Features of comments:

1, the explanation should be based on the characteristics of the explanation object, with clear themes and key points, and should not be comprehensive. It should highlight the main aspects of things, grasp the key points of things, and even expand the content, it should not be divorced from the theme of the explanation. If the object of text explanation is the universe, then it should be introduced in close connection with the composition of the universe, and other problems should not be brought up at will.

2. Commentary supplements the narrator's relevant information, mainly the expansion of knowledge and reason, so that readers can accept the meaning that pictures and objects themselves cannot convey and express. For example, the introduction of the basic concept of light-year (knowledge expansion) in this paper compares the universe to the sea and stimulates readers' imagination of the universe (rational expansion).
