Question

i couldn't have done it without you

判断一下这里的can是表示虚拟语气还是推测
I can't do that without you.
I don't think I could have done it without you.
我觉得第二个是虚拟语气,第一个表示否定推测也可以,不一定是虚拟语气吧?

Answer 1

I can't do that without you
表示不能.意思是 没有你,我做不了那件事.
表示的是能不能.不是虚拟语气
I don't think I could have done it without you.
否定前置,转换下市：Ithink I cound not have dont it without you.
我想,没有你,我做不成那件事.
虚拟语气用来表示说话人的主观愿望或假想,而不表示客观存在的事实,所说的是一个条件,不一定是事实,或与事实相反.
第二个是虚拟句,是一种假想,不是客观存在的事实
