冠词虽小，但很多烤鸭在托福写作中却经常出错，导致失分。下面环球教育(原环球教育)的托福老师就来告诉大家冠词使用的基本规律和技巧，希望同学们以后不要在冠词上丢分了。

　　1. 不定冠词

　　我们用“a，an”当我们不知道他是诸多人或事中的哪一个：

　　* is one of many. (是许多个中的一个)

　　He is an artist.(=there are many artists)

　　* is not unique. (不是唯一的)

　　I have just bought a book

　　* has not been mentioned before. (之前没有提到过)

　　There was a new student in class today.

　　2. 定冠词

　　我们用“the”当我们知道他是诸多人或事中的哪一个：

　　* is unique (or unique in that context) (是唯一的)

　　The Australian Prime Minister. (=there is only one)

I looked inside, the engine was in a terrible state. (=there is only one engine, in this case)

　　* has been mentioned before. (之前提到过)

　　The man gave me a ticket. I looked at it, and saw that the ticket was a single.

　　* is defined by the phrase which follows it. (要被接下来的短语详细说明)

　　What is the new student's name?

　　3. 无冠词

　　我们不用冠词当我们普遍地提及事物的时候：

　　* using plural or uncountable nouns (在使用复数或不可数名词时)

　　Do you like sport?

　　* with the names of people or places, but there are many exceptions (人名和地名的时候不用冠词，但是地名有许多例外，下文一一介绍)

　　He is Professor Jones

　　4. 固定短语

　　有许多固定搭配需要用或者不用冠词，我们应该来单独学习，他们包括：

　　a few at home at work at the beginning at the end go to bed

　　go to the cinemas, shops, station in the world once a week

　　sixty kilometers an hour the next the other the other day

　　the same
