【相关阅读】英语四级冠词语法讲义
冠词分不定冠词(indefinite article)和定冠词(definite article)两种,一般无句子重音。
1)不定冠词a,an
a) a和an均用在单数名词之前,表示某一类人或事物中的"一个",相当于汉语的"一",但不强调数目观念。
b) a用在辅音之前,an用在元音之前。如:a notebook一个笔记本,a cigarette一支香烟,an old man一位老人,an English class一堂英语课。
字母u读作[ju:]时,由于第一个音[j]是辅音,故前面用a,不用an。如:a useful book一本有用的书,a university一所大学。字母h如不发音,第一个音又是元音,前面用an而不用a,如an hour [?n'au?]一小时,an honest [?n' nist] person一个诚实的人。
c) a和an在句中分别弱读作[E]和[En]。
2)定冠词the
a)表示某一类人或事物中的."某一个"或"某一些",相当于汉语的"这"或"那"。
b)不论单数名词或复数名词,也不论可数名词或不可数名词,前面都可以用the。
c)在元音前读[Ti],辅音前读[TE]。如the evening [Ti5:vniN] (傍晚),the car [TEkB:] (汽车);在元音字母u发[ju:]和半元音字母。y发[j]时,仍读[?TE]。如the unit [TE5ju:nit] (单位),the yard [TEjB:d] (院子)。
英语中不定冠词a (an)的用法
1)指一个人、动物或一件事物属于某一类。如:
Xiao Xu's father is a miner.小徐的父亲是矿工。(而不是其他工种)
Give me a ballpen , please.请给我一支圆珠笔。(而不是钢笔或其他种类)
2)指任何一个人、动物或一件事物。如:
A steel worker makes steel.钢铁工人炼钢。(意即任何一个钢铁工人都炼钢)
A triangle has three angles.三角形有三个角。(意即任何一个三角形都有三个角)
3)指某人或某物,但不具体说明何人或何物。如:
He comes from a firm in Beijing.他来自北京某一家公司。
A young man wants to see you.有个青年人要见你。
A car stopped in front of the gate.一辆汽车停在大门前。
4)不定冠词还可指"事物的单位",如"每日"、"每斤"等。如:
Butter is 4 yuan a kilo.黄油四元钱一公斤。
He drove the car at 18 miles an hour.他行车速度为每小时十八英里。
The Chinese Export Commodities Fair is held in Guangzhou twice a year.中国出口商品交易会每年在广州举行两次。
