Passives | EXPLANATION AND EXERCISES
Passives are used whenever an action is more
important than the agent – for example, in reporting the news or
scientific experiments;
• A woman has been arrested for the
abduction of baby Emily Smith.
The object of the active verb
becomes the subject of the passive sentence, and the verb be is used
in the correct tense with the past
participle of the relevant verb.
By + the agent is used only if it
contributes important information:
• Coastal buildings have been damaged by
gales.
Intransitive verbs, e.g. arrive, cannot become
passive, because they have no object.
Certain other verbs, e.g. let, fit,
lack, resemble, suit, cannot normally become passive.
After modal
verbs, passive infinitives are used :
• He ought to be arrested. • You might have
been killed.
Passive -ing forms are possible:
• She likes being driven to work. • Having
been fed, the dog went to sleep.
Many verbs, like give, award, lend,
can have two objects. When putting these verbs into the passive, it is more
usual to make the 'person object', rather than the 'thing object', the subject
of the passive verb:
• I was given back my change. (NOT My
change was given back to me).
Passive constructions are often used with
verbs like say, believe, and know.
It + passive + that-clause:
• It is said that three people died in the
accident.
• It was once believed that the earth was
completely flat.
Subject + passive + to + infinitive:
• Three people are said to have died in the
accident.
• The earth was once believed to be
completely flat
Sometimes there are two passive
constructions in the same sentence:
• It is known that York was invaded by the
Vikings.
• York is known to have been invaded by the
Vikings.
Other verbs which are used in this way
include:
consider,
think, understand, report, allege, expect, fear, claim and
deny. The verb be rumoured only exists in the passive form.
If phrasal verbs or verbs with prepositions become part of a passive sentence, they
must not lose their particle:
• The child was extremely well looked
after.
