Hi
My degree is in English Language. These sentences are not the type that would normally be passivised in English; although maybe you could passivise a) as "Milk is contained (in the bottle)." Sentence b) could technically be passivised as "To help you is wished (by me)," but this doesn't feel correct. Through it-clefting you could adapt it to "It is wished (by me) to help you," but, again, this wouldn't be used in reality.
I think the problem in passivising sentence a) is that the agent (the bottle) isn't active, which would normally be the case in something that could be passivised. In sentence b) the verb (wish) isn't transitive. Usually, only transitive verbs are passivised.
Hope this helps.
Shaun
