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.

We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth.

Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.

Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.

When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.

According to the passage, the root cause for weather changes on the Earth is ______.

A. the atmosphere surrounding the Earth    

B. water from oceans and lakes

C. energy from the Sun 

D. greenhouse gases in the sky

Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.

   A. absorbed by the clouds in the lower atmosphere

   B. reflected by the gases in the upper atmosphere

   C. lost in the upper and lower atmosphere

   D. used to evaporate water from the oceans and lakes

We learn from the passage that _______________.

   A. all living things on the Earth depend on the Sun for their food

   B. a forest looks dark in winter because it absorbs solar energy

   C. only 0.023% of the energy from the Sun is made use of on the Earth

   D. greenhouse gases allow heat energy to escape from the Earth’s surface
