Last summer, I went to Qingdao with my parents. We took the high-speed train and it took us only an hour to get to Qingdao. It was a beautiful city. The sky was blue and the air was fresh. On the second day after we got to Qingdao, we went to one of the most famous beach①. I was so careless that I lost our camera on the bus. We were very worried, so we got back②the bus station to look for it. To our surprise, we found a young man stand③beside the bus, with our camera in his hand. We were so thankful.
