Each section is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D．You should decide on the best choice and write your answer on the Answer Sheet.Passage 1It remains to be seen whether the reserves of raw materials would be sufficient to supply a world economy which would have grown by 500 per cent. Southeast Asia alone would have an energy consumption five times greater than that of Western Europe in 1970. Incidentally, if the underdeveloped countries started using up pet petrol at the same rate as the industrialized areas, then world reserves would already be exhausted by 1985.All this only goes to show just how important it is to set up a plan to conserve and divide up fairly natural resources on a world－wide scale．This is a matter of life and death because world population is exploding at an incredible rate．By the middle of the next century population will expand every year by as much as it did in the first 1500 years after Christ. In the southern, poor part of the globe, the figures are enough to make your hair stand on end．Even supposing that steps are taken to stabilize world population in the next fifty years, the number of inhabitants per square kilometer will increase by from 4 in the United States to 140 in Southeast Asia．What can we do about it?In the first hypothesis we do nothing．By the year 2000, the southern parts of the world would then have a population greater than the total world population today. Calcutta would have 60 million inhabitants. It is unthinkable．Alternatively, we could start acting tight now to bring births under control within fifteen years ago so that population levels off．Even then the population in the southern areas would not stop growing for seventy－five years.71．By the year 2000 the world economy will have grown by ______.A．500 per centB．100 per centC．four timesD．an unknown amount72．World petrol reserves will be used up by 1985 if ______.A．Western European consumption continues to expandB．Southeast Asia does not limit its consumptionC．underdeveloped countries start to use petrol at the same rate as Western EuropeD．World population continues to expand73．If we took effective measures right now, the world’s population _________.A.could stabilize in thirty－five years’ timeB．would not stop growing for seventy－five yearsC．would stop growing in about fifteen years’ time from nowD.could stabilize in about seventy－five years’ time74．The author suggests in the passage that _________.A．world petrol supplies will have been exhausted by 1985B．we need to use natural resources carefully and divide them up equallyC．to slow down the economic growth in developed countries might be a best policyD．raw materials will not be enough for the world economy in 200075．The purpose of the author in writing this passage is to _________.A．urge people to start taking action right awayB．tell people about the astounding rate of population growthC．describe the problems the world will be faced withD．give an account of the relationship between population growth and industryPassage 2Why do some new products succeed, bringing millions of dollars to innovative companies, while others fail, with great losses? The answer is not simple, and certainly we cannot say that “good” products succeed while “bad” products fail. Many products that function well and seem to meet consumer needs have fallen by the wayside．Sometimes, virtually identical products exist in the market at the same time with one emerging as profitable while the other fails.McNeal Laboratories’ Tylenol has become successful as an aspirin substitute, yet Bristol－Meyers entered the test market at about the same time with Neotrend, also a substitute for aspirin, which quickly failed．The nature of the product is a factor in its success or failure, but the important point is the consumer’s perception of the products need－satisfying capability. Any new product conception should be aimed at meeting a customer need, and the introductory promotion should seek to communicate that need satisfying quality and motivate the customer to try the product. Often, attitude change is involved, and, in the extreme, changes in life－style may be sought.Here the company walks a tightrope．A new product is more likely to be successful if it represents a truly novel way of solving a customer problem, but this very newness, if carried too far, may asked the customer to learn new behavior patterns. The customer will make the change if the perceived benefit is sufficient, but inertia is strong and consumers will often not go to the effort that is required．During the late sixties and early seventies Bristol－Meyers met with new product failures that exemplify both of these problems. In 1967 and 1968 the company entered the market with a $5 million advertising campaign for Fact toothpaste, and an $11 million campaign to promote Resolve．Both products failed quickly, not because they didn’t work or because there was no consumer need, but apparently because consumers just could see no reason to shift from an already satisfactory product to a different one that promised no new benefit.76．The first sentence of first paragraph is a question, to which, the answer is _______.A．that the good products succeed while the bad failB．that the “good” are not really good but the “bad” are actually badC．that new products will succeed if they function well and fail if they don’tD．not given in the paragraph77．What are Tylenol and Neotrend?A．They are names of two drug manufacturers.B．They are probably two brands of medicine which serve as a substitute for aspirin.C．Tylenol is a drug manufacturer whereas Neotrend is a new substitute medicine for aspirin.D．They are probably the names of two laboratories.78．The success or failure of a product seems to be determined by a number of factors, one of which, the author emphasizes, is the consumer’s perception of the product’s _______.A．