大家论坛club.topsage.com新概念英语第三册语法精粹(一):定语从句新概念三册语法精粹第一章定语从句 1.定语从句:由关系代词who,whom,whose,that,which;关系副词when,where,why引导。 (下面十个句子请读5遍并脱口译出!) 1.Thedeathnoticestellusaboutpeoplewhohavediedduringtheweek. 2.Theman(whom)youspoketojustnowismyfriend. 3.Thebuildingwhoselightsareonisbeautiful. 4.Pleasefindaplacewhichwecanhaveaprivatetalkin. 5.Thekneeisthejointwherethethighbonemeetsthelargeboneofthelowerleg. 6.Hestillremembersthedaywhenhewenttoschool. 7.Itisnoneedtellingusthereasonwhyyoudidn'tfinishitintime. 8.Hehasthreesons,twoofwhomdiedinthewar. 9.Mr.Smith,whosewifeisaclerk,teachesusEnglish. 10.IntheSundaypapertherearecomics,whichchildrenenjoy. 2.只能用that和who引导的定语从句  大家论坛club.topsage.comA.all,nothing,anything,afew,one做先行词指物时 B.先行词前有形容词最高级修饰时,后面常跟that而不是which. C.先行词前有theonly,thefirst,thelast,thenext,thevery等词修饰时,引导词只能用that。 D.当先行词是anyone,anybody,everyone,everybody,someone,somebody时,后面要用who或whom; ●Allthatglittersisnotgold.闪光的并非都是金子。 3.as引导定语从句 as引导的定语从句有两种形式: A.引导限制性语从句。在此类定语从句中,as常与主语中作为其先行词的such,thesame或as联用构成,“such...as”,“thesame...as”和“as...as”句型,可代替先行词。 例如:Wehopetogetsuchatoolasheisusing.我们希望得到他正在用的那种工具。 B.as引导非限制性定语从句时,作用与which相同,as作为关系代词代替整个主句。   (这是语法考试的一个考点。) [注意区别]: as引导的从句用于句首、句中或句后,而which引导的定语从句不能放在句首。 例如:Asisreported,aforeigndelegationwillvisitthecity. 大家论坛club.topsage.com 据报道,一个外国代表团将访问这个城市。新概念英语第三册语法精粹(二):状语从句新概念英语第三册语法精粹(二):状语从句 超级作文联接词及词组,全部拿下! ①原因:because,since,nowthat(既然)as,for,thisreason.... ②结果:sothat,so,therefore,consequently,soasto,asaresult.... ③时间:after,before,when,while,as,until,assoonas,since,bythetime,once,lately,presently,shortlyafter,currently,atpresent,nowadays... ④条件:if,onlyif.,once,unless,intheevent(that),incase(that),providedthat,ontheconditionthat,etc. ⑤让步:though,although,eventhough(if),nomatterwhat/how/when→whatever/however/whenever.... ⑥目的:inorderthat,inorderto,to, ⑦比较:than,as...as,bycomparison(相比较),bycontrast(相对照)....新概念英语第三册语法精粹(三):名词性从句新概念英语第三册语法精粹(三):名词性从句 王牌要点:通常由that或疑问词导出。1.Howsomemammalscametoliveintheseaisnotknow.(主语从句)  大家论坛club.topsage.com2.Theattorneytoldhisclientthattheyhadlittlechanceofwinningthecase.(宾语从句) 3.Theproblemiswhatwe'lldonext.(表语从句) 4.Wehavenoideathathehascomeback.(同位语从句) 同位语(Appositive): 同位语是英语语法的重点内容,也是各类考试中的一个考点,同时,在写作中正确运用同位语可以使你的句型更加简洁得体。 《新概念英语》第三册第一课有这样一个句子:WhenreportscameintoLondonzoothatawildpumahadbeenspottedforty-fivemilessouthofLondon,theywerenottakenseriously. (当伦敦动物园接到报告说,在伦敦以南45英里处发现一只美洲狮时,这些报告并没有受到重视。) 在这里,awildpumahadbeenspottedforty-fivemilessouthofLondon就是同位语从句,它本来应该放在“reports”后面,这里却被放在了谓语成分cameintoLondonzoo的后面,目的是让句型显得更为稳重。I.简单记忆:同位语从句,就是对某些名词做进一步的解释的句子。