帮我分析一下英语句子A persone ought not to forget to use tact and cour

主语a person,谓语是情态动词ought not to forget,"to use..."动词不定式充当“大宾语“,在大宾语中tack and courtesy 充当use的宾语,in dealing with others 介词短语充当限制成分,用法是use sth.in sth.
句子可以这样划分
A person (ought not to forget) to use( tact and courtesy )in (dealing with others.）
