Active and passive voice show how the subject of a sentence relates to the action. This cheat sheet helps students identify who is doing the action and decide which voice makes a sentence clearer. Students need this skill for essays, narratives, reports, and revision because voice affects clarity, emphasis, and style.
Understanding voice also helps writers avoid wordy or confusing sentences.
In active voice, the subject performs the action, as in The student solved the problem. In passive voice, the subject receives the action, as in The problem was solved by the student. Passive voice often uses a form of be plus a past participle, but not every sentence with be is passive.
Strong writers choose active voice for directness and passive voice when the receiver of the action matters more than the doer.
Key Facts
- Active voice follows the pattern subject + action verb + object, as in The coach praised the team.
- Passive voice often follows the pattern receiver + form of be + past participle + by + doer, as in The team was praised by the coach.
- The subject in active voice does the action, while the subject in passive voice receives the action.
- Common forms of be include am, is, are, was, were, be, being, and been.
- A past participle is often the verb form used in passive voice, such as written, chosen, built, seen, or completed.
- To change passive voice to active voice, move the doer into the subject position and use a clear action verb.
- Use active voice when you want writing to sound clear, direct, and energetic.
- Use passive voice when the doer is unknown, unimportant, or less important than the action or result.

Common Mistakes to Avoid
- Calling every sentence with is or was passive is wrong because some be verbs describe a state, as in The door is red.
- Forgetting to identify the doer is a mistake because active voice depends on knowing who or what performs the action.
- Leaving a passive sentence wordy is a problem because phrases like was completed by can often become a stronger active verb.
- Changing the meaning while revising is wrong because active and passive versions should keep the same basic action and participants.
- Using passive voice in every formal sentence is a mistake because formal writing can still be clear, direct, and active.
Practice Questions

- 2 Identify whether each of these 3 sentences is active or passive: The dog chased the ball. The ball was chased by the dog. The homework was collected.
- 3 Write 2 original sentences about school, one in active voice and one in passive voice.
- 4 Explain why a writer might choose passive voice in the sentence The rare painting was stolen last night.
Understanding Active vs Passive Voice
A reliable way to spot voice is to find the main verb first, then ask what receives its action. Only verbs that can act on something can usually form a passive sentence. The verb kicked can act on a ball, so it can become passive.
The ball was kicked. In contrast, arrived does not act on an object. A sentence such as Maya arrived late has no receiver to move forward, so it cannot become passive in the usual way.
This is why some sentences cannot be revised from passive to active. Start by identifying the complete verb phrase, not just one word near the verb.
Passive voice can hide the person or group responsible for an action. Compare Mistakes were made with The lab team made mistakes. The first sentence leaves out important information.
In school writing, this can make a claim sound vague or avoid responsibility. Students often use passive voice by accident when they write about their own work. The experiment was completed does not tell the reader who completed it.
If the writer matters, name the person, group, or source. We completed the experiment gives a clearer record of what happened. This matters in lab reports, history assignments, news writing, and explanations of procedures.
Passive voice is not automatically weak. It helps when the result deserves the reader's attention. In a science report, The sample was heated to sixty degrees keeps the focus on the sample and the procedure.
The person using the equipment may not matter. In history, The city was destroyed in the fire centers the people and place affected. A writer may not know the doer, as in The window was broken overnight.
Passive voice can create a formal or objective tone, but too much of it can make a paragraph feel distant. Good choices depend on the purpose and the information the reader needs first.
When revising, do more than swap word positions. Find the real doer, place it early in the sentence, and choose a precise verb. The decision was made by the principal can become The principal approved the new schedule.
The revised sentence is shorter because it removes extra verb words and uses a stronger verb. Watch for sentences with forms of be that are not passive. In The leaves are green, are links leaves to a description.
No action is being received. In The leaves are falling, are falling shows an ongoing action, not passive voice.
Reading sentences aloud helps reveal long, crowded phrases. Check whether each sentence clearly shows who did what, unless you have a reason to keep that information in the background.
