Some people think that they will get ill if they use their brains（大脑）too much.  It is not true.  Through many researches, scientists show us that the more you use your brains, the better they will be, and the wiser you will bee.
Of course, if you want to keep your mind clear and be energetic（充满活力的）, you must take a proper rest and study properly.  To the teenagers, using their brains in the morning is good for their health.
There are many ways to rest.  One is a peaceful rest.  Sleep is a peaceful rest.  Another is an active rest.  For example, take a walk outdoors, do morning exercises every day.  To change the way of the brains’activities（活动）is also a good way to rest.
In everyday life, to eat some eggs, meat, fresh vegetable and fruit is also good for the brains.
Wish you a wise man and a happy life.
