In general we tend to use the active voice. That is when a subject does an action to an object.
The passive voice is used when we want to emphasize the action (the verb) and the object of a sentence rather than subject. This means that the subject is either less important than the action itself or that we don’t know who or what the subject is.
When we know who the subject is, we put it at the end with by. We call this an agent.
Most writing instructors and editors recommend against using the passive voice, when possible. The reason for this is that when you use the active voice, your writing is clearer and less complicated.
If it’s a long sentence and you know who the subject is, it’s best to use the active voice.
The passive is often used to report something or to state a fact.
The passive voice is not a tense in English. Each tense has its own passive voice which is created by using a form of the auxiliary verb to be + V3 (past participle)
The passive voice in each tense:
|Tense||Auxiliary verb + sample V3 (past participle)||Examples|

|Present progressive||am, is, are + being + sent||

All of the rules for passive negatives and questions are the same as for the active voice.
Note: Verbs that have no object (no one to “receive” the action) cannot be put into the passive, such as, arrive, come, die, exist, go, happen, have, live, occur sleep, etc.
