经过官方样题的公布之后我们发现新SAT语法更接近于现行SAT语法中的IP, 注重文章的内在逻辑性，注重文章结构的分析和文章逻辑的连贯性。但是新SAT语法的涵盖的知识点和SAT中的ISE和IS的知识点很相似，下面就针对平行机构来为大家讲解新SAT语法中平行结构是怎样考察的。
一.平行结构定义
所谓平行结构(parallelism)，就是把一个句子逻辑上应属于同一句法成分的并列事物用相同的结构来表达。在SAT语法考点中，就是要做到语法和词性的一直，只要形成平行结构的选项，在语法上都是最佳的。
二.平行结构考察形式
平行结构出现的时候有一些标志性词汇如下，也就是并列连词，所连接的成分一定要在语法和词性上保持一致。
并列连词：and, but, as well as, or, or else, both … and, neither … nor, either … or, not only … but (also), rather than, as…as等以及从属连词than可连接两个对等的词和对等的结构。
平行结构要求SAT语法平行部分具体满足哪些条件呢，以下仅供大家参考：
1.所连接的谓语形式必须一致
2.所连接的词或短语形式必须一致
3.连接的非谓语动词的形式必须一致
4.所连接的句子结构必须一致》》更多详情点击新SAT语法平行结构的讲解
三.SAT语法官方样题解析
下面是SAT语法官方样题解析，我们来通过这些真题来体会一下在新SAT语法中平行结构是怎样考察的。
A Life in Traffic
A subway system is expanded to provide service to a growing suburb. A bike‑sharing program is adopted to encourage nonmotorized transportation. [Q1] To alleviate rush hour traffic jams in a congested downtown area, stoplight timing is coordinated. When any one of these changes [Q2] occur, it is likely the result of careful analysis conducted by transportation planners.
Question 1.
Which choice best maintains the sentence pattern already established in the paragraph?
A. NO CHANGE (To alleviate rush hour traffic jams in a congested downtown area, stoplight timing is coordinated.)
B. Coordinating stoplight timing can help alleviate rush hour traffic jams in a congested downtown area.
C. Stoplight timing is coordinated to alleviate rush hour traffic jams in a congested downtown area.
D. In a congested downtown area, stoplight timing is coordinated to alleviate rush hour traffic jams.
题目：下列哪个选项能够和段落中的句型保持一致?
答案：C
解析：该题考查的就是句子结构必须一致，该句前两句是被动语态，因此根据平行结构，第三句也用被动语态，因此选项C是符合的。
下面我们再来看一道样题，也是对平行结构的考察。
The work of transportation planners generally includes evaluating current transportation needs, assessing the effectiveness of existing facilities, and improving those facilities or [Q3] they design new ones. Most transportation planners work in or near cities, [Q4] but some are employed in rural areas.
Question 3.
A. NO CHANGE (they design)
B. to design
C. designing
D. design
答案：C
解析：该题考查平行结构，根据前面的句式existing facilities, and improving those facilities选择的答案需要和or前面的improving平行，因此应该用designing。平行结构也是老SAT常考知识点，那这种考法就和老SAT考法一致了，虽然镶嵌在文章中但是考察点和以前一样。
以上就是给大家介绍的新SAT语法中平行结构是怎样考察的问题，希望可以给大家提供帮助，预祝大家取得理想的成绩。
