高考重点：It的用法以及含有it的句型
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。
1) －Who is the baby? －It‘s my teacher’s son．2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you．不定代词one 指代前文提到的同类事物之一，而it 特指上文中提到的同一事物。
试对比：This pair of shoes is small. May I have another one？（泛指的另一双）这又鞋子太小了，再拿一双给我看看好吗My pen is missing.Ican’td find it.我的钢笔丢了找不到了(it指my pen)二. it 作为无人称动词的主语，表示天气，时间，距离，环境情况等等。
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常用句型大盘点
It常用句型大盘点“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，因此在复习中应给予足够的重视。
现将it用法归纳如下：1. It is + 被强调部分+ that ...【说明】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可以换成who。
如果把这种句型结构It is / was... that /who... 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。
【举例】It was I who / that met Jim in the street.(强调主语)It was in the street that I met Jim. (强调状语)It was Jim who / that I met in the street. (强调宾语)It is a chief engineer that he becomes now. 他现在担任的是总工程师（强调表语）2. It is not until + 被强调部分+ that ...【说明】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。
【举例】It was not until I got home that my mother went to bed.= M y mother didn’t go to bed until I got home.=Not until I got home did my mother go to bed.3. It’s no use / good doing sth. 做某事没有用。
【举例】I t’s no use/good crying over spilt milk.= Crying over spilt milk is no use / good.4. It’s a waste of time doing sth. 浪费时间做某事。
