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，再縱向尋找答案，把選項中沒有改正這些錯誤的都給排除掉。
例：The benefits 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benefits是複數，所以謂語動詞也應該用複數，但這裏謂語動詞是單數，所以馬上把A排除掉，縱向尋找答案，發現E沒有改正錯誤，D選項錯誤的換了時態，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餘累贅，所以答案選C.
2. 利用常考考點作爲切入點
有時大家如果把一些常考考點給記住的話，就可以大大提高解題的速度。比如在SAT語法當中，劃線部分經常出現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了這兩類詞的.話，在未發現明顯錯誤的時候，我們就應該以這兩類詞爲切入點，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，題幹說由HF所推廣的汽車，與W兄弟所發明的飛機差不多在同一時間，它是一種重要的交通方法。大家發現劃線部分的最後一個詞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。
