英语中的强调句型是高考的常考点也是易错点，很多同学不知道如何去把握。其实强调句型的学习也可以变得很简单，下面就让我们一起通过分析五句话来搞定强调句型吧。
Sentence 1:
It was about 20 years ago that Joe got married.
[中文翻译]正是在大约20年前Joe成了家。
[学习笔记]在肯定句中，强调句型的结构为：It is/was+被强调部分+that引导的从句（如果被强调部分是人，也可用who代替that）。被强调的部分通常是句子的主语、宾语或状语，这种句型不能强调谓语或定语。
注意：强调谓语用do的各种形式+动词原形
如：I do love you. 我是真的爱你。
I did love you. 我确实曾经爱过你。
He does hate her. 他确实恨她。
Sentence 2:
Was it you that I saw last night in the cinema?
[中文翻译]昨天在电影院我看到的确实是你吗？
[学习笔记]在一般疑问句中，强调句的结构为：Is/Was it+被强调部分+that/who。
Sentence 3:
Who was it that broke the window yesterday?
[中文翻译]到底是谁昨天打破了窗户？
[学习笔记]在特殊疑问句中，强调句的结构为：被强调部分（由疑问代词或疑问副词充当）+is/was+it+that/who。
Sentence 4:
It was not until she took off her dark glasses that I realized she was a famous film star.
[中文翻译]直到她摘下深色眼镜我才意识到她是一位著名的电影明星。
[学习笔记]记住固定用法：It is/was not until+时间+that…，“正是直到……才……”。
Sentence 5:
(1)It might be Joe that you are thinking of.
(2)It must have been his sister that you saw.
[中文翻译]
（1）你所关心的可能正是Joe吧；
（2）你看到的想必是他的姐妹。

(1)It might be … that …
(2)It must have been … that …
