Step1. Warm-up & Lead-in
研究一下近年来的高考试卷可以发现，含 it 的句型几乎年年考到。核心考点：强调句型；it用作形式主语或宾语；固定搭配。现根据其用法特点归纳出下面的24个it常用句型。
Step2. Explanation & Comparison
1. It is/was + 被强调部分 + that ….
该句型是强调句型。将被强调的部分放在前面，其它部分置于that 之后。被强调部分可以是主语、宾语、表语或状语。强调的主语如果是人，that 可以由 who 换用。
e.g.
It was they that (who ) cleaned the classroom yesterday.
It was on Thursday afternoon that he told me about the truth.
It was in the street that I came across one of my friends the other day.
2. It is/was not until + 被强调部分 + that ...
该句型也是强调句型。主要用于强凋时间状语，译成汉语 “直到……才……”，可以说是 not ... until ... 的强调形式。
e.g.
It was not until she took off her dark glasses that I realized she was a famous film star.
= Not until she took off her dark glasses did I realize she was a famous film star.
= I didn't realize she was a famous film star until she took off her dark glasses.
