theiropinions,____theyaredifferentfromyourown.A.untilB.evenifC.unlessD.asthoughABwhile是高频词，它既可引导时间状语从句，又可引导并列句，还可引导让步状语从句，表示“尽管”。evenif等于eventhough，表示“即使、尽管”。asthough等于asif，引导方式状语从句，表示“好像、似乎”。26\n问题2：1、Hetriedhisbesttosolvetheproblem,___difficultitwas.A.howeverB.nomatterC.whateverDalthough2、Theoldtowermustbesaved,______thecost.A．howeverB．whateverC．whicheverD．whereverABnomatterwh-与wh-ever的联系及区别：nomatterwh-只引导让步状语从句，此时与wh-ever通用。如:Nomatterwhen/Wheneverhecomesback,heshouldbeinvitedtotheparty.wh-ever又可引导名词性从句，Nomatterwh-不能。如：WhateverIcandoforyouwillbenothingbutpayingadebt.Whoevercanhelpuswillbewelcome27\n五、方式状语从句：由连词：as,asif,asthough引导：Theteachertoldthestudentstodoashedid.Leaveitasitis.Heheardanoise,asifsomeonewasbreathing.Isawthemanlookingabouthimasifhewishedtoimpressuponhismindeverything.28\nasif和asthough意义和用法大致一样，引导的从句多用虚拟语气，但也可用陈述语气。HetreatsmeasifIwerehisownson.Hewalkedasifheweredrunk.asif/asthough也可以引导一个分词短语、不定式短语或无动词短语，例如：Hestaredatmeasifseeingmeforfirsttime.他目不转睛地看着我，就像第一次看见我似的。Heclearedhisthroatasiftosaysomething.他清了清嗓子，像要说什么似的。Thewavesdashedontherocksasifinanger.波涛冲击着岩石，好像很愤怒。29\n六、目的状语从句：通常由that,sothat,inorderthat,so…that,lest,incase（以防、免得）等引导：Hegotupearlyinorderthathecouldcatchtheearlybus.Shemarriedhimsothatshemighttendandcomforthim.Iexplainedagainandagainincaseheshouldmisunderstandme.30\n七、地点状语从句：通常由连词where和wherever引导。如：Gobackwhereyoucamefrom.Whereveryougo,youmustwritetoyourparents.Wherethereisawill,thereisaway.Wherethereistoomuch,thepoisonandwastemaydogreatharmtothethingsaroundus.31\n与定语从句有本质区别Makeamarkwhereyouhaveanydoubts.Makeamarkattheplacewhereyouhaveanydoubts.(一个说明动作发生的地点，一个修饰说明theplace)32\n八结果状语从句结果状语从句常由so…that或such…that引导，掌握这两个句型，首先要了解so和such与其后的词的搭配规律。33\n比较：so和suchsuch是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。so…that与such…that之间的转换既为so与such之间的转换。Theboyissoyoungthathecan'tgotoschool.Heissuchayoungboythathecan'tgotoschool34\nSothat---因而，以便，为了有时so可以省去CanyoumoveyourluggagealittlebitawaysothatIcanputmineintheoverheadbintoo.Speaklouderpleasesothatthepeopleatthebackcanhearyou.35\n9.比较状语从句引导比较状语从句的连词有：As…as…,notso(as)…as…,.…than…,themore…themore...36\nAs…as…---像……一样Ifyoudon’twanttomisstheflight,youneedtobeattheairportasearlyaspossible.Mygrandmatoldmethathereyesightwasasgoodas10yearsbefore.37\nNotso(as)…as…---不像……ThejobisnotsodifficultasIthoughtitwouldbe.Theflightwasnotso/asharmfulasthecaptainpredicted.38\n…than…---比……怎么样，用于事物间的比较，more后面用形容词或副词Peoplebelievethatbeingastewardessisbetterthanmostoftheotherjobs.IpersonallythinkthattheAmericanmoviesaremoreinterestingthanChineseones39\nThemore…,themore---越……越Themorehelistenedtothatsong,thelessheenjoyedit.Themorethingsamanisashamedof,themorerespectableheis.40\n1.______youdecidetotakeup,youshouldtrytomakeitasuccess.A.IfB.WheneverC.UnlessD.Whatever41\n2.Itisfoolishtotakeataxi_______youcaneasilywalktothestation.A.beforeB.thatC.unlessD.when42\n3.I’llacceptanyjob,_____Idon’thavetogetupearly.A.eventhoughB.thoughC.incaseD.aslongas43\n4.___________problemsyouhave,youcanalwayscometomeforhelp.A.WhatB.WhateverC.WhicheverD.Which44\n5.______muchadviceIgavehim,hedidexactlywhathewantedtodo.A.HowB.WhateverC.HoweverD.Nomatter45\n7.Ifweworkwithastrongwill,wecanovercomeanydifficulty,_______greatitis.A.whatB.howC.howeverD.whatever46\n8.Ihurried_____Iwouldn’tbelateforclass.A.sinceB.sothatC.asifD.unless47\n9.Johnplaysfootball_____,ifnotbetterthan,David.A.aswellB.aswellasC.sowellD.sowellas48\n10.--Whatwasthepartylike?--Wonderful.It’syears____Ienjoyedmyselfsomuch.A.afterB.whenC.beforeD.since49\n11.Don’tchangeyourmind,______happenstoyou.A.whichB.whatC.whicheverD.whatever50\n12.___________hecomes,wewon’tbeabletogo.A.WithoutB.UnlessC.ExceptD.Even51\n13.Nobodybelievedhim____________whathesaid.A.eventhoughB.evenifC.nomatterD.because52\n15.Takeyourumbrellawithyou____________itrains.A.ifB.asifC.incaseD.aslongas53\n16.Nosooner_______enteredtheoffice_______Iheardthetelephoneringing.A.hadI,whenB.Ihad,thanC.hadI,thanD.Ihad,when54\n17.Ihadhardlyarrived_____hestartedcryingtogohome.A.asB.forC.whenD.until55\n18.Itwon’tbelong________youregretwhatyousaid.A.sinceB.whenC.beforeD.till56\n19.Thenewsecretaryissupposedtoreporttothemanagerassoonasshe______.A.willarriveB.arrivesC.isgoingtoarriveD.isarriving57\n20.______thedaywenton,theweathergotworse.A.WithB.SinceC.WhileD.As58\n状语从句验收题1.Whatwasthepartylike?Wonderful.It’syears________Ienjoyedmyselfsomuch.AafterBwhenCbeforeDsince2.________thedaywenton,theweathergotworse.AWithBSinceCWhileDAs3.Therooffell____________hehadtimetodashintotheroomtosavehisbaby.AafterBasCbeforeDuntil4.Iwasabouttoleave__________hecameforavisit.AwhenBwhileCasDuntil5.Cometoseeus_________youcan.AbeforeBafterCuntilDwhenever6.Hefellasleep________hewaslisteningtotheradio.AassoonasBsinceCwheneverDwhile7.Wedowanttobuysomethingnow_________pricesgoup.AeversinceBuntilCbeforeDwhenever8.Itwon’tbelong_______wemeetagain.AbeforeBwhenCsinceDas9.Pleasewritedownhistelephonenumber_______youforgetit.AafterBwhenCuntilD.before1,C;2.D;3,C;4,A;5,D;6,D;7,C;8,A;9,D59\n10.Howtimeflies!Threemonthshaspassed______weknowi
