    Some people go to bed late and get up late. This is not good for health. We must sleep at night when it is dark. The dark helps us to sleep soundly（踏实地）.

When the daytimes comes, we must get up. This is the time for exercise. If we lack（缺少） exercise, we'll become weak. Exercise keeps us 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 also needs blood, we think with our blood. So we can think better if we keep our body healthy and take exercise.
