It可替代后面的不定式、动名词、主语从句等。
该用法通常用于一下句型：1.”It is +adj./n./v+ing./p.p.+ that….”.适用于这个句型的动词有say, announce, decide, learn, know, report, hope, believe, expect, suggest等。
适用于此句型的名词有idea, belief, dream, pity, wish, fact, wonder, problem, pleasure等。

Eg.

It appears to me that he is fond of collecting stamps.据我所知，他好像喜欢集邮三．用作形式宾语1.当动词不定式、动名词、或从句在句中充当宾语且其后带有宾补时，习惯上要在宾补前使用一个没有具体意义的形宾it，而将真正的宾语移到补足语的后面，构成“V. + it + OC+to do/v +ing/从句(常将该句型称之为6123结构)Eg. I think it no good going there now.The headmaster has made it clear that the meeting will not be put off.6123结构：6指主句中6个常用的动词，即think, believe, make, find, consider, feel;1指的是形宾it2指的是宾补的两种形式——形容词和名词（短语）3指的是真正的宾语的三种形式——不定式短语、动名词短语和that引导的宾语从句。
2. It作形宾时其后没有adj. 或n.作宾补的情况（近几年高考常涉及）Eg. I hate it when people talk with their mouths full.I’d appreciate it very much if you would help me with it.该用法中的动词经常是表示“喜怒哀乐”的动词。
如：enjoy, like, dislike, love, hate, prefer, appreciate等四．It构成的强调句型强调句型“it is/was + 被强调的部分+that/who + 其他成分”用来强调主语、宾语或状语等。
That 只起连接作用，不作成分，但不能省略。
有时强调的部分比较特殊，如主从、状从、名词、不定式、动词-ing的复合结构。
Eg. It was in the library that I saw her yesterday.It was when I returned that she left the meeting room.注意：1.要注意it 所构成的强调句型和它代表时间、距离、温度、自然现象、具体事物或人物等构成的各种句型的区别。
如: It was on March 1 that I had my hair cut.It was March 1 when I had my hair cut.2.采用“还原法”来判断强调句型3.强调句型的三种形式：A: 一般疑问句形式：Was/Is it + 强调部分+ that/who +其他成分B:特殊疑问句形式：特殊疑问词+is/was+ it +that/who +其他成分C: not….until…的强调句形式：It is/was not until +被强调成分+that+其他成分五．It 常用固定句型1．It takes sb…..to do sth (=Sb takes….to do sth)2.
