英语强调句特点

第一句是定语从句。第二句是强调句。

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.其他详细用法请楼主参考百度百科相关介绍：如果你满意我的答案，敬请点击 “选为满意回答” ，谢谢！

It is+sb(主格)+wh-疑问词.......

强调句 - 常用句型1. 陈述句的强调句型It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其他部分。例子 It was yesterday that he met Li Ping.2. 一般疑问句的强调句型同上，只是把is/ was提到it前面。例子 Was it yesterday that he met Li Ping?3. 特殊疑问句的强调句型被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其他部分？例子 When and where was it that you were born?4.not … until … 句型的强调句A. 句型为：It is/ was not until + 被强调部分 + that + 其他部分普通句：He didn't go to bed until/ till his wife came back.强调句：It was not until his wife came back that he went to bed.B. 注意：此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not ... 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。5.谓语动词的强调A. It is/ was ... that ... 结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或didDo sit down. 务必请坐。Do be careful when you cross the street. 过马路时，务必（千万）要小心啊！B. 注意：此种强调只用do/ does和did，没有别的形式；过去时用did，后面的谓语动词用原形。【俊狼猎英】 团队为您解答，欢迎追问
