ACTIVE AND PASSIVE VOICE
There are two special forms for verbs called voice:
Active voice
Passive voice
The active
voice is the
"normal" voice. This is the voice that we use most of the time. You
are probably already familiar with the active voice. In the active voice, the object receives the action of the verb:
active
|
subject
|
verb
|
object
|
|
>
|
||
Cats
|
eat
|
fish.
|
The passive
voice is less usual. In the
passive voice, the subject receives the action of the verb:
passive
|
subject
|
verb
|
object
|
<
|
|
||
Fish
|
are eaten
|
by cats.
|
The object of the active verb becomes the subject of the passive verb:
|
subject
|
verb
|
object
|
active
|
Everybody
|
drinks
|
water.
|
passive
|
Water
|
is drunk
|
by everybody.
|
Passive Voice
The passive voice is less usual than the
active voice. The active voice is the "normal" voice. But sometimes
we need the passive voice. In this lesson we look at how to construct the
passive voice, when to use it and how to conjugate it.
Construction of the Passive Voice
The structure of the passive voice is very simple:
subject + auxiliary verb (be) + main verb
(past participle)
The main verb is always in its past participle form.
Look at these examples:
subject
|
auxiliary verb (to be)
|
|
main verb (past participle)
|
|
Water
|
is
|
|
drunk
|
by everyone.
|
100 people
|
are
|
|
employed
|
by this company.
|
I
|
am
|
|
paid
|
in euro.
|
We
|
are
|
not
|
paid
|
in dollars.
|
Are
|
they
|
|
paid
|
in yen?
|
Use of the Passive Voice
We use the passive when:
we want to make the active object more important
we do not know the active subject
|
subject
|
verb
|
object
|
give importance to active object (President
Kennedy)
|
President Kennedy
|
was killed
|
by Lee Harvey Oswald.
|
active subject unknown
|
My wallet
|
has been stolen.
|
?
|
Note that we always use by to introduce the passive object (Fish are eaten by cats).
Look at this sentence:
He was killed with a gun.
Normally we use by to introduce the passive object. But
the gun is not the active subject. The gun did not kill him. He was killed by somebody with a gun. In the active voice, it would
be: Somebody killed him with a gun. The gun is the instrument.
Somebody is the "agent" or "doer".
Conjugation for the Passive Voice
We can form the passive in any tense. In
fact, conjugation of verbs in the passive tense is rather easy, as the main
verb is always in past participle form and the auxiliary verb is always be. To form the required tense,
we conjugate the auxiliary verb. So, for example:
present simple: It is made
present continuous: It is being made
present perfect: It has been made
Here are some examples with most of the
possible tenses:
infinitive
|
to be washed
|
|
simple
|
present
|
It is washed.
|
past
|
It was washed.
|
|
future
|
It will
be washed.
|
|
conditional
|
It would
be washed.
|
|
continuous
|
present
|
It is
being washed.
|
past
|
It was
being washed.
|
|
future
|
It will
be being washed.
|
|
conditional
|
It would
be being washed.
|
|
perfect simple
|
present
|
It has
been washed.
|
past
|
It had
been washed.
|
|
future
|

have been washed.
|
|
conditional
|

have been washed.
|
