我们居住在一个水占四分之三面积的蔚蓝色球体上。没有水,就没有人类的生存与发展;征服水,也成为人类千百年来的梦想。作为反映人与自然在斗争中和谐并存关系的奥运会,游泳等水上项目自然成为最受关注的金牌大户。 We live in a blue sphere that occupies three quarters of an area. Without water, there is no human existence and development; conquest of water, has also become a human dream for thousands of years. As a reflection of the harmony between man and nature in the struggle of the Olympic Games, the swimming and other water projects naturally become the most watched gold medalist.
