the preference tests show A)Coca-Cola and Pepsi are people's two most favorite drinks B) there is not much difference in taste between Coca-Cola and Pepsi C) few people had trouble telling Coca-Cola from Pepsi D)people's tastes differ from one another

48.It is implied in the first paragraph that A)the purpose of taste tests b to promote the sale of colas B)the improvement of quality is the chief concern of the two cola companies C)the competition between the two colas is very strong D)blind tasting is necessary for identifying fans

49.The word "burnout"(Line4,Para.5)here refers to the state of A)being seriously burnt in the skin B)being unable to burn for lack of fuel C)being badly damaged by fire D)being unable to function because of excessive use

50.The author's purpose in writing this passage is to A)show that taste preference is highly subjective B)argue that taste testing is an important marketing strategy C)emphasize that taste and price are closely related to each other

第 5 页

D)recommend that blind tasting be introduced in the quality control of colas

Passage 5

Good sense is the most equitably distributed thing in the world, for each man considers himself so well provided with it that even those who are most difficult to satisfy in everything else, do not usually wish to have more of it than they have already. It is not likely that everyone is mistaken in this; it shows, rather, that the ability to judge rightly and separate the true from the false, which is essentially what is called good sense or reason, is by nature equal in all men, and thus that our opinions differ not because some men are better provided with reason than others, but only because we direct our thoughts along different paths, and do not consider the same things. For it is not enough to have a good mind; what is most important is to apply it rightly. The greatest souls are capable of the greatest evils, and those who walk very slowly can advance much further, if they always keep to the direct road, than those who run and go astray. And I know of no other qualities than these which make for the perfection of the mind; for as to reason, or good sense, because it alone makes us men and distinguishes us from the beasts, I am quite willing to believe that it is whole and entire in each of us.51. According to the author, the ability to distinguish between the true and the false is _______. A) given by nature to all creatures B) given in equal measure to all persons C) more heavily present to some persons than in others D) an unnatural, cultivated characteristic in all persons52. The author claims that what sets human beings apart from beasts is ______. A) a sense of organization combined with the ability to create B) the ability to adapt to the surroundings C) a sense of reason coupled with a strong sense of practicability D) a sense of reason53. The basic idea of the passage may be stated as follows: A) All persons have an equal portion of good will when they are born. B) Great souls are capable of great evils. C) Good sense, in terms of its distribution among persons, may be called common sense. D) Good sense is the mark of the truly good person.54. According to the author, a good sense is _______. A) the ability to distribute things equally B) the ability to judge correctly and to distinguish the true from the false C) the ability to direct our thoughts along different paths D) the ability to always keep to the direct road55. By "Good Sense" the author means _______. A) the power to deduce B) the power to make a good judgement C) a good feeling for actors D) the power to understand

二、阅读理解(每题 10 分，共 5 题)Passage 1

American are proud of their variety an individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five star - general. Why are uniforms so popular in the United States?　　Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian （百姓的）clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears a uniform tends to inspire more trust than one who appears in civilian clothes, Faith in the skill of a garage mechanic is increased by a uniform . What easier way is there for a nurse, a policeman, a barber, or a waiter to lost professional identity（身份）than to step out of uniform?　　Uniforms also have many practical benefits. They save on other clothes, They save on laundry bills. They are tax - deductible （可减税的）. They are often more comfortable and more durable than civilian clothes.　　Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least.　　Uniforms also give rise to some practical problems. Though they are long - lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.31．It is surprising that Americans who worship variety and individuality________.　　A. still judge a man by his clothes　　B. hold the uniform in such high regard

Uniform and Society　　B. The Importance of Wearing a Uniform．　　C. Practical Benefits of Wearing a Uniform.

