《定语从句教案(10篇)》
定语从句,一个简单句跟在一名词或代词后(先行词)进行修饰限定,就叫做定语从句。的小编精心为您带来了定语从句教案(10篇),希望能够给予您一些参考与帮助。
高中定语从句英语教案 篇1
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:被定语从句修饰的那个名词或代词称为先行词。
3. 关系词:引导定语从句的关联词称为关系词。关系词有关系代词和关系副词。关系代词:who, whom, whose, which, that, as等;关系副词:where, when, why等。关系词常有三个作用:引导定语从句;代替先行词;在定语从句中充当一个成分。
例如:Harry Potter is the most interesting novel that I have read. (that I have read是定语从句;novel是先行词;that 是关系代词,代替先行词novel,在从句中作have read的宾语。)
关系词指代人或物以及在定语从句中充当的成分
关系词指代人或物定语从句中充当的成分
关系
代词that[ ]人或物[ ]主语、宾语、[ ][ ]
表语或状语
which物或主句内容主语、宾语或定语
who人主语或宾语
whom人宾语
whose人或物定语
as人或物或主句内容主语或宾语
关系
副词when时间状语
where地点状语
why原因状语
4. 限制性定语从句和非限制性定语从句
限制性定语从句形式上不用逗号和主句隔开,是先行词不可缺少的部分,去掉它主句意思往往不明确,翻译成先行词的定语,“……的……”。非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,通常翻译成主句的并列句。关系代词that和关系副词why不能引导非限制性定语从句。
His brother who is now a lawyer always encourages him to go to college.
他那个现在是律师的哥哥总是鼓励他上大学。(他还有其他的哥哥)
His brother, who is now a lawyer, always encourages him to go to college.
他的哥哥,现在是律师,总是鼓励他上大学。(他只有一个哥哥)

④当主句的主语是疑问词who或which时,为避免重复要用that。
⑤有两个定语从句时,其中一个关系代词已用which,另一个宜用that。
⑥当先行词在主句中作表语,而关系代词也在从句中作表语时,只用that。
【完成例句】

(19)就像我们指出的那样,这种物质是有毒的。
As was pointed out, this kind of substance is poisonous.
【结论7】关系代词as和which
在非限制性定语从句中,as和which可代替整个主句,相当于and this或and that。二者的区别主要在于:
①as引导的非限制性定语从句既可以在主句前,也可以在主句后,有时还可以在插入句中,常带有“正如……,正像……”的意思。而which引导的非限制性定语从句只能放在主句之后,翻译成“这”。
②as常用于以下固定搭配中:the same+名词+as “和……同样的”,such+名词+as“像……一样的,像……之类的”,…such as…“这样的人 / 物”。(such为代词,作先行词; as在从句中作宾语)
③在以下结构中,一般也用as:
as (it)appears, as (it)seems, as (it)often happens, as (it)was pointed out / said / reported / announced, as (it)was said earlier, as I remember (it), as is well-known, as is known to all, as anybody can see等。
【完成例句】
(20)这就是我一直在找的书。

