- Let this house.
- Over the field, the grass grows
For the first sentence, I changed the voice from active to passive voice. For the second sentence, I changed the voice from active to passive voice too.
Active Voice is when the subject is doing the action. For example, here's another sentence using active voice:
"Luna danced on the forest's ground."
The subject of the sentence (Luna) is doing the action (dancing in the forest).
Passive Voice is when the subject is acted on by the verb. For example, here's the same sentence using passive voice:
"The forest's ground was danced on by Luna."
Luna is acting upon the sentence subject (the forest's ground).
Hope that helped!
