不定冠词(a,an)的定义

不定冠词的基本用法:

(1)不定冠词有a和an两种:a用于辅音音素开头的词前,an用于元音音素开头的词前。

例如:a boy, a city, a girl, a useful animal , an old man, an honest boy, a bad apple, a tall elephant

(2) 用来表示“一”的意思,但不强调数的观念,只说明名词为不特定者。即不具体说明是何人何物。

例如:A teacher is looking for you.  We work five days a week.

(3)不定冠词含有“一”的意思,但数量观念没有one强烈,在句子里边一般可以不必译出,但若有“一个”的意思则译出,

例如:An orange is good for you. 桔子对你有好处。

(4)一般用在可数名词单数前,指人或事物的某一种类。

例如:Bill is a student.   This is a ruler.

(5)用在某些固定词组中。

例如:a lot of, a moment ago, a few, a little
