Passive Voice
v 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.).
v 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:
ñthe object of the active sentence becomes the
subject of the passive sentence
ñthe finite form of the verb is changed (to
be + past participle)
ñthe subject of the active sentence becomes the
object of the passive sentence (or is dropped)

v 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.

Active:

Rita

|
Passive:

|
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.
v
Personal and Impersonal Passive
Personal Passive simply
means that the object of the active sentence becomes the subject of the passive
sentence. So every verb that needs an object (transitive verb) can form a
personal passive.
Example: They build houses. – Houses are built.
Verbs without an object (intransitive verb) normally cannot
form a personal passive sentence (as there is no object that can become the
subject of the passive sentence). If you want to use an intransitive verb in
passive voice, you need an impersonal construction – therefore this passive
is called Impersonal Passive.
Example: he says – it is said
Impersonal Passive is
not as common in English as in some other languages (e.g. German, Latin). In
English, Impersonal Passive is only
possible with verbs of perception (e. g. say, think, know).
Example: They say that women live longer than men. – It
is said that women live longer than men.
Although Impersonal Passive is
possible here, Personal Passive is more
common.
Example: They say that women live longer than men. –
Women are said to live longer than men.
The subject of the subordinate clause (women) goes to the
beginning of the sentence; the verb of perception is put into passive voice.
The rest of the sentence is added using an infinitive construction with 'to'
(certain auxiliary verbs and that are
dropped).
Sometimes the term Personal Passive is
used in English lessons if the indirect object of an active sentence is to
become the subject of the passive sentence.
