First of all, read the relevant literature extensively, understand the previous research results and viewpoints, and avoid repeating published results. By expanding the reading range, we can better grasp the hot spots and trends in the current research field and conduct targeted research.

Secondly, pay attention to innovative thinking and carry out independent research work. When doing research, we should pay attention to thinking and analysis to find new problems and solutions. Through independent research, we can improve the originality of the paper and reduce the duplication of research with others.

In addition, reasonably quote other people's achievements and avoid plagiarism. In the process of writing, we should reasonably quote other people's research results and correctly mark the citation sources. At the same time, we should also pay attention to our understanding and summary of the quoted content to show our research ability.

In addition, the duplicate checking system has played an important role in reducing the duplicate checking rate of papers. The duplicate checking system can help us to detect duplicates in papers and provide similarity reports. By using the duplicate checking system, the problems in the paper can be found in time and revised and improved in time, thus reducing the duplicate checking rate.

To sum up, the methods to reduce the duplicate checking rate of English papers are: reading relevant documents extensively, paying attention to innovative thinking, quoting others' achievements reasonably, and using duplicate checking system. These methods can help us improve the originality and independence of the paper and ensure the realization of academic integrity. In the future research work, we should pay attention to the cultivation and promotion of these aspects to better meet the academic requirements.
