填空题The typical picture of a corporate highflier is someone who survives on very little sleep. He or she rises when it is still dark, works late and is still answering emails at two o"clock in the morning. Such people do exist, of course. The late British Prime Minister Margaret Thatcher, for example, was famous for operating on a few hours" sleep. Some entrepreneurs and Wall Street traders seem to follow suit. But if you think you need to do the same thing to get ahead, think again. A growing body of research is finding that, on the contrary, those who get a good night"s sleep are usually more productive at work. That"s because sleep doesn"t just rest the brain, say medical specialists. It allows the brain to perform vital maintenance and restoration tasks. Brains that get too little sleep simply can not perform as well as those that are rested. "There"s no doubt that sleep deprivation affects job performance," says the Detroit Medical Center"s Safwan Badr. "The evidence is compelling that when you do not get enough sleep...you are not as productive." Investors should also take heed: Numerous studies have found that those running on too little sleep tend to make poorer investment decisions and take needless risks as well. Charles Czeisler, a sleep specialist at Brigham you"ll see similar effects if you simply sleep too little each night over time. For the first time, new research has attempted to put some numbers on the link between more Zzzs and more Benjamins. Matthew Gibson, graduate researcher in the economics department of the University of California, San Diego, compared wage data with sleep times recorded in the U.S. Census Bureau"s American Time Use Survey. His conclusion: For those who are sleeping too little, "a onehour increase in longrun average sleep increases wages by 16%, equivalent to more than a year of schooling." Adults need eight hours of sleep on average, experts say. There is some variation between individuals. But when we are tired, we find it much harder to think innovatively and to make creative leaps, say researchers. We find it harder to adapt our thinking to new information or to learn new lessons. Consider: At England"s Loughborough University in 1999, researchers Yvonne Harrison tested the effects of sleep deprivation on a small group of healthy young participants. They were given complex business-situation tasks in the form of a game, as well as some critical reading tasks. Those who went short on sleep were able to keep up with the reading, they found. But when it came to the complex game, "their play collapsed," they Reported. A. agrees that sleep deprivation brings bad effects to investment. B. holds that adults need an average of 8 hours" sleep. C. believes that lack of sleep diminishes your performance. D. thinks it is difficult for people lacking sleep to take up creative work. E. points out the relation between sleep time and American dollars. F. is well known for very little sleep. G. maintains that sleep can rest the brain, and let the brain do other important tasks.

填空题 [A] What route does HIV take after it enters the body to destroy the immune system? [B] How and when did the long-standing belief concerning AIDS and HIV crop up? [C] What is the most effective anti-HIV therapy? [D] How does HIV subvert the immune system? [E] In the absence of a vaccine, how can HIV be stopped? [F] Why does AIDS predispose infected persons to certain types of cancer and infections? In the 20 years since the first cases of AIDS were detected, scientists say they have learned more about this viral disease than any other. Yet Peter Piot, who directs the United Nations AIDS program, and Stefano Vella of Rome, president of the International AIDS Society, and other experts say reviewing unanswered questions could prove useful as a measure of progress for AIDS and other diseases. Among the important broader scientific questions that remain: 41. __________. A long-standing belief is that cancer cells constantly develop and are held in check by a healthy immune system. But AIDS has challenged that belief. People with AIDS are much more prone to certain cancers like non-Hodgkins lymphomas and Kaposi's sarcoms, but not to breast, colon and lung, the most common cancers in the United States. This pattern suggests that an impaired immune system, at least the type that occurs in AIDS, does not allow common cancers to develop. 42. __________. When HIV is transmitted sexually, the virus must cross a tissue barrier to enter the body. How that happens is still unclear. The virus might invade directly or be carried by a series of different kinds of cells. Eventually HIV travels through lymph vessels to lymph nodes and the rest of the lymph system. But what is not known is how the virus proceeds to destroy the body's CD-4 cells that are needed to combat invading infectious agents. 43. __________. Although HIV kills the immune cells sent to kill the virus, there is widespread variation in the rate at which HIV infected people become ill with AIDS. So scientists ask. Can the elements of the immune system responsible for that variability be identified? If so, can they be used to stop progression to AIDS in infected individuals and possibly prevent infection in the first place? 44. __________. In theory, early treatment should offer the best chance of preserving immune function. But the new drugs do not completely eliminate HIV from the body so the medicines, which can have dangerous side effects, will have to be taken for a lifetime and perhaps changed to combat resistance. The new policy is expected to recommend that treatment be deferred until there are signs the immune system is weakening. Is a vaccine possible? There is little question that an effective vaccine is crucial to controlling the epidemic. Yet only one has reached the stage of full testing, and there is wide controversy over the degree of protection it will provide. HIV strains that are transmitted in various areas of the world differ genetically. It is not known whether a vaccine derived from one type of HIV will confer protection against other types. 45. __________. Without more incisive, focused behavioral research, prevention messages alone will not put an end to the global epidemic.
