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.
