it强调句型

it 引导的强调句型，通常形式为：It be 被强调部分 that/who 句子其他成分。这种强调句由普通陈述句转换而来，用来强调句子的主语、宾语或状语。例如：

It was Tom's mother that / who bought Tom a bicycle on his birthday.

是汤姆的妈妈在汤姆生日那天给他买了辆自行车。

It was yesterday that I met him. 我是昨天见到他的。

在此类强调句中需要注意的是：

1)不管被强调部分是单数还是复数，其前一律用it is / was 而不能用 they are /were

It is the teachers who teach me very well. 这就是教我教得很好的老师。

2)被强调部分指人时，被强调部分可用that /who来指代；被强调部分指物时，被强调部分后只能用that 指代
