Rules of passive voice
The active voice is the common word order.

We put the subject (somebody or something that performs the action) in the first place. Then, we put the verb. And then goes the object (something or someone that receives the action of the verb).

The passive voice conveys the action that is performed on the person or object that is the subject in the sentence. It is often used when we do not care or do not know who is performing the action. To form the passive voice, the verb "to be" in the appropriate form and the past participle of the semantic verb (the third form) are used.

• If it is necessary to specify the performer of the action (an animated noun or pronoun), use the preposition "by": The book was written by A. Miln.
• If you need to specify what the action is performed with, then use the preposition "with": The experiment was made with water and coal.

There are two voices in the English language: active and passive.

In the active voice there's the [ ] word order.

We put the subject (somebody or something that performs the action) in the first place. Then, we put the verb. And then goes the [ ] (something or someone that receives the action of the verb).

For example: [ ].

Here the word "I" is the subject, and "window" is the object.

In the passive voice, something or somebody that receives the action becomes the [ ] of the sentence. Now it goes to the first place. And the "doer" of the action is placed in the prepositional phrase or left out.

For example: [ ].

In this sentence, the word "window" is the subject and "[ ]" is the prepositional phrase.

We use the passive:

• when the object is more important than the subject;
• when the "doer" of the action is unknown, not important or obvious;
• in formal or scientific writing.
