Exercise 10: Practice difference between Active to Passive across tense, modals, gerund, infinitive, participle & complete grammar set. Exam-style question with word meaning.
This practice set trains you to make correct passive forms sentences across a wide range of tenses and modals (simple, continuous, perfect, perfect-continuous, modals + perfect, infinitive, participle, gerund, passive with causatives, and more). Each question gives an active sentence followed by blanks for the passive voice — your job is to select & drop single-word option containers into the blanks. Every question includes the main verb (POS & short word meaning), key POS items, and a clear explanation for why the correct answer is right and why other options and distractors are wrong. No verbs or questions repeat within the full set — designed for thorough practice and strong English Grammar and Spoken English coverage of “passive voice,” “active to passive,” and tense-conversion queries.
English Grammar Definition: Passive Voice (Be + verb 3rd form)
- Form: be + verb 3rd form.
- Definition: Passive voice = Object of the active + appropriate form of be + past participle (+ by + agent) (agent optional).
- When to use: when the action or object is more important than the actor, or actor unknown/irrelevant.
- Form basics:
- Simple present passive: is/are + V3
- Simple past passive: was/were + V3
- Present perfect passive: has/have been + V3
- Future passive: will be + V3 or will have been + V3 (future perfect passive)
- Modal passive: modal + be + V3 or modal + have been + V3 (modal perfect passive)
- Passive of continuous forms: is/are being + V3; was/were being + V3; will be being + V3 (rare)
- Conversion tip: Identify the object of the active sentence — that becomes the subject of the passive. Match tense and auxiliary forms; preserve modals (can/will/must/should) using be or have been as needed.

Quiz Question, Answer and Explanation
Note: Do remember in the quiz box above, the questions and options will shuffle, so they won’t have the same sequence like 1, 2, 3, or A, B, C as below.
1. Active: They must improve the safety measures immediately.
Convert To Passive: The safety measures [[blank1]] [[blank2]] [[blank3]] immediately.
Options: must, be, improved, improve, should, were, would, been, improving
Verb (POS & meaning): improve — verb. To make better; must — modal expressing necessity.
Key POS: they (agent), must improve (modal obligation), the safety measures (object → subject).
Correct Passive (blanks): The safety measures [[must]] [[be]] [[improved]] immediately.
Explanation: Modal passive uses modal + be + V3; must expresses necessity/obligation in passive form. This forces emphasis on measures rather than actors.
Why distractors wrong: improve base form wrong; should different modal nuance; were wrong tense.
Trap/tip: Use strong modals for urgent passive instructions.
2. Active: They saw the mural being painted at dawn.
Convert To Passive: The mural [[blank1]] [[blank2]] [[blank3]] [[blank4]] at dawn.
Options: was, were, seen, being, painted, paint, painting, been, be, see, saw, had
Verb (POS & meaning): see — perception verb; paint — verb.
Key POS: they (agent), saw (past), the mural (object → subject), being painted (present participle passive sequence).
Correct Passive (blanks): The mural [[was]] [[seen]] [[being]] [[painted]] at dawn.
Explanation: Perception verbs can take passive forms with progressive aspect: was seen being + V3. This emphasizes both the observation and the ongoing action of painting.
Why distractors wrong: painted alone lacks the progressive observation nuance if placed incorrectly; were wrong agreement.
Trap/tip: Perception + progressive passive combos are advanced but important for nuance.
3. Active: Someone has vandalised the bus shelter.
Convert To Passive: The bus shelter [[blank1]] [[blank2]] [[blank3]].
Options: has, have, been, vandalised, vandalize, was, were, the, bus, shelter, by, someone
Verb (POS & meaning): vandalise — verb. To deliberately damage property.
Key POS: someone (agent), has vandalised (present perfect), the bus shelter (object → subject).
Correct Passive (blanks): The bus shelter [[has]] [[been]] [[vandalised]].
Explanation: Present perfect passive uses has/have been + V3 to show a past action with present relevance; singular shelter → has. The agent is optional.
Why distractors wrong: have wrong agreement; was/were wrong tense.
Trap/tip: Distinguish between present perfect passive (has been done) and simple past passive (was done).
4. Active: They will consider cancelling the concert if it rains.
Convert To Passive: Cancelling the concert will [[blank1]] [[blank2]] if it rains.
Options: will, be, considered, consider, being, been, considering
Verb (POS & meaning): consider — verb. To deliberate; cancel — verb.
Key POS: they (agent), will consider (future), cancelling the concert (gerund phrase → subject), conditional clause.
Correct Passive (blanks): Cancelling the concert will [[be]] [[considered]] if it rains.
Explanation: Future passive with gerund subject: will be considered. The conditional if it rains determines whether consideration will happen. Using the gerund as subject keeps focus on the action rather than actors.
Why distractors wrong: consider active; cancel V1 wrong form; will without be incomplete.
Trap/tip: Keep conditional clauses intact when converting to passive.
5. Active: They should have informed the staff before the meeting.
Convert To Passive: The staff [[blank1]] [[blank2]] [[blank3]] informed before the meeting.
