Active and Passive Voice is an essential grammar topic frequently asked in the English section of NDA and CDS examinations. Questions from this topic evaluate a candidate’s understanding of sentence structure, verb forms, and grammatical accuracy. In the English Live Class 2 conducted for NDA & CDS 1 2026 (Live Batch 2), candidates practiced multiple-choice questions based on the rules required for converting sentences from Active Voice to Passive Voice and vice versa.
This session focused on strengthening the conceptual understanding of voice transformation while solving exam-oriented MCQs similar to those asked in defence examinations. By practicing such questions, aspirants learned how to identify the correct sentence structure and apply grammatical rules effectively.
Understanding Active and Passive Voice
In English grammar, voice refers to the form of a verb that indicates whether the subject performs the action or receives the action.
Active Voice is used when the subject performs the action.
Example:
The officer completed the mission.
Passive Voice is used when the subject receives the action.
Example:
The mission was completed by the officer.
In defence examinations, candidates are often asked to identify the correct passive form of a sentence or convert a passive sentence into its active form while maintaining grammatical accuracy.
Key Rules of Conversion Covered in the Live Class
- Interchanging Subject and Object
The first step in converting an active sentence into passive voice is to interchange the subject and the object.
Example:
Active: The soldiers protected the border.
Passive: The border was protected by the soldiers.
The object of the active sentence becomes the subject of the passive sentence.
- Correct Use of Auxiliary Verb
In passive voice, an appropriate form of the auxiliary verb “be” (is, am, are, was, were, be, been, being) must be used depending on the tense of the sentence.
Example:
Active: She writes a letter.
Passive: A letter is written by her.
- Use of Past Participle (V3 Form)
The main verb in passive voice always appears in its past participle form.
Example:
Active: They built the bridge.
Passive: The bridge was built by them.
- Use of “By + Doer”
The doer of the action is introduced by the preposition “by” in passive voice. However, in some sentences, the doer may be omitted if it is obvious or not important.
Example:
Active: Someone stole the documents.
Passive: The documents were stolen.
- Maintaining the Correct Tense
While converting sentences from active to passive voice, the tense of the sentence must remain unchanged.
Example:
Active: The teacher is explaining the lesson.
Passive: The lesson is being explained by the teacher.
During the live class, special attention was given to identifying the tense of the original sentence before performing the transformation.