Passage 3

One of the most daring deep-space missions NASA has ever launched is turning out to be one of the least publicized. The target is a large asteroid (小行星) named 1992KD, which orbits the sun millions of miles from Earth. But that destination is almost incidental to the performance of the spacecraft that will make the trip. Though it looks little different from countless other unmanned probes NASA has launched, the ship will be navigated by an electronic brain that has been likened to HAL, the independent-minded computer in the film 2001, and will move through space under power of a system that has long been the stuff of technological fantasies: an ion propulsion (离子推进) engine. If all goes as planned, Deep Space 1, scheduled for launch later this month, will be the forerunner of a new' generation of spacecraft. While flight planners hope the ship will make some interesting observations about the target asteroid, including its composition and the structure of its surface, DS1 's primary assignment is to validate a host of new technologies NASA has always consideral too risky to try on a mission that may attract a great deal of public attention. Says Mar Rayman of Jet Propulsion Laboratory, DS1' s chief engineer, "We have an unproven propulsion system, powered by an unproven solar panel, commanded by an unproven navigation system. What is most remarkable about the spacecraft is how it gets from place to place. After being launched by an ordinary rocket, DS1 will be pushed through space by an engine that works by firing electrons into atoms of xenon gas, stripping each of an electron and giving the atoms an electric charge -- ion/zing them. The ions are then accelerated through an electric field and emitted from the thrusters at 65,000 m. p. h. Despite that speed, the particles produce little thrust, comparable to the weight of a piece of paper.41. What is special about NASA's planned deep-space mission regarding its publicity? A) It is targeted at a large asteroid. B) it is much less reported by the media. C) It is the same as other unmanned probes. D) It isn't certain whether it will be successful.42. What is the primary, purpose of the DS1 mission? A) Testing new technologies for future spacecraft. B) Calculating risks for the benefit of other missions. C) Studying the surface of a large asteroid. D) Proving a new' generation of spacecraft.43.

Passage 4

Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart for a metal-and-plastic pump-convinced the press, the public and many doctors that the future had arrived. It hadn't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning (禁止) the device. The recall may hurt Symbion Inc, maker of the Jarvik-7, but it wont end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection (感染). Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient 's chest. The first samply products aren't expected for another 10 or 20 years. But some people are already worrying that they'll work-and that America`s overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures (开支) cut into funding for more basic care, the net effect could actually be a decline in the nation's health.

46. According to the passage the Jarvik-7artificial heart proved to be_______. A)a technical failure B)a technical wonder C)a good life-saver D)an effective means to treat heart disease

47. From the passage we know that Symbion Inc ______. A)has been banned by the government from producing artificial hearts B)will review the effects of artificial hearts before designing new models C)may continue to work on new models of reliable artificial hearts D)can make new models of artificial hearts available on the market in 10 to 20 years

48. The new models of artificial hearts are expected ______. A)to have a working life of 10 or 20 years B)to be set fully in the patient's chest C)to be equipped with an external power source D)to create a new passage for infection 49. The word "them" in Line 7, Para. 2 refers to _____ A) doctors who treat heart diseases B) makers of artificial hearts C) America's health-care programs D) New model of artificial hearts

50. Some people feel that______. A)artificial hearts are seldom effective B)the country should not spend so much money on artificial hearts

C)the country is not spending enough money on artificial hearts D)America's health-care programs are not doing enough for the nation's health

Passage 5

Time spent in a bookshop can be most enjoyable, whether you are a book-lover or merely there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings. The desire to pick up a book with an attractive dust-jacket is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book. You soon become engrossed in some book or other, and usually it is only much later that you realize you have spent far too much time there and must hasten to keep some forgotten appointment--without buying a book, of course. This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart's content. If it is a good shop, no assistant will approach you with the inevitable greeting: "Can I help you, sir?" You needn't buy anything you don't want. In a bookshop, an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course, you may want to find out where a particular section is, but when he has led you there, the assistant should leave politely and look as if he is not interested in selling a single book. You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing--something which had only vaguely interested you up until then. This volume on the subject, however,happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section. Book sellers must be both long-suffering and indulgent.

51. In a good bookshop, _______. A) nobody takes any notice of you B) the assistant greets you in a friendly way C) you feel that you are in a music shop D) your heart is contented52. An assistant should help you ________. A) as soon as you have entered the shop B) just before you finish browsing C) only when you have finished browsing D) when he leads you to a particular section53. It is very easy to enter a bookshop and buy _______. A) a book on ancient coins B) a best-selling novel on brass-rubbing C) a book that vaguely interests you D) a book that unexpectedly interests you54. According to the author, the best way to escape the realities of routine life is _______. A) to chat with a friendly assistant in a bookshop B) to wander in the streets C) to buy a best-selling novel to read D) to stay reading books of various kinds in a bookshop55. The best title for this passage may be _______.

