短文：It's clear that everyone needs to sleep.Most people rarely think about how and why they sleep,however.We know that if we sleep well,we feel rested.If we don't sleep enough,we often feel tired and irritable.It seems there are two purposes of sleep:physical rest and emotional and psychological rest.We need to rest our bodies and minds.Both are important in order for us to be healthy.Each night we alternate between two kinds of sleep:active sleep and passive sleep.The passive sleep gives our body the rest that's needed and prepares us for active sleep,in which dreaming occurs.Throughout the night,people alternate between passive and active sleep.The brain rests,then it becomes active,then dreaming occurs.The cycle is repeated:the brain rests,then it becomes active,then dreaming occurs.This cycle is repeated several times throughout the night.During eight hours of sleep,people dream for a total of one and half hours on the average.

楼主 我要说两点：
1 这种阅读这么简单,下次应该自己做
2 但是毕竟要花我几分钟来做,所以麻烦你还是多给个10分,别这么吝啬
1楼你白痴啊 第二个选择是原文：“Each night we alternate between two kinds of sleep:active sleep and passive sleep.”
