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 Tianjin. After that they asked me a lot of things about China. But             I couldn’t explain them with 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. I must work hard to improve my spoken English so that I will not be able             to communicate freely with foreigners. I hope I can be a bridge between China and others countries in the future.
