一、整體設計思路、指導依據說明
《新課程標準》強調英語課程必須面向全體學生,要從學生的學習興趣和生活經驗出發,倡導體驗、實踐、參與、合作與交流的學習方式和任務型的教學途徑,發展學生的綜合語言運用能力,激發學生學習英語的興趣,幫助學生建立學習的成就感和自信心。語法教學是高中英語教學的重要組成部分,時態是高中學生必須掌握的語法內容,而現在完成進行時又是近五年來高考考查的重點。高中二年級第二學期模塊8第5單元Learning about language部分中的discovering useful structures部分主要是圍繞現在完成進行時展開的。基于以上三個方面,這堂語法課遵循二語習得的理論和中國學生的語言認知規律,變傳統的接受式教學法為“發現——體驗——探究——合作”式教學法,即以4P語法教學(preparation, presentation, practice, production)組織課堂,主張課堂教學應該指導學生在充分體驗語言材料的基礎上,即充分的語言信息輸入的基礎上,歸納有關語言知識,提高學生的語言技能。在設計思路上充分考慮到學生的生活經驗和興趣,為學生精心設置各種情景,通過一系列的任務活動,達到有效的語言輸出,即語法應用能力的培養。
二、教學背景分析
教學內容分析:在高中階段中,“現在完成進行時”是重點時態知識。備課前,筆者研讀了近五年的高考試題(2008-2012)發現現在完成進行時是近5年來高考時態考查新熱點。人教版新課標高中英語模塊1-7的課本并未涉及現在完成進行時的專門教學內容,而本節課學習的內容是人教版教材模塊8第5單元Learning about language部分中的一個課時。考慮到教學內容較多,既包含新詞匯的學習、鞏固和運用,又包含語法的講解,一節課很難落實教學目標,所以筆者對教材進行了重組,把learning about language 部分中的discovering useful structures單獨作為一個課時來學習現在完成進行時,以加強學生的理解和應用。著名語言學家Littlewood 曾經說過:“語言能力是具備交際能力的首要條件。因為一連串不合語法的句子很難達到交際的目的。好的交際能力必須要有扎實的語言知識作基礎”。因此本課語法教學將對掌握好這一單元語言知識及交際活動的順利進行,都起著支持的作用。故本節語法課的定位是:通過學生體驗、實踐、參與、合作與交流的方式進一步明晰“現在完成進行時”所表達的意義和句型結構特點以及現在完成進行時與現在完成時的區別。
學生情況分析:全班學生的基礎知識扎實,學習能力強。大部分同學學習英語的興趣較高。對于“現在完成進行時”,學生在平時做題時有所接觸,僅僅是處于一般的了解階段,因為學生更熟悉現在完成時,所以經常混淆現在完成時和現在完成進行時。而人教版教材在模塊8之前幾乎沒有專門涉及到現在完成進行時的教學內容,所以學生對平時練習時所見到的“現在完成進行時”理解不深刻,還不能準確清楚的說明現在完成時與現在完成進行時的區別。個別學生有時態的概念,但運用時仍然無法準確使用現在完成時和現在完成進行時。高二學生思維活躍,敢于提出不同見解。兩年的高中英語學習,使學生儲備了一定的詞匯和英語知識,能較好地展開話題討論,各抒己見。筆者采取多媒體輔助教學,創設多種語境,激發學生交流和學習的興趣,使他們始終處于主動的思考、探究和創造的狀態中,創設充滿活力的課堂氣氛。
三、教學目標分析
1.通過觀察例句,全班學生能夠說出現在完成進行時的構成形式;
2.通過完成本節課所設置的語言任務,全班學生能夠準確地應用現在完成進行時造句和翻譯;
3.通過本節課的學習,全體學生能夠說出現在完成時與現在完成進行時的區別;
4.觀察圖片和觀看新聞視頻片段,全班學生能夠運用現在完成進行時來描述見聞;
5.幫助學生對學習語法產生濃厚興趣,關注國內時事,主動積極地幫助身處困境的人,有用英語表達自己觀點和想法的欲望。
四、教學重點、難點分析
教學重點:
1.現在完成進行時的構成形式及其功能。
2.現在完成進行時在各種語境中的使用。
3.現在完成進行時與現在完成時的區別。
教學難點:
1.觀察和對比在具體語境中準確使用現在完成進行時。
2.觀察,歸納并總結出現在完成進行時與現在完成時的區別。
五、教學過程設計
步驟1:Preparation教師呈現四個含有現在完成進行時的句子。(1 min)
T: I have been teaching English in a high school since I graduated from the college.
I have been teaching English in a high school for seven years.
Hengshui High School has been attracting many students to study here.
How long have you been studying in Hengshui High School?
S: I have been studying in Hengshui High School for 2 years.
設計意圖:以教師自我介紹的方式引入易于激發學生的好奇心和求知欲,所呈現的現在完成進行時的四個例句生動具體,易于學生理解。師生通過兩個結合現在完成進行時的情境充分了解彼此,激發了學生的興趣,為學生通過觀察得出結論創造條件,也為下一步的任務奠定基礎。
步驟2:教師呈現人物描述,學生猜測班級的同學進行猜謎游戲。(3 mins)
T: (1) ______ has been showing interest in Kobe.
(2) ______ has been paying attention to the current affairs at home and abroad.
(3) ______ has been losing weight.
(4) ______ has been cycling to school every day.
(5) ______ has been suffering from English.
(6) _____ has not been taking notes in English class.
