In this tutorial, we learn how to avoid research paper plagiarism with quotations. Whenever you use a source, you can quote from it using the author's direct words, or you can paraphrase. Paraphrasing means putting something into your own phrases and sentences, because you will have to repeat certain key words. If you do this, you have to make sure you are not copying the quote exactly, and that it really is in your own words. You can't put something into your own words if you don't understand it. Remember to always use key words and cite everything you use!
