关系代词在英语中是很重要的一个代词，可能我们学习的每一个英语的句子里面都有关系代词，只是我们大家都不注意这一点。我们在学习英语的时候，也会有很多的副词，好多人都把这些代词和副词混在一起，不能好的区分开来，这样就导致了学习的失败。下面就是关系代词和副词的区分，我们大家仔细学习一下。

一、 关系代词和关系副词的区别

1、关系代词(that, who, whom, whose, which)所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。

例1. Is he the man who/that wants to see you?(who / that在从句中作主语，指人)

例2. He is the man whom/ that I saw yesterday.(whom / that在从句中作宾语，指人)

例3. They rushed over to help the man whose car had broken down.(whose在句中作定语，指人)

例4. Please pass me the book whose (of which) cover is green.(whose在句中作定语，指物。若指物，它还可以同of which互换)

例5. The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作carry的宾语，指物)

2、关系副词(when, where, why, that)可代替的先行词是时间、地点或理由的名词，在从句中作状语。关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用。

例6. Beijing is the place where (in which) I was born.

例7. Is this the reason why (for which) he refused our offer?

例8. His father died the year (that / when / in which) he was born.

例9. He can’t find the place (that / where / in which) he lived forty years ago.

二、 判断用关系代词和关系副词

方法1： 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。请改错：

1. This is the mountain village where I visited last year.

2. I will never forget the days when I spent in the countryside.

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。句1和句2的where, when都应改为which.。

方法2： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，根据第一点(区别)，也能正确选择出关系代词/关系副词。

例10.This museum is ___ you visited a few days age?

A. where　B. that C. on which D. the one

例11. This is the museum ____ the exhibition was held.

A. where B. that C. on which D. the one (答案：例1 D，例2 A)
