For each of them there are 4 choices marked A,B,C and D. Y ou should decide on the best answer or the best choice to complete the statement and write the corresponding letter on the ANSWER SHEET.(40 points, 2 points each)Passage 1There are two basic differences between the large and the small enterprises. In the small enterprise3you operate primarily through personal contacts. In the large enterprise you have established “policies,”“channels”of organization, and fairly rigid procedures. In the small enterprise you have, moreover, immediate effectiveness in a very small area. Y ou can see the effect of your work and of your decisions right away, once you are a little above the ground floor. In the large enterprise even the man at the top is only part of a big machine. To be sure, his actions affect a much greater area than the actions and decisions of the man in the small organization, but his effectiveness is remote, indirect, and difficult to see at first sight. In a small and even in a middle-sized business you are normally exposed to all kinds of experiences, and expected to do a great many things without too much help or guidance. In the large organization you are normally taught one thing thoroughly. In the small one the danger is of becoming a jack-of-all-trades and master of none. In the large one it is of becoming the man who knows more and more about less and less.There is one other important thing to consider: do you get a deep sense of satisfaction from being a member of a well-known organization--General Motors, the Bell Telephone System, the government? Or is it more important to you to be a well-known and important figure within your own small pond? There is a basic difference between the satisfaction that comes from being a member of a large, powerful, and generally known organization, and the one that comes from being a member of a family; between impersonal grandeur and personal —often much too personal —intimacy; between life in a small office on the top floor of a skyscraper and life in a crossroads gas station.21.It can be inferred from the first paragraph that in a large enterprise ____.A. new technology is employed quicklyB. all people work efficientlyC. one's effectiveness is felt very slowlyD. one can get promotion easily22.Generally speaking, the person working in a large enterprise ____.A. has to deal with a great many thingsB. knows how everything is going on around himC. acquires increasingly thorough knowledge within a limited fieldD. feels more secure than the one employed by a small enterprise23.In the second paragraph, the writer mentions “your own small pond”to refer to ____.A. a top leader in a larger enterpriseB. a manager of a small enterpriseC. a large enterpriseD. a small enterprise24.According to the information provided in the passage, if you are interested in personal intimacy, you should work ____.4A. for General MotorsB. for the Bell Telephone SystemC. in a department in the governmentD. in a crossroads gas station25.The writer of this passage ____.A. compares the large and the small enterprises objectivelyB. obviously prefers to work for a large enterpriseC. intends to show the advantages of working in a small businessD. explains the disadvantages of being a top leader in a large businessPassage 2In the old days, when a glimpse of stockings was looked upon as something far too shocking to distract the serious work of an office, secretaries were men.Then came the First World War and the male secretaries were replaced by women. A man's secretary became his personal servant ,charged with remembering his wife's birthday and buying her presents; taking his suits to dry-cleaners; telling lies on the telephone to keep people he did not wish to speak to at bay; and of course, typing and filing and taking shorthand.Now all this may be changing again .The microchip (集成块) and high technology is sweeping the British office, taking with it much better of the routine clerical work that secretaries did.“Once office technology takes over generally, the status of the job will rise again because it will involve only the high-powered work—and then men will want to do it again.”That was said by one of the executives(male) of one of the biggest secretarial agencies in this country.What he has predicted is already under way in the U.S.Once high technology has made the job of secretary less routine, will there be a male takeover? Men should beware of thinking that they can walk right into better jobs. There are a lot of women secretaries who will do the job as well as they—not just because they can buy negligees(妇女长睡衣) for the boss's wife, but because they are as efficient and well-trained to cope with word processors and computers as men.26.Before 1914 female secretaries were rare because they ______.A. were less efficient than menB. were not as serious as menC. liked stockingsD. would have disturbed other office workers27.Besides fulfilling other duties, a female secretary was expected to _____.5A. be her boss's memoryB. clean her boss's clothesC. do what her boss asked her toD. telephone her boss's wife28.Secrtaries,until