How do you remember the way to your house? Where do dreams come from? It is your brain 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 are sleeping. What's more, another scientist in the U. S. A. 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 brain "cool", which makes us think quicker.
Here
