wh-ever 和 no matter wh-的比较
很多小伙伴都知道：
no matter what=whatever
no matter who=whoever
no matter which=whichever
no matter whom=whomever
no matter where=wherever
no matter when=whenever
no matter how=however
BUT，只有在状语从句中，是这样的。比如说，
No matter what weather it is, we will go to Beijing tomorrow.
=Whatever weather it is, we will go to Beijing tomorrow. 不管天气如何，我们明天都会去北京。
除此以外，当no matter wh-遇到wh-ever，总是会败下阵。以下情形，就是只能用wh-ever，不能用no matter wh-
1.主语从句：Whoever comes here will receive a present. 到这的人都能收到一份礼物。
2.宾语从句：He does whatever his mother asks him to do. 妈妈要他做什么，他就做什么。
3.加强语气，含有“究竟”、“到底”之义：
Whatever do you mean? 你到底是什么意思?
因此，总结起来，只要能用no matter wh-，就一定能用wh-ever，反之却不成立。
