Help with structure

Hi
I think if you want to analyize it

'He swallowed a lot of new questions which had just occured to him, and looked instead at the thousands of narrow boxes piled neatly right to the ceiling."

i think it will be (clauses )
- he swallowed a lot of new questions
- hwich had just occured to him
- and looked instead
- at the thousands of narrow boxes piled neatly right to the celing .

I'm not sure . I hope it will be true

He swallowed a lot of new questions which had just occured to him, and looked instead at the thousands of narrow boxes piled neatly right to the ceiling.

He | swallowed ... and looked (instead)
subject | verbs joined by a conjunction (adverb)

swallowed | a lot of new questions
verb | complement of the verb, i.e., direct object - also antecedent to "which"

questions: which (the questions) | had occurred | to him
relative pronoun | verb phrase | prepositional phrase - indirect object pronoun "him"
relative clause functioning as an adjective to "questions"

looked | at the thousands of narrow boxes OR looked at | the thousands of narrow boxes
verb | prepositional phrases OR verb | complement, i.e., direct object

boxes | [which were] piled neatly right to the ceiling
direct object | modifying past participle phrase equivalent to a relative clause with "which were" deleted

piled | neatly | right | to the ceiling

past (passive) participle | adverb of manner | adverb of degree modifying the following | prepositional phrase

Well, it's a start, anyway!

I would analyse it this way:

- "He swallowed a lot of new questions" - main clause; he = subject, swallowed = predicate, a lot of new questions = direct object

- "which had just occured to him" - subordinate clause, functioning as an object complement; internal analysis: which = relative pronoun, had occured = predicate, to him = direct object

- "and looked instead at the thousands of narrow boxes" - subordinate clause, functioning as an adverbial; internal analysis: and = conjunction; looked at = predicate; the thousands of narrow boxes = direct object

- "(which were) piled neatly right to the ceiling" - subordinate clause, functioning as an object complement; internal analysis: piled = predicate, neatly = adverbial, to the ceiling = adverbial.


That´s the way I learned it and I hope it´s correct...
