Are undergraduate grades important? Everyone knows that high marks earned at different schools or under different instructors can indicate very different levels of achievement. One professor may be a hard grader, while another is very generous or one who takes the whole business as a bit of joke. Some schools have nigh standards, whereas others are groups of intellectual people. And at all universities, there is a constant tendency towards grade inflation （the granting of ever more high marks）. That is fought vigorously at some institutions and allowed to go unchecked for long periods at others.Another point raised against grades is how poorly they predict how much graduates will be earning 15 or 20 years after getting their degrees. As many studies have shown, there is only a very poor correlation between undergraduate’s grades and subsequent wealth. People who get good marks tend to go into the professions, not all of which are highly remunerative（有利的）.The correlation between undergraduate grades and success in business, the most common road to wealth, is virtually nothing. Many mediocre（平庸）students become successful businessman, while some brilliant and capable graduates （creative youngsters, not students with special skills in passing exams） take up relatively low-paying but interesting or satisfying careers. The general population, examining this question through a statistical lens, sees one thing very clearly that good grades don’t translate in any direct way into big bucks, and for better or for worse, the gauge（标尺） of “success” for countless Americans is the acquisition of wealth.The result is a certain modesty about good grades in America among those who get them. A student’s parents may brag about his marks, but seldom will the student himself risk being branded a “grade-grubber” by drawing too much attention to his academic success. High marks are not something to be advertised to the world except on resumes, and anybody who boasts about them is likely to be viewed with contempt, not least by intelligent people.1.Which of the following is true about undergraduate grades?2.According to the passage, what is the relationship between grades and business performance?3.Which of the following best describes the American attitude towards good grades?4.The phrase “grade-grubber”, underlined in paragraph 3 probably means （ ）.5.What might be the best title for this passage?

The multibillion-dollar international pharmaceutical industry has been accused of manipulating the results of drug trials for financial gain and withholding information that could expose patients to possible harm.The stranglehold the industry has on research is causing increasing alarm in medical circles as evidence emerges of biased results, under-reporting and selective publication driven by a market worth more than 10 billion pounds in Britain alone.The industry has sponsored the trials of new drugs which have held out great promise for patients with cancer, heart disease, mental health problems and other illnesses.But the tests on the same drugs in independent trials paid for by non-profit organizations — governments, medical institutions or charities — have yielded very different results.The drugs for abnormal heart rhythm introduced in the late 1970s were killing more Americans every year by 1990 than the Vietnam War.Yet early evidence suggesting the drugs were lethal, which might have saved thousands of lives, went unpublished.Expensive cancer drugs introduced in the past 10 years and claiming to offer major benefits have increasingly been questioned.Evidence published in the Journal of the American Medical Association showed that 38 per cent of independent studies of the drugs reached unfavorable conclusions about them, compared with 5 per cent of the studies paid for by the pharmaceutical industry.In the latest case, the researchers commissioned by the National Institute for Clinical Excellence to develop guidelines for the prescribing of anti-depressant drugs to children say they were refused access to the unpublished trials of the drugs held by the pharmaceutical companies.Published evidence suggested that the anti-depressant drugs were safe and effective for children.But when they obtained the unpublished evidence by contacting individual researchers who had worked on the trials and other sources, a different picture emerged — one of an increase in suicidal thoughts and attempted suicide. Only one of the drugs, Prozac, emerged as safe.Anti-depressant drugs, though not recommended for children, were widely prescribed in Britain until last year, when the Medicines and Healthcare Products Regulatory Agency issued a warning to doctors, prohibiting their use.This followed the safety concerns raised by campaigners and taken up in two BBC TV Panorama broadcasts which brought the biggest response in the program’s history. Writing in the Lancet medical magazine, the researchers say: “On the basis of published evidence alone, we could have considered at least tentatively recommending use of these drugs for children and young people with depression. ’’1.The international pharmaceutical industry has been criticized for（ ） .2.The phrase “independent trials”(in Paragraph 4) in this context means “conducting the trials without （ ） .3.What was true about the drugs for abnormal heart rhythm?4.According to the passage, the unfavorable conclusions about drugs were kept a secret from（ ） .5.The information unpublished about the anti-depressant drugs showed that（ ）.6.It can be inferred that, 2 years ago, to the doctors prescribing anti-depressant drugs, the published evidence about the drugs would seem to be very （ ） .

There have been five extinction waves in the planet’s history — including the Permian extinction 250 million years ago, （1） an estimated 70% of all land animals and 96% of all marine creatures vanished.

