31 音节的种类： 开音节、闭音节 1.开音节：以元音字母结尾，或以辅音字母（r 除外），加不发音的e结尾的重读音节叫开音节。在开音节中元音读它的“字母名称”的读音。 he [hi:], face [feis], joke [dʒəuk], go [gəu]

32 开音节又分两种情况——“绝对开音节”和“相对开音节”。
1)绝对开音节：以要读音的元音字母或后跟一个不发音的“e”结尾的音节，如:he, she, me, shy, no, go, lie, tie, die等。 2)相对开音节：发音的元音字母后跟一个（或多个）发音的辅音字母+不发音的元音字母“e”构成的音节。 如：lake, cake, take, haste, strange, time, waste, mute, paste, nose, rose, these
