GWD31-18的省略？

18. GWD31-Q18

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 kit 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

答案是C,讨论贴一半B一半C，我以前选B,现在觉得是C.不知道可以这样省略吗，请NN指点。

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

streets could be cleaner, its fire code (COULD be) better enforced, and

its crime rate (COULD BE) reduced if the current adrninistration improved its

management practices

还是B， 我觉得C不平行.

引用titatita的解释:

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

我支持C

对不起LZ，我觉得是我错了!!

但那个it指代什么呢？

应该是指代the current administration improved its management practice整句话吧，这种指代在GMAT中也是

绝对错误的！

也没搞懂，但是如果考虑“逗号”不能连接两个句子，c好像就不对了。
