强调句

　　(一)强调句句型

　　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)+ 其它部分。

　　e.g. It is in the year of 1949 that People’s Republic of China was founded.

　　2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。

　　e.g. Is it in the year of 1949 that People’s Republic of China was founded.?

　　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 + 其它部分？

　　e.g. When and where was it that you found the book?

　　4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。

　　强调主语：It was I that (who) met Li Ming at the railway station yesterday.

　　强调宾语：It was Li Ming that I met at the railway station yesterday.

　　强调地点状语：It was at the railway station that I met Li Ming yesterday.

　　强调时间状语：It was yesterday that I met Li Ming at the railway station.

　　5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。

　　(二)not … until … 句型的强调句

　　1、句型为：It is/ was not until + 被强调部分 + that + 其它部分

　　e.g. 普通句：He didn’t go to bed until/ till he finished his homework.

　　强调句：It was not until he finished his homework that he went to bed.

　　2、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。

　　(三)谓语动词的强调

　　1、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。

　　e.g. Do hand in your homework today. 务必今天交作业。

　　He did call you yesterday. 昨天他确实给你打电话了。

　　Do be careful when you cross the street. 过马路时，务必(千万)要小心啊！

　　2、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。
