it看似很简单，却在历年高考中频繁出现，形式多样，就该词的各种用法总结如下，希望能对学生们尤其是高三的同学们有所帮助。

一、it的指代作用

It通常可以代替时间，天气，距离等，这类考题很容易，不再论述，关键是it的指代作用时与one， ones， that ，those所指代内容的区别：one用来代替单数可数名词，泛指；ones用来代替复数可数名词，泛指；that用来代替单数可数名词或不可数名词，后面有后置定语修饰；those用来代替复数可数名词，特指，相当于the +ones； it用来代替单数可数名词， 特指.试看下列试题：

1. （07陕西）―There is still a copy of the book in the library . Will you go and borrow ？

―― No， I’d rather buy in the bookstore.（07陕西）

A. it， one B. one， one C. one， it D. it， it

解析：第一空特指a copy of the book，第二空泛指书店里的书本，故选A。

2.（09全国） One of the most important questions they had to consider was of public health.

A. what B. this C. that D. which

解析：后置定语，故选C。

3.（2011福建）We have various summer camps for your holidays. You can choose ____based on your own interests.

A. either B. each C. one D. it

解析：泛指，故选C。

二、It is/was用于强调句中

It is/was +被强调部分+that…或特殊疑问词+ is/was+ it+that+其它？看下列高考题：

1.（08重庆）It was not until midnightthey reached the campsite.

A. that B. when C. while D. as

解析：not until连在一起，空后面是陈述句，故选A，此句是not until的强调句型。

2.（06山东）I just wonder that makes him so excited.

A. why it does B. what he does

C. how it is D. what it is

解析：wonder后接宾语从句缺主语，故用what，又是强调句，加上宾语从句用陈述句型，故选D。

3.――Where did you find her？

――It was in the factory we worked.

A. that B. where C. which D. where

解析：此题易误选A，实际上此空它是定语从句，缺状语用where，此题完整形式是：It was in the factory where we worked that I found her.再看两例：

4.It was at 5 o’clock he came here.

A. that B. which C. when D. where

5.It was 5 o’clock he came here.

A.that B. which C. when D. where

解析：第4题强调时间状语，故选A，第5题5 o’clock前没有介词，是时间状语从句，故选C。顺便看一下下列固定句型： It ishas been +时间段+since …

It will be/was +时间段+before …

6.It is 6 years I began to learn English.

A. that B. before C. since D. when

7.It will be four years we meet again.

A. that B. before C. since D. when

解析：记住这两个固定句型，很容易找到答案，故第6题选C，第7题选B。

三、it用作形式主语和形式宾语

1.（2012江西）It suddenly occurred to him_____he had left his keys in the office.

A. whether B. where C. which D. that

解析：此空是形式主语，真正主语是he had left his keys in the office，故选D。

2.（2011山东）The two girls are so alike that strangers find ____difficult to tell one from the other.

A. it B. them C. her D. that

解析：此空是形式宾语，真正宾语是to tell one from the other ，故选A。

下面各自总结一下用作形式主语和形式宾语的句型。
