英语名词性从句,NounClause,起名词性作用的从句，叫名词性从句。换言之，在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语部分，换由一个句子来充当，这样的句子就是名词性从句。,请思考,定语从句的定义：,起定语作用，用来修饰名词或代词的从句。,名词性从句定义,名词性从句,名词性从句在功能上相当于名词,主语,Hisjobisimportant.,Whathedoesisimportant.,表语,Thisishisjob.,Thisiswhathedoeseveryday.,宾语,Idontlikehisjob.,Idontlikewhathedoeseveryday.,同位语,Idontknowabouttheman,Mr.White.,Idontknowaboutthefactthatheisateacher.,连接副词（4个）：when、why、where、how,引导词,从属连词（3个）：that、if、whether,连接代词（9个）：who、whom、what、which、whose、whoeverwhomever、whatever、whichever、,一主语从句,主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。,1.It作形式主语,It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。例如：Itisapitythatyoudidntgotoseethefilm.Itdoesntinterestmewhetheryousucceedornot.,二宾语从句,宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词(及物动词)或介词之后。,1.作动词的宾语(1)由that引导的宾语从句(that通常可以省略),例如：Iheardthathejoinedthearmy.(2)由what,whether(if)引导的宾语从句，例如：Shedidnotknowwhathadhappened.Iwonderwhetheryoucanchangethisnoteforme.(3)动词间接宾语宾语从句。例如：Shetoldmethatshewouldacceptmyinvitation.,2.作介词的宾语，例如：Oursuccessdependsuponhowwellwecancooperate(合作）withoneanother.,3.作形容词的宾语，例如：Iamafraid(that)Ivemadeamistake.Iamsure(that)hewillwinthegame.,4.it可以作为形式宾语it不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that从句则放在句尾，特别是在带复合宾语的句子中。例如：Wethoughtitgoodnewsthatthefoghadfinallygone.,三表语从句,表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语连系动词表语从句”。可以接表语从句的连系动词有be,look,remain,seem等。另外，常用的还有thereasonisthat和Itisbecause等结构。例如：1)Thequestionis_wecanmakegoodpreparationinsuchashorttime.2)Thisis_wecantgetthesupportofthepeople.3)Butthefactremains_wearebehindtheotherclasses.4)Thereason_heislateforschoolis_hemissedtheearlybus.,whether/how,why,that,why,that,四同位语从句,1.同位语从句的功能同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：1)Thekingsdecisionthattheprisonerwouldbesetfreesurprisedallthepeople.2)Theorderthatallthesoldiersshouldstaystillisgivenbythegeneral.,同位语从句就是在复合句中作名词的同位语的名词性从句。,2.同位语在句子中的位置同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：HegotthenewsfromMarythatthesportsmeetingwasputoff.,同位语从句常用名词有belief,chance,doubt,fact,hope,idea,information，news,opinion,possibility,question,result,suggestion,thought,truth,wish等等。常用连词：that/when/where/why和how等等。e.g.消息传来，拿破仑要来视察他的军队。WordcamethatNapoleonwouldcomeandinspecthisgrandarmy.问题是他是如何做这件事的。