SAT语法真题中的句子改错非常类似于托福语法中的改错部分，即识别一个句子当中四个下划线里语法有错误的选项。不过SAT的语法与托福语法最大的区别在于，它还有第五个选项放在句后：NO ERROR，选择这个选项即认为这个句子没有语法错误。下面就为大家介绍一下SAT语法句子改错题常见错误。
常见SAT语法句子改错题错误1、代词指代错误：代词的性、数、格；比较特别考点是one 和you 不能相互指代。
例：Even with(A) a calculator, you must have a basic understanding(B)of mathematics if one expects(C) to solve complex problems correctly. No error(E)
分析：本题第一个代词是you,所以C错，应改为you expect。因为one和you 不能互相指代
常见SAT语法句子改错题错误2、主谓一致错误：常见错误类型，比较简单送分题。
例：The bright (A)fiberglass sculptures of Luis Jimenez has received (B)critical acclaim not only (C) in his home state, New Mexico, but also in (D)New York.
分析：本题显然主语sculptures是个复数而谓语动词has是个单数，所以主谓不一致，应该把B 改为have received
常见SAT语法句子改错题错误3、平行并列题型
例：Each time Caroline turns on her computers, she has(A) to enter a company code, then her initials, and then enters a password (B)before she can begin working(C). No error(D)
分析：B enters a password 前面出现了可爱的and，这个词决定了前后必须是平行并列，要求形式对称、概念对等、功能相同。所以前面也应该有第三人称单数动词+名词的结构和 enters a password并列，而前面出现的是her initials所以正确改法：去掉enters，这种考题在国内高考也经常考，这个考点因为出题频率特别的高。
常见SAT语法句子改错题错误4、词性混用题型
例：Although(A) the new device was the most clever (B) designed bird feeder that Ms.Rodriguez had ever owned (C), it could not keep squirrels from(D)stealing the birdseed. No error(E)
分析：正确答案是B 修饰动词designed 的用adv.cleverly
常见SAT语法句子改错题错误5、倒装题型
例： Air pollution caused by industrial fumes has been studied(A) for years, but(B) only recently has(C) the harmful effects of noise pollution become (D)known. No error(E)
分析：正确答案是C，本题考查的是倒装因为only +状语/状从要求引起倒装，而倒装后真的主语是 effects所以C应改为have
以上就是SAT语法句子改错题常见错误。总之IE题型是writing部分中最为简单的一种题型，考生只需认真看清楚我上边列出的题型分类，就可以轻松面对IE题型。
