1、专业英语四级（阅读）-试卷147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._Considering that industry analysts claim that hospital price calculations are arbitrary, we asked hospitals nationwide a simple question; How do you calculate your sticker prices? Five declined to comment or didnt provide an answer, leaving Murray Askinazi, senior vi

3、ce-president and CFO of Lawrence Hospital Center in Bronxville, New York, to offer this explanation; For an outpatient MRI(核磁共振成像), as an example, his hospital calculates its charge based on such factors as the cost of buying or leasing the machinery, the wear and tear on that machine, staff salarie

4、s, the climate control and electric bill, cleaning costs, local competitive pricing, and other costs related to the hospitals overhead, like malpractice insurance. Surprisingly, medical services can vary wildly from one hospital to the next. The median charge for acute appendicitis admissions at 289

5、 medical centers and hospitals throughout California, for example, ranged from $1, 529 to almost $183, 000, an Archives of Internal Medicine study reported in April. Within San Francisco alone, the range between the lowest and highest charge was nearly $172, 000. But hospital sticker prices matter o

6、nly to a limited extent because they typically get trumped(胜过)by a higher power: the amounts that insurance companies are willing to pay for those services. The figures are determined by a negotiated contract that dictates the rate at which the companies will reimburse the hospital on the patients b

7、ehalf. In addition, the rates paid by Medicare and Medicaid, Askinazi adds, often fail to cover the hospitals cost of providing the service in the first place, which means some of those costs are often shifted to commercially insured patients. Now, all those factors affect the math for one simple ou

8、tpatient test. For an inpatient hospital stay, those computations sprout into an intricate vine in which every service(from radiology to pathology)generates its own charges. The hospital also has facility charges, covering room and board, certain room-use fees(such as the operating room), and nursin

9、g services, all of which get consolidated into the bill sent to you and your insurance company. As technology advances, those charges rise. Palmer had a client from Louisville, Kentucky, who was astonished to receive a charge of $45, 330 for a prostate surgery and an overnight stay(insurance would c

10、over only $4, 845). The billing department told Palmer that the steep price was not only because it was a robotic procedure but also because patients who receive the high-tech surgery shortly after the hospital starts offering it are helping to recoup(偿还)the facilitys equipment costs.（分数：6.00）(1).Wh

11、ich of the following can be inferred from Paragraph Three?（分数：2.00）A.Some of the hospital costs will be covered by commercial insurance companies.B.The insurance companies are willing to pay for all the charges.C.Hospital sticker prices usually get trumped by a high power from the hospital.D.The rat

12、e that insurance companies will pay is determined by themselves.(2).An intricate vine in Paragraph Four refers to_.（分数：2.00）A.the difficulty for an inpatient hospital stayB.the huge amount of hospital chargesC.the problem in calculating hospital chargesD.the complexity of hospital charges(3).The exa

13、mple of Palmers client in the last paragraph indicates that_.（分数：2.00）A.the technology applied in medical services is quite advancedB.the client spent $45, 330 on a prostate surgeryC.the improvement of technology may lead to the rise of hospital chargesD.the surgery was conducted by robots onlyConse

14、rvationists on Tuesday appealed to countries to urgently address new threats to whales, dolphins and other cetaceans(鲸类动物)as climate change opens up previously inaccessible areas of the Arctic and industries move in to new areas. As emotional arguments broke out in the annual International Whaling C

15、ommissions(IWC)conference between pro- and anti-whaling nations over the right of small, aboriginal groups to hunt a few whales each year, WWF appealed to countries to better regulate fishing and stop the oil and gas industries devastating populations. A few thousand whales are killed each year beca

16、use of whaling but 300, 000 whales, dolphins and other cetaceans are killed just in fishing gear. Now the greater threat is from the oil and gas industries. Cetaceans have so far been lucky because the Arctic has been mostly inaccessible but as climate change develops new areas are opening up. These

