a/an不用在以下几种情况下:
A 复数名词之前:
a/an没有复数形式,所以a dog的复数是dogs,an egg的复数是eggs。
B 不可数名词之前(参见第13节):
C 三餐名称之前,但这些名称前加形容词时除外:
We have breakfast at eight.
我们8点钟吃早饭。
He gave us a good breakfast.
他请我们吃了一顿丰盛的早餐。
为了庆祝某事或特意为某人而举行的宴会之前要用冠词:
I was invited to dinner(at their house, in the ordinary way).
他们邀请我吃饭(在他们家吃便饭)。
但是说:
I was invited to a dinner given to welcome the new ambassador.
我被邀请参加欢迎新任大使的宴会。
