怎么判断关系副词在定语从句中是作主语、宾语还是状语?最好多举一些例句,

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 together。(when 作地点状语,表示worked 的
地点)
3。That's the reason why he lied to me。(why 作原因状语,表示 he lied to me 的原因)
在定语从句中作主语、宾语的必须是关系代词,而不是关系副词。如：
1。The woman who called me just now is my mother。(who 在从句中作主语,不能省略)
2。The woman (whom) I called just now is my mother。(whom 在从句中作宾语,可以省略)
再问： 那怎么判断关系代词在定语从句中是作主语还是宾语？
再答： 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 woman is 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 called just 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 woman is my mother。 （主句） (whom) I called just 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。
