SAT語法句子改錯題解題步驟分享.

　　在SAT考試中， SAT語法句子改錯題是比較難的一種類型，下面我們就來具體看一下SAT語法句子改錯題的解題步驟。一般來說標準的解題順序可以分為如下幾步：

　　比如說有些句子在 TOEFL中是對的，但是在SAT語法里面就是錯誤的，因為它不夠簡潔有效。而且很多情況下SAT語法句子改錯不是讓你選擇一個完全正確的答案，而是讓你選擇一個最佳答案。可能五個選項都是錯誤的，但你就應該從這五個選項里面選擇一個錯誤相對來說最小的選項，它就是正確答案。所以大家在解題的時候切不可鉆牛角尖，應該從最優(yōu)性出發(fā)來尋找答案。可能你完全可以自己寫出一個選項來比答案更能夠符合題意，但是因為選項當中沒有，所以我們還是應該選擇一個最佳選項。

　　1.抓住明顯錯誤進行排除

　　首先大家需要尋找劃線部分是否有明顯的語法錯誤或邏輯錯誤，有的話馬上排除，再縱向?qū)ふ掖鸢?，把選項中沒有改正這些錯誤的都給排除掉。

　　例：The benits of exercise is as psychological as physical.

　　(A) is as psychological as physical

　　(B) are more than psychological, they’re physical

　　(C) are as much psychological as physical

　　(D) have psychological aspects as well as the physical ones

　　(E) is psychological in parts and physical as well

　　我們可以看出這道題目的主語是benits是復數(shù)，所以謂語動詞也應該用復數(shù)，但這里謂語動詞是單數(shù)，所以馬上把A排除掉，縱向?qū)ふ掖鸢?，發(fā)現(xiàn)E沒有改正錯誤，D選項錯誤的換了時態(tài)，所以都錯了。比較B和C選項，B選項的意思不對而且顯得比較多余累贅，所以答案選C.

　　2. 利用常考考點作為切入點

　　有時大家如果把一些?？伎键c給記住的話，就可以大大提高解題的速度。比如在SAT語法當中，劃線部分經(jīng)常出現(xiàn)的錯誤就是代詞指代不清和限定性從句的引導詞指代混亂。因此如果劃線部分出現(xiàn)了這兩類詞的話，在未發(fā)現(xiàn)明顯錯誤的時候，我們就應該以這兩類詞為切入點，通過確認其真實指代對象和語法指代對象是否一致來排除錯誤選項

　　例：The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and it is an important method of transportation.

　　(A) The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and it

　　(B) The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and

　　(C) Invented around the same time were the automobile, popularized by Henry Ford and the airplane, which the Wright brothers developed, and it

　　(D) The automobile popularized by Henry Ford. Was inverted around the same time as the Wright brothers developed the airplane and this is why it

　　(E) An invention around the same time as the Wright brothers developed the airplane, the automobile, popularized by Henry Ford, it

　　我們一起來分析一下這道題目，題干說由HF所推廣的汽車，與W兄弟所發(fā)明的飛機差不多在同一時間，它是一種重要的交通方法。大家發(fā)現(xiàn)劃線部分的最后一個詞it就犯了模棱兩可的錯誤，它既可以指代汽車，又可以指代飛機，所以A錯，同樣C, D, E也都有it，所以也不對。答案應該選擇B選項，把it給去掉了，這樣就避免了指代不明的錯誤。

　　3. 利用對稱性解題

　　與漢語一樣，英語在行文上也講究對稱性，而這一點在比較結(jié)構(gòu)和平行結(jié)構(gòu)中非常常見，即要求盡可能在語法功能上和形式結(jié)構(gòu)上表達一致。因此大家可以通過未劃線部分中的表達形式和語法功能來確定劃線部分中與之相對應部分的語法功能及表達形式，馬上排除錯誤選項。

　　例：Just as Ludwig van Beethoven composed scores of lasting musical works and the Bronte sisters wrote many enduring novels. so too did Vincent van Gogh paint numerous timeless masterpieces.

　　(A) so too did Vincent van Gogh paint numerous timeless masterpieces.

　　(B) Vincent van Gogh paints timeless masterpieces. and lots of them

　　(C) Vincent van Gogh’s bequest was to paint timeless masterpieces

　　(D) and to van Gogh then. were numerous masterpieces painted

　　(E) also like them van Gogh painted numerous timeless masterpieces

　　這兒明顯有固定搭配的對稱：Just as…so too…，意思是正如…也…，四個選項中只有A選項有平行對稱的so too，所以答案選A.

