Active voice and passive voice are common when you start to learning english. Sometimes, active voices sounds easier to learn than passive voice. But for me, i think learning both is fun and easy because i learn it in my own way.

In the video, i explain that active voice is follow a clear subject + verb + object. But for passive voice, there's a formula for it.

Object + "To be" + Past Participle + By + Subject

Also in the video, i give some example to make you understand how to change active voice into passive voice. Enjoy the video, folks.
