Everyone must go to bed early（早）and get up early, or we won’t be healthy and clever.

Is this true? Perhaps（可能）it is. The body must have enough（足够）sleep. Children of your age need ten-hour sleep every day. If you don’t go to bed early, you will not have enough sleep. Then you can’t think properly（完全地）and can’t do your work properly. You’ll not be clever.

Some people go to bed late and get up late. That is not good for them. We must sleep at night when it is dark（黑的）. The dark helps us to sleep soundly. When the daytime comes, we must get up. This is the time for exercise. If you lack（缺乏）exercise, it becomes weak（虚弱的）. Exercise keeps a strong body.

Exercise helps the blood（血液）flow（流动）around inside the body. This is very important. Blood takes food to all parts of our body. The brain（大脑）also need blood, we think with our blood. If we keep our body healthy and take exercises, we can think better.

What will you do if weight keeps going up? Here are ideas to help you stay healthy:
Don’t sit around
Stay active. Try to exercise 30 to 60 minutes every day. Your exercise doesn’t have to be hard. Start small. Take the stairs instead of the elevator(电梯). Walk or ride a bike to places such as school or a friend’s house. Help your mum with housework, such as cleaning windows or the bathroom. It all burns fat. Make changes from time to time so you don’t get bored: Try running, biking, skating. There are many choices. Don’t spend long hours watching TV or playing video games. Even reading a book burns more fat.
Eat healthy
Truly different kinds of food and get enough fruits and vegetables each day. Drink water and low fat milk instead of soft drinks like Cola. Stay away from fast food. Eat when you are hungry, not when you are bored or because you can’t think of anything else to. Don’t eat meals or snacks while watching TV because you’ll probably end up eating more than you need. Some worry so much about their weight that they don’t eat breakfast. This is a bad idea. Teenagers need enough food. If not, you won’t get the nutrients you need to grow normally.
Don’t rush to go on a diet
Even if you are a little heavier than your fiends, you still may be normal. Remember to talk to doctors and your parents before you decide to lose weight.
