Next on your sheet of paper, create a second column that will contain words and phrases that provide context for the nouns in your first column. For example, these are the answers to the questions:
What is this paragraph about? (Note the answer may not be specifically named in the paragraph at all, since the real subject may be provided by the section or a paragraph above it.)
What is this section about?
What is the current chapter about?
Anything at all that comes to mind about the context should be listed in this second column.
Also, each noun in the paragraph has a more local context.
Do this for EACH noun listed on the left, and if needed, draw lines connecting the nouns with their context entries (there can be 0, 1 or several context entries per noun in the left column). Leave plenty of vertical space between these entries as well.
For our example paragraph, or sheet of paper now looks like this (I use an elipsis [...] to replace the context term):
water
percentage in body (from "percent")
body holding onto it (from "it")
lack of (from "it")
not drinking enough (from "enough")
drinking enough (also from "enough" later in paragraph)
