不定冠词a和an来源于数词one,当今的an在形式上与之较为接近。不定冠词的基本概念是“非特指”,即用以指某类人或物中的任何一个或某一个,相当于汉语中数目概念较弱的“一”,如:
A triangle has three angles.
A tiger has escaped.
不定冠词有a和an两个,它们在概念上并无不同,只是a用于辅音音素(包括半元音/hw/,/w/,/j/)前,读作/ə/,如a book,a boy,a pen,a girl。注意,在念作/ju/的元音字母u前要用a,因为/ju/以辅音音素开头。如a unit,a uniform。an用于元音音素(包括单元音和双元音)之前,一般读作/ən/。如an ox,an elephant。注意an也用在不发音的后接元音音素的辅音字母h开头的字之前,如an hour,an honest man。还有一些法国、西班牙、意大利等罗曼语族的词汇,h也不发音,这种情况下也用an,如:an haute cuisine。
在强调a或an时,则要分别念作/e/或/æn/,如:
A is used before a consonant sound while an is used before a vowel sound.
希望我能帮助你解疑释惑。
