come,go等。*Iwasdoingmyhomeworkwhenthetelephonerang.我在做作业时电话铃响了。*CanyoulookaftermypetdogwhileI’maway?我离开的时间你能照看我的小狗吗？（4）since;自从……以来。该连词所连接的从句中的谓语动词通常是过去时，主句通常是一般现在时或现在完成时。It’sfiveyearssinceIstudiedEnglish.我学习英语已经五年了。IhavelivedinBeijingsinceIcametoChina.我来到中国后就住在北京。（5）assoonas:一……就……。该连词所在的主从句中，若主句是一般将来时，从句要用一般现在时表示将来的意义。I’llcallyouassoonasIgetthere..引导原因状语从句的连词：because,as,since,6等*Shedidn’tgothere,becauseshewasill..引导目的状语从句的连词so,sothat,inorderthat等*Hegotupearlysothathecangettheearlybus.4.引导结果状语从句的连词：so…that,such…that等（1）such修饰名词{a/an+adj.+n.+that从句adj+不可数名词/可数名词复数（2）so修饰形容词或副词So+adj./adv.+that从句（3）当名词由many,much,few或little修饰时不用such而用so,即：many/few复数名词+that从句*Heimuch/litc恰不可数名词%?alllikehim.=Heissocleverthatwealllikehim.*Healwaysaskssomanystrangequestions..|引导条件状语从句的连词：if“如果"；unless"除非……”*Ifitisfinetomorrow,we’llgotothepark.*We’llbelateunlesswehurryup..引导地点状语从句的连词：where;wherever等*Youcangowhereveryoulike.你可以去你想去的任何地方。.引导让步状语从句的连词有though,although,even,if,howeveir*Thoughitisraininghard,wemustgetthereontime..引导比较状语从句的连词：as,than,as...as,more…than等HecanranasfastasLiuXiang.HeisbetteratEnglishthanI.AmericanpeoplehavethesamewayofdressingasCanadianpeople.二、引导宾语从句的连词我很高兴你乐于帮助别人。that连接由陈述句转变成的宾语从可我很高兴你乐于帮助别人。*I’mgladthatyou’rereadytohelpothers.if,whether引导由一般疑问句转变而来的宾语从句If和whether引导宾语从句时，一般情况下可以互换，if在口语中用的较多，whether在书面语和正规场合下用的较多。但下列情况只用whether不用if。（1）与动词不定式连用时。*Idon’tknowwhethertogo.（2）在介词后作宾语时。*I’mworriedaboutwhethershecancomehereontime.（3）在主语从句，表语从句和同位语从句中。*Whetherwe’llgototheparkdependsontheweather.我们是否去公园里看天气。（4）与ornot连用时。*Idon’tknowwhethertogoornot.（5）在动词discuss后的宾语从句中。*We’rediscussingwhetherwe’llholdasportsmeeting.|who,whom,whatwhich,whose,when,where,why,how连接由特殊疑问词转变而来的宾语从句。注意：When既可引导宾语从句，又可引导状语从句。引导状语从句时要用一般现在时表达将来时。－Doyouknowwhenhewillarrivetomorrow?－I’llringyouupwhenhearrives.三、引导其他从句的连词that,if,whether和what等可引导主语从句，表语从句和定语从句。*Whattheyweardependsontheirlikesanddislikes.他们的穿着取决于他们的喜好。（主语从句）*Thequestioniswhetherwecangetthereontime.问题是我们能否按时到达。（表语从句）易混知识清单一、不能用同时出现在一个句子中的连词because（因为），so（所以）不能同时出现在一个句子里，只能用其一。*Becausehewastired,hecouldn’twalkthere.=Hewastired,sohecouldn’twalkthere.（al）though（虽然），but（但是）不能同时出现在一个句子里，只能用其一。但though和yet可以同时出现在一个句子里（yet作adv.用）。*Thoughhewastired,hestillworkedhard.=Hewastired,buthestillworkedhard.二、if的不同用法If有两个意思，当“是否”讲时，引导宾语从句，意同whether，从句的时态由事实决定；作“假如，如果”讲时，引导条件状语从句，此时若主句为将来时或祈使句时，从句用一般现在时。*Wedon’tknowifitwillraintomorrow.*Ifitrains,wewon’thaveasportsmeeting.我们不知道明天是否下雨。如果下雨，我们就不能开运动会了。三、and和or用于否定句中。.列举成分是主语，又在否定词之前，用and连接，而在否定词之后的列举成份用or构成完全否定。