摘要：就SAT語法共性而言，它們要求的是識別和構建標準書面語。本文通過例題解析，來介紹解答SAT語法題的重要原則。
SAT語法你需要關心的主要是幾個基本原則：1、句子基本完整性(必須是完整句)；2、一致性(語意與結構)；3、意思本身的精確性(學會把意思讀準讀出來)；4、依據上面的標準扔錯的剩對的。
用幾個例子來說明：
1 Unlike the other?major?planets, Pluto has a highly eccentric orbit, which is thuscloser to the Sun than Neptune is for 20 years out of every 230
year cycle, eventhough it is commonly described as the remotest planet in the solar system.
(A) Pluto has a highly eccentric orbit, which is thus closer to the Sun than Neptune is
(B) Pluto has a highly eccentric orbit and is thus closer to the Sun than Neptune is
(C) Pluto's orbit is highly eccentric and is thus closer to the Sun than Neptune
(D) the orbit of Pluto is highly eccentric and thus closer to the Sun than Neptune
(E) the orbit of Pluto is highly eccentric, thus closer to the Sun than Neptune is
解答 ：句子開頭的“不像其他行星”是個一致性標志，意味著主句主語必須是行星的平行詞。據此瀏覽選項主語，干掉CDE,留下AB。再對比AB,發現內部都有比較，這也是一致性標志，那再看誰更爛，扔掉。A說P有個什么樣的軌道，軌道更接近太陽，比N.意思是軌道和N比，已經不一致，干掉。B 沒法不對了，否則就沒有答案了。要不再看一眼。B說：P有什么樣的軌道因此P更接近太陽比N.兩行星比，對了。答案還是B.
2. Unlike most severance packages, which require workers to stay until the lastday scheduled to collect, workers at the automobile company are eligible for itsseverance package even if they find a new job before they are terminated.
(A) the last day scheduled to collect, workers at the automobile company are eligible for itsseverance package
(B) the last day they are scheduled to collect, workers are eligible for the automobilecompany's severance package
(C) their last scheduled day to collect, the automobile company offers its severancepackage to workers
(D) their last scheduled day in order to collect, the automobile company's severancepackage is available to workers
(E) the last day that they are scheduled to collect, the automobile company's severancepackage is available to workers
句開頭的“不像大多數分手費”說明句子主語也該是分手費的類似概念，據此瀏覽劃線內主句主語，干掉ABC,留下DE.DE的區別很小，那就認真讀意思：D說，帶到最后一天以便拿那筆錢;E說，最后一天是他們準備要收的：拜托，E講他們不是拿錢，而是拿最后一天!區別出來了沒有?選D。
3. Having finally reached a tentative labor agreement with its company's pilots, itmust now be determined by the airline's board of directors how the airline can bothincrease profits and compete more?effectively for customers than they did in the past.
(A) it must now be determined by the airline's board of directors how the airline can bothincrease profits and compete more?effectively for customers than they did in the past
(B) it must now be determined by the airline's board of directors how the airline can bothincrease profits and must compete more effectively than in the past for customers
(C) the airline's board of directors must now determine both how to make the airlineincrease profits and compete more effectively for customers than they did in the past
(D) the airline's board of directors must now determine how the airline can both increaseprofits and compete more effectively for customers than it did in the past
(E) the airline's board of directors must now determine how the airline can both increaseprofits and also how to make it compete more effectively than in the past for customers
解答： 用HAVING 開頭，按照一致性原則，主句主語 應該是動作發出者：據此干掉前兩個。后三個都有BOTH... AND...一致性標志那看誰更一致：C說BOTH HOW....AND COMPETE，錯;D沒看出錯，E bothincrease ....and also how, 錯。選D.
注意： 實際考試時句子(含劃線部分)可能很長，因此將選項逐一讀完很費時間，因此建議大家關注一致性的落腳點，據此用長項豎讀的方式，快速干掉違反一致性原則的選項。
