gwd 13-15

有两个疑问，请大牛看看。

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

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


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


3. Concerns about public health have led between 1876 and 1904 to the construction of three separate sewer systems for serving


4. There were concerns about public health leading to the construction between 1876 and 1904 of three separate sewer systems serving（A）


5. There were concerns leading between 1876 and 1904 to the construction of three separate sewer systems for serving

1、除了between 1876 and 1904要用过去时，a、b比较，b还有哪儿的错误？

1. 没有任何完成时态的标志, B平白多出来完成时态, 不选B.

2. 你体会下意思的区别. 修饰语和被修饰对象分别是什么.

可是construction between 1876 and 1904 of three separate sewer systems 这样的结构OG上不是说不好吗？

construction of three separate sewer systems　between 1876 and 1904我觉得不会产生修饰的错误呀，因为construction是主题词呀？

请指教

i am the same Q ..........

between 1876 to 1904不紧跟它所修饰的construction，产生了介词短语作状语，修饰句子的谓语led to的歧异。鱼子酱mm你觉得呢？

我也有疑问呢。。谢谢

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

我觉得A有点像长定语后置,B的意思像说那些systems置存在于1876 and 1904 间

Noun of Noun这个结构是绝对可以被插入语割裂开的. OG里面说过一个cost of的问题, 但是在大全里面又有一题把cost of分开, 说明这个结构是可以拆开的, GWD还有类似的东西, 大家做的时候可以留心, 这题选A.
