As引導(dǎo)的讓步狀語(yǔ)從句必須倒裝（though和as意思相同，不過(guò)though引導(dǎo)讓步狀語(yǔ)從句可倒裝也可以不倒裝），歸納為以下五種句型：1、名詞+as/though+主語(yǔ)+動(dòng)詞

Kingashewas，hewasunhappy.他雖是國(guó)王，但他并不幸福。Childasheis，heknowstohelpother.他雖是個(gè)孩子，卻知道幫助別人。

【說(shuō)明】其中的動(dòng)詞通常為連系動(dòng)詞，也就是說(shuō)位于句首的名詞是其后連系動(dòng)詞的表語(yǔ)。另外，要特別注意位于句首的名詞前習(xí)慣上不用冠詞，即使其前有形容詞修飾也不用冠詞。比較：Boyas［though］heis，helikestoplaywithgirls.=Thoughheisaboy，helikestoplaywithgirls.他雖是男孩，卻喜歡與女孩子玩。Strongmanas［though］heis，GeneralBothahasbeenseverelyputtothetestduringthepastfewweeks.=Thoughheisastrongman，GeneralBothahasbeenseverelyputtothetestduringthepastfewweeks.波賽將軍雖然堅(jiān)強(qiáng)，但在過(guò)去的數(shù)周里也受到了嚴(yán)峻的考驗(yàn)。2、形容詞+as/though+主語(yǔ)+動(dòng)詞

