I've got good news to tell you. This summer vacation my parents and I will go to Shanghai to visit the pavilions of the World Expo. We have already bought the train tickets. We will leave Yinchuan on July 15 and arrive in Shanghai on July 17. We will stay in Jiangtian Hotel which is about 4 kilometers away from the pavilions. During the next two days we will visit the pavilions. We plan to return to Yinchuan on July 20. I will be free on the evening of July 19. Can we meet then? I am looking forward to seeing you.
