问题     Researchers have found that REM(rapid eye movement)sleep is important to human beings. This type of sleep generally occurs four or five times during one night of sleep lasting five minutes to forty minutes for each occurrence. The deeper a person’ s sleep becomes, the longer the periods of rapid eye movement last.
    There are physical charges in the body to show that a person has changed from NREM(non -rapid eye movement)to REM sleep. Breathing becomes faster, the heart rate increases, and, as the name implies, the eyes begin to move quickly.
    Accompanying these physical changes in the body is a very important characteristic of REM sleep. It is during REM sleep that a person dreams.
Which of the following shows that a person is NOT dreaming in his sleep?
选项 A、His eyes begin to move.
B、His breathing becomes faster.
C、His heart rate increases.
D、His eyes stop moving.
答案D
解析 根据第3段末句“It is duringREM sleep that a person dreams．(在快速眼动睡眠过程中，人才会做梦。)”可以判断出答案应选D。
