1. They parted good friends.
“good friends” = Subject complement or Adverbial (optional or obligatory) ?
Optional- you don't need to tell me how they parted.
2. They married young.
“Young” = Subj. compl. or Adverbial (opt. or oblig.) ?
Optional- I'd say this was a complement as it descibes them more than the marriage, but you could argue that it describes the way the got married.
3. The sun shone bright.
= bright = Adverbial of manner ? (opt. or oblig.?)
4. Hungrily, the dog smelled at the package.
- Verb = “smell” or “smell at”?
- Direct object = “at the package”; OR
- “the package = object of the preposition “at”?
- Hungrily = optional or obligatory adverbial of manner?
Hmm, 'hungrily' is optional, but if you remove 'at the package', you imply something else- namely, that the dog smelled bad to other people, in which case you'd have to remove 'hungrily' as well, but you woukld have a very different meaning- from hungry dog to stinky dog.
5. She has quite rapidly become an expert.
"an expert" = Subj. complement
"quite rapidly" = Adv. of time (opt. or oblig.) ?
6. The phone rang loudly in the night. =
optional or obligatory adverbials?
7. She is remaining at Cambridge.
"is remaining" = intransitive verb ?
"at Cambridge" = optional or oblig. adverbial of place?
8. My watch has disappeared from my desk.
"has disappeared" = intransitive verb ?
"from my desk" = opt. or oblig. adverbial of place ?
9. The soldiers fought well. = S V A(manner) ?
optional or obligatory?
However, I can't really see what you're doing here- you can take a lot out, but you end up with something different- you can say 'the phone rang', but that's quite a way from where you started.
