SAT语法易错点一：不连贯(Incoherence)

不连贯是指一个句子前言不对后语，或是结构上不畅通。这也是考生常犯的毛病。

例. The fresh water， it is the most important things of the earth. 剖析：The fresh water 与逗号后的it 不连贯。It 与things 在数方面不一致。 改为： Fresh water is the most important thing in the world.

SAT语法易错点二：词性误用(Misuse of Parts of Speech)

“词性误用”常表现为：介词当动词用;形容词当副词用;名词当动词用等。

例. None can negative the importance of money. 剖析：negative 系形容词，误作动词。 改为： None can deny the importance of money.

SAT语法易错点三：不间断句子(Run-on Sentences)

什么叫run-on sentence?请看下面的例句。

例. There are many ways we get to know the outside world. 剖析：这个句子包含了两层完整的意思：“There are many ways.” 以及“We get to know the outside world.”。简单地把它们连在一起就不妥当了。 改为： There are many ways for us to learn about the outside world. 或： There are many ways through which we can become acquainted with the outside world

SAT语法易错点四：不一致(Disagreements)

所谓不一致不光指主谓不一致，它还包括了数的不一致时态不一致及代词不一致等。

例. When one have money ，he can do what he want to . (人一旦有了钱，他就能想干什么就干什么。) 剖析：one是单数第三人称，因而本句的have应改为has ;同理，want应改为wants.本句是典型的主谓不一致。 改为： Once one has money ，he can do what he wants (to do)
