9、 and treatment. Lung cancer causes more deaths than any other types of cancer. A major cause of the disease is not U U 1 /U /Uknown; there is no good evidence that screening is much helpful, and treatment U U 2 /U /Uin about 90 percent of all cases. At present, therefore, the main strategy must be U

10、 U 3 /U /U. This may not always be true, of course, as for some other types of cancer, research U U 4 /U /Uthe past few decades has produced (or suggested) some importance in prevention, screening or treatment.U U 5 /U /U, however, we consider not what research may one day offer but what todays know

11、ledge could already deliver that is not being delivered, then the most practicable and cost-effective opportunities for U U 6 /U /U. premature death from cancer, especially lung cancer, probably involve neither screening nor improved U U 7 /U /U, but prevention.This conclusion does not depend on the

12、 unrealistic assumption that we can U U 8 /U /Utobacco. It merely assumes that we can reduce cigarette sales appreciably by raising prices or by U U 9 /U /Uon the type of education that already appears to have a U U 10 /U /Ueffect on cigarette assumption by whitecollar workers and that we can substa

13、ntially reduce the amount of tar U U 11 /U /Uper cigarette. The practicability of preventing cancer by such measures applies not only in those countries, U U 12 /U /U, the United States of America, because cigarette smoking has been common for decades, 25 to 30 percent of all cancer deaths now invol

14、ves lung cancer, but also in those where it has become U U 13 /U /Uonly recently. In China, lung cancer U U 14 /U /Uaccounts for only 5 to 10 percent of all cancer deaths. This is because it may take as much as half a century U U 15 /U /Uthe rise in smoking to increase the incidence to lung cancer.

15、Countries where cigarette smoking is only now becoming widespread can expect enormous increase in lung cancer during the 1990s or early in the next century, U U 16 /U /Uprompt effective action is taken against the habit-indeed, such increase is already plainly evident in parts of the U U 17 /U /U.Th

16、ere are four reasons why the prevention of lung cancer is of such overwhelming importance: First, the disease is extremely common, causing more deaths than any other type of cancer now U U 18 /U /U; Secondly, it is generally incurable; Thirdly, effective, practicable measures to reduce its incidence

17、 are already reliably known; and finally, U U 19 /U /Utobacco consumption will also have a substantial U U 20 /U /Uon many other diseases.（分数：20.00）(1).

22、，分数：5.00)Id like to propose that for sixty to ninety minutes every evening right after the early evening news, all television broadcasting in America be prohibited by law.Let us take a serious, reasonable look at what the results might be if such a proposal were accepted. Families might use the time

23、 for a real family hour. Without the distraction of TV, they might sit around together after dinner and actually communicate with one another. It is well known that many of our problems - everything, in fact, from the generation gap to the high divorce rate to some forms of mental illness - are caus

24、ed at least in part by failure to communicate. We do not tell each other what makes us feel disturbed. The result is emotional difficulty of one kind or another. By using the quiet family hour to discuss our problems, we might get to know each other better, and to like each other better.On evenings

25、when such talk is unnecessary, families could rediscover more active pastimes. Freed from TV, forced to find their own activities, they might take a ride together to watch the sunset, or they might take a walk together (remember feet?) and see the neighborhood with fresh, new eyes.With free time and

26、 no TV, children and adults might rediscover reading. There is more entertainment in a good book than in a month of typical TV programming. Educators report that the generation growing up with television can barely write an English sentence, even at the college level. Writing is often learned from r

27、eading. A more literate new generation could be a product of the quiet hour.A different form of reading might also be done, as it was in the past: reading aloud. Few hobbies bring a family closer together than gathering around and listening to mother or father read a good story. The quiet hour could

28、 become the story hour. When the quiet hour ends, the TV networks form our newly discovered activities.At first glance, the idea of an hour without TV seems radical. What will parents do without the electronic baby-sitter? How will we spend the time? But it is not radical at all. It has been only tw

29、enty-five years since television came to control American free time. The people who are thirty-five and older can remember childhood without television, spent partly with radio - which at least involved the listeners imagination - but also with reading, learning, talking, playing games, inventing ne

