高中英語人教版Unit2Cloning 【教學(xué)設(shè)計】克隆它將把我們引向何方

教學(xué)設(shè)計目標(biāo)定位：本節(jié)課為高二下學(xué)期的閱讀課，高中英語新課程標(biāo)準(zhǔn)要求通過閱讀課來培養(yǎng)學(xué)生的閱讀理解能力，兼顧聽、說、寫的能力。教師幫助學(xué)生學(xué)會高效閱讀是閱讀課教學(xué)的主要任務(wù)，針對這一要求，本節(jié)課側(cè)重訓(xùn)練學(xué)生利用不同的閱讀方法，提高獲取信息、整合信息、分析問題、解決問題的能力，并且能在對文章充分理解的基礎(chǔ)上，進(jìn)行語言運(yùn)用。語言知識目標(biāo)初步理解、掌握課文中關(guān)于克隆的詞匯，學(xué)習(xí)分析課文中的長難句子。閱讀技能目標(biāo)能獲取和處理文章中的主要信息。能夠掌握文中出現(xiàn)的重要的語言知識學(xué)習(xí)策略目標(biāo)掌握速讀、略讀、猜測詞義等閱讀策略。情感態(tài)度目標(biāo)讓學(xué)生認(rèn)識到克隆的利和弊。文化意識目標(biāo)了解克隆，正確地利用克隆技術(shù)來為人類服務(wù)。方法選擇：本節(jié)課以交互閱讀模式為主要閱讀方式，指導(dǎo)學(xué)生以閱讀材料為本，重視語言文字的解碼過程。同時注意調(diào)動他們的主觀能動性，幫助他們學(xué)會運(yùn)用有效的閱讀策略。教學(xué)過程中借助任務(wù)型教學(xué)途徑，設(shè)計語言實(shí)踐活動，發(fā)展學(xué)生的綜合語言運(yùn)用能力。教學(xué)流程：Step1DailyreportOnestudentcomestothefrontandgivesareportaboutadvantagesanddisadvantagesofscienceandtechnology.Step2leading-inTheteachershowssomepicturesandstartsadiscussionaboutcloning.Step3SkimmingTask1:What’sthemainideaofthepassage?Task2:MatchthemainideawitheachparagraphPara1:A.People’sattitudetowardscloning.Para2:B.TheproblemsofDolly.Para3:C.TheimpactofDolly.Para4:D.Twomajorusesandtheprocedureofcloning.Para5:E.Thedefinition（定義）ofcloning.Step4ScanningTask1.LookthroughPara2andanswerthefollowingquestions.(1)Whatarethetwomajorusesofcloning?(2)Whichoneiseasier,tomakeplantclonesoranimalclones?Task2.LookthroughPara3andfillinthechart.DollyProblemstateofhealthLifespan(壽命)Task3.Dothefollowingtranslationandwordguessing.(1).Translation:Ontheotherhand,Dolly’sappearanceraisedastormofobjectionsandhadagreatimpactonthemediaandpublicimagination.(2).Theword“controversial”inparagraph4probablymeans_________.A.complicatedB.arguableC.importantD.valuableTask4.DothefollowingTorFquestionsbasedonParagraph5.1.Peoplefearedsomeevilleadersmightusecloningtoreachtheirgoal.2.Alltheresearchintocloningwillbeforbidden.3.Religiousleadersareinfavorofhumancloning.Step5Enjoybeautifulsentences1.Cloningplantsisstraightforwardwhilecloninganimalsisverycomplicated.2.Atlastthedeterminationandpatienceofthescientistspaidoff.3.Thefactthatsheseemedtodevelopnormallywasveryencouraging.Step6QuestionandanswerThispartisforstudentstofindiftheystillhavequestions.Ifthereisany,theycanasktheirclassmatestohelpthem.Step7QuizNote:Thispartisverychallenging.Inthepicturetherearefivenumbers.Studentscanchoosetheirluckynumberandanswerquestions.Mostofthequestionsarebasedonwhattheyhavelearnedinclass.Step8.TestyourselfFillintheblankwithproperwords.Cloningisawayof_______(make)anexactcopyofanotheranimalorplant.Ithastwomajoruses.Oneis_______gardenersuseittoproduceplants.The______isthatitisvaluableformedicalresearchonanimals.________,theprocessofcloningisdifficult___________(undertake).Thefirstsuccessfulclone,Dollythesheep,madethewhole_________(science)worldfollowitsprogress,thoughithad________problemsthanthenormalsheep.Ontheotherhand,Dolly’sappearance_______(raise)astormofobjectionsandhadagreatimpact______themediaandpublicimagination.Differentpeoplehavedifferentopinionsonit.However,scientistsstillwonder_____
