第九节强调句
这里讲的强调句主要是以it为引导词的分裂句。

它的结构形式是：It+be的一定形式+被强调成分+ that-／who- 分句(只有当被强调成分是句子的人称主语时，连接词才可以用who，此时也可以用that：其余情况下只能用that)。

通过这种结构可以强调除谓语动词外的大多数句子成分。

例如：
1.It was Mary that／who needed the cash．
2.It was the cash that Mary needed．
3.It was from Henry that John bought the car．
4.It was the car that John bought from Henry．
此结构可以强调多种多样的状语成分，例如强调时间状语、地点状语、方式状语，也可以强调由because引导的原因状语分句，但不可以强调由since／as引导的原因状语分句，也不可以强调由although和whereas引导的从属或并列分句。

例如：
1.It was before liberation that our people suffered from the imperialist aggression．
2.It is in Iran that the family members participate in the wedding preparations．
3.It was because he'd never had the opportunity that John hadn't learned to drive．
如果要强调谓语动词，通常采用另一种句型：主语通常是由what 引导的名词性分句；分句的主动词通常是do的一定形式；主语补语通常是不定式结构，可带to，也可不带to。

例如：
The pupils elected him monitor of the class。

强调谓语动词elected，变为：
What the pupils did was elect／to elect him monitor of the class．。
