【题目】Because society ________ so rapidly during the last few years, the gap between the generations has become larger.
A.changedB.had changed
C.has been changingD.was changed
在线课程【答案】C
【解析】
考查动词时态。句意：因为在过去几年社会变化非常快，不同年代的人之间的代沟也变得更大。主语society和谓语动词change之间是主动关系，根据时间状语“during the last few years”并结合下文“the gap between the generations has become larger”可知，此处描述最近几年一直不断发生的事情对现在造成的影响，并且动作还有可能持续下去，所以用现在完成进行时。故选C项。
