本文根据历年同学们在SAT语法复习中遇到的问题，归纳总结了以下几道经典例题以及SAT语法考点(独立主格、连词、平行结构、比较结构、句子结构)，为各位同学逐一进行详细解析，剖析SAT语法考试规律，考生可以据此进行针对性的备考，并结合练习来逐步掌握SAT语法考试，从而在2014年1月SAT语法考试中取得好成绩。

　　希望同学们找到文中所列举的题目，仔细研究明白，将这些题目的共性牢牢记住。具有共性的内容，也就是SAT语法考点的所在。

　　4. 比较结构

　　1) Built from 1609 to 1617 to rival (A) the Hagia Sophia, Istanbul’s Sultanahmet Mosque was celebrated (B) not so much for its architecture but because of (C) the exquisite blue tiles that adorned its (D) interior. No error (E) 09-1-6-27

　　此题考查not so…as…引导的比较结构，注意not so后的结构与as后的结构要有可比性，形式一致。C选项改成as for。

　　此考法典型题：08-5-6-11，OC3-10-2

　　2) Few issues of public policy are (A) as likely (B) to provoke widespread interest as that (C) involving possible danger to (D) the health or safety of children. No error (E) OG6-6-15

　　此题考查比较结构中的that、those用法，当比较双方没有可比性时，常用到that或those来改正。that指代之前出现过的单数名词，those指代复数名词。在此题中，比较的是issues of public policy与issues involving danger to，所以C选项的that改成those。

　　此类考法在13年5月亚洲题Section3的28题也出现。

　　3) The eerie songs of humpback whales, often lower in pitch and longer than birds, are intriguing to scientists partly because whales have no functional vocal cords. OG9-10-14

　　(A). The eerie songs of humpback whales, often lower in pitch and longer than birds,

　　(B). The eerie songs of humpback whales, which are often lower in pitch and last longer than birds,

　　(C). Humpback whales’ eerie songs, often pitched lower and longer than that of birds,

　　(D). The eerie songs of humpback whales, often lower in pitch and lasting longer than those of birds,

　　(E). Often being lower in pitch and lasting longer than birds, the eerie songs of humpback whales

　　此题考查比较结构可比性问题。比较结构标志词than后面是birds，前面是songs of whales，无可比性，借用those 指代songs，选D。

　　在做题过程中，遇到平行或比较的标志词后，可以先找标志词后的结构，再往前找平行或比较的另一方或几方，注意形式一致及内容相似。

　　此类题考的非常多，请参考：OG1-6-29，07-10-5-11、28，08-1-10-10，08-5-10-8，08-10-5-27，12-10-4-11,13-1-7-6、11