二、阅读理解(A、B、C、D、E 每题 10 分，共 5 题)

A. If suitable competitive advantage depends on workforce skills, American firms have a problem. Human-resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered an individual responsibility.

The lack of importance attached to human-resource management can be seen in the corporate hierarchy(社团中的等级制度). In an American firm the chief financial officer is almost always second in command. The post of head of human-source management is usually a specialized job, off at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer.

While American firms often talk about the vast amounts spent on training their work forces, in fact they invest less in the skills of their employees than do either Japanese or German firms. The money they do invest is also more highly concentrated on professional and managerial employees. And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies.

As a result, problems emerge when now breakthrough technologies arrive. If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers in Germany (as they do), the effective cost of those stations is lower in Germany than it is in the United States.

31. Which of the following applies to the management of human resources in American companies? A) They hire people at the lowest cost regardless of their skills. B) They see the gaining of skills as their employees’ own business. C) They attach more importance to workers than to equipment. D) They only hired skilled workers because of keen competition.32. What is the position of the head of human resource in an American firm? A) He is one of the most important executives in the firm. B) His post is likely to disappear when new technologies are introduced. C) He is directly under the chief financial executive. D) He has no say in making important decisions in the firm.

第 16 页

33. The money most American firms put in training mainly goes to ______. A) workers who can operate new equipment B) professional and managerial staff C) workers who lack basic ground skills D) top executives34. What’s the main idea of the passage? A) American firms are different from Japanese and German firms in human resource management. B) Extensive retraining is indispensable to effective human-resource management. C) The head of human resource management must be in the central position in a firm’s hierarchy. D) The human resource management strategies of American firms will affect their competitive capacity.35. According to the passage, the decisive factor in maintaining a firm’s competitive advantage is ____________. A) the introduction of new technologies B) the improvement of workers’ basic skills C) the rational composition of professional and managerial employees D) the attachment of importance to the bottom half of the employees

B. Oceanography has been defined as 'The application of all sciences to the study of the sea'. Before the nineteenth century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in-his writings, but he was reluctant (不愿意) to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, 1et alone to ask what lay beneath the surface. The first time that the question ‘What is at the bottom of the oceans?' had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile (起伏形状)of the mute to estimate the length of cable that had to be manufactured. It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s,Maury had been responsible for encouraging voyages during which soundings(测深) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872Thomson led a scientific expedition (考察), which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.

36. The passage implies that the telegraph cable was built mainly_____ A)for oceanographic studies C)for business considerations B)for military purposes D)for investigating the depths of the oceans

37.It was_____ that asked Maury for help in oceanographic studies. A)the American Navy B)some early intercontinental travellers C)those who earned a living from the sea D)the company which proposed to lay an undersea cable

A)to make some sound experiments in the oceans B)to collect samples of sea plants and animals C)to estimate the length of cable that was to be made D)to measure the depths of two oceans

39.‘Defied' in the 5th paragraph probably means_____ A)‘doubted' B)‘gave proof to' C)‘challenged' D)‘agreed to'

40.This passage is mainly about________ A)the beginnings of oceanography B)the laying of the first undersea cable C)the investigation of ocean depths D)the early intercontinental communications

