1. ACTIVE VS. PASSIVE VOICE
“Verbs are the most important of all your tools. They push the sentence forward and give it momentum. Active verbs push hard; passive verbs tug fitfully.”
-- William Zinsser,
On Writing Well

2. Active Voice
In a sentence using active voice, the subject of the sentence performs the action expressed in the verb.
Ex. The dog bit the boy.

3. What is Active Voice?
In the Active voice, the subject performs the action.
For example:
Joseph draws a picture.
Joseph is the subject and he is doing something (drawing).

4. Passive voice Use of the Passive Voice We use the passive when:
we want to make the active object more important or we do not know the active subject
Example: President Kennedy was killed by Lee Harvey Oswald.
My wallet was stolen
to be verbs include am, is, are, was, were, been, being, be, have, has, had

5. Passive Voice (con’d)
Also use passive voice when you wish to emphasize what happened and the person or thing acting is unknown or unimportant.
Example
Poisonous gases were found in six factories.
The use of passive emphasizes the finding of
gases, not who found them.
Note: Because passive voice often leads to awkward or wordy
constructions, use passive voice sparingly and with good reason.

6. When to use passive voice
Use passive voice when you do not wish to emphasize the subject of the sentence.
Example:
Smoking is prohibited. (passive)
The management prohibits smoking. (active)
The passive sentence takes attention away from management, so they do not have to be in the role of the “bad guys.”

7. Active vs. Passive
Active: The dispatcher is notifying police that three prisoners have escaped.
Passive: Police are being notified that three prisoners have escaped.
