    Last week, my parents took me to the seaside. As soon as we reached the beach, I ran to the sea and jump in the water. The water rolled away from us. I still remember the sound of the water hit the beach and the foam (泡沫) of water as foam in soda or beer. I looked along the beach for shell to collect. I found a beautiful one, but sudden the owner of the shell appeared from inside. I was so surprising! My father told me to leave it since it was dangerous animal. When we went home, I decided I should return all the shells back to the beach to be part of the home of crabs.
