no matter what 和whatever 有什么区别

　　no matter what 和whatever 的区别如下：

　　一、 引导名词性从句时，只能用whatever。例如：

1. 无论他做什么都是对的。

   正：Whatever he did was right. （引导主语从句）

   误：No matter what he did was right.

2. 无论他说什么似乎都有道理。

   正：Whatever he says sounds reasonable. （引导主语从句）

   误：No matter what he says sounds reasonable.

3. 山羊找到什么就吃什么。

   正：Goats eat whatever they find. （引导宾语从句）

   误：Goats eat no matter what they find.

　　二、 引导状语从句时，两者可换用。例如：

1. 无论你说什么，我都不会相信你。

   正：Whatever you say, I won't believe you.

   正：No matter what you say, I won't believe you.

2. 无论发生什么，都要保持镇定。

   正：Keep calm, whatever happens.

   正：Keep calm, no matter what happens.
