The duplicate checking rate of general undergraduate thesis is about 20%, which is subject to the requirements of the school. If the school requires a repetition rate of 20% and students' papers 19%, it is better to continue to revise the red part of the papers. Because the update time of HowNet database is very fast, the data will change after repeated inspection every once in a while, so it is suggested that the duplicate checking rate should not be too close to the requirements of the school, and it should be revised as far as possible if it is close.

Extended data

If the repetition rate of the paper is lower than the standard required by the school, it does not need to be revised. However, if the repetition rate of the paper is close to or higher than the standard required by the school, then the part marked in red in the paper needs to be revised, otherwise it will be considered plagiarism. When revising a paper, if there are sentences used by others in the paper, the sentence structure can be changed and the order between sentences can be disrupted, which can reduce the duplicate checking rate; For the explanatory text, you can rebuild it in your own words.
