231、掌握听力和快速阅读的能力和技巧;2、提升灵活运用语言的能力;3、了解著名科学家的事迹，向科学家学习。本课首先通过泛听，了解听力材料的基本大意，然后让学生浏览3个问题，带着问题去听，一方面降低听力难度，另一方面掌握听力技巧。最后在听力难点上停顿，让学生真正理解材料，做到听的能力的提升。在speaking这一环节上，先让学生热身，做brainstorm。然后把学生分为两组，在同一事物上有两种不同的观点，如何能清晰表达出来，这很能培养学生的能力。在阅读方面是重点培养学生的泛读能力，通过快速阅读，找到正确答案。Whatdoyouthinkofthestory“SatisfactionGuaranteed”?(1)Doyoulikethestory?Why?(2)DoyouthinkhumanwillbeabletomakearobotlikeTony?(3)DoyoulikearobotlikeTonyatherhouse?Discussion:Listening(Page15)ListentoaconversationbetweenMollyandKate,whoarediscussingthestory“SatisfactionGuaranteed”,thentickthecorrectboxes.1.Whoreallylikesthestory?2.WhothinksthatClairelovedTony?3.WhothinksthatTonylovedClaire?MollyKate√√√Unit2UsinglanguageListening4.WhothinksthatthepurposeofTony’sactionswastomakeClairefeelgoodaboutherself.5.WhothinkstakingTonyawaymusthavehurtClaire?6.Whosaidthatmakingarobotsomuchlikeamanwasboundtocausetrouble?MollyKate√√√Speaking1.2.3.4.Theexpressionsaboutsuppositionandbelief:Ithink/Isuppose/Iguess/IwonderIbelieveMaybe…Imagineitissometimeinthefutureandpeoplehaverobotsintheirhousestodothehousework.Dividethestudentsintotwobiggroups,groupAandgroupB.GroupAwillhavethetasktodiscussthequestion:Whatdoyouthinkthepositiveeffectsofthissituation?GroupBwillhavetodiscussthequestion:Whatdoyouthinkthenegativeeffectsofthissituation?Andeachbiggroupcanbedividedintogroupsoffour.Duringdiscussion,pleaseusewordsintheaboveform.Intheend,eachbiggroupchoosetwostudentstopresenttheirideastothewholeclass,andtheothergroupmatescanaddhisorherpoints.Unit2RobotsAbiographyofIsaacAsimovReadinganddiscussingLeadingin艾萨克·阿西莫夫IsaacAsimov,(1920-1992)，美籍犹太人，为本世纪最顶尖的科幻小说家之一，曾获代表科幻界最高荣誉的雨果奖和星云终身成就「大师奖」。以他的名字为号召的「艾西莫夫科幻杂志」，是美国当今数一数二的科幻文学重镇。阿西莫夫是一位多产得惊人的作家，自50年代初，至今已出版了300多部著作。在家中图书室（1976年）Oldphoto阿西莫夫与珍尼特演讲军旅戎装阿西莫夫追悼会现场作品：I,Robot《作品100》《最新科学指南》1920192219231929borninRussia.sisterbornmovedwithfamilytoNewYorkParentsboughtacandystore.Motherhadherthirdchild.startedworkingincandystore.Startedtotakehimselfseriouslyasawriter.1931DateEvent19391942-1945BeanhavingstoriespublishedinsciencefictionmagazinesGainedMastersdegreeinchemistry.Finishedworkingincandystore.GotmarriedWorkedasjuniorchemist,PhiladelphiaNavyYardGotPhDinchemistry.19411948194219501951-1953Becameabiochemistryteacher,BostonUniversitySchoolofMedicine.Publishedhisfirstnovel.Developedthreelawsforrobots.Published“I,Robot”Published“TheFoundationTrilogy”andwonanawardforit.Publishedfirstsciencebook.Becameafull-timewriter.19491953195819731992Divorcedhisfirstwife.Hadabloodtransfusion.BecameinfectedwithHIV.Marriedforasecondwife1983DiedinNewYorkReadthroughthetextandthenfindouttheanswerstothefollowingquestions:1.WhatsubjectdidAsimovteach?2.Whendidhestarthavingstoriespublished?3.Howmanychildrendidhehave?Scanning:1.WhatsubjectdidAsimovteach?2.Whendidhestarthavingstoriespublished?3.Howmanychildrendidhehave?Hetaughtbiochemistry.In1939.Twochildren,asonandadaughter.1.WhowasIsaacAsimov?A.AnAmericanscientistandwriterwhogothisPhDinphysicsin1948.B.ARussianscientistandwriterwhomarriedtwice.C.ARussian—Americanwriterandscientistwhobecameafull—timewriterin1958.D.AnAmerican-Russianwriterandscientistwhohadtwochildren.Comprehending2.WhatwasAsimovbestknownfor?A.Hismysterystories.B.Hissciencefictionstories.C.Hisscienceandhistorybooks.D.HisbooksabouttheBibleandaboutShakespeare.3.AllthefollowingstatementsareTRUEexcept_______.A.Asimov’stalentforwritingbecameobviousatage12.B.Hebeganhavinghisstoriespublishedinsciencefictionmagazinesin1939.C.Hepublishedhisfirstnovelin1950.D.Hepublishedhisfirstsciencebookin1953.4.InwhichbookdidAsimovdevelopasetofthree“laws”?A.TheFoundationTrilogy.B.I,Robot.C.Inhisfirstnovel.D.Inhisfirstsciencebook.5.WhatmighthappeninaworldwheretherewererobotsifAsimov’sthreelawsdidn’texist?A.Mayberobotswillharmorinjurehumanbeings.B.Mayberobotswilldisobeyhumanbeings.C.Inordertoprotecttheirownexistence,robotsmayinjurehumanbeings.D.Alloftheabove.1.Whichsetoflawsdoyouthinkisbetter?Givereasons.2.Whichlawisthestory“SatisfactionGuaranteed”basedon?3.WhatmighthappeninaworldwheretherewererobotsifAsimov’sthreelawsdidnotexist.Discussion:ForagainstWriteashortsummaryofAsismov’slifein150-200words.Followthestepsbelow.1.LookbackatthetimelineofAsimov’slife.2.Underlinethemostimportantpartsofhislifethatmadehimagreatwriterofsciencefiction.Thiscanserveastheoutlineofyoursummary.3.BeginbygivingyourassessmentofAsimovasawriter.Thenwritedowntheimporantpartsyouhaveunderlined.4.Useaclearsimplestyleasifyouwerewritingtoyoungerstudentsinyourschool.HomeworkFinishthecompositionafterclassandexchangethecompositionswiththedeskmates,thencorrectthemistakesforeachother.
