(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

E为啥不对？on comparing和comparisons of 有什么区别？谢谢

在这里不是说on comparing和comparisons of 的区别，根据意思

on 是和base搭配的，在这里介词后面如果有名词形势，就最好不用动名词。

谢谢青鸟!

我明白ON是和BASE的搭配,主要就是不明白什么时候应该用名词形式,什么时候应该用动名词形式,我印象中好些题的答案选择是动名词优先于名词, 所以这里不明白COMPARING与COMPARISONS的选择区别

comparing 强调动作，还有重复进行的意思。

comparison 强调比较的结果。

那么细微的区别，考试时那想得到呀……

anyway, thx allaneli
