三、用不定冠词的场合
若breakfast, lunch, supper受到描绘性定语的修饰，则其前通常要用不定冠词。如：
We had a working lunch. 我们吃了一顿工作午餐。
We had a very late lunch. 我们很晚才吃午饭。
That was quite a decent lunch. 那顿午餐相当不错。
He takes a packed lunch to work. 他带(盒装)午饭上班。(from www.hxen.com)
After a quick breakfast, he hurried to the station. 匆匆忙忙吃完早餐，他就赶到车站去了。
I’ve got out of the habit of having a cooked breakfast. 我已不再保持早餐吃热食的习惯。
We had a quick lunch and finished up with a cup of coffee. 我们匆忙吃了午饭，最后又喝了一杯咖啡。
【知识拓展】
1. 有时可以有自己的修饰语：此时通常是指所吃的东西。如：
She doesn’t eat much breakfast. 她早点吃得不多。
She always eats very little supper. 她晚饭总是吃得很少。
Take her some breakfast on a tray. 用托盘给她送些早点。
注：有时也可不直接用 much, little 等修饰，而换用其他表达。如：
She never eats much for breakfast. 她早点从不多吃。(from www.hxen.com)
2. 有时可以用复数形式：此时通常是指不同种类或不同人所用的早餐、中餐或晚餐。如：
We serve hot and cold lunches. 我处供应冷热午餐。
Does this pub provide lunches? 这家酒馆供应午餐吗?
