To win honor for the class is to think more about the class as a collective and not do anything that will damage the honor of the class. Establish the consciousness of "being proud of my class and being ashamed of my class". Actively participate in the activities organized by the class and participate in various activities on behalf of the class.

I am also a junior high school student, and my writing is not very good. I only said a rough idea. You have to think about the rest yourself and write more fully.
