Horses are used in guarding herbs, carrying men in lands where there are no roads, and helping farmers work their land. Pigeons have long been used to carry messages. Wild animals from the jungles, forests and seas are very popular performers in circuses and moving pictures. People realize that, although animals may not have the same intellgence as human beings, they are smart enough to know certain things.

Horses are also able to learn many things. Homes that are used for guard or police duty must learn never to be frightened of noises, traffic, and other disturbances. Racing horses are able to run much faster than other horses, but they are also quite high strong. Therefore, it is necessary for those people who train them to be very patient and understanding.

Pigeons have a natural instinct to return home, even if they are very far away and the trip is hard or dangerous. Men utilize this homing instinct to send messages on small pieces of paper which are fastened to the pigeons’backs or legs. In war time, pigeons have been known to fly as fast as 75 miles an hour and to cover distances of 500 to 600 miles. These homing pigeons begin their training when they are about four weeks old. After a few weeks they can begin flying and carrying messages. If all goes well, their flying career lasts about four years.

Animals can learn to do many things that, while not necessarily useful, are very amusing to watch. In circuses, animals are taught to do the tricks that are most suitable for their physical and temperamental make-up. Lions and tigers can be taught to leap and spring gracefully when told to do so, or to stay in place on command. Elephants leant to walk in line, to stand on their hind legs, to lie on their sides, and to stand on their heads. They can also learn to dance.

Once a trainer had an elephant and a tiger. After many weeks of living in the same cage, the two animals became accustomed to each other. Then the tiger was taught to jump on the elephant’s back. Both animals became so interested in the act as well as the praise and food they received after the act, that they for-got they were natural enemies. Later a lion was added to the act. This also took a lot of patient training. How ever, when the three animals grew accustomed to each other they made a most successful Circus act.

Race horses are hard to train because they are ______.

A．faster than other horses

B．smaller than other horses

C．more suspicious than other horses

Earthquake and Animals

Scientists who try to predict earthquakes have gotten some new helpers recently —animals. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a quake 地震) in China in 1975 snakes awoke from their winter sleep early only to freeze to death in the cold air. All the unusual behavior, as well as physical changes in earth, alerted (提醒) Chinese scientists to the coming quake. They moved people aw/ay from the danger zone and saved thousands of lives.,

One task for scientists today is to learn exactly which types of animal behavior. predict quakes. It is not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1979, for example, an Arabian horse became very nervous and tries to break out of his stall. The horse next to him, however, remained perfectly calm. It is also difficult sometimes to tell the difference between normal animal cahnness and "earthquake nerves". A zookeeper once told earthquake researchers that his cougar (美洲獅) had been acting strangely. It turned out that the cougar had a stomachache.

A second task for scientists is to find out. exactly what kinds of warning the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can detect tiny changes in air pressure, gravity, or the magnetism (磁力) of earth. This extra sense probably helps animals predict earthquakes.

A good example of this occurred with a group of dogs. They were closed in an area that was being shaken by a series of tiny earthquakes. Before each quake a low boomingsound was heard. Each sound caused the dog to bark (吠) wildly. The dogs began to bark during a silent period! A scientist who was recording the quakes looked at his machine. He realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing.

In this case there was a machine to check what the dogs were sensing. Many times, however, our machines record nothing out of the ordinary, even though animals know a quake is coming. The animals might be sensing something we do measure but do not recognize as a warning. Discovering

what animals sense, and learning how they know danger signals, is a job for future.

During an earthquake in China in 1975, more cows had ,'earthquake nerves" and some remained calm.

C．Not mentioned

聽力原文： On local news, Klondike Valley Park will officially open its trails to mountain bikers on Monday. For years, the trails were restricted to hikers and people on horseback. This will be a positive change for mountain bikers, as they were banned from these trails. Many bikers have been fined for riding on these trails which they feel should be free to everyone. Many hikers, however, are not pleased with sharing the trails. They feel the extra traffic will increase damage to trails. Bikers feel the opposite; saying that they actively volunteer time to build and repair trails.

What is the report about?

A．Mountain biking is a popular sport.

B．Mountain bikers do not respect trail rules.

C．More restrictions will be imposed on mountain bikers.

D．Restrictions on trails have been lifted for mountain bikers.
