     During the cold winter days you may find it hard to wake up in the morning. It's warm and cozy

(舒适的) in your bed.

     In winter, many animals like to sleep, too. But their sleeps can be very long and deep. This kind of

sleep is called hibernation (冬眠). During this kind of sleep, their temperatures go down, and hearts beat

(跳动) slowly. They take very small breaths.

     Animals can hibernate for part or all of the winter. It's hard for them to find things to eat. When they

go to sleep, they don't need much food.

     Bears, hedgehogs (刺猬) and chipmunks (花栗鼠) go to sleep in their homes. Frogs and snakes

hibernate, too. Frogs move into the earth under water to keep themselves warm.

     Before they go to sleep, they eat a lot to get fat (脂肪). Some also keep food in their homes to eat later.

Bears are the biggest animals that hibernate. They often sleep in caves (山洞).

     Bears must eat a lot of things like nuts before going to sleep for a long time. They eat as much as 300

apples (that's the same as 60 hamburgers) each day for many weeks. They can eat for 20 hours in a day!

     Bears can go into a very deep sleep. It can last from three months to half a year. During that time they

do not eat, drink or go to the toilet. A mother bear can give birth to babies during her hibernation.

     Other animals sleep less. Sometimes they wake up to eat, or take a walk. Then they go to sleep again.
