NounClause名词性从句NounClause名词性从句、本讲内容:学习名词性从句。、学习要求:()掌握名词性从句的种类。()引导名词性从句的连接词。()初步学会运用名词性从句。名词性从句、学习指导:()本讲重点:名词性从句的种类。()本讲难点:名词性从句的语序。、典型例题解析:名词性从句包括主语从句、表语从句、宾语从句和同位语从句。它的功能相当于名词引导名词性从句的引导词归纳起来可分为以下三类。、主词从句()Thathewillcomeiscertain()Whethersheiscomingornotdoesn’tmattertoomuch()Whatsurprisedmemostwastoseesomeofthevillagepeopleseatedonthebenchesattheendoftheroom()Whichteamwillwinthematchisamatterofpublicconcern()Whereshehasgoneisnotknownyet当主语从句较长时多放在句子后部用it作形式主语。以it作形式主语把主语从句后置的常用句型有:Itbe形容词that从句Itiswascertainthat–clauseclearimportantnecessaryprobablepossible()Itiscertainthatshewilldowellinherexam()Itisprobablethathetoldmeeverything、Itbe名词词组that从句Itiswasapitythat–clauseshameduty()Itisapitythatwecan’tgo()Itisnosurprisethatourteamshouldhavewonthegame、Itbe过去分词that从句Itissaidthat–clausereportedthoughthopedbelievedknown()Itissaidthatheisthebeststudentintheclass()ItisthoughtthatJoedrivesbadly、Itseem,happen,appear等不及物动词that从句。()ItseemsthatAliceisnotcomingtothepartyatall()IthappenedthatIwasoutthatday()ThiswaswhatTomwasreading()ThetruthisthatIhaveneverbeenthere()Itlooksasifitisgoingtorain()Thereasonwhyhewaslatewasthathegotuplate()Thisishowweovercamethedifficulties()Thatiswhyshewasabsentyesterday()ThehouseiswhereLuXunoncelived、表词从句:、宾语从句、用作及物动词的宾语()Theypretendedthattheywerereadingintheroom()Ididn’tknowwhattheyweretalkingabout()Doyouknowwhywinteriscolderthansummer()Hecouldn’ttellwherehishomewas()Johnmadetheboysitstill,promisingthatnothingwouldhurthim引导宾语从句的连词that常可省去特别在口语中是这样。注意:whether和if引导的宾语从句:whether和if引导宾语从句时可以互换使用但下列情况用whether不用if。()在whetherornot结构中不可用if代替whetherIdon’tknowwhetherornothe’llcomeIwonderwhetheritistrueornot()介词后面的宾语从句用whether不用ifEverythingdependsonwhetherthesituationwillimprove(后面要讲到介词后面的宾语从句)()引导主语从句和表语从句用whether不用ifWhetherwe’llgodependsontheweatherThequestioniswhetheritisworthdoing()whether可用在不定式前if则不能Pleasetellmewhethertogoornot、用作介词的宾语从句:IwaspleasedbywhathetoldmeHealwayspaysattentiontowhatevertheteachersaysHetoldofhowhehelpedtheoldwomantofindhermissingson这类形容词常见的有sure,certain,glad,pleased,happy,afraid,surprised,satisfied等。()Iamsureyoulookedbeautifulthatevening()Wewerenotsurprisedthathereturnedthreedayslaterthanexpected、用作某些形容词的宾语从句:()Everyonewasafraidthatsomeonemightfindoutthathecouldseenothing()Motherwasverypleased(that)herdaughterhadpassedtheentranceexams注意:如果宾语从句后边还有宾语补足语则用it作形式宾语而将宾语从句后置。如:()WethoughtitstrangethatXiaoWangdidnotcomeyesterday()Hehasmadeitclearthatanyonewhobreaksthelawistobepunished这种句型的谓语动词有think,make,feel,find,consider、同位语从句同位语从句在句中作某些名词的同位语这些名词常见的有fact,news,hope,truth,idea,suggestion,thought,question,order,problem,belief,doubt,fear等。