关系副词引导的定语从句语法讲解

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。

1. 关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which" 结构交替使用，例如：

There are occasions when (on which) one must yield.

Beijing is the place where (in which) I was born.

Is this the reason why (for which) he refused our offer?

关系代词在定语从句中作宾语时，可以省略。

(1) Behind one door was a hungry tiger (that/which) the guards had put there.

(2) The tiger would immediately jump upon the poor man (whom/who) the guards had brought to the arena.

whose只用作定语,可以用来指人或物; 若指物，它还可以同of which互换, 例如：

(1) They rushed over to help the man whose car had broken down.

(2) Please pass me the book whose (of which) cover is green.
