这是和另一段一起的吧?
总之,游泳是一项对身体有很大好处的体育锻炼我们应该要多参加.As a whole swimming is a physical training item that id very beneficial to our body, all of us should take part in it more.一般说来我都是暑假去游泳的,每次有用时间都不会超过2-3小时,每隔半小时我都会休息一下.Generally I have swimming in summer vacation, take less than 2~3 hours each time, and have a rest at an interval of about half an hour. 再下水前都会做好准备运动,不再饭后1-2小时内游泳 I always have good preparation before getting into water again, and pay attention to avoiding swimming within 1~2 hours after meals.
