賓語從句是主從復(fù)合句的一種。主從復(fù)合句是由一個(gè)主句和一個(gè)或一個(gè)以上的從句構(gòu)成的。主句是復(fù)合句的主體，從句僅僅是主句的一個(gè)成分，它從屬于主句，不能獨(dú)立。從句在全句中充當(dāng)什么成分，就叫什么從句。賓語從句當(dāng)中的從句在全句中作賓語。一．賓語從句的連接詞1.由從屬連詞that引導(dǎo)的賓語從句：that在句中無詞匯意義，在從句中不能充當(dāng)成分，在口語中往往省略。例如：Hesaid(that)hewantedtostayathome.Shedoesn'tknow(that)sheisseriouslyill.Iamsure(that)hewillsucceed.2.if/whether引導(dǎo)賓語從句。意為是否，僅起連接作用，if/whether在從句中不作任何成分。Couldyoutellmeif/whetherit'spolitetospeakloudlyatthetable?Idon'tknowif/whetheryouareright.Idon'tknowwhetheryouarerightornot.3.由連接代詞Who,whom,whose,which，what和連接副詞where,how,why,when引導(dǎo)的賓語從句，這些連接代詞和連接副詞在賓語從句中充當(dāng)某個(gè)成分。例如：Doyouknowwho(whom)theyarewaitingfor?Heaskedwhosehandwritingwasthebest.CanyoutellmewheretheNo.3busstopis?Idon'tknowwhythetrainislate.考點(diǎn)歸納(1)——賓語從句的連接詞1.that只起連接作用，在句子中不做句子成分，在口語中常被省略2.If和whether起連接作用，不做句子成分。（注意：與不定式連用；做介詞的賓語；與ornot連用——用whether。)3.疑問詞who、what、when、where、whom、whose、why、how、which在句子中既起連接作用，又做句子成分。二.賓語從句的語序賓語從句的語序應(yīng)為陳述句的語序。例如：Ihear(that)physics

isn'teasy.Ithink(that)you

willlikethisschoolsoon.CanyoutellmehowIcangettothezoo?Pleasetellmewhenwe'llhavethemeeting.考點(diǎn)歸納(2)——賓語從句的語序賓語從句的語序是陳述句（即主語+謂語）的順序。選一選：(1)Canyoutellme____?(A.whomdowehavetoseeB.whomwehavetosee)(2)Theteacheraskedthestudents____.(A.whattheyweredoingB.whatweretheydoing)(3)Shewantstoknow____.(A.wheredoesheliveB.Wherehelives)(4)Herfatherasked_____.(A.whothetallestisB.whoisthetallest)(5)Doyouknow____?(A.whatisonthedeskB.whatonthedeskis)參考答案：BABBA三.賓語從句的時(shí)態(tài)1.如果主句的時(shí)態(tài)是一般現(xiàn)在時(shí)，賓語從句該用什么時(shí)態(tài)就用什么時(shí)態(tài)。即，從句可用所需的任何時(shí)態(tài)。如：Idon’tthink(that)youareright.Pleasetelluswhereheis.CanyoutellmehowIcangettotherailwaystation?HesaysMaryisplayingwiththecat.HesaysMaryoftenplayswiththecat.HesaysMarywillplaywiththecat.Ithinkheleftyesterdaymorning.2.如果主句的時(shí)態(tài)是一般過去時(shí)，賓語從句只能用相應(yīng)的過去時(shí)態(tài)（一般過去時(shí)，過去進(jìn)行時(shí)，過去將來時(shí)，過去完成時(shí)）。例如：Heaskedwhattimeitwas.Hetoldmethathewaspreparingforthesportsmeet.HeaskedifyouhadwrittentoPeter.HesaidthathewouldgobacktotheU.S.soon.Hesaid,“Maryisplayingwiththecat.”→HesaidMarywasplayingwiththecat.Hesaid,“hewillgobacktoChinasoon.”→HesaidhewouldgobacktoChinasoon3.如果賓語從句所陳述的是客觀真理，其時(shí)態(tài)常用一般現(xiàn)在時(shí)，不受主句時(shí)態(tài)的限制。例如：OurteachersaidthatJanuaryisthefirstmonthoftheyear.Scientistshaveprovedthattheearthturnsaroundthesun.Theteachersaid,“themoonmovesaroundthesun.”→Theteachersaidthatthemoonmovesaroundthesun.Hesaid,“l(fā)ighttravelsmuchfasterthansound.”→Hesaidlighttravelsmuchfasterthansound.4、當(dāng)主句為Couldyou(please)tellus-----?時(shí)，只表示語氣，而不表示過去時(shí)態(tài)?？键c(diǎn)歸納(3)——賓語從句的時(shí)態(tài)1、當(dāng)主句動(dòng)詞為一般現(xiàn)在時(shí)，從句可用所需的任何時(shí)態(tài)。2.當(dāng)主句動(dòng)詞為一般過去時(shí)，賓語從句只能用相應(yīng)的過去時(shí)態(tài)（一般過去時(shí)、過去進(jìn)行時(shí)、過去將來時(shí)、過去完成時(shí)）。3.當(dāng)賓語從句為客觀真理時(shí)，用一般現(xiàn)在時(shí)態(tài)，不受主句時(shí)態(tài)的限制。4.當(dāng)主句為C
