No matter how,however都可以引导让步状语从句,同义,都表示“无论如何”的意思,又都引导让步状语从句,但 有一些区别：
However是比较正式的用语,大都用于书面语,口语中较少使用；
no matter how则比较口语化,它的语势比however重,故常用在强调的场合.
请看下面的例句：
The task must be done,however arduous it may be． 无论多么艰难,这个任务一定要完成.
I”ll take your words,no matter how harsh they may be． 无论语气多么难听,我还是听你的话的.
另外：However有时可表达“然而”、“可是”之意,出现于句中或句尾.例：
They said that it was so；they were mistaken,however． 他们说事情就是如此,可是他们错了.
与之类似区别的词语很多,例如whatever/no matter what、whenever/no matter when、wherever/no matter where、whichever/no matter which、whoever/no matter who.
现将whatever与no matter what的区别如下
no matter what 只能引导状语从句,但whatever既可引导状语从句,还可引导名词从句.
Don”t trust him,no matter what he says.无论他说什么,都别信.
We will be grateful for whatever amount you can afford.你买得起多少,我们都欢迎.
Wherever you go ,whatever you do ,I will be right here waiting for you .无论你走到哪里,无论你做什么,
No matter which dictionary you want to buy,I”ll pay for it.无论你想买哪本词典,我都愿意付款.
