初中英语语法连词专项练习

初中英语语法之连词专项练习初中英语语法之连词专项练习初中英语语法之连词专项练习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“原因〞的连词，语气由强至弱依次为：because

→since→as→for;其中because,since,as均为隶属连词，引导原因状语从句；而for是并列连词，引导并列句。1.because表示直接原因，它所指的原因平时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。其他，在重申句型中，只好用because。比方：(4)ItwasbecauseImissedtheearlybusthatIwaslateforschoo我l.上学迟到是由于我没有追上早班汽车。2.since重视主句，从句表示显然的或已为人所知的原因，常译为“由于〞、“既然〞，

语气比because稍弱，平时置于句首，表示一种含有勉强语气的原因。比方：(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！(3)SinceIunderstoodverylittleJapanese,Icouldn'tfollowtheconversation.我日语懂得不多，所以听不懂对话。3.as是常用词，它表示的“原因〞是双方的事实或不问可知的原因，也许原因不

是很重要，含义与since相同，但语气更弱，没有since正式，常译为“由于，鉴于〞。从句说明原因，主句说明结果，主从并重。比方：(1)Wealllikeherassheiskind.我们都喜欢她，由于她和蔼。(2)AsIhadacold,Iwasabsentfromschool.由于我感冒了，所以没去上课。(3)AsXiaowangwasnotready,wewentwithouthim.由于小王没有准备好，我们只好不带他去了。4.for用作连词时，与because相似，但它所表示的原因经常供应上文未交待过的情况。

for不表示直接原因，说明附加或推断的原因，所以for被看作等立连词，它所引导的分句只好放在句子后部(或独自成为一个句子)，并且前后两个分句间的逻辑关系不用然是因果关系，此间用逗号分开，且for不可以置于句首，for的这一用法常用在书面语中，较正式。比方：1(1)Thedaysareshort,foritisnowDecember.白日短了，由于此刻已经是十二月份。(2)Itmusthaverained,forthegroundiswet.从(“地面润湿〞作出“下过雨〞的推

测，但地湿其实不用然是下雨所致,for不可以够够换为because。)(3)Thegroundiswetbecauseithasrained.“(下雨〞是“地上润湿〞的直接原因。)前

后两个分句间有必然的因果关系时(有时很难区分是直接原因，还是推断性原因)，for与because能够互换使用。比方：(4)Icouldnotgo,for/becauseIwasill.我没能去，是由于我病了。(5)Hefeltnofear,for/becausehewasabraveboy他.没有害怕，由于他是个勇敢的男孩。Because/asbecause引导的是必然原因，as引导一般原因。必然原因是指某事发生必会以致另一件事实。一般原因语气还有其因果关系不是很显然。以下两个句子请体会Theflooriswet,becauseitrainedthismorning.Astheflooriswet,itmightrainthismorning.(地板湿也可能是其他原因，以此看，as引

导原因从句还有猜想的意味。)Because/for这两个词的意思很周边，平时是能够互换使用的。为了安全起见，最好用because引导从句，由于同because引导的从句对照，for引导的从句〔英文中称为for－clause〕的用法要碰到某些限制：1for引导的从句不可以够位于它所讲解的动词从前：Becauseitwaswethetookatax．i因为下雨，他叫了一辆出租车。〔这里不可以够用for。〕2for引导的从句不可以够位于not，but或任何连词此后：Hestole，notbecausehewantedthemoneybutbecausehelikedsteal．ing他偷东西，其实不是由于他想要钱，而是他有这种弊端。〔这里不可以够用for。〕3for引导的从句不可以够

用于答复以下问题：—Whydidyoudoit？—IdiditbecauseIwasangry．—你为何这么做？—由于我生气才这么做的。〔这里不可以够用for。〕4for引导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．ShewasangrybecausehehadspokeninFren．ch他讲法语。因

为他讲法语，她生气了。〔这里不可以够用for。〕但是能够说：Shewasangry，forshedidn’tknowFrench．她生气了，由于她不懂法语。〔这里用for是正确的，也可用because。〕2之所以有这些用法上的限制，其原因是for引导的从句不可以够直接说明某一特定动作发生的原因，而只好供应一些起帮助讲解作用的附加说明。例句如：Thedayswereshor，tforitwasnowDecember．天短了，此刻已经是12月了。Hetookthefoodeagerly，forhehaseatennothingsincedaw．n他狼吞虎咽地吃了起来，由于他从天亮就没吃过东西。1.HecanspeakEnglish_______Chinese.A.butB.alsoC.soD.and2.Physicsisnotsoeasy,_______Ilikeitverymuch.A.butB.orC.sinceD.because3.WillTomwaitforherathome______atthelibrary?
