   Answer: 

答案 给的是 C， 但我觉得C 不对啊，觉得

 E 才对呢。是答案有问题还是我的功利不够，

请NN们帮一下，快考了。

Unlike catching cod and haddock, there are no legal size limits on catching monkfish, contributing to their depletion because they are overfished.

E项是Unlike A , B v C，这种比较结构要求比较的对象必须是一致的。e.g.Unlike Tom, Jerry likes apples，个人认为 E项对比的对象有问题

呃~~只看了E没看C~

要我的话最后应该会咬牙选下A~~可是A也有问题~~

刚刚搜到了这个问题的争论帖~~http://e.taisha.org/thread-916869-1-30.html

个人认为这种题目还是不要太认真了，

或许出题人的意图就在于考察对比结构，但是最终答案给的也不完美~~
