I have made a new friends recently. His name is Jackson, and he is from the America. How did we get to know each other? You may think we are pen-friends, and you are wrong. We actually have never written to each other before we met. Here is the story. A week before, there was a summer camp in our school. Some American students came to join in us. I was very good on English, especially spoken English, so I was chosen to take part this camp. Jackson was very interesting in Peking Opera, and I liked it, too. When I told Jackson that, he felt very excitedly. We talked a lot about Peking Opera. He said he had a very good time and hoped he would come again quite soon.
