第 1 页 Unit4 Global warming-语法篇 __________________________________________________________________________________ __________________________________________________________________________________ 1. 掌握it在强调句中的用法； 2. 能够利用这个语法点进行遣词造句并运用到写作中； it的用法—强调句型 一、强调句型的基本用法 英语中常用的强调句型是：It is / was + 被强调部分(主语、宾语、状语) + that / who / whom + 其他部分。一般来说，被强调部分指人时，用who或whom，其他情况用that，但that也可指人。 现在用强调句型强调下面这个句子的主语、宾语和状语。 She met John at Mary’s birthday party last Sunday. →It was she who / that met John at Mary’s birthday party last Sunday. (强调主语) →It was John Whom / that she met at Mary’s birthday party last Sunday. (强调宾语) →It was at Mary’s birthday party that she met John last Sunday. (强调地点状语) →It was last Sunday that she met John at Mary’s birthday party. (强调时间状语) 温馨提示： 1.it为引导词，本身没有词义，仅起引导强调句式的作用； 2.若强调的主语是人时，常用who，间或用that，若强调的宾语是人时，多用whom / that； 3.在强调状语时，用that； 4.在强调结构时，无论被强调的是人还是物，是单数还是复数，be动词一律用单数形式is / was, 如果原句中的谓语动词是过去时态，就用was，若是现在时态或将来时态，就用is， 也可用情态动词 + be形式； 5. 判断一个句子是否是强调句型的方法：如果将句中的It is / was… that / who / whom…去掉，仍能还原为一个完整的句子，那么此句就是强调句。否则，就是其他句型结构。 请比较： It was 2019 when he came back from the United States. (定语从句) It was in 2019 that he came back from the United States. (强调句型) 6. 被强调部分若是句子的主语，that / who之后的谓语动词在人称和数上应与句子的主语保持一致。 eg：It is I that / who am your friend that will come to help you. 二、强调句型的几种较为复杂的结构形式 1. 被强调部分为状语从句。 Eg: It was when Tom was eleven years old that his talent for writing became obvious. 2. 被强调部分含有定语从句。 Eg: It was on July 4 th, 1975 when he was born that his father died. 3. not…until结构用于强调句型。 第 2 页

not…until作为被强调部分，起结构是：It is / was + not until…+ that + 其他部分。 Eg: It was not until his father came back that he went to bed. 4. 强调句型的一般疑问句结构：Is / Was it + 被强调部分+ that + 其他部分。 Eg: Was it last year that his cousin joined the army? 5. 强调句型的特殊疑问句结构：疑问词（被强调部分）+ is / was + it + that + 其他部分。 Eg: When was it that the accident happened? Where was it that you lost your wallet? 1. (2019·南通二调)Do you know in what circumstances it was ________Jack achieved his goal? A. that B. how C. where D. when 2.
