A woman was at the cinema, and she was enjoying(享受) the film very much but there was a man in the next seat. He was looking for something. The woman was angry and said to him in a low voice(低声地), "What are you doing here? What are you looking for?" "A piece of chocolate!" the man said. "I have dropped(掉) it on the floor." "A piece of chocolate?" the woman said angrily." It's dirty now! Take this and be quiet, please." She gave her chocolate to the man." But my teeth are in the piece of chocolate on the floor."
