外研社八年级下册宾语从句讲解及专项练习

一、宾语:是表示及物动词的动作对象，放在及物动词后面。例如：Sheplaysthepiano.Heoftenhelpsme.IlikewatchingTV.二、宾语从句：从句在句中起宾语的作用，就叫宾语从句。三、宾语从句的时态：当主句为一般现在时，从句可用任何一种时态；Shesaysthatshewillcome.她说她会来。当主句为一般过去时，从句用过去相应的时态。Shesaidthatshewantedtohaveatry.她说过她想试一试。当从句客观真理时，从句用一般现在时。Ourteachersaidtheearthgoesaroundthesun.我们的老师说过地球围绕着太阳转。1、陈述句变宾语从句：用that引导，通常可以省略。翻译：我认为你是对的。_____________________________________________她说她是个学生。_____________________________________________2、一般疑问句变宾语从句（…...吗？）当一般疑问句变成宾语从句时，我们需要用if或whether来引导。例如：Isittrue？这是真的吗？→_____________________________________________我想知道是否是真的。Areyouastudent？你是一个学生吗？→_____________________________________________他问我是不是学生。注意：一般疑问句中的疑问语序要变成_________语序。3、特殊疑问句变宾语从句用特殊疑问句本身的疑问词引导，特殊疑问句中的疑问语序要变成陈述语序。如：Doyouknow？WherecanIparkmycar？（两个特殊疑问句）将两个句子合成宾语从句：_____________________________________________注意：特殊疑问句中的疑问语序也要变成_________语序。专项练习一、根据宾语从句的时态，用所给动词的正确形式填空.1.Wearesurethathe_________(go)toschooltomorrow.2.Doyouknowwho________(be)thefirstmantowalkonthemoon3.Couldyoutellmewherethepostoffice______(is)4.Ourfathersaidthathe____________(will)buyanewcomputer.5.Ihearthathe____________(swim)intheseayesterday.6.Thelittleboytellsuswherehisfather____________(work).7.Hesaidthathe_________(finish)hisworkalready.8.Theythoughttheycould________(hike)tothetopofthemountain.9.Hewasgladthatsomanypeople_________(help)him.10.Shedoesn'tknowwhether_____________(go)orwait.二、请将以下句子转换成宾语从句。（考虑三方面：引导词、时态、语序）1.Hewillcomebackinaweek.→Ithink_________he____________________________backinaweek.2.Whoishelookingfor?→Doyouknow________________________________lookingfor?3.Whyistheplanelate?→Ididn’tknow_________theplane____________________________.4.Hehasalreadycomeback.→Hetoldme_________he______________alreadycomeback.5.HowcanIgettotheSummerPalace?→Couldyoutellme________________________________gettotheSummerPalace?6.Whydidn’thecomeyesterday?→Canyoutellme________________________________comeyesterday?7.Whataretheydoing?→Tomdidn’ttellme______________they______________doing.8.WhenwillwehaveanEnglishtest?→Theteacherdidn’ttellus_____________________________haveanEnglishtest.9.Wherewillthemeetingbe?→Iaskedhim_________themeeting______________be.10.Whosewatchisthis?→Doesanybodyknow________________________________________________________?11.WasthewatchmadeinShanghai？→Idon'tknow____________thewatch____________madeinShanghai.三、将下面的句子连接成为含有宾语从句的复合句.1.TheseflowersarefromGuangdong.Hesaid.→Hesaid_______theseflowers____________fromGuangdong.2.Lighttravelsfasterthansound.Myteachertoldme.→Myteachertoldme__________light____________fasterthansound.3.Therewillbeameetinginfivedays.Jackdidn'tknow.→Jackdidn'tknow_______there______________ameetinginfivedays.4.CantheyspeakFrench？Iwanttoknow.→Iwanttoknow__________________________________________French.5.Arethechildrenplayinggames？Tellme.→Tellme___________thechildren______________________games.6.Wheredidsheparkhercar？Doyouknow？→Doyouknow_____________________________hercar？7.Whatdoesheoftentalkabout？Thegirlwondered.→Thegirlwondered____________________often____________about.8.WhoknockedatthedoorsoloudlyIdon'tknow.→Idon'tknow_____________________atthedoorsoloudly.9.Doeshestillliveinthatstreet？Idon'tknow.→Idon'tknow___________hestill____________inthatstreet.10.What'syourname？Iaskedhim.→Iaskedhimwhat______________________________.11.Whendoesthetrainarrive？Pleasetellme.→Pleasetellme_________________________________________________.12.Dotheywantfriedchicken？Heaskedtheboys.→Heaskedtheboys____________they___________friedchicken.陈述句变宾语从句：1.“I’mmakingamodeltrain.”Hesaid._____________________________________________________2.“Theticketsareinmypocket.”Themansays._____________________________________________________3.“Iwillcomeback.”Tomsays._____________________________________________________一般疑问句变宾语从句：Willhecomeheretonight?I’mnotsure._____________________________________________________Didthemanpayforthemeal?Thebossaskedthewaiter._____________________________________________________Heasked.Isitgoingtoraintomorrow?_____________________________________________________特殊疑问句变宾语从句：Whoseisthatcar?Thepolicemanasked._____________________________________________________Howistheweatherlike?Shewantedtoknow._____________________________________________________Canyoutellme?Wheredidtheyspendtheirholiday_____________________________________________________二、选择题。（）1Thegirlsaskedifthey_____somefoodanddrinkwiththem.A.tookB.takeC.takesD.willtake（）2Catherinesaidthatshe____toGuangzhou.A.hasnevergoneB.hadnevergoneC.hasneverbeenD.hadneverbeen（）3Thestudentswanttoknowwhetherthey_____dictionarytoday.A.hadB.hasC.willhaveD.are（）4SheaskedLindaif_____goandgetsome.A.couldsheB.shecouldC.shecanD.shemay（）5Lindasaidthemoon____roundtheearth.A.traveledB.hastraveledC.travelsD.hadtraveled（）6.Idon’tknow_____.A.whatdoeshelikebestB.whathelikebestC.whathedoeslikebestD.whathelikesbest.（）7.Canyoutellme_____?A.whereshelivesB.wheredoessheliveC.sheliveswhereD.whereshelive（）8.Heaskedme_________.A.whattimeisitB.whattimeitisC.whattimewasitD.whattimeitwas（）9.Doyouknow___?A.howmuchdiditcos