(23)从1998年到2004年Mike在这所大学学习,在此期间,他学习很努力并当选为学生会主席。
Mike studied at the university from 1998 to 2004, during which time he studied very hard and was made chairman of the Students' Union.
【结论8】“介词+关系代词”引导的定语从句,关系代词指人时用whom,指物时用which。
①某些带有介词的动词短语,介词可以提至关系代词之前,但是在一些固定搭配的短语动词中,由于动词和介词不可以分割,因此不能将介词置于关系代词之前,如take care of, look for, look after, care for等。
②“介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词,有时数词或代词也可以放在“介词+关系代词”之后。
③介词+which / whom+to do结构。这种结构可以改为:介词+which / whom+定语从句。
④在非限制性定语从句中,which可作定语,指先行词(短语或句子)所表示的信息,形成“介词+which +名词”结构,相当于and in / at / during this / that+名词。
二、关系副词的使用
【完成例句】
(24)我仍然记得我们第一次上学的那天。
I still remember the day when / on which we first came to the school.
(25)十年前我住的房子已经被推倒了。
The house where / in which I lived ten years ago has been pulled down.
(26)我不知道他今天看起来不高兴的原因。
I don't know the reason why / for which he looks unhappy today.
【结论1】关系副词的分类和作用
①when指时间,在定语从句中作时间状语;when=表示时间的介词(in / at / on / during…)+which。
②where指地点,在定语从句中作地点状语,where=表示地点的介词(in / at / on / under…)+which。
③why指原因,在定语从句中作原因状语, why=表示原因的介词(for)+which。
【翻译句子】
(27)他回答这个问题的方式是令人惊讶的。
The way in which / that / 不填he answered the question was surprising.
(28) The way which / that he explained to us was quite simple.
【结论2】在以the way为先行词的定语从句中,若the way 在从句中充当状语,则通常由in which或that引导,而且通常可以省略。若the way 在从句中充当宾语,则通常由which或that引导。
【完成例句】
(29)中国是风筝的起源地,并从那里传播到日本、韩国、泰国和印度。
China is the birth place of kites, from where kites spread to Japan, Korea, Thailand and India.
【结论3】有时为了表达更清楚,可以在关系副词where / when前加上介词to, from等。
【疑难】
There is one point that we must insist on.
有一个观点我们必须坚持。(定语从句可还原为:we must insist on the point,所以先行词point在定语从句中作宾语,故用that / which或省略。)
We're just trying to reach a point where both sides will sit down together and talk.
我们正努力做到能让双方坐下来对话。 (定语从句可还原为:at the point both sides will sit down together and talk, 故先行词point在定语从句中作状语,所以关系词用where / at which。)
【疑难剖析】一些特殊的先行词如situation, point, case, activity,scene及period, festival, occasion等要注意具体情况具体分析,作主语、宾语和表语用that / which,作状语用where / when / 介词+which。
三、关系代 / 副词的选择技巧
【完成例句】
(30)我会记住我们一起度过的日子。
I will remember the days that / which / 省略 we spent together.
(根据把定语从句还原成we spent the days together,判断出the days作spent的宾语)
(31) 6月7日是我们开始高考的日子。
June 7 is the day when / on which we begin to take the college entrance examination.
(根据把定语从句还原成we begin to take the college entrance examination on the day,判断出on the day作状语。)
(32 )这是他工作过10年的地方。
This is the place where / in which he worked for ten years.
(根据把定语从句还原成he worked in the place for ten years,判断出in the place作状语。)
【结论】
①用还原法:将先行词放入定语从句中,找到它的原有位置,判断它做什么成分以及判断先行词指人还是指物。
②一般说来,作主语、宾语或表语时,用关系代词;作状语时,用关系副词或介词+which;作定语时,用whose。
四、定语从句和其他句型之间的关系
【例句观察】
He is such a good boy that everyone likes him. (不缺句子成分,that引导结果状语从句)
他是如此好的一位男孩以至于大家都喜欢他。
He is such a good boy as everyone likes. (likes缺宾语,用as充当并引导定语从句)
他是一个大家都喜欢的男孩。
The great white shark is so fierce a fish as eats most of the others. (as充当eats的主语,并引导定语从句)
大白鲨是大多数鱼都吃的一种凶狠的鱼。
【结论】区别such / so…as…引导的定语从句和such / so…that…引导的结果状语从句判断用that还是as, 只要看从句的结构是否完整即可。如果从句缺了主语或宾语就是定语从句;如果从句的结构完整,就是结果状语从句。
【疑难1】区别非限制性定语从句与并列句
— He wrote a lot of novels, none of ______ were popular.
— It's the same with his wife. She wrote some plays, but none of ______ was a success.
A. these; them B. which; which
C. those; which D. which; them
【疑难剖析1】此题应选 D。很容易误选A、B。选对该题的关键是:要注意前面一句的 none of…没有并列连词(说明它才是非限制性定语从句,所以其后填which),而后面一句的none of…前有一并列连词but (说明它与前面一句构成并列句,所以其后填them)。
【疑难2】区别定语从句与名词性从句
①As is known to all, the moon travels around the earth.
②It is known to all that the moon travels around the earth.
③That the moon travels around the earth is known to all.
④What is known to all is that the moon travels around the earth.
【疑难剖析2】
①as引导非限制性定语从句;
②it作形式主语,that引导主语从句;
③that引导主语从句;
④what引导主语从句, that引导表语从句。
【疑难3】区别定语从句与地点状语从句
①When you read the book, you'd better make a mark in the place where you have any questions.
②When you read the book, you'd better make a mark where you have any questions.
③Please put the book in the place where you got it.
④Please put the book where you got it.
【疑难剖析3】①定语从句修饰place; ②地点状语从句;③定语从句修饰place;④地点状语从句。
【疑难4】区别定语从句与强调句、状语从句
①It was this small village (that / which) we got to know each other.
②It was in this small village that we got to know each other.
③It was 1914 when the war broke out.
④It was in 1914 that the war broke out.
⑤It was 1914, when the war broke out.
【疑难剖析4】①定语从句;②强调句;③时间状语从句;④强调句;⑤非限制性定语从句。
【疑难5】定语从句中含有插入语
①He made another wonderful discovery, which I think is of great importance to science.
②The Chinese government has decided to develop the west of China, which, I dare say, will benefit the people there, especially those who are still leading a poor life.
【疑难剖析5】①I think作插入语;②I dare say作插入语。
高中定语从句英语教案 篇2
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.

