1、专业八级分类模拟 191及答案解析(总分:100.10,做题时间:90 分钟)一、READING COMPREHENSIO(总题数:1,分数:100.00)Section A Multiple-Choice Questions In this section there are several passages by fourteen multiple choice questions. For each multiple choice qutestion, there are four suggested answers marked A. B, C and D. Choose the on
2、e that you think is the best answer and mark your answers on ANSWER SHEET TWO. PASSAGE ONE The Great Lyme DebateThere“s a debate raging over Lyme disease, although you“d never know it unless you“ve been paying close attentionbecause on the surface it sounds like the dullest argument imaginable. Last
3、 year, the Infectious Diseases Society of America issued new guidelines saying physicians should treat Lyme with antibiotics for no longer than 30 days. Some docs think that“s wrong. It“s a seemingly straightforward difference of opinion. So why has the debate dissolved into animosity, with one side
4、 suggesting that its opponents have no credibility and the other slinging deeply personal insults on the Web? And why has it now spilled out of medical journals and onto the office of a state attorney general? Clearly, something other than ticks is bugging a lot of doctors. Lyme diseasethe most comm
5、on insect-borne ailment in America, with roughly 20,000 cases diagnosed each year and more undetectedis transmitted mostly by a well-known pest, the deer tick. But the real culprit is something even nastier, a bacterium called Borrelia burgdorferi that lives in the tick“s gut. When Borrelia infiltra
6、tes the human body, it can cause a suite of distinctive symptoms, most notably a flulike feeling and a red rash like a bull“s-eye. Sometimes, though, it causes no symptoms at all, and that“s more dangerous, because the early signs are the only warnings doctors have. If Lyme is left undiagnosed and u
7、ntreated, its consequences can be serious, including arthritis, meningitis, heart problems and inflammation of the brain. “The real secret,“ says Dr. Michael Zimring, director of the Center for Wilderness and Travel Medicine at Mercy Medical Center in Baltimore, “is to be able to recognize the disea
8、se early enough.“ Zimring would know. Several years ago his wife felt fluish and came down with an oval-shaped rash. Zimring wasn“t sure what she had, but “knowing our backyard is loaded with ticks was enough,“ he says. He started his wife right away on one of the classic, effective antibiotics used
9、 to treat Lyme. When her medical tests came back, they proved him right. “I treated her for three weeks,“ he says, “and that was it. No problem.“ Unfortunately, not all Lyme patients recover so easily. And that“s what“s at the heart of the debatesome docs think patients who are treated inadequately
10、can develop a chronic form of the disease, while others deny that it“s possible. Dr. Rafael Stricter, president of the International Lyme and Associated Diseases Society, believes in “chronic Lyme disease,“ and he says that in his clinical experience about 70 percent of patients with it get better i
11、f they“re treated long term with the same drags used to treat early infection. But the doctors who made the new IDSA guidelines on treatment say there“s no such thing as chronic Lyme, because in most patients who complain of it, Borrelia isn“t detectable in the body. Dr. Gary Wormser, who chaired th
12、e IDSA panel, prefers the term “post-Lyme syndrome.“ “Treating that syndrome with high-dose antibiotics for monthsas some physicians did before the new guidelinescan only hurt patients,“ he says. “It can give them gallstones and infections and lead to antibiotic resistance while not curing anything.
13、 The majority of patients treated for “chronic Lyme“ do not have post-Lyme,“ he says, “and in fact never, ever had Lyme disease at all.“ This does not sit well with thousands of patients who believe they do have chronic Lyme and badly want antibiotic treatment for it. “The IDSA is basically saying t
14、o them, “We“re right, you“re wrong, we don“t want to listen to you, just take some antidepressants and go away“,“ says Stricker. The IDSA is a highly respected group of doctors. But it“s facing formidable opposition, not just from Stricker“s group (and angry patients who“ve taken to Internet message
15、 boards) but also from the attorney general“s office in Connecticut, the state with the country“s highest incidence of Lyme disease. A.G. Richard Blumenthal has launched an investigation of the IDSA panel, looking into whether it ignored any research that would support long-term antibiotic treatment
16、 (the guidelines cite more than 400 studies). “Our question basically is whether the guidelines were formulated through a process that was proper, without self-interest or conflicts of interest,“ Blumenthal says, noting that some of the panel members have financial interests in treatments and vaccin
17、es. Blumenthal also worries that the new guidelines might be used by insurance companies looking to avoid paying for Lyme drugs. “The investigation is at an important juncture,“ he says. Meanwhile, Wormser is baffled. “How could the interests of the patient be served by treating with unnecessary and
18、 potentially dangerous therapies?“ he says. “The guidelines represent the best that medical science has to offer.“ The question, then, is whether that“s good enough. PASSAGE TWO The Democrats“ Trade TroublesLast week House speaker Nancy Pelosi and Congressman Charles Rangel showed genuine leadership
19、 by making a deal with the Bush administration to ease the passage of new trade pacts. But they did so from within a party that is going seriously awry on this issue. Too many Democrats, including most of their presidential candidates, simply wish the subject would go away. This is a bad strategy fo
20、r the party and for the country. Bill Clinton“s most important political achievement was to transform the image of the Democratic Party into one that was in favor of growth, markets and trade. Clinton supported and articulated a powerful defense for the North American Free Trade Agreement, the World
21、 Trade Organization and commerce with China, among many such issues. He spoke confidently of the promise and opportunities of a globalized world. When you talk with elected Democrats now, they could not sound more different. Far too many of them are parochial, pessimistic and paranoid about the glob
22、al economy. Globalization and technological change produce real anxieties for many people in the developed world. But the basic facts are incontestable: over the past 20 years, as these forces have accelerated, the United States has benefited enormously. Its companies have dominated the new global e
23、conomic order; its consumers have reaped the lion“s share of the resulting price reductions. America has grown faster than any large industrial economy during these years: over the past two decades, American per capita GDP has roughly doubled. The median income of a family of four rose 23 percent be
24、tween 1985 and 2005. There are serious problems of dislocation and rising inequalityand I“ll return to thesebut that there have been substantial gains is indisputable. U.S. unemployment stands today at a stunningly low 4.4 percent, about half that of many large European economies. In this context it
