Repetition rate: this is one of the most commonly used duplicate checking criteria, which is mainly measured by comparing the similarity between papers and existing documents. Generally speaking, the repetition rate of English papers is required to be within 20%, and the specific standards may vary from school to school and from periodical to periodical.
Citations and references: Correct citation and reference formats are very important for judging the repetition rate of English papers. When quoting other people's research results, you must indicate the source and provide a complete list of references at the end of the article. In addition, it is necessary to pay attention to whether the quoted content is included in the repetition rate and whether the quoted format conforms to academic norms.
Originality: English papers must be original, and others' achievements should not be excessively copied or quoted. At the same time, the author should express the research contents and achievements in his own language, and avoid directly copying and pasting or simply modifying the existing contents.
Language expression: The language expression of English papers must be accurate, clear and concise, and conform to academic norms and grammatical rules. If the language expression is inaccurate or irregular, it may affect the quality of the paper and the results of duplicate checking.
Format and typesetting: the format and typesetting of English papers should meet the requirements of schools or periodicals, including font, font size, line spacing, margins and so on. The standardization of format and typesetting is also an important criterion to measure the quality of English papers.
