Three questions about students ' free time activities.
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 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 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.

5. We found that only fifteen percent of our students exercise every day. (教材P13 2b)

Point
(1) percent作名词，意为“百分之……”，单复数同形，如：once percent百分之一，thirty percent百分之三十。
Twenty percent of the students agree with you.
Thirty percent of the time passes.
(2) “基数词+percent+of the+名词”结构作主语时，谓语动词的单复数由该结构中的名词来决定。
6. And twenty percent do not exercise at all!
(1)not... at all 表示强烈的否定，意为“根本不；一点儿也不”，at all通常位于句尾。

8. It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise.
通过使用网络或观看游戏类节目来放松是件好事，但我们认为最佳的放松方式是通过锻炼。
1) It is + 形容词 + (for sb.) to do sth. (对某人来说)做某事……
e.g. It is important for us to learn from others.
对我们来说向别人学习很重要。
2) It is good to relax ... 中的to relax在句中作真正的主语，it是形式主语; ... the best way to relax ... 中的to relax在句中作定语, 修饰前面的名词way。
9. Old habits die hard.
The famous singer died at the age of thirty-two.
The flower has been dead for more than ten days.
die常用作不及物动词，意为“消失；灭亡；死亡”其后不能直接跟宾语，且die是短暂性动词，不能与表示一段时间的状语连用。如果表示状态，与一段时间连用，要用be dead。
death n.死亡
【拓展】
die v. 死亡
dead adj. 死的
dying adj. 垂死的