Successfulasheis，heisnotproud.他雖然成功，但不驕傲。Improbableasitseems，it’strue.雖然看起來(lái)不太可能，但卻是真的。Stupidasitsounds，IwassoinlovewithherthatIbelievedher.盡管聽(tīng)起來(lái)很愚蠢，我是如此愛(ài)她竟然相信了她的話。Patientashewas，hedidn’tlikewaitingthatlong.他雖說(shuō)有耐心，也不愿等這么長(zhǎng)。Beautifulthoughthenecklacewas，wethoughtitwasover-priced.那條項(xiàng)鏈雖然很漂亮，我們認(rèn)為價(jià)錢(qián)太高。【說(shuō)明】其中的動(dòng)詞也通常為連系動(dòng)詞，也就是說(shuō)位于句首的形容詞是其后連系動(dòng)詞的表語(yǔ)。3、副詞+as/though+主語(yǔ)+動(dòng)詞MuchasIlikeParis，Icouldn’tlivethere.盡管我喜歡巴黎，但我不能住在那里。Hardthoughtheytried，theycouldn’tmakeherchangehermind.盡管他們做了很大努力，卻沒(méi)法讓她改變主意。Fastasyouread，youcan’tfinishthebookintwodays.盡管你讀得很快，你總不能在兩天之內(nèi)就讀完這本書(shū)。Hewasunabletomakemuchprogress，hardashetried.盡管他做了努力，卻未能取得很大進(jìn)步?！菊f(shuō)明】有的詞典將muchas作為習(xí)語(yǔ)看待，認(rèn)為它是一個(gè)用以引導(dǎo)讓步狀語(yǔ)從句的復(fù)合連詞。再如：MuchasIadmirehimasawriter，Idonotlikehimasaman.他作為一名作家我很佩服他，但我卻不喜歡他這個(gè)人。MuchasIlikeyou，Icouldn’tlivewithyou.我盡管很喜歡你，卻不能和你在一起生活。4、動(dòng)詞原形+as/though+主語(yǔ)+動(dòng)詞Objectasyoumay，I’llgo.縱使你反對(duì)，我也要去。Tryashemight，hecouldn’tsolvetheproblem.盡管他想方設(shè)法，卻未解決這個(gè)問(wèn)題。Searchastheywould，theywouldfindnobodyinthehouse.無(wú)論怎樣搜查，他們?cè)诜孔永锶匀粵](méi)有找到一個(gè)人。Dislikehimaswemay，wemustacknowledgehisgreatness.盡管我們不喜歡他，但必須承認(rèn)他的偉大。LosemoneyasIdid，wegotalotofexperience.錢(qián)雖然丟了，我們卻得到了許多經(jīng)驗(yàn)。Failintheelectionashedid，hebecamefamousforhisfieryspeechagainstslavery.盡管落選了，但他卻以其反對(duì)奴隸制的激烈演說(shuō)而出了名?！菊f(shuō)明】主語(yǔ)后的動(dòng)詞通常為may，might，would，did等情態(tài)動(dòng)詞或助動(dòng)詞(若表示情態(tài)意義，則選用情態(tài)動(dòng)詞；若陳述事實(shí)，則用did，do等助動(dòng)詞)。5、分詞+as/though+主語(yǔ)+動(dòng)詞Raininghardasitis，I’mgoingoutforawalk.雖然正在下著大雨，我還是要出去散步。Surroundedaswewerebytheenemy，wemanagedtomarchforward.雖然我們被敵人包圍著，但我們還是設(shè)法前進(jìn)了。Munchingtheappleashewas，hehadgotaneyeforallJohn’smovements.他盡管在一個(gè)勁地嚼著蘋(píng)果，但仍警惕著約翰的一舉一動(dòng)。6、補(bǔ)充說(shuō)明1）這類倒裝的讓步狀語(yǔ)從句可用as，though來(lái)引導(dǎo)，不能用although來(lái)引導(dǎo)；但是，未倒裝的讓步狀語(yǔ)從句卻可用though，although來(lái)引導(dǎo)，而不能用as來(lái)引導(dǎo)。也就是說(shuō)，although引導(dǎo)讓步狀語(yǔ)從句時(shí)不能倒裝，as引導(dǎo)讓步狀語(yǔ)從句時(shí)必須倒裝，而though引導(dǎo)讓步狀語(yǔ)從句時(shí)可以倒裝也可以不倒裝。如：雖然很晚了，但我們還是繼續(xù)工作。正：Lateas［though］itwas，westillwentonworking.正：Thoughitwaslate，westillwentonworking.誤：Latealthoughitwas，westillwentonworking.誤：Asitwaslate，westillwentonworking.2）上面提到的倒裝結(jié)構(gòu)有時(shí)也可用來(lái)表示原因，區(qū)別的辦法主要看句子的內(nèi)容：讓步從句的內(nèi)容大多數(shù)與主句在意義上相反，而原因從句則與主句之間有因果關(guān)系。比較：Tiredashewas，hesatuplatestudyingatnight.昨晚他雖然很疲倦了，但還是學(xué)習(xí)到很晚才睡。(表讓步)Tiredashewas，hewenttobedearly.因?yàn)楹芾?，所以他睡得很早?表原因)Youngashewas，hewasequaltothetask.他雖年輕，卻能勝任這項(xiàng)工作。(表讓步)Youngashewas，hewasnotequaltothetask.他因?yàn)槟贻p，所以不能勝任這項(xiàng)工作。(表原因)3）在美國(guó)英語(yǔ)中，人們通常用as...as引導(dǎo)讓步狀語(yǔ)從句。如：Coldasitwas，wewentout.=Ascoldasitwas，wewentout.盡管天氣冷，我們還是出去了。Successfulasheis，heisnotproud.=Assuccessfulasheis，heisnotproud.他雖成功了，但不驕傲。

as引導(dǎo)時(shí)間狀語(yǔ)從句as引導(dǎo)的時(shí)間狀語(yǔ)從句,可以表達(dá)“正當(dāng)……”，“一邊……一邊……”，“隨著……”等意思。1.表示某事一發(fā)生，另一事立即發(fā)生。Asthesunrose,thefogdisappeared.2.表示在某事發(fā)生的過(guò)程中，另一事發(fā)生。Justashewasspeakingtherewasaloudexplosion3.表示兩個(gè)動(dòng)作同時(shí)發(fā)生。Helensangasongasshewashed.表示“隨著…..”.常指一個(gè)行為是另一個(gè)行為的結(jié)果，或一種狀態(tài)隨另一種狀態(tài)變化。句中的動(dòng)詞多表示狀態(tài)的發(fā)展變化。Asshegrewolder,shebecamemorebeautiful.as引導(dǎo)原因狀語(yǔ)從句as引導(dǎo)的原因狀語(yǔ)從句一般比because語(yǔ)氣輕，多表示不談自明的原因。Ashewasnotwell,Idecidedtogowithouthim.as引導(dǎo)方式狀語(yǔ)從句、as引導(dǎo)的方式狀語(yǔ)從句as一般指“按照、正如”之意，asif意為“好像”。a.WemustdoasthePartytellsus.b.Leavethethingsastheyare.c.Mostplantsneedsunlightjustastheyneedwater.d.Itsoundsasifitisraining.e.Aswateristofish,soairistoman.As引導(dǎo)比較狀語(yǔ)從句:asas,notasasa.Theyjumpedupanddownashardastheycould.b.ThejobisnotsodifficultasIthoughtitwouldbe.六、as引導(dǎo)定語(yǔ)從句

