高考重点：It的用法以及含有it的句型英语中it 一词结构看似简单，但其词义广泛，使用范围很广，常令一些初学者感到头痛。

It用法及其句型和固定搭配，是英语语法的重点、难点，又是近几年考试的热点,在高考中也是重现率较高的语言点，其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。

因此在复习中应给予足够的重视。

下面笔者就it的用法简单归纳如下。

一、代替上文中提到过的人或事物。

指代人时，一般用于小孩或身份不十分明朗的人。

这时的it 不指某个具体的东西。

没有明确的含义。

译成汉语可不必译出来。

如1).It‘s half an hour’s walk from here to our school．从这儿到我们学校是步行一个小时的路程2) It‘s nice and warm here．这里非常暖和3) But it's two o'clock now, and it's time for us to go to school．两点了该是上学的时间了4) It’s quite close in the room . Let’s open the window for a while。

It 构成的20句常用句型归纳【句型1】It is + 被强调部分+ that ...该句型是强调句型。

将被强调的部分放在前面，其它部分置于that之后。

被强调部分可以是主语，宾语，表语或状语。

强调的主语如果是人，that可以由who换用。

如果把这种句型结构划掉后，应该是一个完整无缺的句子。

这也是判断强调句型与其它从句的方法。

【例】It was about 600 years ago that the first clock with a face and an hour hand was made.【例】It was they that (who ) cleaned the classroom yesterday.【例】It was in the street that I met her father.【句型2】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】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.【句型3】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，肯定．．．）＂是主语从句最常见的一种结构。
