As writers, we must always stay vigilant about keeping our readers engaged. If the audience becomes bored of our writing, we run the risk of losing them all together. Whether we write fiction or non-fiction, the best way we can do this is by maintaining the use of active voice in our sentences. In order to do this, we must firmly understand the difference between the active voice and the passive voice. By identifying the subject of each sentence, we can determine whether it uses the active voice or the passive voice.
