1._____ is known to us all is that hte 2008 olympic Games will take place in Beijing.
A,it B.what C. as D which
答案是B，我选的C，觉得固定搭配绝对没错。。。as is known to us.
A也觉得对，觉得做形式主语，B感觉也没错，真伤脑筋。。。请高手指点迷津

应该选B；
如果是C,就应该这么说：As is known to us all that the 2008 Olympic Games will take place in Beijing.
用it的话就有同样的语法错误。
如果不懂为什么用what可以参照下面这个简单点的句子：What is known is that he's clever.

选B，注意文中有is that,说明前面缺主语，此句是what引导的主语从句。
