A sentence generally begins with the performer of the action (subject), then the verb, then the object or person that the action is performed on. This is called an "active sentence".
E.g
Subject + verb + object : Marry send the letter
If we begin the sentence with an object. It is called a "passive voice".
E.g
Object + verb + subject : the letter is sent by Marry
Based on youtube video Anglo-link, we can use passive sentence :
1. When we do not know who subject is
or It is not importat who subject is.
E.g : somebody clean the room.
Become the room was cleaned.
2. It is obvious to the reader or listener because somebody usually does it.
E.g : the cleaner clean the room become room was cleaned.
The characteristic of active and passive voice :
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 participial phrase.
[Having been] designed for off-road performance, the Pathseeker does not always behave well on paved highways.
ACTIVE- is best known when the subject comes first in a sentence followed by an action.
This sentence type is generally shorter.Verb use is generally active. (often accompanied by are or is "Be" verbsEven if being done in the past tense, the verb generally follows the subject. In essence, make the person doing the action come first.
PASSIVE: The Passive sentence structure generally moves the direct object of the ACTIVE sentence to the beginning of the sentence, putting the person (doing) the action in a secondary role - We do use this method in trans-social grammar but only in formal writing where we are only reporting and from an emotional distance from the topic.
So yes, there is a place for passive voice.
Passive sentences are usually longer, demanding more tense "being" verbs in order to function.Passive sentences tell us that what is being done is more important than who is doing it. The reason you aren't supposed to write "passive" sentences is because this condition flies in the face of the "universe rule" -- the person is always the most important (socially).The Passive voice often leads off with the CLEFT subjectThe SUBJUNCTIVE (tag) sentence is the closest to passive and we tend to use it to make peace or to get something we want.

Formulate the passive voice :
1. Put the object in the beginning of the sentence.
2. Conjugate the verb to be with the same active form tenses.
3. Put the main verb in the past participle form.
Note :
No one or nobody in the passive voice can be negative :
E.g no one turn on the light become the lighg was not turned on.
If there is preposition in the active voice it will remain after verb in passive voice.
E.g we talk about love become love was talked about.
The passive voice in different tenses :
Present tense
I do it (active) : it is done (passive)
Past simple
I ate the bread (active) : the bread was eaten by me (passive)
Present continous
I'm doing it (active) : it is being done (passive)
Past continous
I was doing it (active) : it was being done
Present perfect
I have done it (active) : it has been done
Past perfect
I had done it (active) : it had been done (passive)
Modal auxiliaries :
I can do it (active) : it can be done (passive)
Conclusion :
Based on the explaination above the writer draw several conclusion about this material.
Definition of active and passive voice.
An active voice is used when the subject does an action. While, the passive voice is used when the object put in the beginning of the sentence.
Formulate the passive voice
The teacher teaches Biology is an active voice sentence if we want to change into passive sentence. First, we have to know the object. In this active sentence the object is 'Biology' and the verb 'teaches' and the subject 'the teacher'. Usually the object are in the end of the sentence, like this active sentence example. So, we put 'Biology' as the object into the first position of the sentence become Biology...... and then the verb to be 'am' and change the verb into past participle 'taught' and finally the subject the teacher. Become Biology is taught by the teacher. And, remember to change the tenses with the active voice sentence. The different/formulation have explained above this written.
