  冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article)。
  不定冠词a (an)与数词one 同源,是"一个"的意思。a用于辅音音素前,一般读作[e],而an则用于元音音素前,一般读做[en]。
 1) 表示"一个",意为one;指某人或某物,意为a certain。
   A Mr. Ling is waiting for you.


 2) 代表一类人或物。
   A knife is a tool for cutting with.
   Mr. Smith is an engineer.

   a little / a few / a lot / a type of / a pile / a great many / many a / as a rule / in a hurry / in a minute / in a word / in a short while / after a while / have a cold / have a try / keep an eye on / all of a sudden
