宾语从句的讲解(两课时)一、教学目标（一）了解宾语从句的定义和结构（二）掌握宾语从句的引导词及其用法（三）注意宾语从句中时态，语序，标点符号，简化及否定转移的问题二、教学重点：1.在复合句中起宾语作用的从句叫做宾语从句.2.宾语从句的引导词A由that引导的宾语从句，连词that只起连接作用，在从句中不做句子的成分，也无词汇意义，通常可省略例：Weknow(that)weshouldstudyhard.注意事项：在以下情况中that不能省略1）当句中的动词后接两个或两个以上由that引导的宾语从句时，第一个that可省，但后面的that不可省。例句：Hesaid(that)youweretooyoungtounderstandthematterandthathewasaskednottotellyou.2）当that从句是双宾语中的直接宾语时，that一般不可省略。例句：Ican’ttellhimthathismotherdied.B由连词if、whether引导的表示“是否…”的宾语从句。whether,if在从句中不做句子的成分，一般情况下，whether和if可以替换。例：Idon’tknowif/whetherhewillcometomorrow.Theteacheraskedif/whetherwehadfinishedtheexperiment.注意事项：在以下情况中只能用whether1)在介词后面的宾语从句中不用if引导例：Everythingdependsonwhetherwehaveenoughmoney。2)宾语从句中有ornot时不用if引导.例：Idon’tknowwhetherthemoviestarwillcomeornot.3)和不定式连用作宾语时不用if引导.例：Idon’tknowwhethertostayherefordinner.4)whether放句首时不用if引导例：Whethertheywilljoinusinthepicnic,Idon’tcare.C由wh-引导的宾语从句。连接代词who,whom,whose,what,which,和连接副词when,where,why,how等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的成分。例：Youmusttakebackwhatyousaid.(what做宾语)Idon’tknowwherehelives.(where做地点状语)3.宾语从句中需注意的问题1）时态A主句是现在的时态，从句时态不受限制，并根据实际情况定。例：Ihear(that)Tomwillcomebacktomorrow.ShesaysJimwenttoworkanhourago.B主句是过去的时态，从句也要用过去的时态。例：Hesaid(that)hehadhadsupperalready.Hesaid(that)hewasreadingabook.C如果从句说明的是客观存在的事实或真理，从句不受主句限制，一律用一般现在时。例：Myfathertoldmethatnonewsisgoodnews.Hesaid(that)thesunismuchbiggerthanthemoon.2)宾语从句的语序宾语从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分例：Ibelievethattheywillcomesoon.HeaskedmewhetherIwasateacher.Iwanttoknowwhowentthere.3)标点符号由主句决定，不受从句限制。例：Doyouknowwhoheis?Webelievewewillwin.4)在think,believe,suppose,expect等动词引起的宾语从句中，如果主句主语是第一人称，谓语尽管是否定意义，却不用否定形式，而将think等动词变为否定形式。例：Idon’tthinkyouareright.(我认为你做的不对)5）宾语从句与简单句的交换。由连接代词和连接副词引导的宾语从句，如果宾语从句的主语和主句的主语是同一个人时，可以用“疑问词+不定式例：Idon’tknowwhatIshoulddonext.Idon’tknowwhattodonext.Hedidn’tknowwherehewouldlive.Hedidn’tknowwheretolive.宾语从句专项训练一基础题1.DoyouknowIcouldpasstheexam?A.thatB.whetherC.whatD.which2.Couldyoutellmesheislookingfor?A.thatB.whoseC.whoD.which3.It’suptoyoutodecideyou’llgothere,byairorbyroad.A.howB.whyC.thatD.when4.GuessIdidyesterday!A.whereB.whenC.whatD.which5.IknewthatthesunintheeastwhenIwasveryyoung.A.willriseB.roseC.riseD.rises连接成为含有宾语从句的复合句。1)TheseflowersarefromGuangdong.Hesaid.Hesaid_______theseflowers_______fromGuangdong.2)Lighttravelsfasterthansound.Myteachertoldme.Myteachertoldme_____light_______fasterthansound.3)Therewillbeameetinginfivedays.Jackdidn’tknow.Jackdidn’tknow______there__________ameetinginfivedays.4)CantheyspeakFrench?Iwanttoknow.Iwanttoknow___________________________French.5)Arethechildrenplayinggames?Tellme.Tellme______thechildren____________games.6)Haveyoufinishedyourhomeworkyet?Mr.ZhaoaskedMaChaoMr.ZhaoaskedMaChao______________________________homeworkyet.7)Howmanypeoplecanyouseeinthepicture?Whoknows?Whoknows_____________________________inthepicture?8)Wheredidsheparkhercar?Doyouknow?Doyouknow______________hercar?9)Whatdoesheoftentalkabout?Thegirlwondered.Thegirlwondered__________often________about.10)Whoknockedatthedoorsoloudly?Idon’tknow.Idon’tknow______________atthedoorsoloudly.11)Doeshestillliveinthatstreet?Idon'tknow.Idon'tknow______hestill_______inthatstreet.12)What'shisname?Iaskedhim.Iaskedhimwhat____________________.13)Whendoesthetrainarrive?Pleasetellme.Pleasetellme__________________________________.14)Dotheywantfriedchicken?Heaskedtheboys.Heaskedtheboys_____they_____friedchicken.15）WasthewatchmadeinShanghai?Idon'tknow.Idon'tknow_______thewatch_______madeinShanghai.
