Practice Of Active And Passive Voice | Sentence Control

If you’ve ever stared at a sentence and thought, “Why does this sound off?” there’s a good chance voice is part of the problem. Active voice and passive voice aren’t enemies. They’re tools. When you can flip between them on purpose, your writing gets cleaner, your meaning lands faster, and your sentences stop feeling tangled.

This lesson is built for practice, not theory. You’ll get simple rules, conversion steps you can reuse, and drills that feel like the ones that show up in school exams, IELTS writing, university assignments, and workplace emails.

What Active Voice Does

In active voice, the subject does the action. The sentence moves in a straight line: doer → action → receiver. That direct flow is why active voice often feels shorter and clearer.

Pattern: Subject + verb + object

• Maria finished the report.
• The dog chased the ball.
• Our team will review the plan.

Active voice works well when you want accountability, clarity, and pace. It’s also a solid default for most everyday writing.

What Passive Voice Does

In passive voice, the receiver of the action becomes the subject. The doer can appear later in a “by …” phrase, or it can be left out when the doer is unknown or not worth naming.

Pattern: Object + form of be + past participle (+ by + agent)

• The report was finished (by Maria).
• The ball was chased by the dog.
• The plan will be reviewed by our team.

Passive voice earns its place when the receiver matters more than the doer, when you don’t know who did it, or when the doer is obvious from context.

How To Spot Voice Fast

Here’s a quick check you can run in ten seconds:

1. Find the main verb.
2. Ask: “Who is doing this action?”
3. If the subject is the doer, it’s active.
4. If the subject receives the action, it’s passive.

Then do one more check for passive: look for a form of be (is/are/was/were/been/being) paired with a past participle (built, written, chosen, taken). That combo is a common passive marker, and it’s one reason passive is easy to detect during editing.

When Passive Voice Works Better

Some teachers treat passive voice like a mistake. That’s too blunt. Passive is normal in certain settings, and it can sound more natural than forcing every sentence into active.

Use Passive When The Receiver Deserves The Spotlight

If the thing affected by the action is what your reader cares about, passive can put it in the first position, where it’s easiest to see.

• My phone was stolen last night.
• The final results were published this morning.

Use Passive When The Doer Is Unknown

If you don’t know who did it, active voice can force awkward fillers like “someone” or “they.” Passive often reads cleaner.

• The window was broken during the storm.
• Your package has been delivered.

Use Passive For Process Writing

Lab reports, instructions, and formal descriptions often care more about the steps than the person doing them. Passive can keep attention on the process. If you want a clear, classroom-friendly explanation plus revision tips, Purdue OWL “Active and Passive Voice” lays it out with examples.

Practice Of Active And Passive Voice

Let’s get hands-on. You’ll convert sentences both ways, then you’ll learn how to pick the better choice for a goal. Treat this like gym reps: slow at first, then smoother.

Step List For Turning Active Into Passive

1. Circle the object in the active sentence. That becomes the new subject.
2. Lock the tense from the original verb.
3. Add the correct form of be for that tense.
4. Change the main verb to the past participle.
5. Add “by + agent” only when naming the doer helps the reader.

That “be + past participle” backbone is the core pattern learners should memorize. The British Council states it plainly and gives lots of model sentences for practice. British Council: “Active and passive voice”

Step List For Turning Passive Into Active

1. Find the agent (the “by …” phrase). If there isn’t one, choose a logical doer from the context.
2. Make that agent the subject.
3. Keep the original tense, then rebuild the verb in active form.
4. Make the old subject the object.

Table: Common Goals And The Voice That Fits

Use this table like a decision card while you practice. Pick your goal, then pick the voice that matches it.

Writing Goal	Active Voice Example	Passive Voice Example
Name the doer clearly	The manager approved the budget.	The budget was approved (by the manager).
Start with the receiver	Someone damaged the file.	The file was damaged.
Keep a formal tone	We collected the samples.	The samples were collected.
Reduce blame in a message	We lost your document.	Your document was misplaced.
Write instructions or methods	Heat the solution to 70°C.	The solution is heated to 70°C.
Report results	Researchers found a pattern.	A pattern was found.
Keep the topic in subject position	People speak Portuguese in Brazil.	Portuguese is spoken in Brazil.
Hide the doer when unknown	Someone stole my bike.	My bike was stolen.

Active And Passive Voice Practice With Exam Prompts

Now let’s train the skill that scores points: changing voice without breaking tense, meaning, or grammar. Don’t rush. Accuracy comes first. Speed follows.

Keep The Tense When You Switch

Many learners switch voice and accidentally switch time. Fix that by labeling the tense before you change anything. Write the tense name in the margin: present simple, past simple, present perfect, future, modal.

