Active Voice and Passive Voice - Class 10 AP Board English

Active and Passive Voice in English Grammar

Active and passive voice are two ways of expressing actions in English sentences. The choice of voice affects the focus of the sentence, either on the subject performing the action (active) or on the object receiving the action (passive). Understanding the transformation rules and patterns is essential for exam success, especially for converting sentences between voices across different tenses and sentence types.

Active and Passive Voice in English Grammar

Active and passive voice are two ways of expressing actions in English sentences. The choice of voice affects the focus of the sentence, either on the subject performing the action (active) or on the object receiving the action (passive). Understanding the transformation rules and patterns is essential for exam success, especially for converting sentences between voices across different tenses and sentence types.

Core Definitions and Structure

Active voice emphasizes the subject performing the action, while passive voice highlights the object receiving the action. In active voice, the subject comes first, followed by the verb and then the object. In passive voice, the object moves to the subject position, the verb changes form, and the original subject is often introduced with "by".

• Active Voice Example: "He writes novels."
• Passive Voice Example: "Novels are written by him."
• Key Structure:
  • Active: Subject + Verb + Object
  • Passive: Object + Be form + Past Participle + (by Subject)

Fundamental Rules for Transformation

Transforming sentences from active to passive voice involves systematic changes in sentence structure and verb forms. The transcript outlines five main rules for this process.

• The object in the active voice becomes the subject in the passive voice.
• The subject in the active voice becomes the object (usually after "by") in the passive voice.
• The appropriate "be" form is used based on the tense and number (am, is, are, was, were, be, been, being).
• The main verb changes to its past participle (V3) form.
• Prepositions like "by", "with", "to" may be used depending on the sentence.

Be Forms and Verb Patterns

The correct "be" form is crucial in passive constructions and depends on the tense and subject number. The transcript provides explicit mappings and examples.

• Present Simple: am/is/are
• Past Simple: was/were
• Present Continuous: am/is/are + being
• Past Continuous: was/were + being
• Present Perfect: has/have + been
• Past Perfect: had + been
• Future Simple: will/shall + be
• Modal Verbs: can/could/must/should + be

Examples:

• "I play cricket every day." → "Cricket is played by me every day."
• "I am writing a letter." → "A letter is being written by me."
• "He has made kites." → "Kites have been made by him."
• "I wrote a letter." → "A letter was written by me."
• "I will write a letter tomorrow." → "A letter will be written by me tomorrow."

Past Participles and Common Confusions

Passive voice requires the past participle (V3) form of the main verb. The transcript highlights confusion between adjectives and verbs, and provides examples.

• "Ride" → "rode" (V2), "ridden" (V3)
• "Teach" → "taught" (V2/V3)
• "Good" is not a verb; its comparative forms are "better" and "best", not past participles.

Pitfall: Do not confuse adjectives or comparative forms with verb participles.

Handling Pronouns and Subject/Object Changes

When converting between voices, pronouns change form according to their function in the sentence. The transcript provides explicit mappings.

• "I" → "me"
• "He" → "him"
• "She" → "her"
• "They" → "them"
• "We" → "us"
• "It" → "it"
• "You" → "you"
• "Who" → "by whom"
• "Ing" form → "being"
• "Has/have/had" → "been"

Examples:

• "She knows me." → "I am known to her."
• "He made a century." → "A century was made by him."

Passive Voice Across Tenses

The transcript details passive voice construction for various tenses, with explicit examples and patterns.

• Simple Present: "Letters are not written by me daily."
• Simple Past: "A book was given to me by her."
• Present Continuous: "Classes are being watched by us on mobile."
• Past Continuous: "Lectures were being watched by Balasubrahmanyam and friends."
• Present Perfect: "A letter has been written by me just now."
• Past Perfect: "The letter had been posted by me."
• Simple Future: "A Maruti car will be given to the winner by them."
• Future Perfect: "A letter will have been written by him."

Imperative and Special Sentence Types

Imperative sentences (commands, requests, suggestions) are handled differently in passive voice. The transcript provides explicit patterns.

• For commands: "Open the door." → "Let the door be opened."
• For requests: "Please stop the chat." → "You are requested to stop the chat."
• For advice: "Don't waste time." → "You are ordered not to waste time."
• For sentences with "let": "Let" remains, followed by object and "be" + past participle.

Examples:

• "Bring the chair." → "Let the chair be brought."
• "Close the window." → "Let the window be closed."
• "Post this letter." → "Let this letter be posted."

Interrogative Sentences in Passive Voice

Questions require careful transformation, with helping verbs placed before the subject. The transcript provides explicit patterns.

• "Does he help you?" → "Are you helped by him?"
• "Did she write the letter?" → "Was the letter written by her?"
• "Is he cleaning the room?" → "Is the room being cleaned by him?"
• "Will they finish the task?" → "Will the task be finished by them?"
• "Who broke the glass?" → "By whom was the glass broken?"
• "Can you solve this problem?" → "Can this problem be solved by you?"
• "Should you submit the assignment?" → "Should the assignment be submitted by you?"

Sentences with Two Objects and Prepositions

When a sentence has two objects, either can be made the subject in passive voice. Prepositions are retained as per the original sentence.

• "She gave me a book." → "A book was given to me by her." or "I was given a book by her."
• "They elected Robin president." → "Robin was elected president."
• "The president appointed Rao governor." → "Rao was appointed governor."
• "They have objected to my proposal." → "My proposal has been objected to by them."
• "You must work for success." → "Success must be worked for by you."

Common Exam Patterns and Practice

The transcript emphasizes practicing transformations for all tenses, imperative, interrogative, and sentences with prepositions or two objects. Key points for exam readiness:

• Identify the tense and choose the correct "be" form.
• Change the main verb to its past participle.
• Adjust pronouns as per subject/object roles.
• Use "by", "to", "with", or other prepositions as required.
• For imperatives, use "let" or "you are requested/ordered/advised to".
• For interrogatives, place the helping verb before the subject.

Practice Examples:

• "I do not write letters daily." → "Letters are not written by me daily."
• "He has not received the letter." → "The letter has not been received by him so far."
• "You had not listened to the class." → "The class had not been listened to by you."
• "Do you speak Telugu?" → "Is Telugu spoken by you?"
• "Did the teacher explain the lesson?" → "Was the lesson explained by the teacher?"
