It’s an apple.  ②不同点：a用于以辅音音素开头的单词前；an用于以元音音素开头的单词前。 e.g. Tom is a student.  I have an egg.  不定冠词 a/an 【提示】 在单词或字母前用a还是an，取决于该单词或字母的第一个读音音素，而不是该单词的第一个字母或字母本身。 如：an N，“一个字母N”。N虽然是个辅音字母，但它读作/en/，其中/e/属于元音音素，所以它前面用an。 元 音 12个单元音 长元音 [a:] [ә:] [i:] [ɔ:] [u:] 短元音 [Λ] [ә] [i] [ɔ] [u] [æ] [e] 8个双元音 [ai] [ei] [ɔi] [iә ] [eә ] [uә ] [au] [әu] 辅 音 10对 清辅音 [p] [t] [k] [f
