Sleep-睡眠
Sleep
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.

此文說(shuō)明了人們?yōu)槭裁匆撸约八郀顟B(tài)中做夢(mèng)的情況。從第三段中可以看出，睡眠中做夢(mèng)是正常情況，而非有些人所認(rèn)為的：做夢(mèng)會(huì)影響休息。文中所用句式、詞匯都非常簡(jiǎn)單，甚至多有重復(fù)，但表達(dá)極為清楚，連貫。

睡眠
很明白，人人都需要睡眠。然而，大多數(shù)人很少思考他們是如何或?yàn)楹嗡叩�。我們知道只要睡好了，就覺(jué)得休息好了。如果睡眠不足，就會(huì)覺(jué)得乏困，易怒。
睡眠好像有兩個(gè)目的：身體休息和情緒或心理休息。我們需要讓軀體和大腦都得到休息。為了保持健康，二者都很重要。每天夜里，我們交替在兩種睡眠之間：積極睡眠和消極睡眠。消極睡眠使我們的身體得到所需的休息，同時(shí)為積極睡眠做準(zhǔn)備。在積極睡眠中，夢(mèng)就出現(xiàn)了。
整個(gè)晚上，人們?cè)谙麡O睡眠和積極睡眠間變換。大腦得以休息，隨后活躍起來(lái)，接著夢(mèng)便開(kāi)始。如此循環(huán)：大腦休息好了，活躍起來(lái)，夢(mèng)又開(kāi)始了。這樣的循環(huán)整個(gè)晚上要反復(fù)好幾次。八小時(shí)的睡眠中，人們平均要做上整整一個(gè)半小時(shí)的夢(mèng)。
