加以強(qiáng)調(diào)或說明。而一般過去時(shí)則表示在過去某一具體時(shí)間發(fā)生的事情。IhavejustbeentoLondon.Iwenttherelastmonth.Ihavealreadyfinishedmyhomework.Ifinisheditanhourago.在沒有明確的過去時(shí)間狀語時(shí)，如何判斷該用現(xiàn)在完成時(shí)還是一般過去時(shí)呢？判斷的標(biāo)準(zhǔn)是看該行為是否對(duì)現(xiàn)在有影響，也就是說該句強(qiáng)調(diào)的是什么。試看以下對(duì)話：A:Wherehaveyouputmybook?Ican’tfindit.

你把我的書放在哪兒了？我找不到。B:Iputitonyourdeskyesterday.我昨天放在你桌子上了。該對(duì)話中，當(dāng)A問對(duì)方把自己的書放在何處時(shí)，A強(qiáng)調(diào)的是現(xiàn)在找不到了，因此用現(xiàn)在完成時(shí)。但是B回答時(shí)只是說明當(dāng)時(shí)放的位置，所以用一般過去時(shí)。再看下面的對(duì)話：A:Wouldyouliketogoandseethefilmwithmetonight?B:Sorry,Ihaveseenitalready.(不好意思，我已經(jīng)看過那部電影了)對(duì)話中的現(xiàn)在完成時(shí)表示對(duì)結(jié)果的強(qiáng)調(diào)：“電影已經(jīng)看過了，所以不想再看了”并非所有for作為時(shí)間狀語的句子都用現(xiàn)在完成時(shí)搞清一般過去時(shí)和現(xiàn)在完成時(shí)的區(qū)別。Iworkedhereformorethantwentyyears.(我現(xiàn)在已經(jīng)不在這里工作了)Ihaveworkedhereformorethantwentyyears.（現(xiàn)在我仍在這里工作）疑難點(diǎn)二：疑難點(diǎn)三：短暫性動(dòng)詞在現(xiàn)在完成時(shí)中的應(yīng)用要點(diǎn)（1）在現(xiàn)在完成時(shí)中，短暫性動(dòng)詞一般不能與時(shí)間段連用，但在否定句中，則一般可以和表示一段時(shí)間的for短語連用。（2）短暫性動(dòng)詞不能和表示一段時(shí)間的時(shí)間狀語連用。如果要保留表示一段時(shí)間的時(shí)間狀語，必須將短暫性動(dòng)詞轉(zhuǎn)換為延續(xù)性動(dòng)詞，常見的短暫性動(dòng)詞轉(zhuǎn)換為延續(xù)性動(dòng)詞如下：短暫性動(dòng)詞延續(xù)性動(dòng)詞fallasleepbeasleepbegin/startbeonbuyhavediebedeadcomebeinarrivebeherejoinbein/beamemberoffinish/endbeoverleavebeawayborrowkeepbegintostudystudycomebackbebackgettoknowknow1.---HowlonghasrobertD?-----Since2004.beentoBeijingB.becomeapolicemanJoinedtheartclubD.studiedinthisschool2.Mr.GreenAfromhishometownfor3years.HasbeenawayB.hasgoneHasleftD.hascome----Whendidyouleavehome?----Ilefthomeat18,Nile.ICyourcityforfiveyears.havegonetoB.havebeentoHavebeeninD.havecometo----DoesJimmystillworkasadriver?----No.HehasCfortwoyears.leftthecompanyB.gonetoShanghaiC.studiedincollegeD.losthisjob完成下列習(xí)題：辨析havebeento和havegonetoMyfatherhasgonetoShanghaiforameeting.他（已經(jīng)）去了上海。MyfatherhasbeentoShanghaiforameeting.他（曾經(jīng)）去了上海。ShehasbeentoChina.
