下面为大家整理的是关于SAT基本语法原则的介绍，从英语语法本身的角度进行了分析，并针对SAT语法本身进行了对比，后面附有经典的习题整理。大家可以在备考的时候针对自己的实际情况进行准备和练习。

　　SAT语法一共分为3类，1是挑最优表达，2 是挑错或是决定没错，3是文章改错。这3类题目总体的难度都不大，对中国中学生来讲，很容易上手。

　　在没加试的情况下49题，经过一定程度的努力达到错4个，加上写作的大众分8分，写作就有望690了。

　　语法整体上是考察标准书面语的特征。这一块的最大优点是你不需要记忆什么东西，什么规则词组几乎都不需要记忆，我们需要的是快速准确的干掉题目，而不是现场匹配各种知识点。

　　语法三块有共性，有区别。就共性而言，它们要求的是识别和建构标准书面语。知识点的作用是有限的(尤其是对挑最优而言)。你需要关心的主要是几个基本原则：

　　1、句基本完整性(必须是完整句)

　　2、一致性(语意与结构)

　　3、意思本身的精确性(学会把意思读准读出来!)

　　4、依据上面的标准扔错的剩对的。

　　用几个例子来说明：

　　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：句子开头的“不像其他行星”是个一致性标志，意味着主句主语必须是行星的平行词。据此浏览选项主语，干掉CDE,留下AB。再对比AB,发现内部都有比较，这也是一致性标志，那再看谁更烂，扔掉。A说P有个什么样的轨道，轨道更接近太阳，比N.意思是轨道和N比，已经不一致，干掉。B 没法不对了，否则就没有答案了。要不再看一眼。B说：P有什么样的轨道因此P更接近太阳比N.两行星比，对了。答案还是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

　　句开头的“不像大多数分手费”说明句子主语也该是分手费的类似概念，据此浏览划线内主句主语，干掉ABC,留下DE.DE的区别很小，那就认真读意思：D说，带到最后一天以便拿那笔钱;E说，最后一天是他们准备要收的：拜托，E讲他们不是拿钱，而是拿最后一天!区别出来了没有?选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 开头，按照一致性原则，主句主语 应该是动作发出者：据此干掉前两个。后三个都有BOTH... AND...一致性标志那看谁更一致：C说BOTH HOW....AND COMPETE，错;D没看出错，E both increase ....and also how, 错。选D.

　　注意：实际考试时句子(含划线部分)可能很长，因此将选项逐一读完很费时间，因此建议大家关注一致性的落脚点，据此用长项竖读的方式，快速干掉违反一致性原则的选项。

　　以上就是关于SAT基本语法原则的介绍，后面的习题都有详细的解答。虽然很多人都说在语法项目上，中国考生是提高最快的，但是也不能掉以轻心，只有不断的练习才能让自己的语法知识点和SAT考试的出题点结合到一起。
