What's Active Voice?
When the subject of a sentence performs the verb’s action, we say that the sentence is in the active voice. Sentences in the active voice have a strong, direct, and clear tone. It follows a clear subject + verb + object construct that's easy to read.
Examples:
She buys milk
I ran to the hill yesterday
What's Passive Voice?
A sentence is in the passive voice, on the other hand, when the subject is acted on by the verb. The passive voice is always constructed with a conjugated form of to be plus the verb’s past participle. Doing this usually generates a preposition as well. That sounds much more complicated than it is—passive voice is actually quite easy to detect.
Example:
Active Voice : She buys milk
Passive Voice : Milk is bought by her
Remember, not every active voice can be changed into passive voice.
Only Active voice with Transitive verb, not Intransitive verb.
Transitive Verb
Verb that needs object.
like: buy, eat, drink, make
Example:
_I_ _buy_ _meat_
S V O
Intransitive Verb
Verb that doesn’t need object.
like: go, come, sleep, run
Example :
_I_ _go to_ _school_
S V Adv

Why using active voice?
Using the active voice conveys a strong, clear tone. The sentences with active voice are shorter and more direct.
Why using passive voice?
The subject ( the one doing the acts ) is not that important, and when we want to focus attention on the person or thing affected by the action.
