It looks like a small dragon with a long tail and four thin legs. What makes it special is its ability to regrow lost body parts. If it loses a leg, a tail, or even part of its heart, it can grow a new one in a few weeks. Unlike most amphibians, axolotls never grow into adults. They stay in their larval (幼虫的) form all their lives and live in water forever. Pangolin (Scaly Anteater) Pangolins are found in Africa and Asia. They have hard scales (鳞片) covering their whole body, which protect them from enemies. When they feel in danger, they roll themselves into a tight ball that even lions can't open. Pangolins eat ants and termites. They use their long, sticky tongues to catch insects from holes. Sadly, pangolins are now one of the most endangered animals because people hunt them for their scales and meat. ( ) 21. Where do axolotls live? A. In rivers in Africa. B. In lakes near Mexico City.

They can regrow lost body parts. D. They can live over 100 years. ( ) 23. What do pangolins eat? A. Small fish. B. Ants and termites. C. Bamboo leaves. D. Fruits and vegetables. ( ) 24. Why do pangolins roll into a ball when in danger? A. To keep warm. B. To look for food. C. To protect themselves. D. To play with other animals. ( ) 25. Why are pangolins endangered? A. Because they have no food to eat. B. Because their living areas are destroyed. C. Because people hunt them for scales and meat. D.
