If a verb operates with an indirect dative, this dative is retained even in the passive variation.
- They announced these misfortunes to Cato: Cātōnī haec miserea nuntiābant.
- This misfortunes were announced to Cato: Cātonī haec miserea nuntiābantur.
- She offered the queen the swans: rēgīnae cycnōs obtulit.
- The swans were offered to the queen: rēgīnae cycnī oblātī sunt.
- They protected the children from the coming arrows: puerīs aggressās sagittās prohibuērunt.
- The arrows were prevented from reaching the children: puerīs aggressae sagittae prohibitae sunt.
Looking at the Latin, it’s pretty clear that verbs of protecting, defending and prohibiting prefer active constructions, whereas verbs of announcing, giving, presenting etc. are more flexible.
