定語從句課件篇一
一、設計背景
1． 初步掌握及運用定語從句，如讓學生用定語從句來完成對人物喜歡的人物進行描述，如I like music that I can dance to. She is the only one who’s studying French.等。
2． 本課的學習任務就是能初步掌握及運用定語從句，為了使學生順利地完成教學任務，教師以學生為主體，為學生設計了幾個以他們的認知水平出發的符合生活實際的他們感興趣的一環扣一環的子任務，每個子任務緊緊圍繞總任務展開，再深入，在一個一個完成任務的活動中培養學生的能力。
二．教學目標
（1）語言目標：能用定語從句較自如地描述及談論人和物。在活動中訓練學生的聽力，口頭表達能力，培養學生的觀察，想象和創造力。
（2）情感目標：促進同學間積極合作交流，發展同學間的友誼 。
2．教學方法 ：多媒體的運用能創設真實的語言情景，學生也很感興趣，極大地鼓動了學生學習英語的積極性，而且呈現在課堂上能使教學更生活化，也更直觀和具體。
三、教學方法
以學生為主體，用多媒體輔助教學，通過幫助學生理解、歸納、總結、討論等方式學習定語從句，由于本節課是學生第一次系統學習定語從句，要達到讓學生初步掌握定語從句這一目的。
四、學法指導、自主學習、合作學習
五、教學過程
第一環節： 觀察以下例句：
1.The red pen is broken.
2.The pen on the desk is broken.
3.The pen that I bought yesterday is broken.
導入：通過對定語的理解，導入定語、定語從句的概念，定語：用來修飾名詞或代詞的詞、短語或句子，當修飾詞是一個句子時被稱為定語從句。通常置于它所修飾的詞之后，這種被修飾的詞叫做先行詞，引導定語從句的關聯詞為關系代詞和關系副詞，關系代詞在定語從句中可用作主語、賓語、定語等，關系副詞在定語從句中只用作狀語。
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.
You can’t wake up a person who pretends to sleep.
He who can’t get to the Great Wall is not a true man.
I like musicians who play different kinds of music.
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 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.
得出結論1)當先行詞是物時
a. 關系代詞代替先行詞在定語從句中作主語時，用which/that引導，且不能省略.b. 關系代詞代替先行詞在定語從句中作賓語時，用which/that引導，且可以省略.
2)當先行詞是人時
a. 關系代詞代替先行詞在定語從句中作主語時，用who/that引導，且不能省略.b. 關系代詞代替先行詞在定語從句中作主語時，用who/that/whom引導，且可以省略.
第二環節：在學生對定語從句有了初步的了解后，創設情境，學以致用，讓學生分組活動，根據多媒體呈現的情境，有創造性地造句：
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.
It’s an animal that/which has long nose and big ears.
It’s an animal that/which I like very much.
第三環節：在學生對一般的規律都把握好以后，把學生的易錯點和定語從句的考點呈現在屏幕上，讓學生仔細觀察并作出總結，該環節設計得很好，很好地訓練了學生的觀察能力和主動探究的能力，效果較好。
仔細觀察：你會發現什么？
1) I prefershoesthat are cool.
2) I likea pizzathat is really delicious.
3) I lovesingerswho are beautiful.
4) I havea friendwho plays sports.
學生觀察后得出的結論為：
who/that在定語從句中做主語時,謂語動詞的單復數應與先行詞保持一致。
第四環節：小節本堂課的內容
什么是定語？
什么是定語從句？
定語從句的結構是什么？
關系詞有幾重作用？
此環節讓學生對所學的知識加以升華，并在大腦里形成知識框架，把知識系統化。
第五五環節：鞏固練習---以檢查學生是否真正掌握本堂課的知識，實踐證明，學生掌握得很好。
第六環節：合作探究
留給學生的問題
1.如果先行詞既有人又有物，用什么關系詞？
2.如果先行詞是時間，用什么關系詞？
3.如果先行詞是地點，用什么關系詞？
4.關系詞whose怎么用？
通過此環節給學生留下思維拓展的空間，也為以后的學習做好鋪墊，體現學習的延續性。
課堂小結：通過例子讓學生總結定語從句的規律和特點，同時總結不同關系詞的用法。在這節課中，學生對定語從句這一語法項目有了不同程度的鞏固和深化。
六、課后反思：
提倡任務型教學活動，是為了讓學生們在教師的指導下，通過感知，體驗，實踐，參與合作等方式，力求最大限度地把語言能力的培養落實到教學過程的每一個環節，逐步實現預定的任務目標并感受成功。我在這堂課的設計里要求自己新穎別致，突出故事的完整性，要有一氣呵成的感覺，重點落實，定語從句自始至終貫穿每個環節，活而不亂，生動有趣，貼近生活，氣氛活躍。能發揮學生們的主體互動性和能動性，在完成任務的過程中能積極參與。課后感覺任務型教學有所體現，學生們積極性高，參與面廣，訓練量較大，能初步運用定語從句。
但在教學過程中，我意識到：有個別學生基礎太差，雖在課堂中他們也積極參與，但有時很盲目，甚至不知道老師和同學們在進行什么內容，從他們的目光和神態中，我了解到他們對知識的渴求，我暗自告訴自己，一定要幫助他們，這很難，但一定要堅持，決不放棄。
定語從句課件篇二
Ⅰ. 定義
定語從句，起形容詞的`作用，在句中常用來修飾名詞或代詞。被修飾的詞稱為先行詞,引導定語從句的詞稱為關系詞, 關系詞的作用一是放在先行詞與定語從句中間起引導作用;二是在意義上代替先行詞,并在從句中充當一個成分。其中關系代詞：who, whom, whose, which, that, as；關系副詞：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 come when people will be able to breathe clean air in cities.
