Meet the Contenders
Voice tells us who the main character of the sentence is. Let's see how our two contenders handle the action!
🦸♂️ Active Voice: The Action Hero
The subject is the hero who **PERFORMS** the action. It's direct, strong, and clear!
Formula:
Subject (Hero) + Verb (Action) + Object (Receives Action)
Example:
Maria kicked the ball.
🕵️♀️ Passive Voice: The Mystery Solver
The subject **RECEIVES** the action. The focus is on what happened, not who did it.
Formula:
Object + 'to be' verb + Verb (Action) + by + Subject (Hero)
Example:
The ball was kicked by Maria.
Meet the Players
Before the showdown, let's practice finding the key parts of a sentence. First select a part, then click the word(s) in the sentence below.
The Secret Weapon!
Here's a secret trick to find the passive voice. Add "by zombies" after the action. If it makes sense, it's passive!
🧟
"The window was broken..." → "The window was broken by zombies." (Makes sense! It's passive!)
"The boy broke the window..." → "The boy broke the window by zombies." (Sounds silly! It's active!)

Sentence Surgery: Active to Passive
Let's operate on a sentence! Follow these 4 steps.
Original Sentence: The cat chased the mouse.
Step 1 & 2: Swap the subject and the object.
the mouse chased The cat
Step 3: Add a 'to be' verb (like was) and change the verb to its past participle.
the mouse was chased The cat
Step 4: Add the word 'by'.
Final Sentence: The mouse was chased by the cat.
Reversing the Mystery: Passive to Active
Let's flip it back! It's just as easy.
Original Sentence: The homework was finished by the student.
Step 1: Find the real hero after the word 'by'.
It's the student!
Step 2 & 3: Move the hero to the front and fix the verb (remove 'was').
The student finished ...
Step 4: Move the object to the end.
Final Sentence: The student finished the homework.
The Training Ground
Time to test your skills! Identify the voice, then transform the sentence.
Sentence 1 of 4:
Is this sentence Active or Passive?
Great! Now
When Should I Use Passive Voice?
Active voice is usually your best choice, but passive voice is very useful sometimes. Here's when:
❓
When you don't know who did it
"My bike was stolen."
🤷
When it's not important who did it
"The bridge was built last year."
🧪
To sound formal or scientific
"The experiment was conducted."
Appendix: The Verb Transformation Trick
When a sentence changes from active to passive, the verb also gets a makeover! It always uses a helping verb (a form of "to be") and the past participle of the main verb.
How Verbs Change (Verb Tenses)
The secret is the formula: form of "to be" + past participle. The "to be" verb must match the tense of the original active verb.
Simple Tenses
Active (Present): ...prepares...
Passive (Present): ...is prepared...
Active (Past): ...prepared...
Passive (Past): ...was prepared...
Continuous Tenses
Active: ...is preparing...
Passive: ...is being prepared...
Active: ...was preparing...
Passive: ...was being prepared...
Perfect Tenses
Active: ...has prepared...
Passive: ...has been prepared...
Active: ...had prepared...
Passive: ...had been prepared...
Perfect Continuous Tenses
Active: ...has been preparing...
Passive: ...has been being prepared...
Active: ...had been preparing...
Passive: ...had been being prepared...
Sentence Superpowers: Working with Modals
Modals are special verbs like can, will, may, must, should, and ought to. They give verbs extra powers! The rule is simple: Modal + be + Past Participle.

| She can bake a cake. | A cake can be baked by her. |
| He will finish the project. | The project will be finished by him. |
