what引导名词性从句
‘what’引导名词性从句的用法
1.当主句含有疑问意思，what在引导名词性从句时也含有疑问含义，它是连接代词，在从句中作主语，宾语，表语或定语
We don’t know what we should do.
我们不知道我们应该做什么。
The problem is what step we should take next.
问题是下面我们应该采取哪个步骤。
2. 当主句不含有疑问意思，what 在引导名词性从句时也不含有疑问含义，它是一个‘特殊关系代词’，表示一个不必要或不可说得十分具体的事，意思为‘the thing which’, 译成‘所。
的东西’。
在这种用法中，what 的含义具有泛指性，即what 的具体含义只表现在what引导的从句中。
We can draw the conclusion from what is said above.
我们可以从上面所说的话中得出结论。
This is what they did.
这就是他们所做的事。
从上述两例中可看出，what具有泛指性，what 什么都可以指，但在句中单从what 本身来考究是看不出来什么意思的，必修到what从句的动词去找。
所‘说’（said）当然是‘话’了，所‘做’的（did）当然是‘事情’了。
