2.主语从句的考点和难点

(2)陈述语序

例句： Whether it will do good to us remains to be seen.

How the accident happened is still unknown.

Who won the game hasn't been announced yet.

(3)时态搭配(it = 形式主语)

用it做形式主义的目的：避免主语过长，导致整个句子头重脚轻

例句： It surprises us all (that) he will come to our village tomorrow.

[考点]：<1>以what / whatever引导的主语从句不可以改为 it 形式主语的结构；除了做连接词外，what/ whatever还会做从句中的成分，比如主语 / 宾语。(所以不可以改为 it 形式主语的结构)

<2> It is + 形容词 / 名词 / 名词性短语等 + 主语从句

（表示重要/必要的词/词组，如 Important necessary A necessity）

that从句中的谓语动词一般要采用‘’should + do‘’的虚拟语气形式，should的经常省略

例句： It is necessary that we (should) learn English well.

It is highly important that we (should) fasten the belt while driving the car.
