关系副词when,where,why 等在定语从句中不能作主语或宾语,只能作状语.如：1.This is the school where we once studied.(where 作地点状语,表示studied 的地点)2.I still clearly remember the time when we worked ...那怎么判断关系代词在定语从句中是作主语还是宾语？1. The woman who called me just now is my mother. 刚才给我打电话的那位妇女是我的母亲。该句子中：The womanis my mother. （主句）who called me just now（定语从句）who 主语called 谓语 me宾语just now状语 2. The woman (whom) I calledjust now is my mother. 刚才我打过电话的那位妇女是我的母亲。 该句子中：The womanis my mother. （主句） (whom) I calledjust now （定语从句）I 主语called谓语whom 宾语just now 状语判断的方法：先找出主句，再看看从句缺的是主语还是宾语。
