Material preparation: a computer and WPS software.

1. Open the article to which you want to add a document, and select the paragraph to which you want to add a document.

2. Click the "Reference" option above.

3. Click "Insert endnote" and write the source at the bottom of the paper. If you want to change the style of the footnote, click the small arrow next to the footnote to change it.

4. The documents cited in the paper should be numbered in square brackets in the upper right corner of the narrative text of the author or literature achievement according to the order in which they appear in the text, or as part of the sentence.

The function of marking the source of the paper;

1. The significance of citing sources in academic papers is not only to avoid plagiarism, but also to explain the current research situation.

2. It is a necessary courtesy for readers to indicate the source of quotation, which can help readers to consult the quoted original text, especially the online resources.

3. Citation will increase the credibility of the paper.

4. Even published papers should pay attention to citation. Many student authors lack the awareness of paper copyright, so it is easy to ignore these problems.

Matters needing attention in writing a paper:

1, the objectivity of the article content.

Articles must be objective and true, not based on personal subjective feelings, because everyone's feelings are different, so we must write papers from an objective perspective. We should pay attention to the overall tone of the article, so when writing, we should try our best to explain it in an objective tone instead of using the first person frequently. We can use words such as "according to statistics" and "according to relevant research" to express it.

2. The logic of the paper is reasonable.

The logic of the paper means that the architecture design, writing order, arguments and context should be reasonable and compliant. The thesis must correspond to the theme, and don't put forward arguments in the previous articles, but in the later articles, it is found that the content and arguments are inconsistent. This will confuse the title and text of the article and greatly reduce the quality of the content of the paper.

3. The hierarchical structure of the paper.

The hierarchy of the paper refers to the orderly content, reasonable paragraph layout and scientific overall structure.
