Accurate paraphrasing requires careful attention to the nuance and meaning of words. The ones you choose must reflect the meaning found in the original source without plagiarizing its author.
The key to this begins with your own comprehension. How well you understand the contents of a passage will determine how accurately you restate it in your own words. Using sentence structures and rhythm patterns that are uniquely your own will distinguish your voice from the ones you paraphrase.
When you are through there should be no mistake regarding the speaker's identity. The following example illustrates accurate, inaccurate as well as inappropriate paraphrasing.