C. Less than a month from graduation day, Theresa Casebeer of Northwestern University in Evanston, Illinois, had yet to find the right job. The career placement center referred the liberalarts (文科) major to JOB-TRAK, an Internet site listing 45,000 positions. Casebeer selected four keywords: Chicago, business, marketing and full-time. Immediatelyshe found 45 jobs meeting her criteria (标准), including one as an assistant to an administrator at the University of Chicago's business school. Four weeks later she was hired at a starting salary of $ 32,000. "I had no training," says Casebeer, "but the Internet was extremely easy to use. I' d never have known about this job without it." Casebeer is one American who clicked (发出卡擦声) her way into a job. Steven Toole is another. In 1996, Toole came across an employment site named Career-Builder. He had just been pro-rooted to director of marketing for a company mad wash' t looking for a job. But curious, he decided to "give it a try". Toole filled out a profile (个人简历) with the keywords marketing manager and entered his electronic-mail address. Within a week his computer' s mailbox was filling up with available positions. Two interviews later he jumped to a new job. "The Internet is like hiring a personal assistant," says Toole. "Effortlessly you can become aware of opportunities that may elevate your career.” Most major newspapers and trade publications have on-line versions of their classified listings, enabling job-seekers to scan for work available across town, in another state or around the world. All 50 states, plus Washington, D. C., and Guam, have their local job banks available on-line, too. "The Internet is a wonderful place to explore, especially when coupled with traditional job search methods," notes Richard Nelson, author of What Color Is Your Parachute?

D. Researchers have established that when people are mentally engaged , biochemical changes occur in the brain that allow it to act more effectively in cognitive (认知的)areas such as attention and memory. This is true regardless of age. People will be alert (警觉的)and receptive (愿意接受的)if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind. Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize enormous amounts of information," says James Fozard, associate director of the National Institute on Aging. "Most of us don't need that kind of skii1.Such specific training is of less interest than being able to maintain mental alertness. "Fozard and others say they challenge their brains with different mental skills, both because t hey enjoy them and because they are sure that their range of activities will help the way their brains work. Gene Cohen ,acting director of the same institute ,suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says. "Intellectual activity actually influences brain-cell health and size."

46.People who are cognitively healthy are those A) whose minds are alert and receptive B) who are highly intelligent. C)who can remember large amounts of informationD)who are good at recognizing different sounds

47.According to Fozard's argument, people can make their brains work more efficiently by A)constantly doing memory work B)making frequent adjustments C)going through specific training D)taking part in various mental activities

48.The findings of James and other scientists in their work A)remain a theory to be further proved B)have been challenged by many other experts C)are practised by the researchers themselves D)have been generally accepted

49.Older people are generally advised to A) keep mentally active by challenging their brains B)keep fit by going in for physical activities C)maintain mental alertness through specific training D)maintain a balance between individual and group activities

第 19 页

50.What is the passage mainly about? A)How biochemical changes occur in the human brain. B)Why people should receive special mental training as they age. C)How intellectual activities influence brain-cell health. D)Why people should keep active not only physically but a1so mentally.

E. In early days no medical college took a woman student. Elizabeth Blackwell, however, was determined to become a doctor. The young American wrote again and again to a number of medical colleges, asking if she could be enrolled but each time the answer was NO. Then one day, to her surprise, she got a letter from the dean of a college in Geneva, which said YES. At first Geneva College, like the other colleges, was not willing to enroll Liza. But later the important people of that college learned that Liza's application had the support of a famous doctor, and they were afraid to offend that man. So the dean decided to play a trick by turning the matter over to the student's general meeting of the college, thinking that the students would be the last to agree to take Liza. When the boy students met, most students took no interest in the matter. Of the rest, some considered the young American's idea interesting and some thought by having Liza they would be proud of their college training the world's first woman doctor. Very soon the students all agreed to accept Elizabeth. The dean of Geneva College was of course very sorry to learn this, but seeing that he could do nothing to keep Elizabeth out, he gave in.

51. Elizabeth was surprised by the dean's letter, because it promised her to ______. A) have free medical education B) go to Geneva C) become a student in his college D) go to Italy52.

Some students thought if they let Elizabeth join them they could make ______. A) her proud B) the dean proud C) Geneva College proud D) him proud55. The dean was very sorry when he saw his trick ________. A) worked B) failed C) succeeded D) failure

A. It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problems, and that they have no sense of humor, at least in parent-child relationships.

I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.

Young people often irritate their parents with their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers of vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are leaders in style and taste.

Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog; you cannot win; but at least you keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself.

If you plan to control your life, cooperation can be part of that plan. You can charm others, especially your parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.31.The author is primarily addressing __________ .