recently, had to do a lot of work now done by _____.A. machinesB. other staffC. servantsD. wives29.A secretary in the future will ______.A. be better paidB. have higher statusC. have less work to doD. have more work to do30.The writer believes that before long _____.A. both men and women will be qualified secretariesB. men will be better than machinesC. men will take over women's jobs as secretariesD. women will operate most office machinesPassage 3Clutter is the disease of American writing. We are a society strangling in unnecessary words, circular constructions, pompous frills and meaningless jargon.Who really knows what the average businessman is trying to say in the average business letter? What member of an insurance or medical plan can decipher the brochure that tells him what his costs and benefits are? What father or mother can put together a child's toy—on Christmas Eve or any other eve—from the instructions on the box? Our national tendency is to inflate and thereby sound important. The airline pilot who wakes us to announce that he is presently anticipating experiencing considerable weather wouldn't dream of saying that there's a storm ahead and it may get bumpy. The sentence is too simple—there must be something wrong with it.But the secret of good writing is to strip every sentence to its cleanest components. Every word that serves no function, every long word that could be a short word, every adverb winch carries the same meaning that is already in the verb, every passive construction that leaves the reader unsure of who is doing what—these are the thousand and one adulterants (赘词)that weaken the strength of a sentence. And they usually occur, ironically, in proportion to education and rank.During the late 1960's the president of Princeton University wrote a letter to mollify the alumni after a spell of campus unrest. “Y ou are probably aware,”he began,“that we have been experiencing very considerable potentially explosive expressions of dissatisfaction on issues only6partially related.”He meant that the students had been hassling them about different things. As an alumnus I was far more upset by the president's syntax than by the students' potentially explosive expression of dissatisfaction. I would have preferred the presidential approach taken by Franklin D. Roosevelt when he tried to convert into English his own government's memos, such as this blackout order of 1942:Such preparations shall be made as will completely obscure all Federal buildings and non-Federal buildings occupied by the Federal government during an air raid for any period of time from visibility by reasons of internal or external illumination.“Tell them,”Roosevelt said,“that in buildings where they have to keep the work going to put something across the windows.”31.What is the author's main purpose in writing the passage?A. To show the intellectual level of most Americans.B. To criticize wordy writing.C. To inform readers of the American writing style.D. To describe the best way of communication.32.The reason why the author quotes Roosevelt is to ____.A. provide evidence for the government documentB. reveal the hidden power of wordsC. give an example of the authority's role during the crisisD. show how simply the blackout order could have been stated33.According to the passage, the airline pilot avoids using the word“storm”because the word____.A. may frighten the passengersB. is ambiguousC. is too ordinary.D. sounds important34.The author gives the example of the president of Princeton in order to show that____.A. educated people usually communicate clearlyB. educated people tend to act like leadersC. simplicity is something easily forgotten by leaders or educated peopleD. simplicity is not suitable for the style of leaders or educated people35.Which of the following words is NOT negatively slanted?A. ClutterB. JargonC. DecipherD. BrochurePassage 4When I first considered becoming a college professor, tenure was not an attraction or even an issue. I was drawn to the profession by the work and the environment. Even after earning a Ph.D.,7spending time working in Washington D.C., and finally getting my first teaching job in public administration, I was not particularly concerned with tenure. I now work at a regional institution that requires an attainable balance between teaching, research, and service. I have always been a hard worker and see no reason to stop.But my vision of tenure has changed, I do not want to always by the same kind of professor I am now. Now, I am working on articles, course preparations, learning the details of the curriculum so I can advise students, and building institutional knowledge by serving on university committees. Today, my productivity is high and I focus on “collecting beans,”tomorrow, I would like to focus on quality.Whether tenure can give me the opportunity to focus on quality is questionable, but the idea of longevity is a concept that seems to have broad acceptance in most professions. My friends w ho became lawyers and accountants spend their time talking about becoming partners; medical doctors talk about establishing a