Does the present progressive have a passive form?
I think it has as it's formed according to the grammatical rules of the English language. It's also in a way necessary especially if it comes to the precision in meaning as well as differenciation between durative and non durative activities.
It's being done.
i don't know
I am being eaten!
i think it has a passive form because the correct form is : present progessive passive . we use is/are being + past participle
i think yes
In my opinion is yes because I think that in every verb tense uses to have or to be
The room is being painted (by the workers).
Sure. The Present Progressive is being used in the passive voice as I type this.
