重要学术名词--爆破音：[p] [b] [t] [d] [k] [g]
爆破音+爆破音=失去爆破 Tips： 六个爆破音中任意两个相遇，一个爆破音后紧跟着另一个爆破音时，前面一个音点到为止，形成阻碍，但不发生爆破；第二个音完全爆破；若第二个爆破音在词尾，则必须轻化。 以一个爆破音结尾并以同一个爆破音开始时，只发一次音，前一个音只做好发音准备而不发音，直接发第二个音。 单词内失爆 1.active=a(c)tive [k]+[t] Students are encouraged to be active in class. 2.blackboard=blac(k)board [k]+[b] Our class has a large blackboard. 3.dictation=di(k)tation [k]+[t] We'll have dictation today. 4.football=foo(t)ball [t]+[b] There is going to be a football match tonight.
