不完全爆破是指爆破音（/p,b,t,d,k,g/）在特定情况下不完整释放气流，仅作出发音姿势而不完全爆破的现象。不完全爆破的三种主要情况：(1)爆破音+爆破音当一个爆破音后面紧跟另一个爆破音时，第一个爆破音失去爆破（仅作口型停顿，不释放气流）。爆破音（6个）：/p,b,t,d,k,g/

示例：/t/+/k/:act

kind[æk

(短暂停顿)kaɪnd]/d/+/g/:bad

girl[bæ

(短暂停顿)gɜːl]/p/+/t/:stop

talking

[stɒ

(短暂停顿)

tɔːkɪŋ]

02PresentationReadandlearn.(2)爆破音+摩擦音/破擦音爆破音后接摩擦音（如/f,v,s,z/）或破擦音（如/tʃ,dʒ/）时，爆破音不完全释放。摩擦音（9个）：/f,v,θ,ð,s,z,ʃ,ʒ,h/破擦音（2个）：/tʃ,dʒ/示例：/t/+/ʃ/:whiteshoes/waɪ(短暂停顿)ʃuːz/

/d/+/ð/:and

that[æn(短暂停顿)ðæt]/k/+/s/:taxi['tæ(短暂停顿)si](3)爆破音+鼻音/边音爆破音后接鼻音（/m,n,ŋ/）或边音（/l/）时，爆破音通过鼻腔或舌侧释放，而非口腔爆破。示例：/t/+/n/:button/'bʌ(短暂停顿)n/

注意事项:

连读中的爆破音：快速口语中，爆破音可能完全省略(如Isit→/ɪzɪ(t)]/)。Pronunciation02PresentationReadandlearn.Readtheconversationandunderlinetheincompleteplosions.A:Isitrainingagain?B:Yes.Andtheheavyrainwilllasttilltomorrowafternoon.A:That’sawful!B:Ihopetheheavyrainwillnot
