Read the passages carefully and choose the best answer to each of the questions. Put your choice in the brackets on the left.(10 points)Text 1There are a great many careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in great area at a glance, people who perhaps do not know too much about any one field. There is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgments. We can call these people “generalists.” And these “generalists” are particularly needed for positions in administration, where it is their job to see that other people do the work, where they have to plan for other people, to organize other people’s work, to begin it and judge it.The sp ecialist understands one field; his concern is with technique and tools. He is a “trained” man; and his educational background is properly technical or professional. The generalist -- and especially the administrator -- deals with people; his concern is wi th leadership, with planning, and with direction giving. He is an “educated” man; and the humanities are his strongest foundation. V ery rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in particular field. Any organization needs both kinds of people, though different organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly.Your first job may turn out to be the right job for you -- but this is pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.26. There is an increasing demand for ________.[A] all round people in their own fields[B] people whose job is to organize other people’s work[C] generalists whose educational background is either technical or professional[D] specialists whose chief concern is to provide administrative guidance to others27. The specialist is ________.[A] a man whose job is to train other people[B] a man who has been trained in more than one fields[C] a man who can see the forest rather than the trees[D] a man whose concern is mainly with technical or professional matters28. The administrator is ________.[A] a “trained” man wh o is more a specialist than a generalist[B] a man who sees the trees as well as the forest[C] a man who is very strong in the humanities[D] a man who is an “educated” specialist29. During your training period, it is important ________.[A] to try to be a generalist[B] to choose a profitable job[C] to find an organization which fits you[D] to decide whether you are fit to be a specialist or a generalist30. A man’s first job ________.[A] is never the right job for him[B] should not be regarded as his final job[C] should not be changed or people will become suspicious of his ability to hold any job[D] is primarily an opportunity to fit himself for his final jobTest 2At the bottom of the world lies a mighty continent still wrapped in the Ice Age and, until recent times, unknown to man. It is a great land mass with mountain ranges whose extent and elevation are still uncertain. Much of the continent is a complete blank on our maps. Man has explored, on foot, less than one per cent of its area. Antarctica differs fundamentally from the Arctic regions. The Arctic is an ocean, covered with drifting packed ice and hemmed in by the land masses of Europe, Asia, and North America. The Antarctic is a continent almost as large as Europe and Australia combined, centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world -- the Atlantic, Pacific, and Indian Oceans.The continental ice sheet is more than two miles high in its centre, thus, the air over the Antarctic is far more refrigerated than it is over the Arctic regions. This cold air current from the land is so forceful that it makes thenearby seas the stormiest in the world and renders unlivable those regions whose counterparts at the opposite end of the globe are inhabited. Thus, more than a million persons live within 2,000 miles of the North Pole in an area that includes most of Alaska, Siberia, and Scandinavia -- a region rich in forest and mining industries. Apart from a handful of weather stations, within the same distance of the South Pole there is not a single tree, industry, or settlement.31. The best title for this selection would be ________.[A] Iceland[B] Land of Opportunity[C] The Unknown Continent[D] Utopia at Last32. At the time this article was written, our knowledge of Antarctica was ________.[A] very limited[B] vast[C] fairly rich[D] nonexistent33. Antarctica is bordered by the ________.[A] Pacific Ocean[B] Indian Ocean[C] Atlantic Ocean[D] All three34. The Antarctic is made uninhabitable primarily by ________.[A] cold air[B] calm seas[C] ice[D] lack of knowledge about the continent35. According to this article ________.[A] 2,000 people live on the Antarctic Continent[B] a million people live within 2,000 miles of the South Pole[C] weather conditions within a 2,000 mile radius of the South Pole make settlements impractical[D] only a handful of natives inhabit AntarcticaSection IV: Structure and VocabularyFill in the blanks with the words which best complete the sentences.

