The Passive Voice

The passive changes the camera angle of a sentence: it makes the affected person or thing the subject. Learn to build it across tenses and decide when it improves the message.

A clear route through the lesson

Make the affected person or thing the subject when that is the useful focus. Add the agent only when the reader needs it. The compact extra forms below prepare you for the full quiz.

Read the explanations, answer aloud at each You say pause, then reveal the model and check one point. A model is one possible answer. Finish with the 10-question understanding check.

Keep the learner’s speaking time. At each You say pause, use the suggested follow-up and one correction focus. Finish with the 10-question understanding check.

The essential rules

Form: be + past participle

Keep the tense in be; the main verb becomes a past participle. The object of the active sentence becomes the subject.

They deliver parcels. → Parcels are delivered.

Choose the focus

Use passive voice when the doer is unknown, obvious, unimportant, or less important than the action or result.

My bike was stolen. · The results will be announced Friday.

Add the agent only if useful

Use by when the agent is new, surprising or important. Do not automatically include it.

The novel was written by Toni Morrison. · The road was repaired.

Two useful forms to add

Continuous passive: They were preparing dinner → Dinner was being prepared. Use am/is/are being now, and was/were being in the past.

Passive reporting: People say the bridge is safe → It is said that the bridge is safe, or The bridge is said to be safe. These report a claim; they do not prove it.

Choose the focus: “The volunteers repaired the hall” highlights who did the work. “The hall was repaired by volunteers” keeps the hall as the topic. Neither is automatically better.

See the pattern

Tense/formActivePassive
Present simpleThey clean the rooms.The rooms are cleaned.
Past simpleThey built the bridge.The bridge was built.
Present perfectThey have sent the email.The email has been sent.
ModalThey must finish it.It must be finished.
Teacher tip: Find the tense first. Build the same tense with be, then add the past participle. This prevents most passive errors.

Three mistakes to avoid

✕ The room cleaned every day.
✓ The room is cleaned every day.
The passive needs a form of be.
✕ The bridge was build in 1990.
✓ The bridge was built in 1990.
Use the past participle.
✕ The report has sent.
✓ The report has been sent.
Present perfect passive is has/have been + participle.

Guided practice

Try each item before opening the answer.

1. Change to passive: People speak English in many countries.

English is spoken in many countries.

2. Change to passive: Someone stole my phone last night.

My phone was stolen last night. The unknown agent is omitted.

3. Change to passive: They will publish the results tomorrow.

The results will be published tomorrow.

4. Is passive better? “Shakespeare wrote Hamlet.”

Usually keep the active because the famous agent is important. Passive is possible if Hamlet is already the topic.