Options: should, have, been, informed, inform, was, were, shall, would, had, be, being
Verb (POS & meaning): inform — verb. To give information.
Key POS: they (agent), should have informed (modal perfect), the staff (object → subject), before the meeting (time).
Correct Passive (blanks): The staff [[should]] [[have]] [[been]] informed before the meeting. (Add V3 informed if using 4 blanks)
Explanation: Modal perfect passive: modal + have + been + V3 expresses an obligation in the past that was expected to have been fulfilled. It emphasizes the staff as recipients of the information.
Why distractors wrong: was/were change modality; inform base form wrong; have been without modal lacks obligation nuance.
Trap/tip: For modal perfect passives, place each auxiliary in its own blank to preserve structure.
6. Active: Someone must have tampered with the evidence.
Convert To Passive: The evidence [[blank1]] [[blank2]] [[blank3]] tampered with.
Options: must, have, been, be, was, were, tampered, tamper, with, the, evidence, by
Verb (POS & meaning): tamper — verb. To interfere improperly.
Key POS: someone (agent), must have tampered (modal perfect), the evidence (object → subject).
Correct Passive (blanks): The evidence [[must]] [[have]] [[been]] tampered with. (Add V3 tampered as extra blank if desired.)
Explanation: Modal perfect passive (must + have + been + V3) expresses strong logical conclusion about a past action. The passive centers the evidence and the suspected interference.
Why distractors wrong: be misplaces auxiliary; was/were lose modal inference.
Trap/tip: Modal perfect passives are key in forensic/analytic contexts.
7. Active: The coach had his assistant demonstrate the drill. (causative/have)
Convert To Passive: His assistant [[blank1]] [[blank2]] to [[blank3]] the drill.
Options: was, had, made, have, demonstrated, demonstrate, been, being, make, has
Verb (POS & meaning): have — verb (causative/arrange); demonstrate — verb. To show how something is done.
Key POS: the coach (agent), had (causative past), his assistant (object → subject), demonstrate (bare infinitive).
Correct Passive (blanks): His assistant [[was]] [[made]] to [[demonstrate]] the drill. (Interpreting the causative as forcing: was made to demonstrate.)
Explanation: With causative have in forcing sense, passive typically converts to be + made + to + V1. If have meant arrange rather than force, paraphrasing is safer. Here we present the forcing interpretation for exam-style clarity.
Why distractors wrong: had alone is active; demonstrated (V3) would suggest completed action rather than causative forcing.
Trap/tip: Clarify the intended sense of have before converting; choose was made to for forcing meaning.
8. Active: Managers may appoint a panel to review the case.
Convert To Passive: A panel [[blank1]] [[blank2]] [[blank3]] to review the case.
Options: may, be, appointed, appoint, might, was, were, a, panel, to, review, case
Verb (POS & meaning): appoint — verb. To formally select. review — verb. To examine.
Key POS: managers (agent), may appoint (modal), a panel (object → subject), to review the case (purpose).
Correct Passive (blanks): A panel [[may]] [[be]] [[appointed]] to review the case.
Explanation: Modal passive with purpose infinitive: modal + be + V3, and the infinitive purpose phrase follows unchanged. This keeps the possibility and the intended function of the panel.
Why distractors wrong: appoint V1 incorrect; might alternative modal changes nuance.
Trap/tip: Test a variety of modals to practice subtle meaning shifts.
9. Active: People usually take photos of the sunset.
Convert To Passive: Photos of the sunset [[blank1]] [[blank2]] usually.
Options: are, is, taken, take, taking, photos, of, the, sunset, usually, by, people
Verb (POS & meaning): take — verb. To capture images.
Key POS: people (agent), take (present simple), photos of the sunset (object → subject), usually (adverb).
Correct Passive (blanks): Photos of the sunset [[are]] [[taken]] usually. (Better placement often: Photos of the sunset are usually taken.)
Explanation: Simple present passive with frequency adverb: are + V3 and adverb placement may vary; passive emphasizes photos rather than photographers.
Why distractors wrong: is wrong agreement for plural photos; taking V-ing changes aspect.
Trap/tip: Position adverbs naturally but ensure passive auxiliary and participle are correct.
10. Active: The director will have the script revised by the committee. (causative/have + passive agent)
Convert To Passive: The script will [[blank1]] [[blank2]] [[blank3]] by the committee.
Options: will, have, been, revised, revise, was, were, revising, be, being, has, had
Verb (POS & meaning): have — verb (causative/arrange); revise — verb. To alter for improvement.
Key POS: the director (agent), will have (future causative/arrangement), the script (object → subject), revised (past participle), by the committee (agent performing the revision).
Correct Passive (blanks): The script will [[have]] [[been]] [[revised]] by the committee.
Explanation: Future causative/arrangement with passive result uses will + have + been + V3 (future perfect passive). It shows that by a future point the committee will have completed revisions as arranged by the director. This form is common in formal/project timelines.
Why distractors wrong: was/were change tense; revise base form wrong; missing auxiliaries break the tense/aspect.
Trap/tip: For causative arrangements tied to future completion use will have been + V3 to express that completion before a future reference point.
