Personal passive

If there are more than one objects in the the active voice sentence (in dative, genitive or prepositional), they undergo no change during the active to passive voice conversion. Here is an example:

active					passive
Die Eltern	schenken	den Kindern	eine Reise.		Eine Reise	wird	den Kindern	geschenkt.

Conversion rule:

Dative, genitive and prepositional objects in the active voice sentence retain their function in the passive voice sentence.
