特殊實驗室四級英語作文

　　a unique laboratory at the university of chicago is busy only at night. it is a dream laboratory where researchers are at work studying dreamers. their findings have showed that everyone dreams from three to seven times at night although in ordinary life a person may remember none or only one of his dreams.

　　while the subjects――usually students――sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of dream. surprisingly, all subjects sleep soundly.

　　observers report that a person usually figets before a dream. once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. as soon as the machines show that the dream is over, a buzzer wakes the sleeper. he sits up, records his dream and goes back to sleep, perhaps o dream some more.

　　researchers have found that if the dreamer is wakened immediately after the dream, he can usually bring back to his mind the entire dream. if he is allowed to sleep even five more minutes, his memory of the dream will have gone.

　　“特殊實驗室”英語作文譯文：

　　芝加哥大學(xué)的一間特殊實驗室只在夜間忙碌。這是一間析夢實驗室。研究人員在這里致力于對做夢人的`研究。他們的研究結(jié)果表明每個人每晚做二到七次夢。不過在平常生活中，一個人也許連一個夢也記不住，或者只能記住一個夢。

　　當(dāng)受試者――一般是學(xué)生――睡著的時候，特殊機器就將記錄下來他們的腦電波和眼睛運動以及標(biāo)示他們夢已結(jié)束身體運動，令人驚奇的是，所有的受試者都睡得非常沉。

　　觀察者報告說，一個人在做夢之前常有不安表現(xiàn)。一旦開始做夢，他的身體便松弛下來，而眼睛運動則活躍起來，就像演出的大幕升起之后。一旦機器顯示一個夢做完了，蜂鳴聲就叫醒這位做夢人，他坐起身來，口述一下他的夢，又去睡覺，也許會做更多的夢。

　　研究者們發(fā)現(xiàn)，一個人在剛做完一個夢時就被叫醒，通常他會記住夢的全部內(nèi)容。如果再讓他多睡五分鐘，他對夢的記憶會完全消失。
