ninety percent f them use the Internet every day. The ther ten percent use it at least three r fur times a week. Mst students use it fr fun andnt fr hmewrk.The answers t ur questins abut watching televisin were als interesting.
Only tw percent f the students watch TV ne t three times a week. Thirteen percent watch TV fur t six times a week. And eighty-five percent watch TV every day! Althugh many students like t watch sprts, game shws are the mst ppular.
It is gd t relax by using the Internet r watching game shws, but we think the best way t relax is thrugh exercise. It is healthy fr the mind and the bdy. Exercise such as playing sprts is fun, and yu can spend time with yur friends and family as yu play tgether. And remember,
“ld habits die hard”. S start exercising befre it’s t late!

1.We fund that nly fifteen percent f ur students exercise every day.
percentn.“百分之……”没有复数形式基数词+percent+ f...“百分之...的...”作主语时， 谓语的数和f后的名词，代词保持一致。
Seventy percent f the bys like playing cmputergames.男生中70%喜欢玩电脑游戏。Thirty percent f time passes.百分之三十的时间过去了。
2. Althugh many students like t watch sprts, game shws are the mst ppular.虽然很多学生 喜欢看体育节目，但游戏节目是最受欢迎的。
althugh是连词，意为“虽然，即使，纵然”，引导 让步状语从句，相当于 thugh，大多数情况下两者 可互换。注意：althugh 引导的从句不能与but 连用， 有althugh 就没有 but（即 althugh but不同现）。
Althugh it rained, the bys still played utside.
= It rained, but the bys still played utside.尽管天下雨了，但男孩们仍在外面玩耍。Ex.He didn't say srry t me. He was wrng . (合并为一句）He didn't say srry t mea_l_t_h__u_g_h_he was wrng.

4..And twenty percent d nt exercise at all!
百分之二十的学生根本不运动！nt … at all “一点也不”，注意：nt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 nt at all, 可用来表示“不用谢”“没 关系”。The stry isn’t interesting at all.那个故事一点也没有趣。They didn’t enjy the vacatin at all.他们根本不喜欢那次旅行。The ld man can hardly ever use the cmputer at all.那位老人一点也不会用电脑。
5. Exercise such as playing sprts is fun, and yu can spend time with yur friends and family as yu play tgether.
such as 用来举例，意为“例如；诸如此类的；像······那 样的”，结构常为：名词+ such as + 例子。注意：其后面不可列举出所有的事物。I knw fur languages, such as, English and Chinese.我了解四种语言，例如英语、汉语。She likes animas such as rabbits and birds.她喜欢像兔子、小鸟这样的小动物。
温馨提示：such as 可与like通用，所举例子只能为 单词和短语，但fr example 所举例 子要为句子。 试对比：He des sprts like/such as running every day. He likes sprts.Fr example, he runs every day.
6. … but we were surprised that ninety percent f them use the Internet every day.
surprised 形容词，意思是“感到惊讶的”，修饰人， surprising “令人惊讶”，修饰物。 常用结构： 1）be surprised at sth 对某事感到惊讶be surprised t d sth 做某事而感到惊讶be surprised + that从句 因……而惊讶我们队这个消息感到很意外。We are surprised at the news.我在这里见到你很意外。I am very surprised t meet yu here.
7. S start exercising befre it’s t late!所以要赶快锻炼起来，不要等到来不及了。start ding sth/t d sth=begin t d sth/ding sth 开始做某事it’s t late为时太晚；来不及了it’s t late与befre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；趁着还来得及 ”。Nw yu knw yu’re wrng, but it’s t late.现在你知道你错了，但是已经太晚了。你应当更加用功，别等到为时过晚而赶不上了。Yu shuld wrk harder befre it’s t late t catch up.
