【重点句型】
1. Last month we asked our students about their free time activities.
上个月我们询问了学生们关于他们的业余活动情况。
ask sb. about sth. 意为“问某人关于某事的情况；就某事询问某人”。
例：她询问了他的健康状况。 She asked him about his health.
我向我的老师询问今天的家庭作业。I ask my teacher about today’s homework.
(1)ask for “要；要求；请求”，宾语是物，表示 （向某人）要……。ask sb. for sth. 向某人要某物。
例：你可以向警察求助。 You can ask policeman for help .
(2) ask for a leave “请假”
例：你能帮我请个假吗？Could you help me ask for a leave
2. Here are the results. 这是（调查）结果。

例：她来了。Here she (代词) comes (第三人称单数).
这里有一些香蕉。Here are (复数) some bananas (名词).
【拓展】

surprised作形容词，意为“感到惊讶的”。
常用结构：
be surprised at sth.“对……感到惊讶”；
be surprised to do sth.“做……而感到惊讶”；
be surprised + that从句，“因……而惊讶”。
例：你对这个结果感到惊讶吗？ Are you surprised at the result
他们对见到他感到很惊讶。They were surprised to see him.
我吃惊的是他及时来到了这儿。I’m surprised that he came here in time.
surprised 与surprising

上网或看游戏类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来放松。
(1)It’s +adj.+to do sth. 意为“做某事是……的”。
it是形式主语，真正的主语是后面的动词不定式。
例：在河里游泳是危险的。 It’s dangerous to swim in the river.
学好英语很重要。 It’s very important to learn English well.
在It’s+ adj. +for/of sb. to do sth.中,若adj.为important, useful, necessary, hard, easy等表示事物性质、状态或特征的词，用It’s + adj. +for sb. to do sth.；

5.We found that only fifteen percent of our students exercise every day.
percent 名词，“百分之……”百分数由percent来表示，构成方式：基数词+percent 。percent 没有复数形式，作主语时，根据所修饰的名词来判断谓语的单复数。
Seventy percent of the boys like playing computer games. 男生中70%喜欢完电脑游戏。
Thirty percent of time passes.百分之三十的时间过去了。
6. 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，但游戏节目是最受欢迎的。
although是连词，意为“虽然，即使，纵然”，引导让步状语从句，相当于though，大多数情况下两者可互换。注意：although引导的从句不能与but连用，有although就没有but
Although it rained，the boys still played outside.= It rained, but the boys still played outside.
尽管天下雨了，但男孩们仍在外面玩耍。
7. And twenty percent do not exercise at all!百分之二十的学生根本不运动！
not … at all 用于否定句，“一点也不”，not应和be动词、助动词或情态动词连用。另外，在口语中单独说 not at all, 可用来表示“不用谢”“没关系”。
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。
8. So start exercising before it’s too late!所以要赶快锻炼起来，不要等到来不及了。
start doing sth/to do sth=begin to do sth/doing sth开始做某事

What is the hardest sport in the world Some people say it's boxing (拳击)， because boxing is dangerous and boxers have to be strong and fast. Other people say the hardest sport is soccer.
However， most people say the hardest sport is the triathlon (三项全能). A triathlon is a race that includes three sports. First， racers swim. After that they ride bicycles and finally they run. In the most common triathlon， racers swim 1.5 kilometers， bike 40 kilometers， and run 10 kilometers. The winner is the person who finishes the race first.
In the past few years， there have been other races including three sports. However， they didn't use the word "triathlon". That word was first used to describe a race in California in 1974.
Triathlon racers have to train very hard for their races. Many of them swim and run. A lot of people also do things like yoga (瑜伽). They have many different ways to prepare， but they all have the same goal. They want to be in perfect shape.
To win the race， you have to be strong and smart. You should know how to save energy during the race.