Itsthequestionhowhedidit.,连接副词（4个）：when、why、where、how,引导词,从属连词（3个）：that、if、whether,连接代词（9个）：who、whom、what、which、whose、whoeverwhomever、whatever、whichever、,名词性从句引导词的用法（1）：,从句中的每一个引导词都有3个功能，分别如下:,从属连词,“that”-无词义、不作成份、起连接作用,“if”-“是否”、不作成份、起连接作用,“whether”-“是否”、不作成份、起连接作用,1、Thatwewillrealizeourdreamsinthefutureiscertain.2、ThefactisthatBeijingwillhold29thOlympicGamesthisyear.3、Iknowthatwellbegunishalfdone.4、HeheardthenewsthatLiuxiangsetanewworldrecord.,“that”-无词义、不作成份、起连接作用,（主语从句）,（表语从句）,（宾语从句）,（同位语从句）,1、Myideaisthatweshoulddoitrightnow.,2、Shewontbelievethathehasbecomeathief.,3、Thatheisafamoussingerisknowntous.,4、Iknewthenewsthatourteamwonthematch.,5、Hissuggestionisthatweshouldfinishtheworkatonce.,说出从句部分及类别并翻译：,同位语从句,表语从句,表语从句,主语从句,宾语从句,1、Whethershewillcomebackontimedependsonweather.2、Theproblemiswhetheryoucouldgiveussomevaluableadvice.3、Iaskedhimwhetherhecoulddomeafavor.4、CouldyoutellmethequestionwhetherEnglishisusefulforusnow.,“whether”-“是否”、不作成份、起连接作用,（主语从句）,（表语从句）,（宾语从句）,（同位语从句）,If只能引导两种名词性从句：宾语从句、不放于句首的主语从句。Whether四种从句均可以引导。,If与whether的区别：,1、Whethershewillcomebackontimedependsonweather.2、Iaskedhimwhetherhecoulddomeafavor.,请思考：,1、Itdependsonweatherifshewillcomebackontime.,2、Iaskedhimifhecoulddomeafavor.,1、If不能引导放于句首的主语从句，而whether可以。2、引导表语从句用whether，不用if。3、引导同位语从句用whether，不用if。4、whether可以引导从句作介词的宾语，不用if。5、whetherornot连在一起可以，但if不可以。而“whether-ornot=if-ornot”,If与whether的区别：,1、Iaskedher_shehadabike.2._wewillholdapartyintheopenairtomorrowdependsontheweather.3.Wereworriedabout_heissafe.4.Idontknow_heiswellornot.5.Idontknow_ornotheiswell.6.Thequestionis_heshoulddoit.7.Thedoctorcanhardlyanswerthequestion_theoldmanwillrecoversoon.,if/whether,Whether,whether,whether/if,whether,whether,请用if/whether填空：,whether,连接代词（9个）：who、whom、what、which、whose、whoeverwhomever、whatever、whichever、,“who”-“谁”、作主语、起连接作用,1、Whowillgotothecollegeisstilluncertain.2、Thetroubleiswhocouldlendmesomemoney.3、Hewanttoknowwhopickeduphismobilephone.,（主语从句）,（表语从句）,（宾语从句）,1、Whomyouwilllearnfromisworththinkingover.2、ThethingIamanxiousaboutiswhomhewillturntoforhelp.3、Hismotheraskedhimwhomhecouldbelievein.,“whom”-“谁”、作宾语、起连接作用,（主语从句）,（表语从句）,（宾语从句）,1、WhatIdesiretogetisagoodreputation.2、WhathewilltellmeiswhatIhavebeenexpectingtoknow.3、TheyagreewithwhatIsaidjustnow.,“what”-“事情”、作主表宾语、起连接作用,（主语从句）,（表语从句）,（宾语从句）,1、Whichclassissuitableforusisntmostimportant.2、Whathewantstoaskyounowiswhichteamwonthegame.3、Couldyoutellmewhichoneisright.,“which”-“哪-”、作定语、起连接作用,（主语从句）,（表语从句）,（宾语从句）,1、Whosebagwasthemostbeautifulisstillunknownnow.2、Thequestioniswhosefriendscouldlendmeahand.3、Iwanttoknowwhosesuggestionismorepractical.,“whose”-“谁的”、作定语、起连接作用,（主语从句）,（表语从句）,（宾语从句）,“whoever”-“-的任何人”、作主语、起连接作用,1、Whoevercouldsolvetheproblemwillberewarded.2、ThepersonIwillpraiseiswhoevercouldworkoutthequestion.3、Youshouldappreciatewhoeverhelpedyouinthepast.,（主语从句）,（表语从句）,（宾语从句）,“whomever”-“-的任何人”、作宾语、起连
