1) The ability to write well-organized, concise paragraphs is essential to a student’s success in almost all university courses. （Topic Sentence）In preparing scientific reports of laboratory experiments, a student must present his or her findings in logical order and clear language in order to receive a favorable evaluation of his work. In writing successful answers to essay questions on history or anthropology examinations, a student must arrange the relevant facts and opinions according to some accepted pattern of paragraph structure. And certainly in writing a book report for English, or a critique for political studies, or a term paper for sociology, a student must pay attention to the style and organization as well as the content. (Developing sentences) Clearly, skill in expository writing is crucial to successful achievement in most university subjects. (Concluding sentence)

American Society and Culture is another course that attracts a large audience. The teacher, who visited the United States not long ago, discusses new trends and changes in American life as well as American history and traditions. (Developing sentences)We like these and other courses very much, because they help us not only to improve our English but also to broaden our vision. (Concluding sentence)