Ss: XX has been showing interest in Kobe; XX has been paying…
設計意圖:以班級的學生特點、興趣、愛好創設語境,所呈現的六個例句和學生生活緊密相連,易于與學生產生良好的互動,進一步激發學生學習本課內容的興趣。語言學習是枯燥的,學生在長時間的語言學習中,往往感到厭倦。根據學生的認知規律和表現欲強的特點,也為了給部分不愿參與語言學習的學生以足夠的動力,在課堂中適時的運用游戲能刺激學生思維。在游戲中體驗語法讓學生明白語言學習實際上是快樂的。
步驟3:Presentation學生歸納出現在完成進行時的構成方式。(1 min)
T: According to the above sentences, what kind of tense is used in the sentences?
S: The present perfect continuous tense.
T: Would you please tell everyone the form of the tense?
S: have/has+been+doing
設計意圖:學生通過觀察例句來總結歸納出現在完成進行時的構成形式。本節課主題生成并為下一個任務的進行提供基礎。
步驟4:Practice學生根據所給圖片及詞匯運用現在完成進行時造句。(3 mins)
T: Since we have known the present perfect continuous tense, now please make up sentences according to the given pictures and words, using the present perfect continuous tense.
(1) Let the workers sleep for a while because…(rescue the injured, for 24 hours nonstop)
S: …they have been rescuing the injured for 24 hours nonstop.
(2) President Xi has delivered the “Chinese dream” of national renewal and… (the Chinese people, try ones best, realize)
S: …the Chinese people have been trying their best to realize their dream.
(3) (Doctors, find a cure, H7N9)
S: Doctors have been trying to find a cure to defeat H7N9.
設計意圖:學生得出現在完成進行時的構成形式后進行及時練習,同時結合2013年國內重大時事,如“H7N9”的蔓延與傳播,“中國夢”的提出和2013年4月20日的雅安地震來設置現在完成進行時的語境。讓學生能夠充分地體會到現在完成進行時的功能和意義,也對學生進行了情感教育,讓他們關注時事,明白學習語言是為了在生活中使用。
步驟5:學生根據所給情境來選擇最佳答案。(2 mins)
T: In the past, you have learnt about the present perfect tense, now its your turn to make a choice for the following contexts.
Which sentence, A or B fits each situation bes?
(1)You want to find out why someone
is late.
A. What have you been doing?
B. What have you done?
(2)You want to talk about your success
in your golf training program.
A. Ive been playing today.
B. Ive played for six hours today.
(3)You want to complain about your
garage.
A. Theyve been repairing my car for
over a week.
B. Theyve repaired my car.
答案: A; B; A
設計意圖:通過提供三個具體的情境讓學生選擇恰當選項來初步感受現在完成時和現在完成進行時的差異。引導學生觀察三個語境,讓學生找出“why”,“success”,“complain”等關鍵詞并初步總結出現在完成進行時的表意功能。
步驟6:學生根據對話主要內容來補全對話。(4 mins)
T: Now, you are required to complete the dialogue with the given statements.
Dad: Come on, Julie. Have a break. Have a cup of tea. What have you been doing?
Julie: (taking the tea) Thanks, Dad. 1 ______. The old one moves when I sit on it.
Dad: Your bike looks good. Whats happened to the front wheel?
Julie: 2______. I havent quite finished yet. Dad, you look very tired. 3 ______?

E. And Ive put the new tyre on.
F. Ive just finished this report.
G. Ive put the new saddle on.
H. Ive printed it out.
答案:D, A, B, C, F, H, G, E
設計意圖:通過將對話補充完整的形式讓學生在一個完整的情境里進一步體驗現在完成時和現在完成進行時的區別。讓學生分角色朗讀對話來進一步感受兩種時態的運用差異。
步驟7:Summary A 學生根據三個練習的內容總結現在完成時與現在完行時的各自特點。教師引導學生運用比喻的方式理解現在完成時與現在完成進行時的差異。(6 mins)
T: From the dialogue, I know that you begin to sense the differences of the present perfect and present perfect continuous tense, now lets compare the two tenses. First, lets say something about the present perfect since we are familiar with it.
S: The present perfect tense is mainly used to express result or finished actions. One example is “Ive just finished this report.”
T: Well, Lets compare “Ive been putting a new tyre on.” / “And Ive put the new tyre on.”
“Ive been writing a report.” / “Ive just finished this report.”
“Ive been putting a new saddle on". / "Ive put the new saddle on.”
According to the sentences above, what are the differences between the present perfect and present perfect continuous tense?
S: The present perfect continuous tense is mainly used to talk about an activity and its consequences. One example is “Dad, you look very tired. Have you been working all afternoon?”
S: The present perfect continuous tense is also used to talk about a repeated or continuous activity that is still going on. One example is " Ive been putting a new tyre on. I havent quite finished yet.”
T: Based on your understanding of the differences of the two tenses, please try to fill in the chart below.
T: If I compare the present perfect tense to an aged man with achievements and regrets, then the present perfect continuous tense can be compared to…
S: In my opinion, the present perfect continuous tense can be compared to an aggressive youth with passion and efforts.
設計意圖:基于前面的練習,要求學生以小組為單位進行觀察,分析和對比,用簡潔的話語概括現在完成時和現在完成進行時的特點;通過一個生動的比喻來幫助學生準確識記兩種時態的差異。
步驟8:Production 學生根據題目選出最佳選項。(3 mins)

步驟9:Summmary B 學生根據所提供的練習總結歸納典型的現在完成進行時的時間狀語。(2 mins)
T: In the above six sentences, can you find the time adverbials?
S: since 9 am.; every night over the last three months; this year; all the time; all afternoon; since her marriage to father.
設計意圖:學生通過主動觀察,在教師的點撥下,較好地歸納出現在完成進行時的典型時間狀語,避免了以往教師上語法課喋喋不休的講解,學生聽得昏昏欲睡的被動局面。現在完成進行時的一些標志性的時間狀語是解答此類試題的關鍵,同時也為為下一步任務做鋪墊。
