还有问题！！！！！快来帮我解决它！！
Although the lesser cornstalk borer is widely distributed, control of them is necessary only in the South
A.the lesser cornstalk borer is widely distributed,control of them is
B. widely distributed,measures to control the lesser cornstalk borer are
C. widely distributed, lesser cornstalk borer control is
D. the lesser cornstalk borer is widely distributed, measures to control it are
E. it is widely distributed, control of the lesser cornstalk borer is

答案选D，我想问although前后两句主语不是要一样的吗？D选项，前句主语the lesser cornstalk borer，而后句主语却不是这个
以往做题，我会扫一下选项，it一般出现在句后都有指代不清的现象，是有这样的规律吗？
请问C选项哪里有问题？

although前后两句主语不一定要一样。 D中的it只能指代前句中的borer

C选项前句省略了主语，那么意味着前句主语=后句主句，但widely distributed 主语并不是measures 所以不对。
