模块语法聚焦九,模块语法聚焦九,语法点击,whether/if及疑问词引导的宾语从句本模块主要学习另外两类宾语从句whether或if引导的宾语从句和疑问词引导的宾语从句。一、whether或if引导的宾语从句1.whether/if引导宾语从句时，意为“是否”，表示不确定的概念，常位于ask,see,say,know,findout等词或短语的后面。一般情况下，两者可互换，在口语中多用if。例如：Nobodyknowswhether/ifitwillraintomorrow.没有人知道明天是否会下雨。Lucyaskedwhether/iftheyhadacottonsweater.露西问他们是否有棉制的毛衣。,2.whether/if引导宾语从句时，要注意三方面，即连词、语序和时态。(1)whether/if在句中不能省略。例如：Idontknowif/whetherhewillcomeheretoday.我不知道他今天是否会来这儿。(2)whether/if引导的宾语从句，其从句的语序应用陈述语序。例如：Didyouknowthewaytothehospital?Theoldwomanaskedme.Theoldwomanaskedmeif/whetherIknewthewaytothehospital.那位老妇人问我是否知道去医院的路。,模块语法聚焦九,(3)whether/if引导的宾语从句，其时态应和主句的时态保持一致。即当主句为一般现在时态时，从句可根据实际情况选择不同的时态；当主句为一般过去时态时，从句一般使用相应的过去时态。例如：Idontknowif/whetherhehascomehere.我不知道他是否已经来这儿了。Tomaskedif/whetherIhadreadthebook.汤姆问我是否读过这本书。,模块语法聚焦九,3.whether/if的区别：(1)在动词不定式之前只能用whether。例如：Icantdecidewhethertostay.我不能决定是否留下。(2)在固定结构“whetherornot”中，只能用whether。例如：Iwanttoknowwhetheritsgoodnewsornot.我想知道它是否是好消息。(3)在介词后只能用whether。例如：Hisfatherisworriedaboutwhetherhemaylosehisjob.他的父亲担心他是否会失去工作。,模块语法聚焦九,二、疑问词引导的宾语从句1在引导词上，要将疑问代词或疑问副词变为连接代词或连接副词，引导宾语从句。例如：Whosebikeisthis？Doesanybodyknow?Doesanybodyknowwhosebikethisis?2在时态上，宾语从句的时态应与主句的时态保持一致。例如：Whenwillthetrainarrive？Heaskedme.Heaskedmewhenthetrainwouldarrive.3在语序上，要将疑问语序改为陈述语序。例如：Whichonedoyoulikebest？Sheaskedme.SheaskedmewhichoneIlikedbest.,模块语法聚焦九,注意：疑问句中主语之前的助动词若是do/does/did，变为宾语从句时，要先将其去掉，谓语动词再根据时态作相应的变化。4特殊疑问词在句中作主语，变为宾语从句时，语序不变(时态应作相应变化)。例如：Whocananswerthequestion？Theteacherasked.Theteacheraskedwhocouldanswerthequestion.5特殊疑问句变为宾语从句后，用问号还是用句点完全取决于主句的句式：如果主句为陈述句或祈使句，句末就用句点；如果主句是疑问句，句末就用问号。例如：Idontknowwhenweshallstarttomorrow.Doyouknowwhenweshallstarttomorrow?,模块语法聚焦九,实战演练,.单项填空()1.2015南京IsawDavidintheteachersofficethismorning.Doyouknow_hewasthere?Hewenttheretohandinhishomework.AhowBwhetherCwhenDwhy()2.2015泰安Couldyoupleasetellme_youwillgotoHongKongonbusiness?Sure.Iprefertotakeaplane.AwhetherBwhyCwhenDhow()3.Idontknow_ornottheywillcometohelpus.AwhetherBifCthatDwhen,答案1.D2.D3.A,模块语法聚焦九,()4.2015青岛Iwonder_AhowwillyoucelebrateThanksgivingBthattheWaterFestivalisreallyfunCwhatdopeopleeatontheMidAutumnFestivalDwhetheryouwillmakeresolutionsonNewYearsDay,解析D在宾语从句中，从句用陈述语序，排除A和C；又由主句中“wonder”可知选D。,模块语法聚焦九,()5.2013黔东南Ourphysicsteachertolduslight_fasterthansound.A.travelsBtravelledCtravellingD.totravel()6.2014滨州Excuseme,canyoutellme_？A.whendoestheplaneleaveB.howlongtheplanehasleftC.whentheplaneleavesD.whendidtheplaneleave,答案5A6.C,模块语法聚焦九,()7.Couldyoutellme_ameetinginGuangzhounextweek?A.iftherewasgoingtobeB.ifthereisgoingtobeC.whetheristheregoingtobeD.whetherthereisgoingtohave,答案B,模块语法聚焦九,()8.2015昆明Theprojectissodifficultforyourcousin.Yes,Iamwondering_AthathewillfinishitontimeBwhetherhecanfinishitbyhimselfChowcouldIhelphimoutDcanIdoanythingnecessaryforhim,解析B句意：“这个工程对于你的表弟来说实在是太难了。”“是的，我想知道_。”wonder是动词，后面用宾语从句，宾语从句要用陈述语序，排除C、D，根据句意可知选B。,模块语法聚焦九,.按要求完成下列各题1Wouldshefinishherhomeworkintwohours?Shewasntsure.(合并为一句)Shewasntsure_shewouldfinishherhomeworkintwohours.2Thechildrenaskedtheirmother.Canweeatthoseapples？(合并为一句)Thechildrenaskedtheirmother_eatthoseapples.,if/whether,if/whethertheycould,模块语法聚焦九,32014兰州Tomsaid,“Wewillgobacktomorrowmorning.”(改为间接引语)Tomsaidthey_comebackthenextmorning.42014黔西南“Whoisresponsibleforthefoodsafetyproblem?”askedthereporter.(改为间接引语)Thereporterasked_responsibleforthefoodsafetyproblem.,would,whowas,模块语法聚焦九,.用适当的连接词填空1Icanthear_theyaretalkingaboutoverthere.2Themotheraskedherson_hehadlunch.3Doyouknow_bikeitis?MaybeitsLucys.4Couldyoutellme_yourfatherisathomeornot?5Shetoldme_shewouldgotoShanghainextweek.,whose,what,if/whether,whether,that,模块语法聚焦九,.将下列句子变成宾语从句1Whenwilltheplanearrive?Pleasetellme.Pleasetellme_.2Whatareyouinterestedin?Couldyoutellme?Couldyoutellme_？3Istherelifeonotherplanets?Nooneknows.Nooneknows_.4Whichmoviedoeshelikebest?Le
