文档简介
一、时态讲解:现在完成时(1)构成:现在完成时由助动词have+过去分词构成,助动词have有人称和数的变化。第三人称单数用has,其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study为例,其否定式、疑问式和简单回答形式如下:否定式疑问式Ihavenot(haven't)studied..HaveIstudied.?Youhavenot(haven't)studied..Haveyoustudied.?Hehasnot(hasn't)studied..Hashestudied.?否定疑问式简单回答(肯定/否定)HaveInot(Haven'tI)studied.?Yes,youhave.No,youhaven't.Haveyounot(Haven'tyou)studied.?Yes,Ihave.No,Ihaven't.Hashenot(Hasn'the)studied.?Yes,hehas.No,hehasn't.2)用法:现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。Mydaughterhasjustgoneout.我女儿刚出去。I'msurewe'vemetbefore.我肯定我们以前见过面。Shehasarrived.她到了。表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently,already,just,lately,for..since...,yet等。如:Ihaven'theardfromherthesedays.这些日子我没有收到她的信。Wehaven'tseenyourecently.最近我们没有见到你。Theyhavebeenawayfortwoyears.他们离开已经两年了。ShehasbeenwithussinceMonday.★注意:a)since和for的区别since后接时间点,如1993,lastterm,yesterday,thetimeIgottherefor后接一段时间,表示“长达多久”,如tenyears,awhile,twodays等。Exercise:用since和for填空JimhasbeeninIrelandMonday.JillhasbeeninIrelandthreedays.HisaunthaslivedinAustralia15days.Maryisinheroffice.Shehasbeenthere7o'clock.Indiahasbeenanindependentcountry1974.Thebusislate.They'vebeenwaiting20minutes.Nobodylivesinthosehouses.Theyhavebeenemptymanyyears.Mikehasbeenillalongtime.HehasbeeninhospitalOctober.2)表示短暂意义的动词如arrive,leave,borrow,buy,begin,start,die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说:Hehascomeherefor2weeks.xTheoldmanhasdiedfor4months.xTheyhaveleftonlyfor5minutes.x以上三句话可以改为:Hehasbeenherefor2weeks.Theoldmanhasfor4months.Theyhaveonlyfor5minuteshave(has)been和have(has)gone的区别:表示“曾到过某地”要用“have(has)been”;表示“已经去某地”要用“have(has)gone”。试比较:Wherehashebeen?他刚才到哪里去了?(已经回来了)Wherehashegone?他上哪儿去了?(人不在)TheyhavebeentoCanada.他们到过加拿大。(现在已经不在加拿大)TheyhavegonetoCanada.他们到加拿大去了。(可能在路上和已经到加拿大).现在完成时不能和表示过去的时间状语连用,如yesterday,lastyear,in1976,twodaysago,justnow,whenIcamein,但可以和already,yet,sometimes,always,often,before,lately,recently,once,twice,ever,never等连用。例如:Shehasalreadycome.她已经来了。Ihaven'treadityet.我还没读过这个。Ihavemethimbefore.我从前曾见过他。MaHonghasalwaysbeenagoodstudent.马红一直是个好学生。Ihaveoftenseenhiminthestreet.我经常在街上看见他。TheyhaveneverbeentoYan'an.他们从未去过延安。Ihaven'tseenhimlately.我近来没看到他。irreguiarVerbsBaseFormPastFormPastParticiplebearborebornbeatbeatbeatenbecomebecamebecomeblowblewblownbringbroughtbroughtbuildbuiltbuiltbuyboughtboughtcatchcaughtcaughtchoosechosechosencomecamecomedodiddonedrinkdrankdrunkdrivedrovedriven
