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，只有在狀語從句中，是這樣的。比如說，

No matter what weather it is, we will go to Beijing tomorrow.

=Whatever weather it is, we will go to Beijing tomorrow. 不管天氣如何，我們明天都會去北京。

除此以外，當no matter wh-遇到wh-ever，總是會敗下陣。以下情形，就是只能用wh-ever，不能用no matter wh-

1.主語從句：Whoever comes here will receive a present. 到這的人都能收到一份禮物。

2.賓語從句：He does whatever his mother asks him to do. 媽媽要他做什么，他就做什么。

3.加強語氣，含有“究竟”、“到底”之義：

Whatever do you mean? 你到底是什么意思?

因此，總結起來，只要能用no matter wh-，就一定能用wh-ever，反之卻不成立。
