First of all, academic papers usually include title, abstract, keywords, introduction, literature review, research methods, results, discussion, conclusions and references. These parts have their specific purposes and functions, such as the title and abstract are used to summarize the main contents of the paper, the introduction is used to introduce the background and purpose of the research, the literature review is used to evaluate and summarize the existing research, the research methods are used to describe the design and methods of the research, the results and discussions are used to show and explain the results of the research, the conclusion is used to summarize the main findings of the research, and the references are used to list the cited documents. This structured writing style is helpful for readers to understand and evaluate the content and quality of the paper.

In contrast, the structure of ordinary articles is usually more flexible and free. It may include title, beginning, body and ending, but the content and order of these parts can be adjusted according to the author's needs and creativity. For example, a news report may first introduce the background of the incident, then describe the process of the incident in detail, and finally discuss the impact of the incident; An essay may first describe a scene, then unfold the story through memory or imagination, and finally end with feeling or thinking. This unstructured writing style is more conducive to expressing the author's personal perspective and feelings.

Generally speaking, the main difference between academic papers and ordinary articles in structure lies in rigor and depth. Academic papers need to follow a certain structure and format to ensure the accuracy and reliability of their contents; Ordinary articles can give full play to the creativity and imagination of the author more freely.
