高一英语定语从句教案
一、基本概念
1. 定语从句：
修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。

2. 先行词：
被定语从句修饰的名词
3. 关系词：
引导定语从句的关联词成为关系词有关系代词和关系副词。

关系代词有that, which, who, whom, whose, as；关系副词有where, when, why。

关系词常有3个作用：1）引导定语从句。

2）代替先行词。

3）在定语从句中担当一个成分。

二、关系代词和关系副词的意义及用法
指人：who, that,(指人常用who,不常用that)
主语
指物：which, that
指人：whom, who, that（who常用在在非正式和口语体中）
宾语(关系代词作宾语时常可省略) 关系代词指物：which, that
定语：whose （whose + n.=of which + n. ）
关系词
时间：when
关系副词----状语地点：where = 介词+ which
原因：why
解题技巧：关键看从句缺何种成分
三、例句练习讲解
1.Yesterday I helped an old man ＿lost his way.昨天我帮助了一位迷路的老人。

2.The man ＿you met just now is my friend. 你刚才见到的那个人是我的朋友。

3.This is the pen ＿he bought yesterday. 这是他昨天买的笔。

4.He has a friend ＿father is a doctor. 他有个父亲是医生的朋友。

注意：whose指物时，常用以下结构来代替，例：
门坏了的那间教室很快就会被修好。

The classroom whose door is broken will soon be repaired.
The classroom the door of which is broken will soon be repaired.
你喜欢那本封面是黄色的书吗？
Do you like the book whose cover is yellow?
Do you like the book the cover of which is yellow?
5.I still remember the day ＿I first came to this school.我仍然记得第一次来到这学校
的那一天。

6.Shanghai is the city ＿I was born. 上海市我出生的地方。

7.Please tell me the reason ＿you missed the plane. 请告诉我你错过航班的原因。

注意：关系副词引导的从句可以由“介词+which”引导的从句替换
8.易错题：This is the mountain village (which) I visited last year.
I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词where, when联系在一起而做错题。
