Skin-diving (潜水) is a new sport today. This sport takes you to a new wonderful world. It is like a
visit to the moon! When you are under the water, it is easy for you to climb big rocks (岩石), because you
are no longer (不再) heavy.
Here, under the water, everything is blue and green. During the day, there is enough light. When fish
swim nearby, you can catch them with your hands. When you have a tank (罐) of air on your back, you
can stay in deep (深) water for a long time. But you must be careful when you dive in deep water. To catch
fish is one of the most interesting parts of this sport.
