Q27:

In Scotland, the number of wild salmon have been reduced because of uncontrolled deep-sea and costal 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

Answer:  e

想知道下，D错在哪里？not controlled 跟 uncontrolled 有区别吗？

n. + that is adj. 错。应该是用adj. +n ，因为更简洁。另外D的并列有错误。

deep-sea and coastal netting that is ||不是应该that are 吗

我认为D有3出错误：

1. 原文时态是完成时态，选项尽量不要改变时态

2.正如楼上所说， that be 构成不简洁错误

3.不平行对称，by....by ....by..

E 正确 --既没有改变原文的完成时态而且又构成了

reduced by uncontrolled deep-sea and coastal netting, by pollution ,and by various other ....
