1、专业英语四级（阅读）-试卷148及答案解析 (总分：30.00，做题时间：90分钟)一、READING COMPREHENSIO(总题数：11，分数：30.00)1.PART V READING COMPREHENSION_2.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one th

2、at you think is the best answer._Were always being told by the Department of Health to eat five portions of fruit and vegetables a day. But its not clear where the evidence for this comes from and a large study by the European Prospective Investigation into Cancer and Nutrition(EPIC)two years ago of

3、 the dietary intake of more than 400, 000 people found only a weak link between eating fruit and vegetables and a reduction in overall cancer risk. Theres no evidence it reduces breast or prostate cancer. Even so, how could anyone argue against eating more fruit and vegetables? Well, it depends what

4、 fruit youre eating. A review article in the Canadian Medical Association Journal warns that a chemical in grapefruits can interact fatally with certain medicines. Even apple juice, the staple of many breakfast tables, may reduce our absorption of some drugs. Parents also often think fruit juice is

5、a healthy alternative to soda drinks but juices contain sugar and calories tooas much as a glass of Coke(160 calories)so should be drunk in moderation. Grapefruit has also been linked to an increase in breast cancer. A study in the British Journal of Cancer(BJC)of 500, 000 postmenopausal women found

6、 that eating a quarter of the fruit a day increased the risk by 30%. There is one good reason for not eating grapefruitsthey taste sour. But they are unlikely to increase your risk of breast cancer: further research in the BJC showed no increase of breast cancer in pre- or post-menopausal women who

7、tuck into grapefruits or drink juice. Grapefruit contains a type of chemical called furanocoumarin(also found in Seville oranges and limes but not Valencia or other sweet oranges), which, by inhibiting the enzyme CYP3A4, stops the breakdown of some prescription drugs. So the concentrations of these

8、drugs rise and can have serious side-effects, including kidney damage, heart block(where no electrical impulses pass through the heart and it can stop beating), and deep vein thrombosis(which occurred when an oral contraceptive was taken by a woman who also ate grapefruit three days in a row). Patie

9、nt information leaflets should tell you what foods to avoid with which drugs. If in doubt, ask your doctor. So you dont need to eat less fruit, and may still need to eat more. Another paper from the EPIC study found a 22% reduction in deaths from heart attacks in people who ate eight portions of fru

10、it and vegetables a day compared to those who ate three or fewer. The way the study is designed, however, means that it can only suggest a linkit cant prove one.（分数：6.00）(1).EPIC conducted a research two years ago to_.（分数：2.00）A.prove that people should eat five portions of fruit a dayB.find a way t

11、o reduce the overall cancer riskC.make sure the right amount of fruit eaten every dayD.investigate the relation between eating fruit and reducing cancer risk(2).In parents opinion, fruit juice_.（分数：2.00）A.should not be drunk with drugsB.should be healthier than soda drinksC.may also cause weight gai

12、nD.could be drunk as much as the child like(3).The effect of the chemical in grapefruit on certain medicine might NOT lead to_.（分数：2.00）A.breast cancerB.kidney damageC.heart blockD.deep vein thrombosisIm a 50-something male, the father of two mostly grown girls. Im happy to say that both my parents

13、are still kicking. Im on good terms with my brothers and sisters most of the time. I am blessed with good friends and other relations, and tend to get on well with my co-workers. I am fortunate in so many ways, but feel like I consistently disappoint everyone I know. I cannot, for the life of me, gi

14、ve a genuine compliment. It simply doesnt come naturally. When I try, and I do, in order to maintain all the aforementioned relationships, it feels forced, more a matter of obligation than a gift that might put wind in the sa Is of someone I truly care for. I feel strongly that giving should spring

15、from joy, or at least from a heartfelt desire to see the recipient enlivened by it. When I have nothing to offer in response to a job well done, or I cant cite the intrinsic value of those I love, everyone loses. I feel like Ive warped the emotional and social development of my children, alienated a

