有人曾做过一个有趣的调查,那是关于动物的睡眠时间的。据说,懒猴(南美产)每天睡20小时;狮子每天睡10小时;马每天睡4小时(站着睡);长颈鹿每天睡20分钟;海豚每天睡0小时(不睡觉)。
Someone has done a funny investigation, it is about the animal’s sleep time. It is said that the sloth monkey (South American production) sleeps 20 hours a day; the lion sleeps 10 hours a day; the horse sleeps 4 hours a day (standing sleep); giraffe sleeps 20 minutes a day; dolphins sleep 0 hours a day (do not sleep).
