楼主是指强调句型吧?
1.基本结构：
It is/was + 句子被强调部分 + who/whom/that + 句子其他未被强调部分.
如果句子被强调部分为人时,中间的引导词可以用who/whom,也可以用that.
强调句子任意成分（谓语动词除外）,引导词都可以用that.
2.最大特点：
去掉it is/was和引导词who/whom/that后,剩下部分能够构成一个完整的句子（有时候需要调整句序）.
如：I met him in the street yesterday.
如果强调主语I,则强调句型为：It was I who/that met him in the street yesterday.
如果强调宾语him,则强调句型为：It was him whom/that I met in the street yesterday.
如果强调地点状语in the street,则强调句型为：It was in the street that I met him yesterday.
如果强调时间状语yesterday,则强调句型为：It was yesterday that I met him in the street.
