宾语从句专练宾语从句(TheObjectClause)在复合句中作主句的宾语。宾语从句通常由下面一些词引导。1、由that引导（that在口语或非正式文体中常省略）。2、由what,when,where,which,who,how,why等连接代词或连接副词引导。3、由连词whether或if引导（口语中常用if）。应注意的几个问题：1、宾语从句可放在形容词后。常用形式是“be+形容词+宾语从句”e.g.Iamgladyoulikeit.2、宾语从句与主句时态的一致。1）主句是现在（或将来）时态时，宾语从句可根据实际需要用不同的时态。如：HesaysMaryisplayingwiththecat.HesaysMaryoftenplayswiththecat.HesaysMarywillplaywiththecat.Ithinkheleftyesterdaymorning.2)主句时态是一般过去时，从句要用过去时态的某种形式。HesaidMarywasplayingwiththecat.Hesaidhehopedtobebacksoon..3)当从句所表示的是客观事实或客观真理时，该从句都用一般现在时，不用过去时。如：Hesaidlighttravelsmuchfasterthansound.3、宾语从句中的否定转移。如果主句谓语动词是think,believesuppose等，而从句的意思是否定的，这时主句的谓语动词用否定式，从句用肯定式。如：Idon’tthinkyouareright.我认为你不对。4、将普通的特殊疑问句变成宾语从句时，从句的语序要由疑问句变成陈述句的语序。Whenwillthemeetingbegin?-------Iwanttoknowwhenthemeetingwillbegin.5、将普通的一般疑问句变成宾语从句时，则用if/whether连接，同时变成陈述句语序。AreyouanEnglishteacher?-------HeaskedifIwasanEnglishteacher.在下列情况下只能用whether1）介词后的宾语从句I’mthinkingaboutwhetherweshouldgofishing.2）宾语从句提前时Whetherthisistrueornot,Ican’tsay.3）直接与ornot连用时Idon’tknowwhetherornothewasready.4）在带to的动词不定式前Shehasn’tdecidedwhethertogoornot.if也可引导条件状语从句，表示“如果”（主将从现，主过从过）。比较：Idon’tknowifhewillcome.Ifhecomes,Iwilltellyou.6、在变宾语从句时，要注意以下几点。1）连接词2）人称3）语序4）时态5）标点练习1．用所给动词的适当形式填空。1）Iknowthattheyoungman______________(come)tothevillageeverySaturday.2).Wehavelearntthattheearth________________(go)aroundthesun..3)Hewasafraidthathe______________________(forget)hisChinese.4)Iamsurethatshe________________(like)thisbook.5)Hetoldmethathe________________(tell)astorywhenIcamein.6)Couldyoutellmewhenyou_________________(leave)England,lastsummerorlastautumn?7)Sheaskedmeifshe_____________(can,borrow)thesciencebook.8)Ican’trememberwhenhe_____________________(come)lastnight.9)Hesaidhe_______________(fly)toShanghai.10)Sheishappythatshe____________________(find)thelostpurse.11)Ihearthathe__________________(enjoy)playingfootballverymuch.12)Hastheteacherdecidedwho______________(take)partinthesportsmeeting?2.用适当的连接词填空。1)Themotherlikessaying__________________shehasagooddaughter.2)Theytoldme__________________theycouldfinishtheworkbeforeteno’clock.3)Theboywantedtoknow_______________theycouldgoboating.4)MrGreenasked______________wouldgivethemessagetoMissWang.5)Dadwantedtoknow______________thetennismatchwouldbe.6)Shehasn’tdecided______________languagesheisgoingtochoose.7)It’swell-known_________________LuXunwasagreatwriter.8)Doyouknow_____________DoctorKinglive?9)LucywantstoaskLiLei_______hegoestoschoolbybuseveryday.10)Hedoesn’tknow___________shewillgototheUSAtomorrow.11)Ihope____________everybodyatschoolareallwell.12)Lilyasked______________therewereanycheaperones.13)Ididn’tknow_______________thebookswere.14)Doyouknow_______________timeIgetupeveryday.15)Couldyoutellme_____________gradeyouarein?16)Theboydidn’tknow_______________washisnewEnglishteacher.17)Theteacherasked_____________Li...
