After a week of practice, I finally mastered stopping, gliding, and stopping again on any incline.
经过一周的练习，我终于掌握了在任何坡度上停下、滑行并再次停下的技巧。
句子通过列举“stopping, gliding, and stopping again”这一系列动作，具体展示了技能掌握的细节和过程。
Only those who know how to stop know how to accelerate. Watching others ski, it always seemed so easy—wasn't it just sliding from the top of the mountain to the bottom? So, I put on my skis and shot down with a whoosh. The result was indeed getting from the top to the bottom, but the actual process involved tumbling down the slope and eating a lot of snow. Eventually, I repeatedly practiced how to stop on snow and slopes. After a week of practice, I finally mastered stopping, gliding, and stopping again on any incline. At that moment, I realized I truly knew how to ski and dared to charge down the mountain at high speed. This was because I knew that if I wanted to stop, I could turn and stop immediately. Therefore, only those who know how to stop know how to advance at high speed.
