一道高中英语题目．____ others say, the professor is sure that his theory is correct.A．No matter how B．It doesn’t matterC．Whatever D．What ever为什么不选C...答案选D
1whatever可用作连接词或连接副词,引导让步状语从句,表示“无论,不管”的意思.此时,可用no matter what结构来替换其意完全相同.位置前后置都可以.
2whatever还可以引导名词性从句,同时起先行词和关系代词的作用.相当于anything that或all that,有任何一切这类意思.此时不能用no matter what替换.
3what和ever分开写,则作“到底,究竟”解,这时它和on earth, in the world相同,起强调作用.e.g. What ever do you mean? = What do you mean on earth?

就选c, 你是对的。

C 是形容词，怎么做这个句子的成分啊？ 如果要修饰say，至少也是副词啊
我个人理解这个句子应该是：无论别人说了什么，教授都坚信自己的理论是对的。
