问题 Large amounts of water________in the past five years.

选项 A、were polluted
B、was polluted
C、has been polluted
D、have been polluted

答案D

解析 考查现在完成时的被动语态和名词作主语时的主谓一致。句意:在过去的五年里,大量的水被污染了。其一,根据题干的时间状语“in the past five years”可知,此处强调动作从过去到现在的五年中一直持续被污染,因此需要使用现在完成时;其二,large amounts of修饰名词充当主语,谓语动词需要使用复数谓语动词。故选D。
