简介 几乎所有动物都需要睡觉来保持健康 不过睡觉可能会很危险哦 别的动物可能会捕食睡着的动物 动物们有很多不一样的睡觉方式，能帮助它们保障自身安全 其中有些方式说不定会让你大吃一惊哦

Sleeping Upside Down Almost all bats sleep upside down. They hang by their toes from a branch or from the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.

倒着睡觉 几乎所有蝙蝠都是倒着睡觉的 它们用脚趾勾住树枝或者洞穴顶倒挂着 待在高处，蝙蝠就不会被大多数其他动物伤害 要是遇到危险，它们直接飞走就行

Sleeping the Most and the Least Little brown bats win the prize for sleeping the most. They sleep as much as 19 hours a day. These bats are only awake for a few hours after the sun goes down. They may get up again for a little while before the sun rises. The rest of the time is for sleep, sleep, sleep.

睡得最多的和睡得最少的 小棕蝠拿到了“睡得最多奖”哦 它们一天最多能睡19个小时呢 这些蝙蝠只有太阳下山后才会醒几个小时 太阳升起前它们可能还会再醒一小会儿 剩下的时间就全用来睡、睡、睡啦

Giraffes win the prize for sleeping the least. They lie down when they sleep. They rest their heads on their bodies or on the ground. Every few hours they sleep for about 10 minutes. Giraffes are not safe if they sleep for long periods.

长颈鹿拿到了“睡得最少奖” 它们睡觉的时候会躺下来 会把脑袋靠在自己身上或者放在地上 每隔几个小时它们会睡10分钟左右 长颈鹿要是睡太久的话会有危险的

Sleeping with half the brain. A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.

用半颗大脑睡觉 海豚每次睡觉的时候只有半颗大脑在休息哦 它必须保持清醒才能呼吸，还要留意有没有危险 为了安全，海豚妈妈和宝宝可以连续两个月都不睡觉哦
