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 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 ten 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 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!

短语归纳Task3:Read and translate!翻译： 第五中学的学生们在业余时间做什么？
上个月我们询问了我们的学生有关他们业余时间活动的问题。我们的问题是：锻炼、上网和看电视。下面是结果：
我们发现只有15%的学生每天锻炼，45%每周锻炼4到6次，20%一周仅一到三次。20%根本就不锻炼！
我们知道很多学生都经常上网，但我们吃惊的是90%的学生每天上网，剩下的10%没有上网3到4次，大多数学生上网是玩（游戏）而不是做作业。
对于我们有关看电视的问题的回答也蛮有意思。只有2%的学生每周看1到3次电视，13%每周看4到6次，85%每天都看！尽管很多学生喜欢看体育节目，但娱乐节目最受欢迎。
通过上网和观看娱乐节目来放松是好的，但我们认为最好的方松方式是通过锻炼，这对身心都是健康的。通过体育运动来锻炼是有趣的，你可以花一些时间同你的朋友和家人一起做运动。记住，“积习难改”，所以尽早开始锻炼吧What can we learn from the article?The best way to relax is through exercise!Homework: Make a survey:What do your parents do in their free time?1、percent :百分数
