新人教版高一英語下 Unit 16 Scientists at workReading教案一、 教學(xué)背景分析1學(xué)生情況分析 本單元的設(shè)計與實施是建立在學(xué)生經(jīng)過高一上半學(xué)期新教材學(xué)習(xí)基礎(chǔ)之上。學(xué)生已經(jīng)逐步的適應(yīng)了在活動與任務(wù)中學(xué)習(xí)英語以及如何處理語言知識與活動開展的關(guān)系。并且，他們也已經(jīng)形成并培養(yǎng)了一定的小組合作學(xué)習(xí)及自主學(xué)習(xí)的能力。2. 單元背景分析 隨著科學(xué)技術(shù)的發(fā)展，各種各樣新的發(fā)明和發(fā)現(xiàn)都層出不窮。生活在這樣一個知識爆炸的年代，學(xué)生們更應(yīng)用心去體會并感受科技和發(fā)明創(chuàng)造者給生活帶來的變化，進而能聯(lián)想到他們平時所學(xué)的學(xué)科及知識，并用英語為媒介進行知識的整合與串聯(lián)。同時從另一個角度來說，科技進步的同時，我們的社會也產(chǎn)生了各種各樣的矛盾與爭論，因此如何正確的看待或處理這些問題，也成為廣大學(xué)生應(yīng)該了解并掌握的知識。通過學(xué)習(xí)偉人的事跡，走近科學(xué)家的精神世界，學(xué)習(xí)科學(xué)家為尋求真理的獻身精神，求是精神，樹立向上的學(xué)習(xí)和生活態(tài)度，培養(yǎng)學(xué)生高尚的情操。二、教學(xué)目標(biāo)分析語言知識詞匯：學(xué)習(xí)并使用一些與science 和scientists有關(guān)的詞匯。語法：進一步了解一詞多義現(xiàn)象與合成詞的構(gòu)成。功能：學(xué)習(xí)如何就某一事物給予別人指導(dǎo)與說明。話題：掌握有關(guān)實驗說明的話題表達以及如何從正反兩方面對某一話題進行分析討論。語言技能聽：在聽懂教師向?qū)W生講述實驗中注意事項基礎(chǔ)上，繼續(xù)學(xué)習(xí)并強化捕捉特定信息的能力，以及確定全文主要話題的概括能力。說：應(yīng)能在了解一定的現(xiàn)代科技發(fā)明基礎(chǔ)上，思考并學(xué)習(xí)如何對一種新的事物進行描述。同時能與他人進行交流，敘述事物的利與弊端。讀：強化略讀、查讀等閱讀微技能，訓(xùn)練通過尋找關(guān)鍵詞，主題句等方式更快速并準(zhǔn)確的確定文章的段落大意，理清文章的總體框架與脈絡(luò)。繼續(xù)運用已經(jīng)掌握的基本猜詞技巧猜測部分單詞，并在上下文體驗中感受某些佳句給讀者帶來的深層含義。寫：學(xué)習(xí)在對事物進行理性思考的基礎(chǔ)上，運用恰當(dāng)?shù)木湫团c詞匯描述對事物正反面的不同觀點，同時更應(yīng)注重掌握一些必要的過渡詞增加此類寫作的條理性與層次感，并應(yīng)熟悉議論性作文的基本寫作框架。情感態(tài)度與文化意識（1）.進一步培養(yǎng)小組合作學(xué)習(xí)的能力，通過調(diào)查、采訪、討論等活動完成任務(wù)，取長補短，加強團體協(xié)作意識。（2）.引導(dǎo)學(xué)生用英語進行不同學(xué)科特點的思考，體會學(xué)科之間的聯(lián)系與區(qū)別。通過話題啟發(fā)學(xué)生積極思考，調(diào)動學(xué)生的學(xué)習(xí)興趣。（3）.指導(dǎo)學(xué)生用批判的思維去接受新的事物，增強他們的辯論意識與能力。（4）.意識到科技工作的艱苦以及所必需的個人品質(zhì)與素質(zhì)，鼓勵學(xué)生在學(xué)習(xí)過程中的創(chuàng)新精神與實踐能力。學(xué)習(xí)策略指導(dǎo)學(xué)生運用已學(xué)會的抓重點、做記號、摘筆記等方式對所學(xué)內(nèi)容進行整理與歸納，并鼓勵學(xué)生增加與教師和同學(xué)交流、合作，繼續(xù)培養(yǎng)正確的自我評價與相互評價的習(xí)慣，從而總結(jié)交流學(xué)習(xí)所得，進一步形成有效的學(xué)習(xí)方法。并指導(dǎo)學(xué)生把英語學(xué)習(xí)從課堂延伸到課外，發(fā)揮已掌握的使用工具書，查找資料、上網(wǎng)等方式增加用英語思維與表達的能力，了解實驗對于科學(xué)研究的重要性，樹立正確的向上的學(xué)習(xí)態(tài)度，形成具有批判性的看問題習(xí)慣。三、 教學(xué)內(nèi)容分析 本單元的中心話題是science and scientists。話題依附于聽力、對話、閱讀與寫作等語言載體中。本單元的話題內(nèi)容與學(xué)生的日常學(xué)習(xí)有著密切的關(guān)系，應(yīng)該說是以英語為媒體讓學(xué)生表達他們對平時理化生等理科課程，特別是相關(guān)實驗，所想到及感受到的內(nèi)容。因此，盡管本單元的話題對學(xué)生而言有著一定的難度，但卻有體現(xiàn)出了以學(xué)生為中心，貼近學(xué)生生活而又富有時代氣息的特點。Warming up設(shè)計了四幅與學(xué)生的理科課程有關(guān)的圖片，學(xué)生通過對日常熟悉的相干實驗工具及場地的識別，展開相關(guān)學(xué)科特點與學(xué)習(xí)的討論。同時在此基礎(chǔ)上，要求學(xué)生們在Listening部分能熟悉某些實驗室的規(guī)則及注意事項，掌握如何給予別人指導(dǎo)與說明，并能抓住文章的中心話題，捕捉相關(guān)細節(jié)內(nèi)容，回答有關(guān)的問題。