When paraphrasing and quoting in ERH-101 you should always leave in text citations to avoid unintentional plagiarism.  While you paraphrase avoid just switching some work because that is still taking the original authors sentence structure which still is plagiarism.  You should always when quoting try to use the neutral signal verbs for example lists, describes, reports, etc.. And do not forget to give credit to the author if you quote or you will be in big trouble.
