摘要
<正>白靴兔的毛在夏天是褐色的,在冬天是白色的。为什么会这样呢?Animals of the Arctic have different ways of staying safe.Each summer the snowshoe hare’s fur is brown. It is hard for enemies to see the hare, because the land of the Arctic is also brown.But in winter, it snows. The hare’s thick fur will change into white.The enemies still can’t see it. Why? Because the Arctic is also white!