17、 are some of the most important areas left for whales and cetaceans, said Wendy Eliott, head of the WWF delegation to the meeting in Panama. It is essential these issues are addressed by the IWC. But whaling governments like Norway, Iceland and Japan refuse to acknowledge the conservation committee

18、of the IWC and do not participate. Shell plans to begin drilling operations in the Beaufort and Chukchi seas off Alaska as early as this month, and other oil companies are planning new off-shore drilling platforms in the Russian far east near the feeding area of critically endangered western gray wh

19、ales. There are only an estimated 26 breeding females remaining and the oil-rich zone off Sakhalin Island is the only place where they can teach their calves to feed, said Elliott. This could mark the beginning of a massive oil exploration effort, she said. The IWC, which is regularly torn by disput

20、es, grants five-year permits to communities with a strong tradition of subsistence whaling. This year, several Caribbean countries, including St. Vincent and the Grenadines, as well as the USA, Russia and Denmark are asking approval from the commission for their annual quota of whales to be renewed.

21、 Most whaling opponents do not try to block small-scale aboriginal hunts as they do not threaten larger whale populations. While governments argue that the use of whales and dolphins contribute to national food security, cultural preservation and sustainable livelihoods, some are seen by conservatio

22、nists as ill-disguised commercial whaling. On Monday, pro-whaling countries led by Japan shot down a Latin American-led proposal to create a no-kill zone for whales in the southern Atlantic Ocean. Argentina, Brazil, South Africa and Uruguay put forward a proposal to declare the southern Atlantic a n

23、o-kill zone for whales, a largely symbolic measure as whaling ended there long ago. Thirty-eight countries voted in favor of the measure and 21 voted against, with two abstentions. Under commission rules, proposals need to enjoy a consensus of 75% support for approval.（分数：6.00）(1).According to the p

24、assage, the heated disputes in the annual IWC conference were about_.（分数：2.00）A.the urgency of handling new threats to whalesB.the small native groups right of whale huntingC.the poor management of fishingD.the drilling of oil in Arctic(2).Which of the following is NOT mentioned as the responsibilit

25、ies of IWC?（分数：2.00）A.To regulate whales hunting.B.To make whales adapt to climate change.C.To grant whaling permits.D.To renew annual quota of whales.(3).We can learn from the passage that the proposal about the no-kill zone was_.（分数：2.00）A.deniedB.acceptedC.postponedD.up in the airAlzheimers disea

26、se has no cure. There are, however, five drugsknown and approvedthat can slow down the development of its symptoms. The earlier such drugs are administered, the better. Unfortunately, the disease is usually first noticed when people complain to their doctors of memory problems. That is normally too

27、late for the drugs to do much good. A simple and reliable test for Alzheimers that can be administered to everybody over the age of about 65, before memory-loss sets in, would therefore be useful. Theo Luider, of the Erasmus University Medical Centre in Rotterdam, and his colleagues think they have

28、found onebut it works only in women. They made their discovery, just reported in the Journal of Proteome Research, by tapping into a long-term, continuing study that started in 1995 with 1, 077 non-demented and otherwise healthy people aged between 60 and 90. At the beginning of the project, and sub

29、sequently during the periods 1997-99 and 2002-04, participants were brought in for a battery of neurological(神经学的)and cognitive investigations, physical examinations, brain imaging and blood tests. During the first ten years of the study, 43 of the volunteers developed Alzheimers disease. When Dr. L

30、uider compared blood samples from these people with samples from 43 of their fellow volunteers, matched for sex and age, who had remained Alzheimers-free, he found something startling. Levels of a substance called pregnancy zone protein had been unusually high, even before their symptoms appeared, i

31、n some of those who went on to develop Alzheimers disease. Those some , it turned out, were all women. On average, levels of pregnancy zone protein in those women who went on to develop Alzheimers were almost 60% higher than those of women who did not. In men, levels of the protein were the same for

