帮忙翻译一下这篇英语短文~

Sleep
Sleet is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you fist drift off into slumber, your eyes will roll about a bit, you temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep. slower your brain waves will be. Then about 40to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.
You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will slip gently back from stage 1 to stage 4 sleep----only to rise once again to the surface of near consciousness some 80 minutes later

可不可以告诉我这篇文章按正常速度朗诵需要多少时间?

Answer 1

如果你是考研的话，阅读时间应该不超过6分钟。
如果是中学生，我估计15分钟应该是上限了。

睡眠是人们日常生命循环的一部分，睡眠中有若干不同的阶段，他们当然也在上述循环中进行着。如果你通常能够正常的入睡，那么你的睡眠系统一般是这样的。
当你刚进入梦乡时，你的眼睛将做轻微的旋转，而你的体温则会缓慢的下降，肌肉将会放松，呼吸的频率会变慢而其声音通常会变轻。你的脑电波也是一样（指变慢和变放松）。你的脑电波为阿尔法脑波频率1，或稍慢一点，在接下来的半个小时左右里，随着你越来越放松，你的脑波将会减慢到阿尔法脑波频率2或3。你睡得越沉，你的脑必将越慢。40-60分钟以后，你差不多就没有意识了，这是你将达到最深度的睡眠。你的脑波将显示出目前已知的最慢的阿尔法脑波频率：4级。
整个夜晚你并不会一直保持这样的脑波状态，当你睡着大约80分钟后你的脑波活跃程度又将开始变得渐渐活跃起来。德尔塔脑波将消失，被活跃的脑波所取代。眼皮一下，你的眼睛开始飞快的旋转，就像你正在聚精会神的看着什么正发生在你眼前的事务。这种快速的眼睛运动大约持续8-15分钟，而我们称他为REM睡眠。在这段时间当中，你的身体将会再次变得放松，而你的呼吸将会再次由阿尔法脑波等级渐渐或读到阿尔法脑波等级4，于是，下一个80分钟的有意识阶段又到来了。
