When writing a paper, it is very important to cite references, because it can support your point of view, provide evidence and strengthen your argument. However, too many or incorrect references may lead to high repetition rate. Here are some suggestions to help you cite references reasonably and avoid high repetition rate:

1. Know the citation rules: First of all, you need to know the citation rules of your school or periodical. Different academic institutions may have different citation format requirements, such as APA and MLA. Make sure you are familiar with and abide by these rules to avoid unnecessary repetition.

2. Select the appropriate citation method: Select the appropriate citation method according to the citation rules you use. In some cases, you can use indirect quotation or abstract to quote references instead of copying the original text directly. This can reduce the repetition rate and still convey the main points of the original text.

3. Quote original materials: Try to quote original materials instead of second-hand materials. Original materials are usually more reliable and authoritative, and can provide more information and evidence. If you must quote second-hand information, you must clearly mark the source and explain and analyze it in the article.

4. Cite multiple sources: Try to avoid quoting only one source. By quoting multiple sources, you can show your comprehensive understanding of the topic and provide more evidence to support your point of view. At the same time, it can also avoid over-reliance on a specific source, thus reducing the repetition rate.

5. Cite appropriate scope: When quoting references, make sure to quote only the content related to the topic of the paper. Don't quote too much or irrelevant information, which will increase the repetition rate and reduce the quality of the paper.

6. Use citation management tools: Using citation management tools can help you better manage and organize your references. These tools can help you automatically generate a list of citations and references, and ensure that your citations are in the correct format.

In a word, citing references reasonably is the key to avoid high repetition rate. By understanding the citation rules, choosing appropriate citation methods, citing original materials, citing multiple sources, and using citation management tools, the problem of high repetition rate can be effectively avoided and the quality of papers can be improved.
