First, let’s start with an explanation of what passive voice is. Passive voice sentences mention the thing or person receiving an action before mentioning the action itself, and may omit the actor altogether. For example, consider this sentence:
The leaves were blown by the wind.
The leaves receive the action of being blown. In the example, the agent is specified with the preposition by. However, the agent could have been left out of the sentence: The leaves were blown.
