1、-初中英语语法之连词专项练习-第 8 页初中英语语法连词词专项习题 Because,since,as,forbecause,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：becausesinceasfor;其中because,since,as均为从属连词，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，它所指的原因通常是听话人所不知道的，其语气最强。常用来回答why的提问，一般放于主句之后，也可以单独存在。例如：(1)Istayedathomebecauseitrained.因为下雨我呆在家里。(2)BecauseLingling

2、wasill,shedidntcometoschool.玲玲因病，没有上学。(3)Whyissheabsent?她为什么缺席？Becausesheissick.因为她病了。此外，在强调句型中，只能用because。例如：(4)ItwasbecauseImissedtheearlybusthatIwaslateforschool.我上学迟到是因为我没有赶上早班汽车。2.since侧重主句，从句表示显然的或已为人所知的理由，常译为“因为”、“既然”，语气比because稍弱，通常置于句首，表示一种含有勉强语气的原因。例如：(1)Sinceheasksyou,youlltellhimwhy.他既然问

3、你，那就告诉他为什么吧。(2)Sinceeveryoneishere,letsstart.既然大家都到齐了，我们就出发吧！(3)SinceIunderstoodverylittleJapanese,Icouldntfollowtheconversation.我日语懂得不多，因而听不懂对话。3.as是常用词，它表示的“原因”是双方已知的事实或显而易见的原因，或者理由不是很重要，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。例如：(1)Wealllikeherassheiskind.我们都喜欢她，因为她善良。(2)AsIhadac

4、old,Iwasabsentfromschool.因为我感冒了，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，但它所表示的原因往往提供上文未交待过的情况。for不表示直接原因，表明附加或推断的理由，因此for被看作等立连词，它所引导的分句只能放在句子后部(或单独成为一个句子)，并且前后两个分句间的逻辑关系不一定是因果关系，其间用逗号隔开，且for不可置于句首，for的这一用法常用在书面语中，较正式。例如：(1)Thedaysareshort,foritisno

5、wDecember.白天短了，因为现在已是十二月份。(2)Itmusthaverained,forthegroundiswet.(从“地面潮湿”作出“下过雨”的推测，但地湿并不一定是下雨所致,for不可以换为because。)(3)Thegroundiswetbecauseithasrained.(“下雨”是“地上潮湿”的直接原因。)前后两个分句间有一定的因果关系时(有时很难区分是直接原因，还是推测性原因)，for与because可以互换使用。例如：(4)Icouldnotgo,for/becauseIwasill.我没能去，是因为我病了。(5)Hefeltnofear,for/because

6、hewasabraveboy.他没有害怕，因为他是个勇敢的男孩。lBecause/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导致另一件事实。一般原因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.(地板湿也可能是其他原因，以此看，as引导原因从句还有猜测的意味。)lBecause/for这两个词的意思很相近，通常是可以互换使用的。为了安全起见，最好用because引导从句，因为同because引导的从

7、句相比，for引导的从句（英文中称为forclause）的用法要受到某些限制：1for引导的从句不能位于它所解释的动词之前：Becauseitwaswethetookataxi因为下雨，他叫了一辆出租车。（这里不能用for。）2for引导的从句不能位于not，but或任何连词之后：Hestole，notbecausehewantedthemoneybutbecausehelikedstealing他偷东西，并不是因为他想要钱，而是他有这种毛病。（这里不能用for。）3for引导的从句不能用于回答问题：Whydidyoudoit？IdiditbecauseIwasangry你为什么这么做？因为我

8、生气才这么做的。（这里不能用for。）4for引导的从句不能单单用来复述已讲过的话，而必须包括新的内容：HespokeinFrenchShewasangrybecausehehadspokeninFrench他讲法语。因为他讲法语，她生气了。（这里不能用for。）但是可以说：Shewasangry，forshedidntknowFrench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定，其理由是for引导的从句不能直接说明某一特定动作发生的原因，而只能提供一些起帮助解释作用的附加说明。例句如：Thedayswereshort，foritwas

9、nowDecember天短了，现在已是12月了。Hetookthefoodeagerly，forhehaseatennothingsincedawn他狼吞虎咽地吃了起来，因为他从天亮就没吃过东西。1. He can speak English_ Chinese.A. but B. also C. so D. and2.
