在SAT语法的改词，改句和改段三种类型的题目当中，改段是最耗时的，当然改段的题目数量不多，今天小站君主要讲解如何快速解答改词和改句两种题型和大家进行探讨。
1.系统学习语法知识点。
这是快速解题的基础，如果没有经过系统的培训，不了解什么是平行结构这些语法知识点，下面的解题方法都是没有意义的。
2.直接从划线部分定位考点。
考试时间紧的境况下，把句子从头读到尾会导致做题速度慢，所以可以直接从划线部分下手。 如下面这道真题：
The most engaging feature of the election was undoubtedly the candidates' debate with foreign policy issues. No error
看到B选项中的was马上要思考到三个考点：动词时态，主谓一致和动词语态(主动和被动)。如果都从这三个角度都没有问题再看下一个选项。
3.改句中对比剩余选项。
用划线部分的考点排除一些选项后，对比剩余的几个选项，先对比开头和结尾，快速了解选项之间的不同。比如下面这道题：
If one looks at the sky from a dark site, far from brightly lit urban areas, you can see the Milky Way arching over you.
(A) If one looks
(B) To look
(C) If you look
(D) When someone looks
(E) Look
一比较五个选项的结尾就知道要么是look,在剩余3个选项中选出正确答案，要么是looks,在剩余的两个选项中选出正确答案。当选项比较长时，这是非常有效的快速解题方法。
4.优先考虑最短的选项。
因为最短的选项通常符合简洁原则，所以通过划线部分排除几个选项后，在剩余选项中可以先去看最短的选项。如下面这道题：
The programmers always talked of having too much to do, but in truth they had a lesser amount of work to do than their colleagues.
(A) they had a lesser amount of work to do
(B) their work was the least among
(C) they were having less work to do than
(D) the amount of work they had to do was the least of
(E) they had less work to do than
