(A) for attracting females rise and fall in accordance with the surrounding temperature, and they can
(B) for attracting females rises and falls in accordance with the surrounding temperature, which can
(C) in attracting females rise and fall in accordance with the surrounding temperature, in fact
(D) to attract females rises and falls in accordance with the surrounding temperature, and it can in
(E) to attract females rises and falls in accordance with the surrounding temperature, in fact
(D)正确,注意到了主谓一致;使用to do表示目的更加有效;用and连接句子,意思符合逻辑
(E)伴随状语使用错误,有作后置定语修饰temperature的歧义存在；possibly使用错误
看过很多帖子讨论这题不选择E因为ving可能做后置定语，修饰前面的名词。但是，如果理解成为，修饰前面整个句子，而不是仅仅某个词时，需要使用ving或者新的概括性名词，这样的用法，那么我认为E答案更完善。因为 the number of chirps per minute本身并不能说serve as a一个温度计，而我认为是the number 随着温度上下浮动这整个动作，才是真正的serve as a thermometer.
不知道这样的理解哪里错了呢？大家一起讨论一下吧。 |
