Every possible means _____ to prevent the air pollution, but the sky is still not clear.
A.is usedB.are usedC.has been usedD.have been used

答案
C
解析

试题分析: 考察主谓一致。本题主语中的名词means是一个单复数同形的名词,要在具体语境中判断是单数还是复数。本句中的形容词every后面通常要节单数名词,故使用AC,根据句义说明这是已经发生的事情,故使用现在完成时。句义:每一种可能的方法都已经被使用来预防空气污染,但是天空仍然不晴朗。故C正确。
