Understanding Active and Passive Voice
- Definition: The subject performs the action expressed by the verb.
- Structure: Subject + Verb + Object
- Example: "The teacher (subject) explains (verb) the lesson (object)."
Passive Voice:
- Definition: The object of an active sentence becomes the subject of the passive sentence. The focus is on the action or the recipient of the action.
- Structure: Subject (receiver of the action) + Form of "to be" + Past Participle + (by + Agent)
- Example: "The lesson (subject) is explained (verb) by the teacher (agent)."

5. Additional Tips
Active Voice:
- Focus Shift: In passive voice, the emphasis is often on the action or the recipient, not on who performed the action.
- Clarity: Use "by" to specify the doer of the action if it's important or relevant to the context.
- Natural Usage: Some sentences may not naturally or effectively convert to passive voice, particularly if the doer of the action is unknown or not important.

- Natural Flow: Ensure that the passive voice construction does not make the sentence cumbersome or less clear than the active voice.
