Passive  And Active Voices

Kata kerja juga dikatakan baik aktif (Komite eksekutif menyetujui kebijakan baru) atau pasif (Kebijakan baru ini disetujui oleh komite eksekutif) dalam suara. Dalam suara aktif, hubungan subyek dan kata kerja sangat mudah, subjek adalah be-er atau do er dan kata kerja bergerak sepanjang kalimat.             
 CONTOH KALIMAT PASSIVE VOICES :
Verbs are also said to be either active (The executive committee approved the new policy) or passive (The new policy was approved by the executive committee) in voice.
In the active voice, the subject and verb relationship is straightforward: the subject is a be-er or a do-er and the verb moves the sentence along. In the passive voice, the subject of the sentence is neither a do-er or a be-er, but is acted upon by some other agent or by something unnamed (The new policy was approved).
Computerized grammar checkers can pick out a passive voice construction from miles away and ask you to revise it to a more active construction. There is nothing inherently wrong with the passive voice, but if you can say the same thing in the active mode, do so (see exceptions below). Your text will have more pizzazz as a result, since passive verb constructions tend to lie about in their pajamas and avoid actual work.
We find an overabundance of the passive voice in sentences created by self-protective business interests, magniloquent educators, and bombastic military writers (who must get weary of this accusation), who use the passive voice to avoid responsibility for actions taken. Thus "Cigarette ads were designed to appeal especially to children" places the burden on the ads — as opposed to "We designed the cigarette ads to appeal especially to children," in which "we" accepts responsibility.
At a White House press briefing we might hear that "The President was advised that certain members of Congress were being audited" rather than "The Head of the Internal Revenue service advised the President that her agency was auditing certain members of Congress" because the passive construction avoids responsibility for advising and for auditing. One further caution about the passive voice: we should not mix active and passive constructions in the same sentence: "The executive committee approved the new policy, and the calendar for next year's meetings was revised" should be recast as "The executive committee approved the new policy and revised the calendar for next year's meeting."
Take the quiz (below) as an exercise in recognizing and changing passive verbs. The passive voice does exist for a reason, however, and its presence is not always to be despised. The passive is particularly useful (even recommended) in two situations:
  • When it is more important to draw our attention to the person or thing acted upon: The unidentified victim was apparently struck during the early morning hours.
  • When the actor in the situation is not important: The aurora borealis can be observed in the early morning hours.
The passive voice is especially helpful (and even regarded as mandatory) in scientific or technical writing or lab reports, where the actor is not really important but the process or principle being described is of ultimate importance. Instead of writing "I poured 20 cc of acid into the beaker," we would write "Twenty cc of acid is/was poured into the beaker." The passive voice is also useful when describing, say, a mechanical process in which the details of process are much more important than anyone's taking responsibility for the action: "The first coat of primer paint is applied immediately after the acid rinse."
We use the passive voice to good effect in a paragraph in which we wish to shift emphasis from what was the object in a first sentence to what becomes the subject in subsequent sentences.
The executive committee approved an entirely new policy for dealing with academic suspension and withdrawal. The policy had been written by a subcommittee on student behavior. If students withdraw from course work before suspension can take effect, the policy states, a mark of "IW" .
The paragraph is clearly about this new policy so it is appropriate that policy move from being the object in the first sentence to being the subject of the second sentence. 
The passive voice allows for this transition.

Passive Verb Formation
The passive forms of a verb are created by combining a form of the "to be verb" with the past participle of the main verb. Other helping verbs are also sometimes present: "The measure could have been killed in committee." The passive can be used, also, in various tenses. Let's take a look at the passive forms of "design."

Tense
Subject
Auxiliary
Past
Participle
Singular
Plural
Present
The car/cars
is
are
designed.
Present perfect
The car/cars
has been
have been
designed.
Past
The car/cars
was
were
designed.
Past perfect
The car/cars
had been
had been
designed.
Future
The car/cars
will be
will be
designed.
Future perfect
The car/cars
will have been
will have been
designed.
Present progressive
The car/cars
is being
are being
designed.
Past progressive
The car/cars
was being
were being
designed.





A sentence cast in the passive voice will not always include an agent of the action. For instance if a gorilla crushes a tin can, we could say "The tin can was crushed by the gorilla." But a perfectly good sentence would leave out the gorilla: "The tin can was crushed." Also, when an active sentence with an indirect object is recast in the passive, the indirect object can take on the role of subject in the passive sentence:

Active
Professor Villa gave Jorge an A.
Passive
An A was given to Jorge by Professor Villa.
Passive
Jorge was given an A.


