﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡﹡PART I. READING COMPREHENSION (38%)Directions: Read the passages given below and choose the best answer to the questions attached to each of them.Passage OneQuestions 1-3 are based on the following passage.If you like the idea of staying with a family, living in house might be the answer. Good landladies---those who are superb cooks and launders, are figures as popular in fiction as the bad ones who terrorize their guest and overcharge them at the slightest opportunity. The truth is probably somewhere between the two extremes. If you are lucky, the food will be adequate, some of your laundry may be done for you and you will have a reasonable amount of comfort and companionship .For the less fortune,house rules may restrict the freedom to invite friends to visit, and shared cooking and bathroom facilities can be frustrating and row-provoking if tidy and untidy guest are living under the same roof.The same disadvantages can apply to flat sharing, with the added difficulties that arise from deciding who pays for what, and in what proportion. One person may spend hours on the phone, while another rarely makes calls. If you want privacy with guest, how do you persuade the others to go out; how do you persuade them to leave you in peace, especially if you are student and want to study?Conversely, flat sharing can be very cheap, there will always besomeone to talk to and go out with, and the chores ,in theory, can beshared.1.According to the passage ,landladies are ________ ually strict. B. always mean. C. adequately competent. D. very popular with their guest.2.What is the additional disadvantage of flat sharing ? A. Problems of sharing and paying. B. Differences in living habits. C. Shared cooking and bathroom facilities. D. Restriction to invite friends to visit.3.What is NOT mentioned as a benefit of flat sharing? A. Rent is affordable B. There is companionship. C. Housework.D. There is peace and quiet.Passage TwoQuestions 4-8 are based on the following passage. I am afraid to sleep. I have been afraid to sleep for the last few weeks.I am so tired that, finally, I do sleep, but only for a few minutes. It is not abad dream that wakes me; it is the reality I took with me into sleep . I tryto think of something else. Immediately the woman in the marketplace comes into my mind. I was on my way to dinner last night when I saw her . She was sellingskirts. She moved with the same ease and loveliness I often saw in thewomen of Laos. Her long black hair was as shiny as the black silk of theskirts she was selling. In her hair, she wore three silk ribbons, blue, green,and white. They reminded me of my childhood and how my girlfriendsand I used to spend hours braiding ribbons into our hair. I don’t know the word for “ribbons”, so I put my hand to my own hairand , with three fingers against my head , I looked at her ribbons and said “Beautiful.” She lowered her eyes and said nothing. I wasn’t sure if sheunderstood me (I don’t speak Laotian very well). I looked back down at the skirts. They add designs in them: squaresand triangles and circles of pink and green silk. They were very pretty. Idecided to buy one of those skirts, and I began to bargain with her overthe price. It is the custom to bargain in Asia. In Laos bargaining is done in soft voices and easy moves with the sort of quiet peacefulness. She smiled, more with her eyes than with her lips. She was pleased by the few words I was able to say in her language, although they were mostly numbers, and she saw that I understood something about the soft playfulness of bargaining. We shook our heads in disagreement over the price; then, immediately, we made another offer and then another shake of the head. She was so pleased that unexpectedly, she accepted the last offer I made. But it was too soon. The price was too low. She was being too generous and wouldn’t make enough money. I moved quickly and picked up two more skirts and paid for all three at the price set; that way I was able to pay her three times as much before she had a chance to lower the price for the larger purchase. She smiled openly then, and, for the first time in months, my spirit lifted. I almost felt happy. The feeling stayed with me while she wrapped the skirts in a newspaper and handed them to me. When I left, though, the feeling left, too. It was as though it stayed behind in marketplace. I left tears in my throat. I wanted to cry. I didn’t , of course. I have learned to defend myself against what is hard; without knowing it, I have also learned to defend myself against what is soft and what should be easy. I get up, light a candle and want to look at the skirts. They are still in the newspaper that the woman wrapped them in. I remove the paper, and raise the skirts up to look at them again before I pack them. Something falls to floor. I reach down and feel something cool in my hand. I move close to the candlelight to see what I have. There are five long silk ribbons in my hand, all different colors. The woman in the marketplace! She has given these ribbons to me! There is no defense against a generous spirit, and this time I cry, and very hard, as if I could make up for all the months that I didn’t cry.4. Which of the following in NOT correct?A. The writer was not used to bargaining.B. People in Asia always bargain when buying things.C. Bargaining in Laos was quiet and peaceful.D. The writer was ready to bargain with the woman.5. The writer assumed that the woman accepted the last offer mainly because womanA. thought that the last offer was reasonable.B. thought she could still make much money.C. was glad that the writer knew their way of bargaining.D. was tired of bargaining with the writer any more.6. Why did the writer finally decide to buy three skirts?A. The skirts were cheap and pretty.B. She liked the patterns on the skirts.C. She wanted to do something as compensation.D. She was fed up with further bargaining with the woman.7. When did the writer left the marketplace, she wanted to cry, but did not becauseA. she had learned to stay cool and unfeeling.B. she was afraid of crying in public.C. she had learned to face difficulties bravely.D. she had to show in public that she was strong.8. Why did the writer cry eventually when she looked at the skirts again?A. she suddenly felt very sad.B. she liked the ribbons so much.C. she was overcome by emotion.D. she felt sorry for the woman.Passage ThreeQuestions 9-14 are based on the following passage.The kids are hanging out. I pass small bands of students, in my way to work these morings. They have become a familiar part of the summer landscape.These kids are not old enough for