The document discusses active and passive voice in English grammar. It provides examples of sentences written in active voice versus passive voice, and explains how to change an active sentence to passive voice. The key aspects are: - Active voice has the subject performing the action, while passive voice has the subject receiving the action. - To change to passive voice, move the active sentence's object to be the subject, place the original subject in a "by" phrase, and use a form of "be" plus the past participle of the main verb.

7. Active voice
In most English sentences with an action verb, the subject performs the action denoted
by the verb.
These examples show that the subject is doing the verb's action.
Because the subject does or "acts upon" the verb in such sentences, the sentences are said to be in
the active voice.

8. Passive voice
One can change the normal word order of many active sentences (those with a direct
object) so that the subject is no longer active, but is, instead, being acted upon by the
verb - or passive.
Note in these examples how the subject-verb relationship has changed.
Because the subject is being "acted upon" (or is passive), such sentences are said to
be in the passive voice.
NOTE: Colorful parrots live in the rainforests cannot be changed to passive voice
because the sentence does not have a direct object.

9. To change a sentence from active to
passive voice, do the following:
1. Move the active sentence's direct object into the sentence's
subject slot

10. 2. Place the active sentence's subject into a phrase beginning with
the prepositional phrase by

11. 3. Add a form of the auxiliary verb be to the main verb and change
the main verb's form

12. 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.

13. 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.

14. subject verb object
active Everybody drinks water.
passive Water is drunk by everybody.
The object of the active verb becomes the subject of the passive verb:

15. 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).

16. 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.

17. 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

18. 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 It will have
been washed.
conditional It would have
been washed.
perfect continuous present It has been
being washed.
past It had been
being washed.
future It will have been
being washed.
conditional It would have been
being washed.
