以下是具体使用方法
（一）逗号的用法
1. 在并列连词（and, but, for, nor, or, yet ）前使用，用来连接句中的各分句。
In fact you do, but you may not remember me. （p17 全日制普通高级中学教科书（必修）英语第一册（下）Senior English for China Student’s Book 1B 以下标有页码未特别注明出处的皆出自本书）
2. 用逗号来分隔一系列单词、词组和从句。
In summer, people like to go sailing, swimming, horse-riding and rock-climbing in the mountains. （p42）
Red, pink, yellow and white roses filled the huge vases. （牛津现代高级英汉双解词典第6版 附录4 标点使用法）
In the summer of 1984, many trees died.
3. 逗号用来分隔与句子其他部分密切相连的简短插入语或旁白。（较长的，更为突兀的或复杂的插入成分的则用破折号或圆括号。）
Chemical fertilization，for example, helps to produce better crops, but is harmful to the environment. （p45-46）
4. 在并列形容词，即分别修饰同一个名词的形容词之间使用逗号，但也有的形容词之间不加逗号的。
For men, heroism was usually described as bravery and the active, successful overcoming of adversity.
5. 用逗号来分隔非限定性修饰语，即该修饰语对于句子的意义并非必不可少。非限定性修饰语与限定性修饰语的区别在于，它即使被省略，也不会改变句子的主要意思。
(1) 同位语
Ma De, former Party secretary of Suihua, in Northeast China’s Heilongjiang Province, was
charged with taking bribes worth 6.03 million yuan during his 10 years in various government positions.  (China Daily July29, 2005)
At the World Park, one of the largest theme parks in China, visitors can look at buildings, castles and statues from more than thirty countries. （P66）
注意：限定性同位语不用逗号隔开。
US President George W. Bush said on Wednesday that he looked forward to meeting President Hu Jintao later this year.  （China Daily July29, 2005）
(2) 从句
A brief comparison with the most famous chivalric drama, which was written fifteen years earlier, clarifies the uniqueness of Thon’s play.
与那部最著名的，完成于十五年前的骑士剧的简短比较，表明了索恩这部剧作的独特性。
When they discovered it about 1,000 years ago, they called it Aotearoa, which means “Lan
d of the long white cloud”. （P38）
(3) 副词短语和从句
Just like spoken language, body language varies from culture to culture. （P59）
He was born in Yidu, Shandong Province. （P48）
By the way, did you hear about Sue’s car?
Oh, so that’s where it was.
6. 逗号可以用在一个很长的引导性短语或从句后，逗号还可以用来分隔表示选择或对比关系的短语。
You can feel what it is like to live in space, walk on the ocean floor or ski with polar bears at the North Pole. （P69）
And remember, it is better to eat a potato than to be one. （P75）
7. 在以“月、日、年”为次序排列的日期间使用逗号。如果这种次序的日期出现在句子中间，则在“年”后也加上逗号。
Martin Luther King, Jr., was born on January 15, 1929, and died on April 4, 1968.
但在以“日、月、年”为次序排列的日期间，不使用逗号。
Martin Luther King, Jr., was born on 15 January 1929, and died on 4 April 1968.
