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

1、Unit 24 What were they doing教學(xué)教案 教學(xué)目標(biāo) 知識(shí)目標(biāo)與要求 通過本單元教學(xué)，使學(xué)生初步學(xué)習(xí)和運(yùn)用過去進(jìn)行時(shí)態(tài)，描述在過去某一時(shí)刻或某一段時(shí)間內(nèi)正在進(jìn)行或發(fā)生的動(dòng)作。了解這個(gè)時(shí)態(tài)陳述句式、疑問句式的構(gòu)成以及與其連用的一些時(shí)間狀語。上述要求，應(yīng)落實(shí)在學(xué)生的口語練習(xí)和書面語練習(xí)中，學(xué)生應(yīng)能獨(dú)立完成練習(xí)冊上有關(guān)過去進(jìn)行時(shí)態(tài)各種形式的練習(xí)，正確率不低于70%。教師還可視學(xué)生情況，要求學(xué)生用第一人稱改寫第94課課文，并運(yùn)用自己組織的語言復(fù)述課文。 教學(xué)重點(diǎn)與難點(diǎn) 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(xué)習(xí)過去進(jìn)行時(shí)態(tài)The Past continuous Tense I 情感態(tài)度目標(biāo) 通過本單元的教學(xué)使學(xué)生認(rèn)識(shí)到鄰里應(yīng)和睦相處。在日常生活中要時(shí)時(shí)處處注意自己的行為是否標(biāo)準(zhǔn)，是否符合公共道德。不要因?yàn)樽约翰痪杏谛」?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(xué)建議 教學(xué)內(nèi)容分析 本單元主要圍繞What were they doing這個(gè)話題來談?wù)撨^去的活動(dòng)，學(xué)習(xí)了過去進(jìn)行時(shí)態(tài)的構(gòu)成和根本用法及有關(guān)

3、的一些重點(diǎn)詞語。本單元還出現(xiàn)了一些近義詞，通過主題我們還學(xué)了一些日常用語和重點(diǎn)句型。在學(xué)習(xí)課文The man upstairs的同時(shí)，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(shí)間狀語從句。重點(diǎn)講到了過去進(jìn)行時(shí)態(tài)與時(shí)間狀語的關(guān)系，初步進(jìn)述了過去進(jìn)行時(shí)與一般過去時(shí)的區(qū)別。 重難點(diǎn)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(jìn)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(dòng)詞用，意思是“聽起來。它是知覺性動(dòng)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(gè)句型為find + it + 形容詞 + 動(dòng)詞不定式。句中的it是形式賓語，真正的賓語是后面的動(dòng)詞不定式。形容詞充當(dāng)賓語補(bǔ)足語補(bǔ)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(dòng)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(zé)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(shí)離開等場合，后面要具體說明請求對方原諒的內(nèi)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(rèn)。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(xué)過去進(jìn)行時(shí) 動(dòng)詞的過去進(jìn)行時(shí)表示過去某一時(shí)刻或某一時(shí)間內(nèi)正在進(jìn)行或發(fā)生的動(dòng)作。它的結(jié)構(gòu)為waswere+ 動(dòng)詞 -ing。老師在講授這一時(shí)態(tài)時(shí)不必泛泛而談它的語法功能，而要在與現(xiàn)在進(jìn)行時(shí)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(jìn)行時(shí)入引出過去進(jìn)行時(shí)，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(jìn)行時(shí)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(fù)習(xí)現(xiàn)在進(jìn)行時(shí)的結(jié)構(gòu)，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(xué)生在這些句子中都含有過去進(jìn)行時(shí)。老師與學(xué)生一起進(jìn)行分析比擬，歸納出過去進(jìn)行時(shí)的結(jié)構(gòu)和用法，及與現(xiàn)在進(jìn)行時(shí)的區(qū)別。 還可以根據(jù)實(shí)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(dòng)詞等局部成為后兩句，使學(xué)生對時(shí)態(tài)的變化有較深刻的印象。一旦學(xué)生理解了這兩個(gè)時(shí)態(tài)的不同概念，便可開始操練。讓學(xué)生把現(xiàn)在進(jìn)行時(shí)變?yōu)檫^去進(jìn)行時(shí)。 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(rèn)的答語答復(fù)。這樣操練的目的是訓(xùn)練語言的準(zhǔn)確性。 在教學(xué)中，要向?qū)W生說明：過去進(jìn)行時(shí)常常與過去某一特定時(shí)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(shí)行時(shí)的句子不帶時(shí)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(shí)間狀語是the next evening. 2利用圖片或動(dòng)作表演進(jìn)行教學(xué) 教師展示給學(xué)生一些事情正在發(fā)生的圖片，讓學(xué)生描述圖片中的人或物那時(shí)正在干什么比方給下面的圖片讓學(xué)生描述： T:
