听力原文： The dog has often been an unselfish friend to man. It is always grateful to its master. It helps man in many ways. Certain breeds of dogs are used in criminal investigations. They are mined to sniff out drags and bombs. They help police to catch criminals.

The dogs that help in criminal investigations are trained at a school called the Military Dog Studies Branch of the U.S. Air Force in Lackland, Texas. The dogs to be trained are selected by an air force team. This team visits large cities across the country to buy the dogs. They may buy dogs from private citizens for up to $750 each. Some citizens freely give their dogs. The dogs selected must be healthy, brave and aggressive. They must be able to fight back if they are attacked. The dogs chosen are between the ages of one and three. They are given a medical examination when they arrive at the school. Their physical examination includes X-rays and heart tests. The trainee dogs undergo the first stage of training when they arrive in Lackland. This is an 11-week course for patrol duty. After this course, the best dogs are selected to go on another 9-week course. They learn drug-sniffing or bomb-sniffing. After this course, the dogs are ready for their jobs in the cities or on air force bases.

The training given to a drug-sniffing dog is different from that given to a bomb-sniffing dog. A drug-sniffing dog is trained to scratch and dig for the drags when he sniffs them. A bomb-sniffing dog sits down when he finds a bomb. That is the alert for hidden explosives.

(23)

A．Given by the local government.

B．Born by a large number of bitches.

C．Bought from different cities and villages.

D．Captured over grassland.

听力原文： When you take a 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 old days 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 but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission. But now people in the city need not protect themselves against attacks of animals. 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 is his best friend when he has no friends to play with. For young couples, a dog is their child when 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.

(33)

A．For protection against other animals.

B．For protection against other dogs.

C．Just for fun.

D．For the purpose of guarding the house.

听力原文： Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give him protection, and some do hard work which man cannot do for himself.

Trained and tamed for many generations, domestic animals are not accustomed to wandering in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.

All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps, and then wonder why the animal seems listless and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.

Cats and dogs do not need a place of their own, although a very big dog is better off in a doghouse than in the house. The cat, an independent creature, is very good at finding the safest and most comfortable spot when she wants to take a nap. But cows and horses and similar animals must have proper stables, clean, dry and well ventilated.

Even well cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.

(33)

A．Looking for food by themselves.

B．Being fed properly.

C．Overfeeding or underfeeding.

D．Living on people's odds and ends of table scraps.

"As many as fifteen homes have been destroyed and hundreds more damaged in the town of .Seward, .southeast of Anchorage.

Rain is forecast to continue for at least another day in Seward. Meanwhile, north of Anchorage, two bridges have been washed away, and the Alaska Railroad, a major form. of transportation between Anchorage and Fairbanks has been cut off, making it very difficult for residents in interior Alaska to get to five.

For National Public Radio, this is Tim Wolston in Anchorage, Alaska."

听力原文：（32) Leona Bridges, a New York woman who married into millions, left her mansion

听力原文： (32) Leona Bridges, a New York woman who married into millions, left her mansion and her $12 million fortune to her pet, a little white Chihuahua named Duchess. Although Leona has one son, Wilbur, and three grandchildren, they received nothing in her will.

(33)Wilbur was not surprised. He had already hired a lawyer to fight the will. The lawyer said there would be no problem proving that Leona wasn't "all there" when she signed her will. No one, said the lawyer, in their right mind could be so cruel to their own flesh and blood while being so generous to a dog that had been rescued from an animal shelter. "The dog doesn't even have papers," said the lawyer.

Leona had not spoken to Wilbur in five years. They used to get along very well. Then Wilbur made an unfortunate joke. He was visiting Leona one afternoon. She had just spent $ 400 at a dog beauty parlor. The employees had washed, shampooed, and blow-dried Duchess, and then tied a big pink ribbon around her neck. Leona mentioned to Wilbur how beautiful Duchess looked. Wilbur said, "Yes, if your idea of beauty is a large rodent with a pink ribbon around its skinny neck. "Leona gave him a dirty look.

(34) Wilbur apologized, saying he was just joking, but Leona told him to leave immediately. How dare her son belittle her "baby"？ She didn't respond to any of his emails or phone calls. Leona told her staff to never use the words "Wilbur" in her presence. (35)Days later, she fired her housekeeper when he said he was going to "polish the silver" —she thought he said he was going to "watch for Wilbur". The housekeeper had worked for Leona for 25 years.

(33)

A．Her only child, Wilbur.

B．Her soil and grandchildren.

C．Her pet dog, Duchess.

D．Her grandchildren.

M: In the United States, each state has a law that says blind people using canes or dogs have the same rights of public access as the sighted.

You can ask if any help is needed, but understand that the answer may be "no", Blind people, if they have learned to use a cane or dog and travel independently, may not need help. It is important not to grab someone who is blind. If a blind person wants help, he or she may take your arm, or simply walk beside you. Some blind persons may have a harder time hearing the cars and traffic, especially if there is construction or a lot of noise around the area. Then they might want help that they might not need at other times.

W: Should I help a blind person to a chair？

听力原文： Americans love pets. Many pet owners treat their furry friends as part of the family. If they have an eye for fashion, pet owners can dress their pets in stylish clothes. For special occasions, they can use perfume to make their dogs smell well. You might say Americans treat their pets like they treat their children—sometimes even better. In America, there are more households with pets than those with children. At least 43 percent of U. S. homes have pets of some sort. Exotic creatures, such as monkeys, snakes and even wolves, find a home with some Americans. More common pets include tropical fish, mice and birds. But the all time favorites are cats and dogs, even at the White House. The Bushes’ dog, Spot, has replaced the Clintons’ cat, Socks. Leading a dog’s life in America isn’t such a bad thing. Many grocery stores sell delicious pet foods to owners eager to please their pets. In Houston, Texas, dogs can have their dinner delivered to their homes, just like pizza. Pets can even accompany their owners on vacation. Fancy hotels are beginning to accommodate both man and pets. Furry guests in hotels can enjoy delicious meals served on fine china and sleep in soft beds. The average American enjoys having pets around, and for good reasons. Researchers have discovered that interacting with animals lowers a person’s blood pressure. Dogs can offer protection from burglars and unwelcome visitors. Cats can help the home get rid of pests. Little creatures of all shapes and sizes can provide companionship and love. In many cases, having a pet prepares 32 a young couple for the responsibilities of parenthood. Pets even encourage social relationships: They give their owners an appearance of friendliness, and they provide a good topic of conversation.

(33)

A．Presidents like to keep pets.

B．Pets can offer protection for owners.

C．Pets can encourage social relationships.

D．Pets are good companies to many old people.
