In novels, BE was the contraction of be up(also known as be on), which was usually used to describe the actions or states of a character at a certain moment. In novels, Be was usually used to express the emotional changes in the character's heart, the development of the story, and the switching of scenes. For example, a character might suddenly wake up to find himself in an unfamiliar environment or at a critical moment, find himself faced with a choice. The description of these scenes would usually show the complexity and contradictions of the characters 'hearts through being, so that the readers could better understand the characters' psychology and actions.