IwasgreatlyshockedwhenIheardthenewsthathisfatherdiedyesterday. (that引导的句子解释了news的内容,注意:that不做任何成分) Wehavetofacethefactthattheweatherisunexpectedlybad. (that引导的句子解释了fact的内容) 大家论坛club.topsage.comII.联想记忆: 能接同位词从句的名词有:belief(信仰),fact,idea,doubt,rumor(谣言),evidence(证据),conclusion(结论),suggestion(建议),problem,order,answer,discovery(发现)explanation(解释),principle(原则),possibility(可能性),truth,promise(承诺),report(报告),statement(声明),knowledge(知识),opinion(观点),likelihood(可能性) [大声朗读三遍,背下即可。] III.王牌要点: ●同位语一般由that引导,但也可以用关系代词which,who,what和关系副词when,where,why,how或whether引导。   Therearousethequestionwhetherwecouldwinthegame.   Ihavenoideahowtoexplainit. ●一些介词词组后面也能引导同位语从句。(非常经典之功能句式,可用于四六级和托福作文,不妨一试!):   ontheassumption(在……前提下),   ontheground(由于……原因),   ontheconditionthat(在……条件下),   withtheexception(有……例外) 大家论坛club.topsage.com   owingtothefact(由于……事实);   ontheunderstanding(基于……理解);   Theyoungladypromisedtomarrytheoldmanontheconditionthatheboughtheravilla.   那位年轻的女士答应嫁给那位老头,条件是他给她买一幢别墅。IV.分隔式同位语从句 为了使句型平衡不至于头重脚轻,有时同位语从句可以放到句子的末尾,(读两遍此定义,然后看倒句:) Anideacametohimthathemightwritetohertoaskmoreinformationaboutthematter. IgotinformationfrommyfriendthattherewillbeamarvelousAmericanmovie"Titanic".V.同位语从句与定语从句之区别 简单记忆:定语从句的引导词that或which在句子中用作主语或宾语,而同位语从句的引导词that只起连接主句和从句之作用,不用作任何成分。 示例:I'vegotananswerthatAisright.(同位语从句,that不做成分) I'vegotananswerthatsurprisedmealot.(定语从句,that做定语从句的主语) VI.王牌重点:可以充当同位语的词组或短语。 1)名词短语。(使句型更为简洁)  大家论坛club.topsage.comBillClinton,thepresidentofAmerica,cametoChinatopayanofficialvisitin1998. LuXun,oneofthegreatestessayistsinChina,playedanoverwhelminglyimportantroleinChineseliteraturehistory. 2)动名词词组亦可用作同位语:别忘了加逗号。(使句型更为流畅) I'mcrazyaboutthegame,playingbaseball. Goingtoconcert,thatsoundsagreatidea. 3)不定式短语。(陌生只是掌握的开始) Theproblemwhattodonextremainsunsolved. Herclaimtohavefinishedhisworkisnothingbutawhitelie. 4)形容词词组。(有逗号隔开) Alltheworkers,youngorold,shouldbetreatedequally. Youngman,shortortall,shouldhavetherighttotaketheopportunity. VII.同位语的引导词。(重要!这是中高级写作中不可缺少的引导成分) 引导词用来表示同位语与它所说明的同位成分之间的关系: 1.namely,thatitis,thatistosay(也就是说),inotherwords(换句话说),or,forshort表示等同关系。  大家论坛club.topsage.com2.suchas,say,sotospeak(譬如说),including(包括),forinstance(或forexample(e.g./eg),表示举例和列举关系。 3.especially,mostly,chiefly,orbetter,inparticular,particularly表示突出重点,(在高难度阅读中表示后面的部分为更重要或更突出的部分,是出题的关键点。)新概念英语第三册语法精粹(四):虚拟语气新概念英语第三册语法精粹(四):虚拟语气 虚拟语气用来表达不可能或难以实现的愿望,与事实相反的假设,通常分为基本的三种形式。 1.与现在事实相反的虚拟: If+did/were+...,...would should could         +do(动词原形) might IfIwereyou,Iwouldgoabroadatonce.(Iamnotyou.) Ifheknewitnow,hecouldhelpme.(Hedoesn'tknowitnow.) 2.与过去事实相反的虚拟: If+haddone+...,...would(might)havedone... IfIhadknownyourtelephonenumberyesterday,Iwouldhavephonedyou.
