og11th t5 虚拟语气现在和过去表达法 求助

The company has become increasingly willingto compete for the mass market sales they would in the past have conceded to rivals.

第五题划线部分they would in the past have conceded to the rivals 中

我始终弄不清为什么要用would have done的句型而不是would do

在前文中表明的是现在完成的状态，同现在状态相反的虚拟语气应该是would do吧？

而且用到的时间也是in the past……

小女子初来乍到，希望大家谈谈自己的看法

正因为是in the past 说明是与过去事实相反 所以用would have虚拟啊

恩~谢谢楼上的分享~

还是有道理的，慢慢体会下~
