Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.Doctors have long known that__________.

Americans have learnt more about drinks than they were 20 years ago. Now, encouraged by recent studies suggesting that it can cut the risk of cancer and heart disease and slow the aging process, tea is enjoyed by more and more people. Enough fashionable tea houses are appearing to make even longtime coffee drinkers consider changing drinks.
Tea is found in more places than ever. The Tea Association of the United States reports that from 1990 to 1999, yearly sales of the drink grew to $4.6 billion from $1.8 billion. “Green tea is seen by people as a ‘functional food’” — bringing health beyond food itself, says Vierhile.
Recently published studies point out that only teas that come from the leaves of the plant Camellia sinensis contain health benefits. Other teas may taste good, yet they do little more than warm up the drinker. But for Camellia sinensis, the evidence is powerful. In a 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the danger of heart disease by as much as 44 percent compared with non-tea drinkers, and other studies have suggested that the antioxidants (抗氧化剂) in these so-called real teas can also prevent cancer.
One such antioxidant in green tea is ECGC, a chemical 20 times as powerful as vitamin E and 200 times as powerful as vitamin C. “When people ask me for something good and cheap they can do to reduce their cancer risk, I tell them to drink real tea,” says Mitchell Gaynor, director of medical oncology (肿瘤学) at New York City’s Strang-Cornell Cancer Prevention Center.
