知识点3：关系副词引导的定语从句

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。
【考查点】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。
如： 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。
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？

知识点4：关系词的选择取决于从句中的谓语动词
1.【考查点】 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。
如： This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.

四、例题精析
【例题1】
【题干】Nearly all the streets are in straight lines, ________ from east to west. Those ________ run from
north to south are called avenues.
A. running; that B. run; who C. running; who D. run; that


【答案】A
【解析】： 主语与run(延伸)是主动关系，所以用现在分词。Those指街道，所以不用who 而用that
来引导定语从句。
