Narrations are a genre of literature that convey emotions and thoughts by describing a person or an event. If you don't have any exams, you might feel a little uneasy because you don't have any chance to show off your talent. But you can try to write a story about an interesting event from your childhood or a sport you liked. You can start with an interesting experience when you were young, describing how you started the sport, your love and pursuit for it, and how you overcame difficulties and challenges. You can show your creativity and imagination in the story, and you can also describe your emotional experience. In the process of writing, you can try to use some rhetorical devices such as metaphor, personification, contrast, etc. to enhance the performance of your story. You can relate your story to the characters and environment around you so that readers can better understand your story. No matter what you write, you must maintain your sincerity and frankness, as well as your enthusiasm and interest in the story. Believe in yourself, believe in your work, and let the readers feel your emotions and thoughts.
