我们都知道新SAT语法中除了题型的变革之外，考点也发生了变化，保留了之前的改错和改进句子题的考点，还增加了一些符号，逻辑关系的考察，今天就是针对符号来给大家讲解一下，来给大家介绍的是新SAT语法中逗号是如何考察的。
一.新SAT语法中逗号的用法
下面给大家介绍一下新SAT语法中逗号的用法，大家一定要了解，这样才能更好的在考试中灵活运用。
1.逗号常考的用法就是连接并列成分。
逗号通常使用在三者或以上的平行中，逗号在前几个平行成分间使用进行区分，在最后一个平行成分前使用and或其他conjunction(连接词)连接，表示平行关系结束。
2.逗号用来分隔插入语
插入语部分一般情况下是句子主干以外的独立成分，用于补充信息、解释说明或提供例证。在句子中用逗号、破折号、或者括号隔开。主要分为非限定性定语从句、介词短语、动名词短语、同位语等等。
3.分隔状语从句等副词属性的成分
副词性成分在句子中可以单独放置在句首或句子中间，包括状语从句、副词短语、独立结构等等，此时需要正确使用逗号将其与主干句隔离开来。》》新SAT语法中逗号的多种用法
