3 .定语从句中关系代词与关系副词的选用
(1)用关系代词还是用关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要用关系代词，而不及物动词则要用关系副词。
This is the village where/in which he was born.
这就是他出生的村庄。
This is the mountain village (which/that) he visited last year.
这就是他去年来过的村庄。
I will never forget the days when/during which I spent thesummer holidays in the countryside.
我将水远不会忘记我在乡下过暑假时的那些日子。
I will never forget the days (which/ that) I spent in the countryside.
我将水远不会忘记我在乡下度过的日子。
(2)看定语从句中缺少什么成分以确定是选用关系代词还是关系副词。如果定语从句中缺少主语、宾语、定语或表语，则这个关系词应是关系代词; 如果定语从句中缺少时间状语、地点状语或原因状语，那么我们应该选用关系副词。
Beijing is the place where(=in which)I was born.
北京是我的出生地。( where在从句中作地点状语)
Hele is the man whom/that I saw yesterday.
他就是我昨天看到的那个人。(whom/that在从句中作宾语)
