The reality TV wildlife edition has just come to a dramatic end. The world watched as the bears packed on pounds before they went into their den (兽穴) for the winter. Over the next few months, Fat Bear Week winner, 435 Holly, will go into hibernation (冬眠). Why do bears do this?
The mysteries around hibernating bears have attracted curious researchers for ages. What is hibernation, and what causes it? And probably most interestingly — could humans do this someday?
Dr. Kelly Drew, who studies hibernation, is one of the scientists consulting on a project funded by NASA, looking to put humans into hibernation for spaceflight. “For sending people to space, I think our first step is to perfect short-term hibernation-like periods in humans,” she says. “If we can figure this out, we can then try for longer periods.” We still have a long way to go before this science fiction dream becomes a reality, but several scientists around the country have been studying hibernation.
Cory Williams, at the University of Alaska Fairbanks, says, “A huge variety of mammals (哺乳动物) hibernate. However, hibernation in bears is different from that in small mammals…their body temperature only drops a few degrees and they don’t experience periodic rewarming.” In general, mammals with lower body temperatures during hibernation awaken every few days to raise their body temperature, or eat a bit. Bears do not emerge for any of these activities. Instead, they live off the fat they have collected during the summer and autumn months and even recycle their metabolic (新陈代谢的) waste.
At the moment, the study of hibernation has and continues to contribute greatly to applications in the human world. For example, bears are able to maintain their bone mass during hibernation, and understanding this could help advance the study of treating people with weak bones. Perhaps one day, it will be the key to sending humans far off into space too.
1.Why is 435 Holly mentioned in Paragraph 1?
A.To show the popularity of Fat Bear Week. B.To introduce the topic of hibernation.

2.How do bears hibernate?
A.They produce new body fat.
B.They lower their body temperature greatly.
C.They sleep through the whole winter.
D.They rewarm themselves regularly.
3.What’s the last paragraph mainly about?
A.The new findings about hibernation. B.The significance of studying hibernation.
C.The ways bears maintain their bone mass. D.The barriers to sending humans into space.
4.What’s the best title for the text?
A.What could bears and astronauts have in common?
B.What effects does hibernation have on bears?
C.Why do bears need to go into hibernation?
D.How do humans and bears get along?

Most of the new diseases we humans have faced in the past several decades have come from animals. The more we come into contact with wild animals, the more we risk a so-called disease “spillover” from animals to humans.
“As people move and wildlife move in response to a changing environment, humans and wildlife and animals will come in contact more regularly,” said Jeanne Fair from the Los Alamos National Laboratory in New Mexico. Fair argues that by shifting animal habitats, climate change will also make the opportunities for disease spillover more frequent. “Everything is sort of shifting and will shift into the future as the environment changes through climate change,” Fair said.
Scientists, including climatologists and epidemiologists (流行病学家) on Fair’s team at Los Alamos, are beginning to model how changes to the climate will impact the spread of infectious diseases. It’s early days for this kind of research, but previous studies suggest that extreme weather has already played a role in at least one outbreak. Scientists say drought and deforestation have combined to force bats out of rain forests and into orchards (果园) in Malaysia to find food. Those bats, a common disease reservoir, then passed the Nipah virus through pigs to humans for the first time in the late 1990s.
“We’re going by the past data to really predict what’s going to happen in the future,” Fair said, “And so, anytime you increase that wildlife-human interface, that’s sort of an emerging disease hot spot. And so, that’s just increasing as we go forward.”
Jeffrey Shaman, head of the climate and health program at Columbia University’s public health school, argues we don’t yet know whether climate change will cause a net increase in infectious disease rates globally. For example, mosquitoes carry disease that affects millions of people across the world every year. As their habitats expand in some parts of the world, they might contract diseases elsewhere. Shaman says what we know for certain about climate change is that it will make it harder to predict where disease outbreaks will pop up.
1.How does climate change affect the spread of disease according to Fair?
A.By breaking animals’habits. B.By increasing animals’varieties.
C.By promoting animals’breeding. D.By changing animals’living environment.
2.What is the example of bats for in paragraph 3?
A.Explaining the influence of Nipah virus.
B.Proving the harm of bats to human beings.
C.Showing the effects of climate change on disease.
D.Presenting scientists’early study about the cause of disease.
3.What can we infer from Fair’s words in paragraph 4?
A.Humans should give up studying animals.
B.Frequent contact with animals can cause disease outbreaks.
C.Disease hot spots will disappear if animals die out.
D.Past data can solve the problems in the future.
4.What could be the best title for the text?
A.Climate Change and Disease Spillover
B.Animals’Interaction with Humans
C.Early Studies about Extreme Weather
D.Scientists’Prediction for Disease Outbreaks
