Difference Between Active and Passive Voice Practice — Exercise 2 (Tenses, Modals, Infinitive, Participle, & Gerund Included) Improve English with Word Power
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.
