1. First, add and replace words and phrases in repeated sentences. For example, if you quote a passage from others, you can add a little, but the core words cannot be changed, which will greatly reduce the repetition rate.

2. Second, adjust. Adjustment means adjusting sentences and order. If the active sentence and passive sentence are interchanged and the meaning of the sentence remains the same, we can find ways to adjust and change the sentence.

Third, modifiers, such as "to undergraduates", can be changed to "to undergraduates", and everyone modifies words in different ways. In this case, the duplicate checking rate of papers will be greatly reduced.

4. How to reduce the weight of papers? The core words cannot be changed, and there is no way to change the core words, that is, try to change irrelevant words. When the core word is changed, the original meaning of the sentence changes. Therefore, try to correct irrelevant words in your own language. In short, the weight loss of the paper is through "adding, adjusting and changing words". Please refer to official website of Xue Ke Bank for duplicate check of the paper.