32、 both. The reason for this curious result seems to be that the brain plaques(斑块)associated with Alzheimers disease are themselves turning out pregnancy zone protein. Certainly, when Dr. Luider applied a chemical stain specific to that protein to the plaques of dead Alzheimers patients he found the p

33、rotein present in them. Confusingly, though, it was there in the plaques of both sexes. Presumably, female cells(and therefore the plaques of female brains)make more of it than male cells do. But that remains to be proved. Whatever the reason, however, this result means that women, at least, may soo

34、n be able to tell whether and when they are at risk of Alzheimersand thus do something about it before they start losing their minds.（分数：4.00）(1).What can we learn from the first paragraph?（分数：2.00）A.No medication can slow down the development of Alzneimers symptoms.B.People who always complain are

35、most likely to have Alzheimers disease.C.Doctors had better tackle Alzheimers disease when people are 65 years old.D.To detect Alzheimers disease before memory loss is crucial.(2).What does Dr. Luiders study tell us about the pregnancy zone protein?（分数：2.00）A.It never increases before the appearance

36、 of Alzheimers symptoms.B.Levels of it remain stable for mens lifetime.C.Women developing Alzheimers usually have lower levels of it.D.The brain plaques connected with Alzheimers produce it.It was not so long ago that parents drove a teenager to college campus, said a tearful goodbye and returned ho

37、me to wait a week or so for a phone call from the dorm. Mom or Dad, in turn, might write lettersyes, with pens. But going to college these days means never having to say goodbye, thanks to near-saturation of cellphones, e-mails, instant messaging, texting, Facebook and Skype. Researchers are looking

38、 at how new technology may be delaying the point at which college-bound students truly become independent from their parents, and how phenomena such as the introduction of unlimited calling plans have changed the nature of parent-child relationships, and not always for the better. Students walking f

39、rom biology class to the gym can easily fill a few minutes with a call to Moms office to whine(抱怨)about a professors lecture. Dad can pass along family news via e-mail. Daily text messaging is not uncommon. Some research suggests that todays young adults are closer to their parents than their predec

40、essors. Professors have figured out that some kids are e-mailing papers home for parents to edit. And Skype and Facebook might be more than just chances to see a face thats missed at home; parents can peer into their little darlings messy dorm room or his messy social life. Experts said the change d

41、ates to 9 - 11, which upped parents anxiety over being out of touch with their children. And the rising cost of college can threaten parents willingness to let children make mistakes as they learn how to be adults. Many of todays college students have had so much of their schedule programmed, so the

42、y may not know what to do with time and solitude, said Barbara Hofer, a Middlebury College psychology professor. Researchers are looking at these changing relationships, formed in the last few years after parents got smartphones and Facebook accounts too and learned how to use them. Theres a tremend

43、ous diversity in how kids handle this. Some maintain old rules. But for many, many young people, they grow up essentially with the idea that they dont have to separate from their parents, said Turklea, professor at the Massachusetts Institute of Technology whose specialty is technology and relations

44、hip. Its about having an adolescence that doesnt include the kind of separation that we used to consider part of adolescence, she added. Hofer and colleagues surveyed students at Middlebury in Vermont and at the University of Michigan, two schools different in many ways. But at both, parents and stu

45、dents were in contact frequently, an average of more than 13 times a week. The parents of todays college students were advised to get involved in the childrens lives to communicate, communicate, and communicate. All that talk can signal a close, useful relationship, but it also can leave kids lackin

46、g what they need to fend for themselves.（分数：4.00）(1).It can be inferred from the passage that_.（分数：2.00）A.parents feel greatly relieved after sending their children to collegeB.parents today have quick access to their childrens campus lifeC.todays young adults are well-prepared for dealing with lone

47、linessD.there is a lack of communication between young adults and their parents(2).According to the passage, the change of parent-children relationships has little to do with_.（分数：2.00）A.childrens strong desire to be independentB.easy access and low cost of communicationC.the rising cost of higher educationD.parents anxiety derived from 9-113.SECTION BIn this section there are five short answer questions based on the passages in Section A.
