如何用英语介绍冲浪运动并保持平衡？

Surfing is the term is used for a surface water sport in which the person surfing moves along the face of a breaking ocean wave, known as the "surf". However, surfing is not restricted to saltwater, but can sometimes take place on rivers, using a standing wave. The main use of the word "surfing" is for riding waves using a board on which the surfer stands. Other forms include bodyboarding, where the individual only partly raises his upper body from the board surface, and bodysurfing, where no board at all is used.
