下面就其使用的重点及难点,分门别类地加以总结。

1. 作人称代词,可以用来代替人、物或事；亦作非人称代词，表示时间、天气、季节、距离等。

It i s r aining c ats a nd d ogs. 雨下得很大。

It is a long way to the college. 大学距这儿很远。

It is eight o’clock sharp now. 现在是8点整。

2. 指无生命的东西，性别不详或性别无关紧要时，可用“It”来指动物，幼童等。

The baby cried because it was hungry。

小宝贝因为饿而哭了。

3. 作形式主语英语中不定式、动名词、主语从句在作主语时，主语往往显得很长，使整个句子看上去有点头重脚轻，这时就需要借助“It”作形式上的主语，而把整个句子的主语移到句子后边去，使句子看上去平稳一些。

It is difficult to study and work at the same time.一边工作一边学习很难。

It is very clear that the elephant's l eg is round a nd tall like a tree.大象的腿跟树干一样圆而高，这点显而易见。

高考英语语法It所构成的20个句型详解

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。
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。
It was not until she took off her dark glasses that I realized she was a famous film star.
It is time that children should go to bed. = It is time that children went to bed.
9. It is the first （ second … ） time that …
该句型要和上一个句型区别开来。该句型中的 that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中 that 可以省去；it有时用 this 替换。常译为”是第一（二）…次…“。

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 her e．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 fora while。

23）It is strange that he did not come at all.真奇怪，他竟还没来。

24）It doesn't matter what you do.什么都没关系。

在上述诸例中，后置的真正主语可以取代先行it的位置，而出现于句首。

To translate this article is difficult.Going there so early is no use.That he did not come at all is strange.上述结构远不如用先行it 结构普通。

此外，也并非所有先行it结构都可作上述转换。

如：25）It seems that John is not coming after all.似乎约翰终竟不来。

26）It happened that John was the only witness.碰巧约翰是唯一的证人。

上述两例只能转换为：John doesn't seem to be coming after all.John happened to be the only witness.（2）用作形式宾语27）I found it difficult to explain to him what happened.我觉得向他解释清发生了什么事很困难。
