现在完成进行时1定义:现在完成进行时表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去。2现在完成进行时的构成:现在完成进行时是由“have/has+been+动词的现在分词”构成3现在完成进行时的基本句型肯定式I/Wehavebeenworking.疑问式Haveyoubeenworking？简略回答Yes，I/wehave.No，I/wehaven't.肯定式He/She/Ithasbeenworking.疑问式Hashe/she/itbeenworking？简略回答Yes，he/she/ithas.No，he/she/ithasn't.4现在完成时的用法1）在强调指出动作还未结束，还要继续下去。如：I'vebeenreadingthisbookfortwohours，butIhaven'tfinishedit.这本书我已读了两个小时了，但我还没读完。I'vereadthisbook.我已读完这本书了。2）强调动作延续时间的长久或带感情色彩。Shehasalwaysbeenworkinglikethat.她一贯是这样工作的。3）现在完成进行时也可表示现在以前这段时间反复发生的事情。We'vebeenseeingquitealotofeachotherrecently.最近我们经常见面。5现在完成时和现在完成进行时的区别1）现在完成进行时更强调动作的延续性,它是现在完成时的强调形式。试比较：We'vebeenlivingherefortenyears.We'velivedherefortenyears.我们在这儿已经住了十年了。2）在不用时间状语的情况下，现在完成进行时表示动作仍在进行。而现在完成时则表示动作在过去已结束。如：Thestudentshavebeenpreparingfortheexam.（还在进行）学生们一直在准备考试。Thestudentshavepreparedfortheexam.（已经结束）学生们为考试作了准备。3）有些表示状态，感情，感觉的动词如：have，exist，like，hate，hear，know，sound等动词不能用于现在完成进行时，但可用于现在完成时。如：They'veknowneachothersince1970.自从1970年起他们就相互认识了。练习:1.MrLiswimmingfor3hours,andhissonanhourago.A.hasbeen,startedB.havestarted,hasstartedC.started,startedD.Hasstarted,hasstarted2.---Howlongyoustamps?---Sincetwoyearsago.1A.have,collectB.have,beencollectingC.did,collectD.are,collecting3.Shehadaheadachebecauseshetoolong.Sheoughttoshop.A.hasbeenreadingB.hadreadC.isreadingD.read4.TheboyTVallthemorning.A.haswatchedB.hadwatchedC.hasbeenwatchingD.watched5.---haveyoubeenlearningtoswim?---Halfayear.A.HowlongB.HowoftenC.HowfarD.When6.Ourteacherhasbeenteachinginthisschoolfor.A.twoyearandahalfB.twoandahalfyearC.twoyearsandhalfD.twoandahalfyears7.Heitfortwohours,andhe'sstillwatchingnow.A.hasbeenwatchedB.watchingC.hasbeenwatchingD.iswatching现在完成时态练习题答案一．翻译下列句子：1.Haveyoueverhad/eatenfishandchips?2.Ihavejustlostmychemistrybook.3.Ihaveneverbeentothefarmbefore.4.Hehasalreadyhadlunch=Hehashadlunchalready.5.Haveyouseenthemovieyet?6.Mybrotherhasn’tcome/get/beenbackyet=Mybrotherhasn’treturnedyet.7.Ihavehadthisdictionaryforthreeyears/sincethreeyearsago.8.HasbeenawayfromChinaforthreeyears.9.Ihaveknownthemforfiveyears.10.TheyhavebeenintheUSAforfiveyears.11.HehasbeenheresincehemovedtoJining.12.Mysisterhasbeenacollegestudentforthreeyears=Mysisterhasbeenincollegeforthreeyears.13.Theyhaveknowneachothersince1999.14.Ihavebeeninthisschoolforoverthreeyears.二、用since或者for填空1.for2.since3.since4.since5.since6.since7.for8since9.since10.since11.since12.since13.since14.for15.for16.since四、划线提问1.Howlonghave,beenthere2.Howlonghas,livedhere3.Whendid,leavehere4.Whendid,buy五、用have(has)been或have(has)gone填空。A:WherehasLiFeigone?B:HehasgonetoHainanIsland.A:Howlonghashebeenthere?B:Hehasbeenthereforthreedays.A:Whenwillhecomeback,doyouknow?B:I’mafraidhewon’tcomebackrecently.A:CouldyoutellmethewaytoHainanIsland?2B:Sorry,Ihaveneverbeenthere.A:HowmanytimeshasLiFeibeentothatplace?B:Hehasbeenthereonlyonce.六、用have/hasbeento/in,havegoneto及go的各种形式填空。1.hasgoneto2.wentto3.hasbeenin4.have,beenin5.havebeenin6.Have,beento;havebeen7.havebeenin/at8.hasgoneto9.didgo;went10.go;havebeen11.are,going;amgoing12.goes13.Did,go14.Do,go七、综合练习:1.never2.just,already3.for4.ever,never5.yet,just/already八.用适当的时态填空：1.lived/hasbeenliving2.havebeen3.went4.haspassed;left5.haslost;have,seen6.Have,found7.have,had8.have,returned9.Have,built10.haven’tfinished11.hasread12.bought13.lost14.havebeenreading/hasread3
