Summary of "Active To Passive Voice | Transformation of Sentences | ICSE & ISC Grammar | Rules | Boards 2026"
Topic and purpose
- Lesson: How to transform sentences from active to passive voice (ICSE & ISC exam focus).
- Presenter’s guidance: When to use active (direct, crisp) vs passive (as a bystander/reporting an action).
Core idea / definition
Active voice: Subject performs the action — Subject + Verb + Object. Passive voice: Focus on the object or the event; the object of the active becomes the subject of the passive and the original subject can be introduced with by — Object + auxiliary be + past participle + by + Subject.
Passive often makes the speaker sound like an observer.
Key general rules (methodology)
- Subject–object shift: in passive, the active object usually becomes the grammatical subject; the active subject can become the agent introduced by “by”.
- The auxiliary (helping) verb be is essential in passive. Its form changes with tense:
- Present simple: is / am / are
- Past simple: was / were
- Perfects: been
- Continuous/passive continuous: being
- The main verb in passive must be the past participle (V3).
- Pronouns change when converting:
- I → me, we → us, you → you, it → it, they → them, he → him, she → her
- Place negation (not) after the auxiliary (e.g., was not completed).
- Agent omission: omit the agent (by …) when it is unknown, obvious, or unnecessary (e.g., “My bicycle has been stolen.” / “English is spoken all over the world.”).
Detailed structures, examples and instructions by tense/type
1) Simple tenses
-
Present Simple
-
Active: Subject + V1 (s/es for 3rd person sing.) + Object Example: She writes beautiful poems.
-
Passive: Object + is/am/are + V3 (+ by + Subject) Example: Beautiful poems are written by her.
-
-
Past Simple
-
Active: Subject + V2 + Object Example: The storm destroyed many houses.
-
Passive: Object + was/were + V3 (+ by + Subject) Example: Many houses were destroyed by the storm.
-
-
Future Simple
- Active: Subject + will/shall + V1 + Object
- Passive: Object + will/shall be + V3 (+ by + Subject) Example: They will publish the book next month. → The book will be published by them next month.
2) Continuous tenses
-
Present Continuous
- Active: Subject + is/am/are + V1+ing + Object
- Passive: Object + is/am/are being + V3 (+ by + Subject) Example: They are building new bridges → New bridges are being built by them.
-
Past Continuous
- Active: Subject + was/were + V1+ing + Object
- Passive: Object + was/were being + V3 (+ by + Subject) Example: The chef was cooking dinner when I arrived → Dinner was being cooked by the chef.
-
Future Continuous
- Passive forms are rare/awkward and subtitles are inconsistent; treat with caution.
3) Perfect tenses
-
Present Perfect
- Active: Subject + has/have + V3 + Object
- Passive: Object + has/have been + V3 (+ by + Subject) Example: He has broken the glass → The glass has been broken by him.
-
Past Perfect
- Passive: Object + had been + V3 (+ by + Subject) Example: The team had won the match → The match had been won by the team.
-
Future Perfect
- Active: Subject + will/shall have + V3 + Object
- Passive: Object + will/shall have been + V3 (+ by + Subject) Example: She will have completed her project → Her project will have been completed by tomorrow.
4) Perfect continuous tenses
- Many continuous/perfect continuous forms (e.g., present perfect continuous, past perfect continuous) are not normally used in passive because they emphasize duration or ongoing action rather than a resultant state. The subtitles contain inconsistencies here, so consult a grammar reference for edge cases.
5) Modal verbs (can, may, must, should, etc.)
- Active: Subject + modal + V1 + Object
- Passive: Object + modal + be + V3 (+ by + Subject) Example: You must follow the rules strictly → Rules must be followed strictly by you. Example: She can solve this problem easily → This problem can be solved easily by her.
6) Negative sentences
-
Put not after the auxiliary in the passive.
-
Active: He did not complete the task on time. Passive: The task was not completed on time by him.
-
Future negative: She will not accept the invitation. Passive: The invitation will not be accepted by her.
-
Present perfect negative: She has not finished. Passive structure: (Object) has not been + V3.
-
7) Interrogative sentences (questions)
- Move the auxiliary before the subject (standard question formation in passive).
- Present: Does she write a letter? → Is a letter written by her?
- Past: Did she write the letter? → Was the letter written by her?
- Future: Will they organize the event tomorrow? → Will the event be organized tomorrow by them?
- Modal: Should I attend the meeting? → Should the meeting be attended by me?
- Check subject–number to choose is/are or was/were.
8) Imperatives (commands / requests)
-
Use let + object + be + past participle.
- Active: Switch off the lights immediately. Passive: Let the lights be switched off immediately.
-
Negative imperative:
- Active: Do not disturb the class. Passive: Let the class not be disturbed.
-
Avoid incorrect word order (e.g., don’t say “let the light switched be off”).
Other practical tips & reminders
- Always change pronouns appropriately.
- Always use the correct form of be for tense and number agreement.
- Main verb in passive must be the past participle (V3).
- In many contexts the agent (by + subject) can be omitted if it is obvious or unimportant.
- Watch for subtitle errors/inconsistencies: the video sometimes contradicts itself (e.g., saying some tenses have no passive but earlier giving future perfect passive examples). Use a standard grammar reference if in doubt.
