Why do we need a passive voice?

1.  The passive voice is used to show interest in the person or object that experiences an action rather than the person or object that performs the action. In other words, the most important thing or person becomes the subject of the sentence.
2. The use of passive voice in academic writing is mostly because it is more objective, more rigorous, and more convincing;

Instances：

• “Mistakes were made.”
• “The window got broken.”
• “Have you ever been kicked by an elephant?”
• “Don’t get killed.”
• “Being attacked by Geoffrey Howe was like being savaged by a dead sheep.”