A) parents of teenagersB) newspaper readersC) those who give advice to teenagersD) teenagers

32.The first paragraph is mainly about __________ .A)the teenagers’ criticism of their parents

B)misunderstandings between teenagers and their parentsC)the dominance of the parents over their childrenD)the teenagers’ ability to deal with crises

33.Teenagers tend to have strange clothes and hairstyles mainly because they _______.A) want to show their existence by creating a culture of their ownB) have a strong desire to be leaders in style and tasteC) have no other way to enjoy themselves betterD) want to irritate their parents

34.Teenagers do not want their parents to approve of whatever they do because they _________.A)have already been accepted into the adult worldB)feel that they are superior in a small way to the adultsC)are not likely to win over the adults

D)have a desire to be independent35.To improve parent-child relationships, teenagers are advised to be _______.

A) obedient B) responsible C) cooperative D) independent

B. Space is a dangerous place, not only because of meteors(流星) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere, they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damage, and this will not be discovered until the birth of deformed children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation, and during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.36. According to the first paragraph, the atmosphere is essential to man in that ________________. A) it protects him against the harmful rays from space B) it provides sufficient light for plant growth C) it supplies the heat necessary for human survival D) it screens off the falling meteors37. We know from the passage that _________________. A) exposure to even tiny amounts of radiation is fatal B) the effect of exposure to radiation is slow in coming C) radiation is avoidable in space exploration D) astronauts in spacesuits needn’t worry about radiation damage38. The harm radiation has done to the Apollo crew members ______________. A) is insignificant B) seems overestimated C) is enormous D) remains unknown39. It can be inferred from the passage that _________________. A) the Apollo mission was very successful B) protection from space radiation is no easy job C) astronauts will have deformed children or grandchildren D) radiation is not a threat to well-protected space explorers40. The best title for this passage would be ___________________. A) The Atmosphere and Our Environment B) Research on Radiation C) Effects of Space Radiation D) Importance of Protection against Radiation

C. A lot of recent papers point out how talking with your hands can unlock what Krauss calls "lexical (词汇的) memory". One study, for instance, finds that speakers gesture more when they try to define words that have a strong spatial (空间的) component -- like "under" or "neighboring'' -- than when defining words that are more abstract, like

第 24 页

"thought" or "evil". And doctors notice that stroke patients whose brain damage worsens their ability to name objects gesture more, "as if they are trying everything they can to come up with a word," says Krauss. Even people who don't think they're gesturing may be. Krauss attached electrodes to people's arms to measure the movements of their muscles -- a little clench (握拳) that doesn't blossom into a full gesture. Then he asked them to come up with words that fit a definition he supplied. "You get more muscle movement when they say a word like 'castanets(响板，一种乐器) ' which has an implied meaning of movement, than when they say an abstract word like 'mercy'", he finds. If gesturing is like using a key to the door of lexical memory, then someone who can' t use his hands should have more trouble unlocking the door. That is just what a new study in the American Journal of Psychology finds. In the experiment, volunteers held onto a bar to keep their hands still; when Donna Frick-Horbury of Appalachian State University in North Carolina read them definitions "an ancient instrument used for calculations in eastern countries", the subjects more often failed to think of the word "abacus" or took longer to do it, than when they could gesture freely. "Many subjects would actually make motions of using an abacus before coming up with the word," says psychologist Robert Guttentag of the University of North Carolina at Greensboro, who was observing the study.

41. Gestures can help speakers to recall __ in their memory. A) words B) definitions C) meanings D) ideas42. When do speakers use gestures more often? A) When they are excited.

B) When they talk about something emotional. C) When they say some spatial words.D) When they say some abstract words.

43. Kranss attached electrodes to people's arms in order to __A) observe the moments of their muscles B) measure the damage degree of the brain C) supply the meaning to a gesture

D) define the meaning of a word44.What is the meaning of the word "blossom" in Para. i? A) Bloom. B) Flower. C) Operate. D) Develop.45. According to the passage, who can get more words from the "lexieal memory"? A) People who eau memorize words very fast. B) People who gesture more often. C) People who hold onto a bar. D) People who seldom gesture.

