高中英语外刊阅读语法填空December 81 Is human hibernation possible?人类为什么不冬眠？With low temperatures and a lack of food, winter is a harsh season for animals. Many animals enter hibernation 1 _ ( get) through it.Hibernation is when an animal goes into a state of extended inactivity. Animals hide away from predators(捕食者). Their metabolism（新陈代谢） will slow to less than a quarter of 2_(it) normal rate. This cools the creatures body and slows its heartbeat to just a few times per minute, for up to months at a time. But why dont humans hibernate? Human hibernation doesnt exist for many reasons. Our body is not 3_(design) for hibernation. Our evolutionary ancestors were tropical animals with no history of hibernating: Humans have only migrated into temperate(温带) and subarctic（亚北极） latitudes in the last hundred thousand years or so. Thats not quite long enough to evolve all the metabolic adaptations we would need to be able to hibernate, according 4_ the BBC Science Focus Magazine. For example, waste 5_(manage) is a huge challenge for human hibernation. Animals that hibernate are able to 6_(essential) stop their urination and defecation (排泄)during hibernation, sometimes through a process of reabsorption（重新吸收） to preserve nutrients. 7_(fortunately), humans cant do this. There are other challenges. Body temperatures below 2.8 C tend 8_(disrupt) the human digestive tract (消化道) and may cause pain. Cold temperatures can also suppress the immune system, making people more vulnerable （易受伤害的）to infections, according to Smithsonian Magazine. In fact, humans dont need to sleep through winter. We have discovered fire, clothes, shelter, hunting and agriculture, all of 9_ are much more effective ways of surviving the cold. Could humans hibernate in the future? For long-distance space travel, its 10_(like). A journey to Mars would take around months using current technology. 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 considerably less boring for the astronauts and conserve vital resources, according to University of Oxford in the UK.keys:1 to get 2 its 3 designed 4 to 5 management 6 essentially 7 Unfortunately 8 to disrupt 9 which 10 likely2 Chinas homegrown heroes顾诵芬、王大中获国家最高科技奖When China was still poor and far behind the West, two Chinese scientists insisted on 1_(lead) the world through homegrown innovation(自主创新). They are jet fighter designer Gu Songfen and nuclear energy scientist Wang Dazhong, 2_won Chinas top science award the State Preeminent Science and Technology Award（国家最高科学技术奖） on Nov 3. In the 1950s, China had no aviation(航空) experience, equipment or wind tunnels. As the head of the aerodynamics（空气动力学的） team in Shenyang, Gus first task was to develop the countrys first homegrown jet aircraft. Despite difficulties, he managed 3_(complete) JJ-1, the first jet aircraft 4_(design) in China. Gu, 91, started the aerodynamic design of aircraft, which advanced the 5_(develop) of a number of major jet fighters, 6_(include) the Nanchang CJ-6, a basic training plane, and the Shenyang J-8, a high-speed, high-altitude single-seat interceptor. Those aircraft not only 7_(great) improved Chinas air defense capabilities but also laid the foundation of its aviation industry. Wang Dazhong, 86, has spent 60 years 8_(work) to develop nuclear energy. After nuclear accidents in Three Mile Island(三英里岛) in the US in 1979, and Chernobyl in the Soviet Union in 1986, scientists all over the world have worked hard to ensure that reactors（反应堆） are made “inherently safe(固有安全)”. It means they do not rely 9_ countermeasures（对策） powered by external（外部的） resources to remain stable. As an academician(院士) at the Chinese Academy of Sciences, Wang led the research, design and operation of Chinas first five-megawatt low temperature nuclear heating reactor（5兆瓦低温核供热堆） and later of its 10-megawatt high temperature gas-cooled reactor. He used key technologies 10_(relate) to helium coolant（氦冷却剂）. Both reactors improved the inherent（固有的） safety of nuclear energy, as well as the application of clean energy. Wangs scientific achievements have paved the way for clean energy as China works to achieve carbon neutrality, said He Jiankun, an expert at Tsinghua University.keys:1 leading 2 who 3 to complete 4 designed 5 development 6 including 7 greatly 8 working 9 on 10 related3 Learning in Russia越来越多中国学生留学俄罗斯“With 1_(far) cooperation in trade and a close friendship between China and Russia, there are more students 2_(apply) for Russian universities,” Liu Jing told Sputnik News, a Russian news agency. Liu is 3_ undergraduate from Moscow State University (MSU). Indeed, Russia is now a desirable destination for Chinese international students. Their number has increased from about 15,000 in 2012 to 49,000 in 2019, according to Sputnik News. So what has led to such an increase? Why are students choosing 4_( study) there? Apart 5_positive bilateral relationships(双边关系), financial benefits and career prospects（职业前景） also factor into students deciding to apply for Russian universities. “One of the main 6_(advantage) of studying in Russia is its relatively 7_(cheap) tuition fees and living costs than in Europe or North America,” said Tian Tian, a graduate student from The Saint Petersburg State University of Aerospace Instrumentation. Generally, it takes about 60,000 to 100,000 yuan (covering tuition, accommodation and living fees) every year to study in universities 8_(locate) in major cities such as Moscow and St. Petersburg, according to JJL overseas education. “It is undoubtedly a great choice to study in Russia without spending too much money while enjoying world-class education,” said Alex Zhang, 9_ got his masters degree in Russian translation at MSU in 2019. “It not only made me more professional in Russian-Chinese translation but cultivated my social skills. That gave me an edge when hunting for a job,” Zhang added. He is now in a Chinese company working on international project management, which requires 10_(effect) communication with different partners.keys:1 further 2 applying 3 an 4 to study 5 from6 advantages 7 cheaper 8 located 9 who 10 effective