quality and priceB．usefulness and durabilityC．need－satisfying capabilityD．appearance and inner packing79．What does the author mean when he says “the company walks a tightrope” （see sentence 1, paragraph 3）?A．The company has both the chance to succeed and to fail in dealing in a new product.B．The company has to study the customer’s behavior before a new product is introduced．C．The company has to find a new way to solve customer’s problems before a new product is put on the market.D．The company has to make a great effort to overcome the customer’s intertia．80．Bristol－Meyers failed in promoting Fact toothpaste and Resolve because _____.A．these products were too expensive as compared with their direct competitorsB．both products failed to meet the customers’ needC．the customers could see no sense of a radica1 change of their habitsD．the company forgot an English saying: “You cannot teach an old dog new tricks”Passage 3The more women and minorities make their way into the ranks of management, the more they seem to want to talk about things formerly judged to be best left unsaid．The newcomers also tend to see office matters with a fresh eye, in the process sometimes coming up with critical analyses of the forces that shape everyone’s experience in the organization.Consider the novel views of Harvey Coleman of Atlanta on the subject of getting ahead．Coleman is black．He spent 11 years with IBM, half of them working in management development, and now serves as a consultant to the likes of AT&T, Coca－Cola, Prudential, and Merch．Coleman says that based on what he’s seen at big companies, he weighs the different elements that make for long－term career success as follows: performance counts a mere 10％; image, 30％; and exposure, a full 60％.Coleman concludes that excellent job performance is so common these days that while doing your work well may win you pay increases, it won’t secure you the big promotion. He finds that advancement more often depends on how many people know you and your work, and how high up they are．Ridiculous beliefs? Not to many people, especially many women and members of minority races who, like Coleman, feel that he scales have dropped from their eyes. “Women and blacks in organizations work under false beliefs,” says Kaleel Jamison, a New York－based management consultant who helps corporations deal with these issues. “They think that if you work hard, you’ll get ahead – that someone in authority will reach down and give you a promotion.” She adds, “Most women and blacks are so frightened that people think they’ve gotten ahead because of their sex or color that they play down their visibility.” Her advice to those folks: learn the ways thatwhite males have traditionally used to find their way into the spotlight.81．According to the passage, “things formerly judged to be best left unsaid” （Lined 3, Pare．1）probably refers to “______”.A.criticisms that shape everyone’s experienceB．the opinion which contradict the established beliefsC．the tendencies that help the newcomers to see office matters with a fresh eyeD．the ideas which usually come up with new ways of management in the organization82．To achieve success in your career, the most important factor, according to the passage, is to _____.A．let your superiors know how good you areB．project a favorable image to the people around youC．work as a consultant to your superiorsD．perform well your tasks given by your superiors83．The reason why women and blacks play down their visibility is that they ______.A．know that someone in authority will reach down and give them a promotionB．want to give people the impression that they work under false beliefsC．don’t want people to think that their promotions were due to sex or colorD．believe they can get promoted by reason of their sex or color84．The author is of the opinion that Coleman’s beliefs are ________.A．biasedB．popularC．insightfulD．superficial85．The best title for this passage would be ________.A．Role of Women and Minorities in ManagementB．The Importance of Being VisibleC．Job Performance and AdvancementD．Sex and Career SuccessPassage 4Geologists have been studying volcanoes for a long time．Though they have learned a great deal, they still have not discovered the causes of volcanic action, they know that the inside of earth is very hot, but they are not sure exactly what causes the great heat. Some geologists have thought that the heat is caused by the great pressure of the earth’s outer layers. Or the heat may be left from the time when the earth was formed．During the last sixty years scientists have learned about radium, thorium, and other radioactive elements. These give out the heat all the time as they change into other elements. Many scientists now believe that much of the heat inside the earth is produced by radioactive elements.Whatever the cause of the heat may be, we do know that the earth getter hotter the farther down we dig．In deep mines and oil wells the temperature rises about IF. for each 50 feet. At this rate the temperature 40 miles below the earth’s surface would be over 4000 F. This is much hotter necessary to melt rock．However, the pressure of the rock above keeps most materials from melting at their usual melting points. Geologists believe that the rock deep in the earth may be plastic, or puttylike．In other words, the rock yields slowly to pressure but is not liquid．But if some changes in the earth’s crust releases the pressure, the rock melts. Then the hot, liquid rock can move up toward the surface．When the melted rock works its way close to the earth’s crust, a volcano may be formed．The melted rock often contains steam and other gases under great pressure．If the rock above gives way, the pressure is released．Then the sudden expansion of the gases causes explosions. These blow the melted rock into pieces of different sizes and shoot them high in the air．