Active & Passive Voice

Active & Passive Voice

🟢 Lite

Key Rule / Formula

Active: Subject does the action → Passive: Subject receives the action. Swap object to subject position, move original subject to the end with “by,” and change verb to form of “be” + past participle.

Memory Trick

“Agent first, patient last” — In active, the doer comes first. In passive, the receiver comes first. “The cat ate the rat” (active) → “The rat was eaten by the cat” (passive).

1-Sentence Summary

SSC asks you to convert sentences between Active and Passive voice — the core skill is verb form changes (is/are/am/was/were/been/being + past participle) and swapping subject/object positions.

Quick Example

Q: Convert to Passive: “She writes letters.” A: “Letters are written by her.” — Object “letters” becomes subject, verb becomes “are written,” original subject becomes object with “by.”

🟡 Standard

Concept

Voice in English grammar tells us whether the subject performs the action (Active) or receives it (Passive). In the active voice, the subject is the agent — “The manager approved the report.” In the passive voice, the subject is the patient — “The report was approved by the manager.”

To convert active to passive: move the object to subject position, move the subject to the end preceded by “by,” and change the verb to a form of “be” + past participle. The tense of “be” matches the original verb’s tense, and the past participle stays the same.

Passive voice is the standard in formal, official, and administrative English — government communications, scientific writing, and news reports frequently use it. SSC tests voice because clerical and administrative roles require strong command of both forms.

Key Points

• Tense conversion chart:
  • Present Simple: “writes” → “is written”
  • Past Simple: “wrote” → “was written”
  • Present Continuous: “is writing” → “is being written”
  • Present Perfect: “has written” → “has been written”
  • Past Perfect: “had written” → “had been written”
  • Future Simple: “will write” → “will be written”
• Imperative sentences: “Close the door” → “Let the door be closed” or “You are requested to close the door”
• Modal verbs: “can write” → “can be written”; “must submit” → “must be submitted”
• Omit “by agent” when the agent is unknown, obvious, or unimportant — “The report was submitted yesterday” (no by-agent needed)

Worked Example

Q: Change to Passive: “The committee has submitted the report.” Approach: Identify tense = Present Perfect. Object = “the report.” Move object to subject, add “by the committee,” change verb to “has been submitted.” Answer: “The report has been submitted by the committee.”

SSC Pattern / Tips

• 2–3 questions per paper — mix of active-to-passive and passive-to-active
• Sentences with two objects: either object can become the new subject. Prefer indirect object as subject — “She gave me a book” → “I was given a book by her” (more natural than “A book was given to me by her”)
• Modal passive: keep modal before “be” and use V3 after — “should be done,” “must be submitted,” “could have been finished”
• Eliminate options where the tense of “be” doesn’t match the original verb’s tense

Full Concept

Voice is a grammatical category that reveals the relationship between the subject and the action of the verb. The active voice foregrounds the agent — the person or thing doing something. The passive voice foregrounds the patient — the person or thing being acted upon. English allows both, and the choice reflects emphasis, style, and pragmatic intent rather than being arbitrary.

The passive construction follows this formula: Subject + form of “be” + past participle (V3) + (by + agent). The form of “be” carries tense and aspect. The past participle carries the lexical meaning. Together they form a verb phrase structurally different from the active but semantically equivalent.

SSC CGL tests voice in two formats: (1) direct active-to-passive or passive-to-active conversion, and (2) error-spotting with one correct voice conversion option. You must be fluent in both directions.

Passive voice is the default register of institutional writing — government orders, official memoranda, scientific findings, and news reports use it to foreground the action and its outcome rather than the actor. This is not stylistic preference but functional necessity in bureaucratic communication.

SSC CGL Deep Analysis

• Question frequency: 1–3 questions per paper; mix of directions
• Most tested tenses: Present Simple, Past Simple, Present Perfect (in that order)
• Common format: Sentence given; four options show possible conversions; pick the grammatically correct one
• Difficulty: Easy to Medium; the mechanical rule is straightforward, but compound sentences and double-object constructions trip students
• Imperative passive is a recurring favourite: “Open the window” → “You are requested to open the window” / “Let the window be opened”
• Trend from 2022: Questions now occasionally involve embedded passive within reported speech constructions, requiring you to identify passive form within a larger sentence structure

High-Scoring Strategy

1. Always identify the tense first — Write the correct form of “be” beside the original verb’s tense before doing anything else. This anchors your conversion.
2. Identify the object(s) — Single object → becomes new subject. Double object (direct + indirect) → either can become new subject. Prefer indirect object as new subject for naturalness.
3. For double-object sentences: “She told him a story” → “He was told a story by her” (natural) vs “A story was told to him by her” (grammatical but awkward). SSC often includes the awkward option.
4. Modal passive: Keep modal before “be,” use V3 after — “must be done,” “can be achieved,” “should be submitted.”
5. Time tip: Spend 20–30 seconds per question. If conversion is correct in one option and you can’t find the error in others, trust the first correct-looking option and move on.

SSC-Level Practice

Q1: (SSC CGL 2022) Change to Active: “The report was submitted by the team.” (A) The team submitted the report (B) The team has submitted the report (C) The team had submitted the report (D) The team submits the report Answer: (A) The team submitted the report — Past Simple passive “was submitted” → Past Simple active “submitted.” No perfect or continuous marker, so no extra tense baggage.

Q2: (SSC CGL 2021) Convert to Passive: “Could you please lift this box?” (A) Could this box be lifted by you? (B) Could this box be lifted? (C) Can this box be lifted by you? (D) Could this box has been lifted? Answer: (B) Could this box be lifted? — Imperative “could you please” converts to passive with “could” retained. Object “box” becomes subject. “By you” is unnecessary and awkward in passive imperatives.

Q3: Change to Passive: “Everyone knows him.” (A) He is known by everyone (B) He is known everyone (C) He is known of everyone (D) He is known to everyone Answer: (A) He is known by everyone — “Everyone” is indefinite. In passive, “by everyone” correctly identifies the knowers. “Known of” and “known to everyone” are not standard passive constructions for this sense.

Common Traps

• Trap 1 — Tense mismatch on “be”: “has written” → wrong: “is written” (no) / correct: “has been written.” Students forget “been” in perfect passive forms.
• Trap 2 — Wrong past participle: Irregular verbs — “write/wrote/written,” “sing/sang/sung,” “know/knew/known.” SSC uses the irregular V3 to trap those who default to past tense.
• Trap 3 — Omitting “by” when needed for meaning: “He was killed” implies someone killed him. “He killed” is a different sentence. Removing the agent doesn’t remove the implication.
• Trap 4 — Double-object wrong choice: “She gave me a book” → “I was given a book by her” (preferred) vs “A book was given to me by her” (awkward). SSC includes the awkward option as a distractor.
