My summer holiday is coming to the end．During the holiday，we went to Dalian for a visit，I saw the beautiful sea there，it was really amazing．The sea water 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 I 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．
