The meaning expressed in green font is easy to understand. It means there is no duplication or overlap, but some parts cited in it have little influence. Therefore, there are many green fonts in the duplicate checking report, indicating that the repetition rate of the paper is in a relatively low position, while red and crimson indicate that the repetition of font content is very serious, and the overlapping ratio of red represents more than 50%.
Black means there is no repetition. If most of your test reports are black and green, then you are qualified.
Take the report of the duplicate checking system of HowNet as an example. Words marked in black in the report are not repeated, words marked in red are plagiarism, and words marked in green are quotations. If the repetition rate of words is high, it is necessary to change and adjust the repeated words, that is, the words marked with red and green, in order to reduce repetition. Generally speaking, words marked in black do not need to be modified. If it is suspected that black words are duplicated, it can also be modified to ensure that the total repetition rate can be effectively reduced.
First of all, you can be sure that the red part must be changed, because this is included in your check ratio. You can use some agreed synonyms instead, or divide long and short sentences, and reverse the word order without affecting the meaning of the whole sentence.
Because you marked the green part, it means that you quoted other people's literature or papers, and these green parts are allowed to appear in the graduation thesis. Try to say it in your own understanding, that is to say, you can quote it, but the proportion in the full text should not be too high.
