前言

嗨喽~大家好呀，这里是魔王呐 !

 

 

滑雪运动（特别是现代竞技滑雪）发展到当今，项目不断在增多，领域不断在扩展。

世界比赛正规的大项目分为：高山滑雪、北欧滑雪（Nordic Skiing，越野滑雪、跳台滑雪）、自由式滑雪、冬季两项滑雪、雪上滑板滑雪等。

纯竞技滑雪具有鲜明的竞争性、专项性，相关条件要求严格，非一般人所能具备和适应。

 

 

旅游滑雪是出于娱乐、健身的目的，受人为因素制约程度很轻，男女老幼均可在雪场上轻松、愉快地滑行，饱享滑雪运动的无穷乐趣。

 

 

而近年疫情限制行动半径，只能在附近寻找乐趣，于是今天我就来分享一下滑雪代码~

读书多了，容颜自然改变，许多时候，

自己可能以为许多看过的书籍都成了过眼云烟，不复记忆，其实他们仍是潜在的。

在气质里，在谈吐上，在胸襟的无涯，当然也可能显露在生活和文字里。