16、ny number of perfectly wonderful lovers, and generally kept the world at arms length. I can recall certain compliments given to me through the years. Some of them made all the differences, whether in attaining some goal or simply affording me an elevated sense of self and my rightful place in the wo

17、rld. The value of timely acknowledgment is obvious. After years of psychotherapy and the obsessive self-examination endemic to my generation, I believe I know where this stinginess of spirit comes from. Six kids in total, at a very tender age, there were five younger, cuter kids standing between me

18、and the object of our affection. Mama was driven to distraction, to put it mildly, by the demands placed on her, but it was the 1950s and she set a selfless and hardy example. I had complete sympathy for her difficult situation, even at the time. The fact remains, however, that, as a young child, I

19、needed more than I got. I thirsted for my mothers attention. I needed to know that she valued me as more than her helper, her strong little man. I clearly recall, at the ripe old age of 7, coming to the conclusion that I would never get it. Thats OK, I reckoned, I can get by without it, it being her

20、 love. You can imagine the sibling rivalry in all its permutations. Eventually I took haven in the written word to get away from it. But even before I learned to read, I had realized that giving any sign of approval or encouragement to my brothers and sisters could only serve to increase the gulf be

21、tween me and my mom. Does that make sense? I can rationalize otherwise, of course, and now were all one big happy family, but the damage is done. I want to be gracious and giving, but when I even think to reach into that purse, however, its pretty much empty.（分数：6.00）(1).Which of the following may N

22、OT describe the character of the authors mother?（分数：2.00）A.Expressive.B.Unselfish.C.Realistic.D.Tough.(2).The authors experiences during the childhood indicate all of the following EXCEPT that（分数：2.00）A.the author is the first child of the familyB.his family led a very hard lifeC.his mother gave les

23、s attention to himD.his mother treated him as more than an assistant(3).From the passage, we can draw a conclusion that_.（分数：2.00）A.family has a deep influence on a personB.compliments are very important to a personC.one should treasure the relationship with othersD.when facing tough time, one shoul

24、d never give upIn an effort to sustain commercial and recreational fishing for the next several decades, the United States this year will become the first country to impose catch limits for every species it manages, from Alaskan pollock(till)to Caribbean queen conch(海螺). Although the policy has attr

25、acted scant attention outside the community of those who fish in America and the officials who regulate them, it marks an important shift in a pursuit that has helped define the country since its founding. Catch limits are intended to protect the 528 species in federally managed fisheries. Unlike mo

26、st recent environmental policy debates, which have divided neatly along party lines, this one is about a policy that was forged under President George W. Bush and finalized with President Obamas backing. Its something thats arguably first in the world, said Eric Schwaab, the National Oceanic and Atm

27、ospheric Administrations assistant administrator for fisheries. Its a huge accomplishment for the country. Five years ago, Bush signed a reauthorization of the Magnuson-Stevens Act, which dates to the mid-1970s and governs all fishing in U. S. waters. A bipartisan coalition of lawmakers joined envir

28、onmental groups, some fishing interests and scientists to insert language in the law requiring each fishery to have annual catch limits in place by the end of 2011 to end overfishing. Although NOAA didnt meet the laws Dec. 31 deadlineit has finalized 40 of the 46 fishery management plans that cover

29、all federally managed stocksofficials said they are confident that they will have annual catch limits in place by the time the 2012 fishing year begins for all species.(The timing varies depending on the fish, with some seasons starting May 1 or later.)Some fish, such as mahi-mahi(海豚鱼)and the prize

30、game fish wahoo(刺鲅)in the southeast Atlantic, will have catch limits for the first time. Until recently the nations regional management councils, which write the rules for the 528 fish stocks under the federal governments jurisdiction, regularly flouted scientific advice and authorized more fishing

31、than could be sustained, according to scientists. Joshua Reichert, managing director of the Pew Environment Group, said the laws ban on overfishing forced fishery managers to impose limits that some commercial and recreational fishers had resisted for years. This simple but enormously powerful provi

32、sion had eluded lawmakers for years and is probably the most important conservation statute ever enacted into Americas fisheries law, Reichert said. And unlike many environmental regulations, which are written and enforced by Washington officials, the fishing limits were established by regional coun

