     How do you remember the way to your house? Where do dreams come from? It is your brain (大脑) that

does these things. A British scientist showed that "sleep can improve one's memory." It's not a dream for

students to study when they sleep. In fact, your brains is working day and night. If you learn words before

bed, a certain part of the brain may help you to remember the words while you sleep. What's more, another

scientist in the USA found that there was a "talent button (天才按钮)" in the human brain. It might make a

person more talented.

    There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two

bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning (打哈欠) keeps our brains "cool", which makes us think quicker.

     Here are some pieces of advice to keep a good brain:

     ● Eat healthy food.

     ● Get a lot of playtime or exercise. 

     ● Don't drink or smoke. 

     ● Use your brain a lot.
