Sometimos practice in writing sentences may seem tedious and rather artificial. After all, people rarely write pieces of comunication that consists of a single sentence. But the method may not seem so strange if you have had the opportunity to learn a skill already.Practice in writting sentences, then, is a way of becoming fluent and handling the basic units that are necvessary for any piece of writting. The first step to become a skill writer is to learn to write good sentences. (HART Kathleen A. And HEIM Alice C.)
