【AEIS考试实战讲解】AEIS语法考试部分之平行结构考点

　　在AEIS语法考试中经常考的一个考点就是A, B, and C平行结构，几乎每套题都会有这一考点，比如说： not only…but also…, either …or…, neither…nor…, as…as…, not so much …as…, both…and….等等。下面AEIS中国培训基地小编来为大家详细介绍AEIS语法考试部分之平行结构考点，希望对大家的语法考试有所帮助。

　　AEIS语法平行结构考点有两种基本形式：

　　一：A, B, and C, 可以是词的并列，可以是短语的并列，也可以是句子的并列：

　　Example One:

　　Employees are happier, healthier, and more productive when they work in an environment with natural light. (三个形容词的并列)

　　Example Two:Each time Caroline turns on her computers, she has to enter a company code, then her initials, and a password before she can begin working. (三个名词短语的并列)

　　Example Three:The kids are running, the adolescents are chatting, and the seniors are walking. (三个句子的并列)

　　二：A and B，可以是词或者短语的并列，也可以是句子的并列：

　　Example One:

　　Barbers in Europe during the Middle Ages had the special functions of performing surgery and pulling teeth. (两个动词短语的并列)

　　Example Two:

　　Tigers and lions may be identical in size, but the tiger is the fiercer animal and the lion is the stronger one.(两个句子的并列)

　　1. Yogurt manufacturers, food scientists; and government officials are also working together to develop additional solutions for reusing whey.

　　A. NO CHANGE

　　B. scientists: and

　　C. scientists, and

　　D. scientists, and,

　　答案解析：划线部分有信号词 “and”, 读完句子之后发现主语是三个不同的人群：yogurt manufacturers, food scientists, and government officials, 恰恰是A，B，and C 的结构，所以答案选C。

　　B. containing

　　C. contains

　　D. will contain

　　答案解析：划线部分前面有信号词 “and”, 读完句子之后发现“and”前面有两个逗号，秒想到A，B，and C 的结构，当看到句子中的“is”and“serves”两个动词的时候，果断选C，正好可以构成三个动词词组的并列。

　　3. As a result, librarians must now be proficient curators of electronic information, compiling, catalog, and updating these collections.
