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 percent 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!
3.We found that only fifteen percent of our students exercise every day.
我们发现只有15%的学生每天锻炼。
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。4. four to six times a week
每周四到六次注意这种表达, “to”为介词。
翻译：
每月一到三次
one to three times a month
once or twice a month
每月一次到两次
two or three times a month.
每月两次到三次5. And twenty percent do not exercise at all!
20%的学生根本不锻炼。
not … at all 意为“一点也不，根本不”， not位于句中，at all 放在句尾。
eg. 她根本就没有帮忙做家务。
She doesn’t help with housework at all.
6. 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：
Her answer to your question is a big “NO”!
她对你所提的问题的答案是个 大大的“不”字！3）表示“有关…的问题”用question about sth./ doing sth.
如：
He asked us some questions about our English exercises.
他问了一些有关我们英语练习的问题。7.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：1.不能和but, and , so在同一个句子中使用。
2.可与yet, still连用
eg.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。
8. It is good to relax by using the ..., ... the best way to relax is through exercise.
通过上网或看游戏节目是很好的放松方式，但我们认为最好的方式是通过锻炼。
1）It is good to do sth. 做某事是好的
It is +adj. + to do sth. 做某事是怎样的，其 中It是形式主语，真正的主语是to do sth.
eg. It is good to exercise in the morning.
2) the best way to do sth. 做某事最好的方法8. It is good to relax by using the ..., ... the best way to relax is through exercise.
通过上网或看游戏节目是很好的放松方式，但我们认为最好的方式是通过锻炼。
3）通过：by & through
by +具体工具名词/doing
through+手段或媒介的名词
eg. He got the job ________ his father.
You passed the exam _____ working hard.
throughby1.across 表面穿过（马路，街道）
eg. across the road/ street
2.through 内部穿过（门，窗户，森林）
eg. through the door/ window穿过：through & aross9. Exercise such as playing sports is fun…
such as 意为“像……这样，比如...”，表示列举。
结构常为：名词+ such as + n./ doing.
e.g. She likes animas such as rabbits
and birds.
她喜欢像兔子、小鸟这样的小动
物。10.spend (v.) 花费（时间或金钱），过去式为spentsb. spends/ spent +时间/金钱+on sth./ (in) doing sth.
某人花费时间/金钱在某事上/做某事It takes /took sb. +时间+ to do sth.
（It 是形式主语）
某人花费时间做某事 11. So start exercising before it’s too late!
it’s too late 为时太晚；来不及了与before共同组成从句，表示“不要等到来不及的时候；趁着还来得及 ”。
e.g.
You should work harder before it’s too late to catch up.
你应当更加用功，别等到为时过晚而赶不上了。（你现在用功还赶得上。）3a Look at the information in the chart
