The yellow part represents the quotation part, the red part is the plagiarism part, the red part needs to be completely revised, and the yellow part needs to be marked with references for reference. The quoted parts are usually marked in red, because the author quoted fragments or even sentences from the article. According to the duplicate checking rule of HowNet, as long as a line is more than 13 words, it is judged to be duplicate. Therefore, the author of the paper should try to avoid over-quoting. The modification of the quoted part can try to understand the original intention of the quoted part and express it in its own way. For some famous aphorisms, we can increase the number of words in the article through explanation, thus increasing the basic part of the article, so as to dilute the repetition of this part.
