A.it B.As C.That D.what
四题应选什么,为什么?
关键是为什么

第一题填It.
that Taiwan is part of china是真正的主语.这句本来是：
That Taiwan is part of china is known to us all.
由于主语太长,于是移到句尾,而原先主语的位置空出来了,就用形式主语it来补上去.句子就变成：
It is known to us all that Taiwan is part of china.
第二题填What.
这是一个“主+系+表”结构的句子：What is known to us all是主语；is是系动词；that Taiwan is part of china是表语.
主语中心词是what,what相当于the thing that.
the thing that is known to us all中,that is known to us all是定语从句,修饰the thing.把它浓缩成What is known to us all后就不能再说is known to us all是定语从句了,只能说它是一个名词性短语.

----is well known to us all that Taiwan belongs to China.--- That is known to all,Taiwan belongs to China.改错 Taiwan belongs to China,（）is known to us.为啥不能用that~ --- is known to us all ,Taiwan is part of china It is well known to us all that in china traffic the right It is known to all that the island belongs to China for___(c Taiwan, that is known, belongs to our country怎么改错?只有一处错误改错:Everyone of us knows,Taiwan belongs to China. （What) is known to us all is that China is a developing coun 1.___ is known to us all is that China is a developing count Taiwan belongs to China,that is everybody knows这句话对吗why?
