【設(shè)計原則】
1.小組合作學習與任務(wù)型教法結(jié)合
教學中運用小組討論和定點提問方式實施課堂活動。由復習一般疑問句開始,再進行定點式提問,再進行互改句式,進而導入新課語法,后采用小組學習和任務(wù)型教學相結(jié)合教學。
2.多元評價與競爭機制
在小組活動中開展小組競賽,導用競爭機制和課堂評價策略,加強自主學習和合作性學習,培養(yǎng)學生思維創(chuàng)意識。
【教學步驟】
一、溫故知新
由于各知識點之間有聯(lián)系,在講授新課時采用先復習前面的相關(guān)知識,既可做到知識鞏固,又可起橋梁作用。
1.Step 1 Revision 復習一般疑問句的構(gòu)成
將下列句子改為一般疑問句:
He is a hard-working boy.
They were busy doing their homework.
2.方法指引
(1)Rules:如果句中有be動詞,將be動詞移到句首。
The boy absorbed in the novel can play the piano.
Students should concentrate on their studies.
(2)如果句中有情態(tài)動詞,將情態(tài)動詞移到句首。
Tom has learned 2000 English words by now.
Her brothers have been to Paris twice.
(3)如果是將來時和完成時,則將結(jié)構(gòu)詞will、would、has、have、had移到句首。
They often walk to school.
Lucy got up late yesterday.
(4)如果行為動詞在句中直接作謂語,則要在句首添加助動詞do、does、did,且原謂語動詞要改為原形。
二、承前啟后
鞏固練習完成之后,我們依托學生先期的預習、老師的前期任務(wù)布置,開始新知識的學習,主要借助小組學習、教師任務(wù)型安排來開展教學工作。
1.小組提煉
Step 2 New lesson
Task 1 Read the sentences from text A Unit 3 世紀英語 綜合教程
(1)So impressed was Ray Kroc with the brother approach that he became their national franchise agent...
(2)Only if you ask many different questions will you acquire all the information you need to know.
2.明確任務(wù)
部分倒裝:部分倒裝是指將謂語的一部分如be動詞、情態(tài)動詞、結(jié)構(gòu)詞倒裝至主語之前。如果句中的謂語沒有be動詞、情態(tài)動詞、結(jié)構(gòu)詞,則需添加助動詞do,does或did,并將其置于主語之前,同時把原謂語動詞改為原形。
簡易記憶:部分倒裝:提前詞+一般疑問句
3.小組學習
Task 2 哪些詞提前置于句首就要使用部分倒裝?
(1)句首為否定或半否定的詞或短語,如never,seldom,hardly,scarcely,barely,rarely,nowhere,not,at no time, in no way, by no means,in no case(絕不)...
Never have I seen such a performance.
Nowhere else will you find the answer to this question.
(2)幾個否定詞提前的特殊句型。
簡易記憶:not until +時間點/ 從句 +部分倒裝主句
直到10點他才吃早餐。
直到做完作業(yè)她才睡覺。
no sooner...than...,hardly / scarcely...when:一…就,剛…就
No sooner had Black got home than the phone rang.
Hardly had she gone out when a student came to visit her
注意:前倒后不倒,即主句倒裝,從句不倒裝主句用過去完成時,從句用一般過去時。
Can you find an easier way to master the structure?
簡易記憶:no sooner had sb. done sth. than sb. did sth.
hardly /scarcely had sb. done when sb. did sth.
No sooner Tom (enter)the office than it rained heavily.
Hardly Mr. Green (arrive)when he complained.
so/such...that句型中的so/such位于句首時,需倒裝。
So+adj./adv.+部分倒裝句子that+陳述語序句子
He is so kind that we all like him.
So kind that we all like him.
(3)only所修飾的副詞、介詞短語或狀語從句放在句首時,部分倒裝。
Only when he is seriously ill does he ever stay in bed.
Only then did I realize the importance of English.
(4)由連接詞so,neither,nor引導的句子作部分倒裝。
(5)在if引導的非真實條件句中,如有助動詞had,should或were時,可以省略if,進行倒裝,如:
Should anyone call, tell him to wait for me here.
(=If anyone should call, tell him to wait for me here.)
(6)as引導的倒裝句。
(7)在某些表示祝愿的句型中:
May you all be happy. Long live the king! May God bless you.
三、評價與競爭
由同學們個性化學習和小組合作之后,基本懂得了部分倒裝的句式特點,由此總結(jié)出其簡記法:提前詞+一般疑問句。為了實現(xiàn)教學結(jié)果,增加了小組競賽和整體評價機制。
1.小組競賽
組內(nèi)成員討論。小組進行競賽的形式,在運用鞏固語法的同時,能夠激發(fā)學生的合作意識與競爭意識,也能使課堂氣氛活躍起來。
2.evaluation
(1)What have we learned today?
(2)My favorite part in this lesson is
(3)I think the group with the best performance is
Ask students to assess what they have learned and how good their performance is in this lesson.
本教學設(shè)計以實效為主,注重知識遷移、新知識體系的建立,利用學生自主學習和小組合作探究,采用任務(wù)型教學,多種方式下找準部分倒裝句的句式特點,總結(jié)其方法,促進學生們高效、順利掌握相關(guān)知識。并采用課堂評價以激勵學生的學習興趣,達到獎勤罰懶功效,客觀上約束大家學習,并配合競爭機制,做好個性化學習,個性化提升。
