-强调句型例句：我们昨天在班会上选举他为班长。Eg: We elected him monitor at the class meeting yesterday.主 宾 宾补 地状 时状 Lead-in强调句型是英语中的一种重要的句子结构， 它可以强调除谓语以外的其它成分，是英语学习 者必须掌握的一种重点句型，因而在高考英语试 卷上占有一席之地。现对强调句型的各个主要方 面作以归纳。 It was we that /who elected him monitor at the class meeting yesterday. （强调主语）It was him that /whom we elected monitor at the class meeting yesterday. （强调宾语）It was monitor that we elected him at the class meeting yesterday. （强调宾补）It was at the class meeting that we elected him monitor yesterday. （强调地点状语）一，基本结构：It is(was)+ 被强调部分+ that（强调部分是人时也可用 who/whom） +其他成分Eg: We elected him monitor at the class meeting yesterday.主 宾 宾补 地状 时状二、强调句型的判断把“It, be，that”去掉，如果剩余部分句子结构仍然完整 （被强调部分要还原到原位置），那么这个句子就是强调 句；如果句子不完整，则不是强调句。如： （1）It is he who / that often helps me with my English. It is on the hillside that we plant trees every year. It was because of bad weather that the football match had to be put off.(Shanghai 2003, spring)分析：去掉It is / was. that / who 句子后结构仍然完整， 句意仍明确，都是强调句。 It was 9 oclock when we came back 我们回来时是九点钟。 It was 3 hours since we had come back我们回来已三个小时了。 分析： 在上面例句中若去掉It was. when / before / since 等后，句子结构就不完整，所以不是强调句。2） It was at the theatre _ Lincoln was murdered.It was the theatre _ Lincoln was murdered.A. which B. that C. whereD. the oneCB It was our teacher _did the experiment in the lab last night. A.whom B. that C. which D. where It was ten years ago_ Miss Gao returned to China.

It was not until it stopped that we got off the bus.(注意：强调该结构时not until不能分开) (14)It was not until 1920_ regular radio broadcast began. (NMET95) A. while B. which C. that D. since(C)(15)It was not _ she took off her dark glasses _ I realized she was a famous film star. 1992A. when; thatB. until; thatC .until; whenD. when; thenB(16) It was _ back home after the experiment. A. not until midnight did he go B. until midnight that he didnt go C. not until midnight that he went D. until midnight when he didnt go C（17） It was not until _ that _ to prepare his lessons.(Shanghai91)A. did his father come in; the boy beganB. his father came in; the boy beganC. did his father come in; did the boy beginD. his father came in did the boy begin(18)Not until_ _ to prepare his lessons.B注意: (18)是notuntil 的另一种强调形式：Eg: The villagers didnt realize how serious the pollution was until all the fish died in the river .DIt was not until all the fish died in the river that the villagers realized how serious the pollution was . Not until all the fish died in the river did the villagers realize how serious the pollution was.7. 疑问句的强调结构：一般疑问句：Is / Was + it + that +句子的其他部分（陈述语序 ）。简单的答语为：“Yes,it is/was.”或 “No,it isnt/wasnt.”(19)-Was_that I saw last night at the concert?(Shanghai97)-No, it wasnt.A. it you B. not you C. you D. that yourself(20)-“Wasnt it Dr Wang who spoke to you just now?-_.
