什么是宾语？Iknowhim.2.Iknowwhoheis.宾语从句三要素一、连接词（引导词）1.当宾语从句是陈述句时（包括肯定句和否定句），连词由that引导，因为that在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略宾语从句中的连接词that在以下三种情况下不能省略：（1）当that从句与另一名词性从句并列作宾语时，第二个that不能省；（2）当that作介词宾语时，that不可省掉。（3）用it做形式宾语的宾语从句Everyoneknewwhathappenedandthatshewasworried.Thereasonliesinthatsheworksharderthantheothersdo.IthinkitnecessarythatyoushouldreadEnglishaloud.2.当宾语从句是一般疑问句时，由连词whether或if引导，“是否”，不能省略a.当有ornot时就用whether,不用if.Idon’tknowwhetherornotIwillstay.b.介词后面的宾语从句不能用if.IworryaboutwhetherIhurtherfeeling.Practicetime3.当宾语从句是特殊疑问句时，由疑问词（what,who,whom,which；whose；when,where,how,why等）引导，因为疑问词在从句中担任一定的句子成分，具有一定的意义，所以不可以省略二、时态1.如果主句是现在的时态，从句的时态可根据实际情况而定，（包括一般现在时，一般过去时，一般将来时，现在完成时等）2.如果主句是过去的时态，那么从句的时态一定要用相对应的过去的某种时态（包括一般过去时，过去进行时，过去将来时，过去完成时）3.当从句是客观真理，定义，公理，定理时用一般现在时。Theteachertoldmeshe____(be)bornin1960.Iheardthatshe____(go)toParislastnight.1.Mikeinsistedthatwe_________________(be)lateforschool.2.Thedoctororderedthatshe_____________(stay)inbedforafewdays.注意：在下列动词接that从句中用“should+动原”三、语序宾语从句的语序用陈述语序：主句＋连接词+主语+谓语+其他成分1.Whenwillhegotothelibrary?Hisbrotheraskswhenhewillgotothelibrary.Hisbrotheraskswhenwillhegotothelibrary.What’swrong?What’sthematter?What’shappening?Whathappened?否定的转移注意：这类句子后若带有附加疑问句，应采用肯定形式来后问，后问部分应于从句主语一致。Idon’tbelievesheknowit,doesshe?1.Wewonderhowweshalldonext.2.Couldyoutellmewherearetheyhavingapicnic?3.IamsorrythatIdon’tknowyouwanttotakepartinthecompetition.4.Ididn’tknowthatyouwillcome.5.Hesaidthatheiswritingastory.6.Couldyoutellmewhenwillhearrive?7.YoucanbegintoseewhydoesEnglishhavesuchstrangerules.Exercise:multical-choice1.Idon’tknow____wecanliveontheislandwithoutfood.A.whereBwhatChowDthat2.Couldyoutellme___________________?Awhereisthepark?Bwho’sonduty?Cwhosebookisthis?Dwhataretheydoing?3Theteachertoldusthattheearth_____aroundthesun.AmovedBmovesCmoveDmoving4.Ididn’tknowthatMr.Smith______yet.hasreturnedBhasreturnedChadreturnedDreturned5.Wedon'tknow______theydidit.Wedon’tknow______theydid.A.howB.whoC.whatD.which一、表语从句定义：LinkingVerbs(连系动词)除动词be以外，还有
