With the continuous development of university education, writing graduation thesis has become one of the inevitable tasks for students. In the process of thesis writing, duplicate checking has always been a topic of great concern. However, some students and researchers have raised a question: Does the abstract need to be copied?

First of all, the abstract of the paper is a short and pithy article, generally no more than 500 words. This paper mainly introduces the theme, purpose, research methods, achievements and conclusions of the paper, which is an important part of the paper writing. Therefore, the abstract of the paper reflects the quality and content of the whole paper to a certain extent and needs to be checked again. Otherwise, once the abstract is plagiarized, it will not only affect the evaluation of the paper, but also bring unnecessary trouble to the author.

Secondly, the abstract of undergraduate thesis is different from that of graduate thesis. The abstract of graduation thesis contains more detailed information, so it is more demanding. The abstract of undergraduate graduation thesis mainly emphasizes the importance and achievements of the research, hoping to attract readers' attention. Therefore, the degree of duplicate checking of undergraduate thesis abstracts will be relatively low, but attention should also be paid to avoiding plagiarism.

Finally, it should be clear that the abstract of the paper is not the whole paper, so duplicate checking is not an appropriate method to measure whether there is plagiarism in the whole paper. Although proofreading is needed, more attention should be paid to the proofreading of the whole paper to ensure the quality and independence of the paper.

To sum up, although the abstract of the paper is short, it needs to be proofread again to prevent the negative effects caused by plagiarism. At the same time, we should also pay attention to the duplicate checking of the whole paper to ensure the quality and independence of the paper.
