Active Voice: Rewriting the Sentence

The task is to convert a sentence from passive voice to active voice. The original sentence provided is: "Her birthday is being celebrated by her."

Understanding Passive and Active Voice

• Passive Voice: The subject of the sentence receives the action. The structure often includes a form of "to be" + past participle, and the agent (doer of the action) might be mentioned using "by".
• Active Voice: The subject of the sentence performs the action. The structure is typically Subject + Verb + Object.

Analyzing the Original Sentence

Let's break down the given passive sentence:

• Subject: "Her birthday" (receives the action)
• Verb Phrase: "is being celebrated" (This is in the Present Continuous Tense, passive form)
• Agent: "by her" (the one performing the action)

Converting to Active Voice

To change this to active voice, we follow these steps:

1. Identify the agent in the passive sentence ("her") and make it the subject of the active sentence. So, "her" becomes "She".
2. Identify the verb phrase ("is being celebrated"). Keep the same tense (Present Continuous) but change it to the active form. The active form of "is being celebrated" is "is celebrating".
3. The subject of the passive sentence ("Her birthday") becomes the object of the active sentence.

Combining these steps, the active voice sentence becomes: "She is celebrating her birthday."

Comparing with Options

Let's examine the given options:

• Option 1: "She is celebrating her birthday" - This matches our converted sentence.
• Option 2: "She was celebrating her birthday" - This changes the tense to Past Continuous.
• Option 3: "She has celebrating her birthday" - This is grammatically incorrect ("has celebrated" would be correct for Present Perfect).
• Option 4: "She had celebrated her birthday" - This changes the tense to Past Perfect.

Therefore, Option 1 is the correct active voice transformation of the original sentence.
