no matter whatever和however的区别
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" 。
例如：
No matter what happened, he would not mind. =Whatever happened, he would not mind.
不管发生什么，他不在意。
替换：
no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
Whatever + 名词+主谓.这时候的whatever 含有形容词的性质,所以后面才接名词例如：
Whatever dress you are in,you look fantastic.不管你穿什么衣服都很迷人.
2.However + 形容词+ 主谓.这时候的however 含有副词的性质,所以后面才接形容词.（其实,如果是however,那么后面接副词也是可以的）.例如：
However hard I try,I can never win you heart.
另外,whatever 和however,都可以换成 no matter what 以及 no matter how.
whatever是代词，在句子中可以扮演名词能够充当的所有成分,例如主语,宾语等，意思是所...的，认可。
eg1. Whatever he said that day is true.
eg2. He could give up whatever he had to please her.
however是表转折的连词，只能用来连接两个分句。意思是然而
eg. They promised to tell him the address, however, in the end they cheated him again.
