If national health insurance would not cure the problems of the American healthcare system, what, then, is responsible for them？ Suspicion falls heavily on hospitals, which make up the largest component of the system. In 1988 hospitals accounted for 39% of all health expenditures-more than doctor, nursing homes, drugs, and home health care combined.

Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction. According to the passage, which of the following is NOT true？ A．Eating less than usual might make us live longer. B．If we go on a diet when old, we may keep healthy.

We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively. The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors. The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively. What is the speaker's main topic？ A．Effects of using mobile phones on healthy human cells. B．Risks of developing cancer involved in the use of mobile phones. C．Damage to healthy cells caused by the use of mobile phones. D．The potential health hazards of mobile phones on humans.

Gro Harlem Brundtland made her comments to the World Health Assembly in Geneva, Switzerland recently. She described a number of health programs expected in the coming years. However, Doctor Brundtland said the WHO' s 191 member countries must support the programs and put them into action. With this support, she said the WHO could reduce the number of deaths caused by malaria, AIDS, tuberculosis and other infectious diseases. She also said the death rate for pregnant women and babies could be reduced. Doctor Brundtland told W-H-O members that good health is linked to economic and social development. For example, she described how smoking tobacco threatens to reduce the resources of all countries, especially developing countries. The World Health Organization estimates that four million people die each year from diseases linked to smoking. The organization expects that number to rise to ten- million a year in the next thirty years. Most of these deaths are expected in developing countries. Which of the following infectious diseases is not mentioned in the report？ A．Malaria. B．Enteritis. C．AIDS. D．Tuberculosis.

These recent initiatives owe a great deal to one artist, Peter Senior, who set up his studio at a Manchester hospital in north-eastern England. The quality of the environment may reduce the need for expensive drugs when a patient is recovering form. an illness. A study has shown that patients who had a view on to a garden needed half the number of strong pain killers compared with patients who had no view at all or only a brick wall to look at during the early 1970s. he felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience. A typical hospital waiting room might have as many as 5 000 visitors each week. What better place to hold regular exhibitions of art？ Senior held the first exhibition of his own paintings in the out-patients' waiting area of the Manchester royal Infirmary in 1975. Believed to be Britain's first hospital-artist, Senior was so much in demand that he was soon joined by a team of six young art school graduates. The effect is striking. Instead of the familiar long, barren corridors and dull waiting rooms, the visitors experience a full view of fresh colours, playful images and restful courtyards. Compared with the total number of Britain's National Health Service hospitals, the hospitals which have art collections is only ______. A．4% B．40% C．25% D．50%.

The shift, little noticed outside the medical establishment but already controversial inside it, suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent. In practical terms, the new guidelines being developed could result in doctors choosing one drug over another for cost reasons or even deciding that a particular treatment-at the end of life, for example-is too expensive. In the extreme, some critics have said that making treatment decisions based on cost is a form. of rationing. Traditionally, guidelines have heavily influenced the practice of medicine, and the latest ones are expected to make doctors more conscious of the economic consequences of their decisions, even though there’s no obligation to follow them. Medical society guidelines are also used by insurance companies to help determine reimbursement(报销)policies. Some doctors see a potential conflict in trying to be both providers of patient care and financial overseers. "There should be forces in society who should be concerned about the budget, but they shouldn’t be functioning simultaneously as doctors," said Dr. Martin Samuels at a Boston hospital. He said doctors risked losing the trust of patients if they told patients, "I’m not going to do what I think is best for you because I think it’s bad for the healthcare budget in Massachusetts." Doctors can face some grim trade-offs. Studies have shown, for example, that two drugs are about equally effective in treating macular degeneration, an eye disease. But one costs $50 a dose and the other close to $2,000. Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug. Avastin, instead of the costlier one, Lucentis. But the Food and Drug Administration has not approved Avastin for use in the eye, and using it rather than the alternative, Lucentis, might carry an additional, although slight, safety risk. Should doctors consider Medicare’s budget in deciding what to use？ "I think ethically(在道德层面上)we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole," said Dr. Donald Jensen. Still, some analysts say that there’s a role for doctors to play in cost analysis because not many others are doing so. "In some ways," said Dr. Daniel Sulmasy, "it represents a failure of wider society to take up the issue." 57.What do some most influential medical groups recommend doctors do？ A.Reflect on the responsibilities they are supposed to take.