practice; civil servants are protected by the merit system. The professionals in these fields serve a probationary period(试用期) and demonstrate competence to attain a certain level of freedom in their fields. After that, we expect that their professionalism can be used to serve society.Are college professors and universities different from lawyers, law firms, and the American Bar Association or doctors, practices, and the American Medical Association? The answer is both yes and no. Rarely does one hear about a professor being brought to court for malpractice. Still, the college professors I know work long hours, serve arduous, poorly-paid probationary periods, are dedicated to their students and their fields and do not want to work in another profession after they have arrived in this one. Thus tenure is often seen as the reward for years of struggle. Tenure, therefore, has become something important to me, specifically as a way to become firmly established in my profession.36.What does “tenure”probably mean in the passage?A. The reward to a lawyer or an accountant for his or her hard work.B. The right to keep one's job at a university until retirement.C. The chance of being promoted to a higher administrative position.D. The possibility of establishing one's own practice after a probationary period.37.By “I do not want to always be the same kind of professor I am now,”the author means that______.A. he is thinking of leaving his present jobB. he does not really enjoy writing articles or preparing for coursesC. he wants to do something more important and worthwhileD. he does not like the teaching environment any more838.In the second paragraph, “collecting beans”is nearest in meaning to ______.A.“making significant contributions”B.“making small achievements”C.“enjoying the rewards of hard work”D.“gaining greater professional competence”39.Which of the following is NOT true according to the passage?A. The writer is not sure that tenure would let him focus on quality.B. Y oung lawyers look forward to sharing the ownership of the firm they work for.C. College professors have small salaries until their probationary period is over.D. College professors may consider working in some other professions if they are not properlyrewarded.40.The writer mentions lawyers and accountants in order to ______.A. explain why he chose teaching as his careerB. illustrate how other professionals view their workC. prove that professors and other professionals have the same idea about qualityD. show that college professors' expectation of job security is reasonableⅢ.SKIMMING AND SCANNINGIn this part there are 3 reading passages followed by 10 questions or unfinished statements. For each of them there are 4 choices marked A,B,C and D. Skim or scan the passages, then decide on the best answer and write the corresponding letter on the ANSWER SHEET.(10 points, 1 point each)Passage 1Nurse Kettle took the river path. Dusk had fallen over the valley and as she descended into it her own footfall sounded unnaturally loud on the firm turf. Thump, Thump, Thump, she went, down the hillside. Were those only her footsteps? She stopped dead, tilted her head and listened. Only occasional rural sounds disturbed the quiet of nightfall. She could actually hear the cool voice of the stream.She did not cross Harper's Bridge but followed a rough path along the right bank of the river, past a group of alders and another of willows, this second group, extending in a sickle-shaped mass from the water's edge into Harper's Meadow, rose up in the dusk. She could smell willow leaves and wet soil. As sometimes happens when we are solitary, she had the sensation of being observed but she was not a fanciful woman and soon dismissed the feeling.“It's turned much cooler,”she thought.A cry of mourning, intolerably loud, rose from beyond the willows and hung on the night air. A9brown bird whirred out of the thicket close to her face and the cry broke and moved again gently in several different directions. It was the howl of a dog. She pushed through the thicket into a clearing by the river and found the body of Colonel Carter with his dog Skip bedside him, mourning him.41.Why did Nurse Kettle suddenly stop?A. She thought she was dying.B. She wondered if she was alone.C. She wanted to hear the sound of the stream.D. She thought she heard a voice.42.Which direction did Nurse Kettle take when she reached Harper’s Bridge?A. She crossed it and continued along the right bank.B. She didn't cross it and turned away from the trees.C. She followed a path through some tress.D. She followed a path by the river bank.43.What caused Nurse Kettle to feel that she was being watched?A. The strange shape in the mist.B. The damp smell of the wet earth.C. A sense of not being alone.D. A drop in the temperature.44.Where did Nurse Kettle discover the body of Colonel Carter?A. In some thick bushes.B. In the river with his dog.C. Among the willow trees.D. In an opening beyond the bushes.Passage 2The idea of “a chain of stores,”buying directly from the manufacturer in large quantities and selling in many different places throughout the