1、一、“介詞+關系代詞”引導的定語從句基本構成 1.“介詞+關系代詞”結構引導的定語從句中，關系代詞只能用which（指物）或whom(指人) ，即：介詞+which/whom。 （1）The man to whom you spoke is a teacher. （2）The city in which she lives is far away. （3）The little girl is reading a book,in which there are many cartoons.注意：當介詞放在關系代詞的前面時，用在介詞后的關系代詞不能省略。 2.關系副詞when，where，why可

2、用“介詞which”來代替。關系副詞實際上是介詞先行詞。其中when=表時間的介詞（如：in，at,on,during等）+which；Where=表地點的介詞（如：in，at,on,under等）+which；Why=表原因的介詞（如：for）+which (1)當先行詞表示時間，定語從句中缺少時間狀語時，通常用關系副詞when引導，此時也可選用表示時間的介詞which來代替關系副詞when。 I still remember the day when I came here. ( on the day =when) (2)當先行詞表示地點，定語從句中缺少地點狀語時，通常用關系副詞where

3、引導，此時也可選用表示地點的介詞which來代替關系副詞where。 This is the house where I lived last year. ( in the house= where) (3)當先行詞為reason，定語從句中缺少表示原因狀語時，通常用關系副詞why引導，此時也可以用for which來代替關系副詞why。There are many reasons why people like traveling. (for the reasons =why)3、whose可轉換為“ of +關系代詞”型。They live in a house, whose door o
