Here's why:
* Paraphrasing and summarizing are about re-expressing information in your own words. Using "exactly" implies you are copying the original wording, which defeats the purpose.
* "Exactly" suggests a direct quote. If you want to use the original author's words, you need to put them in quotation marks.
Here are some key words that are helpful for paraphrasing and summarizing:
* "In other words..."
* "Essentially..."
* "To summarize..."
* "The main point is..."
* "The author argues..."
