Wouldn't it be funny if your mom said to you,"It's time for bed,honey.It's almost November!"Well,if you were a baby bear,your mother would be getting you ready to go into a deep sleep around October.
Bears in cold places go into hibernation to survive(存活) the winter.By taking this long sleep,they can get through the cold and snowy months when the food,1ike berries and nuts,cannot be found easily.
Have you ever heard someone say that they are as hungry as a bear?Bears need to eat a lot of food before hibernating.They eat so much that they may put on forty pounds of fat in a week.
During the winter,bears will 1ive off the fat stored in their bodies.Their bodies use a lot less energy during hibernation.That is because their hearts slow down.Their breathing slows down,too.Their bodies don't grow,and their body temperature drops.
If you were going to sleep all winter,wouldn't you want to be in a safe and protected place?That is what a bear wants,so it looks for a cave or a hollow (中空的) tree.It also makes a bed using grass and leaves.The bear may start to hibernate as early as October and might not wake up until April or May,when the weather is warm again.
When the bear wakes up,it will have lost much of his fat,but spring will bring a flesh supply of berries and nuts to enjoy until it is time to hibernate again in the fall.
