We call these places "habitats". Each habitat has what the animals need to live. Forest Animals Many animals live in forests. Monkeys live in trees. They eat fruits and leaves. Bears live in forests too. They sleep in caves during winter. This is called hibernation. Ocean Animals The ocean is home to many animals. Dolphins and whales live in the ocean. They can't breathe underwater, so they must come to the surface for air. Fish can breathe underwater through their gills. Desert Animals Deserts are very hot and dry. Camels are desert animals. They can go without water for a long time. Snakes and lizards live in deserts too. They stay in holes during the day when it's too hot. Polar Animals The Arctic and Antarctic are very cold. Polar bears live in the Arctic. They have thick fur to keep warm. Penguins live in the Antarctic. They have a layer of fat under their skin to stay warm. Animals are good at living in their homes. But when people destroy these habitats, animals lose their homes. We should protect all habitats. (A) 根据短文内容，选择正确答案 ( ) 38. Where do monkeys live? A. In caves. B. In trees. C. In holes. D. In water.
