区别一
no matter what只能放在句首,在句中,只能用whatever,"no matter +疑问词" 或"疑问词+后缀ever" 。
No matter what happened, he would not mind. =Whatever happened, he would not mind.
不管发生什么,他不在意。
区别二
no matter 不能引导主语从句和宾语从句。
(错)Prisoners have to eat no matter what they're given.
(对)Prisoners have to eat whatever they're given.囚犯们只能给什么吃什么。
区别三
what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.
What ever do you mean?= What do you mean on earth?
区别四
whatever 是连接性代词性和形容词,既可以引导让步状语从句,也可以引导名词性从败羡袜中句。同 what一样,whatever 在从句中充当主语、宾语、表语或定语。
如果 whatever引导的察好拍是让步状语从句,可以用no matter取代;如果引导的是名词从句,则不能用 no matter 取代。
区别五
what也可以引导名词性从句意为“the thing which”与“whatever”含义相同.用法完全与whatever相同的词还有whichever,whoever.
