2016年3月, 新 SAT 语法以崭新的形式(Writing and Language Test，即写作语言测试)出现在 Evidence-Based Reading and Writing 这部分里。要求考生在以段落为语境的基础上，不仅从文章的发展结构方面修改，而且从以书面英语为标准审查段落的语言方面修改。跟旧 SAT 不一样的是，新的 SAT 加入了一个全新的语法点——标点符号。其中逗号的考点是最常见的，那么下面百利天下小编为大家介绍的就是新SAT语法考点中的逗号使用。
1. 逗号：用于连接一个句子中的并列成分
例句：The main products of the district are wool, cotton, timber and tung-oil.

必记公式：a and b(两个名词短语平行不用逗号)
a, b, and c
a, b, c, and d
