初二现在完成时教案一、知识梳理:(一)、现在完成时1.构成现在完成时是由助动词have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。(1)肯定句式:现在完成时的肯定句式是―have(has)+过去分词Wehavejustfinishedourhomework.(2)否定句式:现在完成时的否定句式是―haven't(hasn't)+过去分词Wehave’n‗tstudiedUnit2yet(3)疑问句式:现在完成时的一般疑问句式是把助动词have或has提到主语之前。Haveyoureadthisstorybookyet?2.用法(1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet等副词修饰。如:-Haveyouhadlunchyet?-Yes,Ihave.I'vejusthadit.你(已经)吃午饭了吗?我刚刚吃过。(现在我不饿了)(2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。如:Hehastaughtheresince1981他自1981年就在这儿教书。(可能还要继续教)Ihave'tseenherforfouryears.我有四年没见到她了。(3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice,ever,never,threetimes等时间状语。如:IhavebeentoBeijingtwice.我去过北京二次1.Tom______theCDplayerfortwoweeks.A.haslentB.hasborrowedC.hasboughtD.hashad解析:A、B、C均为非延续性动词,在肯定句中不与表段时间的短语连用,故选D2.We______XiaoLisinceshewasalittlegirl.A.knowB.hadknownC.haveknownD.knew解析:现在完成时时常与for+时间段或since+过去时间点连用(含从句,从句过去时)。故应选C。3.-______you___yourhomeworkyet?-Yes.I_____itamomentago.A.Did;do;finishedB.Have;done;finishedC.Have;done;havefinishedD.will;do;finish解析:现在完成时与一般过去时容易混淆,就是因为它们所表示的动作都发生在过去,但二者又有区别:一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作,说话的侧重点在于陈述一件过去的事情,与现在没有关系;现在完成时表示与现在有关系的发生在过去的动作,它不与表示过去的时间状语(如yesterday,lastweek,amomentago等)连用。故应选B。4.Hurryup!Theplay__________fortenminutes.A.hasbegunB.hadbegunC.hasbeenonD.began解析:现在完成时中,非延续性动词不能与for和since引导的表示一段时间的状语连用,通常是用相应的延续性动词来代替。故应为C5.She’s_____________(live)hereeversinceshewasten.(用时态填空)解析:本题考查的是时态的运用,故应填lived/hasbeenliving6.Hisfather______thePartysince1978.A.joinedB.hasjoinedC.wasinD.hasbeenin解析:现在完成时中,非延续性动词不能与for和since引导的表示一段时间的状语连用,通常是用相应的延续性动词来代替。故应选为D。7.—______myglasses?—Yes,Isawthemonyourbedaminuteago.A.DoyouseeB.HadyouseeC.WouldyouseeD.Haveyouseen解析:现在完成时表示过去发生的动作对现在的影响.故应选D(二)、外研版八年级下册固定搭配和重点短语21.invitesbtodosth.邀请某人做某事2.thinkabout考虑3.makeup编造4.stopdoingsth.停止做某事5.comewith和.......一起去6.thefirstprize一等奖7.atthemoment此时,现在8.sofar到目前为止9.asksb.todosth.要求某人做某事10.enjoydoingsth.喜欢做某事11.afifteen-year-oldboy一个十五岁的男孩12.oneofthe+形容词最高级+名词复数最.......之一13.bedifferentfrom与.......不同14.countdown倒数15.sendsb.todosth.把某人送去做某事16.enteracompetition参加竞赛17.writeabout编写;写作18.thinkabout考虑19.travelaroundtheworld环游世界20.workfor效力于21.forexample例如22.lookforwardtodoingsth./sth.期盼;期待23.haveawonderfultime玩的开心24.apairof一双25.therestof剩余的二、课堂练习:1.完形填空(本大题有10小题,每一题1分,共10分)通读下面短文,掌握其大意,然后在每小题所给的四个选项中,选出一个最佳答案。Atramp(流浪汉)wassleepingonaparkbenchlateatnight.Amanandawomanwerewalkingl.Oneofthemtappedhim2andasked,“3.What'sthetime?”Thetrampwasveryangry4.