题目内容：

To be a doctor is___ I ever wanted to be A:all that B:all what C:that
这道题应该选择什么?如果选择 all that 的话 that 是否可以省略

优质解答

A:all that
严格来说,这句话有错.
To be a doctor is all (that ) I want to do .
To be a doctor is what I want to do .
成为医生,就是我想要做的.
A doctor is what I want to be .
A doctor is all (that ) I want to be .
医生,就是我想要成为的.
一个是定语从句,一个是主语从句,括号内可省.
