Thank you for all your hard work last week,I do not think we--it without you
a,can manage
b,could have managed
c,could manage
d,can have managed
选什么?为什么?

选B could have done 表示过去的虚拟语气的用法
再问：我在网上看到这样一段话，说can have done 表示过去不可能的事现在也没做我觉得和这句话的语境很类似，我认为我们如果没有你就做不了，就是过去其实是有你的，这怎么理解呢？
再答：虚拟用法: could (不能用 can) have done 表示“过去本能够做某事却未做。注意：其否定形式 couldn't have done 没有虚拟语气的用法只能表推测，相当于 can't have done，意为：“过去不可能做了某事例: You could have done it better. 你本可以把这件事做得更好。(事实上做的不是非常完美) If you still feel confused,leave a message please 而楼主网上看到的不是正确的虚拟语气用法呵呵希望对你有所帮助
