The main body of the paper includes five parts: preface, literature review, research design, results and analysis, and conclusion.

Introduction and conclusion are the two most important parts. Introduction is the first part of the paper. This part of the writing generally needs to explain the background, significance and purpose of the topic, and can briefly introduce the basic viewpoints and conclusions of the article. The introduction part should not be too long, get straight to the point, get into the topic quickly, and attract readers to read the article through concise words.

The conclusion is the last part of the text and the final conclusion of the whole text. It is a conclusion drawn through the rigorous proof and inference mentioned above, so this part is also a summary. It is not appropriate to put forward new ideas, and the language expression should be concise and powerful.

A complete and excellent graduation thesis must have the following routine parts: preface, literature review, research design, results and analysis, and conclusion. On this basis, we can make personalized supplements according to the needs of the paper. Writing a good thesis is actually telling a good story, telling a well-founded and self-evident story. Each chapter has information that needs to be explained to readers, and each chapter is closely linked. Each chapter has not only the evidence of the previous station, but also the foreshadowing of the next chapter, which embodies the author's argument logic.