D. Taste is such a subjective matter that we don 't usually conduct preference tests for food. The most you can say about anyone 's preference, is that it's one person's opinion. But because the two big cola (可乐饮料)companies----Coca-Cola and Pepsi Cola are marketed aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either C0ca-Cola or Pepsi fans: Find your brand in a blind tasting. We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型)or Pepsi, Diet (低糖的)Coke, or Diet Pepsi-These were people who thought they'd have no trouble telling their brand from the other brand. We eventually located 19 regular cola drinkers and 27 diet cola drinkers. We eventually located 19regular cola drinkers and 27diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants 'choices with what mere gum-work would have accomplished. Getting all four samples right was a tough test, but not too tough, we thought , for people who believed they could recognize their brand. In the end, only 7out of 19regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse -only 7of27identified all four

第 25 页

samples correctly . While both groups did better than chance would predict ,nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall ,half the participants did about as well on the last round of tasting as on the first ,so fatigue, or taste burn out, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

46.According to the passage the preference test was conducted in order to A) find out the role taste preference plays in a person's drinking B)reveal which cola is more to the liking of the drinkers C)show that a person's opinion about taste is mere guess-work D)compare the ability of the participants in choosing their drinks

47.The statistics recorded in the preference tests show A)Coca-Cola and Pepsi are people's two most favorite drinks B) there is not much difference in taste between Coca-Cola and Pepsi C) few people had trouble telling Coca-Cola from Pepsi D)people's tastes differ from one another

48.It is implied in the first paragraph that A)the purpose of taste tests b to promote the sale of colas B)the improvement of quality is the chief concern of the two cola companies C)the competition between the two colas is very strong D)blind tasting is necessary for identifying fans

49.The word "burnout"(Line4,Para.5)here refers to the state of A)being seriously burnt in the skin B)being unable to burn for lack of fuel C)being badly damaged by fire D)being unable to function because of excessive use

50.The author's purpose in writing this passage is to A)show that taste preference is highly subjective B)argue that taste testing is an important marketing strategy C)emphasize that taste and price are closely related to each other D)recommend that blind tasting be introduced in the quality control of colas

E. Time spent in a bookshop can be most enjoyable, whether you are a book-lover or merely there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings. The desire to pick up a book with an attractive dust-jacket is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book. You soon become engrossed in some book or other, and usually it is only much later that you realize you have spent far too much time there and must hasten to keep some forgotten appointment--without buying a book, of course. This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart's content. If it is a good shop, no assistant will approach you with the inevitable greeting: "Can I help you, sir?" You needn't buy anything you don't want. In a bookshop, an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course, you may want to find out

第 26 页

where a particular section is, but when he has led you there, the assistant should leave politely and look as if he is not interested in selling a single book. You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing--something which had only vaguely interested you up until then. This volume on the subject, however,happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section. Book sellers must be both long-suffering and indulgent.

51. In a good bookshop, _______. A) nobody takes any notice of you B) the assistant greets you in a friendly way C) you feel that you are in a music shop D) your heart is contented52. An assistant should help you ________. A) as soon as you have entered the shop B) just before you finish browsing C) only when you have finished browsing D) when he leads you to a particular section53. It is very easy to enter a bookshop and buy _______. A) a book on ancient coins B) a best-selling novel on brass-rubbing C) a book that vaguely interests you D) a book that unexpectedly interests you54. According to the author, the best way to escape the realities of routine life is _______. A) to chat with a friendly assistant in a bookshop B) to wander in the streets C) to buy a best-selling novel to read D) to stay reading books of various kinds in a bookshop55. The best title for this passage may be _______. A) Don't Waste Your Time in a Bookshop B) Bookshop and Its Assistants C) On Buying Books D) Keep Your Appointment三、完形填空(每题 20 分，共 1 题)

二、阅读理解(共 5 个阅读，每个 10 分，31-55 题)

The “balance of nature” is not an empty phrase. Nature provides a population to occupy a suitable environment and cuts down surplus population to fit the available food supply. One means of reducing surplus population is predators(食肉动物); others are parasites(寄生虫) and diseases. Also, population density produces nervous disorders and even drivers animals to mass migrations, like the lemmings(旅鼠) of Norway who plunge(跳入) into the sea.

