初中现在完成时讲解练习及答案

现在完成时态与一般过去时态的区别1一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。Isawthisfilmyesterday.（强调动作发生的时间是yesterday。）Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了。）2一般过去时和表示过去的时间状语连用，如：…ago,lastweek/...In2008,inthepast,justnow,thedaybeforeyesterday,yesterday...Then(那时),thatday,oneday,once(从前)现在完成时常和recently（近来），ever,never,twice,sofar（到目前为止）,since，for，inthepast/lastfewyears,already（肯定句）,yet（否定，疑问句）,just(刚刚),before（以前）连用。3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live,teach,learn,work,study,know.3.用相应的延续性动词替换短暂性动词，句中谓语动词用现在完成时，时间状语为“for＋时间段”或“since＋时间点”。如：HehasbeenintheGreenChinaforthreeyears.HehasbeenamemberoftheGreenChinaforthreeyears.他加入“绿色中国”已经三年了。Theoldmandied4yearsago.----Theoldmanhasbeendeadfor4years.HejoinedtheParty2yearsago.----HehasbeeninthePartyfor2years.Iboughtthebook5daysago.----Ihavehadthebookfor5days.表示时间段的短语有:for+一段时间(for2years),since+从句(sincehecamehere),since+时间点名词(sincelastyear,since5daysago),howlong;foralongtime等。延续性动词和瞬间性动词之间的转化1.Hedied10yearsago.——He______________for10years/since10yearsago.2.Heborrowedthebook2weeksago.——He_____________thebookfor2weeks.3.Heboughtthemotorbikeamonthago.——He___________themotorbikeforamonth.4.Hearrivedherethreedaysago.—He____________heresincethreedaysago.5.Theyturnedoffthelight2hoursago.——Thelight__________for2hours.6.Helefthere2yearsago.———He____________fromherefor2years.7.Thefilmbegan30minutesago.——Thefilm__________for30minutes.8.Theyopenedthedooranhourago.——Thedoor__________foranhour.9.Theyclosedthedooranhourago.——Thedoor___________foranhour.一、用过去时或现在完成时填空：1.“_________you__________(have)lunch?”“Yes.”2\n“When________you__________(have)it?”“I____________(have)itat12:00.”2.“_________you__________(write)alettertoyourauntyet?”“Yes,I___________.I________________(write)onelastweek.”3.“_________he___________(finish)hishomework?”“Notyet.”4.“_________theyever__________(be)abroad?”“Yes,justonce.”5.Yourfather_________just___________(finish)hiswork.6.Yourfather_________(finish)hisworkjustnow.7.LasttermI__________(learn)manyEnglishwords.8.They____________(notread)theinterestingbooksyet.9.He_____________never____________(go)tothesciencemuseum.10.____________youever____________(drink)coke?11.Haveyou_____________(buy)adictionary?““Yes,I__________.”“Where______you___________(buy)it?”“I_________(buy)itinabookstore.”“When___________you_____________(buy)it?”“Yesterday.”二、用since和for填空1.______twoyears2._______twoyearsago3._______lastmonth4.______19995._______yesterday6._______4o’clock7.______4hours9._______wewerechildren11.______shelefthere12.HehaslivedinNanjing________theyearbeforelast.13.I’veknownhim__________wewerechildren.14.OurteacherhasstudiedJapanese_________threeyears.15.Shehasbeenawayfromthecity___________abouttenyears.16.It’sabouttenyears__________sheleftthecity.三、用have/hasbeento/in,havegoneto及go的各种形式填空。1)WhereisJack?He__________hiscountry.2)David________theparkjustnow.3)John_______Englandsincehecameback.4)Howlong_____have_____thisvillage?5)TheSmiths______Beijingforyears.6)_____youever____America?--Yes,I_____theremanytimes.7)I_____thisschoolsincethreeyearsago.8)WhereisJim?He_____thefarm.9)When_____he_____?He_______anhourago.10)Wouldyouliketo_____thezoowithme?---Yes,butI_____therebefore.11)Where_____you_____now?---I____thezoo.12)Heoften_____swimming.13)_____you______therelastyear?14)_____theyoften______skatinginwinter?2
