- We use the passive voice when the action is more important than the subject who did it.
- When the author is obvious or unknown.
- When the complement is more important than the subject.
NOTES:
- If we want to say the author we add BY at the end of the sentence followed by who did it.
- There are direct passives where the direct object becomes the subject: A box was sent to me by John.
- There are indirect passives where the indirect object becomes the subject: I was sent a box by John.