Directions: Each of the passages below is followed by some questions. For each question four answers are given. Read the passages carefully and choose the best answer to each question. Put your choice in the ANSWER SHEET.(15%) Passage 1It was a normal day in the life of the American Red Cross in Greater New York. First, part of a building on West 140th Street, in Harlem, fell down. Beds tumbled through the air, people slid out of their apartments and onto the ground, three people died, and the Red Cross was there, helping shocked residents find temporary shelter, and food and clothing. Then it was back downtown for that evening’s big fund-raiser, the Eleventh Annual Red Cross Award Dinner Dance, at the Pierre. “That’s why I have bad hair tonight,” said Christopher Peake, a Red Cross spokesman who had spent much of the day at the Harlem scene, in the drizzling rain. He was now in a tuxedo, and actually his hair didn’t look so bad, framed by a centerpiece of tulips and jonquils, and perhaps improved by subdued lighting from eight crystal chandeliers.Definitely not having a bad-hair night was Elizabeth Dole, the wife of Senator Robert Dole and the president of the American Red Cross. President Dole has chestnut-colored Republican hair, which was softly coifed, and she was wearing a fitted burgundy velvet evening suit (“Someone made it for me! I love velvet.” she exclaimed, in her enthusiastic, Northern Carolina hostess voice) and sparkling drop earrings. Of course, she hadn’t been standing in the rain in Harlem; she had just flown up on the three-o’clock shuttle from Washington. Dole is extremely pretty, with round green eyes and a full mouth and a direct personality. She tilts her head attentively when she listens. She was the recipient of the evening’s award; previous award winners have included Alice Tully, Princess Yasmin Asa Khan,... and, most recently, Brooke Astor. Not exactly a sequence at the end of which you would expect to find Elizabeth Dole, but award givers are famous for having political instincts as well as philanthropic ones.Surrounded by the deep-blue swags and golden draperies of the ballroom were more than thirty-five dinner tables set with groupings of candles and floral centerpieces and Royal Doulton china. American Express was there. So were Bristol-Myers Squibb; Coopers & Lybrand; the New York Times Company; Union Bank of Switzerland; Chemical Bank; New York Life;... and Price Waterhouse. The actress Arlene Dahl, with her rather red hair and her bearded husband, presided over one table. Otherwise, it was a typical, faceless, captain-of-industry fund raiser (no models! no stars!), of which there seems to be at least one every night in New York City. It was not a society night, but still the evening raised four hundred and thirty thousand dollars.26.From what we read we can infer that “it was a normal day in the life of the American Red Cross in Greater New York” means its staff .A. deal with the fail of houses in the city every dayB. are busy helping people who suffer from disasters every dayC. work during the day and to have banquet in the evening every dayD. go to Harlem, the poorest district of New York, every day and help people there27.The fund-raiser mentioned in the passage refers to .A. Robert DoleB. Elizabeth DoleC. the Eleventh Annual Red Cross Award Dinner DanceD. all the business companies attending the Dinner Dance28.Christopher Peake’s hair didn’t look so bad because .A. he was wearing a handsome tuxedoB. he was wearing tulips on his suitC. he was seen among flowersD. he was sitting near flowers and in very soft light29.Elizabeth Dole was ,A. the president of the American Red Cross and acted at the Dinner as a North Carolina hostessB. a republican and wife of the president of the American Red CrossC. the president of the American Red Cross and its main representative at the Annual Dinner DanceD. born in North Carolina, became an air-hostess and later married Senator Robert Dole30.The presence of an actress at the Dinner made the fund raising .A. less impersonalB. a typical fund-raising eventC. less personalD. more business-likePassage 2For laymen ethnology is probably the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentation in laboratories.The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers certainly not scientists, since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can’t be, or the homing of animals over long distances, or even details of spontaneous family relationships. Since these never can be reproduced in a laboratory, are they then not worth knowing about?The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually, and released. Motion pictures, often in color, provide permanent records of their subsequent activities. Recording of the animals’ voices by electrical sound equipment is consideredessential, and the most meticulous notes are kept of all that occurs. