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.
The subject of this passage is______.
选项
A、why people sleep
B、the human need for REM sleep
C、the characteristic of REM sleep
D、physical changes in the human body
答案
D
解析
了解文章主要论题的关键是找到全文的主题句。根据第2段首句和第3段首句可知本文主要讲述了睡眠中人体的许多生理功能会发生明显的变化,如呼吸急促、心率加快、血压升高,最奇怪的是眼球不停地左右摆动。故选项D为正确答案。
