It was Saturday morning. Kate got up early and had breakfast quickly. She was so excited. She was going to the zoo with her family today! There was a new kind of animal in the zoo. It was called sloth (树懒) and it was from South America. Kate never saw a sloth before. She could not wait to see it.

    When Kate and her family got to the zoo, there were already lots of people around the sloth. The sloth was staying in a tree! It looked so cute! Kate looked at the animal for about ten minutes, and then she asked, “Are you sure it is alive (活的), Dad? I don't see it moving at all.” “Of course it is alive,” her father said. “But a sloth can only move really slowly.”

    Kate's family went to see some other animals. Then they went back to the sloth after lunch. Kate looked at the sloth carefully. It was really at a different place, near the place where it stayed in the morning. “You are really lazy, Mr. Sloth,” Kate said. “I think you should do more exercise. It is good for your health.”
