1.when引导定语从句

[合作探究]

→I will never forget the day on which I first saw you.

我永远不会忘记第一次见到你的日子。

[自主发现1]　when引导定语从句时，从句的先行词为表示____________的名词，when在从句中作时间状语，相当于“介词in/at/on/during...＋which”结构。

2.where引导定语从句

[合作探究]　

After living in Paris for fifty years he returned to the small town where he grew up as a child.

→After living in Paris for fifty years he returned to the small town in which he grew up as a child.在巴黎生活了50年后，他回到了儿时成长的那个小镇。

The accident has reached to the point where both their parents are to be called in.

事情发展到如此地步，不得不请双方家长来一趟了。

[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]

Unsuccessful people can always find reasons why they’re not doing well.

→Unsuccessful people can always find reasons for which they’re not doing 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____________状语，相当于“________________”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’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”)

The boss in whose company Mr King worked heard about the accident.

金先生所工作的公司的老板听到了这起事故。(in the boss’ company “在老板的公司”)

The colorless gas without which we cannot live is called oxygen.(without the colorless gas “没有这种无色气体”)

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

(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。

[巩固内化2]

用“介词＋关系代词”填空

①This is the man ________________ I just shook hands.

②None of us know the reason ________________ Tom was absent.

③Do you remember the day ________________ you joined our club?

④There is a big window ________________ I can see the railway station.
