宾语从句语序：陈述句语序主句+连接词+主语+谓语+其他成分.宾语从句用法宾语从句需注意，几点事项应牢记。一是关键引导词，不同句子词相异。陈述句子用that；一般疑问是否（if,whether）替；特殊问句更好办，引导还用疑问词。二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。三是语序要记清，从句永保陈述序。Weknowhim．WeknowhelikesEnglish.主s主s谓v谓v宾o宾o宾语从句就是由一个句子来构成主句的宾语主s谓v宾o简单句复合句一什么是宾语从句？试比较宾语从句的概念在句子中起宾语作用的从句叫做宾语从句。WeknowMrGreenteachesEnglish.Sheaskediftheseanswerswereright.Couldyoupleasetellmewheretherestroomsare?二、宾语从句三要素：连接词语序时态1.连词that引导：作从句的原句是陈述句。Ihear（that）Englishisnoteasy.2.if/whether“是否”，用它引导从句，说明对陈述的事物不明确或不清楚。常用在ask,wonder,can(could)youtellme等后。原句为一般疑问句，选择疑问句或反意疑问句。Couldyoutellmeif(whether)MissBrownlivesinthathouse?3.当从句原本是特殊疑问句时，用以下连接代词和连接副词引导：what,which,who,whom,whose,when,where,how,why,howfar,howlong,howmany,howmuch,howoften…作用：连接主句和从句，并在从句中担任句子成分，具有一定的意义。eg:Ididn’thear__what__hewantedmetodo.Iwanttoknow__who__isthatyoungman.Tomaskedus__when__wewouldstarttheparty.宾语从句连接词:1.陈述句2.一般疑问句3.特殊疑问句thatif/whether原有的特殊疑问词做连接代词和连接副词1.Ihear(that)_______________________.2.Hesaid(that)______________________.3.Theteachertoldus(that)_______________________________.hewillbebackinanhourhemissedusverymuchtheearthmoves1·由that引导的宾语从句注：that在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。aroundthesun二·语序：陈述句语序We’llhaveexamsnextFriday.UsingsayIcanhelphim.Theteachersays(that)we’llhaveexamsnextFriday.Thegirlsays(that)shecanhelphim.连词that不能省略的几种情况在由that引导的宾语从句中，由于连词that只起引导功能，无具体意义，不担当任何成份，因此在口语或非正式的文体中常可省略。然而，大凡规则总有例外的情况，在下列that引导的宾语从句中，that则不能省略。1.从句的主语是that。如：Hesaysthatthatisarealking’shat.他说那是一个真的王冠。2.that从句中含有主从复合句。如：I’mafraidthatifyou’velostit,youmustpayforit.3.主、从句之间有插入语时。如：Itsayshere,onthiscard,thatitwasusedinplays.卡片上写着，它是古代演戏用的。4.若出现两个或两上以上的由that引导的宾语从句，且由并列连词连接时，只有第一个连词that可以省略。如：Shesaid(that)shewouldcomeandthatshewouldalsobringherson.她说她要来，还要带她的儿子来。IsJimin?Hasshetakenanymedicine?UsingwonderLiLeiwondersifJimisin.Thedoctorwondersifshehastakensomemedicine.2.由if/whether引导的一般疑问句变宾语从句一般疑问句变宾语从句的步骤：1、把句子变为肯定句1.IsJimathome?Jimisathome.2.IsJuneagoodtimetovisitHongKong?JuneisagoodtimetovisitHongKong.3.Doeshelikesports?Helikessports.4.Willtheyplaybasketballafterschool?Theywillplaybasketballafterschool.变化方法：主句+if/whether+一般疑问句。if/whether引导宾语从句，表示“是否”之义，在句中不充当句子成份，if/whether可互换。但if常用于口语中，whether比较正式2.在句子前加上从属连词whether,if该一般疑问句要变为陈述句形式。只能用whether不能用if的情况1.在介词后面：I’mthinkingofwhetherweshouldgofishing.Wedidn’tthinkaboutwhetheritwouldrainthenextday.2.在动词不定式前：Theyaskedmewhethertositatthefront.3.当与ornot连用，或提出两种选择时:Idon’tknowwhetherhe’sfreeornot.MaryaskedwhetherIwasdoingmyhomeworkornot.Tellmewhetheryou’dliketogoshoppingortidytheroom.4.