Question

I'm interested in ( ) you have said

I'm interested in ( ) you have said

A all that
B all what
C that
D which

选哪个，理由是，其他答案为什么错
是选A的，为什么？

Answer 1

A. all作in的宾语，后面that引导定语从句修饰all.
我对你全部都感兴趣，什么全部，后面定语从句that you have said修饰all,你所说的全部
这个句子还可以这样表达，就是把B选项中的all去掉
I'm interested in what you have said.
what充当主句中in的宾语和从句中said的宾语，双重成分，只能由what引导。

Answer 2

all that=what；
what能既做先行词又做引导词，就是因为它可以拆成sth.(随你句子的需要，但是最常用的是all)+that,一个做先行词，一个做引导词

不知你明白了吗？:)
