My name is Selina. I come from Beijing. I'm a Chinese girl. This year my parents go to work in London. They teach Chinese in a university. Do you know London? It' s a big city in England. I study in a middle school there. I'm in Class Four, Grade Seven. My teachers are nice to me. I can play the piano and the guitar. Sarah is my sister. She lives in Beijing with my grandparents. She studies in a primary school（小学）. She is in Class Three, Grade One. She likes singing. She can't sing English songs well. I often write to her. But she doesn't write to me because she can't write much. I miss her very much.
