高中英語-Book 3 Unit 4 Astronomy the science of the stars教學(xué)設(shè)計學(xué)情分析教材分析課后反思

Book3Unit4Astronomy:ThescienceofthestarsLanguagepoints課標(biāo)分析新課標(biāo)要求，要樹立新的教學(xué)觀念應(yīng)改變以教師為中心、單純傳授書本知識的教學(xué)模式。教師應(yīng)幫助學(xué)生發(fā)展探究知識的能力、獲取信息的能力和自主學(xué)習(xí)能力。要鼓勵學(xué)生積極嘗試觀察、思考、歸納、總結(jié)等學(xué)習(xí)方式，改變死記硬背、機械模仿的學(xué)習(xí)方式。本節(jié)課遵循課標(biāo)要求，改變傳統(tǒng)的授課模式，通過找出重點句子，并引導(dǎo)幫助學(xué)生注意到特定的知識點和語言現(xiàn)象。這種做法旨在幫助學(xué)生發(fā)展探究知識的能力、獲取信息的能力和自主學(xué)習(xí)能力。在33餓3某些比較長和難度較大的句子，通過提問題和設(shè)置填空題鼓勵學(xué)生嘗試通過觀察、思考、歸納等學(xué)習(xí)方式，并進一步設(shè)置鞏固訓(xùn)練加強知識點的落實。Book3Unit4Astronomy:ThescienceofthestarsLanguagepoints教材分析本單元的中心話題是“天文學(xué)”，因為涉及太陽系、地球上的生命起源、宇宙大爆炸、月球探秘、黑洞效應(yīng)等，主要內(nèi)容是圍繞地球上生命的起源展開，所以對學(xué)生來說，詞匯和語言稍顯難掌握。教材通過對宇宙大爆炸理論進行科學(xué)性分析，推斷出地球上生命的由來以及生物進化的過程。正文共五段，除了第一段“導(dǎo)入”和最后一段“結(jié)語”以外，其余三段都是集中在“生命起源”這一主題上。文章最后講述的現(xiàn)象發(fā)人深省“…theearthmaybecometoohottoliveon.”它關(guān)系到地球上生命的未來。所以，語言點的講解也是按照這個順序來挑選需要重點講解的句型和語言現(xiàn)象。另外通過一個虛構(gòu)的科幻故事介紹了地球引力和月球引力的不同，同時對“黑洞”效應(yīng)的描寫也是通過這一樣的方式展開的。這部分在之前已經(jīng)閱讀完課文的基礎(chǔ)上，重點講解了兩個語言點。Book3Unit4Astronomy:ThescienceofthestarsLanguagepoints學(xué)情分析本班學(xué)生語言知識基礎(chǔ)較好，詞匯比較豐富，所以在概括總結(jié)語言知識方面自主性比較高。學(xué)生能夠按照老師要求，積極主動參與到課堂教學(xué)中來，并且能夠理解老師的引導(dǎo)，探索語言現(xiàn)象背后的語言規(guī)律。部分學(xué)生基礎(chǔ)薄弱，在跟隨教師授課步驟上比較被動。需要老師更多指導(dǎo)和引導(dǎo)，并加以課外輔導(dǎo)才能取得顯著進步。根據(jù)本節(jié)課學(xué)生接受知識情況，可以考慮在課后酌情添加鞏固練習(xí)，并根據(jù)不同層次的學(xué)生調(diào)整練習(xí)難度。Book3Unit4Astronomy:ThescienceofthestarsLanguagepoints教學(xué)設(shè)計StepIReviewthewordsandphrasesinthetext1.__________n.天文學(xué)→____________n.天文學(xué)家→____________宇航員n.2._________n.宗教；宗教信仰→________宗教的adj.3.globen.地球儀;地球→________adj.全球性的;全世界的4.v_________adj.猛烈的；激烈的；強暴的→adv.____________→____________暴力n.5.________prep.不同；不像→________像prep.→____________可能的adj.→__________不可能的adj.6.____________adj.有害的→________害處，有害v./n.→對…有害(短語)________________________7.__________vi.存在；生存→____________存在n.→開始存在/形成(短語)_______________________8.____________n.生物學(xué)→____________n.生物學(xué)家9.gentleadj.溫和的；文雅的→adv.____________10.physicsn.→____________n.物理學(xué)家StepIIImportantsentencesinthetext;readandtrytorecite1.Whatitwastobecomewasuncertainuntilbetween4.5and3.8billionyearsagowhenthedustsettledintoasolidgolbe.2.Theywereintimetoproducecarbondioxide,…andothergases,whichweretomaketheearth’satmosphere.3.Itwasnotimmediatelyobviousthatwaterwastobefundamentaltothedevelopmentoflife.4.Thisproducedachainreaction,whichmadeitpossibleforlifetodevelop.5.Sowhetherlifewillcontinueontheearthformillionsofyearstocomewilldependonwhetherthisproblemcanbesolved.6.Wearetoofarfromtheearthnowtofeelitspull.7.Whenwegetclosetothemoon,weshallfeelitsgravepullingus,butitwillnotbeasstrongapullastheearth’s.ButwhenItriedtostepforward,IfoundIwascarriedtwiceasfarasontheearthandfellover.Leavingthemoon’sgravitywasnotaspainfulasleavingtheearth’s.StepIIIAnalyzethesentences1.Whatitwastobecomewasuncertainuntilbetween4.5and3.8billionyearsagowhenthedustsettledintoasolidgolbe.Note:whatitwastobecome在句中做__________what在從句中做____語。(1)______________________(使每個人吃驚的是）wasthathedidn’tcometothemeeting.what在從句中做____語。(2)____________（他所做的）addedtoourdifficulty.what在從句中做____語。(3)Chinaisnotlonger_________________(以前的樣子).what在從句中做____語。Completethefollowingsentences:(1)我們得不到的似乎總是比我們擁有的要好的多。(2)________________________(讓這所學(xué)校驕傲的)was_____morethan90%ofthestudentshadbeenadmittedtokeyuniversities.2.Theywereintimetoproducecarbondioxide,…andothergases,whichweretomaketheearth’satmosphere.Note1:intime1)及時（+forsth/todosth）2)最終；遲早(=soonerorlater)ontime
