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did

　　Do 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。
