不定冠词a (an)与数词one 同源，是"一个"的意思。a用于辅音音素前，一般读作[e]，而an则用于元音音素前，一般读做[en]。
1) 表示"一个"，意为one；指某人或某物，意为a certain。
A Mr. Ling is waiting for you.
2) 代表一类人或物
A knife is a tool for cutting with.
Mr. Smith is an engineer.
定冠词the与指示代词this，that同源，有"那（这）个"的意思，但较弱，可以和一个名词连用，来表示某个或某些特定的人或东西。
定冠词的用法:

Take the medicine. 把药吃了。

He bought a house. I've been to the house.
他买了幢房子。我去过那幢房子。

6）与复数名词连用，指整个群体：

We divide them into "definite" and "indefinite" like this:
DEFINITE = SURE = 明确的；一定的；肯定；有把握 - PARTICULAR = 特别的；详细的；独有的
INDEFINITE = NOT SURE = 不明确的，模糊的 - GENERAL = 普遍的
THE IS DEFINITE .. A & AN ARE INDEFINITE
Think of the sky at night. In the sky we see 1 moon and millions of stars. So normally we would say:
I saw the moon last night.
I saw a star last night.
I AM ANSWERING THE QUESTION YOU ASKED - MENTIONING "THE QUESTION" - YOUR QUESTION .
Have you got a book - ( ANY BOOK, NOT MENTIONED WHICH BOOKS )
I WANT TO EAT AN APPLE ... ( ANY APPLE - NOT A PARTICULAR APPLE )
