核心问题
What have I done that you should insult me? 请问 that 从句是 what 的定语从句吗?
词典解答
that引导的是一个结果状语从句，而不是定语从句，它永远位于what疑问句之后。上面句子的意思是：
我到底做了什么事,竟使得你来侮辱我?
类例：
-
What was the matter with the fellow that he looks so happy? (Galsworthy) 这小伙子发生了什么事,显得这么高兴?
-
What has happened that all of them look so excited? 到底发生了什么事使他们大家显得那样激动？
what . . . that
- What have I done that you should be so angry with me? 我到底做了什么事,惹得你对我这么生气?
