一、it 作人称代词
1. it的最基本用法是作代词,主要指刚提到的 事物,以避免重复: Xi’an is a beautiful city, isn’t it? 2. 也可以指动物或婴儿(未知性别的婴儿或孩 子): Is this your dog?No, it isn’t.

二、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、环境等,称为非人称的it: 指天气: It is a lovely day, isn’t it? It is a bit windy. 2. 指时间: It was nearly midnight when she came back. 3. 指环境: It was very quiet in the café. 4. 指距离: It is half an hour’s walk to the city centre from my home.

三、it用作形式主语

替代作主语的从句、动词不定式、动名 词,而把真正作主语的从句、动词不定 式、动名词置于句尾。

1. 代作主语的动词不定式

(1)It be adj.(for sb.)to do sth. 此处adj. 通常为描述事件的形容词:easy,difficult, hard,necessary,unnecessary,possible, impossible,likely,unlikely,right,wrong, important,unimportant,legal,illegal,wellmannered,ill-mannered,polite,impolite,clear, obvious,certain,suitable,proper,fit,useful, useless,dangerous… It is illegal(for a teenager)to drive a car without a license.

(2)It be adj. of sb. to do sth. 此处adj. 通常为描述人的形容词:kind, unkind,nice,rude,cruel,considerate, thoughtful,thoughtless,careful, careless,silly,foolish,stupid,clever, wise,crazy. It's kind of you to help me with the problem.

(3) It替代作主语的动名词的常见句型 It's no good/use doing… It's(well)worth doing… It's(well)worth one's while doing/to do… It's(well)worth while doing/ to do It's no use crying over spilt milk.

2. it作形式主语替代主语从句
①It is adj. +clause It is clear ( obvious,true,possible, certain …) that ... 该句型中it 是形式主语,真正的主语是that 引导 的主语从句,常译为“清楚(显然, 真的……)” 是主语从句最常见的一种结构。例如: It is very clear that he’s round and tall like a tree.

②It is v-ed that…=sb./sth. is to do It is said (reported/ learned/believed /thought/known/told/hoped.....) that ... 该句型中的it 仍是形式主语,真正主语是that 引 导的主语从句;该结构常译为“据说(据报道, 据悉...)”。 It is said that he has come to Beijing. It is reported that another earth satellite has been put into orbit.

③ It is + noun +从句
It is a pity (a shame /an honor /a good thing/a fact /a surprise/... ) that ... 该句型中,that后的从句一般用虚拟语气(should + 动词原形),should可省去.表示出乎意料,常译为 “竟然”。没有这种意义时,则不用虚拟语气。例如: It is a pity that such a thing (should) happen in your class. 这种事竟然发生在你们班上,真是遗憾! It is a pity that he is ill. 他生病了,真遗憾!

四、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,往往把宾语放在它的补足 语后面,而用it 作形式宾语,放在宾语 补足语之前。
该句型中的it 作形式宾语,常用的动词有 think, believe, make, find, consider, feel等。

I think it no use arguing with him. 我认为和他争吵没有用。 I found it very interesting to study English. 我发现学英语非常有趣。 He made it clear that he was not interested in this subject. 他非常清楚地表示他对那门学科不感兴趣。

五、用于强调句型中
It is/was + 被强调部分 + that/who ...

It is not until + 被强调部分 + that ...
I met Tom in the park yesterday. 1) It was I who met Tom in the park yesterday. 2) It was Tom who I met in the park yesterday. 3) It was in the park that I met Tom yesterday. 4) It was yesterday that I met Tom in the park. when It was five o’clock _________I got home. that It was at five o’clock_______ I got home.

强调句用以强调主语,宾语,介词宾语以及状语。(强调 人时用that和who /whom皆可) It was she who /that had been wrong. 是她错了。 ( 主语 ) It was the girl whom /that I met just now. 我刚才遇见的就是这个女孩。 ( 宾语 ) It was Tom to whom the teacher had talked. 老师与其谈话的那个人是汤姆。 (介词宾语) It was on Monday night that all this happened. 所有这一切就是在星期一的晚上发生的。( 状语 )

It is not until + 被强调部分 + that ... 该句型也是强调句型。主要用于强凋时间状语,译成汉语 “直到……才……”,可以说是not ... until ... 的强调形 式。例如: It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses.

六、It 常用的固定搭配
1.make it (1)在口语当中相当于succeed,表示:成功、 做到、说定、赶上、及时到达 例 It's hard to make it to the top in show business. (2)在口语中相当于fix the date for,表示 “约定好时间”例 —Shall we meet next week? —OK. We just make it next Saturday.

2. take it/things easy 相当于Don‘t worry or don’t hurry. 用来劝告别人, 表示“不要慌,别担心,沉住气” Take it easy! He will do it well. 3. It all depends/that all depends 在口语中,相当 于it hasn‘t been decided yet,表示“那得看情况, 还没有定下来” —Are you going to the countryside for holiday? —It/That all depends. 4. It's up to sb. 在口语中,相当于it's decided by sb. 表示“由……决 定,由……负责,取决于……” —Shall we go out for dinner? —It's up to you.
