He is punished by himself. (Change the voice)

The original sentence "He is punished by himself" is in the passive voice, indicating that the action of punishing is being performed on the subject 'He' by 'himself'. To change it to the active voice, we need to restructure the sentence so that the subject performs the action.

Here's a breakdown of the transformation:

• Identify the Agent: In the passive sentence, 'himself' is the agent performing the action. In active voice, this agent becomes the subject. Since 'himself' refers to 'He', 'He' becomes the subject of the active sentence.
• Identify the Verb Tense: The passive verb "is punished" is in the simple present tense. The active verb must also be in the simple present tense.
• Formulate the Active Verb: The active form of "is punished" for the subject 'He' is "punishes".
• Identify the Object: When a reflexive pronoun (like 'himself', 'herself', 'themselves') acts as the agent in a passive voice sentence, it typically becomes the object in the active voice.

Therefore, combining these elements, the active voice transformation of "He is punished by himself" is "He punishes himself." This construction clearly shows that 'He' is both the doer and the receiver of the action.
