Unit3 period3 grammar主语从句和表语从句

宾语从句宾语从句是主从复合句的一种。主从复合句是由一个主句和一个或一个以上的从句构成的。主句是复合句的主体，从句仅仅是主句的一个成分，它从属于主句，不能独立。从句在全句中充当什么成分，就叫什么从句。宾语从句当中的从句在全句中作宾语。引导宾语从句的词有：连词that(在口语中that常可省略）if,whetherHeknowsthatJimwillworkhard.连接代词who,whom,which等Doyouknowwho(whom)theyarewaitingfor?连接副词when,where,how,whyCouldyoutellmehowwecangettothestation?whether/if•whether和if都有“是否”的意思，一般情况下两者可以换用，但在介词之后，不定式之前，与ornot连用，在句首或在引导表语从句，同位语从句时，只能用whetherIwanttoknowif/whetherthenewsistrue.Hedoesn'tknowwhethertostayornot?动词doubt用在疑问句或否定句时，其后宾语从句常用that作连接词；用在肯定句时，连接词用whether或if皆可，而不用that。Doyoudoubtthathewillwin?Idon'tdoubtthatyourpropositioniswrong.Hedoubtswhether/ifIknowit.1Doyouknow______?A.whattimewilltheplanetakeoffB.whattimewouldtheplanetakeoffC.whattimetheplanewilltakeoffD.theplanewilltakeoffatwhattime解析:宾语从句要用陈述句的语序，故选C。2Themanagercameuptosee_______.A.whatwasthematterB.whatthematterwasC.whatthematterisD.what'sthematter解析:本题主句用了过去式，故从句要用过去范畴的时态，所以排除C和D，又因为what在从句中充当主语，所以语序不变，故选A。3NobodybutJimandhisuncle______.A.knowwhoisheB.knowwhoheisC.knowswhoisheD.knowswhoheis解析:Nobodybut…句式中的谓语动词为单数,即取决于but前面部分.要用knows,排除A、B，然后检查陈述句语序，故选D。1.Choosingtherightdictionarydependson______youwanttouseitfor.(2007江苏卷)A.whatB.whyC.howD.whether2.CouldIspeakto_________isinchargeofInternationalSales,please?(2007山东卷)A.anyoneB.someoneC.whoeverD.nomatterwho3.–Ithinkit’sgoingtobeabigproblem.-Yes,itcouldbe.-Iwonder_____wecandoaboutit.（2002春）A.ifB.howC.whatD.that4.Theseasideheredrawsalotoftouristseverysummer.Warmsunshineandsoftsandsmake________itis.(2007天津卷)A.whatB.whichC.howD.where在下列各空白处填上适当的连接词，使句意通顺1.Theydon'tknow_____wearegoinghiking.2.Shewantedtoknow__________hercoatwouldbereadythenextday.3.Iwasreallysurprisedat_____Isaw.4.Idon'tunderstand_____somanypeoplearecrowdingroundhim.5.Doyouknow______skirtitis?whenIf/whetherwhatwhywhose1.Ireallyhavenoidea(我该选择什么课题)2Ourteachertoldus_____________.(光速比声速快多了)3.Ididn‘ttellhim____________(我参加了什么项目)4.I___________________(认为他没有时间和你打高尔夫球)5.Theyarediscussing__________(这答案是否正确)翻译下列画横线句子1.IreallyhavenoideawhatsubjectIshouldchoose.(我该选择什么课题)2.Ourteachertoldusthatlighttravelsmuchfasterthansound.(光速比声速快多了)3.Ididn'ttellhimwhichsportIwasin.(我参加了什么项目)4.Idon'tthinkhehastimetoplaygolfwithyou.(认为他没有时间和你打高尔夫球)5.Theyarediscussingiftheanswerisright.(这答案是否正确)表语从句定义：一个从句在复合句中作主句的表语，这个从句就叫作表语从句。1.Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.2.Thequestionremainswhetherwecanwinthepeople.3.That’sjustwhatIwant.1.从属连词that（一般不省略为好），whether（不用if），asif（though）等引导的表语从句。Thereason（why）shehasn'tcomeisthat（此处不可用because）shehastosendhermothertoahospital.她没来是因为她必须送母亲去医院。2.连接代词what，which，who,whom，whose等引导的表语从句。ThisiswhatIwanttosay.这就是我想说的。3.连接副词when，where，how，why等引导的表语从句。Thisishowweovercomethedifficulties.这就是我们克服困难的方法。1Mariahastobebaby-sit.That’s______shecan’tcomeoutwithus.A.whyB.howC.whenD.what2---Iwenttoseeyouatabouttenthismorning,butyouwerenotintheoffice.---Oh,thatwasprobably________Iwastalkingwiththeheadmaster.A.whenB.whyC.whatD.that3.Allfinished,wesatdowntoenjoy______wethoughtthemostdeliciousdinner.A.thatB.whichC.whatD.it4.Shelooked_____sheweretenyearsyounger.A.thatB.asthoughC.asD.like5.ThereasonIhavetogois_____ifIdon't.A.thatshewillbedisappointedB.becauseshewillbedisappointedC.onaccountofherbeingdisappointedD.thatshewillbedisappointing6.Itwas_____heworkedhardthathesucceeded.A.sinceB.becauseC.asD.for7.Whatthedoctorsreallydoubtis____mymotherwillrecoverfromtheseriousdiseasesoon．AwhenBhowCwhetherDwhy8.—IdrovetoZhuhaifortheairshowlastweek．—Isthat____youhadafewdaysoff？AwhyBwhenCwhatDwhere1.Seetheflagsontopofthebuilding?Thatwas______wedidthismorning.（2006全国Ⅰ）A.whenB.whichC.whereD.what2.—Areyoustillthinkingaboutyesterday’sgame?(2003北京春)—Oh,that’s_____.A.whatmakesmefeelexcitedB.whateverIfeelexcitedaboutC.howIfeelaboutitD.whenIfeelexcited3.Greatchangeshavetakenplaceinthatschool.Itisnolonger______itwas20yearsago,_____itwassopoorlyequipped.（2005安徽）A.what;whenB.that;whichC.what;whichD.which;that4.Theplace______thebridgeissupposedtobebuiltshouldbe______thecross-rivertrafficistheheaviest.（2005江苏）A.which;whereB.atwhich;whichC.atwhich;whereD.which;inwhich
