Can can be used in Negative when one doesn't believe something happened or turns down the possibility it happened. But:
1- Can he have said it?
2- How can he have done that?
3- Can she be washing up the dishes?
My question is that can we use 'can be Ving and can have V3' in positive and negative questions? Are they OK?
Re: can be
Yes you can. How would you negate your three sentences?
