It is hard for animals to find food during these cold days. They get through the hard time in many ways. ②Some birds fly to other places. Many of them leave before winter comes. They travel to warm places and come back in spring. We call it migration (迁徙). It’s a good way for them to get away from the cold weather. ③Another good way to get through winter is sleeping.

When it gets cold, they stay indoors and hardly go out. ⑤Other animals have to live in the cold winter.
