Use of Passive
Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.)
Form of Passive
Subject + finite form of to be + Past Participle (3rd column of irregular verbs)
Example: A letter was written.
When rewriting active sentences in passive voice, note the following:
- the object of the active sentence becomes the subject of the passive sentence
- the finite form of the verb is changed (to be + past participle)
- the subject of the active sentence becomes the object of the passive sentence (or is dropped)
Examples of Passive
| Tense | Subject | Verb | Object | |
|---|---|---|---|---|
| Simple Present | Active: | Rita | writes | a letter. |
| Passive: | A letter | is written | by Rita. | |
| Simple Past | Active: | Rita | wrote | a letter. |
| Passive: | A letter | was written | by Rita. | |
| Present Perfect | Active: | Rita | has written | a letter. |
| Passive: | A letter | has been written | by Rita. | |
| Future | Active: | Rita | will write | a letter. |
| Passive: | A letter | will be written | by Rita. | |
| Modal verbs | Active: | Rita | can write | a letter. |
| Passive: | A letter | can be written | by Rita. | |
Examples of Passives
| Tense | Subject | Verb | Object | |
|---|---|---|---|---|
| Present Progressive | Active: | Rita | is writing | a letter. |
| Passive: | A letter | is being written | by Rita. | |
| Past Progressive | Active: | Rita | was writing | a letter. |
| Passive: | A letter | was being written | by Rita. | |
| Past Perfect | Active: | Rita | had written | a letter. |
| Passive: | A letter | had been written | by Rita. | |
| Future II | Active: | Rita | will have written | a letter. |
| Passive: | A letter | will have been written | by Rita. | |
| Conditional I | Active: | Rita | would write | a letter. |
| Passive: | A letter | would be written | by Rita. | |
| Conditional II | Active: | Rita | would have written | a letter. |
| Passive: | A letter | would have been written | by Rita. | |
Passive Sentences with Two Objects
Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on.
| Subject | Verb | Object 1 | Object 2 | |
|---|---|---|---|---|
| Active: | Rita | wrote | a letter | to me. |
| Passive: | A letter | was written | to me | by Rita. |
| Passive: | I | was written | a letter | by Rita. |
As you can see in the examples, adding by Rita does not sound very elegant. That’s why it is usually dropped.
The passive with reporting verbs
The passive is also used to describe feelings, beliefs and convictions. It isn't always necessary to include the agent. Some of the most common verbs used are believe, consider, expect, hope, know, say, suppose, think and understand. We can form these passive structures in two ways.
(a) subject + passive reporting verb + to + infinitive
This hospital is considered to be the best in the country.
She is thought to be living in India.
(b) It + passive reporting verb + that + subject + verb
It is said that scientists are working in a new cure for the disease.
It is hoped that the new drug will work.