“Idon'tknow!”hesaidangrily.“Ihaven'tgotawatch.”Andhewentbacktosleep.5lateranothermanwaspassing.Hewokethetrampupandsaid,“Iamsorrytobotheryou,butI6ifyoucouldtellme7.”Againthetrampsaidhe8.Bynowhewasveryfedup(厌烦之极),sohegotapenandapieceofpaperandwroteIDON'TKNOWWHATTHETIMEISonitandwentbacktosleep.Halfanhour9,apolicemanwaspassing.He10thesign,wokethetrampupandsaid,“It's2:30,sir!”l.A.pastB.passedC.topassD.passing2.A.onhisshoulderB.ontheshoulderC.tohisshoulderD.totheshoulder3.A.SorryB.HelloC.ExcusemeD.Pardon4.A.bybeingwokenupB.tobewokenupC.atbeingwokenupD.beingwokenup5.A.SometimesB.SometimeC.SometimesD.Sometime6.A.knowB.askC.wonderD.wait7.A.whattimeisitB.whatisthetimeC.whattimeitisD.whatwasthetime8.A.knewnothingB.didn'tknowC.knewnobodyD.didn'tanswer9.A.afterB.lateC.pastD.later10.A.readB.wasreadingC.readsD.reading2.短文填空(本大题有10小题,每一题1.5分,共15分)IamJackieLee,anAmericanChinese.Letmetellyouaboutmygrandfather'slifestory.Mygrandfatherwas(71)________in1932andgrewupinapoorvillageinFujian,China.Attheageof14,hefirstheardofAmerica.Itwassaidtobethelandofgoldandpoorpeoplecouldeasilybecome(72)________there.So,mygrandfathercametoAmerica.“Ihadthoughtitwaseasyto(73)________moneyinAmerica,”hetoldme,“ButwhenI(74)________inLosAngeles,Irealizeditwasnottrue.Icouldn'tfindagoodjobbecauseIspokelittleEnglish.IwantedtogotoalanguageschooltolearnEnglish,(75)________Icouldn'taffordit.Later,Iworkedinasmall(76)________,servingtheguests,cleaningupthetables,washingthedishesandsweepingthefloors.Iwassuch(77)________helpfulandhonestworkerthatmybosswaspleasedwithme.Iwaspopularwithmyworkmates,(78)________.LifebecameeasierandintheendIenteredaneveningschooltolearnEnglish.”Mygrandfatherkeptworkinghard,andfinallymade(79)________dreamcometrue.Thingsdonotcomeeasilyinlife.ThatiswhatIhavelearned(80)________mygrandfather.参考答案答案:1.A2.B3.C4.C5.D6.C7.C8.B9.D10.A讲解:1.walkpast表示“走过去”。而pass是动词,表示“经过……”。2.tapsbontheshoulder意思是“拍某人的肩膀”,不能说taponhisshoulder,类似的表达法有:takesbbythehand拉某人的手,hitsbintheface打某人的脸。3.打扰对方或请求对方帮助时用“Excuseme”。4.beangryatsth“因某事生气”;beangrywithsb“生某人的气”。5.sometime一段时间sometime某时sometimes有时6.Iwonderifyoucoulddosth是一个句型,用来表达“不知您能否做……?”请求对方的帮助。例如:IwonderifyoucouldhelpmewithmyEnglish.不知您能否帮助我学英语。7.宾语从句为陈述句语序。8.根据上下文的意思,这个人是“不知道几点钟了”。9.时间+later=after+时间,表示一个过去时间的“多久以后”。例如:afewdayslater=afterafewdays几天以后。10.read的过去式与原形拼写相同,只是读音不—样。原形读作[ri:d],而过去式读作[red].本文是一篇记叙文,主要讲述了爷爷来美国的经历。71.bornbeborn是固定搭配,意为“出生”,故应填born。72.rich根据上文“poorpeople”从而可推断填rich。73.make/earn根据beeasytodosth.结构,可知此处应填一个动词的原形;make/earnmoney(挣钱)是固定短语,故此空
