关系副词有哪些？怎么用

关系副词(when、where、why)引导的定语从句,它们后面的句子主干完整，只缺状语，它们都可以等于介词+ which。也就是说关系副词和关系代词可以相互转化，二者的选择主要看该关系词在从句要充当的句法成分。

1、When?

指时间,在定语从句中作时间状语。其先行词是表时间的名词(如:time, day, week, month, etc.)。但并非先行词为"时间名词",就用when引导。当关系词充当定语从句的状语时,用when;当关系词充当主语或者宾语时用which或that?引导。

I still remember the day when my brother joined the army.(作状语，when可以转化为on which)

I still remember the days which/that we spent together. (作spent的宾语)

2、Where?

指地点在定语从句中作地点状语。其先行词是表示地点的名词(如:place, school, room, etc.)。同理，先行词是"地点名词"时,定语从句可用where引导,还可用which/that引导，取决于该引导词在从句中的成分。

This is the factory where he worked last year. (作状语, where可以转化为in which)

This is the park which/that they visited last year. (作visited的宾语)

3、Why?

指原因在定语从句中作原因状语,?先行词通常为reason。同理，先行词为表原因的名词时,还要根据引导词在从句中成分决定用why还是which/that。

The reason why he didn't come to school was that he was ill(作状语).

I don't believe the reason (that/which) he gave me. (作give的宾语)

He asked me the reason that can explain my success. (作explain的主语)

扩展资料

关系副词when,where和why可以用介词+which的形式替换。

1、when=介词+which

I will never forget the day_____ we met for the first time.?

解析：先行词是the day，后面的从句恢复到完整句为：we met for the first time on the day.因此，on the day作状语用关系副词when代替，如果用介词+which，就改成on which。答案为when或on which。

2、where =介词+which

This is the farm______ we worked when we were young.

解析：先行词是the farm，后面的从句恢复到完整句为：we worked on the farm when we were young. 因此，on the farm可以用关系副词where代替，如果用介词，就改成on which。

3、why= for which

I don't know the reason ______he did it.

解析：先行词是the reason，后面的从句恢复到完整句为：he did it for the reason. 因此，for the reason可以用关系副词why代替，如果用介词，就改成for which。
