不定冠词最基本的用途就是用来表示“一”这概念，如：
① A stitch in time saves nine.
② Jason is an internationally known scholar.
此外，a/an 还有下列 6 种用途：
一常和time、measurement等有关的名词连用，以表示“每—” 的概念，如：
③ I teach five days a week.
④ This type of vegetables is sold at one dollar a kilo.
⑤ My car usually runs sixty kilometres an hour.
二常和 hundred, thousand, dozen 以及数目及数量连用，如：
⑥ That factory turns out at least a hundred tyres a day.
⑦ Noel's monthly salary is a thousand dollars.
⑧ I have a number of sponsored students.
⑨ Mary has a lot of money.
三在“of / at”后面出现，以表示“同一类”这概念，如：
⑩ Birds of a feather flock together.
11. Please come one at a time.
12. Things of a kind come together, so do people of a mind.
四常在“rather, quite, many, half, what, such”等字后面出现，形成固定用法，如：
13. Tom is rather a fool.
14. I think Chinese is quite a useful language.
15. Many a student has asked that question.
16. The visitor left half an hour ago.
17. What a fine day it is!
18. How can you say such a thing?
五用在“so, as, too, how +形容词”这些结构里，如：
19. We have not had so hot a day before.
20. Susan is as clever a girl as Anna.
21. That is too difficult a book for beginners.
22. No one knew how serious a problem it was until later.
六出现在许多惯用语中，如：
23. Bob always has a bone to pick with others.
24. Some students turned a deaf ear to the teacher's advice.
25. All must learn a language with an eye to mastering it.
26. I hope you will make an effort to attend the meeting punctually.
27. Jason has an aversion to being idle.
28. The news of Jack's sudden resignation came as a bolt from the blue.
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。例如：
A Mr. Ling is waiting for you. 有位姓凌的先生在等你。
2） 代表一类人或物。例如：
A knife is a tool for cutting with. 刀是切割的工具。
Mr. Smith is an engineer. 史密斯先生是工程师。
3） 组成词组或成语，如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等
a和an同样是一个的意思的，但用法不同.an的后面加的名词一定要是元音字母开头,比如:an apple,an egg..
a.e.i.o.u.这些就是元音．所以如果单词前是由这五个元音字母组成的话，那么就要用an．如果不是就反之用a.
楼上的不对
不是元音字母，而是发音
第一个音节发a,e,i,o,u的音的用an
其他用a