as的用法:(as引導(dǎo)定語(yǔ)從句,在定語(yǔ)從句中作主語(yǔ)、賓語(yǔ)、表語(yǔ))

(一)如為限制性的，多用于thesame…as;thesameas；such…as…;asmany/muchas；so…as等結(jié)構(gòu)中。如：1.Ihavethesamebookasyou(have).我有一本和你的一樣的書(shū)。

Herattitudetohimwasquitethesameasithadalwaysbeen.(關(guān)系代詞as和指示代詞same連用,在從句中用作表語(yǔ),先行詞是same.)

2.Whydidn'tyoumentionthatinfaceofthepolicejustnow?Ithoughtitwassuchaminordetailaswashardlyworthmentioning.

Wewillonlydiscusssuchproblemsashavesomethingtodowithourowninterests.Don'tdosuchthingsasyouarenotsureabout.Thereisnosuchplaceasyoudreamofinallthisworld.比較：Iliveinthesamehousethatheusedtolivein.

I'mwearingthesameshirtasyouworeyesterday.比較：Hereissobigastoneasnoonecanlift.（定語(yǔ)從句）

Hereissobigastonethatnoonecanliftit.（結(jié)果狀語(yǔ)從句）

(二)如為非限制性的，多單獨(dú)引導(dǎo)一個(gè)定語(yǔ)從句，這種定語(yǔ)從句可置于句首，句中或句尾，譯為"正如，這一點(diǎn)"。（動(dòng)詞常為know,see,expect,pointout,etc.）1.Asweallknow,smokingisharmfultoone'shealth.(as作賓語(yǔ))=Asisknowntoall,smokingisharmfultoone'shealth.（as作主語(yǔ)）=It'sknowntoallthatsmokingisharmfultoone'shealth.或:Smokingisharmfultoone'shealth,asweallknow.（as作賓語(yǔ)）或:Smoking,asweallknow,isharmfultoone'health.2.Hewasaforeigner,asIknewfromhisaccent.

