With low temperatures and less and less food, winter is an uncomfortable season for animals. Many animals enter hibernation to get through it.
Hibernation is when an animal goes into a state of being inactive for a long time. 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 enter 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 28°C may bring a lot of trouble and cause aches. Low temperatures can also make people easier to be ill. In fact, humans don't need to sleep through 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 and 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.

5. 题干问人类不冬眠的原因，定位原文第三段：“Our body is not designed for hibernation.”，直接对应选项C。A选项与原文“less and less food”矛盾；B选项原文未提及；D选项原文未说温度不够低，故排除A、B、D，选C。
6. 逐一核对选项：A选项与原文“We have found fire... help us keep away from the cold”矛盾；B选项原文是“Many animals enter hibernation”而非“All animals”；C选项对应第五段“For long-distance space travel, it's possible”，表述正确；D选项原文说冬眠让动物身体冷却、心跳变慢，与选项“warm and fast”矛盾，故选C。
7. 代词指代题，定位最后一段“Some scientists have treated that seriously”，that指代上文“Could humans hibernate in the future?”，即未来人类冬眠这件事，对应选项C，故选C。
8. 主旨大意题，全文围绕“人类是否可能冬眠”展开：从动物冬眠引入，讲人类不冬眠的原因，再探讨未来人类冬眠的可能性，对应选项A，故选A。
