SAT语法中所谓平行结构就是由连词连接的多个部分语法上平行。即是达到形式，词性的一致，尽量保证时态一致的。

平行结构这类题的解题思路应该是：先发现平行标志词，然后找出应该平行的部分，最后从形式、词性和时态三个方面判断是否平行。下面列出了一些平行的结构

A,B and C

A and B

both A and B

between A and B

not only A but also B

either A or B

neither A nor B

A or B

not A but / rather B

A rather than / instead of B

not so much A as B

prefer A to B

prefer doing A to doing B

prefer to do A rather than do B

would rather do A than do B

例如这道错误的题：

To complete the music program, a student must present one vocal performance, one instrumental performance, and composing one original work.

我们发现正好是A,B and C的结构，前面都是用one…one…加名词的结构，所以我们应该将最后改为one original work.

Studies have suggested (A) that eating nuts—almonds in particular—might help to lower (B) blood cholesterol levels in humans and reducing (C) the risk of heart disease by protecting (D) the blood vessels. No error (E)

我们发现其中有and这个标志词，两个由help发出的动作，help to do sth.所以我们把C选项改为reduce.

Confident that she was fully prepared, Ellen decided to spend the night before the recital reading and relaxing but not to be practicing.

(A).but not to be practicing

(B).and not for practicing

(C).more than to practice

(D).rather than practicing

(E).rather than having practiced

我们注意到题中用and连接doing的形式，前面用到spend，我们知道spend sometime (in) doing sth.所以这两点都让我们选择doing的形式，只有D选项符合。

Without the invention of the compass, Magellan might not have sailed around the world, Lewis and Clark might not have traveled to Oregon, nor might de Soto’s search for the fabled cities of gold have occurred, either.

(A).nor might de Soto’s search for the fabled cities of gold have occurred, either

(B).and de Soto might not search for the fabled cities of gold

(C).and de Soto might not have searched for the fabled cities of gold

这道题也是非常明显是考察平行结构，前面的两个形式都是人加might have done的形式，所以这道题非常容易选出C选项。

另外，在平行结构中我们还需要注意其逻辑是表递进还是转折，and表递进，but表转折。还需注意一个特殊的搭配at once表示同时的意思，表示“即…又…”所以我们要用and表递进，例如这道题：

Acquaintances of Alexei have commented that he is at once annoying because of his unpredictability but his imagination is still a delight.

A. but his imagination is still a delight

B. although he is delightfully imaginative

C. and he is delightful in his imagination too

D. while being imaginative and they are delighted

E. and delightful because of his imagination

我们注意到at once后，直接在C选项和E选项中选择，题中用形容词+ because of的形式，后面也应当用形容词+ because of，只有E在形式是最平行。
