听力原文：Your assignments this term will be to write two major research papers. One of the

most important things about writing a research paper is giving proper credit for your sources of information. Failure to do this is called plagiarism, which is a form. of dishonesty.

Plagiarism is a kind of stealing or at least an unauthorized borrowing of someone else's ideas. Sometimes inexperienced students will plagiarize unintentionally, and then be surprised when the teacher won't accept their papers, or gives them a failing grade.

The best way to avoid unitentional plagiarizing is to be very careful in gathering your informatiori. As you take notes on books and magazine articles about the topic you've selected, first try to assimilate the information thoroughly. Secondly, write it down in your own words. This is called paraphrasing. If you do a good job of paraphrasing, you'll capture the main idea from your source without actually using any phrases from it. Most of your notes should probably be paraphrases. However, occasionally you may find something you wish to quote directly in your research paper. In this case, be sure that you copy the quotation precisely in your notes and enclose it in quotation marks. That way when you're finalizing your research paper, you'll be able to remember which of your notes are directly quoted. You can incorporate them appropriately and give the original author proper credit.
