Form of sentence

[Newby]

Hello, I am having trouble with the following sentence:

She used to have long hair.

Would I be correct in saying the FORM of this sentence is made up the following way:

subject + past participal form of the verb 'have' + noun phrase


or is this correct? : used to + verb + noun phrase

or are they both incorrect???

I would be greatful of any assistance.

Thank you - Vicki

Here's how I'd do it:

She (Subject)
used to have (Verb)
long hair (Object of "have")

Note, "used to" takes "have" as its object.

TEST
Verb: Long hair is what she used to have.
Verb: To have long hair is what she used. (ungrammatical)

"used" is not a verb in that sentence. "used to" is the main verb.
