SAT语法例题解析

SAT很挑剔，不喜欢很多东西，不喜欢名词+doing的结构，不喜欢代词+doing 的结构，而且非常不喜欢 “something is why+从句”的结构。这些考生都需要牢记。一起来看看SAT语法例题解析。

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. 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 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 bothincrease ....and also how, 错。选D.

SAT语法原则——平行结构

SAT规定平行成分包括三个或以上的成分，平行的较后一部分前必须使用and，即and的使用要优先于as well as

SAT中要牢记的典型的平行结构：

Not only A but also B not A but B

Both A and B neither A nor B

Either A or B from A to B

注意：A和B的词性必须是一致的

在SAT中，分号后面必须是一个完整的句子，除非是表达平行的时候，两个以上的平行成分有时候会用分号连接。
