不管做什么事情，总有一些事情是我们知道的信息，在托福写作词汇中也有这么一群单词。天津新航道小编整理了一些，供大家参考学习。

        　　一 基本规律 (Basic rules)

        　　1. Indefinite article (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. Definite article (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. No articles (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. Fixed phrases ( 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 atthe end go to bed

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

        　　sixty kilometres an hour the next the other the other day

        　　the same

        　　二 经常发生问题的区域 (Areas that often cause problems)

        　　1. Jobs (工作)

        　　如果有许多人做这个工作我们用 a 或 an.：

        　　My husband is an architect. (=there are many architects)

        　　但是如果一个工作特别对应一个人，我们就要用“the”了：

        　　He is having talks with the French foreign minister(外交部长)。 (=there is only one)

        　　2. Superlative (最)

        　　我们使用“the”在形容词最前面：

        　　She is the best person for the job.

        　　3. Last and next

        　　有一些形容词如 “last” 和 “next ”同时可以用也可以不用定冠词“the”但是句意会发生变化

        　　I saw James last night. (=the one before this one)

        　　It is the last night of our holiday. (=the fanal one)

        　　I will see you next week.(=the one after this one)

        　　4. Institutions: school, prison, university, church, home, hospital

        　　和以上机构连用时我们不用定冠词“the”

        　　My sister had to stay in hospital overnight.

        　　然而，如果我们指的是这个建筑，我们就要用“the”

        　　Our flat is opposite the hospital.
