The annual English Festival, which was lasted one week, has just ended. There were all kinds of colorful activities, included an English speech competition. Last Friday, we had an honor of inviting Professor Smith to deliver a lecture on English cultural background information, such as English idiom. He was very learned and humorous that he began his lecture with an amusing story to attract the attention of the audience and all of us was deeply impressed with his wisdom. We admired him and took notes carefully, for he made himself understood with speaking slowly and clearly enough for us to follow her. He gave us some practically ways to develop the sense of language and encouraged us to keep speaking English as much possible in our daily life.
