1、表示"一个",意为one;指某人或某物,意为a certain。如:
A Mr. Ling is waiting for you.

A knife is a tool for cutting with.
Mr. Smith is an engineer.

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。

the sun, the sky, the moon, the earth

如果有两个或两个以上的形容词修饰一个名词时,则由它们和被修饰的名词之间的密切程度而定,越密切的形容词越靠近名词。
如果几个形容词的密切程度差不多则按音节少的形容词放在前面,音节多的形容词放在后面。
