------ is known to us all is that the 2008 olympic games will take part in beijing.
a, as
b,which
c,what
d,it
选what
“what is known to us all” 构成一个名词性的短语,做主语,谓语is...
如果选as,句子应当是As is known to all,the 2008....这样才对
如果选it,句子应当是It is known to all that the 2008....谓语是第一个is,不需要第二个
which肯定不对...
a
..高中固定语法,as is known to all.背下来
众所周知
选d,
it isj加形容词to sb 对于某人来说怎么样
a不符合句意
b,c,是疑问词,可后面没问号
