First of all, we need to understand the purpose and principle of losing weight. As a common academic practice, weight reduction aims to prevent plagiarism and ensure the legitimacy of academic research. The process of reducing weight is usually carried out through a weight inspection system. The duplicate checking system will compare the paper with various documents, find out the similar parts, and give the author tips and guidance to modify the paper. Therefore, in the process of losing weight, literature citation is an important aspect.

So, when quoting the literature, do you need to change it? According to the research and comprehensive analysis of this paper, we come to a conclusion: in general, there is no need to change the cited documents.

First of all, the documents cited in a paper are usually some published and recognized excellent documents. These documents are not only objective, authoritative and reliable, but also widely circulated and used in academic fields. Therefore, the contents of these files should not be changed at will.

Secondly, in the process of losing weight, citing literature itself is not the key point. The focus is on the part of the paper that has been revised to avoid plagiarism. Therefore, when you lose weight, you only need to modify the content that is highly similar to other materials, not the literature itself.

Finally, in some special cases, it is really necessary to make appropriate modifications to the referenced documents. For example, the wrong, outdated or inaccurate contents in the literature need to be revised to ensure the correctness and credibility of the paper.

In short, it is not customary to change the cited documents during weight loss. However, in some specific cases, it is necessary to make appropriate revisions to the literature. These revisions should be based on an accurate understanding and rational analysis of the contents of the literature and avoid arbitrary changes. I believe that through the elaboration of this paper, we can better understand and master the related issues of the paper and provide help for writing high-quality academic papers.
