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。

高考英语it用法
高考英语it用法在高考英语中，“it”的用法是一个重要且常考的知识点。
掌握“it”的各种用法，对于提高英语成绩和语言理解能力有着至关重要的作用。
首先，“it”可以用作人称代词，指代前文提到过的事物或情况。
比如：“I bought a book yesterday It is very interesting”在这个句子中，“it”指代的就是前面提到的“book”。
“it”还常被用作非人称代词，表示天气、时间、距离、温度等。
例如，“It's sunny today”（天气）“It's five o'clock”（时间）“It's a long way from here to the station”（距离）“It's very cold”（温度）在强调句中，“it”的作用也十分突出。
强调句的基本结构是：“Itis/was ＋被强调部分＋ that/who ＋句子其他部分”。
通过这种结构，可以强调句子中的主语、宾语、状语等成分。
比如：“It was Tom who broke the window”强调的是主语“Tom”；“It was yesterday that I met him”强调的是时间状语“yesterday”。
“it”作形式主语也是高考中的常见考点。
当句子的主语过长，为了避免头重脚轻，通常会用“it”作形式主语，而把真正的主语后置。
常见的句型有：“It is ＋ adj ＋（for/of sb）to do sth”，例如：“It is important for us to learn English well” 还有“It takes sb some time to do sth”，像“It took me two hours to finish my homework”“it”作形式宾语的情况也不少见。
常见的结构为“find/think/consider/make ＋ it ＋ adj／n ＋to do/doing/that”，例如：“I find it difficult to learn math” 这里“it”代替了后面的“to learn math”，使句子结构更加平衡。

5. It takes sb. ... to do sth. “做...要花费某人...” 成千上万的人们花了好些年才建好了长城。
It took thousands of people many years to build the Great Wall.
6. It doesn’t matter whether ( if ) ...
It is necessary that he (should) remember these words.
13. It is suggested/ordered /demanded/insisted/ commanded...+that 从句(should) do sth. 人们建议会议推迟。
