回答1：

A As.由as引导的这一句子成分成为插入语（interjekto）.本来用which也可以，只是witch不能放在句首。It是形式主语，须将逗号换为that，而that可以引导主语从句。此句如果要用that,句子需改为That the earth goes around the sun is known to us all.其实这种说法在一般英美人士重用的不多。

回答2：

A
as引导的是非限制性定语从句，在定语从句中做主语，代替the earth goes around the sun 这一句话
如改一下，选B
It is known to us all that the earth goes around the sun.
It 是形式主语，that引导的是真正主语。
