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 administration improved its management practices.

A. be better enforced, and its crime rate reduced  
B. better enforced, and its crime rate reduced  
C. could be better enforced, and it could reduce its crime rate
D. better enforced, and its crime rate could reduce  
E. could be better enforced, and its crime rate reduce


ANS:B


解释上面说是B选项中省略了could be，然后还是并列……
我不太理解这里为什么可以省略……是有这样的固定用法吗？
谢谢大家的帮助~~~

C的it指代啥啊？这个有歧义啊。

能省略也可以不省略，不省略不一定错。只是罗嗦一点，没有正确选项的时候，可以选择罗嗦一点的选项。
这里的问题主要是后面两个分组都是被动语态，could be要省就一起省，要留就一起留。而逻辑意思是这三者都是if之后的结果，所以DE有单独把if的假设给到了crime rate去了。

我是觉得it指代city，因为前面就是这样用的啊~

It指代City就不对啊，句子的逻辑是services使得城市的各个指标更好了，而不是城市本身。

即使这个点不好理解。C还有一个错误就是，如果and it could reduce...这里用and把句子分成了两个并列部分。那么the city’s streets could be cleaner, its fire code be better enforced这两个就是一个并列关系，应该在its fire之前加个and，并去掉逗号。因为两个并列关系的语句必须用连词连接。
