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。
