 Snakes,hummingbirds (蜂鳥)and squirrels hibernate in winter because of a long,cold season of little food. Unlike the warm seasons of spring and summer that provide lots of food for these animals,the winter season only provides a cold,icy ground where there is little food.

What's more,the winter days are short while the hours in the dark night seem too long. Searching for food often leaves the stomachs of these animals empty because by the end of their search their bodies end up burning more calories (卡路里)than the animals which get back from the food when and if any is found. So instead of starving (挨餓)or freezing (受凍)to death,these animals decide to hibernate during the winter months.

Hibernation helps these animals survive in the hard time. By hibernating,an animal saves its calories. Hibernation is a way of lowering an animal's body temperature and slowing down its heartbeat in order to save energy (能量)during times of less food and cold weather.

Every animal hibernates in different ways. While squirrels can wake up every four days to eat and take a trip to the bathroom,black bears can stay inactive杯活躍的),for up to seven months with no food,water,or visits to the bathroom.

It is not easy to be a vet (獸醫(yī)).You never know when you will be called upon to take care of a sick animal. You also do not always know what kind of animal you will be asked to take care of or what you must do to help the sick animal.

Once,when some children were playing with a dog,they threw a ball into its mouth. The ball got stuck (卡住) in the dog's throat (喉昽)and the dog could not breathe. The dog would die if they did not remove the ball quickly. The dog's owner took the dog to a vet called Robert Smith. Mr. Smith put his hands on the dog's neck. He could feel the ball. He was not sure what to do. He pressed (>E) a little harder. The dog opened its mouth and the ball came flying out! No one was more surprised than Mr. Smith.

Another vet,Peter Brown,worked with sea animals. One day,he was called upon to take care of a dolphin. The dolphin had something in its mouth that had to be taken out,but it did not want to open its mouth. Nineteen men had to hold the strong and slippery (滑的)dolphin so that the vet could open its mouth.