Speaking則是一個極富時代氣息的討論練習(xí)。要求學(xué)生們能對現(xiàn)在熱門的尖端科技有所了解，（練習(xí)中提供了諸如Maglev train, cloning, nuclear energy, computer 與 space flight等內(nèi)容）然后能就這些新的科學(xué)技術(shù)與工具進行理性的辨證的思考，既能感受到它們給我們的生活帶來的巨大利益，同時也能發(fā)現(xiàn)其中所存在的不足與弊端，并能通過討論、對話等形式發(fā)表自己的觀點與想法。這一部分也應(yīng)該是本單元寫作內(nèi)容的一個鋪墊。Reading講述的是科學(xué)家Franklin著名的風(fēng)箏實驗，從而證明Lighting and electricity are the same的故事。學(xué)生在理解文章的基礎(chǔ)上，能充分感受到實驗對于科學(xué)工作的重要性及科學(xué)家是如何獲得事業(yè)上的成功的。同時能落實材料中所出現(xiàn)的一些單詞與短語的使用。Language Study是在本單元詞匯學(xué)習(xí)的基礎(chǔ)上，讓學(xué)生進一步了解并掌握一定的構(gòu)詞法。主要是兼類詞、一詞多義現(xiàn)象及合成詞的構(gòu)成。Integrating skills 通過學(xué)生對科學(xué)家是否應(yīng)利用動物進行實驗，從而達到發(fā)明新產(chǎn)品現(xiàn)象的討論，理性的從正反兩個方面看待這一問題。同時在閱讀、思考與討論的基礎(chǔ)上，寫下一篇闡明自己觀點、立場與看法的短文。四、 教學(xué)重點與難點1重點：（1）.掌握如何就某一話題給予別人指示與說明，能熟練運用 Dont do / Dont forget to / Make sure / Remember that / Do be careful of等結(jié)構(gòu)進行討論、對話與表演。（2）.能就某一話題進行合理的分析，并從不同的角度去分析問題，展示一個物體的利與弊兩個方面。同時能在討論時學(xué)會運用哪些結(jié)構(gòu)與單詞對事物進行評價，諸如“ Its good / bad / harmful for / Its dangerous / expensive / important / unnecessary/ It brings people / It can help people（3）.能繼續(xù)運用各種閱讀微技能進行有效的閱讀， 同時能在閱讀中繼續(xù)培養(yǎng)猜測單詞詞義的能力。同時掌握文中出現(xiàn)的單詞與短語的使用。（4）.能進一步了解一詞多義及合成詞的知識。以便能更好的區(qū)別單詞詞義與猜測單詞詞義，利用構(gòu)詞法知識擴充詞匯量，并能真正做到為閱讀服務(wù)。（5）.能把事物的正反利益和理性的思考落實到筆頭，即能清晰地就某一爭論性話題發(fā)表自己的立場，闡明原因。并能進一步運用基本的協(xié)作技能學(xué)會argumentative essay的寫作。2難點（1）.如何有效的讓學(xué)生就given topic進行合作，分析問題的利弊，并掌握相關(guān)的詞匯。（2）.如何能就課文內(nèi)容完成一些開放性的話題討論，能把課文的內(nèi)容得以延伸與拓展。（3）.如何更加有效的掌握并運用一些key words and expressions, such as make /do an experiment on, comfort, conduct, charge, a great of, prove, tear, sharp, explain, pick out, test on, doubt, conclusion and so on. （4）.如何能使議論性作文表達的更加完整與流暢。（5）.指導(dǎo)學(xué)生通過各種渠道如圖書館、網(wǎng)絡(luò)等資源查找資料。五、教學(xué)原則（1）以任務(wù)型教學(xué) (Task-based Language Teaching)作為課堂教學(xué)設(shè)計之理念，具體采用情景教學(xué)法（Situational Approach），交際教學(xué)法（Communicative Approach），整體語言教學(xué)法（Whole Language Teaching）等教學(xué)方法。從一定程度上說，人們使用語言是為了完成各種各樣的任務(wù)，而任務(wù)型的教學(xué)活動就是讓學(xué)習(xí)者通過運用所學(xué)語言來完成各種各樣的交際活動。學(xué)習(xí)者通過表達、溝通、交涉、解釋、詢問等各種語言形式來學(xué)習(xí)和掌握語言，實現(xiàn)目標(biāo)，感受成功。（2）在教學(xué)中突出交際性，注重讀寫的實用性；同時適時進行情感與策略調(diào)整，以形成積極的學(xué)習(xí)態(tài)度，促進語言實際運用能力的提高。（3）堅持“教師為主導(dǎo)，學(xué)生為主體，任務(wù)為基礎(chǔ)”的教學(xué)原則，在課堂教學(xué)的不同環(huán)節(jié)教師應(yīng)扮演自身作為“設(shè)計者，研究者，組織者，促進者，協(xié)調(diào)者”的角色。（4）貫徹“教中學(xué)，學(xué)中用”策略，真正使學(xué)生學(xué)以致用。六、 教材與任務(wù)安排 本單元計劃為六課時：Warming up & Listening （1課時）， Speaking (1課時) ，Reading (2課時)， Grammar (1課時)， Integrating skills（1課時）。