阿呆,关于越野滑雪:
From its origins over 5000 years ago in Scandinavia up to the early 1900s, SKIING was mainly a form of winter transport. Although a few daring athletes intentionally challenged their skills by SKI JUMPING or racing down hills, most of the early ski pioneers simply toured "cross-country" over relatively flat routes.
During the 1970s people caught up in the FITNESS boom or rebelling against the expense and congestion of alpine skiing took up cross-country in great numbers. The CANADIAN SKI MARATHON, for example, grew from 400 to over 4000 participants during that decade, and scores of other tours and races for the general public sprang up across the country.
During the 1980s and 1990s, technological innovation has changed the sport. Simple waxing systems and no-wax skis have reduced the complexity of ski preparation. Synthetic materials have allowed the manufacture of extremely light, strong skis and poles. New boot-binding systems improve control at high speeds. Since the new skis glide much faster, skating and double-poling techniques have assumed increasing dominance of international competition. In the mid-1980s, in fact, a separate "classical" racing category was created to preserve the traditional techniques apart from the faster "freestyle" skating. The skating technique is also popular with recreational skiers using prepared trails, since it is relatively simple to learn and requires no gripping waxes, only gliders. Although technology has simplified the sport on the recreational side, it has increased the complexity for elite racing. The choice of equipment and the process of ski waxing is now an acquired "art" involving a wide array of glide and grip waxes for all snow conditions.
Despite the increasing cost and sophistication of the competitive sport, cross-country skiing remains extremely popular with its almost 4 million Canadian participants. More than half of them set forth at least once a week to rediscover the age-old joys of the sport.
