高中英语语法之强调句及练习题
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!
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。
