Sentences which cannot be changed into passive voice
Sentences which cannot be changed into passive voice
Transitive and intransitive verb
A verb can be either transitive or intransitive. A transitive verb needs an object (in sentence) to give complete meaning while intransitive verb does need an object (in sentence) to give complete meaning.
For example,
Transitive verb.
He sent a letter.
(Send is a transitive verb and it needs an object i.e. letter to express full meaning.)
Intransitive Verb.
He laughs.
(Laugh is an intransitive verb and it does not need object for expressing full meaning.)
e.g. Sleep, go, reach, sit, die, are examples of intransitive verbs.
Intransitive verb cannot be changed into passive voice
The sentences having intransitive verbs (belonging to any tense) cannot be changed into passive voice. The reason is that there is not any object in such sentences and without object of sentence passive voice is not possible.
A sentence can be changed into passive voice if it has subject and object. Sometimes subject may not be written in passive voice but it does not mean that it has no subject. Such sentences have subject but the subject is so common or familiar or known that if even it is not written in passive voice, it gives full meaning.
For example
Cloth is sold in yards.
The following tenses can also not be changed into passive voice.
Present perfect continuous tense
Past perfect continuous tense
Future continuous tense

Active and Passive Voice
Active and Passive Voice
There are two ways to express an action of a subject in relation to its object
• Active voice
• Passive voice
In “active voice” subject acts upon object, while in “passive voice” object is acted upon by subject. It can also be said, in “active voice” subject does a work on object, while in “passive voice” object is worked on by subject. The normal structure of an active voice sentence is subject+verb+object but in passive the normal structure of sentence is reversed according to certain rules and becomes like object+verb+subject. The real meaning of a sentence does not change if the sentence is expressed either by active voice or by passive voice. The active voice is mostly used in writing because it gives a direct and more concise meaning. Passive voice is used sometimes due to the following reasons.
When intentionally hiding the subject of sentence. For example, a student who failed in exam might say, some chapters were not studied.
Another example. Women were not treated as equals
When passive voice better explain thought of sentence. For example, to say, cloth is sold in yards, is more meaningful than to say, Shop keepers sell cloth in yards.
When passive voice better emphasizes the main though of the sentence. For example, a man who is being teased by another person might say in anger, “you will be beaten by me”
When subject is not exactly known. For example, His watch was stolen. It is not known that who stole his watch, the subject (thief) is not exactly known so it is better to use passive voice for such sentence.There are certain rules for expressing a thought in passive voice or for changing a sentence from active voice to passive voice.
Fundamental Rules for changing from active voice to passive voice
The places of subject and object are interchanged i.e. the object shifts to the place of subject and subject shifts to the place of object in passive voice. Example.
Active voice: I write a letter.
Passive voice: I letter is written by me.
Subject (I) of sentence shifted to the place of object (letter) and object (letter) shifted to the place of subject (I) in passive voice.
Sometimes subject of sentence is not used in passive voice. Subject of sentence can be omitted in passive voice, if without subject it can give enough meaning in passive voice.Examples.
Passive voice: cloth is sold in yards
3rd form of verb (past participle) is always used as main verb in sentences of passive voice for all tenses. Base form of verb or present participle will be never used in passive voice.
The word “by” is used before subject in sentences in passive voice.Example.
Active voice: He sings a song.
Passive voice: A song is sung by him.
The word “by” is not always used before subject in passive voice. Sometimes words “with, to, etc” may also be used before subject in passive voice.
Examples.
Active voice: The water fills the tub.
Passive voice: The tub is filled with water.
Active voice: He knows me.
Passive voice: I am known to him.
