In Scotland, the number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting, by pollution, and by various other threats to the fish’s habitat.

A. number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting,

B. number of wild salmon is reduced because deep-sea and coastal netting is not controlled,

C. numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting,

D. wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled,

E. wild salmon’s numbers have been reduced by uncontrolled deep-sea and coastal netting,

排除ABC，还有D和E，正确答案是E

看E选项

不理解：coastal netting是一个动作，所以uncontrolled is OK，但是deep-sea能被control或是uncontrol吗？～还是说deep-sea是一个与netting相仿的术語？

非常感谢 ！

啊。谢谢！我晕倒了。

哭啊。我脑袋短路了

我还有一个问题

E. wild salmon’s numbers
                    have been reduced by uncontrolled deep-sea and coastal netting,

既然是表示数量， 能用复数numbers表示吗？？

我记得OG中有一题就是根据number的逻辑意思 从而排除numbers的呀。。困惑。。。。

这些都不用管吧..后面的by平行就只有E符合了..