*Ican’tsingordance.*LucyandLilycan’tspeakChinese..在否定句中，如果所接的两部分都有否定词，那么用and而不用or连接。*Thereisnowaterandnoaironthemoon..在否定句中，without之后若有列举成分用and连接，构成完全否定；而在肯定句中，without之后的列举成分要用or连接才能构成完全否定。*Mancan’tlivewithoutairandwater.=Manwilldiewithoutairorwater.【EnhancingExercises】.用适当的并列连词填空。I’mateacher,heisateacher,too.Useyourhead,you'llfindagoodidea.Hefinishedhishomeworkquiteearly,didn'tdoitverywell.LilylikespianoLucydoesn't.Gotoseethedoctoratonce,yourcoldmaygetworse.Iaskedhimtocomehere,Imuststayathome.Theboywenttosleepsoon,hewastired.It'srainingoutside,Imuststayathome.9.Theoldteacherisverytired,shestillworksveryhard.10.heIaregoodatplayingfootball.11.ShecanwritespeakEnglishverywell.12.Youcanleave_todaytomorrow.13.you_heisn'tright.14.you_heisright.15.youyourfatherdrawswell.16.Youcanstayinthegardeninthereading-room.17.Theropeistoolongtooshort.18.Idon'tknowhim,doIknowwherehecomesfrom..用适当的从属连词填空。Mymothertoldusthemoonisround.Thetwinsweredrawingacartheteachercamein.IenteredtheroomMissGaowastalkingwithmyparents.Thebabydidn'tcryhismothercameback.IwenttobedIfinishedmyhomework.HehadstudiedEnglishforayearhecamehere.IhavelivedthereformorethantenyearsIleftthearmy.Shedidn'tgotherehewasill.itdoesn'train,we'llgotothepark.Heisoldhecan'twalkfast.Mr.Hanspeaksloudlyeveryonecanhearclearly.I'msorryyourwatchisbroken.Canyoutellmeyougothereornot?Iwonderyouwillgothere.hewasverytired,hewentonworkinghard.II.Choosethebestanswerfromthefourchoices()1.PleaselookafterthechildrenIamout.A.thoughB.sothatC.thatD.while()2.PleasespeakloudlyIcanhearalittlebetter.A.thoughB.sothatC.suchthatD.as()3.Ringmeupyoucometomyhouse.A.thoughB.asC.beforeD.than()4.MorepeoplecameIexpected.A.asifB.sothatC.sinceD.than()5.YoumustgoItoldyou.A.afterB.beforeC.whereD.as()6.YoumustdoItoldyou.A.afterB.beforeC.whereD.as()7.ClassOneislargeClassTwo.A.so...thatB.as...asC.such...thatD.so...as()8.Theywillbethankfulforyouhavedone.A.whatB.thatC.whichD.who()9.Idon'tknowIshouldchoose.A.whyB.whenC.whichD.what()10.IwillwritetoyouIgetthere.A.whileB.assoonasC.asD.since()11.heisold,hecanwalkveryfast.A.IfB.AlthoughC.SinceD.Because()12.We'llgotovisittheWallitrainstomorrow.A.sinceB.assoonasC.whenD.unless()13.Youmustgetupearlytomorrow,Iwillgotherealone.A.orB.andC.yetD.for()14.Itwasraininghard,,thepeasantswentonwiththeirwork.A.butB.andC.howeverD.although()15.DoyouknowJaneisgettingonwellwithherclassmates?A.whatB.howC.thatD.which()16.Heisnotonlyafootballplayer.A.butalsoplaysthepianoB.butthepianistC.butplaythepianoaswellD.butafamouspianist(
