一、教材分析
本节课的学习任务就是能初步掌握及运用定语从句，让学生用定语从句来完成对喜欢的人物进行描述，如I like music that I can dance to. I prefer movies that can cheer me up.等。为了使学生顺利地完成教学任务，教师以学生为主体，为学生设计了几个以他们的认知水平出发的符合生活实际的他们感兴趣的一环扣一环的子任务，每个子任务紧紧围绕总任务展开，再深入，在一个一个完成任务的活动中培养学生的能力。
二、学情分析
语法学习一直是学生学习的重点及难点，而定语从句在历来的中考试题中都有所体现，因此，掌握这一内容显得尤其重要。我所教的班级学生英语基础比较差，再加上传统的语法教学基本以呈现理论为主再辅以练习，相对枯燥，学生兴趣不够，容易分散注意力，所以应溶入一些新的教学元素，借用大家感兴趣的话题促进学生的热情，增强学习的效果。
三、教学目标
2、掌握关系代词that, which, who, whose关系副词when, where, why的基本用法。
能力目标：能够在真实的交际环境中正确应用关系代词that, which, who, whose关系副词when, where, why引导的定语从句。
情感目标：1、通过学习调动学习积极性，使学生体会到英语的趣味性和实用性。同时促进同学间积极合作交流，发展同学间的友谊 。
初中英语教学设计2、通过游戏，学会合作，建立自信心和集体荣誉感以及综合运用所学知识解决实际问题的能力
四、教学重难点
1、了解定语从句的句法作用和结构，特别是关系词的正确使用；
2、学会分析句子成分。
五、教学方法
以学生为主体，用多媒体辅助教学，联系生活采用讨论、协作、探究的小组活动和语法规则自主归纳演绎的教学模式，引导学生灵活运用所学语法知识。
六、课前准备
1、学生出所学课文中出现的定语从句。
2、学生课前预习定语从句的讲解并试做习题。
3、教师准备相关多媒体课件。
七、教学过程
Step 1 Leading-in
T：Which apple do you prefer?
A：I prefer the red apple.
B: I prefer the green one.
通过导入引出定语的定义：
定语是用来修饰、限定、说明名词或代词的品质与特征的。
修饰名词或代词的词、短语或从句称为定语。
his desk （物主代词） Tom’s father（名词所有格）
a beautiful city（形容词） three teachers（数词）
women teachers （名词） in the room above（副词）
a developing country （现在分词）
a developed country（过去分词）
There is nothing to do today. （不定式）
an article about how to learn English（介词短语）
a city which is beautiful（从句）
Step 2 Presentation 1
T: Robot? Which robot do you prefer?
SA:I prefer the robot which can play the guitar.
SB:I prefer the robot which can clean the house.
SC:I prefer the robot which can sing.
通过例句引出定语从句
定语从句：1、含义：修饰名词或代词的句子叫定语从句。
2、定语从句位置：一般紧跟在所修饰的名词或代词之后。
3、结构： 先行词 + 关系词 + 句子
关系词：关系代词: that, which, who, whom, whose
关系副词: when, where, why
例句分析：
I like to have friends who/that are different from me.
I like musicians who/that play different kinds of music.
The teacher that/who/whom I like best often encourages me to fight for my dream.
My friends and I talked about the rules that/which we have in school.
Being a professional athlete is the only thing that I have ever wanted to do.
I like music that/which I can sing along with.
I like music that/which I can dance to.
得出结论：先行词人 (n.) + who /that/whom+ 从句
先行词物 (n.) + that / which+ 从句
小结：1、that－ 既可指人，也可指物，作主语，不能省略；作宾语，可以省略。
2、which－指物，作主语，不能省略；作宾语，可以省略.
3、who－ 指人，作主语，不能省略；作宾语，可以省略,（常用whom）
4、Who/that 在定语从句中作主语时，谓语动词的单复数应与先行词保持一致。
5、关系代词who / that的作用：
a. 做代词，代替先行词
b. 在从句中担任句子成分：主语或宾语
c. 做连词，把主句和从句连接起来
跟踪练习
1、判断Who/that 在从句中担任主语还是宾语。
1）I love singers who write their own songs
2）He is the man who I met yesterday.
3) I like music that I can dance to.
4) I prefer a sandwich that is really delicious.
2、改写成定语从句：①出两个简单句的共有成分；
②将从句中的共有成分去掉；
③用关系词引导剩下的从句，并紧接在被修饰词之后．
1) I like music. The music is loud and exciting.
2) She loves movies. The movies are romantic.
3) Tony likes music. He can dance to the music.
4) I love the girl. The girl has long hair.
Step 3 Presentation 2
例句分析：
I like the teacher whose classes are very interesting and creative.
She is the girl whose invention got the first prize in the school competition.
得出结论：先行词（人、物）+ whose+ 从句
Step 4 Presentation 3
例句分析：
Do you remember the days that we spent together?
I won’t forget the days when/during which you are away.（when：指时间，作状语）
I visited the factory that/which you told me yesterday.
This is the factory where/in which my father works? （where：指地点，作状语）
The reason (that/which) he gave for being late was that his alarm didn’t go off.
Do you know the reason why he was late for school? （why：指原因，作状语）
得出结论：先行词在从句中做状语用关系副词when, where, why
