Unit3語法篇____________________________________________________________________________________________________________________________________________________________________理解并掌握常見連詞及表示原因連詞的用法1.常見連詞(and,but,or,so)的用法(1)and“和，而且，又”，表示并列關(guān)系。例如：Iwokeupandgotoutofbed.我醒了就起床了。(2)but“但是”表示轉(zhuǎn)折關(guān)系。例如：IgotupearlybutIstillmissedthefirstbus.我起得很早，但仍然錯過了早班車。(3)or“或者；否則”。例如：Hurryup,oryouwillbelate.快點兒，否則你就要遲到了。(4)so“所以”，表示因果關(guān)系。例如：Iheardsomenoiseoutside,soIwentoutoftheroomtoseewhy.我聽見外面有些聲音，所以走出房間去看看是怎么回事。2.because,since,as,for表示原因的區(qū)別because,since,as都是表示“原因”的從屬連詞，引導(dǎo)原因狀語從句；而“for”也表示原因，引導(dǎo)的是并列句。語氣由強至弱一次為：because,since,as,for。(1)because表示直接原因，它所指的原因一般是聽話人所不知道的，語氣最強。常用來回答why的提問，一般放在主句之后，也可以單獨存在。例如：Whyareyoulate?你為什么遲到了？BecauseImissedtheearlybus.因為我錯過了早班車。(2)since側(cè)重主句，從句表示顯然的或者已為人所知的理由，常譯為“因為，既然”，語氣比because稍弱，通常置于句首，表示含有一種勉強語氣的原因。例如：Sinceeverybodyishere,let’sbegin.既然大家都在這里，我們開始吧。(3)as是常用詞，它表示的原因是雙方已知的事實或顯而易見的原因，或者理由不是很重要；比since語氣弱，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，主從句并重。例如：AsIwasnotready,theywentwithoutme.由于我沒有準(zhǔn)備好，他們沒有帶我去。(4)for表明附加或推斷的理由，其后的分句不能放句首，語氣最弱。例如：Itmushhaverainedlastnight,forthegroundiswet.昨晚一定下了雨，因為地面是濕的。3.其他常見連詞(1)if如果，表示條件，引導(dǎo)條件狀語從句。unless,除非，如果不=if…not。例如：Ifitdoesn’traintomorrow,wewillgotothepark.(前半句可改為Unlessitrainstomorrow)如果明天不下雨，我們就會去公園。(2)although雖然，盡管，引導(dǎo)讓步狀語從句。不與but連用。例如：Althoughnomanagreedwithhim,heheldonhisviews.盡管沒人贊同他的觀點，他還是堅持自己的看法。1.Tomwaslateforschool__________it’sraininghard.A.becauseof
