it在强调句中的使用

先看看这道题：

__________ these boys that played tricks on their teachers.

A. They were                        B. It were                        C. There were                        D. It was

【分析】此题应D。这是一个强调句型，其基本结构为：

It is＋被强调部分＋that(who)＋其他

该句型应注意以下几点：

1. 不管被强调部分是单数还是复数，其前一律用It is / It was，而不能用They are / There were之类的。

2. 被强调部分是指人时，被强调部分后可用that / who，被强调部分指物时，被强调部分后只能用that。

3. 被强调部分是指时间或地点时，被强调部分后通常用that，一般不用when，where之类的。

It is I who am right. 是我对。

It was you that were wrong. 是你错了。

It was in the Japan that he died. 他是死于日本。

It was yesterday that he got married. 他是昨天结婚的。

It was a computer that he bought last week. 他上个星期买的是一台电脑。

Where was it that she lived? 她是住在什么地方?
