My summer holiday is coming to the end. During the holiday, we went to Dalian for a visit, l saw the beautiful sea there, it was really amazing. The seawater was as blue as the sky, and it was very clean. Also, the beach in Dalian was very nice, we built a small sand palace. When I was swimming in the sea, as if l was a little fish. I like that feeling very much. I also spent time to study for school. I read many books, practiced math problems, and I finished all of my homework. I was very happy.
