第五课 英语合口双元音修改版

英语双元音Diphthongobjects英语合口双元音根据发音的特点，英语双元音可分为：合口双元音与集中双元音。英语双元音是由两个音合二为一，发音时由第一个音向第二个音滑动，滑动过程中没有任何停顿。双元音发音饱满、圆润、悦耳动听。英语双元音由第一个音向第二个音滑动过程中，第一个音长而响亮，并自然而连贯地向第二个音滑动，第二个音短而含糊；一般来说，由第一个音向第二个音滑动时，不到第二个音的发音部位，发音即告完成。需要注意的是双元音是从一个音节向另一个音节滑动，要避免把双元音单音化。英语合口双元音（1）发双元音/e/时，口形由/ɛ/向/ɪ/滑动，下巴向上合拢，舌位随之抬高。注意双元音的发音特点是前重后轻、前长后短。/e/音素体验atakemakenameaiwaitrainpainaymaywaydayeieightreignsleigheytheygrey容易出现的错误1.不够长，读作短音。2.不恰当地把/e/读成单元音英音美音区别音值一样，音标不同。对话演练(Dialogues)A:HappybirthdaytoKate.1)A:Whatabeautifulcake!B:Yes,it'sKate'sbirthdaycake.A:Howoldisshe?B:Sheiseighteentoday.B:Waitaminute,Jane.it'stimetobakethebread.2)A:Mrs.Tayor‘sagooddressmaker，isn’tshe?B:Yes.Thenewdressshemadeisgreat.A:MaybeIneedhertomakeoneforme.脱口而出(SpeakOut)7)ThereisnowayIcangetoutofit.1)Nopain,nogain.2)Callaspadeaspade.3)Apennysavedisapennygained.4)Hastemakeswaste.5)Ihatetotroublehim.6)Shealwayscallsaspadeaspade.吃得苦中苦，方为人上人。实话实说。一份耕耘，一份收获。欲速则不达。英语合口双元音（2）发双元音/o/时，口形由中元音/ə/向/ʊ/滑动，双唇由扁平变为合圆形，到/ʊ/的位置就停止发音。/o/音素体验onohomepostoaboatloadcoatowlowknowbowloushoulder容易出现的错误1.不够长，读作短音。2.不恰当地把/o/读成单元音或者读成中文中的“欧”。英音美音区别教材不同，解释不同。1）这个音含有/ə/和/u/两个成分。2）发音是由舌位比/ɔ/稍高的圆唇后元音/o/向舌位更高一些的/ʊ/滑动，结束时稍带/ʊ/音，但主要是/o/音的延长。对话演练(Dialogues)B:Inthatcase,wecouldjuststayathome.2)A:Whatwillyoudotomorrow?B:Let’sgototheSummerPalacetorowaboat,shallwe?A:Oh,I'velistenedtotheradio.Thebroadcastsaystomorrowitwillrain.A:Thetomatoes?They'reinthebowlinthecupboard.2)A:Joe,todayyoumakesupperforus,I'vegotalittleheadache.B:OK,Rose.Where'rethepotatoes,Ican’tfindthem.A:Theyareinthebagunderthetable.B:Oh,heretheyare.Butwherearethetomatoes,Rose?B:Onekilo.Thanks.3)A:I’mgoingtothegrocerystore.Wouldyouliketogowithme?B:Sorry.Ihavetowritealetter.A:AnythingIcandoforyou?B:Canyougetsometomatoesforme?A:OK.Howmanydoyouwant?脱口而出(SpeakOut)6)Iknowwhatyouknow.1)Don‘tgohomealone,Joan.2)Littlestrokesfellgreatoaks.3)Asyousow,youshallmow.4)Astrawwillshowwhichwaythewindblows.5)Ihopenothingiswrong.滴水穿石。种瓜得瓜，种豆得豆。英语合口双元音（3）发双元音/aɪ/时，由舌位低、口形大的前元音/a/向舌位高、口形小的/ɪ/滑动。发音时舌尖要抵住下齿。/aɪ/音素体验iIwifeniceymybystyleuybuy容易出现的错误1.不够长，读作短音。2.不恰当地把/aɪ/读成单元音/æ/或者中文中的“爱”。英音美音区别教材不同，解释不同。1）发/a/时舌尖不抵下齿。2）发音时舌尖始终抵住下齿。对话演练(Dialogues)B:Sure.I’vetriedit，l)A:Youboughtanewmotorcycle，didn‘tyou?B:Yes.Howdoyoulikeit?A:It‘sreallystylish.Didyourideit?B:Thatwouldbemypleasure.2)A:It'snoteasytomakeadinnerforsix,includingMike.B:Don'tworry.Icouldgiveyouahand.Mymeatpiesareterrific.A:OK.Youcouldmakesixmeatpiesforusasthemaindish.B:Well,Ipreferpineappleflavoricecreams.3)A:TrytheFrenchfries.B:Well,thesmell'ssonice.Mm,theyarefriedreallywell.A:Let‘shaveicecreamsfordessert.B:Howmanyicecreamsarethereinthefridge?A:Letmesee.Nine.Threeofthemarepineappleflavor.