Explanations and extension

探究一、

Here are the results. 下面是结果。这是一个倒装句型，基本结构为

“Here/there +be/动词+名词。”

e.g. ① Here (be) your book.

② Here (come) the bus.

( ① is ② comes )

探究二、

We found that only fifteen percent of our students exercise every day.

我们发现只有百分之十五的学生每天锻炼。percent 的意思是“百分之...”，没有复数形式。

①如要表示百分之几，用“数词+percent”，e.g. 1%-one percent, 99%-ninety-nine percent;

②提问用“how many”, e.g. 百分之多少--“how many percent ”

③如果修饰名词则在其后加“of+名词”。e.g. 百分之三十的学生 thirty

percent of the students；百分之多少的学生 how many percent of the students.

④含 percent 的短语作主语时，其后的谓语动词由它所修饰的名词来决定。

e.g. Twenty percent of the students agree with you.

百分之二十的学生赞同你。

Forty percent of the time passes.百分之四十的时间过去了。

小试身手

How many percent of the students （be）boys in your class?

你们班多少学生是男生？( are)

探究三、

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回答也颇有意思。

the answer(s) to… ……的答案

探究四、

Although many students like to watch sports, game shows are the most popular.

although 是连词，意为“虽然、尽管”，引导让步状语从句，可以与 though 互换，但不能与 but 同时出现

在一个句子中。也就是说，在同一个句子中，有 although 就没有 but，反之亦然。

e.g. Although He is ill, he goes on working.=He is ill, but he goes on working.

探究五、

It’s good to relax by using the Internet or watching game shows, but we think the best way to relax is through

exercise. 通过上网和看游戏类节目来放松没错，但我们认为最好的放松方式还是通过锻炼。

⑴ 此句是“It’s + adj. (for sb.) to do sth.（对某人来说）做某事是……的”，it 作形式主语，真正的主语是后

面的动词不定式。e.g. It’s important(for us) to learn English well.

小试身手

①It is interesting ____ _____(see)English films.

②It is good （exercise） every day .

( ① to see ② to exercise)

by doing sth. ⑵ 通过做某事

the best way to do sth./the best way of doing sth. ⑶做某事的最好方法

探究六、

Old habits die hard.旧习难改。（英语谚语）(die-dying)

探究七、

So start exercising before it’s too late! 所以赶快锻炼起来，不要等到来不及了！

It’s too late 意为“为时太晚；来不及了”，是英语的一个常用表达。
