1. Active and Passive Voice
English 2

2. Active Voice
If you are active, you are doing something. In a sentence written in active voice, the subject of the sentence is doing the verb.
Mrs. Olsen ate the Twix bar.
The students wrote the paper.
Arwen cleaned Zarina.

3. Passive Voice
If you are passive, something is being done to you. In a sentence written in passive voice, the subject of the sentence is having the action of the verb done to it by something else.
The Twix bar was eaten by Mrs. Olsen
The paper was written by the students.
Zarina was cleaned by Arwen.

4. Why does this matter?
When you write sentences with active voice, you can use more interesting verbs and your writing seems to move more quickly (and you look more mature as a writer!)
The cats raced around the house, jumping on chairs, performing acrobatic maneuvers as they ran towards the food dish.
In the sentence above, the focus is on the action of the cats.
The house was raced around by the cats, chairs were jumped on, acrobatic maneuvers were performed as the food dish was run towards.
In the sentence above, the focus is on the objects, not the actions.
