Language points
1. We found that only fifteen percent of our students exercise every day.
percent n.“百分之……”沒有復(fù)數(shù)形式
基數(shù)詞+percent+ of...“百分之……的……”作主語時(shí)，謂語的數(shù)和of后的名詞，代詞保持一致。
► Seventy percent of the boys like playing computer games.
男生中70%喜歡玩電腦游戲。
► Thirty percent of time passes.
百分之三十的時(shí)間過去了。
2. Although many students like to watch sports, game shows are the most popular.雖然很多學(xué)生喜歡看體育節(jié)目，但游戲節(jié)目是最受歡迎的。
although是連詞，意為“雖然，即使，縱然”，引導(dǎo)讓步狀語從句，相當(dāng)于 though，大多數(shù)情況下兩者可互換。注意：although 引導(dǎo)的從句不能與but 連用，有although 就沒有 but（即 although but不同現(xiàn)）。
Although it rained, the boys still played outside.
= It rained, but the boys still played outside.
盡管天下雨了，但男孩們?nèi)栽谕饷嫱嫠！?/p>
Ex.He didn't say sorry to me. He was wrong .(合并為一句）
He didn't say sorry to me________he was wrong.
3....but we think the best way to relax is through exercise.
through prep. 以，憑借，穿過
eg.Light comes in through the window.
4. And twenty percent do not exercise at all!
百分之二十的學(xué)生根本不運(yùn)動(dòng)！
not … at all “一點(diǎn)也不”，注意：not代表了所有否定句，次結(jié)構(gòu)可理解為在否定句末加上at all加強(qiáng)否定句語氣。
拓展：在口語中單獨(dú)說 not at all, 可用來表示“不用謝”“沒關(guān)系”。
► The story isn’t interesting at all.
那個(gè)故事一點(diǎn)也沒有趣。
► They didn’t enjoy the vacation at all.
他們根本不喜歡那次旅行。
► The old man can hardly ever use the computer at all.
那位老人一點(diǎn)也不會(huì)用電腦。
5. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together.
such as 用來舉例，意為“例如；諸如此類的；像······那樣的”，結(jié)構(gòu)常為：名詞+ such as + 例子。
注意：其后面不可列舉出所有的事物。
► I know four languages, such as, English and Chinese.
我了解四種語言，例如英語、漢語。
► She likes animals such as rabbits and birds.
她喜歡像兔子、小鳥這樣的小動(dòng)物。
6. … but we were surprised that ninety percent of them use the Internet every day.
surprised 形容詞，意思是“感到驚訝的”，修飾人，surprising “令人驚訝”，修飾物。
常用結(jié)構(gòu)：
1）be surprised at sth 對(duì)某事感到驚訝
2）be surprised to do sth 做某事而感到驚訝
3）be surprised + that從句 因……而驚訝
► 我們對(duì)這個(gè)消息感到很驚訝。
We are surprised at the news.
► 我在這里見到你很驚訝。
I am very surprised to meet you here.
7. So start exercising before it’s too late!
所以要趕快鍛煉起來，不要等到來不及了。
start doing sth/to do sth=begin to do sth/doing sth 開始做某事
it’s too late 為時(shí)太晚；來不及了
it’s too late與before共同組成從句，表示“不要等到為時(shí)已晚；不要等到來不及的時(shí)候；趁著還來得及 ”。
► Now you know you’re wrong, but it’s too late.
現(xiàn)在你知道你錯(cuò)了，但是已經(jīng)太晚了。
► 你應(yīng)當(dāng)更加用功，別等到為時(shí)過晚而趕不上了。
