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.
According to the passage, how often does REM sleep occur during one night?
选项
A、Once.
B、Twice.
C、Four of five times.
D、Forty times.
答案
C
解析
本题是细节判断题,根据第1段的第2句“This type of sleep generally occursfour or five times during one night of sleeping…”,故答案应选C。