Here they cool and harden into volcanic ash and cinders. Some ofthis materials falls around the hole made in the earth’s surface．The melted rock may keep on rising and pour out as lava．In this way, volcanic ash, cinders, and lava build up the cone－shaped mountains t that we call volcanoes.86．This passage mainly deals with the ______.A．A. causes of volcanic actionB．formation of volcanoesC．results of volcanic actionD．work of geologists87．The cause for the heat in interior of the earth is _____.A．radioactive elementsB．the great pressure of the earthC．not mentioned in the passageD．the heat remaining from the formation of the earth88．From the information given in the passage, most minerals would melt ____.A．A. at 400 F, 5000 feet above sea levelB．at 400F, 5000 feet below sea levelC．at 4000F, at sea levelD．with the pressure of the rock above89．From the passage we know that “thorium”（para．1）may be _____.A．volcanoB．radioactive elementC．the earth’s out layerD．heat inside the earth90．The main idea of the last paragraph is _____.A．what causes explosionsB.cause of volcanoesC．formation of volcanoes at earth’s surfaceD．melted rockPartⅤTranslation. （4’* 5 ＝20’）91．所有想制止战争的努力都失败了。

following passageFrom the very beginning of school we make books and reading a constant source of possible failure and public humiliation.When children are little,we make them read aloud before the teacher and other children,so that we can be sure they "know"all the words they are reading.This means that when they don't know a word,they are going to make a mistake,right in front of everyone.After having taught fifth-grade classes for four years,I decided to try at all costs to rid them of their fear and dislike of books,and to get them to read oftener and more adventurously.One day soon after school had started,I said to them,"Now I'm going to say something about reading that you have probably never heard a teacher say before.I would like you to read a lot of books this year,but I want you to read them only for pleasure.I am not going to ask you questions to find out whether you understand the books or not.If you understand enough of a book to enjoy it and want to go on reading it,that's enough for me.school where she had ha The children sat stunned and silent.Was this a teacher talking?One girl,who had just come to us from Also I’m not going to ask you what words mean."a d a very hard time,looked at me steadily for a long time after I had finished.Then,still looking at me,she said slowly and seriously,"Mr.Holt,do you really mean that?"I said just as seriously,"I mean every word of it."During the spring she really astonished me.One day,she was reading at her desk.From a glimpse of the illustrations,I thought I knew what the book was.I said to myself,"It can't be,"and went to take a closer look.Sure enough,she was reading Moby Dick,in edition with woodcuts.I said,"Don't you find parts of it rather heavy going?"She answered,“Oh,sure,but I just skip over those parts and go on to the next good part."This is exactly what reading should be and in school so seldom is an exciting,joyous adventure.Find something,dive into it,take the good parts,skip the bad parts,get what you can out of it,go on to something else.How different is our mean-spirited,picky insistence that every child get every last little scrap of "understanding"that can be dug out of a book.16.According to the passage,children's fear and dislike of books may result fromA.reading little and thinking littleB.reading often and adventurouslyC.being made to read too muchD.being made to read aloud before others17.This teacher in the passage told his students to readA.for enjoymentB.for knowledgeC.for a larger vocabularyD.for higher scores in exams 18.Upon hearing the teacher's talk,the children probably felt thatA.it sounded stupidB.it was not surprising at allC.it sounded too good to be trueD.it was no different from other teachers'talk19.Which of the following statements about the girl is TRUE according to the passage?A.She skipped over those easy parts while reading.B.She had a hard time finishing the required reading tasks.C.She learned to appreciate some parts of the difficult books.D.She turned out to be a bad student after coming to this school.20.From this teacher's point of view,A.children cannot tell good parts from bad parts while readingB.children should be left to decide what to read and how to readC.reading is never a pleasant and inspiring experience in schoolD.reading involves understanding every little piece of informationSection B (20points)Directions:In this section there is a passage with ten blanks.You are required to select one word for each blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices.Each choice in the bank is identified by a letter.Please mark the corresponding letter on the “Don’t take many English

may not use any of the words in the bank more than once.”Sound 21?Many of us have heard suggestions like these put forward by parents or others close to us.Such comments often seem quite reasonable.Why,then,should suggestions like these be 22with caution?The Making your own decisions does not mean that you should 25the suggestions of others.For instance,your parents do have their own unique experiences that may make their advice helpful,and 26participated in a great deal of your personal history,they may have a clear view of your 27and weaknesses.Still their views are not necessarily accurate.They may still see you as a child,in need of care and protection.Or they may see only your strengths.Or,in some 28cases,they may focus only on your flaws and 29One of the worst reasons to follow a particular path in life is that other people want you to.Decisions that affect your life should be your decisions—decisions you make 24you’ve considered various alternatives and
