听力原文： Goats always seem to be second best to other farm animals. They give milk, but not as much as cows do. They offer meat, but not as much as pigs do. They provide wool, but not as much as sheep do. They carry loads, but not as well as homes do. However, goats have their own special merits. They thrive on weeds and twigs that would make cattle and sheep sick. They can live just about any-where since they need very little space. Years ago, city inhabitants even raised goats in their backyard. Goats can also climb just about anything, and are so sure-footed that they can even live on the slopes of mountains. In fact, the animal seems healthiest and happiest when there is something for them to climb. Because of their adaptability, goats are raised for their milk, meat, hair and leather in many parts of the world.
