Last summer I go to America and studied at a language school. I had many wonderful experience, but I also had a sad one. One day, the school held party, where I invited to talk about Beijing. After that they asked me lots of things about China. But I couldn’t explain it in English

clearly. I felt sadly. I learnt a lesson from this experience. I have already studied English for eight years, I can’t use it very good.
