小编为大家分享的是
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. 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. 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：
一、举实例
思维短路，举实例!提出一个观点，举实例!提出一个方案，举实例!而且者也是我们揭示一个观点最好的方式，任何情况下，只要我们无法继续文章，不管三七二十一，尽管举例子!
In order to attract more customers, advertisers have adopted every possible stimulative factor in making ads, such as sound, light, colours, cartoon films and human performance. For instance, to advertise a certain food, advertisers will ask an actor or actress to sit at a table and devour the seemingly delicious food while they fime him or her.
更多句型：
To take …as an example, One example is…, Another example is…, for example
二、做比较
方法：写完一个要点，比较与之相似的;又写完一个要点，再比较与之相反的;
世界上没有同样的指纹，没有相同的树叶，文章亦同，只有通过比较，你才会发现二者的相同点(through comparison)和不同点(through contrast)。下面是一些短语：
相似的比较：
in comparison, likewise, similarly, in the same manner
相反的比较：
on the other hand, conversely, whereas, while, instead, nevertheless, in contrast, on the contrary, compared with …, …
三、换言之
没话说了，可以换一句话再说，让你的文章在多一些字，或者文邹邹地说，是让读者更充分的理解你的观点。
实际就是重复重复再重复!下面的句子实际上就三个字 I love you!
I am enthusiastic about you. That is to say, I love you.
I am wild about you. In other words, I have fallen in love with you.
或者上面我们举过的例子：
I cannot bear it.
可以用短语表达：I cannot put up with it.
因此可以这样说：I cannot bear it. That is to say, I cannot put up with it or I am fed up with it.
更多短语：
in more difficult language, in simpler words, put it more simply
He is having talks with the French foreign minister(外交部长). (=there is only one)
2. Superlative (最高级) 我们使用“the”在形容词最高级前面： 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.
