（初二英語教案）Unit 24 What were they doing-－教學教案

1、Unit 24 What were they doing教學教案 教學目標 知識目標與要求 通過本單元教學，使學生初步學習和運用過去進行時態(tài)，描述在過去某一時刻或某一段時間內正在進行或發(fā)生的動作。了解這個時態(tài)陳述句式、疑問句式的構成以及與其連用的一些時間狀語。上述要求，應落實在學生的口語練習和書面語練習中，學生應能獨立完成練習冊上有關過去進行時態(tài)各種形式的練習，正確率不低于70%。教師還可視學生情況，要求學生用第一人稱改寫第94課課文，并運用自己組織的語言復述課文。 教學重點與難點 1句型：1Its quite a nice picture.2)Im sorry to trouble you.

2、3) to find it difficult to do sth. 4) Would you please not do this 2語法：學習過去進行時態(tài)The Past continuous Tense I 情感態(tài)度目標 通過本單元的教學使學生認識到鄰里應和睦相處。在日常生活中要時時處處注意自己的行為是否標準，是否符合公共道德。不要因為自己不拘于小節(jié)而影響別人，給他人帶來麻煩。萬一鄰里之間發(fā)生矛盾要通過協(xié)商的方法加以解決，以防發(fā)生不必要的沖突。 教學建議 教學內容分析 本單元主要圍繞What were they doing這個話題來談論過去的活動，學習了過去進行時態(tài)的構成和根本用法及有關

3、的一些重點詞語。本單元還出現(xiàn)了一些近義詞，通過主題我們還學了一些日常用語和重點句型。在學習課文The man upstairs的同時，我們得到了教育和啟發(fā)，課文告訴我們在日常生活中要注意公共道德，不要因自己而影響他人，給別人帶來不必要的麻煩。另外本單元提到和出現(xiàn)了時間狀語從句。重點講到了過去進行時態(tài)與時間狀語的關系，初步進述了過去進行時與一般過去時的區(qū)別。 重難點分析 1. get on well with 1在本單元中的意思是“與相處融洽。例如： How are you getting on with your English teacher Im getting on well with

4、him 2也可以作“某事進展情況如何的意思講。例如： My son is getting on well with his work. He feels very happy. 2. sound l在本單元中作名詞用，意思是“聲音。例如： Light travels faster than sound. We can see light first. 2還可以作動詞用，意思是“聽起來。它是知覺性動詞，后面須用形容詞作表語。例如： Does this sentence sound right I think its right. 3. He found it very difficult to

5、sleep and he was rather angry with the man upstairs 1這個句型為find + it + 形容詞 + 動詞不定式。句中的it是形式賓語，真正的賓語是后面的動詞不定式。形容詞充當賓語補足語補充說明it。這樣就防止了頭重腳輕的現(xiàn)象，使句子平穩(wěn)。例如： I found it easy to work out the problem. I can do it by myself. 2適用于此句型的動詞還有think。例如： I think it very important to learn a few English words every day

6、I agree with you. 交際英語分析 1. I am sorry to trouble you. 1Sorry表示“事后的歉意，如失約、遲到，打攪別人或無法承諾，受到責備需要委婉地為自己辯白等，還可以表示失禮等之后的難過和懊悔。Im sorry后可接不定式、從句或與介詞 for/about搭配，也可采用Im sorry + but + 從句but在這兒表示客氣，故不譯成“但是的句型。例如： I am sorry Im late Im sorry, but I left your book in the room. 2Excuse me也可以表示“抱歉，常用于向陌生人請求幫助，請別人

7、讓路、問路、借東西。詢問，打斷他人發(fā)表不同意見，請求暫時離開等場合，后面要具體說明請求對方原諒的內容。例如： Excuse me. Can you tell me the time I am sorry, but I dont have a watch 3類似表“歉意的句型還有：Im afraid that例如：I am afraid that Im late 4對“抱歉的答語常用的有：Never mind/ Not at all./ I doesnt matter./ Thats nothing./Please dont worry. / Forget it./ No problem 2.

8、Would you please not do this 1Would you please(not).表示一種委婉、客氣的請求別人干某事或不干某事，其答語可以是：Certainly./Yes, all right./ Id glad to./With great pleasure./OK等表了肯定。I am sorry I cant./ Im afraid I cant do it./ Certainly not等表示否認。例如： 123456下一頁 1Would you please help me Certainly 2Would you please not make a noise

9、Well, of course 2類似表示這種委婉請求的句型還有： Could you. . . Will you please. . . May I. . . Please. . . 例如： Could you carry it for me Will you please help me May I borrow your bike Please wait for your turn. 教學過去進行時 動詞的過去進行時表示過去某一時刻或某一時間內正在進行或發(fā)生的動作。它的結構為waswere+ 動詞 -ing。老師在講授這一時態(tài)時不必泛泛而談它的語法功能，而要在與現(xiàn)在進行時和過去式的比擬中

10、逐步理解和掌握。 1呈現(xiàn)第93課由現(xiàn)在進行時入引出過去進行時，這是傳統(tǒng)的有效方法。 老師用幻燈或直接在黑板上寫出一些含有現(xiàn)在進行時的句子。例如： 1. The teacher is talking with some students in the classroom, now. 2. They are listening to music in the next room, now. 3. Whats Li Lei doing Hes drawing a picture on the blackboard. 4. What are your parents doing They are wa

11、tching TV. 5. My English teacher is writing a novel these days. 通過這些句子復習現(xiàn)在進行時的結構，isare+ v-ing的用法。接下來用幻燈再打出如下句子： 1. The teacher was talking with some students in the classroom this time yesterday. 2. They were listening to music in the next room at ten oclock yesterday. 3. What were your parents doin

12、g when your brother came back They were watching TV. 4. What was Li Lei doing when the teacher came in He was drawing a picture on the wall. 5. My son was learning English in Australia last autumn. 告訴學生在這些句子中都含有過去進行時。老師與學生一起進行分析比擬，歸納出過去進行時的結構和用法，及與現(xiàn)在進行時的區(qū)別。 還可以根據實際情況如下問答： T: What are you doing now S

13、: I am / We are having an English lesson. T: What were you doing at this time yesterday S: I was / We were having a Chinese lesson. 把前兩句寫在黑板上，然后改變謂語動詞等局部成為后兩句，使學生對時態(tài)的變化有較深刻的印象。一旦學生理解了這兩個時態(tài)的不同概念，便可開始操練。讓學生把現(xiàn)在進行時變?yōu)檫^去進行時。 接下去作問答操練。What were you / was he / doing at this time yesterday I / He / She was h

14、avingWe / They were havingWere you / they havingWas he / she having 并用肯定或否認的答語答復。這樣操練的目的是訓練語言的準確性。 在教學中，要向學生說明：過去進行時常常與過去某一特定時間的狀語連用，如本單元所列舉的last night, last Saturday, at ten oclock yesterday morning, at noon yesterday, 還有at that time, (at ) this time yesterday等。但是，有些過去時行時的句子不帶時間狀語，而是由上下文暗示，例如文中的He was feeling very tired. He was just falling asleep when there was a loud knock at the door. 從上下文可看出時間狀語是the next evening. 2利用圖片或動作表演進行教學 教師展示給學生一些事情正在發(fā)生的圖片，讓學生描述圖片中的人或物那時正在干什么比方給下面的圖片讓學生描述： T:
