The main expression of commentary is narration and explanation, and sometimes it is a combination of narration, explanation, description, lyricism and discussion. Excellent comments are often prose or prose poems that combine narrative with argument and lyricism.

How to write a good commentary?

1, we should grasp the main characteristics of the introduced object and pay attention to the use of typical and comparative methods to give people a real feeling. Highlighting typical examples, using contrast, combining point with surface, and revealing the essential characteristics of things from the outside to the inside are widely used in comments.

2. Be clear and simple. Explanations are mostly aimed at people who don't know something, so be sure to make it clear. What to say first, what to say later, and how to say it are easy to understand and should be considered comprehensively. Generally speaking, there are arrangements from total to division, from top to bottom, from bottom to top, from far to near, from shallow to deep, and from outside to inside. When explaining a thing in detail, you can follow the steps of object, conception, classification, comparison, analysis and summary. In other words, first explain what to introduce (concept, definition, category, affiliation, classification, inherent characteristics, etc.). ), and then explain what is needed and how to do it. Some have to be introduced according to the production process. In the commentary of documentary, due to the need of montage processing, it is allowed to jump with the "melting out" and "melting in" of the lens, but this jump is still internally related.

3. Have strong feelings and vivid language.

Commentary not only has the function of introduction and explanation, but also has certain appeal, which should arouse strong * * *. In order to express strong feelings, the commentary can use rhetorical devices such as parallelism, duality and repetition, and pay attention to the rhyme and rhythm of the language.
