1. Active Voice
Active voice is used to express the subject of the verb which is performing the action or causing the happening described by the verb. With active voice. we learn who or what is the one responsible of the action immediately because the actor is express at the beginning of the sentence. Active voice create more powerful sentences than passive voice.
Use of active voice:
1. Active voice is used in a clause whose subject expresses the agent of the main verb.
2. Subject can be easily identified by asking ‘who’ or ‘what’ to the verb.
3. Sentences are short and easily understandable.
Example :
John wrote the letter.
- John (subject) performs the action denoted by the verb (write).
2. Passive Voice
If someone use passive voice, it means they want to focus more on the object. Passive voice focuses on who or what is receiving the action and not on who or what is performing the action. The actors, in passive voice, are told at the end of the sentences or maybe even unknown.
Use of passive voice:
1. It is used if we don‘t need to know or don‘t know the actor performing the job.
2. We use passive voice if we want to know more about the job than the actors.
Example:
My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not know who did it. Sometimes a statement in passive is more polite than active voice.
A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone. Sometimes passive voice also used to express “not in purpose” things.
Recognizing Passive Voice
You can recognize passive voice easily because passive voice will always have "to be" in the clauses or sentences. on the other hand,the presences of "to be" doesn't always mean that the clauses or sentences are passive voice. Another way to recognize passive voice is that they may have "by the" after the verbs when they try to tell us the actors performing the actions.

Transitive and Intransitive Verbs
Transitive verbs are verbs which have subjects and object in one sentences or clauses. Transitive verbs can be in active or passive voice. Transitive verbs in active voice are the verbs which are followed by the direct objects. A transitive verbs needs object to express full meaning.
Example: The boy kicked the ball. The subject is the actor who does the action and the direct object is the receiver of the action.
Meanwhile, Transitive passive verbs have the subject receiving the action.
Examples: The ball was kicked by the boy. The ball was kicked hard. The verbs in the transitive passive voice always have "is, am, are, was, were, be, being, or been" as auxiliaries.
Intransitive verbs don't have receiver of the action. They are classified as intransitive complete or intransitive linking. Intransitive linking are sentences with a predicate nominative or predicate adjective.
Examples: The girl is Mary. (predicate nominative) The girl is cute. (predicate adjective) Intransitive complete are all the verbs that don't fit one of the other kinds of transitive or intransitive verbs.
Examples: The bell rang suddenly. The girl knitted all evening. (There is no receiver of the action.) They were here. (no action or predicate nominative or predicate adjective).
Intransitive verb cannot be changed into passive voice. The sentences which have intransitive verbs cannot be changed into passive voice. The reason behind that statement is that there is no object in the sentences and we all know that without objects we cannot change the sentences to passive voice.
List of common intransitive verbs:

arrive become
belong collapse
cost depend
die emerge
exist fly
go happen
laugh occur
