强调句 It is … that …
用 It is/was … that … 强调句子的某一个成分。
It is Tom who/that broke the window.
要点
- 可以强调主语、宾语、状语，不能强调谓语。
- 强调人时可以用 who / whom，其余一律用 that。
- 去掉 It is … that 之后句子仍然成立，这是判断依据。
- 时态用 is 或 was，被强调的部分放在中间。
- 强调时间地点时仍然用 that，不用 when / where。
- 老要点第一条说 It is … that 不能强调谓语 —— 真要强调谓语就借 do ／ does ／ did：She did tell me the truth.（她确实告诉过我）
- 强调 not … until 那一块时，not until 要整个搬进框里：It was not until midnight that he came back. —— 只搬 midnight 就把句子的否定丢了。
- 被强调的是一块带介词的状语，介词要连着后面那块一起挪进框：It was with his teacher's help that he worked it out. —— 拆成 It was his teacher's help that… 就把介词丢了。
例句
It is Tom who broke the window.
是汤姆打破了窗户。
It was yesterday that I met him.
我是昨天遇见他的。
It is English that I like best.
我最喜欢的是英语。
It was in the park that we met.
我们是在公园里遇见的。
It was only after the film ended that we got the news.
我们是在电影散场之后才得到那个消息的。
He did finish the report, though nobody believed him.
报告他确实写完了，虽然没人相信。
易错提示
- 判据：把 It is/was 与 that 去掉，句子还成立就是强调句。
- 强调时间地点仍然用 that，不要换成 when / where。
- do 那一套强调只用在一般式的现在或过去：说 did tell，进行与完成时里不叠 do（不说 does be telling ／ did have finished）。
- 回答问句时能把问里的信息整块搬进框：— When did he leave? — It was after lunch that he left. —— 口语里也常只说 After lunch.，两句都对，框只是把话押在那个信息上。
