Answer:
Passive voice.
Step-by-step explanation:
Active voice tells us what a person or thing does. The subject performs the action (verb) on the object.
{Subject + verb + object}.
Active voice: A horse called Northern Dancer won the Queen's plate.
This sentence tells us what horse does (wins).
Passive voice tells us what is done to someone or something.
{Object + verb + subject}.
Passive voice: The Queen's plate was won by a horse called Northern Dancer.
This sentence tells us what is done (won) to a horse called Northern Dancer.
Hope this helps :)
