雅思写作考试部分跟雅思口语考试部分其实都是差不多的，都在雅思考试中占有的相当重要的位置，所以大家想要自己的雅思考试分数更高的话就一定要备考好这些小部分，当然最重要的还是雅思词汇的积累了。
下面留学360专家就来介绍分享一下雅思写作考试以及雅思口语考试部分的雅思词汇的积累以及逗号的运用。
雅思写作7分在这一项要达到has good control of grammar and punctuation but may make a few errors。6分在这一项的评分标准是make some errors in grammar and punctuation but they rarely reduce communication。5分在这一项的评分标准是may make frequent grammatical errors and punctuation may be faulty。
中国大部分考生在参加雅思写作考试的时候知道英语的句号是实心圆点而不是空心点; 另外，参加过英语学习的考生能初步掌握英语写作中不能出现逗号一逗到底的这种段落和文章。但是仅仅知道这些还是不够的，在雅思写作中逗号(comma)用的次数是最多的，毋庸置疑逗号(comma)的功能也是最多的，如果考生能准确掌握逗号(comma)的作用及用法，雅思写作能提高0.5到1分。现在和大家分享一下逗号(comma)在雅思写作中的灵活准确运用。
1.A comma is used in a compound sentence before the conjunction or connective (and, but, or, for, so, nor, or yet)
a. We were tired, and we decided to have a rest. (and并列复合句用逗号)
b. Journalists have long been regarded as the conscience of society, but today many of them find it increasingly difficult to present factual news stories. (but并列复合句用逗号)
2.A comma is used after an adverbial clause or phrase before the subject of the sentence or in the middle of the sentence.
a. In the ancient palace, they saw the throne where emperors used to sit. (状语短语在句子中用逗号)
b. At lease for the foreseeable future, books will continue to be easier on the eyes. (状语短语在句子中用逗号)
3.The comma is often omitted when an adverbial element follows the main clause.
a. I was trying to reach her by phone when she walked into my office. (When引导的状语从句逗号可以省略)
b. Eating a lot of junk food may cause illnesses when we get older. (When引导的状语从句逗号可以省略)
c. When we get older, eating a lot of junk food may cause illnesses. (When引导的状语从句逗号没有省略)
4.Commas are used to separate a series of words or phrases having the same function in the sentence.
a. She buys bread, butter, vegetables, and many other things from this supermarket. (并列的名词之间用逗号)
b. Many modern cities are overcrowded with residential, commercial and recreational buildings.(并列的形容词之间用逗号)
5. Nonrestrictive clauses and phrases are set off by commas.
a. He had to leave his hometown, where he had lived ever since he was born.(非限制性定语从句用逗号)
