1、宾语从句在句子中起宾语作用的从句叫做宾语从句。一.宾语从句根据引导词的不同可分为三种类型：1.由that引导的宾语从句。如：Weknew（that）weshouldlearnfromeachother.2.由if/whether引导的宾语从句。如：Pleasetellmeif/whetheryouhavebeentoAmerica.3.由who，where，how等连接代词或连接副词引导的宾语从句。如：CanyoutellmehowIcangettothenearestpostoffice？二.语序①陈述句变为宾语

2、从句，语序不变，即仍用陈述语序。如：Heisanhonestboy.Theteachersaid.→Theteachersaid（that）hewasanhonestboy.②一般疑问句和特殊疑问句变为宾语从句，语序变为陈述语序。如：Doesheworkhard？Iwonder.→Iwonderif/whetherheworkshard.Whendidheleave？Idon’tknow.→Idon’tknowwhenheleft.三.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。如：Ihavehear

3、d（that）hewillcomebacknextweek.②如果主句是过去的某种时态，那么从句的时态一定要用过去的某种时态。如：Hesaid（that）therewerenoclassesyesterday.注意：如果宾语从句表述的是客观真理、自然现象等时，不管主句是什么时态，从句都要用一般现在时。如：Hesaidthatlighttravelsmuchfasterthansound.将下列疑问句变为宾语从句1.“MayIuseyourknife？”Heaskedme.Heaskedmeifhemightusem
