That is_____he said.A.all what B.all which C.all that D.all what 为什么选C啊

问题描述:

That is_____he said.A.all what B.all which C.all that D.all what 为什么选C啊

这里只能选C,因为主语That要求 ,只能把这个归为惯用法

因为all是介词,all that就相当于what

介宾短语啊,That is 后面需要的是名词或名词词组.
A不对,不需要加ALL,直接是what he said 就可以了
B不对,一看就知道,which是哪个
D不对,因为和A是一样的.
what he said 就是个名词短语了.

ALL THAT=WHAT
所以答案是:that is what (all that)he said.
all that (what) 引导宾语从句