Being a professional athlete is the only thing that I have ever wanted to do.
I like music that I can sing along with.
I like music that has great lyrics.
I like music that I can dance to.
得出结论1)当先行词是物时
a. 关系代词代替先行词在定语从句中作主语时,用which/that引导,且不能省略。b. 关系代词代替先行词在定语从句中作宾语时,用which/that引导,且可以省略。
2)当先行词是人时
a. 关系代词代替先行词在定语从句中作主语时,用who/that引导,且不能省略。b. 关系代词代替先行词在定语从句中作主语时,用who/that/whom引导,且可以省略。
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 called Qinghuaci.
Who I like best.
It’s an animal that/which is very strong.
It’s an animal that/which has long nose and big ears.
It’s an animal that/which I like very much.
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 prefer shoes that are cool.
2) I like a pizza that is really delicious.
3) I love singers who are beautiful.
4) I have a friend who plays sports.
学生观察后得出的结论为:
who/that在定语从句中做主语时,谓语动词的单复数应与先行词保持一致。
第四环节:小节本堂课的内容
什么是定语 ?
什么是定语从句?
定语从句的结构是什么?
关系词有几重作用?
此环节让学生对所学的知识加以升华,并在大脑里形成知识框架,把知识系统化。
第五五环节:巩固练习---以检查学生是否真正掌握本堂课的知识,实践证明,学生掌握得很好。
第六环节:合作探究
留给学生的问题
1.如果先行词既有人又有物,用什么关系词?
2.如果先行词是时间,用什么关系词?
3.如果先行词是地点,用什么关系词?
4.关系词whose怎么用?
通过此环节给学生留下思维拓展的空间,也为以后的学习做好铺垫,体现学习的延续性。
课堂小结:通过例子让学生总结定语从句的规律和特点,同时总结不同关系词的用法。在这节课中,学生对定语从句这一语法项目有了不同程度的巩固和深化。
六、课后反思:
优点:本节课教学目标明确,条理清楚,板书设计合理,教学内容紧扣学生生活实际,学生在教师的引导下自主学习、合作学习,较好地归纳了定语从句的特殊用法,并能用定语从句写文章,完成了学习任务。
不足:
1、在引入部分没有充分引导学生把他们描述图片的简单句用关系词合并为定语从句。
2、最后一个环节用定语从句翻译文章时间安排不足,应多用二至三分钟的时间对学生的翻译进行进一步分析总结,让学生提出更多的修改意见。教学机智:本节课学生在归纳特殊用法时,提出了设计内容之外的规律,教师能给予肯定,并提出在下一教学环节进一步讨论。能够放手让学生发表不同的意见,并适时进行点播。
再教设计:第一环节讨论图片,把学生说出的简单句写在黑板上让学生改为复合句,使引入部分目标更明确。最后翻译文章留出十分钟时间让更多学生展示范文,师生共同提出修改意见。

