1、可引导的句子不同
no matter what只能引导让步状语从句。
例句:No matter what you say,I won't believe you.
无论你说什么我也不会相信的。
在引导名词性从句(如主语从句、宾语从句、表语从句),则只用whatever。
例句:Whatever he did was right.
无论他做什么都是对的。
2、语气程度不同
whatever还可用于加强语气,相当于what ever, what on earth等。no matter没有这种用法。
如: Whatever is the matter?
这是怎么回事?
3、从句动词不同
有时no matter what引导的从句中,动词可以省略。
例句:In our company, every body is well taken care of, no matterwhat his position (is).
在我们公司,每个人都得到很好的照顾,不管他地位如何。
Ⅰ.no matter what“不管什么,无论什么”用来引导让步状语从句。类似的词组还有:no matter where “不论哪里”, no matter which “不论哪一个”,no matter how“不论怎样”如:
① They are going to win the football match, no matter how bad the weather is. 不管天气多么糟糕,他们会赢得这场足球比赛。
② No matter who knocks, don’t open the door. 不管谁敲门,都不要开门。
③ Give me a call first no matter when you come. 不管什么时候来,都请你先给我打个电话。
Ⅱ.whatever 是连接代词,可以作“无论什么”解,引导让步状语从句,可以这样用的连接代词或连接副词有whoever, whichever, whenever, wherever, however等。如:
① Whatever you do, do your best. =No matter what you do, do your best. 无论你干什么,都要尽最大努力去干。
② Whoever telephones, tell him I am out. = No matter who telephones, tell him I am out. 无论谁给我打电话,就说我出去了。
③ Wherever he may be, he will be happy. = No matter where he may be, he will be happy. 无论在什么地方,他都是乐呵呵的。
Ⅲ.whatever 还可以解作 “凡是……的;所……的东西”(anything that),用来引导一个名词性从句,这时不能用no matter what 替换。如:
① Take whatever you want. 你要什么就拿什么吧。
② Whatever I have is yours. 我所有的东西全都是你的。
