考研英语核心词汇速成胜经Unit 2


考研英语核心词汇速成胜经 Unit 2 一,真题文章

Sleep is divided into periods of so-called REM sleep, characterized by rapid eye movements and dreaming, and longer periods of non-REM sleep. Neither kind of sleep is at all well-understood , but REM sleep is assumed to serve some restorative function of the brain. The purpose of non-REM sleep is even more mysterious .The new experiments, such as these described for the first time at a recent meeting of the Society for Sleep Research in Minneapolis, suggest fascinating explanations for the purpose of non-REM sleep . For example, it has long been known that total sleep deprivation is 100 percent fatal to rats, yet , upon examination of the dead bodies , the animals look completely normal . A researcher has now cast light on the mystery of why the animals die. The rats develop bacterial infections of the blood , as if their immune systems--the self-protecting mechanism against disease--had crashed crashed.

二,译文
睡眠通常被分为所谓的 REM 睡眠阶段(REM=rapid eye movement 眼睛快速运 动)和较长非 REM 睡眠阶段,前者特点为眼球快速转动并做梦.我们对两种形式 的睡眠了解都不多,但是人们认为 REM 睡眠对大脑起某种康复功能的作用.非 REM 睡眠的作用更加神秘.最近睡眠研究协会在明尼阿波利斯举行的会议上,专 家们首次描述的一些新实验,对非 REM 睡眠的作用的阐释令人兴奋. 例如,人们早已了解到,完全剥夺其睡眠对老鼠具有 100%的致命性,然而, 在检查老鼠尸体时,这些动物看上去完全正常.一研究人员已阐明这些动物死亡 原因的奥秘.老鼠患血液细菌感染,似乎他们的免疫系统(抵抗疾病的自我保护 机制)已崩溃.
