是不是所有的主语从句都可以改成It is

Question

如题所述

Answer 1

不是啊，不过是都可以改成 it (做形式主语)，而不是 it is追答

比如：
That he was killed shocked us.
= It shocked us that he was killed.

Answer 2

是不是所有的主语从句都可以改成It is...that呢？
例如：Whether we will go for an outing tomrrow remains unknow.
Who will be our monitor has't been decided yet.
Whom we must study for is a question of great importance.
What caused the accident remains unknown.
Whatever you did is right.
Whose watch was lost is unknown.
以上句子进行IT is...that...的改写：
It is unknown whether we will go for an outing tomorrow.
It hasn't been decided yet who will be our monitor.
It is a question of great importance whom we must stuey for.
It is unknown what caused the accident.
It is right whatever you did.
It is unknown whose watch was lost.
不是所有的都能改成it is...that...
主语从句如果是个问句,那么连词就不能用that,只能用那个问句的疑问词.
