Edit英语语音基础知识
要想说好英语语音，就要有英语语音的一些基本知识。以下内容供你参考。
Edit1．关于语音的几个概念
1)字母：语言的书写形式。元音字母a, e, i(y), o, u,
2)音标：词的语音形式。
3)音素：音的最小的单位。英语中有48音素。
4)音节：由元音和辅音构成的发音单位。ap'ple, stu'dent, tea'cher, un'der'stand
5)元音：发音响亮，是乐音；口腔中气流不收阻碍；是构成音节的主要音。英语中有20元音。
6)辅音：发音不响亮，是噪音；口腔中气流受到阻碍；不是构成音节的主要音。英语中有28辅音。
7)开音节：a) 辅音+元音+辅音+e name bike ;b) 辅音+元音 he, go, hi
8)闭音节：a) 辅音+元音+辅音 bad, bed, sit, hot, cup; b)元音+辅音it
9)重读音节：单词中发音特别响亮的音节。
