Iawfy

我怎么觉着A也读的通呀!

A和E有什么不同呢????

Iawfy

哦~如果把A中的have been 改成has been就对了,是吧!

这个是过去完成时的被动语态, 所以B不对

同問,,我也覺得怪怪的..但看來看去只有E怪的少

这题真的很难选，无奈中我选了E，主要是考虑到未画线部分的by对称。

而这里的numbers一直让我难以理解，是不是除了“数量”外还有其他的意思？如果不是这个numbers这个选项就很完美。

B中间的 deep-sea and coastal netting is not controlled，is不对吧，要用are。就算are，也和后面的不对称。

I picked E because all others have some obvious faults.

A. have been reduced --> has been reduced.  The first part of the sentence is not parallel with the 2nd.

B. is not controlled --> are not controlled.  The first part of the sentence is not parallel with the 2nd.

C. has been reduced --> have been reduced.  The first part of the sentence is not parallel with the 2nd.

D. is not controlled --> are not controlled.  Awkward.

however, can we use "wild salmon’s numbers" ?
