Is it wrong to use negative participle 1 in this way?
She took the keys not even asking whether it was allowed or not.
I believe the correct way is:
She took the keys without even asking whether it was allowed or not.
Actually, I don't really think that backshifting (swapping the tense by one back: is => was) is necessary in this case, and we could've swapped "was" to "is" without significant change in meaning, yet there's always a chance I'm wrong.
Will it be acceptable?
She took the keys not even asking whether it is allowed or not.
I surely appreciate your help.
1
supposed to mean here?1
might refer to the present (-ing) participial form, and would hypothesize that2
might refer to the perfect passive (-ed/-en) participial form. Much like other grammar-school euphemisms, Number 1 and Number. 2.
