1, delete useless sentences
After getting the duplicate check report, there will inevitably be many sentences marked in red. Delete those sentences that you think are useless. After deleting these redundant sentences, the overall content and structure of the paper will not be affected. But the premise of a large number of deletions is that your paper has enough words.
Step 2 replace synonyms
Substitute words with similar meanings, such as "research on ..."
Step 3 change the word order
If the repetition rate of the whole paragraph is high, you can read through this paragraph and understand it, disrupt the original structure, re-integrate the language, and add words with similar meanings between the original words.
