Warning in advance: this will be a long answer. (including common expressions of papers and Japanese literature retrieval methods) The subject asked, "Can you write a Japanese paper as authentic as writing a Chinese paper in a short time?" Then I want to understand this question as: "Can you write a Japanese paper with authentic Japanese expression in a short time?" Because I personally think that "the expression of mother tongue level" is only a sufficient condition for writing an authentic paper, not a necessary and sufficient condition. To write an "authentic paper", it is not enough to express it only at the mother tongue level. In addition to language factors, fresh and refined views, rigorous and self-consistent logical thinking structure (my Japanese professor said that as a foreigner, language expression doesn't have to be so authentic, but he attaches great importance to the internal logic built between the lines of the article! ! ), a solid professional knowledge reserve and other factors are essential. To put it simply, not everyone can write an "authentic paper" even if the native speaker is English. Then "can you write a Japanese paper with authentic Japanese expression in a short time?" Generally speaking, I think that as long as I work hard, I can approach "a Japanese paper with authentic Japanese expression" infinitely in 2-3 months given by the topic owner. First of all, we can break down the structure of the article and then talk about it one by one. If you look at the most urgent needs of the project, write a research plan first. (I have written this many times and changed it many times! ! Personally, I think the research proposal is actually a bit like the first half of a formal paper.
