    Skin­diving is a new sport today. This sport takes you into a wonderful new world. It is like a visit to the moon. When you are under the water, it is easy for you to climb big rocks, because you are no longer heavy.

    Here, under the water, everything is blue and green. During the day, there is plenty of light. When fish swim nearby, you can catch them with your hands.

When you have tanks of oxygen on your back, you can stay in deep 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.

    What's more, there are more uses for skin­diving. You can clean ships without taking them out of water. You can get many things from the deep sea.

    Now you see that skin­diving is both useful and interesting.

李某路过蔡某家门口，被蔡某养的狗咬伤，花去医药费1 500多元。李某找到蔡某，希望蔡某承担医药费。蔡某却说：“我家养的狗拴在树上，从来没咬过人，这一次怎么会断了绳子咬人？一定是你逗我家的狗，并割断了拴狗的绳子，所以狗才咬人的。你是自作自受，责任该由你自己承担。”李某深感气愤，却又不知该如何解决。
