仁爱版初中英语九年级上册教案设计 Unit 4 Topic 2 Section C

Unit4AmazingScienceTopic2I’mexcitedaboutthethingsthatwillbediscoveredinthefuture.SectionCⅠ.Materialanalysis本课是九年级第四单元第二话题的第三课时。主活动是1a。1a是承接SectionA和SectionB设计的。因为在这两个Section里总是提到Mars，学生已经对它产生了兴趣。“宇宙”属于“自然”的一部分。而“自然”正是课程标准要求的话题。1b属于理解型任务，学生如果能独立完成表格，也就说明他们已经掌握了1a的内容。1c看似让学生讨论，其实通过学习1a,学生都能对所给的问题作出正确的判断。2这个任务是为3a和3b作铺垫。学生通过学习本课，可以对火星有大致的了解，也有助于激发学生探索宇宙的好奇心。3a和3b这两个任务关联性很强，3b只有在学生完成了3a之后才能完成，没有3a的信息，3b就不能进行。把这两个任务留作家庭作业较好。Ⅱ.Teachingaims1.Knowledgeaims：掌握本课的重点词汇和短语，了解火星的相关知识。2.Skillaims:能够通过所获取的文字信息，对火星有所了解，拓展自己的知识面。3.Emotionalaims:(optional)激发学生探索宇宙的兴趣。 4.Cultureawareness:(optional)Ⅲ.Thekeypointsanddifficultpoints1.Keypoints:Wordsandphrases:storm,weigh,journey,excitement,generally,limit,benamedaftersb.,as…as…,atadistanceof…,Ittakes…todosth.Sentences:Itsdiameteris53%aswideasthatoftheearth.YoucantellwhichplanetisMarsbecauseitisbright,redinthenightsky.ThegravityonthesurfaceofMarsisabouttwo-fifthsasstrongasitisonearth.IttakesaspaceshipabouteightmonthstoreachMarsfromtheearth….eachother.IthasbeentwodayssincewelandedonMars.Grammar:passivevoiceDifficultpoints：Itsdiameteris53%aswideasthatoftheearth.IthasbeentwodayssincewelandedonMars.Ⅳ.Learningstrategies通过1a学习预测文章的内容。通过1b利用图表复述课文。Ⅴ.Teachingaids火星、罗马战神Mars、太阳系等的图片/乒乓球/小皮尺/小黑板/ppt等。 Ⅵ.TeachingproceduresStage(timeperiod)InteractionpatternsTeacheractivityStudentactivityRemarks1Gettingstudentsreadyforlearning(5mins)ClassactivityPresentsomepicturesandobjectstolearnthenewwordsandphrases:solarsystem,Roman,god,benamedaftersb.,diameter,gravity.T:What’sthis?T:Oh,yourgeographyisquitegood.It’ssolarsystem.T:What’sthis,then?T:Whoishe?T:HeistheRomangodofwar,Mars.AndtheplanetMarsisnamedafterhim.T:Lookatme!Iwillmeasurethediameteroftheping-pongball.Oh！Itsdiameteris5centimeterslong.CouldyoutellmewhatLearnthenewwordsandphrases.Ss:太阳系。Ss:火星。Ss:Sorry.Ss:直径。Ss:重力。允许学生用汉语表述新词。老师要及时用英语板书并讲解：solarsystem,Roman,god,benamedaftersb.,diameter,gravity。 diametermeans?T:Yougotit!(dropstheball)Oh,mygod!T:Doyouknowwhytheballfallstotheground?T:Yes!It’sthegravitythatmakesitfalltotheground.YouknowthestoryofNewton,don’tyou?Ss:直径。Ss:Yes.Ss:重力。2Pre-reading(2mins)IndividualworkLettheSsreadthestatementsin1aandencouragethemtopredictwhichis/areright.T:Now,readthefourstatementsin1aandpredictwhichofthemisorareright.WritedownF/Tontheleft.Readthestatementsin1aandpredict.把这四点用小黑板或大屏幕呈现更好。这样学生就不用打开课本，以保持神秘感。学生预测后不要马上判断正误。3While-reading(10mins)IndividualworkStep1:LettheSsread1aquicklyandchecktheanswers.T:Now,pleaseread1aquicklytocheckwhetheryouhavepredictedcorrectly.WhenRead1aquicklyandchecktheanswers.
