名词解释
完形填空

Animals do many different, amazing things to get through the winter. Some of them migrate(迁徙). They travel to other places where the weather is warmer or where they can find food.

Many birds migrate in autumn. Because the trip can be dangerous, some travel in large groups. For example, geese(鹅) fly in noisy, “V”-shaped groups. Other kinds of birds fly alone.

Some animals stay active in winter. They must ___①___ themselves when the weather changes. Many change their doing or their bodies. For example, snowshoe rabbits grow white fur to help them hide in the snow.

Food is hard to find in winter. Some animals, ____②____ mice, collect lots of food in autumn and store it to eat later. Some animals eat different kinds of food as the seasons change.

Some animals sleep for part or all of the winter. The animal’s body temperature drops, and its heartbeat and breathing slow down so it uses very little energy. In autumn, these animals get ready for winter by eating much more food than in summer and storing it as body fat. They use this fat to keep them alive while sleeping.

Every type of insect(昆虫) has its own life cycle and that is the way it grows and changes. Different insects spend the winter in different forms of their lives. Some insects also spend the winter without moving. Some insects spend the winter as pupae(蛹). Other insects die after laying eggs (卵)in autumn. ③The eggs change into new insects in spring and everything begins all over again。
