九年级英语下Unit 1 Life on Mars-welcome to the unit课件牛津版

Unit1LifeonMarsPlanet行星行星通常指自身不发光，环绕着恒星的天体。其公转方向常与所绕恒星的自转方向相同。一般来说行星需具有一定质量，行星的质量要足够的大且近似于圆球状，自身不能像恒星那样发生核聚变反应。恒星恒星是由炽热气体组成的，是能自己发光的球状或类球状天体。由于恒星离我们太远，不借助于特殊工具和方法，很难发现它们在天上的位置变化，因此古代人把它们认为是固定不动的星体。我们所处的太阳系的主星太阳就是一颗恒星。Doyouknowtheplaceinthepicture?Lookattheotherplanetsinsolarsystem.Doyouknowtheplace?Listentothedialogueandanswerthefollowingquestions1.DidHobothinkEddielikedMars?2.HowdoesEddielikelifeonMars?3.WhydoesEddiehatelifeonMars?Howdoyoulike..=Whatdoyouthinkof..?E.g.HowdoyouliketheTVplay?=WhatdoyouthinkoftheTVplay?Fourstudentsinagrouptofinish(Alifeinspace)anddiscussiflifeonMarsbetterthanonEarthatpresent.Tellusthereasons..IthinklifeonMarsisbetterthanthatonEarth.Therearefourreasons:firstly,wewillbecaredforbyrobots;secondly,therewillbenopollution;thirdly,Robotswillhelpuswithourhomework;fourthly,moneywillnotbeimportant.IthinklifeonEarthisbetterthanthatonMars……….tentcamerasunglassesmatchesguitarfootballfishingnetWalkmanUnit1tentUnit1cameraUnit1sunglassesUnit1matchesUnit1guitarUnit1footballUnit1FishingnetUnit1WalkmanWordgame1.Whenyoutraveltospace,youshouldwearitonyourhead.Whatisit？2.Youoftenwearthemonahotsunnydaytoprotectyoureyes.3.Akindofmachinelikeaperson.4.It’sasimplehousethatpeoplecanliveinwhentheygocamping.Homework1.Remembertheimportantvocabularyandexpressions.2.DotheexercisesonStudents’Book.
