句子成分的问题

I heard she was pronounced dead on arrival at the hospital.

请问下,dead在这里是主补还是宾补?on arrival理解为时间状语,at the hospital理解为地址状语,如此对吗?

I heard she was pronounced dead on arrival at the hospital.

本句，dead 作主补。主动语态才是宾补：

The hospital pronounced her dead.

on arrival at the hospital：总体看作时间状语，不要细分。由于 arrival 后面没 at the hospital，就不完整。
