This term several useful and interesting courses have been offered. An introduction to European Culture, for instance, gives us a lot of background knowledge of the history of European philosophy, literature, an arts. From time to time we see slide shows of famous paintings and hear tapes of famous pieces of music, and they make the lectures all the more interesting . 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 tradition. We like these and other courses very much, because they help us not only to improve our English but also to broaden our visions.
