How Sled Dogs Work
They're physical wonders-able to endure extreme conditions for extensive periods of time while running fast and pulling more than their own weight. Sled (雪橇) dogs have been around for generations, and today they remain a large part of a dog driver's life.
In Arctic (北极的) regions, some 35 000 years ago, Eskimos' dogs bred with wolves and other dogs. Their offspring were well-adapted to the cold and snow. There's no saying exactly when someone thought to have dogs pull sleds, but it was well before 1000 B. C. that dog sleds provided a means of transportation and a way to haul goods. In recent years, people looking for unique outings have gone on recreational trips with sled dogs. A number of companies market tourist treks via dog sled for adventure travelers.
Dogsled racing in Alaska formally began in 1908, when sled dog owners in Nome, Alaska, held the first All-Alaska Sweepstakes, a 408-mile race from Nome to Candle and back. And in 1973, the inaugural Iditarod Trail Sled Dog Race took place on a route covering more than 1 000 miles in Alaska. There are more competitions in many of the continental United States, and some take place on dry land. In addition to endurance races, sled-dog events include sprint races, weight pulls (in which dogs try to pull the most weight) and freight races (in which dogs try to pull a weighted sled the fastest).
Stamina (耐力) and Strength
Many breeds of dogs are used to pull sleds, including official American Kennel Club breeds such as the Siberian husky, Malamute and Samoyed. However, many sled dogs are of mixed breed and are called Alaska husky or Eskimo dogs. While some Sled dogs may have wolf bloodlines, it's generally not desirable to have a mixture of blood between the two.
Sled clogs are bred for their speed and endurance as well as leadership qualities. They are big dogs with thick coats and wide, flat feet. They sleep with their tails covering their noses to keep warm. Dogs that weigh around 40 to 45 pounds are the ideal size to pull sleds, but some may weigh as much as 85 pounds.
Young dogs that are enthusiastic runners, easy-going and mentally tough are good choices for sled dogs. A dog's gender matters little and both male and female dogs are considered equally.
For racing, the most intelligent and fastest dogs are picked to be lead dogs and run in the front of the pack. Behind them run swing dogs, whose job is to direct the team around turns and curves. At the back of the dog team are the wheel dogs or wheelers, who are right in front of the sled and are usually the largest and strongest of the team. The rest of the dogs are known simply as team dogs.
Dogs are typically from 2 to 10 years old when they pull sleds. After they retire, they might remain with their owner at a kennel or be adopted as pets by others. Rescue groups for sled dogs take in unwanted dogs and care for them, trying to place them in loving homes.
While snowmobiles (also called snow machines),helicopters and airplanes are now often used !n Place of sled dogs, there are still times when dog transportation is preferred. Harsh weather conditions can make flying hazardous, and certain terrain can be more difficult for snow machines to cross than for dogs. Dogs can be more reliable than man-made machines, they're good companions to have on long treks and they can be cheaper to own than other forms of transportation.
Becoming a Sled Dog
The number of sled dogs at a typical kennel(养狗场)is around 75, though some might house as few as 20 Or as many as 150. Many kennel owners are greedy mushers (赶狗拉雪橇的人) and compete in dog sled races. They also train other mushers and sell and lease dogs. The training for each team of racing dogs varies by musher (or whomever is preparing the dogs to race). Conditioning the dogs to run long d
A．Because they are raised by wolves.
B．Because they can stand most severe weather.
C．Because they are fastest runner among Arctic animals.
D．Because they can bear goods like horses do.

Two hours passed, during which Bob had heard Oolak's rifle crack four or five times. Bob decided to look for his companion and rejoin him. He climbed an ice pinnacle to look. It was a peaceful scene that met Bob's gaze. White ice stretched before him with little streams flowing across its surface. The low hills and open plains of ice were all bathed in golden sunlight. He did not see Oolak, but he became aware that the dogs had been howling for some time. It dawned on him that the entire team was in an uproar.
When he glanced his way to see what the trouble was, his heart almost froze. Walking toward them was an immense whitish form, sleek head hanging low--a polar bear!
The bear smelled a freshly-killed seal which Oolak had dragged to the sled, and it was this that he was seeking. To the clamor of the dogs he paid no more attention than if it were the buzzing of a fly. In his entire life the huge beast had never known fear, for the. polar bear is the ruler of the ice. He knows no enemies.
According to the passage, it is not easy to get seal
A．in water.
B．on the ice.
C．in the polar region.
D．on the pinnacle.

Farmers can also call on the services of their local hunt to control the fox population. Hunting consists of pursuing a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs finally catch the fox they kill it or a hunter shoots it.
People who take part in hunting think of it as a sport; they wear a special uniform. of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.
It is estimated that up to 100, 000 people watch or take part in fox hunting. But over the last couple of decades the number of people opposed to fox hunting, because they think it is brutal (残酷的).
Nowadays it is rare for a hunt to pass off without some kind of confrontation (冲突) between hunters and hunt saboteurs (阻拦者). Sometimes these incidents lead to violence, but mostly saboteurs interfere with the hunt by misleading riders and disturbing the trail of the fox's smell, which the dogs follow.
Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.
Rich people in Britain have been hunting foxes______.
A．for recreation
B．to limit the fox population
C．in the interests of the farmers
D．to show off their wealth
