A seeing-eye dog is a special dog which helps blind people．代目狗是专门用来帮助盲人的导盲犬。
We call these dogs “seeing-eye” dogs because the dogs are the “eyes” of the blind man and they help him to “see”． 我们把这种导盲犬称之为“代目狗”，因为它们是盲人的“眼睛”，帮助他们“看”东西。
These dogs generally go to special schools for several years of training．通常，这些狗要到特殊的学校接受几年的训练。
One day a seeing-eye dog and a blind man got on a bus together． The bus was full of people and there were no seats．一天，一只导盲犬和一个盲人一起乘坐巴士。巴士上坐满了人，没有剩余的座位。

The blind man then sat down and the dog got up on the seat next to him．
