og264 problem of choice a,e

Across

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

Choice D, the best answer, is concise, maintains parallel structure, and clearly conveys the comparisons being made between the two types of moth. 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. In A, the phrase by the use of is unnecessarily wordy, and the insertion of they is not required. In E, the final verb should be attract (parallel to call), not attracting (parallel to using). Choice B violates parallelism with by the use of... instead of using, as well as with call... and attracting. 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. The insertion of using in not using olfactory ones is unnecessary.

fficeffice" />这个加亮的地方倒底是什么意思呐?

是不是说有嫌疑是把olfactory ones读成和female moths并列呐?是不是因为有这原因ets才有加了个and attracting来加强e的错误呐?

另外,为啥call 一定要和attract 并列呐?                 是不是在a里头的 call famale moths...., using...., and attract their female mates...(using后头的宾语完全不能和call, attract后的并列呐????)...就是a里头的逻辑关系必须保持着...

中文乱七八糟,不知道说清楚了么

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---

-->> not very clear what that means, but 'rathen than is always
preferred in a comparison. and 'but not' doesn't make it clear which is
parallel to which



另
外,为啥call 一定要和attract 并列呐?                 是不是在a里头的 call famale moths....,
using...., and attract their female mates...(using后头的宾语完全不能和call,
attract后的并列呐????)...就是a里头的逻辑关系必须保持着.

-----> it's got to be logical:

male moths in Aus. use acoustical signals, rather than olfactory ones,
to call and attract females. Now it should be clear for parallelism

以下是引用Snazzy在2004-3-5 6:20:00的发言：
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---
-->> not very clear what that means, but 'rathen than is always preferred in a comparison. and 'but not' doesn't make it clear which is parallel to which (可是还是不知道but not是什么意思)

    


是不是说有嫌疑是把olfactory ones读成和female moths并列呐? 这个还是没得到回答......

另外,为啥call 一定要和attract 并列呐?                 是不是在a里头的 call famale moths...., using...., and attract their female mates...(using后头的宾语完全不能和call, attract后的并列呐????)...就是a里头的逻辑关系必须保持着.
-----> it's got to be logical:
male moths in Aus. use acoustical signals, rather than olfactory ones, to call and attract females. Now it should be clear for parallelism (这个我晓得啦,谢谢snazzy,可是这个好像还是不对: 好像应该是强调用acoustical signals 来呼唤,在白天而不是黑夜来吸引(不是强调用acoustical signals 来吸引.))

请指教呵~~快不好意思问了

OG是讲说unlike the males of most species of moth, the male whistling moths of Nambung, Australia, .......... but not olfactory ones

一般but当连词(即逗号+but), 在一般情况下, 通常当主语but后面的N当主语, 造成如OG所说的比较关系不对等....

恩，我想but后的句子： not olfactory ones和call female moths to them 是平行的 ，所以does not clearly convey that most other moths use olfactory signals

魚子醬秋天

大家说的都没错

我在把她搞简单点

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.

单看这个句子  

A but not B

并列比较的对象 为 female moths 杠上 olfactory ones

还原句意 为

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

或是 好看一点的句子为

call female moths but not olfactory ones, to them by the use of acoustical signals～～

这样的句意　　非常的吊诡　吧　单然是错误选项噜

解决了这一层之后　不知版主对于　and attract 的部分是否还有疑惑 ??

若有  咱们再来讨论呗

今天mouse 非常不听话 气气气!!!

高啊vincent，你又点醒我了。是说a/e中but后的ones有可能指代到前句的 the male whistling moths of Nambung造成比较对象的歧义，对吧，谢谢！

en....

In A and E the comparison between most male moths and the male whistling moth is not clear Because The use of but not (in A and E) does not clearly convey that most other moths use olfactory signals.
