To convert a sentence from passive voice to active voice, we need to identify the subject, verb, and object in the passive sentence and rearrange them into the active structure, where the subject performs the action. Let's go through the steps to solve the given question:
- Identify the Components of the Passive Sentence:
- Passive Sentence: "Our home-work shall have been completed by us."
- Subject (in the passive form): "our home-work"
- Verb: "shall have been completed"
- Agent performing the action (object in passive form): "us" (which converts to "we" in active voice)
- Formulate the Active Voice Sentence:
- Convert "us" (object in passive) to "we" (subject in active).
- Rearrange the sentence to have "we" as the subject performing the action.
- Change the verb form appropriately: "shall have been completed" becomes "shall have completed."
- Construct the Active Sentence:
- Active Sentence: "We shall have completed our home-work."
- Verification:
- Check if the sentence maintains the same meaning: In both sentences, "home-work" is completed by "us" or "we", ensuring consistency.
The correct active voice sentence is We shall have completed our home-work.
Let's evaluate the given options:
- Option 1: "We shall have been completed our home-work" - This option is grammatically incorrect and does not correctly convert the passive voice into active voice.
- Option 2: "We shall have completed their home-work" - The object "our home-work" is incorrectly replaced with "their home-work", which changes the meaning.
- Option 3: "We shall have completed our home-work" - This is the correct conversion, as explained above.
- Option 4: "They shall have completed our home-work" - The subject is incorrectly changed to "they" instead of "we".
Therefore, the correct answer is Option 3: We shall have completed our home-work.
