?3.WhatkindsofwordsorphrasescanbeusedinthePresentPerfectTense?現(xiàn)在完成時的用法:（1）表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在造成的影響或結(jié)果;（2）表示過去已經(jīng)開始，持續(xù)到現(xiàn)在的動作或狀態(tài).我們可以簡記為：過去對現(xiàn)在，過去到現(xiàn)在have/hasbeen和have/hasgone的區(qū)別：have/hasbeen表示“曾到過某地”；have/hasgone表示“到某地去了”

?，F(xiàn)在完成時常與already，just，yet，ever，never,before等連用.也可以和表示從過去某一時刻延續(xù)到現(xiàn)在（包括“現(xiàn)在”在內(nèi)）的一段時間的狀語連用，如for，since，sofar,now，today，thismonth，thisyear等.Discussion用所給動詞的適當(dāng)形式填空：1.Thenewspaperishere.It_______(come)amomentago.I______________(notread)ityet.2.I_______(lend)myCDplayertoheryesterday,butshe________________(notreturn)ittomeyet.3.Haveyou_________(borrow)thisbookbefore?Yes,I________(borrow)itlastweek.4.______you_______(copy)allthenewwords?Yes,I______(copy)themhalfanhourago.5.WhereisJack?–He________(go)swimmingalready.He______(go)out20minutesago.6.______you_______(see)thefilmbefore?Yes,I____.When_____you____(see)it?Amonthago.camehaven’treadlentborrowedhasn’treturnedborrowedcopiedcopiedhasgonewentHaveseendidhaveseeHave

現(xiàn)在完成時和一般過去時的比較（1）一般過去時表示過去某時發(fā)生的動作或單純敘述過去的事情，強(qiáng)調(diào)動作；現(xiàn)在完成時為過去發(fā)生的，強(qiáng)調(diào)過去的事情對現(xiàn)在的影響，強(qiáng)調(diào)的是影響。（2）一般過去時常與具體的時間狀語連用，如：yesterday,lastweek，…ago,in1980,inOctober,justnow…等.而現(xiàn)在完成時通常與just,already,ever,never,yet,

等副詞和for,since,sofar,thesedays等表示一段時間的狀語連用，或無時間狀語。（3）現(xiàn)在完成時可表示從過去持續(xù)到現(xiàn)在的動作或狀態(tài)，動詞一般是延續(xù)性的，例如：live,teach,learn,work,study,know…,一般過去時則沒有這一用法.Correctthemistakes:Thefilmhasbegunforhalfanhour.Thebabyhascaughtabadcoldsincelastnight.Hehasborrowedthemagazineforafewdays.Howlonghashejoinedthearmy?Thefilmhasbeenonforhalfanhour.Thefilmbeganhalfanhourago.Thebabyhavehadabadcoldsincelastnight.Thebabyhadabadcoldlastnight.Hehaskeptthebookforafewdays.Heborrowedthebookafewdaysago.Howlonghashebeeninthearmy?Howlonghashebeenamemberofthearmy.Whendidhejoinedthearmy?

關(guān)于瞬間動詞：1.瞬間動詞可以有現(xiàn)在完成時態(tài)，但不可以與表示一段時間的狀語連用，若要接一段時間，需要做一些相應(yīng)的變換：borrow—buy—die—open—close—leave—come—get/arrive—join—2.但是瞬間動詞的否定形式可以與表示一段時間的狀語連用。keephavebedeadbeopenedbeclosedbeawayfrombebeinbeamemberofeg.Hehasn’tcomehereforaweek.eg.Thedoghasbeendeadfortwodays.Hehaskeptthisbookforaweek.Fillintheform,usingdifferenttenses:1.HanMei_______toEnglandonceayear.(go)2.Lastyear,Jim_______toShanghai.(travel)3.We________nearly2000wordsbytheendofnextterm.(learn)4.Theoldman________onthelonelyislandallhislife.(live)5.SometimesMrGreen______MrSmithwithpresents.(visit)6.Nonews______goodnews.(be)7.Thefactory________________forseveralyears.(close)goestravelledwilllearnhaslivedvisitsishasbeenclosedExercisesGamesaquickanswer1234567TrueorfalseTherehashadalotofbigfactoriesinmyhometownsince1994.Therehasbeenalotofbigfactoriesinmyhometownsince1994.TrueorfalseI’msurethatwehaveseenthefilmago.I’msurethatwehaveseenthefilmbefore.What'sthedifferenceA.HehaslivedinBeijingfor8years.B.HelivedinBeijingfor8years.A句指的是到目前為止他在北京住了8年了，可能還會繼續(xù)住下去。B句指的是他在北京住過8年，現(xiàn)在不在北京了。MakesentencesJim,for,so,has,tonight,is,Shanghai,tomorrow,leaving,to,bed,early,go,he,to.
