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 with you together.
to + whom for +which
in + which in + which
There are occasions when (=on which) one must yield. 任何人都有不得不屈服的时候。
Beijing is the place where (=in which) I was born. 北京是我的出生地。
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。 1. Is this museum ___ D you visited a few days age? A. where B. that C. on which D. the one 2. Is this the museum ____ A the exhibition was held? A. where B. that C. on which D. the one
Is this the reason why (=for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？

关系副词when, where, why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。
