失去爆破音 专题学习(人教版英语)

【1】失去爆破

当一个爆破音后面紧跟着另一个爆破音时,前面的爆破音不发生爆破。方法是:对于前一个爆破音,只作发音的姿势,刚要发出时,立即发出第二个爆破音。这种现象叫做失去爆破。

爆破音 + 爆破音→失去爆破

(爆破音6个:/p, b, t, d, k, g/)

例如/p, b, t, d, k, g/这样的组合出现时,前面的爆破音就需要失去爆破了。例如:

what time /`wt taim/

goodbye /,gud`bai/

bedtime /`bedtaim/

big kite /`big `kait/

【2】不完全爆破

当一个爆破音后面紧跟着一个摩擦音、破擦音、鼻辅音或舌边音时,前面的爆破音只作部分爆破。方法是:对于前一个爆破音,作好发音的姿势,刚发出时,立即过渡到第二个摩擦音或破擦音上去。第一个爆破音发出的声音是非常轻微的,有时甚至听不出来。这种现象叫做不完全爆破 。

a.爆破音 + 摩擦音或破擦音→不完全爆破

(摩擦音10个:/f, v, , e, s, z, ∫, , r, h/)

(破擦音6个:/ts, dz, tr, dr, t ∫, d/)

例如/t t∫, td, d t∫, dd, p t∫, pd, g t∫, gd/等。这样的组合出现时,前面的爆破音就需要不完全爆破了。

例如:

picture /`pik t∫ /

big jug /`big `dΛ /

good child /`gud ` t∫aild/

that joke /`et `duk/

b.爆破音 + 鼻辅音或舌边音→不完全爆破

(鼻辅音3个:/m, n, /)

(舌边音1个:/l, =/)

例如:

good morning /`gud `m:ni/

big nation /`big `nei∫n/

mad man /`md `mn/

correct note /k `rekt `nut/

也就是说,6个爆破音/p, b, t, d, k, g/跟所有辅音(26个)相连,都会失去爆破。

2个半元音 /j/ /w/

20个元音

失去爆破和不完全爆破现象可以出现在同一单词中,如 notebook /`nutbuk/,也可以出现在两个单词之间,如 good morning /`gud `m:ni/。

在作语音分析时,我们往往在失去爆破和不完全爆破音的下面画上一小道线,例如 a big man, a good child, take care of your sister 等。
