However, as non-native English writers, even if we think that our English level is good, it is often just about exam-oriented, grammar ability, or simple oral communication, so we often need SCI polish.

SCI papers to master's and doctoral students, scientific researchers, and college teachers is self-evident. However, as non-native English writers, even if we think that our English level is good, it is often just about exam-oriented, grammar ability, or simple oral communication, so we often need SCI polish. But why is the price of polishing SCI English papers so expensive?

　The biggest difference between non-native English writers and native speakers is fundamentally different from those in English and Chinese. Secondly, for written English, it is sometimes difficult for us to understand long and difficult sentences, let alone write richly hierarchical sentences. Furthermore, the limited vocabulary and the limitations of Chinese and English expression conversion make our English writing less authentic and hinder the reading of native speakers. Therefore, the SCI we write often needs SCI polishing.

　　Figure 1. Differences between Chinese and English logic and expression conversion

　　Based on this, most of the polishing needs to be completed by native English speakers. SCIs that do not have language quality are often rejected as soon as they arrive at the editor. Academic English is very different from ordinary and more colloquial English. If you do not understand the standards for writing academic papers, do not have corresponding background knowledge, and do not understand the logic of the research content of the paper, even native English speakers cannot polish the paper. This is like if you let Chinese people who do not study medicine read Chinese works, they are also confused. This is why they need to convert academic papers into popular science articles for the public to understand. Because of this, most journals also require authors to polish before submission, and have accelerated the manuscript processing process.

　　To sum up, polishing SCI papers not only requires English skills, but also professional paper writing skills, and also requires understanding of the academic progress and experimental methods of the article. It is not difficult to understand why the polishing price of SCI English papers is so expensive.

　　Of course, the polishing costs are also different for different polishing requirements. If you only modify the wrong spelling, grammar and other issues based on the original text, take ELSEVIER as an example. The 7 working days are higher than US$165 per thousand words (equivalent to about RMB 1,177), and the 1 to 4 working days are higher than US$280 per thousand words (equivalent to about RMB 1,997); Edels (https://www.editsprings.cn/?utm_term=20221008&utm_source=zhihu) is only RMB 300 per thousand words, which is much more affordable than ELSEVIER. If the language of the article is further modified based on the wrong spelling, grammar and other issues, the article is further modified to ensure the smoothness of the article, clearly expressing it when reading, and even modifying the logic of the article, take ELSEVIER as an example. The 5 working days are higher than US$326 per thousand words (equivalent to about RMB 2,325), while the Ades Company is only RMB 1,260 per thousand words. At the same time, when polishing foreign polishing companies, they can often only contact each other by email, and the communication efficiency is not high; while domestic companies can often contact the docking specialist in time to understand the editing status of the manuscript.

　　So, if the number of words in an SCI paper is 5,000 words, the English polishing cost is at least about 6,000 yuan, and if logical modification is made, it is at least about 12,000 yuan. In comparison, domestic polishing companies only cost 1,500 yuan, up to 6,300 yuan. Therefore, on the premise that the polisher is reliable and can ensure polishing treatment, choosing a domestic polishing company can save a lot of money and communicate smoother.
