We should do our homework before writing the introduction. For example, we investigate the situation from reading literature, grasp the latest trends, and the purpose of the study. Therefore, papers generally need references, that is, citations, otherwise there is no basis, and tutors with a repetition rate of 0% will also let you revise them. You can't lose extra points.
Matters needing attention in writing introduction
1, multi-purpose scientific language
When reflecting the current research level, we should use less newspaper-style current affairs language that looks "concise" and use more scientific language. Scientific language is symbols, formulas, concepts, definitions, laws, theorems, tables, curves, photos and so on.
2. Reasonable selection of references
Reference should be more authoritative literature, classic literature, recent literature, cited literature, less teaching materials, less random or unintentional or unfiltered literature. Use less and don't use "second-hand literature", but use the most useful literature in research, which you often refer to and can't be put down at hand. "Second-hand literature" refers to "reference" literature that you have not copied or read, but have seen from literary works.
3. Collect information at any time
Is to be a thoughtful "willing heart" at any time. Write down valuable information as soon as you meet it. Even if you have finished your research, don't forget to consult the latest literature in the library before writing the draft paper. Before writing chapter 1, we should start to collect and supplement the literature again.
4. Literature review
One of the fundamental tasks of literature review is to find out the most valuable research work and direction. In the literature review, we should introduce the preliminary work of our discipline group. With these, the work of the research group can be inherited and developed.
