宾语从句的引导词

宾语从句的引导词一、宾语从句：置于动词、介词等词性后面，在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语从句过"三关"：时态，语序，连词。宾语从句的语序必须是陈述语序，谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句，有些形容词(afraid，sure，glad等)之后也可以带宾语从句。二、宾语从句中引导词的用法在复合句中作主句的宾语，引导词有：连词：that(that常可省略),whether,if代词：who,whose,what,which副词：when,where,how,why等。(一)that引导的宾语从句(在非正式场合that可以省略)可跟that从句做宾语的动词有：say,think,insist,wish,hope,demand,imagine,wonder,know,suppose,see,believe,agree,admit,deny,expect,explain,order,command,feel,dream,suggest,hear,mean,notice,prefer,request,require,propose,declare,report等。例句：Theboybelievesthathewilltravelthroughspacetootherplanets.（注意事项：当主句谓语动词是think,believe,suppose,expect等词，而宾语从句的意思是否定时，常把否定转移至主句表示。）例句：Idon’tthinkitisrightforhimtotreatyoulikethat.在以下情况中that不能省略1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。例句：Hesaid(that)youweretooyoungtounderstandthematterandthathewasaskednottotellyou.2、当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。例句：JustthenInoticed,forthefirsttime,thatourmasterwaswearinghisfinegreencoatandhisblacksilkcap.3、当that从句是双宾语中的直接宾语时，that不可省。例句：Ican’ttellhimthathismotherdied.（注意事项：许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。）例句：Ifinditnecessarythatweshoulddothehomeworkontime.(二)由whether,if引导的宾语从句由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。例句：Iwonderwhether(if)theywillcometoourparty.只能用whether，不能用if引导的宾语从句1、在带to的不定式前例句：Wedecidedwhethertowalkthere.2、在介词的后面例句：I’mthinkingofwhetherweshouldgotoseethefilm.3、在动词后面的宾语从句时例句：Wediscussedwhetherwehadasportsmeetingnextweek4、直接与ornot连用时例句：Ican’tsaywhetherornotthetcancomeontime.只能用if不能用whether引导的宾语从句1、if引导条件状语从句，意为“如果”例句：Thestudentswillgoonapicnicifitissunny.2、if引导否定概念的宾语从句时例句：HeaskedifIdidn’tcometoschoolyesterday.3、引导状语从句evenif(即使)和asif(好象)时例句：Hetalksasifhehasknownallaboutit.C.whatthematterisD.what'sthematter（）10.Heaskedhisfather_______.A.whereithappensB.wheredidithappenC.howithappenedD.howdidithappen二、将下面的句子连接成为含有宾语从句的复合句。1.“TheseflowersarefromGuangdong.”Tomsaid.Tomsaid_______theseflowers_______fromGuangdong.2.“Lighttravelsfasterthansound.”MyteachertoldMark.MyteachertoldMark_____light_______fasterthansound.3.“Therewillbeameetinginfivedays.”Jackdidn’tknow.Jackdidn’tknow_____there_________ameetinginfivedays.4.“CantheyspeakFrench?”Iwanttoknow.Iwanttoknow___________________________French.5.“Arethechildrenplayinggames?”Tellme.Tellme______thechildren____________games.6.“Haveyoufinishedyourhomeworkyet?”Mr.GuoaskedSunJia.Mr.GuoaskedSunJia____________________homeworkyet.7.Howmanypeoplecanyouseeinthepicture?Whoknows?Whoknows_______________________________inthepicture?8.Wheredidsheparkhercar?Doyouknow?Doyouknow______________hercar?9.“Whatdoesheoftentalkabout?”Nancywondered.Nancywondered__________often________about.10.Whoknockedatthedoorsoloudly?Idon’tknow.Idon’tknow___________atthedoorsoloudly.三、用合适的连接词填空。1.Jimtoldme____hedidn'tgofishingyesterdayafternoon.（how,why）2.Doyouknow______elseisgoingtobeondutytoday?（who,whom）3.Shesaid_____itwouldn'tmattermuch.（that,if）4.Healwaysthinks______hecandobetter.（how,who）5.Ireallydon'tknow________thebridgewillbefinished.（howlong,howsoon）6.Theydon'tknow_______togoorwait.（if,whether）7.Wearetalkingabout______we’llgobacktomorrow.（whether,if）8.Iwasreallysurprisedat______Isaw.（where,what）9.Idon'tknow____somanypeoplearelookingathim.（how,why）10.Doyouknow______youarestudyingfor?（why,what）四、句型转换。1.“Doyouwanttotryit?”Tom'smotheraskedhim.（同义句）→Tom'smotheraskedhim____________________totryit.2.Ithinkthisisagoodidea.（改为否定句）→I_______________this________agoodidea.3.Lucyhasn'tdecidedwhichtrouserstobuy.（改为复合句）→Lucyhasn'tdecided________________________________buy.4.Idon'tknowhowIcangettothehospital.（改为简单句）→Idon'tknow________________________tothehospital.5.Idon’tsupposetheywillcome,_____________?（改为反意疑问句）五、用所给动词的正确形式填空。1.Wearesurethathe________（go）toschooltomorrow.2.Doyouknowwho______（be）thefirstmantowalkonthemoon?3.Couldyoutellmewherethepostoffice______（is）?4.Ourfathersaidthathe_______（will）buyanewcomputer.5.Ihearthathe_______（swim）intheseayesterday.6.Thelittleboytellsuswh
