Create an atmosphere: If the same sentence appears many times in the article, the reader will feel that this sentence can create an atmosphere for the entire article, allowing the reader to better feel the emotions and atmosphere of the article. Intensified tone: If the same sentence appears many times in the article, the reader will feel that this sentence has strengthened the tone of the article, allowing the reader to better feel the author's tone and emotions.
