Unit 12 F “Nap”

Passage F
Nap
Sleep is good for us. Sleep let us rest, and it helps us grow. People sleep for a long time every night. Sometimes people sleep for short time in the day. A short sleep is called a nap. Cats always take very short naps, so a short nap is called a catnap. Catnaps are good for people, too.
小睡
睡眠对我们有好处。睡眠让我们休息，并且让我们成长。人们每天晚上都睡很长时间。有时人们在白天睡一小会儿。这样短暂的睡眠叫做小睡。猫总是非常短暂的小睡，因此我们把短时间的小睡叫做猫打盹，猫打盹对人们也是有好处的。
