Usually the introduction part of the paper will be repeated. Many college students don't understand it, mainly because they haven't been in contact with it before, and they don't pay much attention to the duplicate checking of papers.

Although the introduction of the paper is not the main part of the paper, it will be repeated and is a very important part of the paper. Therefore, everyone should pay enough attention to it and make high-quality revisions to reduce the repetition rate that will be found when the paper is repeated.

Of course, the text of the paper is the text, except the text, the introduction, abstract, keywords and appendix of the paper will be repeated. Everyone should write a good paper carefully, don't copy it, and improve the originality of his paper, so that he can pass the exam smoothly and quickly when checking the duplicate.

Introduction refers to the part that explains the main ideas and contents at the beginning of the paper. The beginning of a paper usually needs an introduction (also called preface, preface, preface, preface).

The task of the introduction is to explain the topic, the main direction of the paper, the process and situation of document retrieval (that is, what the predecessors have done in this regard), what innovations (or arrangements) their own papers have, the research methods used and the general structure of the paper, and other issues that need to be explained.

Common errors in modification:

1, knowing that W repeats more than 13 words in a row is plagiarism. Knowing that W repetition 13 or more is plagiarism; There is an "or" in these two sentences. If you check how many words are plagiarized, it is not a fixed number. Otherwise, long sentences with hundreds of words will be misjudged and plagiarized, and short sentences will be missed.

2. Delete all duplicates. If more words are deleted, the total number of words will be less, and the repetition rate is plagiarism divided by the total number of words.

3. Change the sentence patterns and the order of words. Repetition does not need to be continuous.
