B。saved C.willsave D.willhavesaved解析:句意：—Tommy正计划着买一辆车。—我知道。到下个月,他将攒够足够的钱买一辆二手车。由bynextmonth可知用将来完成时。答案:D。例2。—DidyouhavedifficultyfindingAnn’shouse?—Notreally.She_____uscleardirectionsandwewereabletofinditeasily。wastogive B.hadgiven C.wasgiving D.wouldgive解析：句意：-你们找到Ann的家有困难吗？-没什么困难.她已经给了我们清晰的指示，我们能很容易找到。本题考查动词时态。动词give的动作发生在"wereabletofind”之前,符合过去完成时表示“过去的过去“的用法.故选B项。答案：B。 例3.We_____forover2hours。Areyousurethisistherightway？Havebeendriving B.weredriving C。haddriven D.drove解析：句意：我们已经开了两个多小时了，你确定这条路对吗?本题考查动词的时态。根据题干可知到目前为止我们一直在开始，所以用现在完成进行时。答案:A.例4._____thepastyearasanexchangestudentinHONGKong，Lindaappearsmorematurethanthoseofherage.Spending B.Spent C.Havingspent D。Tospend解析：句意：作为一名交换生在香港度过一年后，Linda看起来比同龄人更成熟。本题考查非谓语动词作状语。分析题干可知，非谓语动词与其逻辑主语Linda之间为主动关系，所以排除B项；非谓语动词所表达的动作发生在句子谓语appears之前，所以用完成式，排除A项和D项，故答案为C项。答案:C.例5。（2015北京101中学高三测试）-WhatdoyouthinkoftheDidiDacheapps，Maria？-Theyarehandyforme。I_____privatecarsusingtheappsforhalfayear。havebeenhiring B。hired C.hadhired D.hire解析:句意为:Maria，你觉得“滴滴打车"这款手机应用怎么样？对我来说是方便的。我用这款使用现在完成进行时，表示“租用"这个动作从过去一直持续到现在而且还在进行。故答案选A。答案：A。基础演练一，根据句意，用括号内的词的正确形式填空。-TheChinesegovernmentistryingtoprotectthegiantpanda。-Iknow。By2020,they__________（add）about69。500squaremilesoflandtothecountry'snaturereservesystem.2。JustasIgottotheschoolgate,IrealizedI___________（leave）mybookinthecafé。3。Themanager___________(tell）theworkershowtoimprovetheprogramsince9am。4。___________(work）fortwodays，Stevemanagedtofinishhisreportonschedule.Keys：1.willhaveadded
