《睡觉，我们为什么需要它？》英语音频

Sleep, why do we need it?

“Why do we sleep?ask smarty cat.

“We sleep to give our bodies a chance to rest and grow,smarty cat,”say who and how, the grumpy little owls.

“Everyone needs to sleep,”whispers who.

“Most sleep at night but owls like us sleep during the day.”

“Yes!that's why I'm so grumpy, smarty cat!

You're always waking me up!”mumbles how.

“It doesn't matter where we sleep as long as it's peaceful and snug.

Some sleep in trees and others sleep in holes.

And some sleep in beds, just like you,smarty cat.

You can have big long sleeps or little sleeps called naps.”

“Catnaps!”yawn smarty cat.

“when we sleep our bodies recharge with energy so we are fresh for the next day.”says how.

Sleeping gives our brains a chance to rest.

And sometimes we dream.

Dreams can be strange.

And they can be funny!

But it's healthy for us to dream.

While we rest, our bodies also mend our muscles and do some growing.

Our bones and nails grow,and we even grow new hair.

Hair and nails only grow a tiny bit at a time so you can't see the difference from one

sleep to the next.

“when we have enough sleep our bodies and brains work much better!”

And that's why we need to sleep smarty cat!”says who.

“Hey! smarty cat,”says who.

“What do you call a bull when he's asleep?”

“I don't know,”says smarty cat.“What?”

“A bulldozer!”
