After a day of work and play, the body needs to rest. Enough 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 another.
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 that you breathe very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will help you fall asleep!
According to the passage, during REM,______.
选项
A、your eyes move quickly
B、you dream
C、you are restless
D、both A and B
答案
D
解析
根据第三段第二句“…when dreaming occurs,your eyeballs begin to move more quickly…”可知,当人们做梦时,眼球开始快速转动,这个过程叫作REM。因此选项A、B都正确。故选D。
