1. It is + 形容词+ that + 主语从句
例如：It is clear that he has made a mistake.
解释：在这个句型中，“it”是形式主语，“that”后的句子是真正的主语。
2. It is + 名词+ that + 主语从句
例如：It is a fact that the earth is round.
解释：这个句型与上一个相似，但形容词被替换为名词。
3. It + 动词+ 主语从句
例如：It happened that he was late for the meeting.
解释：在这个句型中，“it”是形式主语，动词是主语从句的谓语。
4. It + be + 时间/距离+ before + 主语从句
例如：It will be two years before we meet again.

5. It is/was + 被强调部分+ that + 主语从句
