阅读短文,选择正确的答案。

     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 brain 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

foundthat 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.
