1. Xu Zhang's task is to explain his topic selection, the main direction of the paper, the process and situation of literature retrieval (that is, what the predecessors have done in this regard), what innovations (or arrangements) the paper has, the research methods used, the general structure of the paper and other issues that need to be explained.
Second, the introduction of the writing requirements
1, the preface should come straight to the point and get to the point quickly. Argumentative writing usually requires straight to the point, so that readers can get in touch with the center of the article from the beginning and understand what the basic content of the article is, instead of "digressing Wan Li", which leads readers around the center of the article and makes them confused.
2. Foreword should be attractive and catch the reader. From the beginning, let readers have a good initial impression on the article and have an interest in reading. This requires the preface to have substantive content and easy to attract readers.
3. The preface should be concise and powerful. Don't be too long at the beginning, so as not to appear top-heavy and asymmetrical. A complicated and lengthy beginning will make readers have a bad impression and can't bear to read it. At the beginning, it should be like setting off firecrackers, which suddenly rings and makes people tremble. The text at the beginning of graduation thesis should be concise and powerful.
