一、什么是不完全爆破
6 个爆破音：
/p/ /b/ /t/ /d/ /k/ /g/
当爆破音 + 辅音（不是元音）连在一起时，前面的爆破音只摆口型、不送气、不发声，只停顿一下，这就叫不完全爆破。
小结
二、最常见 3 种情况
1. 爆破音 + 爆破音
- sit down → si(t) down
- blackboard → blac(k)board
- good bye → goo(d) bye
2. 爆破音 + 摩擦音 /f v s z θ /
- don’t say → don’(t) say
- get through → ge(t) through
3. 爆破音 + 鼻辅音 /m n / 或舌侧音 /l/
- good morning → goo(d) morning
- at night → a(t) night
- at last → a(t) last
三、简单口诀
遇辅音，不爆破，
只摆型，轻停顿，
后面音，接着说。
四、一句话总结
爆破音后面不是元音，就轻轻停一下，不读出来。
1. Last week, a hurricane swept through Cuba and hit the southern United States.
sweep through 席卷，横扫
eg:The fire swept through the forest. 大火席卷了整片森林。
