简答题。

     阅读下面短文, 根据第1-3小题的具体要求, 简要回答问题。

     Every January, Breckenridge hosts the International Snow Sculpture Championships. Fourteen teams travel

from all over the world to Switzerland to compete. Teams sculpt for sixty-five hours over five days. Each team hopes that when the time is up, its sculpture will be judged the best.

      As the championship begins, the fourteen teams are faced with huge blocks of snow that weigh twenty

tons each. The sculptors bring out their favorite tools that work best on the hard iced snow, but they are not

allowed to employ tools that use electricity.

     Most teams are inspired by what they have seen in daily life. For example, one team carved a teapot with

tea pouring out. Another team sculpted a little cat on its hind feet (后脚) reaching into a fish bowl complete

with water ripples (涟漪) and a crab (螃蟹) trying to attack the cat. In 2006, Team USA sculpted a golden dog

looking at its image reflected in a mirror. To create the effect that the little dog saw its reflection in the glass,

the artists carved two dogs facing each other with their paws (脚爪) touching.

     As the final hours of the competition tick by, exhausted team members add last-minute detail. They use

small brooms to brush off snow caught in tiny holes. One team member counts down the last five minutes

while others are busy cleaning up the tools. If they leave any tools behind, they will be out. When the whistle

bows, everyone must step away from the sculpture. The judges then vote on creativity, technical skills, and

visual impact (视觉效果)of the designs.

     In 200, Team USA took first place for their golden dog sculpture titled"Discovery". But the competition is

not just about medals and ribbons. "It's not about the prize," said Rob Neyland, Team USA's captain."It's about

touching the audience."

     Every year, as the championship ends, each team is already dreaming of the next masterpiece it will design.