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other’s observations right there in the field.Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or features which distinguish any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying “the whole sequence of acts which constitute an animal’s behavior.” In abridged dictionaries ethnology is sometimes defined simply as “the objective study of animal behavior,” and ethnologists do emphasize their wish to eliminate myths.31.In the first sentence, the word “laymen” means .A. people who stand asideB. people who are not trained as biologistsC. people who are amateur biologistsD. people who love animals32.According to the passage, ethnology is .A. a new branch of biologyB. an old Greek scienceC. a pseudo-scienceD. a science for amateurs33.“The field workers have handicaps in winning respect for themselves.” This sentence means .A. ethnologists when working in the field are handicappedB. ethnologists have problems in winning recognition as scientistsC. ethnologists are looked down upon when they work in the fieldD. ethnologists meet with lots of difficulties when doing field work34.According to the explanation of the scientific rule of experiment in the passage, “hard-and-fast” means experiment procedures .A. are difficult and quick to followB. must be carried out in a strict and quick wayC. must be followed strictly to avoid false and loose resultsD. hard and unreasonable for scientists to observe35.The meaning of the underlined words in “the details of spontaneous family relationships” can be expressed as .A. natural family relationshipsB. quickly occurring family relationshipsC. animals acting like a natural familyD. animal family behavior that cannot be preplanned or controlledPassage 3The single greatest shift in the history of mass-communication technology occurred in the 15th century and was well described by Victor Hugo in a famous chapter of “NotreDame de Paris”. It was a cathedral. On all parts of the giant building, statuary and stone representations of every kind, combined with huge windows of stained glass, told the stories of the Bible and the saints, displayed theintricacies of Christian theology, adverted to the existence of highly unpleasant demonic winged creatures, referred diplomatically to the majesties of political power, and, in addition, by means of bells in bell towers, told time for the benefit of all of Paris and much of France. It was an awesome engine of communication.Then came the transition to something still more awesome. The new technology of mass communication was portable, could sit on your table, and was easily replicable, and yet, paradoxically, contained more information, more systematically presented, than even the largest of cathedrals. It was the printed book. Though it provided no bells and could not tell time, the over-all superiority of the new invention was unmistakable.In the last ten or twenty years, we have been undergoing a more or less equivalent shift—this time to a new life as a computer-using population. The gain in portability, capability, ease, orderliness, accuracy, reliability, and information-storage over anything achievable by pen scribbling, typewriting, and cabinet filing is recognized by all. The progress for civilization is undeniable and, plainly, irreversible. Yet, just as the book’s triumph over the cathedral divided people into two groups, one of which prospered, while the other lapsed into gloom, the computer’s triumph has also divided the human race.You have only to bring a computer into a room to see that some people begin at once to buzz with curiosity and excitement, sit down to conduct experiments, oh and ah at the boxes and beeps, and master the use of the computer or a new program as quickly as athletes playing a delightful new game. But how difficult it is—how grim and frightful for the other people, the defeated class, whose temperament does not naturally respond to computers. The machine whirrs and glows before them and their faces twitch. They may be splendidly educated, as measured by book-reading, yet their instincts are all wrong, and no amount of manual-studying and mouse-clicking will make them right. Computers require a sharply different set of aptitudes, and, if the aptitudes are missing, little can be done, and misery is guaranteed.Is the computer industry aware that computers have divided mankind into two new, previously unknown classes, the computer personalities and the non-computer personalities? Yes, the industry knows this. Vast sums have been expended in order to adapt the computer to the limitations of non-computer personalities. Apple’s Macintosh, with its zooming animations and pull-down menus and little pictures of file folders and watch faces and trash cans, pointed the way. Such seductions have soothed the apprehensions of a certain number of the computer-averse. This