Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients. While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears. But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept. The research results showed that during a fivemonth hibernation the bears' body temperatures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals. The research project leader said,“If our research could help by showing how to reduce metabolic (新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernations.” Craig Heller, of Stanford University, who contributed to the study, added, “There has always been a thought that, if there is ever longdistance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis.” 文章大意:本文是一篇说明文,主要介绍了专家希望将阿拉斯加黑熊冬眠的方法运用到人类身上来帮助宇航员延长在太空的使命以及治疗重症病人。 1.We know from the text that ________.
