北师大版初三英语第6讲：unit-3-语法篇(学生版)

Unit3语法篇____________________________________________________________________________________________________________________________________________________________________理解并掌握常见连词及表示原因连词的用法1.常见连词(and,but,or,so)的用法(1)and“和，而且，又”，表示并列关系。例如：Iwokeupandgotoutofbed.我醒了就起床了。(2)but“但是”表示转折关系。例如：IgotupearlybutIstillmissedthefirstbus.我起得很早，但仍然错过了早班车。(3)or“或者；否则”。例如：Hurryup,oryouwillbelate.快点儿，否则你就要迟到了。(4)so“所以”，表示因果关系。例如：Iheardsomenoiseoutside,soIwentoutoftheroomtoseewhy.我听见外面有些声音，所以走出房间去看看是怎么回事。2.because,since,as,for表示原因的区别because,since,as都是表示“原因”的从属连词，引导原因状语从句；而“for”也表示原因，引导的是并列句。语气由强至弱一次为：because,since,as,for。(1)because表示直接原因，它所指的原因一般是听话人所不知道的，语气最强。常用来回答why的提问，一般放在主句之后，也可以单独存在。例如：Whyareyoulate?你为什么迟到了？BecauseImissedtheearlybus.因为我错过了早班车。(2)since侧重主句，从句表示显然的或者已为人所知的理由，常译为“因为，既然”，语气比because稍弱，通常置于句首，表示含有一种勉强语气的原因。例如：Sinceeverybodyishere,let’sbegin.既然大家都在这里，我们开始吧。(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；比since语气弱，没有since正式，常译为“由于，鉴于”。从句说明原因，主句说明结果，主从句并重。例如：AsIwasnotready,theywentwithoutme.由于我没有准备好，他们没有带我去。(4)for表明附加或推断的理由，其后的分句不能放句首，语气最弱。例如：Itmushhaverainedlastnight,forthegroundiswet.昨晚一定下了雨，因为地面是湿的。3.其他常见连词(1)if如果，表示条件，引导条件状语从句。unless,除非，如果不=if…not。例如：Ifitdoesn’traintomorrow,wewillgotothepark.(前半句可改为Unlessitrainstomorrow)如果明天不下雨，我们就会去公园。(2)although虽然，尽管，引导让步状语从句。不与but连用。例如：Althoughnomanagreedwithhim,heheldonhisviews.尽管没人赞同他的观点，他还是坚持自己的看法。1.Tomwaslateforschool__________it’sraininghard.A.becauseof
