emarrybemarried他的爺爺已經(jīng)去世2年了。Hisgrandpahasbeendeadfor2years.Nick參軍3年了.Nickhasbeeninthearmyfor3years他離開深圳好長時間了。HehasbeenawayfromShenzhenforalongtime.這本書我已借了4個月了Ihavehad/keptthebookfor4months.五、現(xiàn)在完成時與一般過去時的區(qū)別(1)一般過去時的謂語動詞用過去式,而現(xiàn)在完成時的謂語基本構成是"助動詞have/has+過去分詞"。如:Thefilmstartedat7o'clock.Hehasbeenateacherformanyyears.
(2)一般過去時通常與表示過去的時間狀語連用。如:yesterday,lastweek,twoyearsago,justnow,in2002等;而現(xiàn)在完成時則常與just,already,ever,never等副詞和thesedays,thisweek,since...,for.../since...ago/uptonow/sofar等表示一段時間的狀語連用。(3)一般過去時表示過去某個時間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動作。說話的側重點只在于陳述一件過去的事情,不強調(diào)對"現(xiàn)在"產(chǎn)生的影響。如:HevisitedGuilinin1998.他1998年參觀過桂林。(只說明去桂林的時間)狀(4)語現(xiàn)連在用完。成時表示動作發(fā)生在過去,對現(xiàn)在造成了影響或產(chǎn)生了結果。不與確定的過去時間如:Jillhasboughtanewcomputer.吉爾買了一臺新電腦。(著重點是現(xiàn)在有了一臺新電腦)看看以下的幾組句子,有什么區(qū)別?(A)Haveyouseenthefilm?(B)Didyouseethefilm?[說明]你看過這部電影嗎?句強調(diào)的是被問者對劇情是否了解;句強調(diào)的是看這部電影的動作是否發(fā)生過,并不強調(diào)是否知道其內(nèi)容。(A)HehaslivedinBeijingfor8years.(B)HelivedinBeijingfor8years.[說明]他在北京住了8年。句講的是到目前為止他在北京住了8年,可能還會繼續(xù)在北京住下去。句講的是他在北京住過8年,現(xiàn)在不在北京了。練習一、抄寫動詞以及過去式和過去分詞。1.e3.go4.do5.have6.drink.7.give.8.eatbuildbite-—catchchoose■cut-_fall9.know10.run11.say.12.see.13.find3.go4.do5.have6.drink.7.give.8.eatbuildbite-—catchchoose■cut-_fall9.know10.run11.say.12.see.13.find14.drawfly-—forgetgrowhit-—hurtkeep15.get16.hear17.begin18.buy.lend-lose-meet-put19.leave.20become19.leave.20becomeread■ring-二、用for或since填空Mr.BrownhashadhisTV15years.I'vetakendrivinglessonslastmonth.Mysisterhashadhercellphoneamonth.Myfriendshaven'tvisitedmemybirthday.Wehaven'tusedourcaralongtime.Shehasn'thadagoodcupofcoffeeyears.Tomhaswornglasseshewas7yearsold.JillhasbeeninIrelandMonday.Mr.JasonhasbeeninParisthreedays.MyaunthaslivedinAustralia15days.Margaretisinheroffice.Shehasbeenthere7o'clock.Indiahasbeenanindependentcountry1974.Nobodylivesinthosehouses.Theyhavebeenemptymanyyears.Mikehasbeenillalongtime.HehasbeeninhospitalOctober.三、改寫句子,使原句的意思不變,每空一詞。TheEnglishprofessorarrivedhereaboutaweekagoTheEnglishprofessorhereforaboutaweek.Herhusbandstartedtoworkonthefarmthreehoursago.Herhusbandonthefarmforthreehours.TheFrenchmusiciancametoChinalastmonth,andheisstillhere.TheFrenchmusicianChinaforamonth.Hejoinedthearmyin1985.Hethearmy1985.HejoinedtheLeaguehalfayearago.HehasbeenaLeaguehalfayear.Thebusleftfiveminutesago.Thebusalreadyforfiveminutes.ThegirlboughtanewschoolbaginSeptember.ThegirltheschoolbagsinceSeptember.Theshopclosedlastwinter.Theshopsincelastwinter.Thefilmbegantenminutesago.Thefilmfortenminutes.Thedogdiedtwodaysago.Thedogfortwodays.Themeetingendedlastmonth.Themeetingforamonth.四、用have/hasbeento,have/hasgoneto填空:—Whereisyourbrother?一Hetheshop.He'llbebacksoon.一—youevertoAmerica?一Yes,INewYorktwice.—Hereyouareatlast!Whereyou?—ILondon.一DavidAustralia.一I'msurehe'salreadyarrived.—IsBennyhere?—No,hetheschoollibrary.Heleftfiveminutesago.
