因为the last few years 表示的是一个时间段,而且是已经过去的时间段.在过去的几年里,指过去的那段时间当然是过去完成时,如果是特定的过去的一个时间点就用一般过去式.一、过去完成时态 表示发生在过去的动作对过去晚些时候造成的

用现在完成时,因为这指的是始于过去,一直持续到现在的一个时间段 In any event, the economy has developed rapidly in the last few years. 不管怎么说,这几年经济发展是快的.Sales have flattened out in the last few years. 过去几年销售额已逐渐停止增长.Many European banks have merged in the last few years. 在过去的几年里,许多欧洲银行合并了.周末下午答题不容易!对了就 采纳,保准你全家幸福安康!*^__^*
