一道英语阅读题
People realize that, although animals may not have the same intelligence as human beings, they are smart enough to learn certain things.
Dogs are extremely useful as companions for blind people. When a dog has been properly trained, he will always lead his blind master in the right direction and keep him out of danger. For example, seeing-eye dogs learn never to cross a busy road when cars are coming even if their masters command them to do so.
Horses are also able to learn many things. Horses 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-strung (易紧张的). Therefore, it is necessary for those people who train them to be very patient and understanding.
The moving pictures and television can use trained animals too. Some animals, such as monkeys and foxes, are easy to film. All you have to do is to make a trail in front of the camera by dragging something that smells good to the animals over the ground. Big animals, such as lions and tigers, can be photographed as they bound happily back to their families and dinner. If a movie actor is nearby, the well-trained animal will pay no attention to him.
