[問題]OG264

264. 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


因為認為要加by，所以沒有選(D)(E)，另外雖然知道(A)(B)by the use of 比by using囉嗦，但是(C)attract不對稱，故給它選了(A)
可是這一題答案卻是不用加by,形成using acoutstical singals修飾them(the male whistling moths)，語意似乎因此而不同
請問個為大牛們的看法?謝謝

by / use 都是表方法 一起使用表redundancy
既然都是表方法 就沒有改變句意的意思

光這點 就把abc刪掉的

A還而且 有其他錯點
and連接兩個動作
如果主詞相同 則不可用,and連接兩個獨立句子
也算是redundancy
還有but not 不可連用
這些OG詳解裡都有提到 蠻清楚的
你可以再看一次唷
