单选题 {{B}}Text 2{{/B}}

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.

单选题 It is true in American society that ______.

【正确答案】 A

【答案解析】[解析] 是非判断题：参考文章最后一段“About 60 percent of American adults nap when given the opportunity”，我们可以推断[B]与之明显不符。另外，[C]、[D]与常识不符合，并且也没有在文章中提到。而[A]可以从第一段找到依据。故正确答案是[A]。

单选题 What can we infer from the passage?

【正确答案】 C

【答案解析】[解析] 推理题。[A]项内容文中没有提到，而且不符合常理；[B]项与课文内容不符合；[D]在课文最后一段明确交代，所以不是推理。唯有[C]项与文中进到的“We have to totally change our attitude toward napping”，意思相吻合，而且是作出的合理推理。故答案是[C]。

单选题 The purpose of this article is to

【正确答案】 D

【答案解析】[解析] 主旨题。本题要求辨别此文的写作意图。通读课文，第一段指出：美国是一个不喜欢午睡的社会。第二段指出这种说法是错误的，“wrong” 一词表明作者持批判态度。第三段指出了睡眠少所引发的危害：各种工业和交通事故。而最后一段，作者更是明确态度，说明午睡的必要和好处。所以该文章的目的是[D]项“使读者相信午睡的必要性”。
