Last night we talked about swimming, which remind me of last year. I like to go swimming every summer in my hometown now, because I like to touch the water as well as the sea.I enjoy the soft water and the feelings of floating. Diving is also a very happy thing. In almost summer vocation I came to swimming pool for more than 30 times even since I was 4. But I can't swim in the sea because of my hometown hasn't the sea. Will you describe something differnt from swimming in the sea and in the river or in the swimming pool?
