     Dogs like living with people. They are very friendly. They can do many things for people.

     Some dogs help people to look after sheep, other dogs help them to find the lost children.

And some of the dogs can help the blind (盲人).

     There is a kind of dog. His name is Seeing Eye dog. Now we can see this kind of dog all

over the world. They are working for the blind. The Seeing Eye dog is strong and easy to train

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

(训练员) across busy streets. The dog has many things to learn. At the end of the training school,

he must take tests (测试). When he passes (通过) the test, the Seeing Eye dog will do things by
