定语从句讲解篇1:定语从句最新课件定语从句课件篇一
一、设计背景
1．初步掌握及运用定语从句，如让学生用定语从句来完成对人物喜欢的人物进行描述，如I like music that I can dance to. She is the only one who’s studying French.等。
2．本课的学习任务就是能初步掌握及运用定语从句，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．教学目标
（1）语言目标：能用定语从句较自如地描述及谈论人和物。在活动中训练学生的听力，口头表达能力，培养学生的观察，想象和创造力。
（2）情感目标：促进同学间积极合作交流，发展同学间的友谊。
2．教学方法：多媒体的运用能创设真实的语言情景，学生也很感兴趣，极大地鼓动了学生学习英语的积极性，而且呈现在课堂上能使教学更生活化，也更直观和具体。
三、教学方法
以学生为主体，用多媒体辅助教学，通过帮助学生理解、归纳、总结、讨论等方式学习定语从句，由于本节课是学生第一次系统学习定语从句，要达到让学生初步掌握定语从句这一目的。
四、学法指导、自主学习、合作学习
五、教学过程
第一环节：观察以下例句：
1.The red pen is broken.
2.The pen on the desk is broken.
3.The pen that I bought yesterday is broken.
导入：通过对定语的理解，导入定语、定语从句的概念，定语：用来修饰名词或代词的词、短语或句子，当修饰词是一个句子时被称为定语从句。通常置于它所修饰的词之后，这种被修饰的词叫做先行词，引导定语从句的关联词为关系代词和关系副词，关系代词在定语从句中可用作主语、宾语、定语等，关系副词在定语从句中只用作状语。
例句分析：
I like to have friends who are like me.
I like to have friends who are different from me.
He is the only one who is studying French.
Be careful of the person who doesn’t speak and the dog that doesn’t bark.

第二环节：在学生对定语从句有了初步的了解后，创设情境，学以致用，让学生分组活动，根据多媒体呈现的情境，有创造性地造句：
This is a singer who/that …
who is a boy.
who is very shy.
who writes his own songs.
who has a song calledQinghuaci.
Who I like best.
It’s an animal that/which is very strong.

第三环节：在学生对一般的规律都把握好以后，把学生的易错点和定语从句的考点呈现在屏幕上，让学生仔细观察并作出总结，该环节设计得很好，很好地训练了学生的观察能力和主动探究的能力，效果较好。
仔细观察：你会发现什么？
1) I prefershoesthat are cool.
2) I likea pizzathat is really delicious.

学生观察后得出的结论为：