33、cils representing a mix of local interests. Because the final decisions were left on the local level, you have a higher assurance of success, said James L. Connaughton, who helped prepare the reauthorization bill while chairing the White House Council on Environmental Quality. If it had been imposed

34、 in Washington, wed still be stuck in 10 years of litigation. But the changes have not come without a fight, and an array of critics are seeking to undo them. Some commercial and recreational operators, along with their congressional allies, argue that regulators lack the scientific data to justify

35、the restrictions. And they suggest that the ambitious goals the law prescribes, including a mandate to rebuild any depleted fish stock within a decade, are arbitrary and rigid.（分数：4.00）(1).Which of the following statements about catch limit policy is CORRECT?（分数：2.00）A.It has attracted the attention

36、 of the whole society.B.It has led to opposite opinions held by lawmakers from different parties.C.It sets limits on the fishery of all federally managed stocks.D.All the catch limits have been finalized by the end of the year 2011.(2).It can be inferred from the passage that_.（分数：2.00）A.U. S. is an

37、 innovator in fishery regulation by setting a universal catch limitB.the Magnuson-Stevens Act is invalid for the time beingC.U. S. has precedents in the process of formulating fishery limitsD.the regional management councils were ignoring the sustainability of fishery beforeI have an uncle who was f

38、or years a Chicago public school teacher. Passionate and articulate about his subject, biology, Arnie cared a great deal about whether the kids learned in his class. But heres the disturbing thing he recalls about his career; In the years that his classes were filled with kids from poor, broken home

39、s who didnt eat or sleep with any regularity, he worried that he wasnt nearly as effective as he wanted to be. He reached some of the kids, sometimes, with some material, but not enough to his liking, no matter what he did or how hard he tried. When he changed schools and suddenly was teaching Kids

40、from middle-class families who valued education, he instantly became a brilliant teacher. His students progressed at a fast clip, and everything he did seemed to work. What some school reformers seem to forget is that the kids circumstances outside school affect their class performance: how much the

41、y eat, how much they sleep, how many words they heard when they were young, how many books were made available to them, the abilities and the disabilities with which they were born, etc. What happens in the classroom is incredibly powerful, but it is not the only thing that matters. This is why it w

42、as so disheartening to hear President Obama wade into a debate about last weeks firing of all of the educators at Central Falls High School in Rhode Island. The firings by the Central Falls school trustees made big headlines, not because reconstituting a school is new, but perhaps because it is the

43、only school in the states poorest and smallest city, and because it was not reported as being the consequence of years of calculated efforts to fix the school(even if it was). Education Secretary Arne Duncan immediately applauded the move, saying the committee members were showing courage and doing

44、the right thing for kids. And today, Obama felt the need to jump in, saying in a speech; So if a school is struggling, we have to work with the principal and the teachers to find a solution. Weve got to give them a chance to make meaningful improvements. But if a school continues to fail its student

45、s year after year after year, if it doesnt show signs of improvement, then theres got to be a sense of accountability. And thats what happened in Rhode Island last week at a chronically troubled school, when just 7 percent of 11th graders passed state math tests7 percent. When a school board wasnt a

46、ble to deliver change by other means, they voted to lay off the faculty and the staff. As my Education Secretary Arne Duncan, says, our kids get only one chance at an education, and we need to get it right. One thing that Obama got right; the school board wasnt able to deliver change, but, unfortuna

47、tely, the school board didnt fire itself. It fired all the administrators and teachers, as if they were the only things responsible for student failure. I wish someone would tell Obama the truth about school restructuring.（分数：4.00）(1).According to the author, why did the firings in the Central Falls

48、 school arouse so much attention?（分数：2.00）A.Because the school has never tried to enhance its situation.B.Because the school was located in a poor area.C.Because Obama attended a debate on the firings.D.Because the school would not be shut down.(2).The author disagreed with Obama that_.（分数：2.00）A.the school failed to make meaningful improvementB.the school had made great effort to fix itselfC.the faculty totally accounted for the failure
