Question

A lot of fish in the river _______ recently, because there is lots of pollution.

A. has died       B. has been dead

C. have been dead  D. have died

Answer

D

【解析】

试题分析：句意：最近河里的很多鱼都死了，因为污染太严重了。has died 死了；has been died现在完成时的被动语态；have been dead死了；have died死了。根据句意和句中的recently可知，这句话应该用现在完成时态，这句话的主语a lot of fish是复数形式，故应选D。

考点：考查动词时态。
