Hello everybody! I'm an italian student and In these days I will have an exam about phrase analysis -.-
I've got some problems and I hope that someone will help me

-In the sentence:what it's like, it's what a pronoun? I can classify it as a NP? According to me it is a determiner but I don't know how to classify them in phrase analysis.
-[for ever more AdvP], Is an Adverb Phrase?
-affairs of the heart can take rather more time. What is more in this context?
-[twice a year] is it an Adverb Phrase?
-Just as in other major italian cities,.... What is other? It could be a determiner, an adjective and also a pronoun (but not in this case)
Thank you

Veronica
