I went to the Summer Palace on last week. At the gate I happened to meet some American tourists. I greeted him in English and then we began to chat. I got to know that they were college students travel in China. I proud introduced some famous places to them. They were busy taking picture and were impressed with the amazed changes of China in the past few years. After that, we go boating on a lake and had good time. We exchanged our email addresses so that we could write to each other in the future. They thanked me again and again and said they would never forget the time when we spent together. I was very glad to have a chance to practising my oral English.
