SAT語法例題解析

SAT很挑剔，不喜歡很多東西，不喜歡名詞+doing的結構，不喜歡代詞+doing 的結構，而且非常不喜歡 “something is why+從句”的結構。這些考生都需要牢記。一起來看看SAT語法例題解析。

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(jù)此瀏覽選項主語，干掉CDE,留下AB。再對比AB,發(fā)現(xiàn)內(nèi)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(jīng)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. 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(fā)出者：據(jù)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.

SAT語法原則——平行結構

SAT規(guī)定平行成分包括三個或以上的成分，平行的較后一部分前必須使用and，即and的使用要優(yōu)先于as well as

SAT中要牢記的典型的平行結構：

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的詞性必須是一致的

在SAT中，分號后面必須是一個完整的句子，除非是表達平行的時候，兩個以上的平行成分有時候會用分號連接。
