Active and Passive Voice: Master the Art of Sentence Transformation
Have you ever wondered why we say “The teacher explained the lesson” in one sentence and “The lesson was explained by the teacher” in another? Both sentences convey the same basic message, but their focus is different!
Welcome to the world of Active and Passive Voice, an essential part of English grammar that helps us write clearly, effectively, and confidently.
Let's understand the rules, explore examples, and practise changing active sentences into passive sentences.
1. What Are Active and Passive Voice?
Active Voice
In active voice, the subject performs the action expressed by the verb.
Example: Geeta writes a letter.
Subject: Geeta
Verb: writes
Object: a letter
The sentence focuses on the person performing the action.
Passive Voice
In passive voice, the subject receives the action expressed by the verb.
Example: A letter is written by Geeta.
Subject: A letter
Verb: is written
Doer of the action: Geeta
The focus shifts from the person performing the action to the object receiving it.
Compare the Two!
| Active Voice | Passive Voice |
|---|---|
| The girl caught the ball. | The ball was caught by the girl. |
| The president made an announcement. | An announcement was made by the president. |
| The teacher explains the lesson. | The lesson is explained by the teacher. |
| The students completed the assignment. | The assignment was completed by the students. |
Remember: Active voice highlights who does the action, while passive voice highlights what receives the action.
2. The Golden Formula
Changing active voice into passive voice becomes easier when you remember these two structures.
Active Voice:
Subject + Verb + Object
Passive Voice:
Object + Appropriate Form of Be + V³ + (by + Subject)
Here, V³ refers to the past participle, such as written, eaten, completed, prepared, or submitted.
Example
Active: Riya prepares breakfast.
Passive: Breakfast is prepared by Riya.
Notice how breakfast, the object of the active sentence, becomes the subject of the passive sentence.
Three Important Steps
Move the object of the active sentence to the beginning.
Use the appropriate helping verb and the past participle (V³).
Add by + doer when necessary.
Grammar Tip: The helping verb depends on the tense and the new subject. For example, we say “The letter is written” but “The letters are written.”
3. Converting Active into Passive Voice: Three Important Present Tenses
Let's explore the rules for the Simple Present, Present Continuous, and Present Perfect tenses.
A. Simple Present Tense
Active Voice Structure:
Subject + V¹ (s/es) + Object
Passive Voice Structure:
Object + am/is/are + V³ + (by + Subject)
Example:
Active: Geeta writes a letter.
Passive: A letter is written by Geeta.
More Examples:
Active: He cleans the room.
Passive: The room is cleaned by him.Active: They play cricket.
Passive: Cricket is played by them.Active: The teacher explains the lesson.
Passive: The lesson is explained by the teacher.
Remember:
Use is with singular subjects.
Use are with plural subjects.
Use am with I.
B. Present Continuous Tense
This tense describes an action that is happening at the moment of speaking.
Active Voice Structure:
Subject + am/is/are + V-ing + Object
Passive Voice Structure:
Object + am/is/are + being + V³ + (by + Subject)
Example:
Active: Geeta is writing a letter.
Passive: A letter is being written by Geeta.
More Examples:
Active: She is cooking dinner.
Passive: Dinner is being cooked by her.Active: They are painting the wall.
Passive: The wall is being painted by them.Active: The workers are repairing the road.
Passive: The road is being repaired by the workers.
Remember: The word being is essential when converting the Present Continuous tense into passive voice.
C. Present Perfect Tense
This tense describes an action that has been completed or has a connection with the present.
Active Voice Structure:
Subject + has/have + V³ + Object
Passive Voice Structure:
Object + has/have + been + V³ + (by + Subject)
Example:
Active: Geeta has written a letter.
Passive: A letter has been written by Geeta.
More Examples:
Active: He has completed the work.
Passive: The work has been completed by him.Active: They have planted trees.
Passive: Trees have been planted by them.Active: The students have submitted their assignments.
Passive: The assignments have been submitted by the students.
Remember:
Use has been with singular subjects.
Use have been with plural subjects and I/you/we/they.
D. Present Perfect Continuous Tense
The Present Perfect Continuous describes an action that started in the past and continued for some time, possibly up to the present.
Active Voice Structure:
Subject + has/have been + V-ing + Object
Example:
Active: Geeta has been writing a letter for an hour.
In standard English, passive constructions of this tense are grammatically possible in some contexts, but they are uncommon and often awkward. For basic grammar exercises, the passive form is generally avoided.
Remember: Focus on the three commonly taught transformations above when practising present-tense passive voice.
4. When Should You Use Active and Passive Voice?
Both forms are useful, but the best choice depends on your purpose.
Use Active Voice When You Want to:
Make your writing direct and clear.
Emphasise the person performing the action.
Create a lively and engaging tone.
Avoid unnecessarily long sentences.
Examples:
The marketing director launched a new campaign.
The scientist discovered a new protein.
The police arrested the suspect.
Use Passive Voice When You Want to:
Emphasise the action or its receiver.
Avoid mentioning an unknown or unimportant doer.
Maintain focus on the subject under discussion.
Use a suitable formal or academic style.
Examples:
The laptop was stolen last night.
The deadline has been moved to next Tuesday.
The book was published last year.
All tickets must be purchased in advance.
Writing Tip: Passive voice is particularly useful in some scientific reports and formal documents. However, active voice is often clearer when the doer of an action matters.
