不对1 关系代词在从句中做介词的宾语,介词常提前,但介词提前时,关系代词只用用which whom the school in which he once studied in is very famous
we will go to hear the famous singer about whom we have often talked about2 关系副词 when where why 和介词+which 之间的关系 关系副词 when where why 可以适当用介词+which 来替代.
如 i won't forget the date when(on which) i was born
