1. 陈述句的强调句型 It is/ was + 被强调部分+ that/ who（当强调主语且主语指人）+ 其他部分。 　　 It was yesterday that he met Li Ping. 1: It was my father that did the experiment in the lab yesterday evening． 强调宾语：It was the experiment that my father did in the lab yesterday evening． 强调时间：It was yesterday evening that my father did the experiment in the lab． 强调地点：It was in the lab that my father did the experiment yesterday evening． 2. 一般疑问句的强调句型 同上，只是把is/ was提到it前面。 It was yesterday that he met Li Ping. Was it yesterday that he met Li Ping? 3. 特殊疑问句的强调句型 被强调部分（Wh-）+ is/ was + it + that/ who + 其他部分？ 　　 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. 　　 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 　　 务必请坐。 Do sit down. 过马路时，务必（千万）要小心啊！ 　 Do be careful when you cross the street.　　 B. 注意：此种强调只用do/ does和did，后面的谓语动词用原形。 （6）可以强调以not…until…引导的时间状语 我们用“It was（is）not until+被强调的部分+that+原句剩余部分”句型表示“是直到……才……”。如： He and the other doctors did not leave until the operation was over. 他和其他医生等手术做完后才离开。 = It was not until the operation was over that he and the other doctors left. 注：在强调句型中只用until，不用till，由于that前已有否定词not，故that后的句子要用肯定式。如： Thank you for listening * By Tan Xia From NO.40 School of Gui Yang Unit4 Global warming Emphasis My father did the experiment in the lab yesterday evening． 三、强调句型7注意 1. 句首词用“It”，不能用“This”，“That”等。 2. be动词总用单数形式，即is或was，不能用复数形式are或were。 3. 被强调的部分如果是代词，强调主语用主格，强调宾语用宾格。如： （3）It is him that (who/ whom) I met in the street yesterday. （4）It is I who am wrong. 4. 连接词一般用that，当强调部分是人时，强调主语也可用who，强调宾语也可用whom或who。 特别注意当强调部分是时间状语或地点状语时，不能用when或where。 如: 5）It was on Oct. 1st, 1949 that People’s Republic of China was founded. 5. 其他部分中的主谓一致问题。 若强调部分是句子的主语，强调部分是单数，谓语动词用单数形式；若强调部分是复数，则谓语动词用复数形式。如： （6）It is Mary who
