The underlined portions appear to be: a difficult assignment, rarely, happily, tomorrow, beautiful, carefully, a doctor, already, late, never, and on the table. The text after “Mark (12)” is cut off, so that part cannot be answered; please provide the complete sentence.
- a difficult assignment — direct object: it answers “What did our teacher give us?”
- rarely — adverb of frequency; it modifies “visits.”
- happily — adverb of manner; it modifies “played.”
- tomorrow — adverbial of time; it tells when we will meet them.
- beautiful — adjective; it modifies “flowers.”
- carefully — adverb of manner; it modifies “answered.”
- a doctor — subject complement (predicative noun) after the linking verb “is.”
- already — adverb; it modifies “have finished.”
- late — adverb of time; it modifies “arrived.”
- never — adverb of frequency; it modifies “have seen.”
- on the table — prepositional phrase functioning as a postmodifier of “book.”
