做主语主要分这几种
一、it用作代词
1.指代事物或前面提到过的事物.例如:
——What’s in the picture? 图片里画的是什么?
——It’s a cat. 是一只猫.
It’s the wind shaking the door. 风刮得门响.
2.指人.例如:
——Who is it? 是谁?
——It’s me. 是我.
3.表示时间或季节.例如:

(1) ——What day is today? 今天星期几?
——It is Friday. 今天星期五.
(2) ——What is the date today? 今天几号?
——It’s the third of May. 今天5月3号.
(3) ——What season is it? 现在是什么季节?

4.表示距离.例如:

5.表示气候.例如:

——It’s mine. 是我的.
二、it用作形式主语
it常用来代替不定式、动名词短语或名词性从句作形式主语,位于句首,而被替代的真正主语后置.
1.It+谓语+不定式.例如:
It is easy to climb the hill. 爬那座小山很容易.
It is his duty to settle the problem. 解决那个问题是他的责任.
It is not proper to do so. 这样做不恰当.
2.It+谓语+动名词短语.例如:
It is no use arguing with him. 同他争辩没用.
It is no good going there. 到那里去没有好处.
It is exciting working here with you. 在这里同你一起工作很令人兴奋.
3.It+谓语+名词性从句.例如:
It is clear that she is the best student in the class. 很明显,她是班上最好的学生.
It’s a pity that you can’t go with her. 你不能同她一块去,真遗憾.
It’s certain that he will get on well with them. 可以肯定,他会同他们相处得很好.
It doesn’t matter whether he comes or not. 他来不来都没有关系.
注意：it充当形式主语,构成大量的常用句式.要注意其后不同的谓语形式.
(1) It is a pity that… 真可惜……,可惜的是……
It is a fact that… 事实是……
It is a wonder that… ……这真是个奇迹
It is no wonder that… 难怪……
(2) It is obvious(clear) that… 很明显……,很清楚……

(5) It doesn’t matter… ……是无关紧要的
