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。
