Ⅳ. 阅读理解
With low temperatures and less and less food, winter is an uncomfortable season for animals. Many animals go into hibernation(冬眠) to get through it.
Hibernation is a period when an animal goes into a state like a deep sleep for a long time to spend the winter. Animals hide away from their enemies. Hibernation makes the animals' bodies cool and slows their heartbeat to just a few times per minute for up to months at a time.
But why don't humans hibernate? Humans don't go into hibernation for many reasons. Our body is not designed for hibernation. Our ancestors were animals with no history of hibernating. For example, human waste is a huge problem for human hibernation. Animals are able to stop their waste. Unluckily, humans can't do this.
There are other problems. Body temperatures below 2.8 ℃ may bring a lot of trouble and cause pain. Cold temperatures can also make it easier for people to get ill. In fact, humans don't need to sleep all through the winter. We have found fire, clothes, shelter, hunting, and farming. These ways can help us keep away from the cold.
Could humans hibernate in the future? For long-distance space travel, it's possible. A journey to Mars would take around months at the moment. If we hope to visit another star system, even if we could travel at the speed of light, the journey would take years. Being able to hibernate would make such distances less boring for the astronauts(宇航员) and help to save energy.
Some scientists have treated that seriously. They started to do something on long-term hibernation as a way to make long-term space travel possible and easier.
