Unit4UsingLanguage1.让学生能读懂文章的大意及细节，并能捕捉到题中的相关的细节在文中的位置。2.帮学生梳理文中的重点语言点的用法，并引导他们去运用，并进行相关的拓展。本节课是unit4Astronomy:thescienceofthestars的第二篇小课文，设计的意图主要是让引导学生对本文中的细节问题进行准确处理，除此之外，对文中的重点考点及其延伸做必要恰当的处理，做到拓展有度，拓展有据，也就是根据考纲进行补充，使这节课的英语教学不局限于课本，但又不超越大纲。首先，用和themoon相关的图片导入，引发并激起学生的兴趣，从而自然的过度到让学生描述thethreewaysinwhichgravitychangedforLiYanping。其次，让学生listentothetext,然后填好表格，从而达到了听读结合的目的。总之，任务型阅读法教学帮学生更深层次的理解了课文。本文的语言点教学部分，有解释，有拓展，讲练结合，实现了重点语言点的突破。spacewalk★Lookatthepictures!★WritedownthethreewaysinwhichgravitychangedforLiYanping.ReadingI----scanning&skimming(2m)ThewaygravitychangedLefttheearthInspaceOnthemoon3.Itbecameverylight.1.Thegravitybecameverystrong.2.Thegravitydisappeared.Hisweightschangedthreetimestoo.Nowlistentothepassageandwritethemdown.usinglanguagereadingTheweightchangedLefttheearthInspaceOnthemoonHebecameveryheavy.Hehadnoweightandcouldfloataroundlikeafeather.Hewasaboutone-sixthofhisweightontheearth.Languagepointsinthispassage1.LastmonthIwasluckyenoughtohaveachancetomakeatripintospacewithmyfriendLiYanping,anastronomer.上个月我有幸得到一个机会同我的朋友，一位宇航员李彦平一道去太空旅行。enough的用法:1）形容词作定语：enough用在名词前、后都可以。Ihaveenoughtimetodothework./Ihavetimeenoughtodothework.我有足够的时间做此项工作。2）用作副词修饰形容词或副词表示程度:enough一般放在形容词或副词的后边。longenough,fastenough,quicklyenough等。但一般不说：enoughlong,enoughfast,enoughquickly.Theboyisoldenoughtogotoschool.这孩子到上学的年龄了。3）用作副词修饰动词时也需放在动词之后。Themeatisnotcookedenough.肉炖得不够熟。IfIhad_____________________(足够长的假期),I’dvisitEurope,stoppingatallthesmallinterestingplaces.alongenoughholiday2.…theforce…forcen.力量，暴力，军队vt.强制，逼迫，用力打某物comeintoforce开始生效；开始实施put…intoforce施行（法律等）forcesbtodosth迫使某人做某事forcesthonsb勉强接受某物forcefuladj.有力的forcedadj.强迫的3.Thenwewereoff.随后我们就启程了。beoff=setoff出发；动身与off相关的短语:see...off送行jumpoff跳下giveoff散发showoff炫耀getoff下车takeoff脱下turnoff关闭payoff付清；还清4.Whenwegetclosertothemoon,weshallfeelitsgravitypullingusbutitwillnotbeasstrongapullastheearth’s.getcloseto靠近，接近，指动态变化becloseto距......近，指状态Theschoolisclosetothepostoffice.1).“A+be+倍数+as+形容词原级+as+B”.Thistreeisthreetimesastallasthatone.Hisfatheristwiceasoldashe.5.ButwhenItriedtostepforwardIfoundIwascarriedtwiceasfarasontheearthandfellover.2).“A+be+倍数+形容词比较级+than+B”TheYangtzeRiverisalmosttwicelongerthanthePearlRiver.长江差不多比珠江长两倍。Thenumberofstudentsinourschoolisthreetimeslargerthanthatintheirs.我们学校的学生数量比他们学校的多三倍。3).“A+be+倍数+the+名词(size,length,amount)+of+B”Thenewlybroadenedsquareisfourtimesthesizeofthepreviousone.新扩建的广场是未扩建时的四倍大。经过实验，这种细胞已经变得有那种细胞的三倍大了．1.Aftertheexperiment,thiscellhasbecomethreetimesaslargeasthatone.2.Aftertheexperiment,thiscellhasbecometwicelargerthanthatone.3.Aftertheexperiment,thiscellhasbecomethreetimesthesizeofthatone.6.getthehangofsth.查看某物运作了解…..的意义我一直想知道这部新的打字机的用法.I’vebeentryingto______________thisnewtypewriter.我不十分了解你的论据的意义.Idon’tquite__________________yourargument.getthehangofgetthehangof7.Wewatched,amazedasfirebrokeoutontheoutsideofthespaceshipastheearth’sgravityincreased.amazed是过去分词，此处做状语用他进来的时候没有人注意到.Hecamein_________.unnoticed
