分析这句话的时态问题
At least sorting out the things she should【have】 discarded years ago was now being made easier for her
1、其中的have为什么不是had,这里应该表示过去就应该被完成了的.
2、如果说情态动词should后加动词原形,所以had就变成have了,即should have.那这样又怎么能够看出它到底是现在完成时还是过去完成时呢
请从语法上进行分析谢谢

should have done 固定表达,都用于对过去的事情的揣测,跟过去完成时或者现在完成时没多大的关系.
1.表示过去应该做但没有做的事
过去应该已经做的,已经完成的（实际上没做）.
2. 推测过去已经发生的事
再问：如果按这样，那么，这件事他早该5年前就做了和这件事他早该在2010年就做了怎么翻译呢。请翻译下。到时候便采纳你了谢谢
再答： He should have finished it 5 years ago He should have fininshed it in 2010. 其实是一样的！你只要记住这个句型是表示这样的一种意境:描述过去本该发生的事，却没有发生到。
