I have the following examples from a corpus (ICNALE corpus)
"They can grow as a member of society."
"At university, students are regarded as adults not children."
"I worked in a hotel as a service staff."
According to Longman Grammar of Spoken and Written English (Biber, Johannson, Leech, Conrad, Finegan, 1999, p.776-783), circumstance adverbials can be classified semantically into Place, Time, Process (manner, comparison, accompaniment, means, instrument), Contingency (cause, reason, purpose, concession, condition, result), Extent, Addition/Restriction.
I am having trouble classifying the adverbials in the above three sentences: as a member of society, as adults, as a service staff member.
EDIT: As BillJ points out below, the adverbials in the three sentences are complements (not adjuncts / circumstance), but I am still looking to see if they can be assigned a semantic category.
Any help appreciated! Thanks!
