Sometimes when reading a passage, one can become hindered in progress by difficult terms or difficult ideas.  When one prereads, one will look over the passage for bolded terms, headings, and maybe even the summaries at the end of the passage in order to gain a preliminary understanding of the content.  With this basic understanding of passage content, one will gain a bit of familiarity with content to where it will not be as difficult/challenging when reading the passage the entire way through.
