Active and Passive Voice

Active and Passive Voice

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Active voice places the doer of an action in the subject slot (Subject + Verb + Object), so “Rahul wrote the letter” clearly shows Rahul performing the action. Passive voice demotes the doer and promotes the receiver: “The letter was written by Rahul,” built from Object + be + past participle (V3) + by + agent.

Three rules carry almost every ECAT mark in this topic:

1. Only transitive verbs (verbs that take a direct object — write, build, teach, complete) can be flipped into passive. Intransitive verbs (happen, arrive, sleep) cannot.
2. The tense marker moves to the auxiliary be (is/am/are, was/were, will be, has been), while the main verb always stays as V3 (written, built, taught, completed).
3. The agent (by Rahul) is optional — drop it when the doer is unknown, obvious, or unimportant.

For ECAT English, expect 1–2 short transformation items (5–8 marks) testing Present Simple, Past Simple, and the modal can/must/should.

🟡 Standard — Regular Study (2d–2mo)

Standard content for students with a few days to months.

Core Pattern

Every passive construction follows one skeleton: Object + appropriate form of be + V3 (+ by + Agent). The challenge is matching the auxiliary to the original tense.

Tense-to-Auxiliary Conversion Table

Active Tense	Active Form	Passive Auxiliary + V3
Present Simple	writes / write	is / am / are + V3
Past Simple	wrote	was / were + V3
Future Simple	will write	will be + V3
Present Perfect	has/have written	has/have been + V3
Past Perfect	had written	had been + V3
Modal	can / must / should write	modal + be + V3

Interrogative and Imperative Shifts

In questions, the auxiliary hops in front of the new subject: Did he write the letter? → Was the letter written by him? — note was, not did. In imperatives, the model becomes Let + object + be + V3: Do the work. → Let the work be done. The imperative Let itself is retained in the passive form.

When to Use Passive

• Agent unknown or obvious: The bridge was built in 1990. (no one asks who).
• Focus on the action/receiver: scientific reports, news on mishaps (Three workers were injured).
• To vary sentence structure in writing, avoiding repetitive Subject–Verb–Object patterns.

Common ECAT Trap

Items often test whether you remembered to shift has/have into has/have been, not merely replace the verb. Students write The letter has written by Rahul, missing been. Always carry both halves of a perfect tense into the passive.

Verbs That Resist Passivisation

Not every transitive verb produces a natural passive. Stative uses of have, own, possess, resemble, suit, lack are often ungrammatical in passive (The house is owned by him ✓; He is lacked courage ✗). Reporting verbs with object clauses (They believe that he is honest) cannot be flipped directly — only the that-clause subject can be promoted with a “that” re-introducer: It is believed that he is honest.

Advanced Structures Tested

• Infinitival passive: He wants someone to help him → He wants to be helped.
• Gerundive passive: I dislike people interrupting me → I dislike being interrupted.
• Have / Get passive (causative): She got the car repaired (≈ she arranged for the repair).
• Modal perfect passive: The work should have been completed by now.

Common Mistakes to Avoid

• Using V1 instead of V3 (is write ✗ → is written ✓).
• Trying to passivise intransitive verbs (The accident happened cannot become Was happened the accident).
• Inserting a gerund after by as the agent (by working is a means, not an agent).
• Forgetting to promote an indirect object when the question setter wants A book was given to him rather than the ungrammatical He was given a book by me — both are accepted, but the indirect-object form preserves idiomatic word order.

Worked Example

Active: The engineers will test the new system next Monday. Step 1 — Identify object: the new system. Step 2 — Choose future passive auxiliary: will be. Step 3 — Keep V3: tested. Step 4 — Optional agent. Passive: The new system will be tested (by the engineers) next Monday. ✅

Two Practice Prompts

1. Convert: Someone has stolen my wallet. → My wallet has been stolen.
2. Convert: They are building a metro line in Lahore. → A metro line is being built in Lahore.
