1. Passive voice vs active voice
The passive voice focuses on who or what is affected by an action, not on who does the action.
The active voice highlights who or what performs the action.
Passive voice: π Robert painted the wall yesterday (= we are interested in Robert who performed the action of painting, not the wall).
Active voice: π The wall was painted by Robert yesterday (= the focus is on the wall, not on Robert).

3. When should you use the passive voice?
There are situations when the passive voice is the better option. Here are some situations:
When you want to highlight the object
π The dog was chased by the cat
makes the dog, and what happened to it, the main focus. An active version, π The cat chased the dog
, puts more emphasis on the cat.
When you don’t know or it’s not important who carried out the action.
π The TV was broken
, if it’s not important (or known) who broke the TV, this passive sentence is appropriate. But, if it’s relevant who broke it, an active sentence like π John broke the TV
would be better.
When your audience doesn’t need to know who did the action.
This can sometimes be tricky to decide. Imagine the two sentences:
- (passive) π
A new park was opened in the city yesterday
, - (active) π
The mayor opened a new park in the city yesterday
.
The first sentence might be more suitable for a local news report where the main interest is the new park. The second might be more suitable for a political news piece where the mayor’s actions are under scrutiny.
