Why bother with Active and Passive Voice?
Ever wondered why a sentence sometimes starts with "The ball was kicked" instead of "She kicked the ball"? Knowing both forms helps you sound natural and ace those ICSE English exams.
💡 In Simple Words: Active voice shows who does the action first, like "Tom paints a picture." Passive voice flips it, so the focus is on the picture: "A picture is painted by Tom." Both are correct; you just choose the one the question asks for.
What is Active Voice?
In an active sentence, the subject (the doer) comes first, followed by the verb (action word) and then the object (what the action hits). Think of it as a simple recipe: Chef → mixes → batter. The chef is the subject, mixes is the verb, batter is the object.
What is Passive Voice?
Passive voice flips the order: the object becomes the new subject, the verb changes form, and the original subject may appear after the word "by" (or be omitted). Using the same recipe, it becomes: Batter → is mixed → by the chef. The focus shifts to the batter.
How to Change Active to Passive – Step by Step
Follow these five easy steps, and you’ll never get stuck.
- Step 1: Find the object (the thing receiving the action).
- Step 2: Move that object to the front – it becomes the new subject.
- Step 3: Choose the correct form of the verb "to be" (am, is, are, was, were, etc.) that matches the new subject’s tense.
- Step 4: Add the past participle (the verb’s third‑form, like "written," "built," "eaten").
- Step 5: If the original subject is needed, attach it after "by".
Worked Example 1
Active: The teacher (subject) explained (verb) the lesson (object).
Passive: The lesson (new subject) was (to‑be) explained (past participle) by the teacher (optional).
Worked Example 2 – Different Tense
Active: The engineers will design the bridge.
Passive: The bridge will be designed by the engineers.
Common Mistakes to Avoid
- Using the wrong form of "to be." For present simple, use "is/are"; for past simple, use "was/were".
- Leaving out the past participle. "The cake was" is incomplete – you need "baked," "eaten," etc.
- Changing the meaning. "She broke the vase" → "The vase was broken by her" is fine, but "She broke the vase" → "The vase was broke" is wrong.
- Adding extra words. The passive sentence should be as concise as the active one.
Active vs Passive: Quick Comparison Table
| Aspect | Active Voice | Passive Voice |
|---|---|---|
| Focus | Doer of the action | Receiver of the action |
| Structure | Subject + Verb + Object | Object + Form of “to be” + Past Participle + (by Subject) |
| Typical Use | Storytelling, clear actions | When the doer is unknown or less important |
Tips for ICSE Exams
- Read the sentence carefully; underline the verb and the object.
- Check the tense first – it decides the "to be" form.
- Remember that some verbs don’t change in the past participle (e.g., "put" stays "put").
- Practice with the exact wording used in past ICSE papers – they love sentences like "The police arrested the thief."