That predators populations increase to control other animals has long been known. Many years ago, the Hudsons Bay Company records revealed that the fox population went up and down about a year after the rabbit population had gone up and down.

Sometimes a situation occurs in which the predator population is reduced to a level below that which nature can readily replace. On Valcour Island in Lake Champlain (New York), a costly campaign resulted in the elimination of predatory animals only to have birds and small animals (including grouse(松鸡) and hares, popular game) increase for four years afterward. Then, lacking predator control, nature resorted to disease to cut down these populations.

Jamaica had an example of natures persistence in providing animals for existing habits. Sugar planters, about 75 years ago, imported mongooses(猫鼬) to control rats. The mongooses killed off the rats and, with plentiful food, multiplied. Rats became scarce and the mongooses ate lambs, kids, puppies(小狗)，and wildlife. Eventually, food became scarce and the mongooses’ population declined.31.The phrase “balance of nature” (Line 1, Para. 1) means ____________.

A) reducing the population of predatorsB) keeping the right number of animals for the right amount of foodC) keeping the ration of small game to predatorsD) driving animals t mass migrations

32.The fact that number of predators has much to do with that of other animals ______.A) is not recent knowledge B) has just been learnedC) has not proved yet D) is not important now

33. When predators control fails, nature brings animal population into balance by _______.A) eliminating the number of predatorsB) increasing the number of other animalsC) seeping the help of disease to reduce other animalsD) replacing the number of predators immediately

34. When the mongooses in Jamaica killed off the rats they ___________.第 30 页

A) attacked humans B) ate the sugar crop C) became problems themselves D) had nothing to eat35. It is implied in the passage that ___________. A) sugar planter imported mongooses to control rats B) man should never kill animals C) man has complete control over nature D) to upset the balance of nature can be troublesome

Is it possible to persuade mankind to live without war? War is an ancient institution which has existed for at least six thousand years. It was always wicked and usually foolish, but in the past the human race managed to live with it. Modern ingenuity has change this. Euther Man will abolish war, or war will abolish Man. For the present, it is nuclear weapons that cause the gravest danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in massacre, but by arbitration in accordance with agreed principles of law. It is not easy to change age-old mental habits, but this is what must be attempted.

There are those who say that the adoption of this or that ideology would prevent war. I believe this to be a profound error. All ideologies are based upon dogmatic assertions which are, at best, doubtful, and at worst, totally false. Their adherents believe in them so fanatically that they are willing to go to war in support of them.

The movement of world opinion during the past two years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the international sphere, but the spirit in which they are being approached is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between East and West, but between Man and the H-bomb.36. This passage implies that war is now _____________. A) more wicked than in the past B) as wicked as in the past C) less wicked than in the past D) what people try to live with37. According to the author ________________. A) it is impossible to live without war B) war is the only way to settle international disagreements C) war must be abolished if Man wants to survive D) war will be abolished by modern ingenuity38. The author says that modern weapons _____________. A) abolish nuclear weapons B) put mankind in grave danger C) will gradually become part of Man’s life D) need further improving39. The author believes that the only way to abolish war is to _______________. A) adopt to that ideology B) abolish nuclear and chemical weapons

A) nuclear war will definitely not take place B) international agreements are now reached more and more easily C) Man is beginning to realize that nuclear war is his greatest enemy D) world opinion is in favor of nuclear war

