下面来看一下SAT语法考试中的改错题分析，希望给大家的SAT备考带来帮助。
1.平行并列结构。两个以上的分句并列时，一般美国人爱用并列结构，这样的好处是使文章看起来工整。
判断方法：出现多个并列成分;出现比如from…to…等类似的经典介词组合。注意：并列结构使SAT很喜歡考察的内容!
Each time Caroline turns on her computer, she has to enter a company code, then her initials, and then enters a password before she can begin working. No error.
读句子，发现这个女人工作之前要干3件事：enter a company code, enters her initials, enters a password，这3个动作构成了并列。题干已经有提示：she has to enter a company code, then (enters)her initials, 所以剩下来的enters毫无疑问也应该省略即改成and then(enters)a password before she can begin working
A talented and versatile artist, Twyla Tharp has been a dancer, choreographer, and collaborated on various productions. No error.
还是并列结构，改成has been a dancer, choreographer, and collaborator.这样的句子就很整洁了。写作的时候可以用上的。
2.形容词与副词混淆。判断：看到以后注意就行了。
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，所以毫无疑问要将clever改成cleverly.
3.逻辑。双重否定。
4.同级比较。比如My pen in more beautiful than you. Pen跟you并不是同一类事物。
以上就是SAT语法考试中的改错题分解析，从名词、动词、固定搭配等方面进行了全面的阐述。同学们在平时做题时遇到这些问题，一定要认真地辨识。
