Personal passive

Adverbial complements of all kinds that are contained in the active voice sentence retain their function in the passive voice sentence and undergo no change. Here is an example:

active
Das Elektrogeschäft	informiert	Interessenten	regelmäßig	über neue Produkte.

passive
Interessenten	werden	regelmäßig	über neue Produkte.	informiert.

Conversion rule:

Adverbial complements in the active voice sentence retain their function in the passive voice sentence.
