Choose the suitable option that expresses the given Active Voice sentence in the Passive Voice.
The Teacher corrects our notebook.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Our notebook is corrected by the teacher.
Active to passive voice:
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | our notebook | Our notebook | “Our notebook” moves to the front. |
| Tense kept | corrects | is corrected | Be + past participle, in the same tense: simple present “corrects” becomes “is corrected” (singular subject “notebook”). |
| Agent (by ...) | The Teacher | by the teacher | The doer goes to the end as “by the teacher”. |
| Full sentence | The Teacher corrects our notebook. | Our notebook is corrected by the teacher. |
Example: The post is delivered by the postman every morning.
Why the Other Options are Incorrect?
Option 2: Our notebook was corrected by the teacher. — Incorrect. "Was corrected" is the simple past. The active sentence is in the simple present.
Option 3: Our notebook had been corrected by the teacher. — Incorrect. "Had been corrected" is the past perfect, a change of tense.
Option 4: Our notebook is being corrected by the teacher. — Incorrect. "Is being corrected" is the passive of the present continuous ("is correcting"), not of "corrects".
