定语从句教案

1、定语从句教案定语从句教案 定语从句教案（一）： 一、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，口头表达潜力，培养学生的观察，想象和创造力。 （2）情感目标：促进同学间用心合作交流，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用心性，而且呈此刻课堂上能使教学更生活化，也更直观和具体。 二、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

2、whos 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贴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潜力。 三、学法指导、自主学习、合作学习 四、教学方法 以学生为主体，用多媒体辅助教学，透过帮忙学生理解、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，要到达让学生初步掌握定语从句这一目的。 五、教学过程 第一环节： 观察以下例句： 1。The red pen is b

3、roken。 2。The pen on the desk is broken。 3。The pen that I bought yesterday is broken。 导入：透过对定语的理解，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 fri

4、ends who are different from me。 He is the only one who is studying French。 Be careful of the person who doesnt speak and the dog that doesnt bark。 You cant wake up a person who pretends to sleep。 He who cant get to the Great Wall is not a true man。 I like musicians who play different kinds of music。

5、 Another that he found very difficult is grammar。 The other day， my friends and I talked about the rules that we have in school。 Being a profeional 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

6、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whichthat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whichthat引导，且能够省略。 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whothat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whothatwhom引导，且能够省略。 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 whothat who i

7、s a boy。 who is very shy。 who writes his own songs。 who has a song calledQinghuaci。 Who I like best。 Its an animal thatwhich is very strong。 Its an animal thatwhich has long nose and big ears。 Its an animal thatwhich 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此刻屏幕上，让学生仔细观察并作出总结，该环节设计得很好，

8、很好地训练了学生的观察潜力和主动探究的潜力，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。 3) I lovesingerswho are beautiful。 4) I havea friendwho plays sports。 学生观察后得出的结论为： whothat在定语从句中做主语时，谓语动词的单复数应与先行词持续一致。 第四环节：小节本堂课的资料 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

9、升华，并在大脑里构成知识框架，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。如果先行词是时光，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怎样用？ 透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：透过例子让学生总结定语从句的规律和特点，同时总结不一样关系词的用法。在这节课中，学生对定语从句这一语法项目有了不一样程度的巩固和深化。 六、课后反思： 提倡任务型教学活动，是为了让学生们在教师的

10、指导下，透过感知，体验，实践，参与合作等方式，力求最大限度地把语言潜力的培养落实到教学过程的每一个环节，逐步实现预定的任务目标并感受成功。我在这堂课的设计里要求自我新颖别致，突出故事的完整性，要有一气呵成的感觉，重点落实，定语从句自始至终贯穿每个环节，活而不乱，生动搞笑，贴近生活，气氛活跃。能发挥学生们的主体互动性和能动性，在完成任务的过程中能用心参与。课后感觉任务型教学有所体现，学生们用心性高，参与面广，训练量较大，能初步运用定语从句。 但在教学过程中，我意识到：有个别学生基础太差，虽在课堂中他们也用心参与，但有时很盲目，甚至不明白老师和同学们在进行什么资料，从他们的目光和神态中，我了解到他

11、们对知识的渴求，我暗自告诉自我，必须要帮忙他们，这很难，但必须要坚持，决不放下。 定语从句教案（二）： 。 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

12、 miing。 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。 。 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 todays work till tomorrow。 The boy is sta

13、nding 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 youve 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

14、which， that，或省略 eg。 The book you borrowed yesterday is really interesting。 The pen my uncle gave me is miing。 5。 先行词是人、物，作定语，关系代词用whose eg。 He is the profeor name was Jackson。 China， population is the largest in the world， is developing very fast。 。 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 cant

15、 remember the date he went abroad。 Ill 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。 Hes g

16、ot 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 dont 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 Peoples

17、 Republic of China was founded。 This is the factory where(= we worked a year ago。 I dont believe the reason why (= he was late for school。 。 关系代词that which的区别: 只用that的状况 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。 先行词被any， only， few

18、， no， very， little 等修饰时。 eg。 This is the very book Im looking for。 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。 先行词既有人又有物时。 eg。 He talked about things and persons they remembered in the school。 先行词被the only， the very修饰

19、时。 eg。 Mr。 Smith is the only foreigner he knows。 句中已有who或which，为了避免重复时。 eg。 Who is the man is standing beside Tom? 不能用 that的状况： 引导非限制性定语从句; eg。 He had failed in the maths exam ， made his father very angry。 介词 + 关系代词。 eg。 This is the room inmy father lived last year。 。 as引导定语从句时的用法(as 相当于that which)

20、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。 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，

21、he got the first place again in this mid-term examination。 Taiwan， we all know， belongs to China。 。 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。

