@cicerone imposter,
I understand the basics. I don't know why the rest of my post got cut off.
Quite frankly Ive asked a few people and they all tell me different answers
My first thoughts were
For the first sentence
"work" is the subject "is" is the verb and "all they ever talk about" is an adverbial phrase
for the second sentence
"hanging out with her co-workers" is the subject "is" is the verb "all she ever does" is the adverbial phrase
Then I was told
"they" is the subject "talk" is the verb "work" is the object "all" and "ever" are adverbs describing "talk"
For the second sentence "She" is the subject "Does" is the verb "Hang out" is the object
Then someone told me
In the first sentence "all" is the subject, "is" is the verb, "work" is the predicate. "[that] they ever talk about" is a relative clause modifying "all". The second sentence has a similar structure, and "hang out with her coworkers" is the predicate. There are no direct objects in the primary structures of these sentences.
So I'm not sure
