引入：

定语从句在历年高考试题中都有体现，掌握这一语法内容显得尤其重要。

教学目标：

3.情感目标：培养学生竞争意识和自主学习的能力，培养学生学习英语的热情。教学重点：

关系代词与关系副词引导的定语从句。

教学难点：

“介词+关系代词”引导的定语从句。

教学方法：总结归纳法

教学用具：多媒体

教学过程：

（一）定义及相关术语关系代词与关系副词

1.定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。

The man who is shaking hands with my father is a policeman.

2.先行词：被定语从句修饰的词叫先行词。

3.关系词：引导定语从句的词叫关系词。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: when, where, why

关系词通常有下列三个作用：

A.引导定语从句；

B.代替先行词；

C.在定语从句中担当一个成分。

（二）、关系代词that和which在很多情况下可以互换，但下列情况只用that：(通过例句总结归纳得出下列结论)

1.先行词是all,everything,nothing,anything,something,much,little,none 等不定代词，引导定语从句用that .

2.先行词被形容词最高级或序数词修饰时，引导定语从句用that 。

3.先行词被any,some,no,much,few,little,every,all,very,only,last修饰时，引导定语从句用that 。

4.先行词中既有人又有事物时，引导定语从句用that .

（三）不用that，而用which，who，whom的情况

（通过探究得出结论）

1.在非限制性定语从句中，指事物用which，指人用who或whom。

2.在介词后面，指事物用which，指人用whom。

如何判断介词（小组讨论然后总结）

1、看定语从句中动词与介词的搭配

2、看定语从句中形容词与介词的搭配

3、根据先行词判断，所用的介词与先行词搭配

（四）Where 引导的定语从句

先行词是表示地点的名词或含有地点意义的抽象名词，用来引导定语从句。Where 在从句中作状语。

探究：区分where引导的定语从句和状语从句

Where前面有被修饰的地点名词时，是定语从句，否则是状语从句。

若定语从句缺主语或宾语，用which或that引导定语从句。

When 引导的定语从句

先行词是表示时间的名词，用when引导定语从句。在从句作状语。

若定语从句缺主语或宾语，用which或that引导定语从句。

why引导的定语从句

先行词是表示原因的名词，用why引导定语从句。在从句作状语。

This is the reason why ( = for which ) I didn’t come here.

whose 引导的定语从句表示所属关系

as 和 which 的区别

such + 名词 +as +从句

像、、、、、、一样的，像、、、、、、之类

the same +名词+ as +从句

和、、、、、、同类的

which 代替前面的句子，表示“这一点，这件事”

as 代替前面的句子，表示“正如，好像”

（五）限制性定语从句和非限制性定语从句

A.限制性定语从句形式上不用逗号“，”与主句隔开。意义上是先行词不可缺少的定语，如删除，主句则失去意义或意思表达不完整。

The teacher told me that Tom was the only person that I could depend on.

China is a country which has a long history.

B.非限制性定语从句只是对先行词的补充说明，用逗号“，”与主句隔开。如删除，主句仍能表达完整的意思。译法上译成先行词的定语“．．．的” 通常译成主句的并列句。

His mother, who loves him very much, is strict with him.

China, which was founded in 1949, is becoming more and more powerful.
