英语平行结构和比较结构课件

英英语平行平行结构和比构和比较结构构Parallelism&Comparison1编辑课件连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。并列连词用来连接平行的词、词组和分句。从属连词用来引导名词从句和各类的状语从句。一、平行结构,即并列结构：由并列连词连接两个或两个以上对等的语言成分构成。2编辑课件并列并列结构的构的连接手段接手段）并列连词）标点符号）并列结构的插入语在最后一个项目之前插入一个词语，使这个项目处于更加突出的地位。）并列结构的对称组合成对组合的办法使整个结构更加紧凑。3编辑课件常见的并列连词有：1、表递进关系：and,notonlybutalso,neithernor,notbut2.选择关系：or，eitheror,otherwise,whether.or3.转折对比关系:but,yet,whereas,while,still4.因果关系：so,for5.并列关系：and,when4编辑课件一、表示平行、递进关系的连词1.AandBAnd连接两个并列成分。and也常位于句首，使上下文联系更紧密。Thefabricislightandstrong.Ilikereadingandfishinginmysparetime.Thismodelofthecomputerispowerful,andthepriceiscompetitive.Itwasaseverewinter.Andwehadnotenoughfoodforourselves.5编辑课件2.bothAandB这一结构是and的强化形式，连接的两个成分必须在结构上等同。不能连接句子。Thenewtaxpolicybenefitsbothworkersandfarmers.BothesheandIareinterestedinEnglishliterature.6编辑课件3.notonlybut(also)不仅而且notonlybutaswell不仅而且也aswellas和andaswell和*notonlybut(also)结构构侧重在后者，而重在后者，而aswellas侧重在前者。重在前者。NotonlyGeorgebutalsohiswifedidalotforus.Itissaidthathecanflyaplaneaswellasdriveacar.Shecanplaypopmusicandclassicalmusicaswell.7编辑课件二、表示二、表示选择关系的关系的连词1.neitherAnorB这一结构表示否定意义，若连接两个句子可以采用倒装形式。Einsteincaredforneithermoneynorfame.Youcanneithertakeitoutnorphotocopyit.*在否定结构中通常用or连接两个并列成分。Youcannevertakeitoutorphotocopyit.8编辑课件2.or或者，大约，否则，不然eitheror或者.或者，不是就是(eitheror结构是or的强化形式)Doyoustayathomealoneorgototheatrewithme?Youllhavetowaitoneortwodaysbeforeyouknowtheresult.Hurryup,orwellbelate.Haveonemoretry,oryouwontbesuccessful.Eitherhedidntspeakclearlyoryoudidnthearwell.9编辑课件三、表示三、表示转折和折和对比意比意义的并列的并列连词but（但是），yet（然而），while（而，却）等Afterabusyday,Ifelttiredbuthappy.Difficultieswillariseinthecourseofreforming，butwewillcertainlyovercomethem.Hewasnotfeelingwell,yethekeptonuntilitwasdone.Chinaisrichinnaturalresources,whileJapanispoor.10编辑课件四、表示因果关系的并列四、表示因果关系的并列连词so（因此，所以），for（因为）Manydirectorswereabsent,sothemeetinghadtobepostponed.Hemusthavedonesomethingwrong,fortheheadteachercalledhimtotheoffice.*so不能与because同时出现在同一句中。For从句主要是对前面的句子作出解释或进行推断，因此for引导的句子不能用于句首。11编辑课件1.Tomistall_hisbrotherisshort.2.Shegotupearly,_shefailedtobethereontime.3.Itisnotwrongofpeopletopursuewealth;_,theyshouldalsotrytolearntofulfilltheirknowledge.4.Someonemustbecoming,_thedogisbarking.5.Thatwasourfirstlesson,_shedidntknowallournames.whilebutyetforso12编辑课件1.OnedayJohnwaslate,_hismissedthefirstclass.2.Notonlydidhespeakmorecorrectly,_hespokemoreeasily.3.Thechildrencangowithus,_theycanstayathome.4.Youmusttellthetruth,_youwillbepunished.5.Eitheryoucandoitbyyourself,_youcanasksomeoneelsetohelpyou.6.Doyouhaveatablefortwo?