What Do No. 5 High School Students Do in Their Free Time？
①Last month we asked our students about their free time activities. Our questions were about exercise, use of the Internet and watching TV. Here are the results.
②We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. And twenty percent do not exercise at all！
③We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. Most students use it for fun and not for homework.
课文P13(2)
④The answers to our questions about watching television were also interesting. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TVfour to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sports, game shows are the most popular.
⑤It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. It is healthy for the mind and the body. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together. And remember, “Old habits die hard. " So start exercising before it's too late！

拓展延伸
There is an old saying: Early to bed and early to rise makes a man healthy, wealthy and wise. It means we should go to bed early and get up early next morning. By doing this, we will be in good health. And we'll be rich and clever. It is true that our bodies need to have a ten-hour sleep every night. Those who do not have enough sleep can't do their work well. They will not be clever and they may not be wealthy in the future.
The body needs exercise as well. Walking, running, jumping, riding bikes and playing games are all exercise. Exercise helps to keep the body strong and fit. It also helps the blood(血液)to move around inside the body. The blood takes food to all parts of the body. The head needs blood, too. So exercise helps people to think better.