　　4. 對比選項，從選項中尋找答案

　　有時比較完了選項后，很難從已給信息中找出答案，這時我們可以比較剩下的選項，由選項中的不同來尋找答案。

　　例：In the eighteenth century, politics was thought to be an improper sphere for women, whose boycott of English goods was different than any protest the English had seen bore.

　　(A) whose boycott of English goods was different than any protest the English had seen bore

　　(B) whose boycotting English goods was different than any protest the English had seen bore

　　(C) whose boycott of English goods was different from any protest the English had seen bore

　　(D) whose boycott of English goods was different from any protest the English saw bore

　　(E) whose boycotting of English goods was different from any protest the English have seen bore

　　我們知道固定搭配應該是 be different from, 而不是be different than , 所以馬上把A和B排除掉。下一步就應該來對比剩下的三個選項，C和D用了名詞boycott，而E選項用了動名詞boycotting，在SAT語法當中有一條非常重要的原則，即名詞要優(yōu)先于動名詞，比方說同時出現(xiàn)了名詞和動名詞，就應該優(yōu)先備選名詞的選項。所以E錯。再把C和D進行比較，C用了過去完成時，D用了過去時，由題意應該是發(fā)生在18世紀以前，所以應該用過去完成時，所以答案選C.

　　5.找一個最佳的選項成為答案

　　在解題的最后有時候可能會發(fā)現(xiàn)五個選項都不是非常完美，那么這時你就應該選擇相對來說錯誤最少最為輕微的選項成為答案。

　　例：In exploring the rich variety of African artworks. the reason why one will note that certain patterns of meaning and usage occur again and again is nearly found in all world civilizations throughout most of history.

　　(A) In exploring the rich variety of African artworks. the reason why one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is nearly found in all world civilizations throughout most of history.

　　(B)In exploring the rich variety of African artworks. the reason why one will note that certain patterns of meaning and usage occur again and again is because this phenomenon is found in nearly all world civilizations throughout most of history.

　　(C)When you explore the rich variety of African artworks. the reason one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is found in nearly all world civilizations throughout most of history.

　　(D) When one explores the rich variety of African artworks. the reason one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is found in nearly all world civilizations throughout most of history.

　　(E) In exploring the rich variety of African artworks. the reason one will note that certain patterns of meaning and usage occur again and again is because found in nearly all world civilizations throughout history is this phenomenon of pattern repetition.

　　這道題目有些難度。這句話的意思是說在探索非洲藝術(shù)作品的富裕度時，人們將會注意到特殊模式的意思和習慣表達一再發(fā)生的原因是因為這種模式重復的現(xiàn)象能在幾乎所有世界文明中找到。

　　當大家具備了一定的 SAT語法基礎(chǔ)后就可以看出來原文有兩個錯誤。首先嚴格意義上，英語語法中規(guī)定reason和because是不能夠連用的，其次在劃線部分里有一處表達不夠正確，即this phenomenon of pattern repetition is nearly found in all world civilizations，它所表達的意思應該是這種模式重復的現(xiàn)象能在幾乎所有世界文明中找到，但劃線部分的意思變成了這種模式重復的現(xiàn)象幾乎被找到了在所有世界文明中。所以nearly的放置位置不對。這樣我們就可以縱向來尋找答案?？赐晡鍌€選項后大家可以發(fā)現(xiàn)沒有一個選項改正了reason和 because不能夠連用的這個錯誤，所以這個錯誤只能放著。再看其他選項，B, C, D, E把nearly的放置位置這個錯誤都給改正了，但是C和D引入了兩個新的錯誤，即one和you 不能同時出現(xiàn)，在SAT語法當中這種情況是不允許發(fā)生的，所以C和D都錯了。再來對比B和E選項，我們可以發(fā)現(xiàn)E中用了被動，found in nearly all world civilizations throughout history is this phenomenon of pattern repetition，使得句子結(jié)構(gòu)不夠清楚明了，所以答案選B。雖然說B還有reason和because不能夠連用的這個錯誤，但它卻是五個選項當中最佳的一個選項。因此我們講是找五個選項中找一個最佳的選項成為答案，而不是找一個完全正確的選項。

　　基本上大家走完這5步之后，就可以把正確答案給選出來了。

　　我們 在做SAT語法句子改錯題時，不僅要能判斷這個句子是否正確，而且要能判斷這個句子是否有效和簡潔。對于我們的能力，其實SAT語法句子改錯題的要求是比較高的，要獲得SAT語法句子改錯題高分一個最有效的辦法就是對SAT語法的真題進行反復的練習，大家只要持之以恒，就一定可以得到理想的分數(shù)。