spring, the computer industry’s efforts are reaching a culmination of sons. Microsoft, Bill Gates’ giant corporation, is to bring out a program package called Microsoft Bob, designed by Mr. Gates’ wife, Melinda French, and intended to render computer technology available even to people who are openly terrified of computers. Bob’s principle is to take the several tasks of operating a computer, rename them in a folksy style, and assign to them the images of an ideal room in an ideal home, with furniture and bookshelves, and with chummy cartoon helpers (“Friends of Bob”) to guide the computer user over the rough spots, and, in that way, simulate an atmosphere that feels nothing like computers.36. According to this passage, which of the following statements is NOT true?A. It is because the cathedral of Notre—Dame in Paris had many bell-towers and could tell time to people that the writer regards it as an engine of mass communication.B. From cathedrals to books to computers the technology of communication has become more convenient, reliable and fast.C. Every time when a new communication means triumphed over the old, it divided mankind into two groups.D. Computer industry has been trying bard to make people accept computers.37.The printed book is more progressive than the cathedral as a communication means, because .A. it could sit on your table and did no longer tell timeB. it was more reliable and did not tell the stories of saints and demonsC. it was small, yet contained more informationD. it did not flatter religious and political power38.The word “awesome” in the passage means .A. frighteningB. causing fear and respectC. amazingly newD. awful39.People who feel miserable with computers are those .A. who love reading hooks and writing with a pen or a typewriterB. who possess the wrong aptitudes of disliking and fearing new thingsC. who have not been trained to use computersD. who are born with a temperament that does not respond to computers40.Melinda French designed Microsoft Bob which was to ease the misery of computer users by .A. making users feel that they are not dealing with machinesB. making the program more convenient and cartoon-likeC. adding home pictures to the program designD. renaming the computer tasks in a folksy styleⅡ. Directions: Read the following passage carefully and then paraphrase the numbered and underlined parts. (“Paraphrase” means to explain the meaning in your own English.) (15%)Charm is the ultimate weapon, the supreme seduction, against which there are few defenses. If you’ve got it, you need almost nothing else, neither money, looks, nor pedigree. (41) It is a gift—only given to give away, and the more used the more there is. It is also a climate of behavior set for perpetual summer and controlled by taste and tact.Real charm is dynamic, an enveloping spell which mysteriously enslaves the senses. It is an inner light, fed on reservoirs of benevolence which well up like a thermal spring. It is unconscious, often nothing but the wish to please, and cannot be turned on and off at will.(42) You recognize charm by the feeling you get in its presence. You know who has it. But can you get it too? Probably, you can’t, because it’s a quickness of spirit, an originality of touch you have to be born with. Or it’s something thatgrows naturally out of another quality, like the simple desire to make people happy. Certainly, charm is not a question of learning tricks, like wrinkling your nose, or having a laugh in your voice, or gaily tossing your hair out of your dancing eyes.(43) Such signs, to the nervous, are ominous warnings which may well send him streaking for cover. On the other hand, there is an antenna, a built-in awareness of others, which most people have, and which care can nourish.But in a study of charm, what else does one look for? Apart from the ability to listen rarest of all human virtues and most difficult to sustain without vagueness apart from warmth, sensitivity, and the power to please, what else is there visible?(44) A generosity, I suppose, which makes no demands, a transaction which strikes no bargains, which doesn’t hold itself back till you’ve filled up a test-card making it dear that you’re worth the trouble. Charm can’t withhold, but spends itself willingly on young and old alike, on the poor, the ugly, the dim, the boring, on the last fat man in the comer. (45) It reveals itself also in a sense of ease, in casual but perfect manners, and often in a physical grace which springs less from an accident of youth than from a confident serenitv of mind. Any person with this is more than just a popular fellow, he is also a social healer.Part Ⅲ Cloze TestDirections:Fill in each numbered blank in the following passage with ONE suitable word to complete the passage. Put your answers in the ANSWER SHEET. (10%) One way of improving one’s writing is to get into the habit of keeping a record of your observations, of