初中英語語法連詞專項練習

初中英語語法之連詞專項練習初中英語語法之連詞專項練習初中英語語法之連詞專項練習初中英語語法連詞詞專項習題[Because,since,as,for]because,as,for,since這幾個詞都是表示“原因〞的連詞，語氣由強至弱依次為：because

→since→as→for;其中because,since,as均為隸屬連詞，引導(dǎo)原因狀語從句；而for是并列連詞，引導(dǎo)并列句。1.because表示直接原因，它所指的原因平時是聽話人所不知道的，其語氣最強。常用往返答why的發(fā)問，一般放于主句以后，也能夠獨自存在。例

如：(1)Istayedathomebecauseitrained因.為下雨我呆在家里。(2)BecauseLinglingwasill,shedidn'tcometoschool.玲玲因病，沒有上學(xué)。(3)—

Whyissheabsent?她為何缺席？—Becausesheissick因.為她病了。其他，在重申句型中，只好用because。比方：(4)ItwasbecauseImissedtheearlybusthatIwaslateforschoo我l.上學(xué)遲到是由于我沒有追上早班汽車。2.since重視主句，從句表示顯然的或已為人所知的原因，常譯為“由于〞、“既然〞，

語氣比because稍弱，平時置于句首，表示一種含有勉強語氣的原因。比方：(1)Sinceheasksyou,you'lltellhimwhy.他既然問你，那就告訴他為何

吧。(2)Sinceeveryoneishere,let'sstart既.然大家都到齊了，我們就出發(fā)吧！(3)SinceIunderstoodverylittleJapanese,Icouldn'tfollowtheconversation.我日語懂得不多，所以聽不懂對話。3.as是常用詞，它表示的“原因〞是雙方的事實或不問可知的原因，也許原因不

是很重要，含義與since相同，但語氣更弱，沒有since正式，常譯為“由于，鑒于〞。從句說明原因，主句說明結(jié)果，主從并重。比方：(1)Wealllikeherassheiskind.我們都喜歡她，由于她和藹。(2)AsIhadacold,Iwasabsentfromschool.由于我感冒了，所以沒去上課。(3)AsXiaowangwasnotready,wewentwithouthim.由于小王沒有準備好，我們只好不帶他去了。4.for用作連詞時，與because相似，但它所表示的原因經(jīng)常供應(yīng)上文未交待過的情況。

for不表示直接原因，說明附加或推斷的原因，所以for被看作等立連詞，它所引導(dǎo)的分句只好放在句子后部(或獨自成為一個句子)，并且前后兩個分句間的邏輯關(guān)系不用然是因果關(guān)系，此間用逗號分開，且for不可以置于句首，for的這一用法常用在書面語中，較正式。比方：1(1)Thedaysareshort,foritisnowDecember.白日短了，由于此刻已經(jīng)是十二月份。(2)Itmusthaverained,forthegroundiswet.從(“地面潤濕〞作出“下過雨〞的推

測，但地濕其實不用然是下雨所致,for不可以夠夠換為because。)(3)Thegroundiswetbecauseithasrained.“(下雨〞是“地上潤濕〞的直接原因。)前

后兩個分句間有必然的因果關(guān)系時(有時很難區(qū)分是直接原因，還是推斷性原因)，for與because能夠互換使用。比方：(4)Icouldnotgo,for/becauseIwasill.我沒能去，是由于我病了。(5)Hefeltnofear,for/becausehewasabraveboy他.沒有害怕，由于他是個勇敢的男孩。Because/asbecause引導(dǎo)的是必然原因，as引導(dǎo)一般原因。必然原因是指某事發(fā)生必會以致另一件事實。一般原因語氣還有其因果關(guān)系不是很顯然。以下兩個句子請體會Theflooriswet,becauseitrainedthismorning.Astheflooriswet,itmightrainthismorning.(地板濕也可能是其他原因，以此看，as引

導(dǎo)原因從句還有猜想的意味。)Because/for這兩個詞的意思很周邊，平時是能夠互換使用的。為了安全起見，最好用because引導(dǎo)從句，由于同because引導(dǎo)的從句對照，for引導(dǎo)的從句〔英文中稱為for－clause〕的用法要碰到某些限制：1for引導(dǎo)的從句不可以夠位于它所講解的動詞從前：Becauseitwaswethetookatax．i因為下雨，他叫了一輛出租車?！策@里不可以夠用for?！?for引導(dǎo)的從句不可以夠位于not，but或任何連詞此后：Hestole，notbecausehewantedthemoneybutbecausehelikedsteal．ing他偷東西，其實不是由于他想要錢，而是他有這種弊端?！策@里不可以夠用for。〕3for引導(dǎo)的從句不可以夠

用于答復(fù)以下問題：—Whydidyoudoit？—IdiditbecauseIwasangry．—你為何這么做？—由于我生氣才這么做的?！策@里不可以夠用for?！?for引導(dǎo)的從句不可以單單用來復(fù)述已講過的話，而一定包含新的內(nèi)

容：HespokeinFrench．ShewasangrybecausehehadspokeninFren．ch他講法語。因

為他講法語，她生氣了?！策@里不可以夠用for?！车悄軌蛘f：Shewasangry，forshedidn’tknowFrench．她生氣了，由于她不懂法語?！策@里用for是正確的，也可用because?！?之所以有這些用法上的限制，其原因是for引導(dǎo)的從句不可以夠直接說明某一特定動作發(fā)生的原因，而只好供應(yīng)一些起幫助講解作用的附加說明。例句如：Thedayswereshor，tforitwasnowDecember．天短了，此刻已經(jīng)是12月了。Hetookthefoodeagerly，forhehaseatennothingsincedaw．n他狼吞虎咽地吃了起來，由于他從天亮就沒吃過東西。1.HecanspeakEnglish_______Chinese.A.butB.alsoC.soD.and2.Physicsisnotsoeasy,_______Ilikeitverymuch.A.butB.orC.sinceD.because3.WillTomwaitforherathome______atthelibrary?
