/p/, /b/, /t/, /d/, /k/, /g/是6个爆破音
1. /p/, /b/, /t/, /d/, /k/, /g/这6个爆破音中的任何两个音素相邻时,前者不发音，只保留口型,后者发音。如:
1) He has a ba(d) col(d) today.
2) You shoul(d) ta(k)e care of the children. Gla(d) to meet you.
2.爆破音/p/, /b/, /t/, /d/, /k/, /g/在/tF/, /dV/, /W/, /T/的前面时不完全爆破。如:
1) Have you rea(d) the book abou(t) tha(t) child。
2) The thir(d) chair is broken.
3.爆破音/p/, /b/, /t/, /d/, /k/, /g/在/m/, /n/, /l/, /s/的前面时不完全爆破。如:
1) Goo(d) morning, sir.
2) Goo(d) night.
3) They are very frien(d)ly to us.
失去爆破和不完全爆破是一个意思。
在单词内部也是一个道理，比如advice中字母「d」的发音。