storing 46 in a notebook or journal. You should make note on your experiences and on your 47 of everyday life so that they are preserved. It is sad 48 to be able to retrieve a lost idea that seemed brilliant when it flashed across your 49 , or a forgotten fact that you need to make a point in an argument or to illustrate a conclusion.The journal habit has still 50 value. Just 51 you need to record observations—he material for writing, you need to practice putting thoughts on paper. Learning to write is more like learning to ski 52 it is like studying calculus or anthropology. Practice helps you discover ways to improve. Writing down ideas for your own use forces you to examine them. Putting thoughts on paper for someone else to read 53 you to evaluate not 54 the content what you say but also the expression 55 you say it. Many raters have benefited from this habit.Part Ⅳ ProofreadingDirections: This part consists of a short passage. In this passage, there are altogether 20 mistakes, one in each underlined sentence or part of a sentence. You may have to change a word, add a word or just delete a word. If you change a word, cross it out with a slash (\) and write the correct word. If you add a word, write the missing word between the words (in bracket) immediately before and after it. If you delete a word, cross it out with a slash (\). Put your answers in the ANSWER SHEET.(20%)Examples:eg.1.(56) The meeting begun 2 hours ago.Correction in the ANSWER SHEET:(56) begun→beganeg.2.(57) Scarcely they settled themselves in their seats in the theatre when the curtain went up.Correction in the ANSWER SHEET:(57) (Scarcely) had (they)eg.3.(58) Never will I not do it againCorrection in the ANSWER SHEET:(58) not(56) “Humanism” has used to mean too many thing, to be a very satisfactory term. (57) Nevertheless, and in the lack of a better word, (58) I shall use it here to explain for the complex of attitudes which this discussion has undertaken to defend.(59) In this sense a humanist is anyone who reiects the attempt to describe or account of man wholly on the basis of physics, chemistry, and animal behavior. (60) He is anyone who believes that will, reason, and purpose are real and significant: that value and justice are aspects of a reality called good and evil and rests upon some foundation other than custom; (61) that consciousness is so far from a mere epiphenomenon that it is the most tremendous of actualities; (62) that the unmeasured, may be significant; or to sum it all up; (63) that those human realities which sometimes seem to exist only in human mind are the perceptions of the mind.(64) He is, in other words, anyone who says that there are more things in heaven and earth than those dreamed of in the positivist philosophy.(65) Originally, to be sure, the term humanist meant simply anyone who thought the study of ancient literature his chief concern. Obviously it means, as I use it, very much more. (66) But there remains nevertheless a certain connection between the aboriginal meaning and that I am attempting to give it, (67) because those whom I describe as humanists usually recognize that literature and the arts have been pretty consistently “on its side” and (68) because it is often literature that they turn to renew their faith in the whole class of truths which the modem world has so consistently tended, to dismiss as the mere figments of a wishful thinking imagination.(69) Insofar as this modern world gives less and less attention to its literary past, insofar as it dismisses that past as something outgrow and (70) to be discarded as much as the imperfect technology contemporary with it has been discarded, (71) just to that extent it facilitate the surrender of humanism to technology. (72) The literature is to be found, directly expressed or (73) more often indirectly implied, the most effective correction to the views now most prevalent among the thinking and unthinking.(74) The great imaginative writers present a picture of human nature and of human life which carries conviction and thus giving the lie to all attempts to reduce man to a mechanism. Novels and poems, and dramas are so persistently concerned with the values which relativism rejects that one might even define literature as the attempt to pass value judgments upon representations of human life. (75) More often than not those of its imaginative persons who fail to achieve power and wealth are more successful than those who do not—by standards which the imaginative writer persuades us to accept as valid.Part Ⅴ WritingDirections: Write a short composition of about 250 to 300 words on the topic given below.(15%)Topic: What is the most urgent issue facing the world people in the 21st century? State your reasons.真题11. C2. D3. B4. A5. D6. D7. C8. C9. C 10. C 11. B 12. B 13. D 14. B 15. A 16. B 17. B 18. D 19. C 20. A 21. D 22. A 23. C 24. A 25. C 26. B 27. C 28. D 29. C 30. A 31. B 32.
