经过对于SATog语法真题的考点整理，小编发现语法中的平行结构考点在任意一套真题中都频繁出现，考生务必要引起重视，今天小编就来给大家分享一下SAT语法平行结构备考经验。
在SAT语法中所谓平行结构(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。它要求处于并列关系的句子与句子之间，句子内部并列的成分之间采取同类语法形式来表达，以达到句意明晰、用词节省、加强语气而且能起篇章纽带作用。下面我们来看看集中常见的平行结构：
1. 比较级结构中的平行
In a recent year, more tourists from the United States visited museums in Great Britain than Canada.
(A)Canada
(B)Canada did
(C)compared to Canada's
(D)Canadian ones
(E)in Canada
句意：近几年，来参观大不列颠博物馆的美国游客要多于加拿大游客。
解析：E，这里考察比较级的平行结构，与前面的in Great Britain是对应的
2. and连接的两个成分的平行
The main reasons students give for failing to participate in the political process is that they
have demanding assignments and work at part-time jobs.
(A)is that they have demanding assignments and work at
(B)are demanding assignments and they work at
(C)are that they have demanding assignments and that they work at
(D)is having demanding assignments and having to work at
(E)are demanding assignments, in addition to working at
句意：学生们对于没有参加政治改进给出的原因是他们被分配了任务在做兼职。
解析：C，AD主谓不一致， B demanding assignments and they work at这两个原因不是平行结构，E平行结构错误。
3. 宾语结构的平行
Major risk factors for cardiovascular disease include high blood pressure, high blood cholesterol, smoking, and to be physically inactive.
(A) include high blood pressure, high blood cholesterol, smoking, and to be physically inactive
(B) include high blood pressure, high blood cholesterol, smoking, and
physical inactivity
(C) include high blood pressure, blood cholesterol, smoking, and being physically inactive
(D) Includes high blood pressure, high blood cholesterol, smoking, and to be physically inactive
(E) Includes high blood pressure, high blood cholesterol, smoking, and being physically inactive
句意：引发心血管疾病的因素有很多主要有高血压，胆固醇，吸烟，缺乏运动。
解析：B题干错误比较明显，谓语include后面分为四个平行的宾语，high blood pressure high blood cholesterol, smoking, and to be physically inactive，前三个部分均为名词短语，最后一个部分为动词不定式，因此在成分上与前面三个不平行。因此排除A,C,D,E(同时D,E中出现主谓不一致的情况)，B为正确选项。
