Passive voice

Active VS Passive Voice

In active voice, the receiver of the action is the object in a sentence.

He delivers the letters.
 Subject     Verb           Object      

In passive voice, the object of the active sentence becomes the subject.We use the passive voice when we want to emphasize the object than the subject.

The letters are delivered by him.
           Subject                Verb                                 

And when we don't know who or what the subject is, or it is obvious.

The letters are delivered.

 Subject           Verb        

Both have the same meaning. The receiver of the action has a different position, but it is still who receives the action.

.

The passive is formed:

Verb be + Past Participle

We can use it any tense:

Personally speaking, I think that the use of active voice is clearer than the passive, but the passive voice is necessary to add variety to your writing. We can use it in the case that the performer of the action is unknown or irrelevant, and when the process is the most important thing in the text.
