Reading Comprehension (2 points each, 2×20=40 points)Passage 1There is no doubt that adults, and even highly educated adults, vary greatly in the speed and efficiency of their reading. Some proceed very slowly throughout; others dash along too quickly and then have to regress. Poor readers in particular may lack the ability to vary their manner of reading according to the type of reading matter and to their intentions in reading it. A good reader can move at great speed through the text of a novel or similar light reading matter. He may be able to skim a page, picking up a word or two here and there, and gain a general idea of what the text is about without really reading it. In reading more difficult material, with the intention of taking in the whole of it, he will proceed more slowly, but even then he will vary his pace, concentrating on the key words and passages, perhaps re-reading them several times and pass more quickly over the remainder. A less efficient reader tends to maintain the same speed whatever the material he reads. Consequently, even light reading matter gives him little pleasure because he reads so slowly. Butthis pace may be too fast for really difficult material which requires special concentration at difficult points.A type of reading which necessitates careful attention to detail is proofreading, in which the reader, in order to detect misprints in a sample print, has to notice not so much the meaning of what he reads as the exact shape and order of letters and words in the text. This is extremely difficult for most people, since they are accustomed to overlooking such details. In fact, considerable practice is required to practise this task efficiently and it can be done only by reading very slowly, and by paying comparatively little attention to the general meaning of the text.1.

Almost every type of physical land feature, sort of arctic ice fields and tropical jungles can be found within its borders. Sharply contrasting types of land often lie very close to one another.People living in Bakersfield, for instance, can visit the Pacific Ocean and the coastal plain, the fertile San Joaquin V alley, the arid Mojave Desert, and the high Sierra Nevada, all within a radius of about 100 miles. In other areas it is possible to go snow skiing in the morning and surfing in the evening of the same day, without having to travel long distance.Contrast abounds in California. The highest point in the United States (outside Alaska ) is in California, and so is the lowest point (including Alaska). Mount Whitney, 14,494 feet above sealevel, is separated from Death V alley, 282 feet below sea level, by a distance of only 100 miles. The two areas have a difference in altitude of almost three miles.California has deep, clear mountain lakes like Lake Tahoe, the deepest in the country, but it also has shallow, salty desert lakes. It has Lake Tulainyo, 12,020 feet above sea level, and the lowest lake in the country, the Salton Sea, 236 feet below sea level. Some of its lakes, like Owens Lake in Death V alley, are not lakes at all: they are dried up lake beds. In addition to mountains, lakes, valleys, deserts, and plateaus, California has its Pacific coastline, stretching longer than the coastlines of Oregon and Washington combined.6. Which of the following is the lowest point in the United States?A. Lake Tulainyo.B. Mojave desert.C. Death V alley.D. The Salton Sea.7. Where is the highest point in the United States located?A. Lake Tahoe.B. Sierra Nevada.C. Mount Whitney.D. Alaska.8. How far away is Death V alley from Mount Whitney?A. About 3 miles.B. Only 100 miles.C. 282 feet.D. 14,494 feet.9. Which of the following is NOT mentioned in the passage as being within a radius of about 100 miles of Bakersfield?A. The Pacific Ocean.B. San Joaquin V alley.C. Mojave Desert.D. Oregon and Washington.10. Which statement best demonstrates that California is a land of variety and contrastA. The highest lake in California is Lake Tulainyo.B. It is possible to go surfing and snow skiing in some parts of California without having to travel long distance.C. Sierra Nevada, San Joaquin V alley, Mojave Desert and the Pacific Ocean all lie within a radius of about 100 miles.D. Owens Lake, in Death V alley, is not really a lake at all.Passage 3Upon reaching an appropriate age (usually between 18 and 21 years), children are encouraged, but not forced, to ―leave the nest‖ and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children, nor do children usually ask permission of their parents to get married, Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses (配偶) through other friends, at jobs, and in organizations and religious institutions. Although children choose their own spouses, they still hope their parents will approve of their choices.In many families, parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father’s business because of a fear that he will lose his autonomy in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family. Coexisting with such love in the American family are cultural values of self – reliance and independence.11. The writer discusses the marriage of young adults in order to show which of the following?A) They enjoy the freedom of choosing their spouses.B) They want to win the permission of their parents.C) They have a strong desire to become independent.D) They want to challenge the authority of their parents.12. Most young adults in the U.S. get married for the sake of ____.A) love B) financial concern C) their parents D) family background13. Based on the passage, it can be assumed that ______.A) American young adults are likely to follow the suit of their parentsB) most American people never make major decisions for their childrenC) American young adults possess cultural values of independenceD) once a young person steps into his twenties, he will leave his home permanently14. A son is unwilling to work in his father’s business mai nly because _____.A) he wishes to make full use of what he has learnt in schoolB) he wants to prove his independenceC) he wishes to do the opposite of what his parents approve ofD) he wants to show his love for his parents15. The subject matter of this selection is _____.A) family values B) marriage arrangementsC) the pursuit of a career D) decision makingPassage 4Cancer is feared by everyone. And this fear is reaching epidemic(流行性) proportions. Not the disease itself — there is no such thing as a cancer epidemic. Except for lung cancer, mostly caused by cigarette smoking ,the incidence rates are leveling off, and in the case of some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety, The earth itself is coming to seem like a huge carcinogen(致癌物). The ordinary, more or less scientific statement that something between 80 and 90 percent of all cancers are dun to things in the environment is taken to mean that none of u s will be safe until the whole environment is ―cleaned up.‖ This is not at all the meaning.The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high proportion of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data indicate there may be special and specific environmental influences, largely based on personal life-style, that determine the incidence of various forms of cancer in different communities —but that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.16.Which of the following is closest to meaning to the phrase ―leveling off‖?A)Became very popular B)Reached its lowest level in popularityC)Stopped being popular D)Stopped increasing its popularity17.According to the passage, the incidence of cancer is generally believed _____.A)to be based on inactive life style B)to be due to anxietyC)to result from environmental influences D)to be caused by heavy smoking18.It can be inferred from the passage that the writer’s opinion about the relationship between cancer and environment is_____.A)positive B)negative C)neutral D)approving19.According to the passage, the writer seems to feel that_____.A)cancer risk is on the riseB)the whole earth resembles a huge carcinogenC)the risk of catching cancer is not so great as most people conceiveD)cancer can be cured sooner or later20.Which of the following would be the best TITLE for the passage?A)Cancer and EnvironmentB)The Fear Caused by CancersC)Data on Cancer IncidenceD)Cancer and its InvestigationⅣ.
