I don`t understand all that what he said mean.为什么能这么说1) I don`t understand all that what he said mean.2) I don`t understand all what he said mean.3) I don`t understand what what he said mean.我只觉得第三个对

问题描述:

I don`t understand all that what he said mean.为什么能这么说
1) I don`t understand all that what he said mean.
2) I don`t understand all what he said mean.
3) I don`t understand what what he said mean.
我只觉得第三个对

仅仅第2个对。

此句是宾语从句

三个句子都为宾语从句.但mean 是及物的,也要跟宾语.
首先说第三个吧understand 后面的是understand的宾语.第一个what 做mean的宾语,正确.
1)和2)是一样的,宾语从句的that 可以省略.all是mean 的宾语.正确