-Imsorry,_therearentanyseatsnow.andbutalsoorororbut13编辑课件PairedconjunctionsDirections:Addisoraretoeachsentence1.Boththeteacherandthestudent_here.2.Neithertheteachernorthestudent_here.3.Notonlytheteacherbutalsothestudents_here.areisare14编辑课件ErrorAnalysis:PairedConjunctions1.EitherJohnwillcallMaryorBob.1.JohnwillcalleitherMaryorBob.2.NotonlySuesawthemousebutalsothecat.2.Suesawnotonlythemousebutalsothecat.3.Ienjoynotonlyreadingnovelsbutalsomagazines.3.Ienjoyreadingnotonlynovelsbutalsomagazines.4.Oxygenisplentiful.Bothaircontainsoxygenandwater.4.Oxygenisplentiful.Bothairandwatercontainoxygen.15编辑课件并列并列结构的构的标点符号点符号由两个以上项目构成的并列结构通常只在最后一个项目之前用并列连词，其他项目之间用逗号连接。Therearefivetypesofdischargefrommilitaryservice:honorable,general,undesirable,badconduct,anddishonorable.两个以上项目全用连词连接起来的并列结构，在修辞色彩上给人以悠闲缓慢、延续持久的感觉。Raisingvegetablespresentsendlessopportunitiesforweedingandthinningandhoeingandwatering.16编辑课件有时也可全用逗号，在修辞色彩上给人以紧张、急促、明快、利落的感觉。除了逗号，分号和冒号也能起并列连词的作用。分号连接两个并列分句，通常表示对比关系。Golfdemandsthebestoftimeandspace;tennis,thebestofpersonalenergy.用冒号连接两个并列分句，通常表示下文是对上文的解释和发挥。Hijackersandkidnappersoffertwoequallyimpossiblealternatives:arefusaltomeettheirtermsmaymeandeathfortheirvictims;meetingtheirtermsmaymeanmorevictimsinthefuture.17编辑课件在某些连接性副词如accordingly,furthermore,hence,however,nevertheless,therefore等之前通常要用分号，而不用逗号。Hehadworkedintheforeignservicefortwoyearswithoutleave;hencehewastiredalmostbeyondendurance.FromarunningstartPedrolaunchedhisbodyintoavigorousracingdrive;however,hewasaboutthirtyfeetfromthepoolatthetime.18编辑课件二、对连接词连接的成分要求：形式对称；功能相同（充当同样的句子成分），时态平衡。并列平行结构应该是名词和名词，副词和副词，分词和分词，不定式和不定式，动词和动词，句子和句子等的并列，而不能其中一个概念用分词结构表达，而另一个概念用不定式或从句来表达。比如下面句子就违反了平行结构的准则：Dosomenicethingsforyourparentsthattheydontexpectlikecooking,doingthedishes,washingclothes,orcleanthefloors.“做饭”、“刷碗”、“洗衣服”、“拖地”在本句中应为并列结构作为介词like“像”的宾语，故应用相同的形式，都用动名词，所以应将clean改为cleaning。19编辑课件三、平行结构主要类型1.名词和名词平行结构Thepatientssymptomswerefever,dizziness,andheadache.病人的症状是发烧、头晕和头痛。2.形容词和形容词平行结构Earlytobedandearlytorisemakesamanhealthy,wealthyandwise.早睡早起使人健康、富有、聪明。20编辑课件三、平行结构主要类型3.副词和副词平行结构Theworkishandsomelyandskillfullydone.这项工作做得漂亮，有水平。4.分词平行结构(现在分词与现在分词/过去分词与过去分词)Theboyswererunning,shoutingandlaughing.男孩子们边跑，边喊叫着、笑着。（伴随状语）Theoldmanreturnedhome,disappointedandexhausted.21编辑课件5.动名词doing平行结构Henrysworkisreadingbooksandwritingbookreviews.亨利的工作是读读书，写写书评。6.动词不定式平行结构Ontheotherhand,40%thinkthatfeesshouldbechargedbecauseyouneedmoneytopaygardenersandotherworkers,and(to)buyplantsandyoungtrees.另一方面，40%的同学认为应收门票，他们认为门票费可以作为支付园林工人及其他工作人员的工资和购买新花木的费用。and连接并列不定式第二个不定式往往省接并列不定式第二个不定式往往省略略to。22编辑课件7.介词短语平行结构1）Yoursemestergradeisbasednotonlyonhowwellyoudooneachtest,butalsoonhowyouparticipateinclass.2）Weoftengotothecountrysideaswellastofactories.8.谓语动词平行结构谓语形式形式时态要一致要一致Hewentdowntown,boughtsomebooksandvisitedhisdaughter.9.