Are all of these words in caps predicate nominatives?

1.Isn't this movie THE BLACK STALLION?

2.Have you met DR.CARLOS WHITMAN, Sally?

3.The winner of the first place ribbon for science is ROBIN SENAROS!

4.Email DAD a copy of the photograph tonight.

Thanks!

No.

Two are; two aren't. Do you need good websites to determine which ones?

I've checked out the sites but I'm still confused...

I don't think #4 is one
I have no clue actually. This is hard

To have a predicate nominative, you must have a linking verb (not a form of "to be" that is a helping verb!).

My brother is a tall lumberjack.
"lumberjack" = pred nom because it's a NOUN that is referring to the same person as "brother." Here's another way to visualize what happens in a sentence with a pred. nom. --

subject = pred.nom.

A direct object, on the other hand, receives the action of an active voice action verb: John hit the baseball.
"baseball" is the direct object.

So ... which ones have predicate nominatives?

#1 is tricky because whoever wrote these sentences put it in the form of a question, reversing the verb and subject. Try it in normal word order:

This movie is not THE BLACK STALLION?

So #1 isn't a predicate nominative

If none of that makes sense, then start from scratch.

What are the main verbs in each of those 4 sentences?

Main verbs?

#2 = met

#4 = email
?

OK, those two are ACTION verbs, not linking verbs. They will never have pred noms after them.

So ... tell me what you think of 1 and 3? What are those sentences' verbs?