(賓語(yǔ),先行詞是前面整個(gè)句子)當(dāng)先行詞被thesame所修飾時(shí)，關(guān)系詞既可以用as，也可以用that。在表示具體事物時(shí)，有時(shí)兩者有一定的區(qū)別。一般說(shuō)來(lái)，表示同一種類多用as，表示同一事物多用that。如：ThisisthesameinstrumentthatIusedyesterday.這就是我昨天用過(guò)的那臺(tái)儀器。ThisisthesameinstrumentasIusedyesterday.這臺(tái)儀器跟我昨天用過(guò)的那臺(tái)一樣。在抽象概念上，同種類和同一事物是沒(méi)有絕對(duì)區(qū)別的，所以兩個(gè)詞可換用：Ihavethesameopinionas/thatyouhave.這里要注意的是：（1）使用as時(shí)，它引導(dǎo)的定語(yǔ)從句中的動(dòng)詞可以省略，但使用that時(shí)，定語(yǔ)從句中的動(dòng)詞不可省略。如：Womenreceivedthesamepayasmen.Womenreceivedthesamepaythatmenreceived.(2)在“thesame…that”結(jié)構(gòu)中，that只是用來(lái)加強(qiáng)語(yǔ)氣，強(qiáng)調(diào)“相同”。that可以省去而不改變句子原意，甚至連名詞前的same也可以省去。如：ThisisthesameinstrumentthatIusedyesterday.=ThisisthesameinstrumentIusedyesterday.=ThisistheinstrumentIusedyesterday.但在“thesame…as”結(jié)構(gòu)中，same和as都不能省略。(3)當(dāng)“thesame…that”結(jié)構(gòu)中的that作為關(guān)系副詞用時(shí)，不可以直接與as互換。如：HelivesinthesamebuildingthatIlive.=Helivesinthesamebuildingas/thatIlivein.Shallwemeetatthesameplacethatwelastmet?=Shallwemeetatthesameplacethat/aswelastmetat?7.當(dāng)先行詞前有such,so,as時(shí)，關(guān)系詞應(yīng)當(dāng)用as。如：Awisemanseldomtalksaboutsuchthingsashedoesn’tunderstand.HespokeinsucheasyEnglishaseverybodycouldunderstand.Atthistimeoftheday,allbusesandtrolleyshavetocarryasmanypassengersastheycan.Itissoeasyabookaseveryschoolboycanread.Let’sdiscusssuchthingsaswecantalkoffreely.另需注意：ThisbookiswritteninsucheasyEnglishasbeginnerscanunderstand.（定語(yǔ)從句）ThisbookiswritteninsucheasyEnglishthatbeginnerscanunderstand.（結(jié)果狀語(yǔ)從句）課堂練習(xí)1.Shesang______sheworked.A.AsB.sinceC.AssoonasD.While2.Smart______heis,hedoesn’tstudyhard.A.althoughB.sinceC.AsD.While3.Youmusttrytodo______Idid.A.whatB.asC.thatD.while4.Shedoesn’tdoherworkascarefully______I.A.withB.sinceC.asD.While5.______shewaslateforclass,shehadtosaysorry.A.ForB.SinceC.AsD.While6.______thedaywenton,theweathergotworse.A.WhenB.BeforeC.AsD.While7.You’dbetterwearstrongshoes_____we’lldoalotofwalking.A.forB.sinceC.nowthatD.as8.Iwanttousethesamedictionary______wasusedyesterday.A.whichB.whoC.whatD.as9.Heisn'tsuchaman______heusedtobe.A.whoB.whomC.thatD.as10..HeisgoodatEnglish,______weallknow.A.thatB.asC.whomD.what11.Idon'tlike______asyouread.A.thenovelsB.thesuchnovelsC.suchnovelsD.samenovels12.Ihaveboughtsuchawatch_______wasadvertisedonTV.A.thatB.whichC.asD.it13.Heisnotsuchaman_______wouldleavehisworkhalfdone.A.thatB.whichC.whoD.as14.Iwanttousethesametools_______usedinyourfactoryafewdaysago.A.aswasB.whichwasC.aswereD.which15.Johngotbeateninthegame,_______hadbeenexpected.A.asB.thatC.whatD.whoKeys:ACBCCCDDDBCCDCA課后作業(yè)1._______isknowntoeverybody,themoontravelsroundtheearthonceeverymonth.A.It B.AsC.That D.What2.________ismentionedabove,thenumberofthestudentsinseniorschoolisincreasing.A.Which B.AsC.That D.It3.Theresultoftheexperimentwasverygood,__________wehadn’texpect.A.when B.thatC.which D.what4.Johnsaidhe’dbeenworkingintheofficeforanhour,__________wastrue.A.he B.thisC.which D.who5.Hemadeanotherwonderfuldiscovery,__________ofgreatimportancetoscience.A.whichIthinkis B.whichIthinkitisC.whichIthinkit D.Ithinkis6.＿＿＿＿isknowntoeveryone,themoontravelsroundtheearthonceeverymonth.A.ItB.AsC.ThatD.What7.＿＿＿airistoman,soiswatertofish.A.SinceB.JustC.LikeD.As8.Wemustdotheexperimentcarefully＿＿＿M(jìn)issLiutoldus.A.whatB.sinceC.asD.while9._____,Carolinacouldn’tgetthedooropen.A.TryasshemightB.AsshemighttryC.ShemightastryD.Mightsheastry10.___Iexplainedonthephone,yourrequestwillbeconsideredatthenextmeeting.A.WhenB.AfterC.AsD.Since11.Danbyleftwordwithmysecretary______hewouldcallagainintheafternoon.A.whoB.thatC.asD.Which12.Allthedishesinthismenu,_______otherwisestated,willservetwotothreepeople.A.asB.ifC.thoughD.unless13.______hetalksalotabouthisfavoritesingersafterclass.A.quietstudentashemaybeB.QuietstudentashemaybeC
