PASSIVE Voice in English

Collected & compiled by Hamid R. Bagheri

Functions and examples

We use the passive when who or what causes the action is not important or is not known, or when we want to focus on the action.

1. The rubbish is taken out every day.

(We don't know who takes the rubbish out, or maybe it's not important)

2. The Great Wall of China was built thousands of years ago.

(It's not important exactly who built it, we want to focus on the action of building)

3. The money has been stolen.

(We don't know who stole it, and we want to emphasize the action of stealing)

4. My windows are cleaned once a month.

(It's not important who cleans them. The action of cleaning is more important)

Important points

If there are two objects in the active sentence, two passive sentences are possible.

Active: They gave me 50 dollars to do it.

Passive: I was given 50 dollars to do it / 50 dollars was given to me to do it.

Get is often used instead of be in informal spoken English.

I got offered the promotion.

The table got damaged in the fire.

I got asked to present the award.

The subject of the active verb (sometimes called the agent) is not usually expressed in passive sentences, because it is unknown or unimportant. However, if it is used, it is usually preceded with 'by'.

The painting was done by Picasso.

When we talk about a tool used by an agent, it can be preceded by 'with'.

The painting was done with oils on canvas.
