eg:Bothhisparentslooksad.Maybe

they____what'shappenedtohim.Ａ.knewＢ.haveknownＣ.mustknowＤ.willknow简析：现在完成时主要强调过去发生的动作对现在造成的影响，或过去发生的动作还未结束，一直持续到现在或将来，重点在于对现在的影响。这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。故上两侧根据上下文分析、推理，正确答案是Ｂ。Samgotsicktwodaysago.Samhasbeensickfortwodays.Sherrygotherdriver’slicense(执照)in1999.Sherryhashadherdriver’slicensesince(自从)1999.考点二：考查与一般过去时的区别例1.—ThesefarmershavebeentotheUnitedStates.

—Really?When___there?

Ａ.willtheygoＢ.didtheygo

Ｃ.dotheygoＤ.havetheygone例2.—______you___yourhomeworkyet?

—Yes.I_____itamomentago.

Ａ.Did;do;finishedB.Have;done;finished

Ｃ.Have;done;havefinishedＤ.will;do;finish简析：现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday,lastweek,amomentago等）连用。故例１、２的正确答案皆为B。考点三：考查词组have/hasbeenin/to与have/hasgoneto的区别

例1.MissGreenisn‘tintheoffice.she_______tothelibrary.

Ａ.hasgoneＢ.wentＣ.willgoＤ.hasbeen例2.Myparents______Shandongfortenyears.

Ａ.havebeeninＢ.havebeento

Ｃ.havegonetoＤ.havebeen简析：“have/hasgoneto+地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/hasbeenin+地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/hasbeento+地点”表示“曾经去过某地（但现在已不在那儿）。”故例1、2的正确答案皆为A。现在完成时三看三用一看时间状语。如果句中没有表示过去确切时间的状语，常用现在完成时；如果有，则只能用一般过去时。Ihavevisitedthefactory.Ivisitedthefactorylastyear.二看句首有无疑问词。如果笼统地问人家做过某事了吗（句首无疑问词），常用现在完成时；但进一步询问何时、何地、何原因、用什么方式做那事时（句首有疑问词）就要用一般过去时。－Haveyouhadyourbreakfast?－Yes,Ihave.－Whendidyouhaveit?－Atseventhirty.注意：这种用法是以连贯性问答为背景的。否则就需要具体情况具体分析。Howmanywordshaveyoulearnedbyheart?Howdidyoulearnthembyheart?三看句中谓语动词是否为延续性动词。如果表示的动作或状态一直延续到现在，最好选用延续性动词，并使用现在完成时；如果是瞬间动词，则用一般过去时。如：Hehasbeenaleaguememberfortwomonths.HejoinedtheYouthLeaguetwomonthsago.Exercises()1.You’veneverseensuchawonderfulfilmbefore,_______?A.haven’tyouB.haveyouC.doyouD.don’tyou()2.—Ihavewatchedthegame.—When____you____it?A.have;watchedB.do;watchC.did;watchD.will;watch()3.Mr.Green____inChinasincefiveyearsago.A.livedB.haslivedC.livesD.isgoingtolive()4.Hisgrandma______fortwoyears.A.diedB.hasdiedC.wasdeadD.hasbeendeadBCBD()5.–WhereisHanMeinow?－She____toShanghai.Shewillbebackintwodays.A.hasgoneB.hasbeenC.goesD.hadgone()6.－_____you____totheUnitedStated?－No,never,butIwenttoCanadaafewyearsagoA.Have;beenB.Have;goneC.Did;goD.Do;go()7.Youhaven’tchangedyourmind,_______?A.doyouB.areyouC.haveyouD.
