定语从句教案 篇一

一 什么是定语从句

阅读下列句子,找出哪一句是定语从句

1。 My doctor told me to live where the air is fresh 。

2。 Tom was sleeping when the door bell rang 。

3。 Do you remember the teacher who taught us English at middle school ?

4。 Can you tell me when the Flight 5571 will depart ?

在复合句中充当定语的从句叫定语从句。定语从句的作用相当于形容词,用来修饰主句中的某一个名词或代词或整个句子。被定语从句修饰的词叫先行词,定语从句一般紧跟在它所修饰的先行词之后。因此,通常定语从句被视为一个句子与一个名词的关系。在先行词和定语从句之间起连接作用的叫关系词。关系词有关系代词和关系副词两种。

例如:

He is the boy who often goes to school late。

注意

关系词在定语从句中的三大作用:

1。 连接作用---连接先行词和定语从句。例如:

I gave her all the money that I had 。我把我所有的钱都给了他。(that 连接先行词money 和定语从句I had )。

2。 替代作用---在定语从句中替代从句所修饰的先行词。例如:

The man who lives next door is a famous teacher。

2。 成分作用---在定语从句中作主语、宾语、定语或状语。 例如:

I like pictures which are painted in the traditional Chinese style。 我喜欢传统的中国画(which 在定语从句中作 主语)。

二 关系代词和关系副词的用法

阅读下方的句子,根据从句的语法特点将其归类,幷把句子序号表格填入空缺处。

1。 She is the old woman that witnessed the accident this morning 。

2。 Mary is the girl who works in Japan 。

3。 Is this the key which you are looking for。?

4。 October 1,1949 is the day when New China was founded。

5。 The house which stands on the top of the hill was built last month 。

6。 The student whom the teachers are talking about has won the first prize in the English contest。

7。 He lied to the police officer, which made things even worse。

8。 This magazine belongs to the teacher who teaches us history。

9。 Tom is reading in the room where the others are watching TV 。

10。 He failed in the exam ,which surprised us all。

11。 I don’t know the reason why she looks unhappy today。

12。 I’ll never forget the day when I joined the League 。

13。 He’s got himself into a dangerous situation where he is likely to lose control over the plane 。

关系代词和关系副词的用法

定语从句类型 特点 句子序号

由关系代词which that whowhom 引导 关系代词在从句中作主语

关系代词在从句中作宾语

关系代词which 指代前句所属之事

由关系副词when wherewhy 引导 定语从句中不缺主语或宾语;when where why 充当从句的时光、地点、原因状语。

Where 所指代的是一个抽象的地点,例如某一种状况、某一个领域。

巩固练习

完成句子

1。 Alexander Bell was the man _______________________(发明电话的人)。

2。 The present ____________________________________(她生日那天我送她的) is still unopened。

3。 Carol said the work would be done by October。__________________________,(我对此十分怀疑)。

4。 The film brought the hours to me __________________________________(当时我得到很好的照顾) in the faraway village 。

4。 If a shop has chairs _______women can park their men ,women will spend more time in shop 。

A that B which C when D where

5 I work in a business _________almost everyone is waiting for a great chance 。

A how B which C where D that

三 关系词使用的注意事项

引导定语从句的关系词的选用比较复杂。除了牵涉到所指的先行词是人还是物,所引导的定语从句是限制性的还是非限制性的,以及关系词在从句中充当什么句子成分外,还要根据习惯用法而定。

(一) 只能使用that ,who , whose 的定语从句。

请阅读以下句子,根据用法分类,将句子序号填入表格中适当的位置。

1、Here is the boy who wants to see you 。

2、All that glitters is not gold 。

3、Who is the man that came this morning 。

4、Which is the bag that you lost 。?

5、He talked about the teachers and schools that he had visited 。

6、Anyone who breaks the law shall be punished。

7、His mother ,who loves him very much ,is strict with him。

8、Is there anything that you don’t understand ?

