GWD13-15

Q15:

Concerns about public health led to the construction between 1876 and 1904 of three separate sewer systems to serve metropolitan Boston.

why? 我就是根据完成时态来排除的。从句子意思来看，这是发生在过去的事情，没有必要用现在完成时表示迄今为止的含义.

哈哈，同意羅德版主

這題肯定是ABC 選一個，我看法類似，若有既定的年代，過去簡單式即可

A最好

谢谢rhod/agk99

那如何看待

A中的the construction between 1876 and 1904 of three separate sewer systems to serve表达不好

要用the construction of three separate sewer systems

谢谢

B中除了完成时态错误以外（现在完成时可以表示过去发生的事情，和一般过去时互换，但是只是在事情发生的时间不确定的情况下），B中意思变成了three separate sewer systems在1876 和 1904 去服务于手都波士顿，曲解了题目的原意，原文中的 between 1876 and 1904 是修饰the construction的；由此可以引申在改错中经常出现的修饰语位置变换所产生的句意改变的问题，非常多，一定要注意修饰语和被修饰对象，这就是为什么通常要求修饰语紧跟被修饰对象而不能轻易变换位置，当然关键还要看逻辑意思表达的合理性！

leeon 谢谢你啊

我明白了

看来我的语法还是没过关

我再想了想

感觉B的错误在于时态

不在于between..and的结构

因为

BConcerns about public health have led to the construction of three separate sewer systems between 1876 and 1904 to serve

between 1876 and 1904仍是修饰constrction 的

如果要修饰to serve ...

要这样改才对

BConcerns about public health have led to the construction of three separate sewer systems  to serve Boston between 1876 and 1904

B选项：(Concerns about public health) (have led to)( the construction of three separate sewer systems) (between 1876 and 1904 )(to serve）

A选项：(Concerns about public health)( led to )(the construction between 1876 and 1904 of three separate sewer systems )(to serve)

理解为

B选项：(Concerns about public health) (have led to)( the construction of three separate sewer systems between 1876 and 1904 )(to serve）
