    Winter is cold and it can be difficult for animals to find food during winter. They get through winter in many ways.

Would you like to go to a warm place for the winter? That’s what migratory (迁徙的) animals do. When the weather starts to get cold, migratory animals like some birds and butterflies fly to a warmer place, and then they come back in spring.

Another good way to get through winter is to sleep through it. Many animals hide and sleep during the winter. Their body temperature drops and hearts beat more slowly. This helps them to save their energy. They do not eat. They live off their fat. They wake up when the weather gets warmer. We call this hibernation (冬眠). Snakes, frogs and bears hibernate in winter.

Many animals stay active in winter and adapt to (适应) the cold weather. Some animals save food in summer and autumn and eat it in winter. This is what squirrels do. Other animals make changes in their bodies or behavior (行为). To keep warm, some animals grow thicker coats in winter. Some animals eat different kinds of food as the seasons change. The red fox eats fruit and insects in the other three seasons, but eats small rodents (啮齿类动物) in winter. Other animals change colour. The arctic (北极的) fox is brown in summer. Its coat turns white in winter.

How do you live through the winter? Do you wear a thick coat? Do you stay inside? Or do you live in a warm place?
