1.抓住明顯錯(cuò)誤進(jìn)行排除
首先大家需要尋找劃線部分是否有明顯的語法錯(cuò)誤或邏輯錯(cuò)誤，有的話馬上排除，再縱向?qū)ふ掖鸢福堰x項(xiàng)中沒有改正這些錯(cuò)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是復(fù)數(shù)，所以謂語動(dòng)詞也應(yīng)該用復(fù)數(shù)，但這里謂語動(dòng)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(cuò)誤，D選項(xiàng)錯(cuò)誤的換了時(shí)態(tài)，所以都錯(cuò)了。比較B和C選項(xiàng)，B選項(xiàng)的意思不對(duì)而且顯得比較多余累贅，所以答案選C.

2. 利用?？伎键c(diǎn)作為切入點(diǎn)

有時(shí)大家如果把一些常考考點(diǎn)給記住的話，就可以大大提高解題的速度。比如在SAT語法當(dāng)中，劃線部分經(jīng)常出現(xiàn)的錯(cuò)誤就是代詞指代不清和限定性從句的引導(dǎo)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(cuò)誤的時(shí)候，我們就應(yīng)該以這兩類詞為切入點(diǎn)，通過確認(rèn)其真實(shí)指代對(duì)象和語法指代對(duì)象是否一致來排除錯(cuò)誤選項(xiàng)。

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(jī)差不多在同一時(shí)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(gè)詞it就犯了模棱兩可的錯(cuò)誤，它既可以指代汽車，又可以指代飛機(jī)，所以A錯(cuò)，同樣C, D, E也都有it，所以也不對(duì)。答案應(yīng)該選擇B選項(xiàng)，把it給去掉了，這樣就避免了指代不明的錯(cuò)誤。
