First of all, we need to clarify the function and significance of the original sentence. Originality statement refers to the author's explicit statement of the originality and independence of his works in his paper. This is the author's commitment to the authenticity and innovation of his research work.

However, in the current paper-based duplicate checking system, whether it is necessary to copy the original report is a controversial issue. Some people think that the original statement is the author's promise and should not be verified by the duplicate checking system. They believe that the original statement is an academic moral constraint and the author should consciously abide by it. On the other hand, some people think that the duplicate checking system should check the authenticity of the original statement to ensure the originality and academic integrity of the paper.

However, the current duplicate checking system can not effectively detect the authenticity of the original report. The duplicate checking system mainly judges the similarity by comparing the text of the paper with the quoted content, but it can't directly detect the authenticity of the original sentence. Therefore, whether to copy the original statement needs further discussion and exploration.

From a practical point of view, checking the original sentence may increase the complexity and cost of the checking system, and at the same time it will add extra burden to the author. However, if the original statements are not checked, some authors may intentionally provide false original statements, thus undermining the purpose of repeated checking. Therefore, it is necessary to weigh various factors and comprehensively consider whether to check the original statement.
