Our questions were about exercise, use of the Internet and watching TV. Here are the results. • We 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! • We all know that many students often go on-line, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at lease three or four time a week. Most students use it for fun and not for homework. 2b: What do No. 5 High School Students do in their free time? • The 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 TV four 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. • It 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 as playing spots is fun, and you can spend time with your friends and family as you play together. And remember, “Old habits die hard”, So stat exercising before it’s too late! 阅读课文，勾画记忆课文短语 • in free time • ask sb. about sth. • six times a week • one or three times a week • Three or four times a week • not at all • go online • be surprised at o hat • use the internet • at least • for fun and homework • for fun and exercise • the answerkey to • the most important • It is good nice healthy interesting to • by using internet • by watching TV • the best way • it is healthy for mind and body • such as • spend time with • old habits die hard 附录 课本练习 1a.Look at the picture.
