Skin-diving(潜水) is a new sport today. This sport takes you to a wonderful new world. It’s like a visit to the moon! When you’re under the water, it’s easy for you to climb big rocks(岩石) because you aren’t heavy any more.
Everything is blue and green under the water. During the day, there’s enough light（光）. When fish swim nearby, you can catch them with your hands.
When you have tanks of air(氧气罐) on your back, you can stay in deep water for a long time. But you must be careful, when you dive in deep water.
It’s the most interesting part of this sport to catch fish. There are most uses for skin-diving, too. You can clean ships without taking them out of the water. You can get many things from the deep sea.
Now you see that skin-diving is both useful and interesting.