脱口而出(Speakout)1)Strikewhiletheironishot.2)Timeandtidewaitfornoman.3)Astitchintimesavesnine.4)Greatmindsthinkalike.英语合口双元音（4）发双元音/aʊ/时，由舌位低，口形大的/a/向舌位高、口形小的/ʊ/滑动，结束时双唇收圆稍向前突。/aʊ/音素体验ouloudloungeroundowbowdowntown容易出现的错误1.不够长，读作短音。2.不恰当地把/aʊ/读成中文中的“奥”。3.当/aʊ/后跟有/n/时容易读成/a:n/,如:down,town.英音美音区别教材不同，解释不同。1）发/a/时舌尖不抵下齿。2）发第一个音时舌尖要抵住下齿，发第二个音的时候舌尖后缩，不抵下齿。对话演练(Dialogues)B:That'smysonsinging.Buthesoundslikehe’sshouting.1)A:Nicetomeetyou,Mrs.Brown.B:Nicetomeetyou,too.Mr.Howard.A:Listen!Who’sshouting?A:That'swhatIamworriedabout.2)A:Ineedsomeonetohelpmewiththehousework.B:Whatdoyouwanthimtodo?A:Well,milkthecow,killthemouse,washthetowel,andcleanthehouse.B:Howcouldyoufindtheonethatcoulddothesethingswell?脱口而出(SpeakOut)6)Howaboutgoingdowntown,now?l)Roundandroundhedancedinfrontofthecrowd.2)Brownspendshourafterhouramonghisflowers.3)MarchwindandAprilshowersbringMayflowers4)Getoutofmyhousenow.5)I‘veheardsomuchaboutyou.“Averygoodsupper,”sayshe.7)Theowllookeddownwithhisgreatroundeyes.Atthelowcloudsandthedarkskies，“Agoodnightforscouting,”sayshe.WithneverasoundI‘llgoprowlingaround,Amouseortwomaybefoundontheground.Orafatlittlebirdinatree.SodownheflewfromtheoldchurchTower.Themouseandthebirdiecrouchandcower,Backhefliesinhalfanhour，英语合口双元音（5）发音要点:发双元音/ɔɪ/时，由后、低元音/ɔ/向前、高元音/ɪ/滑动，口形由开、圆逐渐变为合、扁，尾音短促。/ɔɪ/音素体验oioilboilvoiceoyboyannoytoy容易出现的错误容易把双元音/ɔɪ/的第二个音/ɪ/读成/i/，把toy读成/tɔi/，oil读成/ɔil/，要注意防止。英音美音区别美语双元音/ɔɪ/和英语双元音/ɔi/的发音基本相同，即由后、低元音/ɔ/向前、高元音/ɪ/滑动，口型由开圆逐渐变为合扁。对话演练(Diologues)B:Andsomecorn,that‘sall.1)A:CanIhelpyou?B:Iwantsomeoil,someoysters,andsomeboiledeggs.A:Anythingelse?A:No,Iwon’t.2)A:IwanttobuyatoyforRoy.B:ForRoy?Youwanttobuyhimanothertoy?A:Whynot?Heenjoysplayingwithtoys.B:Heenjoysdestroyingtoys.You'dbetternottospoiltheboy.脱口而出(SpeakOut)6)It'sajoytowatchtheboyplayingwithhistoy.1)Comeandenjoytheoyster.2)Don’tspoilRoybygivinghimtoomanytoys.3)Thesmellofoilismostannoying.4)Letusjoinhandsinfriendship.5)I'minahurry,sogettothepoint.音素对比e/eɪo/əʊaɪaʊɔɪlanelonelineloudloinmainmowminemountmoistpainbonepinepoundpointfaintfoefindfoundfoible英语双元音小结(合口双元音)英语里共有八个双元音，根据发音的特点可分为两大类:合口双元音/e//o//aɪ//aʊ//ɔɪ/与集中双元音/ɪə//ɛə//ʊə/。英语双元音的发音特点:1.双元音是有两个不同的元音组成的，口形舌位有变化(发单元音是口形舌位保持不变)。2.双元音中两个元音的音长也不相等，前长后短，第一个元音的音长比第二个长一些。3.前重后轻，发音时第一个元音重些，第二个轻些，由强渐弱。5.前面的音较为清晰，后面的音较为模糊，双元音中的第一个元音发音清楚响亮，向第二个元音滑动，在到达第二个元音的发音位置时即可停止，不必把第二个音发得那么清楚。4.两音密合，一气呵成，由第一个元音向第二个元音滑动，中间不要停顿，切忌把两个音分开来念。英语合口双元音发音示意图:
