冠词分定冠词和不定冠词两大类。定冠词特指一特定名词，不定冠词泛指一般普通名词。二.不定冠词的用法不定冠词有a和an两种形式，a用在以辅音开头的名词前，an用在以元音开头的名词前。它的用法如下：
1.表示“一个”的意思，与数词one相同。
例如：Rome was not built in a day.
罗马不是一天建成的；伟业非一日之功
The project(项目，计划) will be carried out（执行，贯策） in a year or two.2.表示一类人或事物。
例如：A dog is a faithful（忠诚的） animal.
Even a woman can do it.

间、重量、长度等单位前。
例如：He earns two thousand yuan a month.
The train is running sixty miles(英
里)an hour.
4.表示同样的人或事物，相当于the same。
例如：Birds of a feather（羽毛） flock (一群）together./They are people of a kind.
一群同样羽毛的鸟在一起/物以类聚，人以群分。 5.物质名词或抽象名词前用a 或an表示具体意义、制成品或种类。
例如：Green tea is a wonderful tea.
She is a beauty.（美人）
Please give me a coffee.
6.用于人名前，表示说话者对此人不认识，相当于“a certain”，也可指于某名人有类似性质的人或事物。
例如：A Mr. Chen came to see you this morning.
He wishes to become a Newton.7.有些世界上独一无二的东西，如sun, moon, sky, universe（宇宙）,world（世间，地球） ,earth （地球）等，一般前面要用定冠词，但当他们前面有修饰语时，则要用不定冠词。
例如：We hope we can see a full moon
tonight.
He sat in a chair, looking at a starry 布满星星的 sky.8. 在作单数可数名词定语的形容词最高级前，
如果不表示“最”，而表“非常”，则用不定冠词。例如：
That is a best dictionary.
This is a most troublesome（费事的） case.
（情形，情况)
9. 序数词前，一般有定冠词，但当表示“又一
个”时，则要用不定冠词。
例如：They have a second house.
When I sat down, a fifth man rose (动词,rise的过去式 “站起来”）to speak.
10. 季节、月份、日期、三餐前有修饰语时，
用不定冠词。
例如：We had a wonderful lunch.
We had a very cold winter last year.

例如：once upon a time （从前) in a hurry
（匆匆忙忙）
have a rest have a good time
