听力原文： It's not known exactly bow or why humans domesticated the first dogs. But once tamed, people found them useful and they learned how to selectively breed for certain traits to create animals fit for specific task. Most likely, the first dogs were used for hunting and protection. Some were bred to chase down prey, others to herd livestock. Today's most popular breed, the Labrador, was originally bred by fishermen to haul nets and retrieve fish. But at some point, humans also started to breed dogs for looks and for companionship. Brian has wondered why of all domesticated animals, dogs seem closest to their owners.
Somehow during the long relationship together, dogs learn how to communicate with humans. And they pass the skill down to each succeeding generation. It turns out puppies can understand human gestures even if they've been raised in the wild, while wolves raised in captivity just don't get it. It's a unique skill that perhaps only dogs possess.
What special tasks were not the first dogs bred for？
A．Hunting and protection.
B．Chasing prey.
C．Herding livestock.
D．Keeping accompany.

听力原文： When you walk in any of the cities in the West, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog have changed. In the past people used to train dogs to protect themselves against attacks by other beasts. And later they came to realize that a dog was not only useful for protection willing to obey his master.

Why do they keep dogs, then？ Some people keep dogs to protect themselves from robbery. But the most important reason is for companionship. For a child, a dog his best friend when he has no friends to play with. For young couples, a dog their child if they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection to friendship.

听力原文： Where did the term Piggy Bank come from？ Today the simple piggy bank is seen everywhere as the symbol of saving and frugality, for putting away funds for a rainy day, or building a nest egg for life's sudden money needs, such as paying college expenses, buying a home, or financing retirement. But why a pig？ Dogs bury bones for a rainy day. Why not a dog shaped bank for coins？ Squirrels are well known hoarders too and we talk about squirreling away valuables, why not a bank in the shape of a squirrel？ Well nevertheless, for 300 years, children's banks have been imitation pigs with slots in the back. Charles Bernardy, the author of Extraordinary Origins of Everyday Things, tells how the symbol came about by coincidence. According to Bernardy, during the middle ages, mined metal was scarce and expensive, therefore was rarely used in the manufacture of household utensils. The type of orange clay, known of pygg, spelt p-y-g-g, was more abundant and economical throughout western Europe. It was used in making dishes, cups, pots and jars. And so these earthenware items were referred to as pygg. Frugal people saved cash in kitchen pots and jars. Although a pygg jar was not originally shaped like a pig, the name persisted. However, by the 18th century, pygg, p-y-g-g jar became pig, p-i- g jar or pig bank. Potters had simply begun to east the bank in the shape of its common name. In the United States, the popular piggy bank has always been a symbol of saving money.
