下面為大家整理的是關于SAT基本語法原則的介紹，從英語語法本身的角度進行了分析，并針對SAT語法本身進行了對比，后面附有經典的習題整理。大家可以在備考的時候針對自己的實際情況進行準備和練習。

　　SAT語法一共分為3類，1是挑最優表達，2 是挑錯或是決定沒錯，3是文章改錯。這3類題目總體的難度都不大，對中國中學生來講，很容易上手。

　　在沒加試的情況下49題，經過一定程度的努力達到錯4個，加上寫作的大眾分8分，寫作就有望690了。

　　語法整體上是考察標準書面語的特征。這一塊的最大優點是你不需要記憶什么東西，什么規則詞組幾乎都不需要記憶，我們需要的是快速準確的干掉題目，而不是現場匹配各種知識點。

　　語法三塊有共性，有區別。就共性而言，它們要求的是識別和建構標準書面語。知識點的作用是有限的(尤其是對挑最優而言)。你需要關心的主要是幾個基本原則：

　　1、句基本完整性(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 thus closer to the Sun than Neptune is for 20 years out of every 230-year cycle, even though 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 last day scheduled to collect, workers at the automobile company are eligible for its severance 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 its severance package

　　(B) the last day they are scheduled to collect, workers are eligible for the automobile company's severance package

　　(C) their last scheduled day to collect, the automobile company offers its severance package to workers

　　(D) their last scheduled day in order to collect, the automobile company's severance package is available to workers

　　(E) the last day that they are scheduled to collect, the automobile company's severance package 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, it must now be determined by the airline's board of directors how the airline can both increase 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 both increase 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 both increase 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 airline increase 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 increase profits 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 increase profits 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 both increase ....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。

　　以上就是關于SAT基本語法原則的介紹，后面的習題都有詳細的解答。雖然很多人都說在語法項目上，中國考生是提高最快的，但是也不能掉以輕心，只有不斷的練習才能讓自己的語法知識點和SAT考試的出題點結合到一起。
