     Dogs like living with people. A dog can be a best friend. He will do a lot of things for people. Some dogs

help people to look after sheep,and others help them to find the lost,things. And some of the dogs can help the

blind (瞎的,盲的) men or women do things.

     Many years ago there was a very good dog. His name was Seeing Eye dog. Now we can see this kind of

dogs all over the world. They are working for the blind.

    The Seeing Eye dog is strong,good and easy to train (训练). He helps the blind to walk from place to place.

     Before a dog becomes a Seeing Eye dog, he must go to a training school for about three months. First the

dog has to learn to sit or stay when he hears the trainer's call. In his next lesson the dog learns to take his

trainer across busy street.

     The dog has many things to learn. And in every lesson he must learn to do one thing again and again for

many times.

    At the end of the training school he must take tests (测试). When he passes the final test, the Seeing Eye

dog is ready (准备好) to do things by himself.

     Now he is ready to help a blind person. The new master (主人) may be a man, a woman, or even a child.

It takes the dog and his blind master about a month to learn to work and live together.
