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 perc

ent 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 it’s too late!

1. We found that only fifteen percent of our students exercise every day. percent 名词，意为“百分之??” e.g. Eighty percent of the students in our class exercise every day. 我们班里80%的学生每天都锻 炼。

【注意】
percent做主语时，谓语动词的数要根据其后面的名词来 确定。 e.g. Fifty percent of the apples are bad. 50%的苹果都坏了。 Twenty percent of the meat is in the fridge. 20%的肉都在冰箱。 若要询问百分率，或笼统表达百分率的高低，应使用 percentage一词，而非percent;且疑问词用what, 而非how many 或how much. What percentage of …= How many percent of +名词复数

2. And twenty percent do not exercise at all! not … at all 意为“一点也不”， not应 和be动词、助动词或情态连用。 e.g. The story isn’t interesting at all. 那个故事一点也没有趣。 They didn’t enjoy the vacation at all. 他们根本不喜欢那次旅行。 The old man can’t use the computer at all. 那位老人一点也不会用电脑。

3. The answers to our questions about watching television were also interesting. 对我们提出的有关看电视的问题的答案也挺 有意思。

4.Although many students like to watch sports, game shows are the most popular. 虽然很多学生喜欢看体育节目，但游戏类节目 是最受欢迎的。
although 为连词，意为：“虽然，尽管”。 注意：在英语中，当表示“虽然…，但是….”这 样的意思时，although和but不能在同一个句子中 使用。也就是说

，在一个句子中，有although就没 有but ，反之亦然。如： Although the car is old , it still runs well. =The car is old , but it still runs well. 这辆小车旧了，但是依然跑得不错。

[中考链接] (2012 成都) My cousin knows a lot about C geography, ______ he is only four years old. A. because B. so C. although

5. Exercise such as playing sports is fun… such as 意为“像??这样”，表示列 举。 结构常为：名词+ such as + 例子 e.g. She likes animas such as rabbits and birds. 她喜欢像兔子、小鸟这样的小动 物。

5. So start exercising before it’s too late! 所以赶紧锻炼起来，不要等到来不及了。
It’s too late 字面意思为“为时太晚，来不及了” 是英语的一个常用表达。如： Now you know you are wrong , but it’s too late. 你现在知道错了，已经太晚了。 句中， It’s too late 与before共同组成从句，表示 “不要等到为时已晚；不要等到来不及的时候； 趁还来的及”。如： You should work harder before it’s too late to catch up.你现在用功还赶得上。
