This paper is concerned with expression in composition. Expression includes the unity, coherence, and emphasis/purpose of a paper, and its style and/or tone. The paper first gives four alternative definitions of style and offers some specific components of style, such as word choices, sentence structures, and imagery. It then presents and discusses the following common problems related to style: wordiness; redundancy (related to wordiness); excessive use of "who,""which,""that"; unnecessary intensifiers or hedges; too many prepositional phrases; overuse of "be"; overuse of the passive voice; choppy sentences; and lack of sentence variety. Finally, the paper enumerates and elaborates 10 ways to overcome problems and improve style: (1) modeling; (2) imitation; (3) word games; (4) using figurative language; (5) sentence combining; (6) expanding sentence versatility; (7) sentence imitation; (8) sentence variety; (9) copy change; and (10) role play the registers. Contains an 11-item bibliography. (NKA)
