注意： (1)从句作主语谓语动词常用单数，但如果 what 引导的从句作主语，后跟名词作表语 时，谓语动词则由表语名词的数量决定。 What he told me is true. 他告诉我的是真的。 What he saw were some new comers. 他看见的是些新来的人。
(2)It is said that sb.do sth.的复合句形式可转化为简单句sb.be said to do sth.， 而且在简单句中常考查 to do 的具体形式。 (3)it 引导的强调句与 it 作形式主语的复合句的区别。 it 引导的强调句是用来对句中除谓语外某一成分加以强调，其结构为“It is/was＋ 被强调部分＋that/who...”。如果被强调的主语是“人”，则可用 who 或 that， 如果被强调的部分是其他成分时，必须用 that。 It was I that/who met John in the street yesterday. 是我昨天在街上遇到了约翰。(强调主语) It is a pity that you didn't go to see the film. 你没去看电影很可惜.ppt
演讲人

(三) if/wheter 在主语从句中的用法
If the meeting will be put off has not been decided yet.
Whether the meeting will be put off has not been decided yet.
注意：whether 可以引导主语从句可以放在句首， 但if不能
宾语从句

That they like each other is natural. 正确
It is natural that they like each other. 正确
That引导的主语从句放句首，既不充当成分又无意义， 但that不能省去。

Whoever breaks the law will be punished.
主语从句能用it做形式上的主语(二)
注意: 由that 引导的主语从句有时为了使句子结构平衡, 避免 “头重脚轻”, 常用 it 作形式主语, 而把从句放在
后面。 例如:*it为形式主语
