题目

whoever 和no matter who在用法上的区别是什么?
如题

答案

whoever 和no matter who 都是无论谁,不管谁的意思.
但whoever可以作为引导让步状语从句的连接代词,而no matter who 不能.
whoever和no matter who 是疑问词 + ever和no matter + 疑问词中的一个特例,这类词的主要区别是：
①疑问词 + ever可引导名词性从句,在主从句中要充当一定的部分.如：
Whoever breaks the rule must be punished.You can choose whatever you like in the shop.
②疑问词 + ever还可引导让步状语从句.如：Whoever breaks the rule,he must be punished,Whatever you do,you must do it well.
③no matter + 疑问词只能引导让步状语从句.如：No matter what you do,you must do it well.No matter who breaks the rule,he must be punished.
