英语音标ppt课件

1.什么是国际音标？由于英语的拼写形式和读音有很大的分歧,所以无法完全根据字母来读音。为了精确地学习和掌握语音,就要借助一种注音手段来弥补这一缺陷,于是便产生了一定数量的精确记录语音的符号，叫做“音符”(Phoneticsymbols)。国际音标（旧称万国音符）是国际语音学协会（IPA---InternationalPhoneticAssociation)于1888年拟定的一套为各国语言注音的语音符号。我们这里所说的国际音标是专门为英语注音的那一部分标音符号。目前我国通用的国际音标共有48个,其中,元音音标20个，辅音音标28个。英语元音(Englishvowels)英语元音音素共20个。分单元音和双元音两大类。单元音的分类a.前元音：/i:/,/i/,/e/,/?/b.后元音：/ɑ:/,/?/,/?:/,/u/,/u:/,/Λ/c.中元音：/?:/,/?/双元音的分类a.合口双元音：/ei/,/?u/,/ai/,/au/,/?i/b.集中双元音：/i?/,/ε?/,/u?/英语辅音(Englishconsonants)(共28个）a.爆破音/p/,/b/,/t／,/d/,/k/,/ɡ/b.摩擦音/f/，/v/，/θ/，/e/，/s/，/z/,//，//，/h/,/r/c.破擦音/t∫/，/d?/，/tr/，/dr/，/ts/，/dz/d.鼻音/m/,/n/,/?/e.旁流音（舌侧音）/l/f.半元音/w/,/j/前元音?/i:/?feel?heat热?leap跳?/?/?bad?land?Dad?map?hat?/i/?fill?hit?lip嘴唇?/e/?bed?lend?dead?met?head前元音练习beebilldeepdigtasktestGivemeabeefsteak,peas,andbeer,please.Catchthatmadblackcat．Betterlatethannever.(迟做总比不做好)Bettertodowellthantosaywell.(口说不如实干)Afriendinneedisafriendindeed（患难见真情）后元音?/?:/?all?fall?hall?/u:/?goose鹅?food?/?/?boss?fox?hot?/u/?good?foot?loose松的?/ɑ:/?calm?look?/Λ/?come?Alargearmymarchedpastthefarmyard．?It'shardtoseeanystarsinthedarksky．?Theclockisstopped,it'snotlong．?Losttimeisneverfoundagain．?Whosaidthesoupwastoocool??Asarule,theskiesareblueinJune．?Helookslikeagoodcook．?ItookmybookandlookedatitaslongasIcould．中元音/?://?/?earth?search?bird?another?order?method?church?doctorMyyoungerbrotherisadoctor．Givemesomebutterandsugar．Wewillhaveaget-togetheraftersupper．双元音/ei//e/?age?late?pain?edge?let?pen双元音/ai//?i/?bike?mine?height?boy?coin?noise?voice双元音/?u//au/?coal?pose?loan贷款?bowl碗?doubt?found?noun爆破辅音?/p/?pea?/t/?tear?/k/?class?/b/?bee?/d/?dear?/g/?glassGood,better,best.循序渐进Neverletitrest.永不停止Untilgoodisbetter.好上加好Andbetterbest.精益求精摩擦辅音/f//v/?fast?few?leaf?proof?safe?surf?vast巨大的?view?leave?prove?save?serveHeworkshardasifheneverknewfatigue.Itisverydifficultforustofinishitbeforefive.摩擦辅音/s//z/?bus?ice?loose?race?used?buzz蜂音?eyes?lose?raise?used摩擦辅音/θ//e/?thank?theme?thick?bath?breath?than?these?this?bathe?breathe?clothe?cloth/θ//s/?thin?sin?thing?faith?mouth?/e/?breathe?clothe?seethe沸腾?sing?face?mouse?/z/?breeze微风?close?seize/θ/?thank?thought/t/?tank?taught?/e/?there?they?those?/d/?dare?day?doze打瞌睡?/θ?three/?/f/?free?Athousandthanks.?Cathyhasthreebrothers.?Mr.Smithtalkedaboutthis,thatandtheother.?Thereissomething.?Theyhavebeenthereformorethanthreemonths.摩擦辅音/∫//?/?cash?fish?leisure闲暇?measure测量?ship?shoe?pleasure?vision视觉Measureformeasure.以牙还牙Shesellsseashellsontheseashore.她在海边捡贝壳。摩擦辅音?/h/?hard?he?/r/?red?road?house?who?hi?hello?write?wrong破擦辅音/ts//dz/?carts?rates?cards?raids?Seats?/t∫/?cheep?seeds?/d??choke闷塞?larch落叶松?rich/?jeep?joke?large?ridge脊破擦辅音/tr//dr/?track?tree?truck?drag?dream?drug?try?dryNevertroubletroubletilltroubletroublesyou.麻烦不找你，就别自找麻烦。鼻辅音/m//n//?/?dim朦胧的din喧闹ding唠叨?seemseenseeing?sumsunsung?whim怪想winwing舌边辅音/l/?/l//n//r/?leadneedread?lightnightright半元音/w//j/?warmyoung?wellyard?whileyield?Wherethereisawill,thereisaway.?有志者，事竟成。?Youstilllookyoung,yearafteryear.?一年一年过去了，你看起来还那么年轻。
