强调句一直是近几年高考命题的热点，由于该句型极易和定语从句主语从句等放在一起考查且繁杂多变，常使同学们望而却步。现将该句型整理总结如下，以期对同学们有所帮助。
1 强调句的基本结构
强调句的基本结构为：It is (was) +被强调部分+that(who)+句子的其它成份。
2 运用强调句应注意的几个问题
1)强调句可用来强调除谓语之外的其他句子成分。其中的it本身没有词义。
2)强调句中的连接词一般只用who（指人）或that(可指物，也可指人），若被强调的是状语，也只能用that,而不能用when或者where.而且连接词都不能省。如：
It was at 8 o’clock that he arrived at the airport .
3)在使用过程中应注意that/who之后的谓语动词的人称和数要与它前面被强调的名词或代词一致。如：
It is I that /who am your friend .
4)强调句型的时态常见的有两种：一般现在时和一般过去时。
5)注意强调句和定语从句的区别：方法是如果将句中的It is /was...that/who...去掉，经整理后还是一个完整的句子，本句就是强调句。否则，就不是。如：
It was on the streetthat we found the dog .去掉It was...that之后，句子可以整理为：We found the dog onthe street . 这是一个完整的句子，故本句是强调句。再如：
It was 8 o’clock when we met at the bus stop .去掉It was...that之后，句子不成立，此句为定语从句。
6)强调句的一般疑问句和特殊疑问句分别为：Is/Wasit +被强调的部分+that/who ...?和疑问词（when /where /what/ how...）+is/wasit that+ ...?
7)在not ...until ...的句式中，其强调句的形式为：It is /was not until ...that ...如：It was not until dark that I realized that it was too late to go home .(原句应为：I didn’t realize that it was toolate to go home until dark .)
8)强调句和以it开头的状语从句的区别,试比较下列各句：
如:It was two years ago that I first met her .(强调句）
It is two years since I first met her .（由since引导的状语从句）
It will not be long before he returns home .(句型It won’t be long before +clause表示“不久就...”)
9)特别注意的是，该句型用来强调原因状语从句时，原因状语从句的引导词只能用because而不能用since ,for ,as 等。如：It was because it snowed heavily last night that I didn’t come to the evening party held in my aunt’s.
巩固练习：
1. It isthat I met on the street yesterday .
A. she B. hers C. her D. he
2. It will be two years he gets his degree .
A. when B. that C. before D. which
3. It is the ability to do the job matters not where you come from or what you are .

9. In America , it is often the judges ,rather than the politicians, make the big decisionwill change people’s daily life .

10. is a fact that English is being accepted as an international language .
