Active Voice, Passive Voice

Construction of the Passive Voice

There are two special forms for verbs called voice:

The structure of the passive voice is very simple:

1. Active voice
2. Passive voice

subject + auxiliary verb (be) + main verb (past participle)

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 ver
b
Cats

eat

object
>
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.

The main verb is always in its past participle form.


Look at these examples:
subject
Water
100
people
I
We
Are

auxiliary verb (to


be)
is
are
am
are
they

main verb (past


participle)
drunk
employed

by everyone.
by this
company.
in euro.
in dollars.
in yen?

paid
not paid
paid

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
give importance
President Kenned
to active object
y
(President
Kennedy)
active subject
My wallet
unknown

verb
was killed

object
by Lee Harvey Oswald.

has been stolen


.

Note that we always use by to introduce the passive object (Fish are eaten by
cats).
1

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".

Active or Passive Quiz

I ate a piece of chocolate cake.

The librarian read the book to the students.

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:

The money was stolen.

They are paid on Fridays.

The movie is being made in Hollywood.

present simple: It is made

I washed my car three weeks ago.

present continuous: It is being made

His hair was cut by a professional.

I will introduce you to my boss this week.

It would have been fixed on the weekend.

Active / Passive Verb Forms


Sentences can be active or passive. Therefore, tenses also have "active
forms" and "passive forms." You must learn to recognize the difference to
successfully speak English.
Active Form
In active sentences, the thing doing the action is the subject of the sentence and the
thing receiving the action is the object. Most sentences are active.
[Thing doing action] + [verb] + [thing receiving action]

___________________________________ in the plan?


11. They had finished the preparations by the time the guests arrived.

Examples:

The preparations ________________________________by the time the


guests arrived.
12. You should take care when working on electrical equipment.
Care _________________________________when working on electrical
equipment.
13. They are going to perform Beethoven's Fifth Symphony next weekend.
Beethoven's Fifth Symphony
____________________________________________ next weekend.
14. Someone will speak Japanese at the meeting.
Japanese_________________________ at the meeting.

Passive Form
In passive sentences, the thing receiving the action is the subject of the sentence
and the thing doing the action is optionally included near the end of the sentence.
You can use the passive form if you think that the thing receiving the action is more
important or should be emphasized. You can also use the passive form if you do not
