885 Section 3-7 答案有误？

7.     Many investors base their choice between bonds and stocks on comparing bond yields to the dividends available on common stocks.

(A) between bonds and stocks on comparing bond yields to

(B) among bonds and stocks on comparisons of bond yields to

(C) between bonds and stocks on comparisons of bond yields with

(D) among bonds and stocks on comparing bond yields and（C）

(E) between bonds and stocks on comparing bond yields with

答案应该为E。

理由有二：

1. comparison of 的用法有问题：

例：a comparison of pollution levels in Chicago and Detroit  朗文英英词典

从上例来看，正确的用法是a comparison of sth，从未见过a comparison of A with B的

2. comparison是uncountable noun 朗文英英词典

comparisons应该是必错的

还是C 不是E 首先根据campare to 是比喻的意思排除 A B

其次 因为是两种事物的比较 所以不能用AMONG 排除D

在剩下的 C E中 ON 后应该跟 宾语 因为 compare 有其名次形式 comparison C更优于 E

comparison不可数，comparisons不是必错吗？
