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.
(A) for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve
(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.
这个题选D不选E的原因是因为原句中有使用正确的情态动词就不能改成分词吗？还是因为逻辑主语不对？
