初中英语语法连词专项练习

v1.0可编写可改正初中英语语法连词词专项习题[Because,since,as,for]because,as,for,since这几个词都是表示“原由”的连词，语气由强至弱挨次为：because→since→as→for;此中because,since,as均为附属连词，指引原由状语从句；而for是并列连词，指引并列句。because表示直接原由，它所指的原由往常是听话人所不知道的，其语气最强。常用往返答why的发问，一般放于主句以后，也能够独自存在。例如：(1)Istayedathomebecauseitrained.因为下雨我呆在家里。(2)BecauseLinglingwasill,shedidn'tcometoschool.玲玲因病，没有上学。(3)—Whyissheabsent她为何缺席—Becausesheissick.因为她病了。别的，在重申句型中，只能用because。比如：(4)ItwasbecauseImissedtheearlybusthatIwaslateforschool.我上学迟到是因为我没有追上早班汽车。since重视主句，从句表示明显的或已为人所知的原由，常译为“因为”、“既然”，语气比because稍弱，往常置于句首，表示一种含有牵强语气的原由。比如：(1)Sinceheasksyou,you'lltellhimwhy.他既然问你，那就告诉他为何吧。(2)Sinceeveryoneishere,let'sstart.既然大家都到齐了，我们就出发吧！111v1.0可编写可改正(3)SinceIunderstoodverylittleJapanese,Icouldn'tfollowtheconversation.我日语懂得不多，因此听不懂对话。as是常用词，它表示的“原由”是两方已知的事实或不言而喻的原由，或许原由不是很重要，含义与since同样，但语气更弱，没有since正式，常译为“因为，基于”。从句说明原由，主句说明结果，主从并重。比如：(1)Wealllikeherassheiskind.我们都喜爱她，因为她善良。(2)AsIhadacold,Iwasabsentfromschool.因为我感冒了，所以没去上课。(3)AsXiaowangwasnotready,wewentwithouthim.因为小王没有准备好，我们只能不带他去了。for用作连词时，与because相像，但它所表示的原由常常供给上文未交待过的状况。for不表示直接原由，表示附带或推测的原由，所以for被看作等立连词，它所指引的分句只能放在句子后部(或独自成为一个句子)，而且前后两个分句间的逻辑关系不必定是因果关系，此间用逗号分开，且for不行置于句首，for的这一用法常用在书面语中，较正式。比如：(1)Thedaysareshort,foritisnowDecember.白日短了，因为现在已是十二月份。(2)Itmusthaverained,forthegroundiswet.(从“地面湿润”作出“下过雨”的推测，但地湿其实不必定是下雨所致,for不可以够换为because。)222v1.0可编写可改正(3)Thegroundiswetbecauseithasrained.(“下雨”是“地上潮湿”的直接原由。)前后两个分句间有必定的因果关系时(有时很难划分是直接原由，仍是推测性原由)，for与because能够交换使用。比如：(4)Icouldnotgo,for/becauseIwasill.我没能去，是因为我病了。(5)Hefeltnofear,for/becausehewasabraveboy.他没有害怕，因为他是个英勇的男孩。Because/asbecause指引的是必定原由，as指引一般原由。必定原由是指某事发生必会致使另一件事实。一般原由语气还有其因果关系不是很明显。以下两个句子请体会Theflooriswet,becauseitrainedthismorning.Astheflooriswet,itmightrainthismorning.(地板湿也可能是其余原由，以此看，as指引原由从句还有猜想的意味。)Because/for这两个词的意思很邻近，往常是能够交换使用的。为了安全起见，最好用because引导从句，因为同because指引的从句对比，for指引的从句（英文中称为for－clause）的用法要遇到某些限制：1for指引的从句不可以位于它所解说的动词之前：Becauseitwaswethetookataxi．因为下雨，他叫了一辆出租车。（这里不可以用for。）2for指引的从句不可以位于not，but或任何连词以后：333v1.0可编写可改正Hestole，notbecausehewantedthemoneybutbecausehelikedstealing．他偷东西，其实不是因为他想要钱，而是他有这类缺点。（这里不可以用for。）3for指引的从句不可以用于回答下列问题：—Whydidyoudoit—IdiditbecauseIwasangry．—你为何这么做—因为我生气才这么做的。（这里不可以用for。）for指引的从句不可以单单用来复述已讲过的话，而一定包含新的内容：HespokeinFrench．ShewasangrybecausehehadspokeninFrench．他讲法语。因为他讲法语，她生气了。（这里不可以用for。）可是能够说：Shewasangry，forshedidn’tknowFrench．她生气了，因为她不懂法语。（这里用for是正确的，也可用because。）之所以有这些用法上的限制，其原由是for指引的从句不可以直接说明某一特定动作发生的原由，而只能供给一些起帮助解说作用的附带说明。例句如：Thedayswereshort，foritwasnowDecember．天短了，此刻已经是12月了。