标题: 白勇语法全解2－50

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.

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

问题：为什么不能选C？注释写的比较含糊。第一个by using应该没有问题吧，而是第二个by attracting，从语法上讲没错，但从意思上讲就错了，问题就出在这里，注释是这个意思吗？

not by using中的by不能省略吗？就是因为这个原因才错的吗？还是因为attracting？

逻辑意思最大,后面错的严重

by using都可以去掉

而且by attarcting改变了句子得原来意思

attarct 和call平行
