主语从句

情况1:

John很矮是总所周知的。

John is short is public knowledge. 这就错了,因为有两个谓语动词。

从句需要一个词来引导。

That John is short is public knowledge .(有点拗口却完全正确)

英语一般不喜欢头重脚轻。所以可以变换一下,加一个形式主语。

It is public knowledge that John is short.

这样就非常常用了。

因此其实是两种形式,后面一种形式更加常用。

That the seas are overfished has been known for years.

It has been known for years that the seas are overfished.
