it的用法(Ⅰ)

it作人称代词

1．it的最基本的用法是作代词，主要指刚提到的事物，以避免重复。

①Xi'an is a beautiful city, isn't it?

西安是一座美丽的城市，不是吗？

2．it也可以指动物或婴儿(有时也可指未知性别的人)。

②The baby cried because it was hungry.

这个婴儿哭是因为饿了。

it作非人称代词

it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度和环境等，称为非人称代词。

③It is a long way to the factory.

到这家工厂有很长一段路。

it作形式主语

it替代作主语的从句、动词不定式、动名词置于句首，而把真正的主语置于句尾。

1．代替不定式作主语

(1)It be＋adj.＋(for sb.) to do sth.

(此处的adj.多为描述事件的形容词)

④It is illegal for a teenager to drive a car without a license.

青少年无照驾驶是违法的。

(2)It be＋adj.＋of sb. to do sth.

(此处adj.多为描述人的形容词)

⑤It's kind of you to help me with the problem.

你帮助我解决这个问题，真是太好了。

2．代替动名词作主语

常见句型为：

It is no good/use doing ... 　做……是没有好处/没用的

It's worthwhile doing ... 　做……是值得的

It's useless doing ... 　做……是没用的

⑥It's no use crying over spilt milk.

覆水难收。

3．代替主语从句作主语

(1)It is＋adj.＋that从句

此句型中常见的形容词为：clear, obvious, true, likely, possible, certain等。

⑦It's very clear that he made a mistake.

很明显他犯错了。

(2)It is＋v.ed＋that从句

＝sb./sth. is＋v.ed＋to do

此句型中常见的过去分词为：said, reported, learned, believed, thought, known, told, hoped等。

⑧It is said that he has gone to Beijing.

→He is said to have gone to Beijing.

据说他已经去北京了。

(3)It is＋n.＋that从句

此句型中常见名词为：a pity, a shame, an honour, a good thing, a fact, a surprise等。

[重点提示]　

此句型中，that后从句常用虚拟语气，即“should＋动词原形”，表示出乎意料。若无此意义时，则无需用虚拟语气。

It's a pity that such a thing should happen  in your class.

很遗憾，那样的事竟然发生在你们班。

It's a pity that he is  ill.

很遗憾，他生病了。

it作形式宾语

当复合宾语中的宾语是不定式、动名词、宾语从句时，往往把宾语置于宾补之后，用it作形式宾语。此句型中常见动词有：think, believe, make, find, consider, feel等。

⑨I think it no use arguing with them.

我认为和他们辩论没用。

⑩He made it clear that he was not interested in the subject.

他明确表示他对这个学科不感兴趣。

[重点提示]　

有些动词如：like, appreciate, see to, dislike, hate等不能直接接宾语从句，需先用it作形式宾语，再接一个宾语从句。
