1、主谓一致。尤其用于倒装时，比如therebe句型或地点状语至于句首，要找到真正的主语;有插入语时，要勇敢的抛弃非中心部分，找到真正的主语;主谓一致还会出现在一些固定用法中，但是一般比较简单，比如neither nor或者not only but also等等。
2、逻辑主语，当分词或者形容词放在句首，一定要考虑它的主语问题。
3、时态的混用，常出的错误是：have+过去式，过去完成时和一般过去式混用，现在完成时和一般过去式的混用。所以这方面比较弱的话建议大家听一些有经验的老师做的SAT语法讲解。
4、名词和代词，常常名词单复数混淆，男女混淆，主格宾格混淆;也会在their、it和they之间指代不明;关于指代，跨段之间不能指代，it不能指代整个句子，只能指代一个名词或动作，one和they不能相互指代，one和you也不能相互指代;this不能单独充当主语和宾语。
5、同类比较，只有同类的东西才能用于as well as和than句型。
6、adj和adv的混用：adj修饰名词，adv可以修饰除名词外的大部分词。Adj和adv两者之间用比较级，三者或三者以上用最高级。