《电话号码》教案 篇4
活动设计背景
现在手机的普及,幼儿很少接触到座机的使用,通过有用的电话号码让小朋友了解座机的号码与手机号码的不同之处及所包含的意义。
活动目标
1.复习9以内的数字并数数。
2.尝试编电话号码,感知号码的多变性,初步了解特殊号码。
教学重难点
重点:了解座机电话号码的构成。
难点:尝试编电话号码,感知号码的多变性。
活动准备
1.教具准备:小羊小兔图片、通讯录、号码条、电话机、特殊号码条、神秘袋。
2.学具准备:人手一份数字0—9贴纸,白纸每人一张。
活动过程
一、开始(导入)部分
1.出示电话机
师:这是什么?(电话机),那电话又什么作用呢?(聊天,问好等)
师:是啊,电话的作用可大了,有急事找别人,只要打电话就可以告诉他们了。要是想念亲人,想念你的朋友,一拨电话,“嘟”就可以了。不管路有多远,也可以听到他们的声音,和他们聊聊天,电话确实给我们带来了许多方便呀!
师:这不,明天我们要举行运动会了,要邀请一下小兔和小羊,(拿出小兔,小羊)我们赶紧给他们打电话吧!(拿电话)
基本部分
出示电话本
师:打电话之前我们要做什么呢?(拨电话号码)
师:让我们一起来查查小兔的电话号码是多少呢?(翻开电话本),大家一起来念一念。
师:(师拨打小兔电话号码)小兔,明天我们要举行运动会,希望你能参加,太好了你能来,再见。
师:咦!还有谁没有邀请呢?(小羊)让我们用同样的方法来找一找小羊的电话号码吧!
师:(邀请小朋友,请一位小朋友来查查小羊的电话号码)告诉小朋友,你找到小羊的电话号码是多少呢?(幼念号码师拨电话)。
师:喂,小羊,明天我们要举行运动会,希望你能来参加。太好了,你能来。
师:哎呀!这电话号码也很神奇,只要一拨这些数字,就能找到小兔他们了,这电话号码是由什么组成的?(数字)这些号码是由不同的数字组成,电话号码不止这两个,还多着呢!你瞧!(出示电话号码)让我们一起念一念。
二、感知数字的丰富变化
1.观察比较两三组电话号码
师:这些号码都是由几位数字组成的?(8位)
师:对了,我们路桥的家庭号码是由8位数字组成的。
师:我们来看看这两组电话号码哪两个数字是一样的呢?
师:你们的眼睛真亮,能够找出8和2这两个数字一样,为什么这两个数字一样呢?(幼儿自由猜测)
师:唉呀!其实我告诉你这里藏着一个大秘密,第一个数字8代表的是台州地区,第二个数字2代表的是路桥地区,小朋友可要记住了,我们台州地区第一个数字都是8带头,紧接着是路桥数字2,后面的数字是不同的,可以任意选择0—9的数字排列,电话号码的数字排列不同,就能编出许多不同的电话号码。
三、幼儿操作,设计号码
1.讲解要求
师:现在我们来设计一下新的电话号码,黄金海岸造了很多的房子,安装了新的电话,我们现在就帮电信局里的叔叔阿姨设计新的家庭嗲话号码吧!一定要记住是8开头紧接着是2,后面的数字随意排练,但是一定要8位数字的电话号码,小朋友们记住了吗?
2.师提示贴数字的方法,想想小动物家庭号码需要几位数字,第一个是8,第二个数字一定是2。
3.欣赏幼儿编的号码
师:我们请几位小朋友来说说他编的电话号码吧!
师结:小朋友们真棒!编出了那么多不同的电话号码。
结束部分
师:小朋友今天棒极了,学习了有关电话的很多本领,还自己设计了电话号码,实际上还有一种电话号码是11位数的,就是手机号码,这个号码我们下次再认识吧。
活动延伸

