no meter howno meter what用法和whatever,however的区别,
no matter what 只能引导让步状语从句不可以引导名词性从句.如：No matter when I'm unhappy,it is my friend who cheers me up .不管什么时候我不开心了,总是我的朋友使我振奋起来.
whatever既可以引导让步状语从句,也可以引导名词性从句.如如：Whatever was said here must be kept secret.我们在这儿说的无论什么都必须保密.（名词性从句 ）如：The lawyer seldom wears anything other than a suit ,whatever the season is.无论什么季节,这位律师除了一套西装以外很少穿其他衣服.（让步状语从句）
whatever在句子中做宾语,如whatever you want,无论你想要什么 .
however在句子中做状语,如 however you want it,无论如何你想要它.
前者的句子必缺少成分,you want句子不完整,缺宾语.
而后者用的句子是完整的,you want it,这句话是完整的.
所以,判断是whatever还是however,只要判断句子完整与否就好了.
他们都可以用来引导让步状语从句，但whatever，however还可以引导主语从句，而no meter howno meter what只能用于让步状语从句，