句子的并列（并列句）Iwastired,butIfelthappy.23编辑课件ErrorAnalysis:ParallelStructure1.Byobeyingthespeedlimit,wecansaveenergy,lives,anditcostsusless.1.Byobeyingthespeedlimit,wecansaveenergy,livesandmoney.2.Myhomeoffersmeafeelingofsecurity,warm,andlove.2.Myhomeoffersmeafeelingofsecurity,warmth,andlove.24编辑课件3.Thepioneerslaboredtoclearawaytheforestandplantingcrops.3.Thepioneerslaboredtoclearawaytheforestandplantcrops.4.WhenIrefusedtohelpher,shebecameveryangryandshoutatme.4.WhenIrefusedtohelpher,shebecameveryangryandshoutedatme.25编辑课件5.Inmysparetime,Ienjoytakingcareofmyaquariumandtoworkonmystampcollection.5.Inmysparetime,Ienjoytakingcareofmyaquariumandworkingonmystampcollection.6.Withtheirkeensight,finehearing,andtheyhavearefinedsenseofsmell,wolveshuntelk,deer,moose,andcaribou.6.Withtheirkeensight,finehearing,andrefinedsenseofsmell,wolveshuntelk,deer,moose,andcaribou.26编辑课件7.Allplantsneedlight,tohaveasuitableclimate,andanamplesupplyofwaterandmineralsfromthesoil.7.Allplantsneedlight,asuitableclimate,andanamplesupplyofwaterandmineralsfromthesoil.27编辑课件英英语比比较句型句型28编辑课件原级的句型“as+原原级形容形容词/副副词+as”的结构，表示前后两者的情况一样1）“A+系系动词+as+形容形容词原原级+as+Beg.Billisasfunnyashisfather.Myhandwritingisasbeautifulasyours.我的书法和你的一样好。2）“A+谓语动词+as+副副词原原级+as+B”eg.LucyspeaksChineseaswellasLily.29编辑课件在否定句中，用“notas/so+原原级形容形容词as”结构，表示前者不如后者。“A+系系动词+notasso+形容形容词原原级+as+B”eg.Thesebooksarentasinterestingasthose.Iamnotas/sobusyasIusedtobe.我没有过去那么忙了。区区别：TomisnotastallasMike.TomisnotsotallasMike.“A+助助动词情情态动词+not+谓语动词+asso+副副词原原级+as+B”eg.Shedidntsingsowellthatnightassheusuallydoes.30编辑课件thesame()as与与相同相同/同同样YouvemadethesamemistakeasTom.有有时thesame可以可以单独使用：独使用：Mymotherismuchyoungerthanyours.Sheisnt!Theyreaboutthesameage.Thosetwodressarethesame.differentfrom与与不同不同（different前面可加very，much，alittle等修饰语）IsFrenchfoodverydifferentfromItalianfood?Wereplanningsomethingdifferentthisyearfromwhatwedidlastyear.31编辑课件常用词组1.asgoodas几乎已几乎已经，实际上等于，和上等于，和几几乎乎一一样Heisasgoodasdead.他跟死了一样。Thesecondhandgeographybookisasgoodasnew.这本二手地理书几乎还是新的。2.assoonas一一就就PleaseletusknowassoonasyouarriveinBeijing.一到北京，请通知我们一声。Assoonasshegothome,shebegancooking.她一到家就开始做饭。32编辑课件3.asmuch/manyas多达多达，达到，达到之多，之多，实际上等于，差不多上等于，差不多Someofthestonesevenweighasmuchasfifteentons.有些石块甚至重达15吨。Thenumberofpeoplewholosthomesreachesasmanyas250,000.失去家园的人数多达25万。Thatsasmuchastosayhewasathief.那无异于说他曾是个小偷。4.asfaras就就而言，尽而言，尽AsfarasIknow,hellbeawayforthreemonths.就我所知，他将离开三个月。Wewillhelpyouasfaraswecan.我们会尽力帮助你。33编辑课件5.aslongas只要只要Youcangowhereyoulikeaslongasyougetbackbeforedark.你去哪儿都可以，只要你在天黑前返回。YouwillbehappyaslongasIamliving.只要我活着，你就会幸福。6.asoftenas每当，每次每当，每次Asoftenashecame,hewouldstaywithusforatime.每次他来，总要和我们呆上一阵子。TheboyalwayssayshellotomeasoftenasImeethim.每次我遇见那个小男孩，他总是向我问好。34编辑课件7.aswellas和，同，既和，同，既又又，不，不仅而且而且Myparentsaswellasmyelderbrotherenjoymusic.我父母亲和我哥哥都喜欢音乐。Heiscleveraswellashardworking.他不仅努力工作而且聪明。8.asaspossible/onecan尽可能，尽（某人）尽可能，尽（某人）所能所能Pleasesweepthefloorascleanaspossible.请把地打扫得尽可能干净。IllgetbackassoonasIcan.35编辑课件
