Book 2 Unit 5 Music 语音知识和过去分词练习 湖北省嘉鱼县第一中学 高一（5）班 熊亚玲 2026年3月26日 1. What are included in plosives (爆破音)? 2. What is incomplete plosion (不完全爆破)? 3. Why does this phenomenon occur in pronunciation? Voiced浊音的consonants辅音 Voiceless清音的consonants辅音 /b/, /d/, /g/ /p/, /t/, /k/ /b/, /d/, /g/ /p/, /t/, /k/ /b/, /d/, /g/, /p/, /t/, /k/ other consonants (辅音) To speak English with more ease and fluency. Pronunciation发音 Let’s think about the following questions. 认识爆破音 (Plosive Consonants) 定义：发音时气流在口腔中受阻，然后突然冲破阻碍发出的声音，分为3对清浊辅音。 双唇爆破音 /p/ (清) / /b/ (浊) 紧闭双唇，气流冲破阻碍 pen, apple | book, baby 齿龈爆破音 /t/ (清) / /d/ (浊) 舌尖抵住上齿龈，突然弹开 table, cat | dog, red 软腭爆破音 /k/ (清) / /g/ (浊) 舌后部抵住软腭，突然分开 key, cake | go, big 发音要点：每对辅音发音口型相同，区别在于清辅音声带不振动，浊辅音声带振动。可手按喉咙感受震动。 1.7.2013 同学们好！今天我们来学习英语中非常重要的一类辅音——爆破音。顾名思义，爆破音就像气球爆炸一样，气流在口腔里被堵住，然后突然冲出来发出声音。英语里一共有6个爆破音，它们是三对“双胞胎”。大家看屏幕，第一对是双唇爆破音/p/和/b/，发音时需要紧闭双唇。第二对是齿龈爆破音/t/和/d/，发音时舌尖要顶住上齿龈。第三对是软腭爆破音/k/和/g/，发音时舌后部要抵住软腭。每一对的口型都一样，区别在于清辅音发音时声带不振动，而浊辅音发音时声带要振动。大家可以把手放在喉咙上感受一下，发/b/、/d/、/g/时能感觉到明显的震动。 ‹#› 掌握不完全爆破 (Incomplete Plosion) 定义：当一个爆破音后面紧跟着另一个辅音时，前一个爆破音只形成阻碍，不发生爆破。掌握此技巧能让发音更地道流畅！ 爆破音 + 爆破音 规则：前一个失去爆破 例1: blackboard /blækbɔːd/ (k不爆破) 例2: goodbye /ˌɡʊdˈbaɪ/ (d不爆破) 爆破音 + 摩擦/破擦音 规则：前一个不完全爆破 例1: picture /ˈpɪktʃə/ (k不爆破) 例2: keep silent /ˈkiːpˈsaɪlənt/ (p不爆破) 爆破音 + 鼻音/舌侧音 规则：前一个不完全爆破 例1: good morning /ˌɡʊdˈmɔːnɪŋ/ (d不爆破) 例2: at last /ətˈlɑːst/ (t不爆破) Tip: 做好口型准备，稍作停顿，不送气出声。 1.7.2013 接下来我们学习一个让英语发音更地道的技巧——不完全爆破。简单来说，当一个爆破音后面紧跟着另一个辅音时，我们不需要把前面的爆破音完全发出来，只需要做好口型，稍作停顿，然后直接发后面的音就可以了。 比如单词“blackboard”，中间的/k/后面是/b/，所以/k/不需要爆破出来。再比如“good morning”，“good”结尾的/d/后面是/m/，/d/也只需要做口型，不发音。 大家跟着我一起读一下这些例子，感受一下不完全爆破的发音方法。 ‹#› 实战练习与总结 实战练习：不完全爆破 a big boy last year Good luck I don’t know. She has a black bag. 核心知识点总结 爆破音分类：共6个，分3对清浊辅音 /p/-/b/, /t/-/d/, /k/-/g/。 现象意义：口语中常见的连读现象，掌握后发音更地道流畅。 核心规则：当爆破音后接其他辅音时，前一个只做口型，不完全发音。 1.7.2013 现在到了我们的实战练习环节！请大家大声朗读屏幕上的短语和句子，注意运用我们刚刚学的不完全爆破规则。比如“a big boy”，“big”结尾的/g/后面是/b/，所以/g/要不完全爆破。读完之后，我们来总结一下今天的内容：我们学习了6个爆破音，分为三对清浊辅音。更重要的是，我们掌握了不完全爆破的规则，这能让我们的英语听起来更地道、更流畅。记住这个核心规则：当爆破音后面跟着其他辅音时，前一个爆破音就不完全爆破。希望大家在课后多加练习，把今天学到的知识运用到实际的口语交流中去！ ‹#› How many roads must a man wal(k) down Before you call him a man?
