第第頁人教版（2024）八年級上冊英語Unit4SectionB（1a-1f）教案課題Unit4AmazingPlantsandAnimalsSectionB(1a-1f)學(xué)段初中年級八課型閱讀課課時(shí)4學(xué)科English單元主題分析本單元的主題屬于“人與自然”范疇，涉及“自然生態(tài)”主題群中的“熱愛與敬畏自然，與自然和諧共生”子主題內(nèi)容。本單元以“神奇的動(dòng)植物”為主題，圍繞植物和動(dòng)物的獨(dú)特之處展開探究，深入理解自然生物的奇妙特性及其與人類生活的密切關(guān)聯(lián)。學(xué)生不僅能掌握形容詞最高級的用法，還能培養(yǎng)對自然界的敬畏之心，進(jìn)而思考人類與動(dòng)植物和諧共生的意義。文本解讀What:本課是人教版(2024)八年級上冊第四單元AmazingPlantsandAnimals的第四課時(shí)的閱讀課，本文以蜜蜂為例，探討了動(dòng)植物與人類的共生關(guān)系，屬于科普類說明文。文章從蜜蜂的生態(tài)價(jià)值、辛勤工作、現(xiàn)存問題與呼吁三個(gè)維度展開，采用“現(xiàn)象引入→核心功能→補(bǔ)充細(xì)節(jié)→問題反思”的遞進(jìn)邏輯，輔以數(shù)據(jù)（如“50-100朵花”）和擬人化表達(dá)（如“勤勞的動(dòng)物”），兼具科學(xué)性與可讀性。Why:本文的核心價(jià)值在于將生物學(xué)（授粉機(jī)制）、生態(tài)學(xué)（物種關(guān)聯(lián)）與語言學(xué)（形容詞用法）結(jié)合，實(shí)現(xiàn)跨學(xué)科學(xué)習(xí)；通過“假設(shè)-實(shí)證-行動(dòng)”鏈條，引導(dǎo)學(xué)生從認(rèn)知（蜜蜂功能）到共情（危機(jī)擔(dān)憂），最終落實(shí)責(zé)任（保護(hù)措施），培養(yǎng)批判性思維與問題解決能力；破除“人類中心主義”，通過“我們需要彼此”的論述，建立生命共同體意識。從課標(biāo)視角看，文本完美契合“人與自然”主題，同時(shí)提供豐富的語言輸入，為后續(xù)寫作奠定基礎(chǔ)。How:本文教學(xué)可采取“三階遞進(jìn)”策略：感知→探究→行動(dòng)。首先，通過討論神奇的動(dòng)植物引出蜜蜂，播放其相關(guān)視頻引導(dǎo)學(xué)生關(guān)注蜜蜂的生態(tài)價(jià)值，完成思維導(dǎo)圖梳理核心信息；其次，聚焦語言特色，通過“形容詞分類墻”活動(dòng)（如情感類/評價(jià)類）和小組討論，深化對最高級表達(dá)和生態(tài)鏈的理解；最后，遷移至真實(shí)問題解決，如分組設(shè)計(jì)“校園護(hù)蜂方案”將文本中的科學(xué)知識、語言表（hard-working,themostimportant）和情感呼吁轉(zhuǎn)化為創(chuàng)造性輸出，實(shí)現(xiàn)從“讀懂”到“用活”的跨越，同時(shí)滲透生命教育。學(xué)情分析1.學(xué)生基本情況授課對象為初中生（八年級），已具備基礎(chǔ)的英語閱讀能力，能理解簡單說明文的主旨和細(xì)節(jié)，但對長難句和隱含邏輯關(guān)系的分析仍需指導(dǎo)。2.已有知識經(jīng)驗(yàn)學(xué)生對蜜蜂、授粉等生態(tài)概念有一定了解（如小學(xué)科學(xué)課涉及），但對具體數(shù)據(jù)和生態(tài)鏈的深層聯(lián)系（如人類食物系統(tǒng)依賴?yán)ハx）認(rèn)知較模糊。學(xué)生已學(xué)過形容詞原級和比較級，但對最高級（themostimportant,themostamazing）的準(zhǔn)確使用，尤其是多音節(jié)詞變形（如interesting→themostinteresting）可能不熟練。3.學(xué)習(xí)難點(diǎn)預(yù)測若文本中的科學(xué)術(shù)語（如pollination,ecosystem）解釋不足，部分學(xué)生可能因理解困難而失去興趣。4.教學(xué)對策通過頭腦風(fēng)暴激活已有知識，預(yù)教關(guān)鍵術(shù)語；結(jié)合本土案例增強(qiáng)現(xiàn)實(shí)關(guān)聯(lián)性，避免文本停留于理論。教學(xué)目標(biāo)語言能力1.Studentswillbeabletoidentifyandunderstanddescriptiveadjectivesandsuperlativeformsinthetext.2.Studentswillextractkeydetails(eg,pollination,honeycomb,beecommunication)tosummarizetheecologicalroleofbees.文化意識1.Studentswillrecognizetheglobalsignificanceofbeesinagricultureandecosystems,fosteringrespectfornature.2.Cultivatestudents'awarenessofbiologicalconservationandstimulatetheirinterestinprotectingbees.思維品質(zhì)1.Analyzecause-effectrelationships(eg,"Whatifbeesdisappeared?")andproposesolutionstoprotectbees.2.Usethemindmaptoorganizeinformationhierarchically.學(xué)習(xí)能力1.Masterkeyinformationaboutbeesdescribedinthearticlethroughreadingskillssuchasskimmingandscanning,andimprovereadingability.2.Throughautonomousexplorationandgroupdiscussion,completethewritingoutputaboutbees.教學(xué)重難點(diǎn)教學(xué)重點(diǎn)Guidestudentstofindandunderstandtheadjectivesandsuperlativeformsusedtodescribebees.教學(xué)難點(diǎn)Helpstudentsunderstandtheimportanceofbeesandtheirconnectiontootherlivingthings.教學(xué)過程設(shè)計(jì)教學(xué)環(huán)節(jié)教師活動(dòng)學(xué)生活動(dòng)設(shè)計(jì)意圖Step1Lead-inT:Wehavelearnedsomeamazingplantsandanimals,suchasbamboo,ginkgotrees,bluewhales,elephants.Theyallplayimportantrolesinourworld.Whatotherplantsandanimalsdoyouknow?Studentshaveafreetalkandanswerthequestion.通過問題導(dǎo)入，幫助學(xué)生了解自然界中的神奇動(dòng)物，喚起學(xué)生熱愛自然、探索自然的好奇心和求知欲。Step2Pre-readingWorkon1a1.Teacherleadsstudentstolookatthetitleandpictureof1b,topredictthegeneralcontentofthearticle,andasks:Whatisthetextabout?Ss:Bees!2.Teacherplaysashortvideoofbeescollectingnectarandpollinatingflowers.3.Afterwatchingthevideo,teacherorganizesstudentstohavea“BeeKnowledgeQuickQuiz”.Teacherpreparessimplequestionsaboutbees,suchas:①Howdobeeshelpplants?②Whatdoesabee'shomelooklike?③Howdobeescommunicate?Afterstudentsanswer,theteachersummarizestheirresponses,andguidesthemtothinkabouttheimportanceofbeesinnature,leadingintothetextin1b.1.Studentshaveapredictionaboutthetextof1b.2.Studentswatchavideoaboutbees.3.Studentshavea“BeeKnowledgeQuickQuiz”.根據(jù)標(biāo)題和圖片預(yù)測文本內(nèi)容，激發(fā)學(xué)生的興趣，降低閱讀焦慮。通過播放蜜蜂相關(guān)的視頻，為學(xué)生提供背景知識，有助于學(xué)生更好地理解文本。通過快問快答的形式，激活學(xué)生對蜜蜂的已有知識，激發(fā)其學(xué)習(xí)興趣，通過總結(jié)和引導(dǎo).幫助學(xué)生建立蜜蜂與自然界重要性的聯(lián)系.為深入學(xué)習(xí)課文內(nèi)容做好鋪墊。Step3While-readingWorkon1bSkimming1.Lookthroughthepassageandunderlinetheadjectivesthewriterusestodescribebees.2.Askstudentstoreadthetextquicklyandfindthemainideaofeachparagraph.Paral:Theconnectionbetweenpeople,plantsandanimals,andtheimportanceofbees.Para2:Beesarehard-workingandplayaroleinpollination.Para3:Beesareinterestingandhowtheycommunicate.Para4:Theimportanceofbeesintheecosystemandtheneedforprotection.Scanning1.Askstudentstoreadthetextcarefullyandfindtheanswerstosomespecificquestions.①Howmanyflowersdobeesoftenvisitononetrip?②Howdobeescommunicatewitheachotherwhentheyfindnewfood?③What'stheproblemwithbees?2.Inviteseveralstudentstofindtheanswersinthetextbook.Workon1c1.Teacherasksstudentstoreadthetextagainandcompletethemindmapwiththeinformationfromthetext.Iftherearedifficulties,theycandi