22、 I was the only person in our office was invited。(去掉定语从句，意思就不完整) Toms father， is over sixty， still works hard day and night。(整个句子可分成两句来翻译) 。 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 expreion in his eyes (I cant understand。 I was the only person in my office wa

35、（而在一个句子中充当整个句子的宾语的句子叫做宾语从句） 如：I love this English teacher whose eyes are blue。 (定语从句) 我爱眼睛是蓝色的这位英语老师 I dont know (宾语从句) 我不明白你怎样才能到达那个公园。 2。 【考查点】被定语从句修饰的名词或代词叫先行词。 如：A friend is someone who says， What! You too? I thought I was the only one! A Wechat (微信) is an invention which can help people talk to

36、 friends， share photos， ideas and feeling freely。 知识点2：定语的关系词关系代词 1。【考查点】既能指物也能指人的关系代词 that，whose。 如： I like this person that has 3 story books。 (先行词是人person) 先行词是物book) （先行词是teacher） 先行词是dog) 2、【考查点】只能用来指代人的关系词who， whom。 如：Is he the man who wants to see you? He is the man whom that I saw yesterday。

37、 3、【考查点】只能指代物的关系词which。 如：A prosperity which had never been seen before appears in the countryside。 4、【考查点】关系词在句子中充当的成分。 如：1、（whothat在从句中作主语） 他就是你想见的人吗？ 2、他就是我昨日见的那个人。（whomthat在从句中作宾语） 3、作宾语） which that在句中（ 农村出现了前所未有的繁荣。 4、（(只用作定语) 那人车坏了，大家都跑过去帮忙。 （注：当上题先行词指物时它还能够同of which互换） 如：Please pa me the book

38、 whose (of which) cover is green。 请递给我那本绿皮的书 知识点3：关系副词引导的定语从句 关系副词when， where， why可代替的先行词是时光、地点或理由的名词，在从句中作状语。 【考查点】关系副词when， where， why的含义相当于介词+ which结构，因此常常和介词+ which结构交替使用。 如： There are occasions when (on which) one must yield。 任何人都有不得不屈服的时候。 Beijing is the place where (in which) I was born。 北京是我

39、的出生地。 Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮忙他的理由吗？ 知识点4：关系词的选取取决于从句中的谓语动词 1。【考查点】 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就务必要求用关系代词；而不及物动词则要求用关系副词。 如： This is the mountain village where I stayed last year。 四、例题精析 【例题1】 【题干】Nearly all the streets are in straight lines， _ fro

40、m east to west。 Those _ run from north to south are called avenues。 A。 running; that B。 run; who C。 running; who D。 run; that 【答案】A 【解析】： 主语与run(延伸)是主动关系，所以用此刻分词。Those指街道，所以不用 来引导定语从句。 who而用that 【题干】Is this research center _ you visited the modern equipment last year? A。 where B。 that C。 the one tha

41、t D。 the one where 【答案】：D 【解析】：将疑问句改为陈述句：this research center is显然缺少先行词，务必加上代词the one来作先行词，又因定语从句不缺主语或宾语，所以用关系副词where。假若在this后加the，就选where，请想想这是为什么。 【题 干】 The treatment will continue until the patient reaches the point _ he can walk correctly and safely。 A。 when B。 where C。 which D。 whose 【答案】：B 【解析

42、】 因为表示阶段、程度、地步的the point在定语从句中作地点状语，所以用 语从句。 where引导定 【题干】 How did you get in touch with the travel agent， Robin?

46、的one前面使用了定冠词the，则the one就应视为先行词。 6。The factory _well visit next week is not far from here。 A。 where B。 to which C。 which D。 in which 【答案】C。 【解析】which是关系代词，在从句中作visit的宾语。其他几个答案都不能作宾语。 7。Great changes have taken place since then in the factory _we are working。 A。 where B。 that C。 which D。 there 【答案】 A

49、语从句的概念，定语从句的关系词，定语从句的先行词等。需要重点掌握的是定语从句的先行词和定语从句的关系词。此外，在初中阶段也会经常接触到定语从句关系代词和关系副词的选取，因此，这个考点也需要重点掌握。 近年中考对语法点的考查往往是与语境想结合，因此，同学在做题时要结合语境来分析题目，灵活地运用语法知识。 定语从句教案（四）： 教学目标： 1。学生能正确理解整个句子的意思 2。学生能掌握关系代词和关系副词的正确使用。 教学重难点： 定语从句中引导词（who， whose，whom， that ， which，when，where， why）的正确使用 教学过程： 例子导入： The girl is
