What Do No.5 High School Students Do in Their Free Time?,What do No. 5 High school students do in their free time Last 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. We found that only 15 percent of our students exercise every day. 45 percent exercise four to six times a week. 20 percent exercise only one to three times a week .And 20 percent do not exercise at all ! We all know that many students often go online, but we were surprised that 90% of them use the Internet every day. The other 10% use it at least three or four times a week. Most students use it for fun and not for homework.,2b,The answers to our questions about watching television were also interesting. Only 2% of the students watch TV one to three times a week.13% watch TV four to six times. And 85% watch TV every day ! Although many students like to watch sports, games 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 late!,它对于大脑和身体是健康的。,Read the article and complete the pie charts,15,45,20,20,90,10,2,13,85,2b,15%,20%,45%,0%,20%,90%,10%,85%,2%,13%,1. ask sb. about sth. 向某人询问某事 2.主语+ find+ that 从句 发现 3.four to six times a week 每周四至六次 4.notat all 根本不 一点也不 5.go online, use the Internet 上网 6. be surprised 感到惊奇 7.at least 至少 8. three or four times a week 每周三到四次 9. by doing sth. 通过做某事 10.
