第二章第三节 难点类 1 条件关系

第二章第三节1条件关系题型特点正确识别真实条件句和非真实条件句（即虚拟语气）。真实条件句实现的可能性较大。非真实条件句实现的可能性较小或表示与事实相反的情况和事实，即动词为肯定形式的虚拟条件句实际表达否定的概念，反之亦然。在听的过程中，首先要判断if从句是真实条件句还是虚拟条件句。如果是虚拟条件句，一定要搞清楚它所表示的时间。常见句型If,unless,suppose,ifonly,incase,asif,aslongas,wouldrather,lest等引导的从句。With/without等引导的短语。解题小窍门1.条件关系听力题难在辩认非真实条件句，不过有一个简单诀窍可以比较好地解决这个问题。如果主句是将来时，if条件从句也是将来时，则是真实条件句，这意味着句子里说的是什么就是什么。除了这两种形式外，其它形式的句子都是非真实条件句，也就是说句子说的内容恰好和真实情况相反。Youwillcatchtheschoolbusifyougetupearly.（真实条件句）Ifitshouldraintomorrow,wewouldstayhome.（非真实条件句，真实的情况是明天不太可能下雨）2.除了上面的诀窍外，知道一些其它表达真实条件句和非真实条件句的形式对于提高答题正确率是很有帮助的。能引导真实条件句的还有：as(so)longas,unless,suppose,supposing,Let’ssay。由Ifonly开头的单句是真实条件句。3.最后还有一个小窍门供大家参考：如果一句话的谓语动词部分含有“would”、“might”一类的词，这句话十有八九是非真实条件句。Amorefriendlypersonwouldhaveavoidedhurtingpeopledlikethat.是非真实条件句。解题技巧我们在真实条件句的把握上往往问题不大。而最易十分之处就在于虚拟语气，借虚拟语气体的一个固定思路就是“反着选答案”。虚拟语气的一个常犯错误就是时态问题。我们需要牢记虚拟语气三种时态的基本形式。从句谓语主句谓语与现在事实相反were,didwould(should,could,might)+v与将来事实相反shoulddowould(should,could,might)+v（可能性极小）were+to+v与过去事实相反haddonewould(should,could,might)+havedone1.A.Askforachecktocoverdifference.B.BuyanewTVset.C.AsksomebodyelsetorepairhisTV.D.Mr.SmithisthebestpersontoaskforrepairingTVsets.2.A.ProfessorSmith‘scourseisdifficult.B.ProfessorSmithoftenmakesmistakes.C.ItiseasytopasstheexamgivenbyProfessorSmith.D.ProfessorSmithiseasytoplease.3.A.It’stoobadwedidn’tscoreanotherpoint.B.Ourteamisthebestonebyfar.C.Wewonaveryclosegame.D.Theirteamdidn’tgetasinglepoint.4.A.Hewantstodowhateverthecommitteeasksofhim.B.Hewantstomakedecisionsinagreementwiththecommittee.C.Hewantstorunthecommitteeaccordingtohisownideas.D.Hewantstoelectthecommittee’schairmanhimself.5.A.Bringhersomewater.B.Buyhersomeplants.C.Waterherplantswhilesheisaway.D.Waterherplantswhileheisonthevacation.6.A.Hedidn’tgotothedrugstore.B.Hecouldn’tgetthemedicine.C.Helearnedthatthedruggisthadbeenrobbed.D.Hehadalongwaitbeforethedruggistarrived.7.A.Totypeforawhile.B.Topickherup.C.Toreachthecorner.D.Todrivehome.8.A.Ifthereisapolicecar,hewilldrivefaster.B.Hecan’tseethepolicecarifhedrivesfaster.C.Ifitweren’tforthepolicecar,he’dbeabletodomorethan50.D.Heisdoingmorethan50.9.A.Tosavehermoneyforalongtime.B.Tobuyanewcar.C.Topurchaseausedcar.D.Togetasecondhandcar.10.A.Heisgoingtowatchtheplay.B.Heisgoingtodosomework.C.HeisgoingtowatchTV.D.Heisgoingtohavearest.11.A.Theman’sbestfriendisMary.B.Marygetsalongwellwithherfriends.C.Maryisn’tpopularamongherfriends.D.ThemanhasmorefriendsthanMary.12.A.Themanwillcomewithher.B.Shehastoomuchwork.C.Shepromisedherself.D.Noworkisduethenextday.13.A.Shewouldgohomeimmediatelyafterwork.B.Shewouldgotoaparty.C.Shewouldworkovertime.D.Shewouldworkearlyinthemorning.14.A.Thewomanknewnothingaboutwhathappenedtohim.B.Thewomanwenttohelphimimmediately.C.Themancomplainedaboutherignoranceofhiswords.D.Themandidn’t’needanyhelpfromher.15.A.Themanwillhelpher.B.Themandidn’thelpher.C.Themanhashelpedher.D.Themanwouldhavehelpedherifshehadneeded.16.A.ThemanissurethatSuehasfinishedherhomework.B.ThemanissurethatSuehasn’tfinishedherhomework.C.ThemanisnotsurewhetherSuefinishedherhomeworkyesterday.D.ThemanissurethatSuewilljointhem.17.A.Tomrefusedtogivethemanapainting.B.Tomrefusedtoaccepttheman’spainting.C.Themandidn’taskforTom’spainting.D.Themandidn’tappreciateTom’spainting.18.A.Theyarrivedatthehoteljustintime.B.Theyfoundthehotelfull.C.Theywouldgotootherhotels.D.Theyhadtogotootherhotels.19.A.Shehasacquiredadriver’slicense.B.Shehassoldalotoftickets.C.Shehasbeenacceptedbyacollege.D.Sheisgoingtoaforeigncountry.20.A.Shedoesn’tlikeeitherofthem.B.JohncopieditfromJim.C.JimcopieditfromJohn.D.Oneisthecopyfromtheother.
