First of all, it is very important to understand the principle and rules of duplicate checking system. Different duplicate checking systems may use different comparison algorithms and judgment criteria, so understanding the working principle of the system can help us to make better modifications. At the same time, we also need to know which parts of the text are compared by the duplicate checking system, such as the quoted part and our own original content.

Secondly, make a detailed self-examination of the paper. After finding that the duplicate checking rate is too high, it is necessary to carefully check whether there are duplicates or similarities with other people's works in the paper. In particular, citations and references should be marked accurately and standardized, and personal understanding and innovation should be added to citations. Find and combine the language repetition and vocabulary repetition in the theoretical text, and express your argument in more precise terms.

Then, modify the structure and content of the paper. In the case of high duplicate checking rate, we can try to readjust the structure and content of the paper, add more original content and research viewpoints, and reduce the similarity with other people's works. We can deepen the argument of this paper and add more empirical analysis and data support. In addition, you can try to add more critical thinking and innovative ideas to highlight your academic independence and originality.

Finally, after the above modification and adjustment, the duplicate checking system is used again for detection. If the duplicate checking rate is still too high, you can continue to modify the above steps repeatedly until the requirements are met. In addition, we can consult tutors or other professionals for review and revision, and their opinions and suggestions can help us better improve the quality and originality of the paper.
