plagiarism tutorial

In the plagiarism tutorial, there are 10 questions about several issues on the plagiarism. However, there is one question that I have interesting, which is the question 8. Specifically speaking, question 8 is about if your teacher ask you to post something on a class list online, as well as you find an essay and want to copy and paste to your posting. Furthermore, the question is ask you weather this is plagiarism or not. So, my answer for this question is yes, because when you use someone's article, you must use this person's idea. So, if you use his article without any citation, it means you stealing other people's properties. In this question, I think it is not quite formal academic situation, so some of the people would think that copy and paste other people's idea is not a plagiarism in this informal situation. Finally , these people would commit copying and pasting others' work. In contrast, the behavior copying and pasting others' work defined as the plagiarism in every single area not just only in academic area. After understanding this question clearly, I know that people should think more carefully about what they use in their own article. Finally, I know that every area that need writing paper should focus on the plagiarism issues.
