在AEIS語法考試中經�？嫉囊粋�考點就是A, B, and C平行結構，幾乎每套題都會有這一考點，比如說： not only…but also…,either …or…, neither…nor…, as…as…, not so much …as…,both…and….等等。下面AEIS培訓基地小編來為大家詳細介紹AEIS語法考試部分之平行結構考點，希望對大家的語法考試有所幫助。

　　AEIS語法平行結構考點有兩種基本形式：

　　一：A, B, and C, 可以是詞的并列，可以是短語的并列，也可以是句子的并列：

　　Example One:

　　Employees are happier, healthier, and more productive when they work in anenvironment with natural light. (三個形容詞的并列)

　　Example Two:Each time Caroline turns on her computers, she has to enter acompany code, then her initials, and a password before she can begin working.(三個名詞短語的并列)

　　Example Three:The kids are running, the adolescents are chatting, and theseniors are walking. (三個句子的并列)

　　

 

　　二：A and B，可以是詞或者短語的并列，也可以是句子的并列：

　　Example One:

　　Barbers in Europe during the Middle Ages had the special functions ofperforming surgery and pulling teeth. (兩個動詞短語的并列)

　　Example Two:

　　Tigers and lions may be identical in size, but the tiger is the fierceranimal and the lion is the stronger one.(兩個句子的并列)
