语法总结6连词1.定义 连词是一种虚词，不能单独充当句子成分，在句中只起连接作用。连词分为并列连词和从属连词两种。并列连词是连接彼此并列关系的词。从属连词是用来引导从句的词。2.并列连词(1)并列关系 and“和” Hegotupandlefttheroom.both...and...“…和…都” Ilikebothsportsandmusic.neither...nor...“既不…也不…”NeitherTomnoryouareadriver.notonly...butalso...“不但…而且..."ShelearnsnotonlyEnglishbutalsoJapanese.转折关系 but“但是” Sheistiredbuthappy.yet“然而” Hehasagoodjob,yetheneverhasmoney.while“然而” Ilikespringwhilemybrotherlikeswinter.因果关系 so“所以” Igotuplatetoday,soIwaslateforschool.for“所以” Iwenttosleepsoon,forIwasverytired.选择关系 or“或者” Wouldyoulikecoffeeortea?either...or...“要么…要么…” Eitheryouorsheiswrong.3.从属连词引导名词性从句连接主语从句、表语从句与宾语从句的连词只有三个，即that,if,whether.Askherifshewillcomewithme.Thereasonisthatsheneverwastedhertime.Idon'tknowwhetherhehadpassedtheexam.3.引导状语从句(1).连接时间状语从句 since,until,after,before.when,while,assoonas,whenever.I'lltellyouassoonasIknow.(2)连接地点状语从句 where,wherever.IfoundmybookswhereIhadleftthem.(3)连接让步状语从句 although,though,evenif.however.Althoughshewastired,shekeptonworking.(4)连接原因状语从句 as,because,since,nowthat.Hewasabsentbecausehewasill.(5) 连接目的状语从句 that.sothat,inorderthat.Heraisedhisvoicesothatwecouldhearhim.(6)连接条件状语从句 if,unless,once,incase.You'llmissthetrainunlessyouhurryup.连接结果状语从句 so...that,such...that.Hecamesolatethathemissedtheclass.(8)连接比较状语从句 as...as...,notso...as...,less(more)...than,the...the...ThisismorethanIcanaccept.(9)连接方式状语从句 as,asifItlooksasifitwasgoingtorain.4.常用从属连词的辨析(1).when,while,as when引导的从句,谓语既可以是延续性动词,也可以是非延续性动词,主从句动作可同时发生也可先后发生。IwanttobeateacherwhenIgrowup.while引导的从句,谓语只能是延续性动词,强调某一段时间内主从句动作同时发生，常对同类的动作进行对比。Whilewewerewaitingforabus,itwasrainingheavily.as作从属连词引导时间状语时强调主句和从句的动作并行发生，不指先后，尤指短动作或事件同时发生。AsIlooked,someonecamenear.(2)because,as,for because意为“因为”，表示造成某种情况的直接原因,语气最强,常用来回答由why构成的问句。Whydoyouliketalkshows?-Becausetheyareinteresting. as表示原因时，引出的理由在说话人看来很明显，不需要用because加以强调。Assheisastudent,shecan'tdriveacar. for补充说明理由，不用于句首，用逗号与前面的分句隔开，且for分句不能用来回答why问句。Ididn'tgooutyesterday,fortheweatherwasverybad.初中语法连词练习用最恰当的连词填空1.It'sanoldcar,itworkswell.2.IhatetravellingbyairIusuallyhavetowaitforhoursbeforetheplanetakesoff.3.______youdrive,youmustn'tdrinkatall.4.Tonyisonlyfouryearsold,hedrawsverywell.5.Don'tcryanymore.Ican'thelpyou____youtellmewhat'swrong!6._____sheisonly10,shehassetupherownwebsite7.smiletotheworld,theworldwillsmilebacktoyou.8.Ididn'tknowit_____youtoldme.9.Mybrotherlikesfruitalotandheeatsitthree_____fourtimesaweek.10.You'dbetterlookupthenewwordinadictionary_____youdon'tknowit.二、单项选择(60分)()1.OurEnglishteacherisniceandpatient____sheisverystrictwithus.A.ifB.as C.unless D.though ()2.Washyourhandsbeforemeals,___youmaygetill.A.andB.but C.or D.so ()3.Itwasgreatintheend______wehadaterribletimeinthebeginning.A.if B.unless C.when D.although ()4.Vivianwilltakeherdaughtertotheamusementparkshegetsthetickets.A.if B.until C.although D.unless ()5.-Excuseme.Whereisthenearesthotel?-Justgodownthisroadyouseealibrary.It'sacrossfromit.A.untilB.becauseC.howeverD.though()6.WewillneverseeKobeplayingbasketballgame,wewillalways rememberhim.
