Now is the critical period for students to write their graduation thesis. Many students need to use some documents in their thesis writing, which involves a problem, how to use other people's documents, how to form good academic norms and avoid plagiarism. This is a very urgent problem now, but many of our classmates lack strict training and don't know when to copy and quote other people's articles. Here I want to make a simple discussion on this issue. This can only be regarded as a topic, and the purpose is to discuss this topic with you. What is plagiarism? Simply put, using other people's words or opinions without specifying them is plagiarism. If Fang thinks that "copying other people's words without indicating the source, using quotation marks to indicate others" constitutes plagiarism. The definition of plagiarism in the Author's Handbook of the American Modern Language Association is:' Plagiarism refers to using other people's opinions or expressions in your writing without properly indicating the source. ..... This includes repeating word for word, copying other people's works, or using opinions that don't belong to you without giving proper quotations. It can be seen that there are two kinds of plagiarism in papers: one is plagiarism, which uses other people's opinions without indicating them, making people mistakenly think they are their own; One is plagiarism, copying other people's written expressions, not indicating the source, using quotation marks, making people mistakenly think that it is your own expression. Of course, the former is more serious than the latter, because the paper pays attention to the originality of ideas. As for popular articles, it is different, because we don't pay attention to the originality of opinions, so we don't need to indicate the opinions from others one by one, only pay attention to whether the written expression is plagiarized. "(Fang's" Global "bimonthly issue 15, 2005, quoted from the Internet) So how to use other people's literature? Harvard University in the United States pointed out in its relevant student handbook, "If your sentence is very similar to the original data in terms of viewpoint and sentence structure, and the conclusion is similar to the quotation instead of repeating it in your own words, even if you indicate the source, it is plagiarism. You can't simply change a few words or summarize the original materials. You must completely reshape your summary with your own language and sentence structure, or quote directly. "Quoted from the relevant regulations of Harvard University, I saw the original text 1 years ago, and now I can't find the source. It can be seen that the use of other people's content must be completely rewritten, otherwise it is suspected of plagiarism. But here we should avoid patchwork and kneading. In short, we must respect other people's intellectual achievements and reflect what you have done and what others have done in the article. Of course, it is still difficult to do this now, but I think we should at least have this awareness, because in the concept of plagiarism, besides emphasizing that there is no indication, we also emphasize that it is not intentional. (Interview with Chinese and American professors on academic corruption, China Education and Research Computer Network,/20041122/3121356.shtml). Many of us make mistakes because we don't know what plagiarism is and how to avoid it, so it is very important to know what plagiarism is. In reality, it is difficult for our classmates to write a graduation thesis of about 10000 words without plagiarism, but we should at least try our best to avoid serious plagiarism subjectively and gradually form good habits.
