不定冠词课件


第四节 冠词

Mia

一.什么是冠词 冠词是虚词,本身不能单独使用,也没有词义, 它用在名词的前面,帮助指明名词的含义。英语 中的冠词有三种,一种是定冠词(the Definite Article : the ),另一种是不定冠词(the Indefinite Article: a和an ),还有一种是零冠词 (Zero Articl

e)。不定冠词用在单数名词前,表 示泛指;定冠词用在名词前,表示特指。 如:

a book 一本书

an egg 一个鸡蛋

the elephant 那只象

1. 不定冠词a,an只用在可数名词单数前,基本意思是 “一个”。其中,a用在读音以辅音开头的单词前,an 用在读音以元音开头的单词前。如: a pencil a desk a bottle an old man an apple an eraser

2.定冠词 the在元音前读/i/,在辅音前读/?/ 。如: in the /i/evening in the/?/morning

用不定冠词an a 填空
an 1.( ) old woman dictionary 3. ( an) honest boy 5. ( a) one-eyed elephant 6. ( an) exercise book 8. ( a) history book 10.(an) English song

2.( a ) useful
4.( an ink-bottle ) 7.( a) yellow shirt 9.(an umbrella )

【易错点】: ⑴有些名词虽然首字母是元音字母,但发音却以辅音 开头。 (错)an university ——(正)a university一所大学 (错)an uniform ——(正)a uniform一套制服

⑵有些名词虽然首字母是辅音字母,但名词发音却以元音 开头,这时名词前要用an。 (错)a hour ——(正)an hour (错)a honest boy ——(正)an honest boy 一个 诚实的孩子

不定冠词(a, an) 的用 法

1.A 和An )表示数量“一”,相当于one。
1

There are twenty—four hours in a day. There are seven days in a week. 2) 泛指一类名词中的某一个。 Liu Xiang is a famous player. Cheng Long is an actor. 3)表示一类人或物。 An elephant is stronger than a horse.
4)用于表示时间、速度、价格、重量、长度等单位名词 前,表示“每一”的意思,相当于every/per. 如:Mr. Green goes to the cinema once a week. This cloth is 10 yuan a meter.

5)表示某一个人或事物,相当于some /certain
I have a watch.

A gentleman wants to see you.
6)表示同样,一样the same

John and I are of an age.
Birds of a feather flock together. 7)第一次提到某人或某物,不定冠词起介绍作用。 如:Yesterday I saw an old man. He’s Tom’s father. He is a teacher. There is a new book on the desk.

不定冠词的用法
例题:
D The Wilsons live in _____ A-shaped house near the coast. It is _____ 17th century cottage. (04浙江) A. the , / B. an, the C. /, the D. an, a

该句意为“威尔逊先生一家住在海边的一幢A 型房子里,那是一幢十七世纪的屋子。”两处 都表示“一幢“,A-shaped 是元音开头,该用 an;而 seventeenth是辅音开头,所以该用 a。

2.A 和An的特殊用法
1)用于物质名词前,表示一种,一场,一缕,一阵,一份 如:Longjing is a famous Chinese green tea. What a heavy rain! An ice coffee for me.

I saw a smoke in the distance.

2)用于抽象名词前表示:①表示一种,一场等 例如:
Translation is an art. It was a just war.

②表示动作的一次,一例等 例如: He went out for a smoke.

You have done me a kindness, thank you.

③表示引起某种情绪的事 例如:
It is a pleasure to work in China.

It’s an honor to meet you . ④表示某一品质的人和事 例如:
Jane was a grate success in the play.

In some places white bread is a luxury.

3)用于专有名词前 ①表示某一个 或 一个叫…….的人 A Mr Johnson phoned and left a message for you. ②表示与之相似的人或物 例如: He wishes to be an Edison.

③表示民族,社团,家庭中的一员或是某人创作的作品 之一。例如:
I found a Qi Baishi in a second—hand book shop. I’m a Han and my wife is a Miao.

7)the second (third…);a second (third…) 序数词前用定冠词时,强调顺序的排列。 如: I live on the second floor.? 序数词前用不定冠词时,表示“又一;再一” (another),其“顺序”的语气很弱,它强调程 度。如: Although he had failed three times, he didn’t give up. He stood up again and tried a fourth time.

“Taylor 夫人有一个在绘画方面极有天赋的八岁 的女儿,她已经两次获得全国大奖了。” eight 是元音开头,所以该用 an;而后面的 have a gift for为一短语,表示“在 … 方面有天赋”, 故答案为C。

What a brave boy he is ! 2.不定冠词用在so,as.too,how+adj 之后 So/as/too/how+adj+a/an+单数名词 It’s too difficult a book for us. How brave a boy he is ! 即: 例如:

She is as clever a girl as you can wish to meet.
