英语定语从句关系代词和关系副词的选用    引导定语从句的关系代词和关系副词的选用，比较复杂除了牵涉到所指的先行词是人还是物，所引导的定语从句是限制性的还是非限制性的，以及关系词在从句中充当什么句子成份外，还要根据习惯用法而定。 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. 这是我去年呆过的山村。  I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。    判断改错：    （错） This is the mountain village where I visited last year.    （错） I will never forget the days when I spent in the countryside.    （对） This is the mountain village （which） I visited last year.    （对） 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。  不知不觉背单词 随时随地背单词 新概念英语青少版 例1. Is this museum ___ you visited a few days age?    A. where B. that  C. on which  D. the one  例2. Is this the museum ____ the exhibition was held.    A. where B. that  C. on which  D. the one  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既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。    而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，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做的成分，先行词在从句中做主、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）。  1.
