One writing teacher compares the task of a writer to that of a tour guide escorting a group of sightseers who do not have to pay their fares until they arrive at their destination and get off the bus. The job of both the author and the tour guide requires that they keep their audiences so interested in what is going on that they will stay until the end of the journey. Readers, like tourists, are capricious and impatient, and they will go off and do something else if they get confused, bored, or led off on a detour that seems pointless to them. When you write, you may find it helpful to keep this analogy in mind and from time to time ask yourself, "Are my readers liable to get off the bus here? And writers, like tour guides, must keep their audiences oriented. If there is any way for readers to get lost, they will! All writers need to keep this caution in mind as they write (especially their second or third drafts) and to work consciously to help their readers stay on track as they are reading. Once they stray, they are hard to recapture. For that reason, a writer needs to have some specific strategies to hold readers' attention. Process analysis: ___________
A.
directional process
B.
informative process