Present Simple

• Active: The shop sells fresh bread.
• Passive: Fresh bread is sold by the shop.

Past Simple

• Active: They repaired the bridge.
• Passive: The bridge was repaired.

Present Perfect

• Active: The team has completed the test.
• Passive: The test has been completed.

Future With Will

• Active: The committee will announce the decision.
• Passive: The decision will be announced.

Modals

With modals (can, must, should, may), the passive form is often: modal + be + past participle.

• Active: You must follow the rules.
• Passive: The rules must be followed.

Use “By” Only When It Adds Meaning

New writers sprinkle “by” everywhere. You don’t have to. If the doer is obvious, boring, or unknown, leave it out.

• Better: The tickets were sold out in one hour.
• Clunky: The tickets were sold out in one hour by people.

Watch These Common Slip-Ups

Most passive errors come from three spots: the wrong form of be, the wrong past participle, or a missing object in the original sentence.

• Be-form mismatch: “The letters is delivered” → “The letters are delivered.”
• Past participle errors: “was ate” → “was eaten.”
• Intransitive verbs: You can’t form a normal passive without an object. “He arrived late” has no object, so passive won’t work.

Drills That Build Real Control

Here’s a set of drills you can reuse for any topic. Do them in this order. Each drill targets one skill, so you don’t get overwhelmed.

Drill 1: Underline Subject, Verb, Object

Take five sentences from a book or article. Underline the subject once, the verb twice, and the object with a wavy line. If you can’t find an object, skip passive and keep it active.

Drill 2: Convert Only The Middle Clause

Long sentences can carry more than one clause. Instead of changing the whole thing, change only the clause that carries the main message.

• Active: The coach said the players followed the plan.
• Mixed: The coach said the plan was followed.

Drill 3: Rewrite For A Clearer Subject

Sometimes passive hides the real subject too much. Flip it back to active and name the doer.

• Passive: The deadline was missed.
• Active: The team missed the deadline.

Drill 4: Keep The Same First Word

This drill trains topic control. Start both versions with the same noun, then see which voice lets you keep that noun as the subject.

• Topic: “The policy …”
• Active: The policy protects users from spam.
• Passive: The policy is followed in all departments.

Table: Practice Set With Answers

Cover the third column with your hand, write your version, then compare. If yours is different but still grammatical and keeps meaning, you’re good.

Task	Sentence Prompt	One Clean Answer
Active → Passive (present simple)	The company ships orders daily.	Orders are shipped daily.
Active → Passive (past simple)	Lisa wrote the email last night.	The email was written last night.
Active → Passive (present perfect)	They have repaired the road.	The road has been repaired.
Active → Passive (modal)	You must submit the form today.	The form must be submitted today.
Passive → Active (agent given)	The prize was awarded by the jury.	The jury awarded the prize.
Passive → Active (agent missing)	The lights were turned off at 10 p.m.	The staff turned off the lights at 10 p.m.
Choose voice for clarity	The meeting minutes were sent. (Who?)	Rina sent the meeting minutes.
Choose voice for focus	Someone updated the schedule. (Focus: schedule)	The schedule was updated.

Edit Checklist For Voice

When you edit, you’re not hunting passive forms like they’re a crime. You’re checking whether each sentence points to the right subject and keeps the reader oriented.

Checklist Steps

1. Underline the subject in each sentence. Ask: is that the noun you want to feature?
2. Circle any be + past participle forms. Ask: does the sentence still feel clear without naming the doer?
3. If three or more passive sentences stack in a row, switch one or two back to active so the paragraph breathes.
4. In academic writing, keep passive where the method or result is the focus. In personal writing, lean active unless there’s a reason not to.

Mini Rewrite Demo

Here’s what a quick revision can look like.

• Before: The files were reviewed and the errors were corrected.
• After: The editor reviewed the files and corrected the errors.

Same meaning. Clearer doer. Fewer repeated passive verbs. That’s the whole game.

One Week Practice Plan

If you want steady progress, use a tiny daily routine. Ten minutes is enough if you stay consistent.

1. Day 1: Identify voice in 20 sentences.
2. Day 2: Convert 10 active sentences to passive.
3. Day 3: Convert 10 passive sentences to active.
4. Day 4: Mix tenses: present, past, perfect, future, modals.
5. Day 5: Write one paragraph in active, then rewrite it with a few passive choices where focus changes.
6. Day 6: Do the table practice set again, aiming for zero tense mistakes.
7. Day 7: Edit a real piece of your writing with the checklist above.

Stick with this for a week and you’ll start hearing voice problems before you even finish a sentence. That’s when writing gets easier.
