其实就是简单的一句话 I like eating tomatoes. 它包含的意思可不止两种,属于语用学范畴了.如：

1）I like eating tomatoes instead of dislike eating it.(这句话的强调在“喜欢”,要重读 like)
2）I like eating tomatoes, rather than other vegetables.(强调在“西红柿,要重读 tomatoes”)
3) I like eating tomatoes.He doesn't like it.(强调在"我",要重读 I)
侧重点不同 语音重点亦不同不同的语调表达的意思是不一样的
你可以仔细体会“Thank you.”的不同语调的不同意思,不像想象的那样简单哦.
