10.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 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.
