Combined with the text, the role of sandstorm in the structure and conception of the article is to echo from beginning to end. It is an article with complete structure, deepening the central idea and defining the theme. The article begins with a prefix. The first is to let others read it, no matter whether an article is good or not. If people can't read it at first, they don't need to read it later. So a good start is like a person with a good face. Point at the beginning, guide the full text, point out the main idea, make people clear at a glance and attract readers. Draw out the following or set suspense for the following to attract readers and make readers have greater interest in reading. The end of the article is a summary of the full text, beginning and ending, just as people say that writing an article can't be anticlimactic. If the ending is not exciting enough to match the previous article, it can't be said to be a good article. Summarize the full text and ideas. Summarize the central idea of the full text and tell the central content of the article. It has aroused readers' thinking and benefited a lot. Echo the beginning, echo the end. It is an article with complete structure, deepening the central idea and defining the theme. Sublimate the theme and make people think.
