Tenses and the passive
We use passive forms of tenses in the same way as we use their active equivalents. For example, we use the present simple in the passive to talk about general or permanent states, or general facts we think are true at the present time:
Mr Lloyd and Mrs James teach Geography. (present simple active)
Geography is taught by Mr Lloyd and Mrs James. (present simple passive)
We don’t often use perfect continuous forms (have/has been being + -ed form) in a passive structure. We usually find a way to reword sentences like this.
| not common, we usually avoid this form |
| preferred form |

Verbs and the passive
We can form passive structures with verbs that are followed by an object (transitive verbs) and some clauses where the verb is followed by a preposition:
My favourite mug was broken. (Someone broke my favourite mug.)
Their car was broken into and the radio was taken. (Someone broke into their car and took their radio.)
The holiday hasn’t been paid for yet. (No one has paid for the holiday yet.)
We can’t make passive forms from verbs which do not have objects (intransitive verbs):
The parcel arrived in the post this morning.
Not: The parcel was arrived …
We don’t usually use the passive with some verbs that describe a state or situation (state verbs):
They were having lunch.
Not: Lunch was being had.
Some verbs are more common in the passive than the active voice. These include be born, be populated, be stranded, be taken aback:
Where were you born?
Thousands of passengers have been stranded at airports all over Europe after heavy snowfalls.
Verbs with two objects
When verbs have two objects, either object can be the theme or subject of the passive structure, depending on what we want to focus on:
Her mother gave each child a present. (active)
A present was given to each child (by her mother). (passive)
Each child was given a present (by her mother). (passive)
Linking verbs
We don’t form passive structures with verbs like be, become, seem where the complement of the verb refers back to the subject (linking verbs):
After six years of training she has finally become a doctor.
