牛津实用英语语法 83 what（关系代词）和which（连接关系词）

　　what(= the thing that/the things that所的事情)：

　　what we saw astonished us.相当于：

　　he things that we saw astonished us.

　　我们所看到的事使我们感到惊讶。

　　When she sees what you have done she will be furious.相当于：

　　When she sees the damage that you have done she will be furious.

　　她要是看到你造成的损坏，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必须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.

　　他说他没有钱，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，这给我们的旅行造成了更多的麻烦。
