Question

【题目】More than 70,000,000 sharks _________for their fins(鱼翅) last year.

A.were killedB.have killedC.will killD.are killed

Answer 1

【答案】A

【解析】

句意：超过70000000条鲨鱼因为鱼翅被杀去年。

考查被动语态。were killed一般过去时被动语态；have killed现在完成时；will kill一般将来时；are killed一般现在时被动语态；根据“last year”所以用一般过去时。“sharks”跟“kill”是被动关系，故选A。
