如何判断关系代词与关系副词
方法一：用关系代词还是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,就必须要求用关系代词；而不及物动词则要求用关系副词.例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错：
1．This is the mountain village where I visited last year.
2．I will never forget the days when I spent in the countryside.
[答案]
以上两句都是错误的,应改为：
This is the mountain village(which) I visited last year.
I'll never forget the days(which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词where,when联系在一起.此两题错在关系词的误用上.
方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状）,也能正确选择出关系代词/关系副词.例：
1．Is this museum ________ you visited a few days ago?
A．where B．that
C．on which D．the one
2．Is this the museum ________ the exhibition was held?
A．where B．that
C．on which D．the one
答案：例1 D；例2 A
例1变为肯定句：This museum is ________ you visited a few days ago.
例2变为肯定句：This is the museum _________ the exhibition was held.
在句1中,所缺部分为宾语,而where,that,on which都不能起到宾语的作用,只有the one既作了主句的表语,又可作从句的宾语,可以省略关系代词,所以应选D.
在句2中,主、谓、宾俱全,从句部分缺句子的状语,表地点,既可用副词where,又因in the museum词组可用介词in＋which引导地点状语.而此题中,介词on用的不对,所以选A.
关系词的选择依据在从句中所作的成分,先行词在从句中作主、定、宾语时,选择关系代词（who,whom,that,which,whose）；先行词在从句中做状语时,应选择关系副词（where地点状语,when时间状语,why原因状语）.