One of the most daring deep-space missions NASA has ever launched is turning out to be one of the least publicized. The target is a large asteroid (小行星) named 1992KD, which orbits the sun millions of miles from Earth. But that destination is almost incidental to the performance of the spacecraft that will make the trip. Though it looks little different from countless other unmanned probes NASA has launched, the ship will be navigated by an electronic brain that has been likened to HAL, the independent-minded computer in the film 2001, and will move through space under power of a system that has long been the stuff of technological fantasies: an ion propulsion (离子推进) engine. If all goes as planned, Deep Space 1, scheduled for launch later this month, will be the forerunner of a new' generation of spacecraft. While flight planners hope the ship will make some interesting observations about the target asteroid, including its composition and the structure of its surface, DS1 's primary assignment is to validate a host of new technologies NASA has always consideral too risky to try on a mission that may attract a great deal of public attention. Says Mar Rayman of Jet Propulsion Laboratory, DS1' s chief engineer, "We have an unproven propulsion system, powered by an unproven solar panel, commanded by an unproven navigation system. What is most remarkable about the spacecraft is how it gets from place to place. After being launched by an ordinary rocket, DS1 will be pushed through space by an engine that works by firing electrons into atoms of xenon gas, stripping each of an electron and giving the atoms an electric charge -- ion/zing them. The ions are then accelerated through an electric field and emitted from the thrusters at 65,000 m. p. h. Despite that speed, the particles produce little thrust, comparable to the weight of a piece of paper.41. What is special about NASA's planned deep-space mission regarding its publicity? A) It is targeted at a large asteroid. B) it is much less reported by the media. C) It is the same as other unmanned probes. D) It isn't certain whether it will be successful.42. What is the primary, purpose of the DS1 mission? A) Testing new technologies for future spacecraft. B) Calculating risks for the benefit of other missions. C) Studying the surface of a large asteroid. D) Proving a new' generation of spacecraft.43. Once launched, whether the spacecraft will reach its destination is incidental to the performance of all the following EXCEPT __ A) the self-navigation system C) the solar cells B) the ion-powered engine D) the flight planners44. How does the DS1 leave the earth's orbit? A.) By its special propulsion engine. B) By a conventional rocket engine. C) By firing electrons into the atoms of xenon gas.

D) By accelerating through an electric field.45. Which of the following is NOT true according to this article? A) The author likens the DSI' s navigation system to an electronic brain. B) The DS1 is the first of a new breed of spacecraft. C) The DS1 chief engineer has nothing to lose in such a mission.　D) The DS1' s power system used to be the dream of scientists.

Jogging has become the most popular individual sport in America. It has become commonplace to see people of all ages running along city streets, in parks and along special jogger's trails that have been built in some cities. Many theories, even some mystical ones, have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap, quick and efficient way to maintain (or achieve) physical fitness. The most useful sort of exercise is exercise that develops the heart, lungs, and circulatory systems. If these systems are fit, the body is ready for almost any sport and for almost any sudden demand made by work or emergencies. One can train more specifically, as by developing strength for weight-lifting or the ability to run straight ahead for short distances with great power as in football, but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body. It is worth nothing that this sort of exercise is the only kind that can reduce heart disease, the number one cause of death in America. Only one sort of equipment is needed--a good pair of shoes. Physicians advise beginning joggers not to try to run in a tennis or gym shoes. Many design advances have been made in only the last several years that make an excellent running shoe indispensable if a runner wishes to develop as quickly as possible, with as little chance of injury as possible. A good running shoe will have a soft pad for absorbing shock, as well as a slightly built-up heel and a full heel cup that will give the knee and ankle more stability. A wise investment in good shoes will prevent blisters and foot, ankle, and knee injuries and will enable the wearer to run on paved or soft surfaces. No other special equipment is needed; you can jog in any clothing you desire, even your street clothes. Many joggers wear expensive, flashy warm-up suits, but just as many wear a simple pair of gym shorts and a T-shirt. In fact, many people just jog in last year's clothes. In cold weather, several layer of clothing are better than one heavy sweater or coat. If joggers are wearing several layers of clothing, they can add or subtract layers as conditions change. It takes surprisingly little time to develop the ability to run. The American Jogging Association has a twelve-week program designed to move from a fifteen-minute walk (which almost anyone can manage who is in reasonable health) to a thirty-minute run. A measure of common sense, a physical examination, and planned schedule are all it takes.51. The main purpose of this passage is to _______. A) discuss jogging as a physical fitness program B) describe the type of clothing needed for jogging C) provide scientific evidence of the benefits of jogging D) distinguish between jogging as a popular fitness program and a specially designed physical exercise
