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 online, but we were surprised that ninety percent of them use the Internet every day. The other then percent use it at least three or four times a week. Most students use it for fun and not for homework. 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 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 its too late!c.Carefully reading and complete the pie chart below._ % every day Exercise_ % 3 or 4 times a weekUse of the Internet_ % every day _ % 4-6 times a week_ % 1-3 times a week_ % no exercise102015204590_ % 4-6 times a weekWatch TV_ % 1-3 times a week_ % every day 85132_ % 4-6 times a weekPlay sports_ % 1-3 times a week_ % every day 502525d.Carefully reading and answer questions(work in pairs) (2c)1.
