Question

【题目】(A) No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects (产生明显的反应) after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations (幻觉).

There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. (B)如果你感觉好的话, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.

Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns (睡眠模式) also tend (倾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting worse, and often make it a rule to sleep during the daytime.

【解析】

睡眠对我们是非常重要的，睡眠不足会带来很多的问题，文章就不同的年龄阶段的睡眠时间和模式进行说明．

【1】翻译题。根据题干No one knows why we sleep, but it’s certain that we need to.可知，先逐词翻译，不定代词No one是没有人；疑问词why是为什么；代词we是我们；sleep是睡觉；连词but表转折，但是；it’s certain that中的it是形式主语，真正的主语是that引导的从句，所以是我们需要睡觉是毫无疑问的，再调整语序看，故答案是没有人知道我们为什么睡觉，但我们需要睡觉是毫无疑问的。

【2】翻译题。根据汉译“如果你感觉好的话”可知，这是以if引导的条件状语从句，感觉用feel，故答案是If you feel all right,

【3】细节理解题。根据文章grown-ups sleep about 7 and a half hours each night和Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage.可知，刚出生的孩子们睡14-18个小时，青少年睡的和成人是一样的，大约7个半小时，故答案是Children sleep about 14 to 18 hours soon after birth and teenagers sleep about 7 and a half hours.

【4】细节理解题。根据题干可知，They are sleepy at work.是说他们工作时很困，找出同义句，故答案是They fall asleep during the working hours

【5】主旨大意题。根据文章可知，本文的主题句是No one knows why we sleep, but it’s certain that we need to.其中but后面的部分是中心，我们需要睡觉，换句话说睡眠对我们来说是重要的，故答案是C