Ⅱ. 關系代詞
1.先行詞是人，作主語，關系代詞用who, that
eg. He is a man（ ） never leaves today’s work till tomorrow.
The boy ( ) is standing there is my cousin.
2. 先行詞是人，作賓語，關系代詞用 whom, who, that,
eg. Here is the man ( ) you’ve been expecting to meet.
The man ( ) you met yesterday is Mr. Smith.
3. 先行詞是物，作主語，關系代詞用which, that
eg . The train （ ） has just left is for Guangzhou.
Children like to read books ( ) have wonderful pictures.
4. 先行詞是物，作賓語，關系代詞用which, that,或省略
eg. The book ( ) you borrowed yesterday is really interesting.
The pen ( ) my uncle gave me is missing.
5. 先行詞是人、物，作定語，關系代詞用whose
eg. He is the professor ( ) name was Jackson.
China, （ ） population is the largest in the world, is developing very fast.
Ⅲ. 關系副詞
1.先行詞是表示時間的名詞，在定從中作時間狀語，關系代詞用when
eg. I can’t remember the date ( ) he went abroad.
I’ll never forget the day ( ) I joined the army.
2.先行詞是表示地點的名詞，在定從中作地點狀語，關系代詞用where; 其中注意表示抽象概念的地點名詞，如，situation、stage、degree、point等表示方面或程度時，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. 先行詞是reason，在定從中作原因狀語，關系代詞用why
eg. I don’t know the reason ( ) he was late.
None of us know the reason ( ) Tom was absent from the meeting.
4.引導定語從句的關系副詞也可以用“適當介詞 + which”來代替。
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. 關系代詞that & which的區別:
⒈ 只用that的情況
① 先行詞為all, everything, anything, nothing, little, much等不定代詞時。
eg. There is nothing ( ) can prevent him from doing it.
② 先行詞被any, only, few, no, very, little 等修飾時。
eg. This is the very book ( ) I’m looking for.
③ 先行詞被形容詞最高級或序數詞修飾時。
eg. The first place ( ) they visited in Guilin was Elephant Trunk Hill.
This is the best film ( ) I have ever seen.
④ 先行詞既有人又有物時。
eg. He talked about things and persons ( ) they remembered in the school.
⑤ 先行詞被the only, the very修飾時。
eg. Mr. Smith is the only foreigner ( ) he knows.
⑥ 句中已有who或which,為了避免重復時。
eg. Who is the man ( ) is standing beside Tom?
⒉ 不能用 that的情況：
① 引導非限制性定語從句；
eg. He had failed in the maths exam , ( ) made his father very angry.
② 介詞 + 關系代詞。
eg. This is the room in（ ） my father lived last year.
Ⅴ. as引導定語從句時的用法(as 相當于that & which)
① as引導限制性定語從句通常用于the same … as, such … as結構中。
eg. This is the same book ( ) I lent you.
Such machines ( ) are used in our workshop are made in China.
② as引導非限制性定語從句既可放在主句之前，也可放在主句之后，位置靈活，用來修飾整個句子。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, he got the first place again in this mid-term examination.
Tai·wan, ( ) we all know, belongs to China.
Ⅵ. 限制性定語從句和非限制性定語從句的主要區別:
限制性定語從句: 一般緊跟在先行詞后面,不用逗號把從句與先行詞分隔開來。使先行詞的意思十分明確,成為特定的人或物,是句子中不可缺少的成分,少了它句子就會失去意義不能成立,或意思不清楚,不能說明問題。通常譯為定語。
非限制性定語從句: 通常由逗號與句子其他成分隔開。只是對先行詞作進一步的說明,沒有它句子仍能成立,意思仍很清楚。通常譯為并列的句子。
eg. I was the only person in our office （ ） was invited.（去掉定語從句，意思就不完整）
Tom’s father, （ ） is over sixty, still works hard day and night.（整個句子可分成兩句來翻譯）
Ⅶ. 分隔定語從句
即先行詞與關系代詞、副詞之間被介詞短語，同位語，謂語等分隔開來。
此種定語從句，在選擇關系詞時，要注意找準先行詞。
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.
