Advanced Active Voice Worksheet for English language practice.

Let’s go through each sentence one by one. The goal is to change passive voice sentences into active voice. That means we want the subject (the doer of the action) to come first, and make sure they’re doing the verb — not having something done to them.

1. The girl was bitten by the dog.

Passive: “was bitten” → someone did the biting.
Who? The dog.
So in active voice: The dog bit the girl.

✔ Check: Subject = dog, Verb = bit, Object = girl → makes sense.

---

2. Research will be presented by Einstein at the conference.

Passive: “will be presented” → who presents? Einstein.
Active: Einstein will present research at the conference.

✔ Check: Einstein (subject) does the presenting → correct.

---

3. The chunks of dirt will be removed from the street by clean-up teams.

Passive: “will be removed” → who removes? Clean-up teams.
Active: Clean-up teams will remove the chunks of dirt from the street.

✔ Check: Teams do the removing → good.

4. The results will be published in the journal.

This one doesn’t say *who* publishes it. But we can still make it active by using a general subject like “they” or “the editors.” Since it’s common in publishing, let’s use “They” as the subject.

Active: They will publish the results in the journal.

Alternatively, if you want to keep it neutral but still active:
→ The journal will publish the results. (if the journal is the publisher)

But since the original didn’t specify, “They” is safe and grammatically correct for active voice.

✔ Let’s go with: They will publish the results in the journal.

*(Note: Some teachers prefer specifying an agent even if implied — so “They” works fine here.)*

5. The book is being read by the class.

Passive: “is being read” → who reads? The class.
Active: The class is reading the book.

✔ Simple swap — perfect.

6. It is believed by the candidate that a ceiling must be placed on the budget by Congress.

This has two passive parts:
- “It is believed by the candidate” → Candidate believes it.
- “a ceiling must be placed... by Congress” → Congress places the ceiling.

We need to fix both.

First part: Instead of “It is believed by the candidate,” say → The candidate believes...

Second part: Instead of “must be placed by Congress,” say → Congress must place...

Put together:
The candidate believes that Congress must place a ceiling on the budget.

✔ Both verbs are now active: “believes” and “place” — subjects doing actions.

7. It was earlier demonstrated that heart attacks can be caused by high stress.

Again, two passive ideas:
- “It was demonstrated” → Someone demonstrated it. We don’t know who, so we can use “Researchers” or “Scientists” — or just “Someone.” But better to pick a logical subject. In science contexts, “Researchers” is standard.
- “can be caused by high stress” → This is tricky. Actually, this part is already describing cause-effect. To make it active: “High stress can cause heart attacks.”

So full active version:
Researchers earlier demonstrated that high stress can cause heart attacks.

✔ Now: Researchers (subject) demonstrated (verb), and high stress (subject) causes (verb) heart attacks → all active!