师:你们看!(出示神秘袋)老师这里有个神秘袋里面藏着特殊的电话号码,你们想知道这些号码是什么吗?
请几位小朋友上来摸号码。
师:老师告诉小朋友这也是电话号码,你们说说这是几位数的电话号码(3)。
师:诶!我们刚才说的电话号码都是8位数的,怎么会有3位数的电话号码呢?老师告诉小朋友8位数的电话号码是我们平时能拨的电话号码,这个不是普通的号码而是特殊的号码,今天我们就来认识几个特殊的号码,谁知道110是什么时候拨打的(抓小偷)谁还知道哪些3位数的特殊号码。
师结:正因为号码实在太多了,所以人们想出既方便我们记住又方便我们拨打的特殊号码。
师:现在我们玩个小游戏,如:我发现一座房子着火了,你们马上说拨119……
教学活动反思
中班的幼儿对数字非常感兴趣,对周围有数字的事物充满了好奇,再加上现在每个孩子家里都有电话,当电话铃声响起时,孩子们往往会抢着接电话。因此,我选上中班数学活动:有用的电话号码,以孩子生活中随处可见的数字为载体,通过综合化的形式,情景化的过程,生活化的内容,经验化的讲述让幼儿发现、了解电话号码的作用,体验有了电话号码给我们生活带来的方便。让幼儿在玩中学,促进幼儿数概念的形成与发展。
这节课也有不足之处:如在查询小动物的电话号码,电话本让全班的幼儿看到满足他们的好奇心是不是更加好呢。介绍“8”和“2”的时候,我在设计课题之前,应该把这两个数字的颜色和其他数字区分开来,我相信幼儿会更加的好奇这两个数字的特别之处并掌握他们代表的意义。在设计号码这个环节中,我向幼儿讲述的不清楚,导致有部分幼儿设计的家庭电话号码有11位数,最后通过欣赏幼儿设计的电话号码,把这个错误纠正了过来。
Ⅳ. 关系代词that & which的区别: 篇5
⒈ 只用that的情况
① 先行词为all, everything, anything, nothing, little, much等不定代词时。
eg. There is nothing ( ) can prevent him from doing it.
② 先行词被any, only, few, no, very, little 等修饰时。
eg. This is the very book ( ) I’m looking for.
③ 先行词被形容词最高级或序数词修饰时。
eg. The first place ( ) they visited in Guilin was Elephant Trunk Hill.
This is the best film ( ) I have ever seen.
④ 先行词既有人又有物时。
eg. He talked about things and persons ( ) they remembered in the school.
⑤ 先行词被the only, the very修饰时。
eg. Mr. Smith is the only foreigner ( ) he knows.
⑥ 句中已有who或which,为了避免重复时。
eg. Who is the man ( ) is standing beside Tom?
⒉ 不能用 that的情况:
① 引导非限制性定语从句;
eg. He had failed in the maths exam , ( ) made his father very angry.
② 介词 + 关系代词。
eg. This is the room in( ) my father lived last year.

设计意图:
随着社会生活现代化进程的加快,现代生活给幼儿带来的潜在危险日益突出,像火灾、溺水、拐骗、突发事件等一系列危险时刻威胁着年幼的儿童,而中班幼儿还处在未成年期,缺乏生活经验和自我保护能力,在日常生活中很容易发生意外伤害。为了让幼儿适应社会,学会更好地保护自己,知道一些急用的电话号码,在自己遇到紧急问题时会正确使用这些电话号码。特设计些活动。
活动目标:
1、引导幼儿学会处理一些突发事件,知道几个常用的报急电话,并学会拨打报急电话。

活动过程:
一、让幼儿观看第一张幻灯,引起幼儿的兴趣。

教师提问:“这个时候,小明该怎么办呢?”
2、幼儿讨论后请个别幼儿回答。

bsp; 二、教幼儿学习打“110”
1、出示电话机,请个别幼儿上来拨打。
2、教师示范讲解拨打报警电话:先拿起听筒,拨号码110,听到嘟嘟的几声长音,表示电话通了,对方接了电话以后,向对方讲清什么地方发生了什么事情。警察叔叔接到电话后就会马上赶来把坏人抓住。 三、幼儿观看第二张幻灯,引导幼儿学习拨打急救电话。
1、小玲和奶奶在家正看着电视,奶奶突然昏倒在地上,小玲急得哭了起来。
教师提问:“这个时候,小玲该怎么办?”(请小朋友动脑筋帮小玲想办法。)
2、幼儿讨论后请个别幼儿回答。
3、教师说:“我们来看小玲是怎么做的。”(打电话给爸爸)
