这些连词均含有“因为”之意as,because,for,since这些连词均含有“因为”之意。as：附属连词，语意较because,since弱，着重在主句，所表示的原因或理由是"附带的"。because：附属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以答复why提出的问题。for：并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。since：语意比because弱，但比as强，一般用于表示"由于大家的事实"。as,like这两个词均有“像”之意。as：附属连词，引出方式从句。like：是前置词，后面跟的是宾语。though,although,as这些连词均可表示“虽然，尽管”之意。though和although在意义上几乎毫无区别，但文体上后者是较正式用词，语气比though强。此外，在习惯用法上这两个词仍有以下一些差异：1.though可引出倒装语序的让步状语从句，although那么不能。2.though可与even连用，although那么不能；在asthough结构中，只用though，不能用although。3.though可以置于从句末，而although那么不能。4.引出省略句时，通常用though。as：引出让步状语从句只用于倒装语序结构中，语气强于上述两个连词。when,while,as这些连词均可表示“当……时”引出时间从句。when：所引导的从句，其谓语动词既可是持续动词，也可是短暂动词；谓语动词动作发生的时间可以与主句谓语动词的动作是同时，或之前、之后。while：句中的谓语动词应为持续动词，不用短暂动词，谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。as：侧重指从句与主句的动作同时进行，谓语动词可以是持续性的，可以是短暂性动词。1】用作副词(adv.)1.Sheisastallashermother.她和她母亲一样高。2.HerunsasfastasPaul.他跑得和保罗一样快。3.Adedoesn'tplayhalfaswellasCage.艾德演奏的水平不及凯奇的一半。4.Smithworksashardasyouusedto.史密斯和你从前一样工作努力。5.Returnasmuchmoneyasyouborrowed.借多少就还多少。6.YoumustspeakEnglishasmuchaspossible.你必须尽量多说英语。7.You'vemadeasmanymistakesasIhave.你犯的错误和我一样多。8.Theyarehavingalmostasmuchunemploymentasweare.他们的失业者几乎和我们一样多。9.ThediningroomwastwiceasbigastheTom's.这个餐厅是汤姆的餐厅的两倍大。10.Thisisasdifficultaproblemasyouarelikelytomeet.像这样的难题,你可能会碰到。11.ItwasaspleasantadayasIhaveeverspent.那一天我和往常一样过得愉快。12.Heisn'tquitesooldasshe.他还没有到她那样老的年纪。13.Heisnotasoldasshe,butolder〔younger〕thanshe.他并不是和她同样年纪，而是比她老〔年轻〕些。14.I'mnotasconceitedassomanypeopleseemtothink.我不像很多人认为的那么自负。15.She'ssmart,butherbrotherisjustassmart.她很聪明，但她兄弟也一样聪明。16.Thewomanmarriedamanpoorasherself.这个女人嫁给了一个与她一样穷的男人。9.Hedoesthisjobasaskilledlabour.他做起这个活像个熟手。10.Heappearedasamaninatrance.他显得神思恍惚。11.Wechosethisoneasthemostsuitableforourpurpose.我们之所以选择这一个，因为它最适合于我们的目的。12.Hewishedtojointhearmy,butwasrejectedasmedicallyunfit.他想要参军，但因体检不合格而未被批准。13.It'snotnearlyascoldasyesterday.今天一点儿也不像昨天那么冷。14.Thetwobrotherslookandspeakthesameaseachother.这两兄弟长得一模一样，说起话来也一模一样。15.Don'tregardmeasachild.别把我当成小孩看待。16.Wehadbettertreatitasajoke.我们最好把它当作玩笑。17.Thedykeswerebuiltasaprotectionagainstthesea.建筑堤坝是为了防止海水泛滥。18.Wetalkedaboutsuchsubjectsastheweather.我们谈论了诸如天气之类的话题。【2】用作介词(prep.)1.Asachild,helivedinJapan.他小的时候住在日本。2.Asaschoolboy,heshowedeverysignofgenius.当他还是个小学生的时候,就显示出了天资聪明。3.Heworkedasacashierinabank.他在一家银行干过出纳。4.UnderthenewarrangementIcontinuedasmanager.根据新的安排,我继续担任经理职务。5.Thischaircanalsofunctionasabed.这张椅子可兼做床用。6.Thiswatchwasgivenmeasabirthdaypresent.这只表是作为生日礼物送给我的。7.SheisknownasMary.她叫玛丽。8.Franceisfamousasawine-producingcountry.法国以产酒国著称于世。【3】引导时间状语从句Iwascominginashewasgoingout.我进来的时候,他正出去。MypentremblesasIwriteit.我一边写,笔一边颤抖。Helenheardthestoryasshewashed.海伦洗衣服的时候听了这个故事。AsIleftthehuoseIrememberedthekey.当我离开房间的时候,我想起了钥匙。AsIwascominghere,Imetyourbrother.我来这儿的时候遇见了你哥哥。Theboy'seyeshadslowlymovedtohimashehadspoken.他说完时,这孩子的眼光已慢慢地移到他身上。【4】引导时间状语从句Iwascominginashewasgoingout.我进来的时候,他正出去。MypentremblesasIwriteit.我一边写,笔一边颤抖。Helenheardthestoryasshewashed.海伦洗衣服的时候听了这个故事。AsIleftthehuoseIrememberedthekey.当我离开房间的时候,我想起了钥匙。AsIwascominghere,Imetyourbrother.我来这儿的时候遇见了你哥哥。Theboy'seyeshadslowlymovedtohimashehadspoken.他说完时,这孩子的眼光已慢慢地移到他身上。【5】引导让步状语从句1.ChildasisPaul,heknowsenoughtotellgoodfrombad.保尔虽是个孩子，却已懂得区分好坏。2.Cowardashewas,however,Flashmancouldn'tswallowsuchaninsultasthis.弗拉西曼虽然是个胆小鬼,也不能忍受这种屈辱。3.Simpleaswastheidea,thethenscientificworldwouldhavenoneofit.虽然这概念很简单，但当时的科学界却不知道这一点。4.Intelligentasyouare,Isuspectyouwillfail.尽管你聪明,我还是猜测你会失败。5.Surroundedaswewerebytheenemy,wemanagedtomarchforward.尽管我们被敌人包围了,我们还是决心向前进。6.Quicklyasitspreadandthreateningasitappearedtobe,theresultwasdoomedfromthestart.尽管起义开展很快,声势浩大,但它从开始时起就注定了要失败。7.Hewasunabletomakemuchprogress,hardashetried.尽管他努力了,但他没能取得多少进步。TryasImight,Icouldn'tliftthestone.无论我怎么努力也搬不动这块石头。【6】引导比较状语从句1.Runasfastasyoucan.你能跑多快就跑多快。2.Poetsarenotsoscrupulousasyouare.诗人并不像你那样顾虑多。I'mashappyashappycanbe.我快乐极了。【7】引导方式状语从句1.WheninRome,doastheRomansdo.入乡随俗。2
