《宾语从句讲解》PPT课件.ppt

一。分类。1.当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。如:eg.1.1Shesaidthatshewouldleavethemessageontheheadmastersdesk.1.2Hesaidthathecouldfinishhisworkbeforesupper.2.当由一般疑问句充当宾语从句时,用ifwhether引导,意为“是否”。Eg.2.1Alicewantedtoknowif/whetherhergrandmotherlikedthebag.(Doesgrandmotherlikethebag?)2.2Idontknowwhetherhellcomethedayaftertomorrow.(willhecomethedayaftertomorrow?),3.如果宾语从句原来是特殊疑问句,只需用原来的疑问词引导.Eg.Couldyoutellmewherewewillhavethemeetingthisafternoon?Idontknowwhoboughtthepresentforme.IsitJack?,二.答题要点.1.句式：主句+连词+从句2.分类：2-1.主句+that+陈述句从句2-2.主句+if/whether/原有特殊疑问词+疑问句从句3.注意：3-1.疑问句语序改为陈述句语序3-2.时态一致（主句为现在时/主句为过去时）,三.宾语从句的其他注意要点.If/whether引导的是宾语从句还是状语从句：是否（宾语从句）/如果（状语从句）Eg.Iwonderifyouhavetimetoplaywithme.Ifyouhavetime,pleasewashthedishes.2宾语从句的反意疑问句：当主句的主语为第一人称时，陈述部分含有宾语从句的复合句时，附加反意问句部分的人称和时态随从句变化；但是当主句的主语为第二/三人称时，陈述部分附加反意问句部分要与主句中的主语/谓语动词保持对应关系，还要注意否定转移。Eg.Imsurehehasfinishedhiswork,hasnthe?Wesupposeyouhavefinishedtheproject,haventyou?,Ithinkhecancomehereontime,doesnthe?Idontthinkhecancomehereontime,doesheYoursistersupposessheneedsnohelp,doesntshe?Theydontbelieveshesanengineer,dothey?Shedoesntexpectthatwearecomingsosoon,doesshe?Youthoughttheycouldhavecompletedtheproject,didntyou?,3.宾语从句的简化：3-1主句谓语动词为：hope/agree/decide时，其后带有that宾语从句，而且主句的主语和从句的主语相同时，从句可简化为不定式结构。Eg.HehopethathecouldpasstheEnglishexam.(简单句)HehopetopasstheEnglishexam.3-2.主句谓语动词为:see/watch/hear/find宾语从句常常简化为“宾语+宾语补足语”结构。其中宾语为that从句的主语转化而来；补足语为省to的不定式或V.-ing形式。Eg.Jackheardthatthegirlsangasongjustnow.Jackheardthegirlsingasongjustnow.,3.宾语从句还可以转化
