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(qū)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。下面小編就為大家介紹一下常見SAT語法句子改錯題錯誤。

　　1、代詞指代錯誤：代詞的性、數(shù)、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 abasic 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(yīng)改為you expect。因為one和you 不能互相指代

　　2、主謂一致錯誤：常見錯誤類型，比較簡單送分題。

　　例：The bright (A)fiberglass sculptures of Luis Jimenez has received (B)critical acclaim notonly (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(fù)數(shù)而謂語動詞has是個單數(shù)，所以主謂不一致，應(yīng)該把B 改為havereceived

　　3、平行并列題型

　　例：Each time Caroline turns on her computers, she has(A) to enter a company code, thenher 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(xiàn)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(yīng)該有第三人稱單數(shù)動詞+名詞的結(jié)構(gòu)和 enters a password并列，而前面出現(xiàn)的是her initials所以正確改法：去掉enters，這種考題在國內(nèi)高考也經(jīng)�？�，這個考點因為出題頻率特別的高。

　　4、詞性混用題型

　　例：Although(A) the new device was the most clever (B) designed bird feeder thatMs.Rodriguez had ever owned (C), it could not keep squirrels from(D)stealing the birdseed. Noerror(E)

　　分析：正確答案是B 修飾動詞designed 的用adv.cleverly

　　5、倒裝題型

　　例： Air pollution caused by industrial fumes has been studied(A) for years, but(B) onlyrecently 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(yīng)改為have

　　6、比較題型：

　　Just how(A) critical an improved balance of trade is to(B) a healthy economy has neverbeen (C)more clearer(D) than it is now. No error(E)

　　分析：本題考點很簡單C more clearer應(yīng)改為clearer

　　7、時態(tài)題型：重點考查主從句時態(tài)協(xié)調(diào)，重點考查的時態(tài)為常見時態(tài)

　　8、句子結(jié)構(gòu)題-非謂語動詞，從句等題型

　　9、固定搭配題型：請考生認真?zhèn)浜孟铝写钆?/strong>
