This is a vivid and literary composition topic. "Light" is not a literal "real reference", but a virtual reference behind the literal meaning. What is the object of "virtual finger"? In fact, it has been revealed in the materials, such as "lighting a lamp of love in your own heart not only illuminates the night of other people's spiritual homes, but also brings achievements and pleasure to your own life station", which is the meaning direction of the proposition. Therefore, you only need to understand that the topic itself is a metaphor, "lamp" is a metaphor, and "some spiritual characteristics of human mind" is an ontology, such as sincerity, tolerance, care, humility, introspection and other beautiful human nature, and then interpret or describe some spiritual characteristics that people need in their hearts, thus pointing out its significance. As for the choice of style, it varies from person to person. Good at narrative and description, you can write a narrative and tell a story about the lamp of the soul, so that the emotions are shocking; If you are good at argumentation, you can write an argumentative essay, dialectically analyze the harm caused by the lack of a beautiful lamp of human nature (such as the lamp of care) in your mind, and tell people that we should remove the stones from your mind, clear the obstacles in your mind and light the lamp of your heart, so that our road to life will be wider and wider.
