Confusing sentence patterns

Dear Teachers,

Hello again. The question that I would like to ask you has something to do with the S+LV+SC and S+V+A patterns.

"I am a girl."  = I understand that this is an S+LV+SC pattern. The same as this:  "We are bored."

But what about this?: "We are here." = Isn't this an S+V+A pattern? I understand that here is an adverb and points out the location of the subject for it answers the question where.

Some of my friends said that it was an S+LV+SC pattern because of the linking verb are, but here isn't a noun nor an adjective. Some also said that it was an S+V pattern.

Can we say that "I am in the office." is an S+LV+SC pattern? Is it possible to use an adverb phrase as the subject complement?

I have searched the net and so far in vain. My grammar books are silent about it too.  Im so confused. Need help.

Thanks a lot,

Specter

S - LV -C

sentence pattern has 4  possible complements...

1. a noun =  She is my teacher

2. an adjective = She is beautiful.

3. a prepositional phrase= She is in the room.

4. Locatives (here, there, everywhere, etc.) = She is here

i hope this one helps....
