不定冠词

不定冠词有两个a和an.

a 用在以辅音开头的词前,an用在以元音开头的词.

a 一般读作[?],an一般读作[?n].

在强调或单独读时分别读作[ei] 和 [?n].

如:

an island 一个岛

a small island 一个小岛

an elephant 一头大象

a university 1 一所大学

an honest 2 man 一个诚实的男人,等等。

不定冠词a 来源于数词 one 指一个的意思,与可数名词单数连用,表示某类人或东西的一个, 例如:

他一年到头带一顶黑帽子。

天气这么好你带雨伞做什么?

不定冠词也可用于特指,

例如:A tiger has escaped 4. 一只老虎逃跑了。
