can have done和could have done的问题,
Thank you for all your hard work last week.I don't think we _______ it without you.
A can have managed B could have managed
有人说这是虚拟语气,那是选B.
更多的人说这是推测语气,A和B都可以表式对last week的推测.为何B对A错?而且后半句的时态不是过去时,又没表示委婉语气,为何用could?

到底是推测还是虚拟语气您看下翻译就知道了
多谢了您上周的努力工作如果没你我不认为我们能将其搞定
说话的时候已经是这些事情全都已经发生了其实这里without you表示的就是假设那么也就是虚拟与去对过去的虚拟就是could have done 的形式
您的支持就是我继续前行及帮助别人的动力愿您与我一起传播『爱心』之种