30、w activities. It wasnt that difficult. Honest. The truth is that we had a ball.（分数：5.00）(1).The failure to talk to each other causes all of the following EXCEPT A. the high divorce rate. B. a real family hour. C. the generation gap. D. some forms of mental illness.（分数：1.00）A.B.C.D.(2).If we turned o

31、ff TV for an hour, which of the following is NOT true? A. We would not have any problems. B. There would be a higher divorce rate. C. Families could take a ride together. D. We would have a new view to neighborhood.（分数：1.00）A.B.C.D.(3).According to the author, A. TV is more entertaining than good bo

32、oks. B. good books are as entertaining as TV. C. good books are not so entertaining as TV. D. good books are more entertaining than TV.（分数：1.00）A.B.C.D.(4).Because young people nowadays dont read much, A. they find TV very entertaining. B. they have a lot of time for other pastimes. C. they have eno

33、ugh time to talk to one another. D. even college students cant write very well.（分数：1.00）A.B.C.D.(5).The idea of an hour without TV is NOT radical because A. TV is very popular among people for only twenty-five years. B. TV is an electronic baby-sitter. C. we might get better shows. D. radio involves

34、 the listener s imagination.（分数：1.00）A.B.C.D.九、BPassage 2/B(总题数：1，分数：5.00)Boston is a tiny place. Even when inner urban suburbs such as Cambridge, Brookline, Somerville, and Chelsea are included, Greater Boston is still unusually small in scale for a major population center. That gives Boston much o

35、f its special flavor. Unfortunately, during times of great prosperity it also creates special challenges.Perhaps the most pressing of these challenges is housing. As the Phoenixs special package on housing shows, the apartment shortage in Greater Boston has reached crisis proportions. Since the mid

36、1990s, rents have gone up by 50 percent or more in some neighborhoods. And even at these grossly inflated prices, apartments are still nearly impossible to come by. Nevertheless, some modest steps can be taken.Its the old not-in-my-backyard syndrome: everyone knows theres a housing shortage, but no

37、one wants to see new housing come into his or her own neighborhood. USuch opposition can be eased by involving local residents in planning for new housing. The lesson is that bottom-up solutions invariably work better than top-down edicts./UBoston University, Boston College, Northeastern University,

38、 and MIT have taken major steps toward building housing for their students on their own campuses. During the 1960s and 70s, student housing spread into neighborhoods such as the Fenway (near Northeastern) and Audubon Circle (near BU). Students kept such neighborhoods alive during those difficult yea

39、rs. But as neighborhoods become able to “thrive on their own“ , universities should be encouraged, wherever possible, to pull back, thus opening up neighborhood housing to long-term residents.In his State of the City address in January, Mayor Tom Menino identified the housing crisis as his number-on

40、e priority, and named a respected legislator, Charlotte Richie, as his housing czar. In a recently published interview, Boston Redevelopment Authority head Tom O Brien spoke of the need to preserve the diversity of Bostons neighborhoods, and identified the citys residential character as one of its s

41、aving graces. Yet the city has been missing in action. At the very least.Menino should make a concerted effort to ease the housing shortage in neighborhoods where the problem is particularly acute. More important, Menino has to realize that he cannot deal with housing as an “in box“ mayor, taking on

42、 an issue here, an issue there as they come up. He should work with officials in surrounding communities and convene a housing summit to consider a wide range of ideas.（分数：5.00）(1).The author thinks that Boston is a tiny place, because _. A. it has a small population B. it covers a small piece of la

43、nd C. it is unusually small in scale for a major population center D. few people know about this city（分数：1.00）A.B.C.D.(2).The author has suggested the following solutions to the housing crisis, EXCEPT _. A. involving grassroots B. back to campus C. improving transportation D. governmental efforts（分数

C. No new houses should be built in my backyard. D. It is the mayors decision and I have no word in it.

45、（分数：1.00）A.B.C.D.(4).The authors attitude towards the government is _. A. hopeful B. disappointed C. sarcastic D. bitter（分数：1.00）A.B.C.D.(5).The authors suggestion to the Mayor is _. A. to sit in his office and listen to reports B. to visit those bothered by lack of housing and listen to their complaints C. to hold a meeting attended by high officials in his government and listen to their advice D. to meet the mayors of nearby cities and listen to their opinions（分数：1.00）A.B.C.D.十、BPassage 3/B(总题数：1，分数：4.00)Discuss
