过去一直酌么英语到底有几种语调，看来注意四种语调就足够了

Cruttenden (1986) recognizes seven tones (high-fall, low-fall, high-rise, low-rise, fail-rise, rise-fall, and mid-level).

It appeared in the author's teaching experience that only four types of tones can be efficiently taught to non-native speakers of English:

• fall
• low-rise
• high-rise
• fall-rise