宾语从句提前时：Whetherthisistrueornot,Ican’tsay.5.在动词discuss后的宾语从句中:Wediscussedwhetherwewouldhaveasportsmeetingnextweek.6.引导表语从句或位于句首的主语从句用whether：Whetherheisrightorwrongisaquestion.Thequestionwaswhetherhewenttherelastnight.用if不用whether的情况:1.引导否定概念的宾语从句时：HeaskedmeifIhadn’tfinishmyhomework.2.引导条件状语从句，if意为“如果”时:We’llgohikingifitdoesn’traintomorrow.把下列各句变为宾语从句1.IsJimathome?(Iwonder…)Iwonderwhether/ifJimisathome.2.IsJuneagoodtimetovisitHongKong?(Hewonders…)Hewonderswhether/ifJuneisagoodtimetovisitHongKong.把下列各句变为宾语从句3.Doeshelikesports?(Doyouknow…)Doyouknowwhetherhelikessports?4.Willtheyplaybasketballafterschool?(Heasks…)Heaskswhethertheywillplaybasketballafterschool.Ⅱ.if和whether引导宾语从句时，要注意宾语从句三要素，即连词、语序和时态。由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。如：DoesMrZhaoliveinRoom208?Couldyoutellme?→Couldyoutellmeif/whetherMrZhaolivesinRoom208?1.Idon'tknowifMr.Wang____onafieldtrip.Ifhe___onafieldtriptomorrow,pleasecallme.A.goes;willgoB.willgo;goesC.willgo;willgoD.goes;goes2.SheaskedmeifIknew______.A.whosepenwasitB.whosepenitwasC.whosepenitisD.whosepenisitBB3.Theywonderediftheteacher______usEnglishthenextterm.A.wouldteachB.hadtaughtC.willteachD.taughtAChoosetherightanswers.5.Ihaven’tdecide____I’llgooutorstayathome.A.ifB.whenC.whyD.whether6.Iwanttoknow______helovesyou.A.thatB.whatC.ifD.whoDC4.Theboyasked______anynoisefromoutside.A.whetherhadIheardB.whetherIhadheardC.whetherhaveIheardD.whetherIhaveheardBAC7.Iwondered____ourteacherwasgoingtoattendourparty.A.whetherB.whyC.whereD.that8.I’dliketoknow_____ornot.A.whetherwillhecomeB.whetherhashecomeC.whetherhewillcomeD.ifhewillcome改为含宾语从句的复合句1.Willthetrainarriveontime?Iwanttoknow.Iwanttoknow_______thetrain______ontime.2.DidPetercomehereyesterday?LiLeiwantstoknow.LiLeiwantstoknow_________Peter_________hereyesterday.willarriveif/whethercameif/whetherCompletethesentences.1.我们不知道我们能否在火星上种植植物。Wearewondering__________________________________onMars.2.你能告诉我是不是有许多人打算搬到火星上去吗？Couldyoutellme_______________________________________toMars?whether/ifwecanif/whethermanypeoplearegoingtomovegrowplants3.我不知道他在家洗不洗衣服。Idon'tknow_________________________anywashingathome.4.我担心是否伤害了她的感情。Iamworriedabout___________________________.whetherornothedoeswhetherIhurtherfeelings1.UncleWangcameuptosee__________therewasanythingwrongwiththemachine.2.Theshopkeeperaskedmyfather________ornothewantedtochooseabigChristmastree.if/whetherwhether3.Idon’tknow__________togoorstay.4.________thatistrue,whatshouldwedo?whetherIf5.________theywilleverbecomefutureOlympicchampio
