NDA Active & Passive Voice

Active Voice: The subject performs the action

'Ram writes a letter.' Passive Voice: The action is performed on the subject

'A letter is written by Ram.' The key difference is WHO is doing the action versus WHO is receiving the action

Object of active voice becomes subject of passive voice 2. Subject of active voice becomes object with 'by' in passive voice 3. Verb changes to 'be + past participle' form 4. Tense remains the same in both voices

- Direct conversion (Active to Passive or vice versa) - Identifying correct passive form from options - Error detection in voice usage - Fill in the blanks with correct voice form SHORTCUT TRICK #1 - THE 'BY' TEST: If you can add 'by someone' at the end of the sentence meaningfully, it's likely passive voice. If it sounds odd, it's active voice. SHORTCUT TRICK #2 - TENSE PRESERVATION: The tense never changes during voice conversion. If active is present tense, passive will also be present tense. Only the verb form changes

TENSE STAYS THE SAME, only verb form changes. If the active sentence is in past tense, the passive will also be in past tense. Don't convert 'He wrote a letter' to 'A letter is written by him.' The correct answer is 'A letter was written by him.' Another major mistake is forgetting that some verbs cannot be made passive. Intransitive verbs (verbs without objects) like 'sleep', 'die', 'arrive' cannot be converted to passive voice

In SSC CGL, always read the entire sentence carefully. Look for time indicators (yesterday, tomorrow, always) to confirm the tense. This prevents the common error of wrong tense usage in voice conversion.
