Maybeth Hearn, from the USA, was a 10-year old girl. She asked her parents if she could train a dog to become a guide dog. She didn't know that it would turn into a lifelong mission (终身使命) for her.
When young Hearn started training her dog, she met some problems. Her mother didn't like dogs and her father told her the training would need a lot of money. But Hearn didn't give up. Through hard work, on a sunny summer day in 1962, Hearn took a black dog home and began training it. In more than 50 years, Hearn trained 56 dogs on her own.
But Hearn, who was a high school teacher, did more than that. She inspired (鼓舞) her students to train more dogs. Since 1992, her students have trained 170 dogs.
"Can you imagine a classroom with 30 kids and 21 dogs that are less than one year old?" Hearn Said.
The dogs then move to certified (持有证书的) trainers who work for Guide Dogs for the Blind. After being trained for some time, they finally become real guide dogs. Guide Dogs for the Blind thinks highly of Hearn's and her students' work.
Hearn's work not only helps blind people, but also teaches her students the importance of giving back to society (社会).
