percent 名词，意为“百分之……”
构成：基数词+percent
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。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。1）句子主语为 the answers ，故谓语用 were。
2） 表示“…的答案”要用“answer to…”
如：
There’s no easy answer to this problem.
这个问题没有简单的答案。
Her answer to your question is a big “NO”!
她对你所提的问题的答案是一个大大的“不”字！[来源:学科网ZXXK]3）表示“有关…的（问题）”用question about…
如：
He asked us some questions about our daily habits.
他问了一些有关我们日常习惯的问题。
Her questions about you were not so friendly.
她有关你的那些问题并不那么友善。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。5.It’s good to relax by using the internet or watching game show ,but we think the best way to relax is through exercise.上网或看游戏类节目是很好地放松方式，但我们认为最好的放松方式是锻炼。
（1）It’s+形容词+to do sth意为（对某人来说）做某事是…….
（2）by doing sth 意为 通过做某事
(3 ) through介词，意为“以；凭借；通过”。6. 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。注意：其后面不可列举出所有的事物。如：
我了解四种语言，例如英语、汉语。
I know four language, such as, English and Chinese. (√)
I know four language, such as, English, French, Japanese and Chinese. (×) 7.Exercise such as playing sports is fun ,and you can spend time with your friends and family as you play together.比如进行体育活动这方面的锻炼时有趣的，当你们一起活动的时候你可以和朋友、家人一起度过美好的时光。
spend…..with sb意为与某人度过…….
【拓展】spend……（in）doing sth.花费时间或金钱做某事。
He always spends his time playing soccer.7. 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。
