1、强调句的陈述句形式: It is/ was +被强调部分+ that/ who+其它部分。 注意:被强调部分通常是主语、宾语或状语;强调主语且指人的时候可以用who,其他一律用that。例如: He met an old friend in the park yesterday. 主语谓语宾语地点状语时间状语 对句中各部分进行强调: (1)强调主语: It was he who/that met an old friend in the park yesterday. (2)强调宾语: It was an old friend that he met in the park yesterday. (3)强调地点状语: It was in the park that he met an old friend yesterday. (4)强调时间状语: It was yesterday that he met an old friend in the park. 2、强调句的一般疑问句形式: Is / was it+被强调部分+that/who+其他部分? ①Was it he who/that met an old friend in the park yesterday? ②Was it an old friend that he met in the park yesterday? ③Was it in the park that he met an old friend yesterday? ④Was it yesterday that he met an old friend in the park? 3、强调句的特殊疑问句形式: 特殊疑问词+ is/ was + it + that + 其它部分? ①What is it that you want me to do? ②Who was it that broke the window? ③Where was it that you put your English book? ④When was it that he made up his mind to take this course? ⑤Why is it that he doesn't like the book? ⑥How was it that he got hurt? 注意: (1)强调主语时,谓语动词和主语在人称和数上要保持一致。 ①It is he who/that often does good deeds. ②It is I who/that am looking for you. (2)构成强调句的it本身没有词义;强调句中的连接词只用that或who,即使在强调时间状语和地点状语时也如此,that或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。原句谓语动词是与过去相关的时态,如一般过去时、过去完成时和过去进行时等,用It was …,与现在或将来相关的时态用It is …。 (3)若强调句的疑问句形式放在宾语从句的位置,则需要用陈述句的形式。例如: ①Do