同時本單元安排的三大任務(wù)是：（1）.參考學(xué)校理化生實驗室，擬訂英語語音實驗室規(guī)則。并以墻報的形式進行比較后，選出其中最佳的規(guī)則，然后上報給學(xué)校。（2）.科學(xué)家創(chuàng)造發(fā)明故事比賽。要求學(xué)生在課外收集國內(nèi)外發(fā)明家的故事，經(jīng)過整理后，能以故事、小品、對話等不同形式表演出來。在全班同學(xué) 的共同評判下選出最佳故事及選手。（3）.當(dāng)?shù)責(zé)狳c爭論問題討論。搜集本地目前人們所爭論的一些問題，并能采集到不同的人對于這一問題的不同看法與見解，并能進行思考后，發(fā)表自己的立場與觀點。然后寫一封書信給當(dāng)?shù)叵鄳?yīng)的管理機構(gòu)或政府部門。Unit 16 Scientists at workPeriod 2 ReadingI.

Teaching aims:1. Review the words learnt in the last period and learn their different meanings by heart.2. Learn to use the rules of the formation of compounds to guess the meaning.3. Learn to describe the two parts of some compounds.II.

Teaching procedures:Step1 RevisionLet some students retell the text.Step2 Lead-inAfter having learnt many words, we can find that some words have more than one parts or speech or a meaning. For example, bank can mean not only the ground near a river, but also the establishment for keeping money. It is one factor of words and we may find that if some words are combined, a new word comes into being. Today we will talk about these two phenomena.Step 3 Word study1. Finish the exercise in this part.2. Let the Ss think more examples of words that have more than one meaning. Then make a conclusion to help them to decide word meaning in a specific situation.Step 4 Grammar1.Finish the exercises in this part.2 Train the Ss reading and speaking ability by making a debate after reading the material3. Talk about the word formation, especially compounds. And the noun compounds and adjective compounds.4. Let the students talk about some compound words, then conclude the conditions.Step 5 Practice1) ache He has an ache in his chest. continous and dull pain I am aching all over. suffer from the pain v.2) lie Our school lies in Anqing He told a lie to his teacher.3) order Get your ideas into some kind of order before beginning to write. He gave his order to the waiter. We ordered him to leave immediately.4) like I like the one on the left. They are not twins, but they ate very like. I am going to be a pop star like Michael Jackson.HomeworkReview the compound words and preview next part.Do Exx. 1-2 on P91 in workbook.教學(xué)反思：在這個課時里一個很重要的步驟就是復(fù)習(xí)上個課時里的課文，讓學(xué)生復(fù)述實驗過程。在詞匯學(xué)習(xí)中能很好地復(fù)習(xí)課文中出現(xiàn)的單詞和詞組，讓學(xué)生了解一個單詞未必只有一個意思，很可能擁有完全不同的意思，這就需要大家根據(jù)上下文來進行判斷了。學(xué)生的聯(lián)想能力很強，我感覺只要給他們機會，給他們時間，他們會做得很好，超出我們的預(yù)料，在今后的教學(xué)中要注意培養(yǎng)他們這方面的能力。Period 4I.
