In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer. (D) to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve (E)to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving 答案选E,说serving有修饰temperature的嫌疑 但是D中的it不是更加指代不清吗??它可以指代temperature也可以指代number什么的啊~~ 疑惑~~ -- by 会员 bobo1990 (2010/9/10 10:53:32)
it代名词优先指代主要子句主词the number of chirps,没有指代不清的嫌疑。 E我认为最错的地方是possibly无法取代can的句意,原题的can依造句意指的是可以、能(be able to)的意思,而非可能(possible)的意思。 |
