This autumn my class went to Dalian to go the camping. We arrived at a sandy beach with a well view of the sea. We set up our tents on the sandy beach, when night fell we made a fire to give us light and kept us warm. All the classmates sat around them, talking and laughing. Several hours late, Li Mei and I went
back to the tent to have a chat. We stayed up all of night. We found that we two had a lot of common. For instance, we both like the same singers and have great enthusiasm for physics. The fire and the stars see
our happiness. What I wished time would stop at that moment!
