The position marked red must be changed, and the green part should not be moved as much as possible, because it has passed the examination. As for the orange part, you can modify it according to your actual situation. The suggestion is to modify it as much as possible when time permits, at least don't let the orange part turn red, so that the duplicate checking rate can really fall to the requirements of the school.
The meaning of colored parts
Green part:
If there are many green parts in the paper, then your paper is still reliable, and the duplicate checking rate is generally not high. Green is the original part, that is, the system does not check that your sentences are similar, and this part does not need to be modified.
Red part:
The red part is a serious repetition. Generally, if the paper is repetitive and the color turns red, it means that the similarity of your paper has reached more than 80%. This is also the reason why many people mark a paragraph in red, because the current duplicate checking system belongs to intelligent fuzzy duplicate checking, that is to say, if more than 80% of your paper is similar to other documents, it is also a serious duplication.
Orange part:
For example, some reports have orange parts, and the similarity of this part is generally within 50%, but not more than 50%, which is suspected of duplication. If you don't want the duplicate checking rate to be too high, this part must also be revised.