Only transitive verbs (those that take objects) can be transformed into passive constructions. Furthermore, active sentences containing certain verbs cannot be transformed into passive structures. To have is the most important of these verbs. We can say "He has a new car," but we cannot say "A new car is had by him." We can say "Josefina lacked finesse," but we cannot say "Finesse was lacked." Here is a brief list of such verbs*:
resemble
look like
equal
agree with
mean
contain
hold
comprise
lack
suit
fit
become
Verbals in Passive Structures

Verbals or verb forms can also take on features of the passive voice. An infinitive phrase in the passive voice, for instance, can perform various functions within a sentence (just like the active forms of the infinitive).
  • Subject: To be elected by my peers is a great honor.
  • Object: That child really likes to be read to by her mother.
  • Modifier: Grasso was the first woman to be elected governor in her own right.
The same is true of passive gerunds.
  • Subject: Being elected by my peers was a great thrill.
  • Object: I really don't like being lectured to by my boss.
  • Object of preposition: I am so tired of being lectured to by my boss.
With passive participles, part of the passive construction is often omitted, the result being a simple modifying Parcipial prase .

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
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.


Relationship between active and passive:  

1. The object of the active verb is the subject of the passive verb (“English” in the example sentences below). Therefore, verbs which cannot be followed by objects (intransitive verbs) cannot be used in passive voice.
These are some common intransitive verbs: appear, arrive, come, cry, die, go, happen, occur, rain, sleep, stay, walk. These verbs cannot be used in passive voice.

2. The passive verb always contains a form of the auxiliary verb be. The form of be in the passive verb phrase corresponds to the form of the main verb in the active verb phrase (see the underlined words in the example sentences below). That is, if the active main verb is simple present tense, then a simple present tense form of be is used in the passive verb phrase; if the active main verb is -ING, then the -ING form of be is used in the passive verb phrase; and so on.

3. The main verb in a passive predicate verb phrase is always the participle form of the verb.

4. Some examples of active and passive sentences:
ACTIVE: They speak English.
PASSIVE: English is spoken.
ACTIVE: They spoke English.
PASSIVE: English was spoken.
ACTIVE: They will speak English.
PASSIVE: English will be spoken.

5. Perfect progressive verb forms are generally used in active voice only. That is, these are good English sentences:
ACTIVE: They have been speaking English.
ACTIVE: They had been speaking English.
ACTIVE: They will have been speaking English.
But sentences like these are rarely used:
PASSIVE: English has been being spoken.
PASSIVE: English had been being spoken.
PASSIVE: English will have been being spoken.

Contoh kalimat beserta Rumus :
The formula of active voice is a common structure of a sentence; it should consist of subject, verb and object. If we want to change the structure into passive voice, we should change some of the elements in the sentence. The formula both of the voices are shown below:

Active voice
S + V + O + adjective/adverb
Examples of the sentences
1.       Rido  gives Lina a present in her birthday.
2.       They punched the thief yesterday.
3.       You wrote application letter for our company.
4.       Romi kicks the ball.

Passive voice
S + to be + VIII + by + O + Adjective/adverb
Examples of the sentences   
1.       The ball is kicked by Romi.
2.       Lina  is given a present in her birthday by Rido.
3.       The thief was punched by them yesterday.
4.       Application letter was written by me for your company.
In passive voice, there is also positive, negative and interrogative form of the sentence. The form is like the common formula. The example as follow:

Positive
Interrogative
1.       The boy is accompanied by his family.
1. Is the boy accompanied by his family?
2.        The tiger is killed by the hunter.
2. Is the tiger killed by the hunter?
3.       They are leaved by the teacher.
3. Are they leaved by the teacher?
4.       We are cheated by the officer.
4. Are the cheated by the officer?
5.       The garden is cleaned by Fani.
5. Is the garden cleaned by Fani?


Negative
Who – question
1.       The boy is not accompanied by his family.
1.Who is accompanied the boy?
2.        The tiger is not killed by the hunter.
2. Who is killed the tiger?
3.       They are not leaved by the teacher.
3. Who are leaved by the teacher?
4.       We are not cheated by the officer.
4. Who are the cheated to us?
5.       The garden is not cleaned by Fani.
5. Who is cleaned the garden?

Modal Auxiliaries in Passive Voice
                Modal auxiliaries consist of some modal such as: will, would, can, could, shall, should, thought to, must, may, and might. They are often used in the passive. The formula of this modal as follow :


Modal + be + past participle

Example of the sentence:
1.       She can be judged as the trouble maker.
2.       They should be transited in the guest room.
3.       We might be forgotten by them.
4.       The paper shall be leaved here by .
