强调句型的基本结构：It is/was＋被强调部分＋that＋其他。当被强调部分指人时，可以用who代替that。该句型可强调主语、宾语、状语等，但不能强调谓语。

→It was my grandpa that/who walked the dog in the street yesterday.（强调主语）
→It was yesterday that my grandpa walked the dog in the street.（强调时间状语）
→It was in the street that my grandpa walked the dog yesterday.（强调地点状语）
（导学案P57）
名师点拨
使用强调句型时需要注意以下三点：
（1）强调句型中的it不能用其他词代替。
（2）用is还是was要根据原句的时态而定：属于现在或将来时间范畴的所有时态用is；属于过去时间范畴的所有时态用was。
（3）判断句子是否为强调句型的方法：去掉句子里的it is/was与that/who，剩余部分若结构完整、句意明确，则为强调句型，否则就不是。

I didn’t realize all my mistakes until you told me yesterday.
（1） _______________________________________________________________________（对主语进行强调）
It was I that/who didn’t realize all my mistakes until you told me yesterday.

（对宾语进行强调）
