OG_10_212, 过去分词引导状语从句

The Baldrick Manufacturing Company has for

several years followed a policy aimed at decreasing operating costs and improving the efficiency of its distribution system.

(A)  aimed at decreasing operating costs and improving

(B)  aimed at the decreasing of operating costs and to improve

(C)  aiming at the decreasing of operating costs and improving

(D)  the aim of which is the decreasing of operating
                costs and improving

(E)  with the aim to decrease operating costs and to
                improve

为什么选aimed引导状语从句，可以吗？

请教LZ，这里为什么说是壮语从句啊？

我这题的思路就是平行啊，B,C,D不平行首先排除，E选项with the aim... improve can easily be construed as referring to the Baldrick Manufac­turing Company and so does not refer unequivocally to policy. 容易产生”那个公司带着…的目的”的修饰歧义。所以选A

(A)  aimed at decreasing operating costs and improving

(B)  aimed at the decreasing of operating costs and to improve

(C)  aiming at the decreasing of operating costs and improving

(D)  the aim of which is the decreasing of operating costs and improving

(E)   with the aim to decrease operating costs and to improve

aimed at紧接着名词policy，修饰policy

to elinaqu：

aimed at decreasing and improving, 好像是decrease/improve平行.

to dingxiang,

是否可以用aiming 来修饰前面has followed for many years a policy?

感觉这样意思更清晰。

就是decreasing 和improving平行
