C 介词的宾语

介词位于 which 之前或者位于从句之后，但不那么正式：

D 与短语动词连用的 which

像下面的短语动词 look after，look forward to，put up with（参见第三十八章）都应被看做一个整体，即介词/副词不应与动词分开：

This machine，which I have looked after for twenty years，is still working perfectly．

这台机器我已经照管了20年，现在仍然没一点儿毛病。

Your inefficiency，which we have put up with far too long，is beginning to annoy our customers．

我们对你的不称职容忍得太久，而顾客也开始对此感到不满意了。

whose 一般用来指动物和事物，of which 可以用来指物，但是

除在很正式的英语中之外，比较罕见。
