Lisa is a nice girl. On the weekend, she usually goes to the Animal Rescue (救助) Center to be a volunteer (志愿者). One day, she sees a cute dog in the Animal Rescue Center. Lisa always wants to keep a dog at home, so she takes the dog home. She calls her Puffy. Puffy is a blind (盲的) dog, but Lisa likes her very much. After Lisa goes home from school, Puffy likes to sleep on Lisa's legs. Then Lisa likes to sing for her. It's really a great time for them.

    Aunt Diana lives next to Lisa's home. She is a teacher and she also loves animals very much. One day, she sees a dog in her school and one of his legs is hurt (受伤的). She takes him home quickly. Lisa and Aunt Dianalook afterhim well. They make nice food for him, and take him to the animal hospital (医院). Aunt Diana calls their new friend Carl. Lisa thinks it sounds cool. Now Carl is well, and he likes playing with Puffy. They're good friends.
