题目内容
【题目】 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 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 moves 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 say 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!

这是一篇说明文。文章主要介绍了睡眠的一些知识,睡眠的几个阶段,睡眠的重要性,缺乏睡眠的危害。
【1】主旨大意题。根据第一段中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.睡眠对健康是必要的。在这段时间里,身体会从前一天的活动中恢复过来。睡觉时得到的休息能让你的身体为第二天做好准备。可知,主要讲的是有关睡眠的作用。故选A项。
【2】词义猜测题。根据倒数第二段中If you have trouble falling asleep, some people recommend breathing very deeply.如果你很难入睡,有些人建议你深呼吸。喝牛奶其实是为了让自己有睡意,可知,这个单词是“困的,昏昏欲睡的”的意思。故选B项。
【3】细节理解题。根据第三段中when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement.当发生做梦时,你的眼球开始移动得更快(尽管你的眼皮是闭着的)。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。故选C项。
【4】细节理解题。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,不能根据人们的常识来选择选项C“八个钟头左右”,要以文章为依据做出选择。故选D项。
