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。

　　e.g. 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。

　　e.g. 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?

　　e.g. When and where was it that you were born?

　　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 + 其他部分

　　e.g. 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.

　　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 sit down. 务必请坐。

　　He did write to you last week. 上周他确实给你写了信。

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