Q11:

There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

1. There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

2. There are no legal limits on the size of monkfish that can be caught, unlike cod or haddock, a circumstance that contributes to depleting them because they are being overfished.

3. There are legal limits on the size of cod and haddock that can be caught, but not for monkfish, which contributes to its depletion through overfishing.  which 在这里肯定是错的。 
4. Unlike cod and haddock, there are no legal size limits on catching monkfish, which contributes to its depletion by being overfished.

5. Unlike catching cod and haddock, there are no legal size limits on catching monkfish, contributing to their depletion because they are overfished. 答案c 我选e  对称，contributing 的用法也很合适 请问大家的看法

up up 大家快来阿

汗了，感到c和e都错的，e的对比不平行……

召唤nn

我也选a .

个人认为：A,B,E中用了their，不对；D中的being显然不对，那只有选c了。
