GWD6-Q27

GWD6-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.

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

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

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

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

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

   Answer: D

问为什么用numbers？wild salmon是一个物种，一个物种的数量用wild salmon's nomber is....不行么？

从另外一个题里节一个句子：Despite the growing number of people who purchase plane tickets online

为什么这里用number?

事实上我认为这题是一个出得很臭的题，number of salmon无疑是更好的表达 但是为了要求by的对称 只能选D

给mm一个建议 不要去钻这样的牛角 就此题来说 salmon's number再不顺眼 你也要选它 当你为number或者numbers纠结的时候 看看别处还有什么更大的错误可以帮你排除错误选项
