【題目】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 makes it possible for 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 body relaxes 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, you will dream from time to time. Scientists who study sleep point out that when you are dreaming, 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 suggest breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

【1】The text makes us know that not getting enough sleep might make you _________.

A. suffer form poor health B. enjoy more

C. dream more often D. breathe quickly

【2】 During REM, _______.

A. you move restlessly

B. you start dreaming

C. your mind stops working

D. your eyeballs move quickly

【3】The underlined word “drowsy” in the last paragraph probably means______.

A. lazy B. sleepy C. relaxed D. pleased

【答案】

【1】A

【2】D

【3】B

【解析】

試題分析： 文章主要介紹睡眠的一些知識，睡眠質(zhì)量對身體健康很重要。睡眠有4個階段； 睡不著覺有一些方法如：數(shù)羊、睡前喝一些熱牛奶、深呼吸等。

【1】A 推理判斷題。根據(jù)第一段的句子：Sleep is necessary for good health.推斷，如果缺乏睡眠，就會有健康的問題。故選A。

【2】D細節(jié)理解題：根據(jù)第三段的句子：This stage of sleep is called REM, which stands for rapid eye movement. 可知REM狀態(tài)時，眼球轉(zhuǎn)動的很快。故選D。

【3】B 詞義推測題。本段開頭說有入睡難時怎么辦。 睡前喝些熱牛奶可有助于睡眠，由此可知drowsy是sleepy“困”的意思。故選B。
