I wanted to clarify the question of prepositional phrasal verbs for myself. I have faced a tricky sentence, and I would like to discover if I can change the location of the preposition 'at'. If not, I would like to understand why. Here is the sentence:
He is handsome enough to be looked at by any passenger.
Can the sentence be changed to:
He is handsome enough to be looked by any passenger at.
The verb 'look at' is a prepositional phrasal verb. It is intransitive in the active voice: 'I look at you'. Can we turn this into the passive voice as: 'You are looked by me at'? Does the preposition 'at' turn into an adverb in that case?
