One night, my sister wanted to sleep in the room to see why he woke up screaming every time we put him in his crib fast asleep.

一天，我姐姐打算睡在那个房间，想知道为什么每次我们把他放在婴儿床上熟睡时，他就会尖叫着醒来。

They also have more time for exercise and sleep, and tend to choose home cooking over fast food.

人们会有更多的时间来进行锻炼和睡觉，更多地在家做饭而不是吃快餐。

My energy remained fairly good throughout the fast, and the hunger was easily manageable, even there was no break for long stretches of sleep.

在禁食期间，虽然由于多相睡眠的原因，我并没有大段的睡眠和休息时间，但饥饿感也并不是非常强烈而且精神状态一直良好。

Dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep.

无梦睡眠则要浅得多。我们都看到过猫和狗在显然的酣睡中，有一点响动耳朵就会竖起来。

Other research has shown metabolism and sleep are connected, Fu says, but it's not clear yet whether short sleepers are thin because of a fast metabolism or just because they're just so darned active.

Fu说其它研究也表明新陈代谢和睡眠有一定的联系，但是现在还不能明确短睡眠者瘦是因为快速的新陈代谢还是仅仅因为他们太过分活跃了。
