Question

定语从句中关系代词或关系副词可以省略吗？

Answer 1

做主语的关系代词在任何情况下都不可以省略
作宾语的关系代词经常被省略，但是若出现“介词+关系代词”时，则关系代词千万不可省略。
例：1.He is a person who I like to talk with.(可填4种）
whom
that
\
2.He is a person with whom I like to talk （这里只能填whom)

Answer 2

首先说关系代词吧：
1.关系代词 that /which/who/whom在句子中作宾语的时候可以省略。
this is the book you (that/which)lent me yesterday.\
this is the person(who/whom) you talked about yesterday.
this is the room (which )they live in.=this is the room where they live.
2.关系副词 that 可以省略
i like the way she speaks.
不知道你是否满意这个答案

关系代词的话，只有当 that在从句作宾语才能省略
关系副词不能省略

Answer 4

关系代词that在从句中充当宾语的时候可以，其他不可以。
关系副词不可以
