Question

A desert is a difficult place for animals to live, and some have unusual ways of making a living. The Texas lizard has a strange way to keep itself safe. When a predator(掠食動物) gets too close, blood goes out from the lizard's eyes. Then it breathes in much air to make its body look bigger. Another interesting desert animal is the javelina. To make a predator afraid and run away, the javelina bravely faces the animal. It makes a big noise with its teeth. It raises the hard hairs on its back to make itself look bigger. The javelina also gives off a strong smell as a warning when it is afraid. This smell is so strong that javelinas are also called "smelly pigs". Javelinas keep safe by staying close to their family, so there's a good chance they can make a predator change its mind!

You might think a rain forest would be easier to live in than a desert. After all, there's plenty of food and water in a rain forest. But that also means a lot of animals live there. Being able to climb trees is a useful skill in the rain forest. It allows an animal to keep away from predators. The sloth spends most of its life in the treetops. Its strong, curved claws(爪子) help it climb and hang upside down from branches. The sloth also moves very slowly. It does this so it's not noticed. The aye-aye lives only in the rain forest of Madagascar, near Africa. The aye-aye is a night animal. This helps it to stay safe from daytime predators. However, the number of the aye-aye keeps going down and they may die out. People have hunted it because they think it brings bad luck. Also, much of the rain forest in Madagascar has been cut down, which has destroyed the aye-aye's home. Today there are laws(法律) to keep people from killing it.
