Question

Thank you for your help.
I'd like to post questions related to prepositional phrases which sometimes ambiguous.

1. He has made coffee for all of us.
2. Please boil enough rice for ten people.
3. Won't you play a Beethoven sonata for me?
4. We must choose suitable presents for your nephews and nieces.
5. I've bought some chocolate for you.
6. Our school held a fund-raising event for poor children.

[Among the six sentences, which prepositional phrases are adjective phrases and adverb phrases? I mean the pattern 'for ...'. Don't they have the same pattern? ]

7. Our school held poor children a fund-raising event.
[Is #7 a correct sentence?]

#7 would never be used. It's too awkward.

The other sentences are fine. In these sentences, I take the "for..." prepositional phrases as adjective phrases:
1, 2, 4, 6.

Answer 1

1 - adverb phrase. "for all of us" tells how much to make. It modifies, defines the verb
2 - adverb phrase. "for ten people" modifies the adverb "enough", which modifies the verb "boil".
3 - adverb phrase. "for me" modifies the verb "play".
4 - adjective phrase. "for..." modifies the noun "presents".
5 - adverb phrase. "for you" modifies the verb "bought".
6 - adjective phrase. "for poor children" modifies the noun "event".
