1、关系代词that ,which ,who 和whom在定语从句作主语,宾语或表语,也就是说,如果在定语从句中,缺少这些成分的话,就用这些词。关系代词whose在定语从句中做定语。关系副词where ,whenh和why在定语从句中充当状语。我们知道,定语从句的结构是(先行词)+关系词+定语从句。关系词的选择主要看定语从句中缺少了什么成分。
2、如:This is the factory ______his father worked ten years ago.在his father worked ten years ago部分,work是一个不及物动词,明显缺少了地点状语,只能用关系副词where。
3、再如:The boy _____ name is Tom didn't come to school yesterday.在_____ name is Tom中,缺少了name的定语,所以用关系代词whose。又如:This is the man ______took my pen yesterday. 在______took my pen yesterday中,明显缺少了主语,所以用who或that。