No doll outshines Barbie’s celebrity. If all the Barbies and her family members — Skipper, Francie and the rest —sold since 1959 were placed head to toe, they would circle the Earth more than seven times. And sales boomed in 2009, when the fashion doll celebrated her 50th birthday on March 9th.Barbie starred at an array of global events honouring her milestone, including a glamorous affair at New York’s Fashion Week in February. On her birthday, Mattel, the company that makes her, launched a souvenir doll honouring the original Barbie in her black-and-white striped swimsuit and perfect ponytail. It was available for purchase only that one day. Another Golden Anniversary doll targets collectors. Barbie fans planned hundreds of events, including the National Barbie Doll Collectors Convention in Washington, D. C. , which was sold out.When Ruth Handler created Barbie in 1959, a post-war culture and economy thrived but girls still played with baby dolls. These toys limited the imagination ； so Handler introduced Barbie the Teen-Age Fashion Model, named after her daughter, Barbara. Jackie Kennedy soon walked onto the world stage and Barbie already had a wardrobe fit for a first lady. Barbie bestowed on girls the opportunity to dream beyond suburbia, even if Ken ( Barbie’s fictional boyfriend) at times tagged along.Barbie entranced Europe in 1961 and now sells in 150 countries. Every second three Barbies are sold around the world. Her careers are myriad — model, astronaut, Olympic swimmer, palaeontologist and rock star, along with 100 others, including president. Like any political candidate, controversy hit Barbie in 1992 when Teen Talk Barbie said “Math class is tough” and girls’ education became a national issue. She has been banned (in Saudi Arabia) , tortured (by pre- teen girls, according to researchers at the University of Bath’s School of Management) and fattened (in 1997).Feminists continue to batter Barbie, claiming that her beauty and curves treat women as objects. But others see her as a pioneer trendsetter, crashing the glass ceiling long before Hillary Clinton cracked it.High-tech entertainment now attracts girls and Barbie also faces fierce competition from various copycats including the more fashionable, but less charming, Bratz dolls. The Bratz suffered a setback in 2008. Mattel sued MGA Entertainment, Bratz’s producer, for copyright infringement.

“Physician specialty, in addition to being a measure of formal training in the field, is also a proxy for clinical experience,” he says. “If s very difficult to separate out the overlapping concepts: one, that practice makes perfect; two, the effect of the educational and time investments in a clinical problem the physician is simply interested in; and three, the issue of formal training.”Differences between specialist care and generalist care, however, pale in comparison with the finding that both specialists and generalists often fail to put the latest knowledge into practice, contend both Donohoe and Clancy. A report by the U. S. General Accounting Office documented that heart attack survivors who saw cardiologists regularly were more likely to take cholesterol-lowering drugs and beta blockers—which reduce heart rate and blood pressure—than those who received care from a generalist. Even so, these life-prolonging drugs were not prescribed to many patients who appeared to be eligible for them, implying that both generalists and specialists could do better.“Maybe we are focusing too much energy on the differences between generalist and specialist care,” says Donohoe. Perhaps, he adds, “we should focus more intently on improving the quality of communication and cooperation between generalists and specialists and on developing and promoting practice guidelines that might have a much bigger effect on the overall health of Americans.”1.Which of the following questions can most probably come out of the two questions raised in the passage?2.The answers to the two questions suggest that （ ）.3.According to the passage, the better treatment of stroke and heart disease on the part of specialists （ ）.4.Both specialists and generalists, Donohoe and Clancy contend, could do a better job of （ ）.5.Donohoe is trying to shift our attention to （ ）.
'>It seems intuitive that going to a specialist physician will result in more thorough and up-to-date care for whatever ails you. In fact, many studies support this idea—but health-care researchers caution that they may not tell the whole story.The first question is whose patients are sicker? Specialists tend to treat more complicated forms of disease, but generalist—family physicians and general practitioners—are more likely to treat patients with several coexisting diseases.A second question is what counts as the most valuable treatment? Specialists are more familiar with standards of care for the diseases they treat regularly, says Harlan M. Krumholz of Yale University. On the other hand, a generalist may do a better job of coordinating a patient's care and keeping an eye on a person's overall health, says Martin T. Donohoe of the Oregon Health Sciences University in Portland.To further complicate comparisons, many generalists will consult with specialists on complicated cases ,but medical records do not always show that, says Carolyn Clancy of the Agency for Health Care Policy and Research in Rockville, Md.That said, stroke patients treated by neurologists are more likely to survive than stroke pat
