SAT考试想要拿高分数语阅词一个都不能少，今天小编分享的是SAT语法知识点简析希望可以帮助到大家，在备考的烤鸭们可以仔细看看。
一、动词。主谓一致的单复数问题
时态错误，过去式的单词错误。时态错误主要发生在主句和从句的时态不一致。有些不规则动词的过去式用错，比如常见的hang、rise等等，当然也有drove写成drived的。
看到动词要反应是单复数、时态问题，都沒有就考虑词汇用错问题。
Neither…or…; Either… or…后面的谓语跟第二个主语保持一致。
…along with…; …as well as…; …in addition to…与个主语保持一致。
Both…and…用复数形态。
二、形容词与副词混淆
Although the new device was the most clever designed bird feeder that Ms. Rodriguez had ever owned, it could not keep squirrels from stealing the birdseed. No error.
用Word一看就知道哪里有错了……clever designed里头，designed是动词，clever是修饰designed的。但是修饰动词的只有副词，毫无疑问将clever改成cleverly.
三、固定搭配，动词与介词
如look at连词搭配，比如either…or…看到有介词划线就注意一下。这种题目平时积累很重要!背固定搭配的时候一定要注意介词与不定式的区分问题!比如look forward to，其中to是介词，后面的动词要使用动名词形式。
四、代词主格与宾格
文中出现的多个代词不一致，代词是用来指代的，看到代词马上回头寻找其指代对象。
To become a world figure-skating champion like Kristi Yamaguchi, one must be so dedicated that you will practice six hours a day. No error.
这句话的问题在于代词使用不一致。请看one must be so dedicated that you will practice six hours a day，前面用的代词是one，但是后文使用的是you，再理解句意，不难发现两个代词其实是在指代同一个人。所以应该把you改成one.
五、对比主语跟宾语
主语跟宾语的单复数形式必须相同。也可能会根据谓语或者定语进行判断。下面是例题。
No matter when they came from or what their previous lifestyle is, the refugees were grateful for having been granted political asylum in the United States. No error.
what their previous lifestyle is这段话， their跟lifestyle的单复数不同，当然还有后面的is也一起错了。应该改成lifestyles are.