Hetookthefoodeagerly，forhehaseatennothingsincedawn．他风卷残云地吃了起来，因为他从天亮就没吃过东西。444v1.0可编写可改正Thewomanwas____angry_____shecouldn'tspeakanything.thatWeheardclearly_____shesaid.---Canyouplayfootball555v1.0可编写可改正17._________John_______Iarepolicemen.A.Neither...norB.Either...orC.Both...andD.Notonly...butalsoMrSmithteaches______well______hislessonsarenoteasilyforgotten.A.very...thatB.quite...butC.so...asD.so...thatHedidn'tgotosleep______hefinishedhishomework.Therunnerfell_______hequicklygotupandwentonrunning.Itwaslate.Shewashedherface______wenttobed.shoutedaloud______heranalone.returnthebooktome_____youcomeback.A.assoonas29..Ringmeup____youcometomyhouse.D.then.30.Imuststopwritingnow,______Ihaveratheralotofworktodo.666v1.0可编写可改正D.sincebusdidn’tleave_____everyonegeton.’llleaveamessage_____hewillknowwhereweare.A.sothatB.assoonasC.forD.that33.Mysisteris____young____hecan’tgotoschool.A,too,toB.enough;toC.sothatD.as;as34.Hisbrothergotupearlier____hecouldcatchthebus.A.asifB.soC.sothatD.than35.Itisalmostthreeyears____Isawhelast.A.whenD.that’mgoingtothesupermarket.----Willyougetmesomechocolates____youarehere,mum.A.sinceBbecauseCifD.while37.MrGreencametoChinain2000,______hehaslivedhereeversince.A.andB.orC.butD.for38.____theyarebrothers,theydon’tlooklikeeachotheratall.A,BecauseB.ThoughC.WhenD,As39.Iknownothingaboutit____mybrothertoldmeyesterday.C.untild.so40.Hefailed_____becauseheisn’tclever______becausehedidn’tworkhard.A.notonly..butalsoB.both.andC.eitherorD.notbutteacherwonderedwhyhehad____questions.A.somuchB.somanyCsuchmuchD.suchmany42.Wewereswimminginthelake____suddenlythestormstarted.777v1.0可编写可改正A.whenB.whileCuntilD.before43.Wecan_____see____touchtheair.A.notonly,butalsoB.both,andC.either,orD.neither,nor44.Youcan____stayathome_____gotomyhometownwithme.A.not,onlyB.eitherandC.bothorD.eitheror45.Weleftin_____ahurry_____weforgottolockthedoor.A.so,soB.so,thatC.such,thatD.suchso46.__Judy,youlooksotired.__Yes.Ididnotgotobed____itwastwelvelastnight.47.Shewassointerestedinthebookthatshehasreaditforthreehours____sherealizedit.48.Jackspendmuchmoneyonbooks____heissorich.49Johnfeelasleep____hewaslisteningtothemusic.Shedoesnotfeellikeplayingbasketballnow,____,sheisnotgoodatit.51.Motherisill,_____Fathercookedforusinstead.C.so’s9o’clocknow.Imustgo.-----It’srainingoutside.Don’tleave_____itstops.D.untilyouliketogototheconcertwithme-----I’dloveto______Ican’t.888v1.0可编写可改正D.and54.---Ourholidaycostalotofmoney.----DiditWell,thatdoesn’tmatter____youenjoyedyourselves.A.ifBunlessCwhileD.ordidn’tcometoschoolyesterday,____he
