It is always hard to get out of bed on a cold winter morning. As I try to get out of bed, I sometimes think, “How
nice
it would be if I were a bear! I would then sleep through the whole
winter
until the following spring.”
Bears start
preparing
for hibernation (冬眠) in early autumn. They eat up to 40 kg of food a day—almost three times as much food as they
usually
eat in summer. When winter arrives, bears have a
hard
time finding fruit or hunting animals. To get through the cold months, they fall into long periods of
sleep
in order to save their energy.
After
bears go into hibernation in winter, they do not eat or drink, and their
fat
in their bodies will be broken down to produce (产生) energy. During the winter, they
lose
15 to 20 per cent of the body weight. After the weather becomes
warm
, bears come out from their holes. They eat early spring plants and hunt small animals
for
food.
Do all bears hibernate? Well, polar bears don't. They are used to
living
in cold weather. Also, bears in zoos do not hibernate if they can
get
food from people in winter. However, this is
unhealthy
for these animals because it may cause them to become overweight. Most zoos now allow bears to hibernate. If you don't see the
bears
when you visit a zoo in winter, you should be happy for them. It possibly means that they are enjoying a healthy sleep.