country, had its beginning with Woolworth, Kress, Kresge, and others who followed them. They were the forerunners of the large retail chain and department stores. These men had the vision to see that the more the manufacturers produced, the greater would be the saving to the consumer.Frank Woolworth was born in the town of Rodman in New Y ork State, in the year 1855. He had a poverty-stricken childhood, which meant hardly enough to eat, one pair of boots a year, and never a warm coat for the winter. Frank did not like farming. He dreamed of being a railroad engineer. Later, he changed his ambition and wanted to become a merchant.When Frank Woolworth was a young man, apprenticeship was still in existence, particularly in the eastern part of the United States. A boy was taken into a business to learn a trade, or to learn how10to conduct the business. He was considered to be worth very little to the owner during his learning period. Sometimes, the apprentice would be given his board and a room. The businessman felt that he was doing something worthwhile for the young man he took as an apprentice. He reasoned that it was like sending the young man to a school and paying his tuition.Woolworth managed to take a short commercial course which he knew he needed to become a merchant. At first, he was given a small wage of three dollars and fifty cents a week in the firm of Moore and Smith. After a while Woolworth came to the conclusion that while he was not a good salesman, he could trim the store and dress the windows to attract customers. In time, he worked up to six dollars a week. Another merchant offered him ten dollars a week and Woolworth decided that it was enough to marry on. Unfortunately, his new employer was not interested in having his windows dressed. And after a week or two of Woolworth's poor salesmanship, he reduced his wages to eight dollars a week.With a wife to support now, Woolworth decided to try farming. He bought a farm on mortgage and he and his wife raised chickens. But in a short time farming bored him. Besides, Moorc and Smith asked him to return to his job. They found that they needed Woolworth as a window trimmer, to attract customers. When they offered him the job at ten dollars a week, Woolworth went back to working in the store.45.One thing that a store chain can do but an independent storekeeper cannot do is to ______.A. hold salesB. competeC. advertiseD. buy in large quantities46.Frank Woolworth had ability in ______.A. farmingB. salesmanshipC. dressing store windowsD. bargaining47.Woolworth's first ambition was to become ______.A. a farmerB. a railroad engineerC. a merchantD. a designerPassage 3More and more residences, businesses, and even government agencies are using telephone answering machines to take messages or give information or instructions. Sometimes these machines give confusing instructions, or play messages that are difficult to understand. If you make telephone calls, you need to be ready to respond if you get a recording.The most common machine is the type used in residences. If you call a home where there is a telephone answering machine in operation you will hear several rings and then a recorded message that usually says something like this:“Hello. We can't come to the phone right now. If you want us to call you back, please leave your name and number after the beep.”Then you will hear a11“beep,”which is a brief, high-pitched tone. After the beep, you can say who you are, whom you want to speak to, and what number the person should call to reach you, or you can leave a message. Some telephone answering machines record for only 20 or 30 seconds after the beep, so you must respond quickly.Some large businesses and government agencies are using telephone answering machines to provide information on topics about which they receive a large volume of inquires. Using these systems requires you to have a touch-tone phone(a phone with buttons rather than a rotary dial). The voice on the machine will tell you to push a certain button on your telephone if you want information on Topic A, another button for Topic B, and so on. Y ou listen until you hear the topic you want to learn about, and then you push the appropriate button. After making your selection, you will hear a recorded message on the topic.48.In the passage, the writer elaborates on ______.A. the problems of telephone answering machinesB. the beep of the telephone answering machinesC. touch-tone phonesD. how to use telephone answering machines49.“Beep”is a brief, high-pitched tone used ______.A. to urge the caller to speak more quicklyB. to urge the caller to respond quicklyC. as a signal to remind the caller of the time leftD. as a signal to remind the caller that he may leave a message50.Which of the following would be the best title of this passage?A. Directions of Telephone Answering MachinesB. Advantages of Telephone Answering MachinesC. Know-how of Telephone Answering MachinesD. Problems of Telephone Answering MachinesPART TWO (30 POINTS)Ⅳ.WORD FORMATIONSComplete each of the following sentences with the proper form of the word in the brackets.
