Avoiding accidental plagiarism is an important issue that must be paid attention to when writing a paper. Here are some suggestions to help you avoid accidental plagiarism:

1. Understand the difference between citation and plagiarism: citation is the rational use of other people's opinions, research results or words, while plagiarism is the complete copying of other people's works without authorization. Understanding these differences will help you abide by the principle of academic integrity.

2. Carefully plan the quotation: When using the quotation in the paper, please make sure to clearly indicate the source and provide complete quotation information after the quotation. You can use reference management software or manually create a reference list to ensure that all references are handled correctly.

3. Do a good job in literature review: When conducting literature review, don't directly copy and paste other people's words and opinions. Instead, you should summarize and explain the work of others and relate it to your research topic.

4. Describe and explain in your own language: When introducing other people's research results or opinions, try to describe and explain in your own language. Even if you need to quote the original text, try to express it in your own words instead of simply copying and pasting.

5. Check your own work: Before submitting your paper, be sure to check your article carefully to ensure that there is no accidental plagiarism. You can use plagiarism detection tools to help you find potential problems. However, please note that these tools are not perfect, and it is best for professionals to conduct the final audit.

In short, it is very important to abide by the principle of academic integrity and avoid accidental plagiarism for maintaining academic reputation and promoting knowledge exchange. Accidental plagiarism can be effectively avoided by understanding the difference between citation and plagiarism, carefully planning citation, doing a good job of literature review, describing and explaining in your own language, and checking your own works.
