Dear Jack，
We had a lovely holiday on the seaside the day before yesterday. I went fishing and flew kites by the sea. It was windy and warm here. I swam, built sandcastle( 沙堡) with my brother Tom and went sailing with my parents. That was exciting! How about your holiday? What do you do every day over your summer holiday? Please write to me and tell about it. See you when I get back.
