The differences between American and Chinese in doing research

Nobody can deny that it should be very easy to do a research for student in China. The reason is because most teachers just want to get your homework as the result but not to consider the origin of them. Maybe the situation is being changed in China, in my opinion, it is totally different in America.
In America, The plagiarism is treated more seriously than that in China. For example, for my experience in America, I did not know how serious the plagiarism is in America when I just came in America. In a writing homework, I just used some sentences from the Internet and did not mention the origins of them. What is more, I just copied them into my article and never changed them at all. For a result, the teacher punished me very seriously. From that time, I started to recognize this situation in America. Additionally, in newspapers or every kind of magazines, no matter how short the article is, they must type on the authors' names or their origins. I am so glad to see that. As people focus on protecting the copyright, more and more articles are being published by the talent authors. Also, everybody is honest for their study or anything else.
