Q27: PP76.

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

答案是D。我选的是A。
有两个问题：
1）Ving不加逗号是名词修饰语，修饰就近名词。但是照这里的用法，应该是伴随的用法，但是缺逗号啊。SO，为什么不用by？
2）D选项逗号后面是不是少一个主语啊？就是“，and attract”这里，逗号后面应该要有个主语吧，因为这个我才更加确定选了A。

大家帮我看一看吧~
