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（D）
(E) using acoustical signals, but not olfactory ones, and attracting
Choice D, the best answer, is concise, maintains parallel structure, and clearly conveys the comparisons being made between the two types of moth. (句子不完整)In A and E, the comparison between most male moths and the male whistling moth is not clear. (？？？)The use of but not does not clearly convey that most other moths use olfactory signals; (？？？)rather than would be preferable, as well as parallel to rather than at night. (这样用法与后面的句子平行)In A, the phrase by the use of is unnecessarily wordy, (繁冗)) and the insertion of they is not required. In E, the final verb should be attract (parallel to call), not attracting (parallel to using)（不平行.）Choice B violates parallelism with by the use of... instead of using, as well as with call... and attractin）Choice C distorts the meaning of the original with its suggestion that male whistling moths call female moths to them both by using acoustical signals and by attracting their mates during the day.

1In A and E, the comparison between most male moths and the male whistling moth is not clear. (？？？
为何比较不清呢
2 The use of but not does not clearly convey that most other moths use olfactory signals; (？？？)
为什么呢
发现OG读了半天 好多不懂 真是急人
谢谢

1- 答案在于2
2 - 没有为什么，OG已经在这句话中将but not和rather than的区别明示了。
not but强调的仅仅是个体的自身，而rather than强调的是比较关系。

这个没明白 能再讲讲吗 谢谢
not ... but仅仅表示自己做了什么，而没做什么，并不强调两者间的比较，换言之，比较对象做什么没有暗示；
而rather than则强调了自己做了A，而没做B，但比较对象却恰恰相反，做了B，而没做A，强调比较关系。
明白了, 谢谢stoneren
我還發現一個小技巧，就是在解比較類型的題目是
rather than 優於but not, 而but not 又再優先於instead of
也就是rather than > but not > instead of

那C的by using对吗？我觉得要不就是by要不就是using. by using意思重复了。望指教！

好像不能這樣講，og的解釋中，有很多都是用...by using.....
例：
21. Defense attorneys have occasionally argued that their clients' misconduct stemmed from a reaction to something ingested, but in attributing criminal or delinquent behavior to some food allergy, the perpetrators are in effect told that they are not responsible for their actions.
(A) in attributing criminal or delinquent behavior to some food allergy
(B) if criminal or delinquent behavior is attributed to an allergy to some food
(C) in attributing behavior that is criminal or delinquent to an allergy to some food
(D) if some food allergy is attributed as the cause of criminal or delinquent behavior
(E) in attributing a food allergy as the cause of criminal or delinquent behavior
In choices A, C, and E, in attributing ... behavior modifies the perpetrators, producing the illogical statement that the perpetrators rather than the defense attorneys are attributing behavior to food allergies. Choice C is also wordy, and attributing ... as is unidiomatic in E. In the correct form of the expression, one attributes x, an effect, to y, a cause; or, if a passive construction is used, x is attributed to y. D avoids the initial modification error by using a passive construction (in which the attributors are not identified), but attributed x as the cause of y is unidiomatic. Choice B is best.
同意楼上观点, by using确实不能当成判断依据, 例外很多.
C里面一个错误是distort the original meaning, 另一个错误就是using的多余.
同意，同意
所以說 by using 和using 的語法都沒有錯
只是純粹比較這兩樣用法 using 比較簡潔是嗎?

good question, Who konws?
I've asked several questions lately but received no reply at all. How about this one?..
“by using...表示一种动作方式, 是不是原文就是省略了by的呢?”
"其实这是一种常见的现在分词短语做方式状语，特别是using...通常前面都不用by。"
The above answer was from LES sometimes ago.

为何比较不清呢
也很困惑？！
分词短语作壮语，一般都用逗号和原文隔开，这里没有逗号，让人觉得怪怪的。
结构上来看，就是call female moths doing sth.; 而其实应该表达的意思是call female moths by doing sth.
请指点，为什么没有by....
