英语平行结构和比较结构英语平行结构和比较结构Parallelism&Comparison第1页连词是一个虚词，它不能独立担任句子成份而只起连接词与词，短语与短语以及句与句作用。连词主要可分为两类：并列连词和隶属连词。并列连词用来连接平行词、词组和分句。隶属连词用来引导名词从句和各类状语从句。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语言成份组成。第2页并列结构连接伎俩并列结构连接伎俩）并列连词）标点符号）并列结构插入语在最终一个项目之前插入一个词语，使这个项目处于愈加突出地位。）并列结构对称组合成对组合方法使整个结构愈加紧凑。第3页常见并列连词有：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,when第4页一、表示平行、递进关系连词1.AandBAnd连接两个并列成份。and也常位于句首，使上下文联络更紧密。Thefabricislightandstrong.Ilikereadingandfishinginmysparetime.Thismodelofthecomputerispowerful,andthepriceiscompetitive.Itwasaseverewinter.Andwehadnotenoughfoodforourselves.第5页2.bothAandB这一结构是and强化形式，连接两个成份必须在结构上等同。不能连接句子。Thenewtaxpolicybenefitsbothworkersandfarmers.BothesheandIareinterestedinEnglishliterature.第6页3.notonlybut(also)不但而且notonlybutaswell不但而且也aswellas和andaswell和*notonlybut(also)结构侧重在后者，而结构侧重在后者，而aswellas侧重在前者。侧重在前者。NotonlyGeorgebutalsohiswifedidalotforus.Itissaidthathecanflyaplaneaswellasdriveacar.Shecanplaypopmusicandclassicalmusicaswell.第7页二、表示选择关系连词二、表示选择关系连词1.neitherAnorB这一结构表示否定意义，若连接两个句子能够采取倒装形式。Einsteincaredforneithermoneynorfame.Youcanneithertakeitoutnorphotocopyit.*在否定结构中通惯用or连接两个并列成份。Youcannevertakeitoutorphotocopyit.第8页2.or或者，大约，不然，不然
