3. 用在强调结构中，其结构为：
It is /was+被强调部分+that/who-clause
1). 可以强调主语、宾语或状语；it 本身没有词义，只用来构成这个句型；指现在用 is, 指过去用 was; that
可以指物，也可以指人，who 只用来指人，偶尔也用 whom 指人（强调宾语时）。
Yesterday he met an old friend in the park.
强调主语： It was he that/who met an old friend in the park yesterday.
强调宾语： It was an old friend that/who he met in the park yesterday.
强调时间状语： It was yesterday that he met an old friend in the park.
强调地点状语： It was in the park that he met an old friend yesterday.
2). 强调句型的基础知识：
①. 强调地点状语不用 where，时间状语不用 when，方式状语不用 how，原因状语不用 why，都要用 that.
It was for this reason that he left that school. (原因状语)
It was in this way that he solved the problem. （方式状语）
②. 也可以是状语从句被强调：
It was only when I reread his poems that I began to appreciate their beauty. （时间状语从句）
It was because she got up late that she didn’t catch the first bus. （原因状语从句）
③. 被强调部分如果是原句的主语，who/that 后的谓语在人称和数上应和原句的主语一致。
It is Mary who often does good deeds.
Ability is what you’re capable of determines what you do.
Attitude determines how well you do it. 2同源学府————用心做教育

It was not I that met your father in the street.
⑤. 判断一个句子是否是强调句的方法：如果将句中的 It is/was…that/who 去掉，经整理后还是一个完整的
句子，本句就是强调句，否则，就不是。
