In other words, narrative reports often overlook the author s purpose or point of view expressed through the book or article. The purpose of an expository essay is to present, completely and fairly, other people's views or to report about an event or a situation. Such writing is discourse designed to convey information or explain what is difficult to understand. Exposition usually proceeds by the orderly analysis of parts and the use of familiar illustrations or analogies. In other words, you must write clearly and fully enough for your readers to know how you have arrived at your analyses and conclusions.
Accurate analysis is a fundamental professional activity in almost all careers.
Like any other fundamental skill, it must be constantly practiced in order to maintain and improve it. The purpose of a critical essay is to state your reasoned opinion about someone else's work or an event, including its often unstated assumptions or point of view. Criticism is the art of judging or evaluating, with knowledge and propriety, the beauties and faults of works of art or literature. The idea is extended to the similar consideration of moral values, of the the soundness of scientific hypotheses and procedures, etc. You can write a critical essay that agrees entirely with the reading.
