Section IV Discovering Useful Structures 限制性定语时，从句的先行词为表示地点的名词，where在从句中作地点状语，相当于“介词in /at... + which ” 结构。

⑵关系副词where表示“地点的模糊化”。

当先行词表示某人/物的situation，或
某事发展的stage,或表达某事的某个方面时都可用关系副词where。

常见的先行
词还有point, case position, condition 等。

3.why引导定语从句
［合作探究］
Un successful people can always find reason w hy they' er not doing well.
f Un successful people can always find reas on^or which they' ernot doin
g well.不成功的人总能找到自己表现不好的理由。

［自主发现3］ why引导定语从句时，从句的先行词通常是reason why在从句中作原因状语，相当于“介词for + which ”结构。

［名师提醒］表示时间、地点及原因的名词作先行词时，定语从句可用关系代词引导，也可用关系副词引导。

若先行词在定语从句中作状语时，应用关系副词；若先行词在定语从句中作主语或宾语时，则应用关系代词。

I don' believe the reason(hat/which) he gave me for his being late.
我不相信他给出的迟到的理由。

“介词+关系代词”引导的定语从句
当关系代词在定语从句中作介词的宾语时，我们通常用“介词+关系代词”引导定语从句。

如果指“人”，用“介词+ whom ”；如果指“物”，用“介词+ which” ；关系代词有时也用whose作定语）。

［合作探究］

昨天我们参观了西湖，杭州因其而出名。

（be famous for “因... 而出名”）

（with the camera “用照相机”）

这种无色的、离了它我们就无法生存的气体是氧气。

［自主发现4］选用介词的依据
⑴根据定语从句中谓语动词的搭配习惯（即固定短语）。

（2）根据先行词的搭配习惯（约定俗成，不一定是短语）。

（3）根据句子的意思来选择。
