十八、强调句 类别 例 句 结构解析 强调句的基本结构 It is I who am a teacher. It is they who often help me with my lessons. It was him that/whom/who they saw stealing yesterday. It was then that he got there. It is at school that he reads English. It was because the water had risen that they could not cross the river. It was what he said at the meeting that made her angry. It was the village where I was brought up that I visited yesterday. (1)It is/was＋被强调部分＋that/who(whom)＋原句剩余部分。 (2)被强调部分可以是句子的主语、宾语或状语，这些成分可能是一个词，一个短语或一个从句，甚至更复杂的结构。 (3)强调句型中的it没有实际意义，由于它处在主语的位置，其后的动词用is/was。不管强调的是什么成分，后面的引导词都可用that，若强调“人”，也可以用who。 (4)这句型的谓语动词也可能有其他时态或带上情态动词。例如： It will be Bill who speaks first. It must have been Jack that forgot to lock the door. It may be this sense of humor that makes him popular. 类别 例 句 结构解析 强调句的基本结构 It was not until midnight that they came back.
