单选题 American society is not nap-friendly (喜欢午睡). "In fact", says David Dinges, a sleep specialist in U.S.A. "There's even a prohibition (禁止) against admitting we need sleep. Nobody wants to be caught napping or found asleep at work." Wrong. The way not to fall asleep at work is to take naps when you need them. "We have to totally change our attitude toward napping," says Dr. William Dement of Stanford University, the godfather of sleep research. At present, experts and researchers are becoming more and more concerned about the dangers of sleepiness (睡眠不足): people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Bush is trying to take a half-hour nap every afternoon. About 60 percent of American adults nap when given the opportunity. Actually, sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed (神清气爽的). Clearly, we were born to nap.
