Question

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

　　There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

　　Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

　　If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

【解析】

试题分析：文章大意：本文讲了睡眠的重要性及与其有关的几个方面的问题，充足的睡眠能让你恢复体力，让第二天的你精力充沛。

1.A主旨大意题。根据第一段并浏览全文不难看出本文的题目跟Sleep有关，而且sleep在每段都多次涉及，由此也可以得出本文的主旨就是sleep。所以答案很容易就选择出A来。

2.D 猜测词义。 根据文章句子Other people believe that drinking warm milk will help make you drowsy. 不难翻译出“有人认为喝牛奶会帮助人们drowsy”根据常识也知道牛奶可以催眠，但是并不能直接让人睡着，所以B、asleep是指“睡着的”，D、a little sleepy 指“有点睡意”，这样对比可以确定答案应该用D。

3.B 推理题。文章开始就提到Sleep is necessary for good health.言外之意就是说，没有充足的睡眠对身体不好，因此选B。其它选项文章都没有提到。

4.D 细节题。根据文章第三段when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement.可知，在所谓的REM阶段，人是处于梦境中，而且眼球会快速转动。所以综合两点选D。

5.D 细节题。纵观全文文章并没有提到各个年龄阶段的人们的最佳睡眠时间，所以答案为D。不能根据人们的常识来选择C、八个钟头左右。要以文章为依据做出选择。
