[自主发现2]　

(1)where引导定语从句时，从句的先行词为表示地点的名词，where在从句中作____________状语，相当于“________________”结构。

(2)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]

[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’t believe the reason(that/which) he gave me for his being late.

我不相信他给出的迟到的理由。

Languages Around The WorldPPT，第二部分内容：二、“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]　

Yesterday we visited the West Lake for which Hangzhou is famous.

昨天我们参观了西湖，杭州因其而出名。(be famous for“因……而出名”)

This is the camera with which he often takes photos.

这就是他经常用来拍照的相机。(with the camera“用照相机”)

[自主发现4]　选用介词的依据

(1)根据定语从句中____________的搭配习惯(即固定短语)。

(2)根据____________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。
