2. 英音与美音的元音区别
2.1 元音区别A：卷舌音
当字母 r 出现在单词的元音字母组合中时，英音 r 不发音，美音会出现独特的卷舌音。

[?r ] her earn bird turn learn word first（基准卷舌音）
[?r] dear near
[?r ] air dare pear their where
[?r] sure tour poor
[?r] for more door floor pour before
[j?r ] fewer sure poor tour cure
[ɑ?r] fire liar buyer tired higher
[ɑ?r] hour flower tower power shower
[??r ] employer destroyer
2.2 元音区别B：[ɑ:] – [?]
英语中的元音[ɑ:]在用于[f] [θ] [s]或鼻音前时，美语发为[?]，但在字母组合lm前发音不变仍为[ɑ]。
