冠词是用在名词前面.doc

冠词是用在名词前面,帮助说明名词所指的人或事物,是泛指还是特指的词。冠词是一种虚词。
冠词分不定冠词(The Indefinite Article)和定冠词(The Definite Article)a, an是不定冠词,the是定冠词。
an, a是不定冠词,仅用在单数可数名词前面,表示“一”的意义,但不强调数目观念。a用在以辅音(指辅音音素)开头的词前, an用在以元音(指元素音素)开头的词前,如:
a boy an hour
a history class an island
a university an elephant
a hero an old man
不定冠词的用法:
1. 表示人或事物的某一类
A steel worker makes steel.
A plane is a machine that can fly.
2. 表示某一类人或事物中的任何一个。
This is an apple.
His father is a teacher.
3. 泛指某人或某物,但不具体说明何人何物。
rade is waiting for you downstairs.
I met an old man on my way to school.
4. 表示“一个”的意思
He will be back in a day or two.
He tried to send a picture of a face.
5. 有时也表示“每”的意思
错误分析
We have three meals a day.
我们一日三岁.
He walks ten miles an hour.
他一小时走10英里。
We have six classes a day.
我们一天上六节课。
He drives the car at thirty miles an hour.
如果把不定冠词后的名词变为复数,只把不定冠词去掉还不行,还得补上一个数词或不定代词(some, any)
The plan will be ready in a few days.
这是因为“一个”或“某个”变为复数时,就成为“几个”或“某几个”的缘故。
