Difference Between Passive Voice to Active Voice — Exercise 1 (Tenses, Modals, Infinitive, Participle, Gerund, All English Grammar Included) Enrich Your Vocabulary
This practice set trains you to convert active sentences into correct passive forms across a wide range of tenses and modals (simple, continuous, perfect, perfect-continuous, modals + perfect, infinitive, participle, gerund, passive with causatives, and more). Each item gives an active sentence followed by four passive options — only one is correct. 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 each distractor is wrong. No verbs or questions repeat within this set — designed for thorough practice and strong 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. Passive: The itinerary will be finalized next week by the committee.
A) The committee will finalize the itinerary next week.
B) The itinerary will finalize next week by the committee.
C) The committee will be finalizing the itinerary next week.
D) The itinerary will have been finalized next week by the committee.
Verb (POS & meaning): finalize — verb. To finish arranging details.
Key POS: the itinerary (Passive subject → Active object), the committee (agent → Active subject), will be finalized (future passive).
A) Correct: Start with the by phrase: by the committee → that tells us the active subject is the committee.
The passive shows future action (will be finalized), so the active must be will finalize (simple future).
Option A exactly moves the committee to subject and uses will finalize — same time and meaning.
B) Wrong: keeps passive word order (wrong).
C) Wrong: changes aspect to continuous (means “ongoing”).
D) Wrong: uses future perfect passive (different meaning).

D) The team has completed the risk assessment before launch.
Verb: complete — verb. To finish something.
Key POS: had been completed (past perfect passive), by the team (agent).
A) Correct: Had been completed → past perfect passive. Convert to active by making the agent the subject (the team) and use past perfect: had completed.

Move management to subject: Management is reviewing the incident report right now.

Verb: prepare — verb. To make or cook something.
Key POS: had been being prepared (past perfect continuous passive), when the power failed (time clause).
A) Correct: The passive shows an action in progress before a past point (past perfect continuous). Convert to active: subject (chef) + had been preparing (past perfect continuous).
