an hour{aʊr}

an uncle

a university{ˌjunə'vɝ sətɪ}

an office boy

a one-eyed{'wʌn'aɪ}man

an 8-piece band

an FBI man

(3)字序→【用法】(1)

(4)字义1, 2 为保留数词one之原义的用法;3,4为当不定冠词的普通用法。

补充

(1)复数构句中通常用some, any:

There are some books ...

Are there any books ...?

(2)There were a poet and a novelist.

有一位诗人与一位小说家(二人)。

He is a poet and novelist.

他是一位诗人兼小说家(一人)。

但强调一人从事两项活动或具有两种性质时,两者均须加冠词:

Molière was an actor and a playwright.

莫里哀是演员,也是剧作家。

补充

复数构句中不用some, any (参照the B1),如:

A bird has wings.改为复数构句则为Birds have wings.

用法

(1)a [an]可与形容词等修饰语连用,加於单数可数名词之前:

(例:a fine day, a very fine day);

特别注意下列语词的字序:

many a boy

【文】

(=many boys)

such a thing

What an idle girl [How idle a girl] she is!

(她是一个多么懒惰的女孩啊!)

quite a young lady

rather an idle boy

as [so, too] heavy a burden

half an hour

(2)No such disaster will happen again.

(像这样的灾害不会再发生)

You could get no greater honor than this.

(你不可能获得比这更大的荣誉了。)

在上列句子中,如加入不定冠词而说成no such a disaster, no greater an honor就错了。

(3)this, that, some之类的限定词与my, his之类的所有格,不可与a [an]并用。

(如:a this girl, this a girl, a my daughter, my a daughter等均为错误)

(4)用于称呼时的名词,不加冠词:

Hello, friend!

(喂,朋友!)

(5)当作补语的名词,表官职、地位、任务等时,不加冠词:

Alice was elected chairperson.

(爱丽丝当选为主席。)

He acted as interpreter.

(他当译员。)

(6)在某些词组或独立短语中,可数名词前也不用不定冠词:

in class

(上课)

with child

(怀孕)

go to school

(上学)

He sat in a chair, pipe in mouth.

(他坐在椅子上,口啣烟斗。)

用法

(1)当adj.用的such:

i)在修饰单数的可数名词时,通常位于不定冠词之前;如果和一般形容词合并使用,该形容词便置于such a(n)和名词之间:

I have never seen such a (beautiful) sight.

(我从来没有看过这么美丽的景色。)

ii)但如果和all, another, any, some, no, many, few等合并使用, such就要放在这些字的后面,而其后的名词,就算用单数,也不需要不定冠词:

Have you ever heard any such

rumor?

(你听过像这样的谣言吗?)

There are many such persons in the world.

(世界上像这样的人多的是。)

(2)「such+a(n)+形容词+名词」和「so+形容词+a(n)+名词」几乎同义,但前者为比较口语化的表达方式:

such a long sermon

=so long a sermon

不过,如果名词为复数时,可以用像such long sermons,但通常不能说so long sermons。

用法

my不能与a, an, this, that, no等连用放在名词之后; of yours [his hers, ours, theirs]的道理也是如此,另外在此种结构中的mine, ours, his, etc.读来仍然要比前面的名词放轻些。
