For Example, [a sentence from Bai Yong's Grammar book]

As the etched lines on computer memory chips have become thinner and the chips' circuits (have become)more complex, the power of both the chips and the electronic devices they drive has vastly increased.  

(this part in the bracket can be omitted)

ETS是越来越滑了，倾向搞这种隐藏式的平行结构来迷惑大家了

请注意上面例句中省略的是相同成分have become而18提中如果省略了could be的话,could be cleaner,be是系动词,第二个第三个变成被动语态标志词be,功能不同,不能省略.而且and后面its crime rate reduced 该句中没有被reduced这个动作的发出者,缺少by某个agent,这种被动语态在gmat中是多次证明错误的.

c正确是因为变成三个句子并列the city’s streets could be cleaner, its fire code could be better enforced, and it could reduce its crime rate

我们要选择的是实质上的并列,而不是形式上的并列,从逻辑意思出发

(18of 41)

According to a recent survey of municipal services, the city’s

streets could be cleaner, its fire code be better
                enforced, and

its crime rate reduced if the current adrninistration improved its

management practices.

 

1)      be better enforced, and its crime rate reduced

2)      better enforced, and its crime rate reduced

3)      could be better enforced, and it could reduce its crime rate

4)      better enforced, and its crime rate could reduce

5)      could be better en forced, and its crime rate reduce

感觉形式对称和意思对称一样重要.

B确实不是很爽.

GWD31是怎么回事阿?

很奇怪的说

如果省略了could be的话,could be cleaner,be是系动词,第二个第三个变成被动语态标志词be,功能不同,不能省略.
