Scientists believe that unlike the males of most species of moth, the male whistling moths of

Nambung, Australia, call female moths to them by the use of acoustical signals, but not olfactory

ones, and they attract their mates during the day, rather than at night.

(A) by the use of acoustical signals, but not olfactory ones, and they attract

(B) by the use of acoustical signals instead of using olfactory ones, and attracting

(C) by using acoustical signals, not using olfactory ones, and by attracting

(D) using acoustical signals, rather than olfactory ones, and attract

(E) using acoustical signals, but not olfactory ones, and attracting

句子结构：Scientists believe that…, … male moths… call female moths… using…, rather than…,

and attract their mates...

That引导宾语从句说明believe的内容，从句主语是male whistling moths，并列谓语是call and attract，

现在分词结构using…作伴随方式状语。

A．by the use of笨拙，but not前后连接对象不对等，and they attract没有并列对象

B．by the use of笨拙，instead ofusing…笨拙，and attacting有何using并列的嫌疑

C．not using不平行

D．正确

E．Signals和olfactory ones不对等，and attracting没有平行对象

请问为什么AB选项中的by the use of笨拙呢？？ 我选的是E。。。

个人看法如下：by the use of这样的用法肯定是awkward。可以用一个动词use表达清楚的意思用动词表达是最简洁有效的，即使是被动语态，也常常会优于使用名词。
