关系代词的用法

关系代词
∙1、关系代词用来引导定语从句。

它代表先行词，同时在从句中作一定的句子成分，例如：The girl to whom I spoke is my cousin. 跟我讲话的姑娘是我表妹。

（该句中whom 既代表先行词the girl，又在从句中作介词to的宾语。

）
2、关系代词有主格，宾格和属格之分，并有指人与指物之分。

在限定性定语从句中，that
可指人也可指物，见表：
∙例如：
This is the pencil whose point is broken. 这就是那个折了尖的铅笔。

(whose 指物，在限定性定语从句中作定语)
He came back for the book which he had forgotten. 他回来取他丢下的书。

（which指物，在限定性定语从句中作宾语，可以省略）
