Active and Passive Voice

Definition Of Voice:

Voice is the form of the verb which indicates whether a person or a thing does something or something has been done to a person or a thing.

Voice is that form of a Verb which shows whether what is denoted by the Subject does something or has something done to it.

Explanation:
Verb can be divided into two ways. that is

(a) HELPING VERB: (is, am, are, was, were, been, being, shall be, will be)
(b) PRINCIPAL VERB: (eat, drink, see, play, go, run, ring, write. bark etc.)
(a) TRANSITIVE VERB: In transitive verb, action passes from the Subject (Doer) to the object. In other words, a transitive verb requires an object.
For example:- (i) You fly a kite. (ii) They play cricket. (iii) The cat killed a rat.
(b) INTRANSITIVE VERB: An intransitive verb does not require an object.
For example:- (i) I go to school. (ii) The dog barks. (iii)The sun shines.

A transitive verb requires an object: therefore, it has two voices. These are 'ACTIVE VOICE' and 'PASSIVE VOICE'

But Intransitive Verb has no object: therefore, it has only one voice i.e. Active Voice.

Type Of Voice

1- Active Voice:

When a verb form shows that the subject (person or thing) has done something, or, in other words, is the doer of the action. it is known as Active Voice. The Active Voice is so called because the person denoted by the Subject acts.
e.g.: I eat a mango

2- Passive Voice:

When a verb form shows that something has been done to the subject (person or thing) It is known as Passive Voice. The Passive Voice is so called because the person or thing denoted by the Subject is not active but passive, that is, suffers or receives some action.
e.g: A mango is eaten by me.

Examples:

S.No.	Active Voice	Passive Voice
1.	Roma helps Harry.	Harry is helped by Roma.
2.	Sam loves them.	They are loved by Sam.
3.	The mason is building the wall.	The wall is being built by the mason.
4.	The peon opened the gate.	The gate was opened by the peon.
5.	Some boys were helping the wounded man.	The wounded man was being helped by some boys.
6.	He will finish the work in a fortnight.	The work will be finished by him in a fortnight.
7.	Who did this ?	By whom was this done?
8.	Why did your brother write such a letter ?	Why was such a letter written by your brother ?

RULES FOR CHANGING ACTIVE INTO PASSIVE VOICE

A sentence can be separated into subject. verb and object.
e.g.: Nabeel(S) writes(V) a letter(O).
The object of the active voice must be turned into subject of the passive voice.
e.g.: A letter(S) is written(V) by Nabeel(O).
The 'be' form (is, am, are, was, were, be, being, been, etc.) must be used according to the tense of the verb and according to person and number of the noun in the subject position.
e.g.: A letter 'is'
Past participle of the verb must be used. (Principal verb will be change to its 3^rd form)
e.g.: A letter is written. ( write changes to written)
Preposition 'by' must be added.
e.g.: A letter is written by
The subject of the active voice becomes the object of the passive voice.
e.g.: A letter is written by Nabeel.

Subject in Active Voive Object in Passive Voice
Name of person or thing e.g Nabeel Name of person or thing e.g Nabeel
I by me
We by us
You by you
He by him
She by her
They by them
A transitive verb is sometimes followed by numbers of objects In such cases, the sentence may have two positive forms. e.g.:
Active Voice: The principal granted him the permission.
Passive Voice: The permission was granted to him by the principal.
Passive Voice: He was granted the permission by the principal.
Certain verbs are always followed by prepositions. So a preposition after the verb must be retained in Passive Voice. e.g.:
Active Voice: He laughed at her.
Passive Voice: She was laughed at by him.
Some ideas like commands/orders/requests may be expressed in Passive voice. e.g:
1. Please post these letters. (Active)
You are requested to post these letters. (Passive)

2. Close the door. (Active)
You are ordered to close the door. (Passive)
Imperative sentences: (Sentences which have no subject and are expressed in order form):
Imperative sentences are of two type:
(i) "Do it" (Affirmative) and
(ii)(Don't do it" (Negative)
They can be turned into Passive Voice by using 'let'.
Formula: Let +Object + Be + Verb (Past Participle)
e.g.:
1. Post this letter. (Active)
Let the letter be posted. (Passive)

2. Close the door. (Active)
Let the door be closed. (Passive)

3. Help the poor. (Active)
Let the poor be helped. (Passive)

4. Don't do it again (Active)
Let it not be done again. (Passive)
Passive with Modal Auxiliaries: Modal auxiliaries or simple modals are 'will, would, shall, should, can, could, may, might, must, have to, has to, had to, ought to, had better etc.
Pattern: Modals + be + Verb (past participle)
Example:
Active Voice: She can type the letters.
Passive Voice: The letters can be typed by her.

Active Voice: They should not do it.
Passive Voice: It should not be done by them.
We can omit the agent (the subject of the active voice) in the passive voice if it is a pronoun or it is unimportant)

Subject in Active Voive	Object in Passive Voice
Name of person or thing e.g Nabeel	Name of person or thing e.g Nabeel
I	by me
We	by us
You	by you
He	by him
She	by her

(b)Passive Sentences With Two Objectives

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.
When there are two objects after a verb, the first object is usually an indirect object or a pronoun and the second object is a direct object or a noun.
The subject of passive voice is often the indirect object.

Example:

Active Voice: He made her fool.
Passive Voice: She was made fool by him.
Active Voice: He gave me a present.
Passive Voice: I was given a present by him.

	Subject	Verb	Object 1	Object 2
Active	Raja	wrote	a letter	to me
Passive	A letter	was written	to me	by Raja
Passive	I	was written	a letter	by Raja

(c) Passive without subject

We use passive voice when:
(i) We don't know the agent.
(ii) We don't want to mention the agent.
(If a passive sentence does not indicate the subject, someone or somebody may be added to it or whatever is best suited.)

Pattern: to be (form) + V (past participle)

Someone sings a song. (Active)

Someone wrote letters (Active)
