Passive Voice
2
What is passive voice?
Passive voice is formed by making the object of
the sentence into the subject of the
sentence. e.g. The tiger bites John.
John is bitten by the tiger.
3
When do we use passive voice?

• We use passive voice when
• focusing on the person or thing affected by the
  action. That means the object of the action is
  more important than those who perform the action.
  
• e.g. The tiger bites John.
• (In this sentence, we want to focus on the action
  done by the tiger.)
• e.g. John is bitten by the tiger.
• (In this sentence, we want to focus on John. He
  is the victim.)

4
When do we use passive voice?

• We use passive voice when
• we dont know who did the action.
• e.g. Someone broke the vase.
• (In this sentence, we dont know who broke the
  vase, so we use someone as a subject. However, we
  can use passive voice instead.)
• e.g. The vase was broken.
• (If we dont know who did the action, we can skip
  the subject by using passive voice.)
