A Mr. Smith is waiting for you at the school gate.
He usually works eight hours a day.
You can try it a second time if you fail.
They are of an age./ Birds of a feather flocks together.
2）泛指某一类人或物，意为“任何一个，任一”
Eg:A square has four sides.
3）当物质名词具体化表示“一（类、阵、份）”等；抽象名词具体化为“……的人或者事”时
Eg:Green tea is a wonderful tea.
We don’t have much rain here, but last night we had a heavy rain.
Reading is a pleasure for me.
The meeting is a great success.
4）表示季节、月份、日期、三餐的名词，或表示世上独一无二的物体名词前有形容词修饰时
Eg:We have a every cold winter last year.
This happened on a rain Sunday towards the end of May.
We hope we can see a full moon tonight.