引导同位语从句的连词通常有that和whether,what,why,how…等。()TheyexpressedthehopethattheywouldcomeovertovisitChinaagain()Weallknowthetruththattheearthgoesroundthesun()Thefactthatshehadnotsaidanythingsurprisedallofus()Theyaskedmethequestionwhethertheworkwasworthdoing()Theyproblemwhetheritisrightorwronghasnotyetbeendecided注意:同位语从句和定语从句的区别是:前者说明名词的内容后者说明名词的性质特征前者所用连词that不是从句的一个成分后者所用关系代词that是从句中的一个成分。试比较:HeputforwardthesuggestionthatthesecondquestionshouldbediscussedfirstThesuggestionthathehadputforwardwasturndown(同位语从句)(定语从句)以上是名词性从句例题解析下面就运用名词性从句时要注意的几个方面作以归纳:()语序在名词性从句中从句一律使用陈述语序。特别要注意由连接代词和连接副词引导的从句(what,who,which,when,where,now,why等),不可用特殊疑问句的影响而用了疑问句语序。如:()Iwonderwhosheis()Thequestioniswhenwe’llcompletetheworks()Whethersheiscomingornotdoesn’tmattertoomuch()时态:学习名词性从句时除了要注意从句的引导词语序等外还要注意从句谓语动词与主句谓语动词的时态一致关系。()在宾语从句中当主句是一般现在时宾语从句可以根据需要用各种时态。如:MarysaysthatTomisn’tlazyTomisdoingwellinhislessonShewillaskTomsomequestionsTommayfallbehindtheothersShemissedusverymuchShewaswritingaletterShewouldvisittheGreatWallShesaidthat如果主句谓语动词是一般过去时则宾语从句须用过去的某种时态。如:如果宾语从句表示的是客观真理其谓语动词则仍用一般现在时。如:()Theteachersaidthatlighttravelsmuchfasterthansound()Theoldmansaidthesunrisesintheeastandsetsinthewest、在主语从句表语从句和同位语从句中也要注意从句谓语动词与主句谓语动词的时态一致性。关键要注意动作发生的先后关系。如:()Whowillbesentabroadhasnotbeendecided(主句是现在完成时从句是一般将来时)()Theearthoftodayisnotwhatitwasmillionsofyearsago(主句是一般现在时从句是一般过去时)在动词think,believe,expect,suppose,guess等后带that宾语从句时若从句是否定句常将否定词not转移到主句中。如:、宾语从句的否定转移:Idon’tthink(that)itwillbecoldtodayWedon’tthinkyoucandoit,canyou注意:这类句子后若带有附加疑问句应采用肯定形式来后问后问部分应于从句主语一致。Idon’tbelievesheknowit,doesshe、几组易混引导词的区别。()What与that在句词性从句中what和that都可作关连词其区别在于:what在从句中要充当某个成分(主语、宾语或表语等),因此在任何情况下都不能省略表示“什么”所…的事(物、话)相当于thethingthat或which。that本身没有词汇意义在名词从句中不充当任何成分在口语和非正式文体中宾语从句中的that经常省略。如:()Whatyouhavedonemightdoharmtoothers()Whatcausedtheaccidentisacompletemystery()Ithink(that)youwilllikethestamps、whether与ifwhether与if在前面已经说过、because与whybecause与why均可引导表语从句但含义不同。because引导的表语从句说明理由。而why引导的表语从句是在前面已说明了理由的情况下加以小结。如:()Ithinkit’sbecauseyou’redoingtoomuch()HewasillThatiswhyhewaslateforschool()Thereasonwhyhewaslatewasthathewasill、Myhometownisnolongeritusedtobe()练习题:A、thatB、whatC、whenD、whichB、Theywondertheirsonwasgettingalongwithhisstudy()A、whetherB、thatC、whatD、howD、heislivingnowisnotknowntoanybody()A、WhenB、IfC、WhetherD、WhyC、Thefactwewereinterestedinallofthem()A、thatwassurprisedB、whichsurprisedC、whatwassurprisedD、whensur