jobs. Nor are they rich enough for camp. They are school children without school. The calendar called the school year ran out on them a few weeks ago. Once supervised by teachers and principals, they now appear to be “self care”.Passing them is like passing through a time zone. For much of our history, after all, Americans arranged the school year around the needs of work and family. In 19th-century cities, schools were open seven or eight hours a day, 11 months a year. In rural America, the year was arranged around the growing season. Now, only 3 percent of families follow the agricultural model, but nearly all schools are scheduled as if our children went home early to milk the cows and took months off to work the crops. Now, three-quarters of the mothers of school-age children work, but the calendar is written as if they were home waiting for the school bus.The six-hour day, the 180-day school year is regarded as something holy. But when parents work an eight-hour day and a 240-day year, it means something different. It means that many kids go home to empty houses. It means that, in the summer, they hang out. “We have a huge mismatch between the school calendar and realities of family life,” says Dr. Ernest Boyer, head of the Carnegie Foundation for the Advancement of Teaching.Dr. Boyer is one of many who believe that a radical revision of the school calendar is inevitable.＂School, whether we like it or not, iseducational. It always has been.”His is not popular idea. School are routinely burdened with the job of solving all our social problems. Can they be asked to meet the needs of our work and family lives?It may be easier to promote a linger school year on its educational merits and, indeed, the educational case is compelling. Despite the complaints and studies about our kids’ lack of learning, the United State still has a shorter school year than any industrial nation. In most of Europe, the school year is 220 days. In Japan, it is 240 days long. While classroom time alone doesn’t produce a well-educated child, learning takes time and more learning takes more time. The long summers of forgetting take a toll.The opposition to a longer school year comes from families that want to and can provide other experiences for their children. It comes from teachers. It comes from tradition. And surely from kids. But the most important part of the conflict has been over the money.9. Which of the following is an opinion of the author’s?A.＂The kids are hanging out.”B.＂They are school children without school.”C.＂These kids are not old enough for jobs.”D. “The calendar called the school year ran out on them a few weeks ago.”10. The current American school calendar was developed in the 19th century according toA. the growing season on nation’s form.B. the labor demands of the industrial age.C. teachers’ demands for more vacation time.D. parents’ demands for other experiences for their kids.11. The author thinks that the current school calendarA. is still valid.B. is out of date.C. can not be revised.D. can not be defended.12. Why was Dr. Boy’s idea unpopular?A. He argues for the role of school in solving social problems.B. He supports the current school calendar.C. He thinks that school year and family life should be considered separately.D. He strongly believes in the educational role of school.13. “The long summers of forgetting take a toll ”in the last paragraph but one means thatA. long summer vacation slows down the progress go learning.B. long summer vacation has been abandoned in Europe.C. long summers result in less learning time.D. long summers are a result of tradition.14. The main purpose of the passage isA. to describe how American children spend their summer.B. to explain the needs of the modern working families.C. to discuss the problems of the current school calendar.D. to persuade parents to stay at home to look after their kids. Passage FourQuestions 15-19 are based on the following passage.Women's minds work differently from men's. At least, that is what most men are convinced of. Psychologists view the subject either as a matter of frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse.There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex inte11ectual processes-the link between the two halves of the brain.The two halves are linked by trunkline of between 200 and 300 million nerves, the Corpus callosum. Scientists have found quite recently that the Corpus callosum in women is always larger and probably richer in nerve fibers than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "What?", and, if this difference exists, are there others? Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we be wrong?Research showed that these two halves of the brain had different functions, and that the Corpus callosum enabled them to work together. For most people, the left half is used for word - handling, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections.But it isn't all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at“language subjects”and boys better at maths and physics. If these differences correspond with the differences in the hemispheric trunkline, there is an unalterable distinction between the sexes.We shan't know for a while, partly because we don't know of any precise relationship between abilities in school subjects and the functioning of the two halves of the brain ,and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.15. Which of the fo11owing statements is CORRECT?A. Biologists are conducting research where psychologists have given up.B. Brain differences point to superiority of one sex over the other.C. Results of scientific research fail to support popular belief.D. The structural difference in the brain between the sexes has long been known.16. According to the passage it is commonly believed that brain differences are caused by ________ factors.A. biologicalB .psychologicalC. physicalD .social17."these differences" in paragraph 5 refer to those inA. skills of men and women.B. school subjects.C. the brain structure of men and women.D. activities carried out by the brain.18. At the end of the passage the author proposes more work onA. the brain structure as a whole.B. the functioning of part of the brain.C. the distinction between the sexes.D. the effects of the corpus callosum.19. What is the main purpose of the passage?A. To outline the research findings on the brain structure.B. To explain the link between sex and brain structure.C. To discuss the various factors that cause brain differences.D. To suggest new areas in brain research.PART II CLOZE (15%)Directions: Choose a proper word from the list to fill in each blank in the following passage.
