1. 表示“一”这个数量概念,比one意思稍弱
e.g.: The plan will be ready in a week or two.
2. 表示某人或某物,但不具体说明哪个, 相当于any
e.g.: This poem was written by a student.
注:在1,2两项中,如果名词变复数,把a换成数词或不定代词some, any等即可。
e.g.: The plan will be ready in three weeks.
3. 表示某一类人或事物
e.g.: Even a child can answer this question.
注:句中名词变复数时,去掉不定冠词a/an即可。
4. 和表示时间或度量衡的名词连用表示“每日”、“每斤”等
e.g.: I take a two-mile walk twice a day.
5. 用于固定词组
e.g.: have/take a shower have/take a bath
take a walk give a lecture
a lot of a couple of
as a rule have a headache
a few a little a bit追问没6?
6. 不定冠词用于有形容词修饰的季节, 日期前面
The traffic accident happened on a Sunday towards the end of July
