Attributive Clauses定语从句是在复合句中起定语作用，修饰名词、代词或整个主句的从句。
被定语从句修饰的词叫先行词。
关系词在定语从句中的作用：①连接主句和定语从句；②指代先行词；③在定语从句中充当一定的成分。
关系代词: who, whom, which, that（主语/宾语）, whose（定语+n）关系副词: when, where, why（状语）一、关系代词在句中作主语。

第五单元语法突破语法知识精讲Grammar定语从句(Ⅱ)一、关系副词引导的定语从句1.when引导定语从句的用法(1)当先行词是表示时间的名词(如time,day,year,month,week等),且关系词在从句中做时间状语时,定语从句用when引导。
(2)when可以换成“介词+which”。
I still remember the time when(=in which) I was in college.我仍然记得我上大学的那段时光。
I have forgotten the exact date when(=on which) this country became independent.我忘记这个国家独立的确切日期了。
特别提醒当先行词是表示时间的名词时,既可以用when引导定语从句,也可以用that或which引导定语从句,关键要看关系词在定语从句中做何种成分。
若关系词在定语从句中充当状语,则用when引导;若关系词在定语从句中充当主语或宾语,则用that或which引导。
Do you remember the days that/which we spent together on the farm?你记得我们一起在农场度过的那些日子吗?(that或which做spent的宾语)Do you remember the days when we chatted with each other all night?你记得我们整夜聊天的那些日子吗?(when在从句中做状语)2.where引导定语从句的用法(1)当先行词是表示地点的名词(如place,room,mountain,airport等),且关系词在从句中做地点状语时,定语从句用where引导。
(2)where可以换成“介词+which”。
This is the hotel where(=in which) they stayed.这就是他们住过的旅馆。
必修一Unit5定语从句复习教学设计
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：
1.知识目标：使学生掌握关系代词与关系副词引导的定语从句，掌握as和which 引导的非限制性定语从句的用法；“介词+关系代词”引导的定语从句；区分限制性定语从句与非限制性定语从句。
2.能力目标：培养学生如何确定关系代词和关系副词的选用以及一些解题技巧。
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.
当堂思维训练：
1. The boy ______ composition won the first prize is the youngest in the group.
A. who
B. whose
C. that
D. which
2. The weather turned out to be very good, ______ was more than we could expect.

D. which
小结：
1、这节课你收获了什么内容？完成了教学目标，掌握了定语从句用法。
2.你学到了什么解题方法？
通过以上学习学生讨论总结解题要领和选择引导词总原则。
解题要领:根据定语从句中所缺成分来确定是用关系代词还是关系副词,决不要因为先行词是时间名词就用when, 是地点名词就用where.
选择引导词的总原则：将先行词放入定语从句中，看其充当的成分，如果充当主、宾、表，用关系代词；如果充当状语，用关系副词。
根据其在从句中的搭配选择相应的介词+which。
课下作业：见课下巩固练习。
板书
定语从句分为限制性定语从句和非限制性定语从句
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。