9、Mary is the girl whose parents work in Japan 。

10、He is the very person that the police are looking for。

11、Those who are against the plan put up your hands please。

12、This is the longest bridge that I have ever seen 。

定语从句教案 篇二

Ⅰ。 定义

定语从句,起形容词的作用,在句中常用来修饰名词或代词。被修饰的词称为先行词,引导定语从句的词称为关系词, 关系词的作用一是放在先行词与定语从句中间起引导作用;二是在好处上代替先行词,并在从句中充当一个成分。其中关系代词:who, whom, whose, which, that, as;关系副词:when, where, why。

eg。 She is the girl who sings best of all。

The pen which my uncle gave me is missing。

He lives in a house whose windows face south。

The factory where my father works is in the east of the city。

Perhaps the day will e when people will be able to breathe clean air in cities。

Ⅱ。 关系代词

1。 先行词是人,作主语,关系代词用who, that

eg。 He is a mannever leaves today’s work till tomorrow。

The boy is standing there is my cousin。

2。 先行词是人,作宾语,关系代词用 whom, who, that,

eg。 Here is the man you’ve been expecting to meet。

The man you met yesterday is Mr。 Smith。

3。 先行词是物,作主语,关系代词用which, that

eg 。 The train has just left is for Guangzhou。

Children like to read books have wonderful pictures。

4。 先行词是物,作宾语,关系代词用which, that,或省略

eg。 The book you borrowed yesterday is really interesting。

The pen my uncle gave me is missing。

5。 先行词是人、物,作定语,关系代词用whose

eg。 He is the professor name was Jackson。

China, population is the largest in the world, is developing very fast。

Ⅲ。 关系副词

1。 先行词是表示时光的名词,在定从中作时光状语,关系代词用when

eg。 I can’t remember the date he went abroad。

I’ll never forget the day I joined the army。

2。 先行词是表示地点的名词,在定从中作地点状语,关系代词用where; 其中注意表示抽象概念的地点名词,如,situation、stage、degree、point等表示方面或程度时,也需用where

eg。 This is the village Uncle Wang once lived。

They have reached the point they have to separate with each other。

He’s got himself into a dangerous situation he is likely to lose control over the plane。

3。 先行词是reason,在定从中作原因状语,关系代词用why

eg。 I don’t know the reason he was late。

None of us know the reason Tom was absent from the meeting。

4。引导定语从句的关系副词也能够用“适当介词 + which”来代替。

eg。 October 1, 1949 was the day when = the People’s Republic of China was founded。

This is the factory where(= we worked a year ago。

I don’t believe the reason why (= he was late for school。

Ⅳ。 关系代词that & which的区别:

⒈ 只用that的状况

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的状况:

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 inmy father lived last year。

Ⅴ。 as引导定语从句时的用法(as 相当于that & which)

① as引导限制性定语从句通常用于the same … as, such … as结构中。

eg。 This is the same book I lent you。

Such machines are used in our workshop are made in China。

② as引导非限制性定语从句既可放在主句之前,也可放在主句之后,位置灵活,用来修饰整个句子。通常用下列句型:as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。

eg。 I expected, ]www.chayi5.com[he got the first place again in this mid-term examination。

Taiwan, we all know, belongs to China。

Ⅵ。 限制性定语从句和非限制性定语从句的主要区别:

限制性定语从句: 一般紧跟在先行词后面,不用逗号把从句与先行词分隔开来。使先行词的意思十分明确,成为特定的人或物,是句子中不可缺少的成分,少了它句子就会失去好处不能成立,或意思不清楚,不能说明问题。通常译为定语。

非限制性定语从句: 通常由逗号与句子其他成分隔开。只是对先行词作进一步的说明,没有它句子仍能成立,意思仍很清楚。通常译为并列的句子。

eg。 I was the only person in our office was invited。(去掉定语从句,意思就不完整)

Tom’s father, is over sixty, still works hard day and night。(整个句子可分成两句来翻译)

Ⅶ。 分隔定语从句

即先行词与关系代词、副词之间被介词短语,同位语,谓语等分隔开来。

此种定语从句,在选取关系词时,要注意找准先行词。

eg。 There is an expression in his eyes (I can’t understand。

I was the only person in my office was invited to the important ball。

I suggest you choose someone I think is very kind and friendly。

《电话号码》教案 篇三

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

认识特殊号码

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。
