SAT語法真題中的句子改錯非常類似于托福語法中的改錯部分，即識別一個句子當中四個下劃線里語法有錯誤的選項。不過SAT的語法與托福語法最大的區別在于，它還有第五個選項放在句后：NO ERROR，選擇這個選項即認為這個句子沒有語法錯誤。下面就為大家介紹一下常見SAT語法句子改錯題錯誤。

　　常見SAT語法句子改錯題錯誤1、代詞指代錯誤：代詞的性、數、格;比較特別考點是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：本題第一個代詞是you,所以C錯，應改為you expect。因為one和you 不能互相指代

　　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：本題顯然主語sculptures是個復數而謂語動詞has是個單數，所以主謂不一致，應該把B 改為have received

　　常見SAT語法句子改錯題錯誤3、平行并列題型

　　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 前面出現了可愛的and，這個詞決定了前后必須是平行并列，要求形式對稱、概念對等、功能相同。所以前面也應該有第三人稱單數動詞+名詞的結構和 enters a password并列，而前面出現的是her initials所以正確改法：去掉enters，這種考題在國內高考也經常考，這個考點因為出題頻率特別的高。

　　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：正確答案是B 修飾動詞designed 的用adv.cleverly

　　常見SAT語法句子改錯題錯誤5、倒裝題型

　　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：正確答案是C，本題考查的是倒裝因為only +狀語/狀從要求引起倒裝，而倒裝后真的主語是 effects所以C應改為have

　　常見SAT語法句子改錯題錯誤6、比較題型：

　　Just how(A) critical an improved balance of trade is to(B) a healthy economy has never been (C)more clearer(D) than it is now. No error(E)

　　分析：本題考點很簡單C more clearer應改為clearer

　　常見SAT語法句子改錯題錯誤7、時態題型：重點考查主從句時態協調，重點考查的時態為常見時態

　　常見SAT語法句子改錯題錯誤8、句子結構題-非謂語動詞，從句等題型

　　常見SAT語法句子改錯題錯誤9、固定搭配題型：請考生認真備好下列搭配

　　preoccupation with take advantage of=make use of contrast with be involved in think about use sth to do threaten to do take pride in result in/from prefer to protest against inconsistent with manage to do listen to neither nor either or be more likely to do 等短語，這些短語都是在考試過程中高頻出現的短語。

　　以上就是常見SAT語法句子改錯題錯誤的總結。總之，IE題型是writing部分中最為簡單的一種題型，考生只需認真看清楚我上邊列出的題型分類，就可以輕松面對IE題型。
