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.
2b
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 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!

although是连词，意为“虽然，即使，纵然”，引导让步状语从句，相当于 though，大多数情况下两者可互换。注意：although 引导的从句不能与but 连用，有although 就没有 but（即 although but不同现）。

not … at all “一点也不”，注意：not代表了所有否定句，次结构可理解为在否定句末加上at all加强否定句语气。
拓展：在口语中单独说 not at all, 可用来表示“不用谢”“没关系”。
5. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together.

注意：其后面不可列举出所有的事物。
温馨提示：such as 可与like通用，所举例子只能为单词和短语，但for example 所举例 子要为句子。
