- ๐ Worksheet: Active & Passive Voice
Voice is the form of a verb that shows whether the subject performs the action (active) or receives the action (passive). In active voice, the subject is the doer. In passive voice, the subject is the receiver. Mastering voice change is essential for formal writing, scientific reports, and many exam questions in CBSE and UP Board grammar sections.
Riya wrote a letter.
Passive Voice: Subject receives the action.
A letter was written by Riya.
Active Voice vs Passive Voice — Key Differences
| Feature | Active Voice | Passive Voice |
|---|---|---|
| Subject | Doer of action | Receiver of action |
| Focus | Who did it | What happened / What was done |
| Verb Form | Various tenses | be + past participle |
| Example | The cat chased the mouse. | The mouse was chased by the cat. |
General Rules for Changing Active to Passive
- Identify the object of the active sentence. It becomes the subject of the passive sentence.
- Use the correct form of "be" (am, is, are, was, were, being, been) according to the tense.
- Use the past participle (V3) of the main verb.
- The subject of the active sentence becomes the agent in the passive, introduced by "by". (Optional if the doer is unknown or unimportant.)
Passive Voice in Simple Tenses
| Tense | Active Structure | Passive Structure | Example |
|---|---|---|---|
| Simple Present | V1 / V1+s/es | am/is/are + V3 | She writes a letter. → A letter is written by her. |
| Simple Past | V2 | was/were + V3 | She wrote a letter. → A letter was written by her. |
| Simple Future | will/shall + V1 | will/shall + be + V3 | She will write a letter. → A letter will be written by her. |
Passive Voice in Continuous Tenses
| Tense | Active Structure | Passive Structure | Example |
|---|---|---|---|
| Present Continuous | am/is/are + V1+ing | am/is/are + being + V3 | She is writing a letter. → A letter is being written by her. |
| Past Continuous | was/were + V1+ing | was/were + being + V3 | She was writing a letter. → A letter was being written by her. |
| Future Continuous | will be + V1+ing | No passive | Avoid. Use active only. |
Passive Voice in Perfect Tenses
| Tense | Active Structure | Passive Structure | Example |
|---|---|---|---|
| Present Perfect | has/have + V3 | has/have + been + V3 | She has written a letter. → A letter has been written by her. |
| Past Perfect | had + V3 | had + been + V3 | She had written a letter. → A letter had been written by her. |
| Future Perfect | will have + V3 | will have + been + V3 | She will have written a letter. → A letter will have been written by her. |
Passive Voice with Modal Auxiliaries
Structure: Modal + be + V3
- Active: We can solve this problem. → Passive: This problem can be solved.
- Active: She must finish the work. → Passive: The work must be finished.
- Active: You should obey your parents. → Passive: Your parents should be obeyed.
- Active: They might cancel the event. → Passive: The event might be cancelled.
Passive of Imperative Sentences (Commands/Requests)
Structure: Let + object + be + V3 (or simply be + V3).
- Active: Open the door. → Passive: Let the door be opened. / You are ordered to open the door.
- Active: Do not waste time. → Passive: Let time not be wasted. / You are advised not to waste time.
- Active: Please help me. → Passive: You are requested to help me.
Special Cases & Exceptions
- Intransitive verbs (verbs without an object) cannot be changed to passive. Example: She sleeps. (No passive)
- Verbs with two objects: Either object can become the subject.
Active: He gave me (indirect) a book (direct).
Passive 1: I was given a book by him.
Passive 2: A book was given to me by him. - Prepositional verbs: The preposition stays with the verb.
Active: They laughed at him. → Passive: He was laughed at. - Sentences with 'by' phrase omitted: When the doer is unknown, unimportant, or obvious.
Active: Someone stole my purse. → Passive: My purse was stolen. (No 'by someone')
Common Mistakes to Avoid
| Wrong ❌ | Right ✅ | Why? |
|---|---|---|
| A letter is wrote by her. | A letter is written by her. | Use past participle (V3), not past tense. |
| The work was being do. | The work was being done. | 'Being' is followed by V3. |
| Let the door opened. | Let the door be opened. | Imperative passive needs 'be'. |
| English is speaking worldwide. | English is spoken worldwide. | Passive requires 'be + V3'. |
| He was laughed. | He was laughed at. | Keep the preposition with the verb. |
