what（= the thing that／the things that所的事情）：
what we saw astonished us．等于：
he things that we saw astonished us．
大家所看到的事使大家感到惊讶。
When she sees what you have done she will be furious1．等于：
When she sees the damage that you have done she will be furious．
她如果看到你导致的损毁，她会大发雷霆的。
请务必不要将关系代词what与连接关系词which混淆。记住，which需要用来指前面一个句子中的一个词或一组词。而
what不指前面的任何东西。再者，what常常是动词的宾语，
然而which则常常是动词的主语：
He said he had no money，which was not true．
他说他没钱，这不是实话。
Some of the roads were flooded，which made our journey more difficult．
一些道路被水淹了，这给大家的旅游导致了更多的麻烦。
（参见第82节。）
