Oh, hey there!

No, excuse me, I'm so sorry.

I'm kind of tired today because I didn't get enough sleep last night.

Aw, thanks Squeaks, but I think I'll be alright.

You probably already know that sleep is really important, and that we need to get plenty of it.

Doctors think that most kids need to get about 10 to 12 hours of sleep every day.

But sometimes it's hard to go to bed when you're supposed to, especially if you don't feel tired.

That's why it helps to know what's going on while you're snoozing away at night, and why sleep is so important.

Think about all the things you do during the day.

You probably spend a lot of your day playing, or maybe going places like to school or to the store.

All those activities and anything else you do take energy.

Your body still uses energy when you sleep, but it uses less of it.

Since your body uses less energy when you sleep, it has a chance to save some of that energy for later.

So you feel good when you wake up the next morning and you're ready to take on another day.

Sleep also gives your body a chance to focus energy on things that keep you healthy.

For example, your body uses energy to heal and to grow while you sleep.

Sleep also gives your body a chance to use energy to fight off the germs that can make you sick.

So sleep is really important for your whole body.

But there's one special part of your body that really needs sleep.

Sleep.

Your brain.

Sleep not only gives your body a rest, it gives your brain a rest, too.

Your brain is super busy during the day.

It works really hard to make sense of all the things you see, smell, and hear.

It makes sure that all the parts of your body are working together, it helps you make decisions, and it helps you learn new things.

And those are just some of your brain's jobs.

Your brain doesn't stop working when you sleep,

but it does have a chance to slow down for a bit and to kind of figure things out.

While you sleep, your brain organizes the things you learned about during the day, to help you remember them for later.

Your brain also sorts out your feelings while you sleep.

Scientists have also found out that your brain needs sleep to help you concentrate,

so you can be better at solving problems at home and at school.

Wow, there's a lot going on while you sleep, even if you don't remember it when you wake up!

There is so much going on, in fact, that your body usually makes you feel pretty terrible when you don't get enough sleep.

Too little sleep can make you feel tired, and it can make it harder for you to concentrate and solve problems.

And since your brain helps sort out your feelings while you're sleeping, you can also feel cranky or crabby when you don't get enough sleep.

So what can we do to make sure we get enough sleep?

First, doctors and other sleep experts say you should have a sleep routine.

That means we should try and do the same things every night before we go to bed.

A sleep routine helps your body realize that it's time to go to sleep.

A good routine might include reading a story, having a bath, or maybe listening to some soft music.

It should also mean going to bed at about the same time every night, and getting up about the same time every morning.

That's one of the reasons it's important to have a bedtime.

One thing that shouldn't be part of your sleep routine is watching TV, or using a tablet or phone.

That's because the special light from their screens can send a signal to your body that it's daytime, even when it's really time for bed.

So now you know why it's so important to get a good night's sleep.

I think I'm gonna go take a nap.

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
