ÃÖ°í°ü¸®ÀÚ  |  14-04-21 18:48

3. Omission of a/an

a/an is omitted;

A. Before plural nouns.
a/an has no plural form. So the plural of a dog is dogs, and of an egg is eggs.

B.
Before uncountable nouns.

C.
Before names of meals, except when these are preceded by an adjective:
We have breakfast at eight.
He gave us a good breakfast.

The article is also used when it is a special meal given to celebrate something or in someone's honor:
I was invited to dinner (at their house, in the ordinary way) but
I was invited to a dinner given to welcome the new ambassador.

4. a/an and one

A. a/an and one (adjective)

1. When counting or measuring time, distance, weight etc. we can use either a/an or one for the singular:
£1 = a/one pound £1,000,000 = a/one million pounds
But note that in The rent is £100 a week the a before week is not replaceable by one.
In other types of statement a/an and one are not normally interchangeable, because one + noun normally means 'one only/not more than one' and a/an does not mean this:
A shotgun is no good. (It is the wrong sort of thing.)
One shotgun is no good. (I need two or three.)

2. Special uses of one

(a) one (adjective/pronoun) used with another/others:
One (boy) wanted to read, another /others wanted to watch TV.
One day he wanted his lunch early, another day he wanted it late.

(b) one can be used before day/week/month/year/summer/winter etc. or before the name of the day
or month to denote a particular time when something happened:
One night there was a terrible storm.
One winter the snow fell early.
One day a telegram arrived.

(c) one day can also be used to mean 'at some future date':
One day you'll be sorry you treated him so badly.
(Some day would also be possible.)

B. a/an and one (pronoun)
one is the pronoun equivalent of a/an:
Did you get a ticket? ~ Yes, I managed to get one.
The plural of one used in this way is some:
Did you get tickets? ~ Yes, I managed to get some.
