"I am a nurse at the hospital"

"I have a test tomorrow"

"I am a soldier at heart"

Whenever, there are nouns after a "to be" or "to have" verb, and then there are adverbs after the nouns, do the adverbs modify the state of having or being, or the noun? Are there any exceptiont that I should I know?

And how about this sentence:

"I am going to a concert tomorrow"

The verb is present tense.. so what does tomorrow modify? And why?

Oh and also,

"I gave book to you"

"you" is the indirect obj. But what does "to you" modify? The verb give or the book?

The adverb modifies the verb.  "Am going" may be present tense, but it refers to a future action.  It's contextual.  However, "I am going through menopause" refers to a present action.

Are we talking about wagering here?    Ah, the book!

I gave you the book.  I'm sure you realize "you" is the indirect object of the verb.  I presume it may be said to modify the verb, although I've never thought about it.

I confess wondering if "to you" is also considered a prepositional phrase.

But there's no question in my mind that "to you" describes the action "to give," and not the direct object "book."  It answers the question, "Give how?"  Not the question, "Give what?"
