More about passive and active voices:
We can also distinguish personal from impersonal passive.
Firstly, Personal passive = the object of the active sentences becomes the subject of the passive sentence. So all transitive verbs can form a personal passive, (a transitive verb means that it can be followed by an Object).
Example: She built a new house. A new house was built.
Secondly, Impersonal passive = verbs that cannot have an object are intransitive verbs. They cannot form a personal passive sentence (meaning there is no object in the active voice that can be used as the subject of the passive form/sentence). In this case and in order to use the same verb in both the active and passive voice, you will need the preposition “it” (impersonal construction).
They said becomes, It is said.
