一、题文

在从边原志【题文】Zero-emission large passenger aircraft powered by hydrogen will be technically possible in five years, according to Airbus, but they will not enter service for at least a decade as the price of the fuel needs to come down.在从边原志在从边原志The prediction comes from Glenn Llewellyn, vice-president of zero-emissions technology at the pan-European plane-maker. He said that while Airbus planned to demonstrate hydrogen-powered aircraft in 2025, over the next 10 years, hydrogen won’t be more economical than the fossil fuel.在从边原志在从边原志For passengers to be flying genuinely emissions free aboard hydrogen-powered planes—which emit only water and heat — their fuel needs to come from hydrogen produced via renewable sources such as wind and solar, he added.在从边原志在从边原志In an interview ahead of the Bloomberg NEF London Summit, Mr. Llewellyn said, “We already see massive increases in the amount of renewable energy being produced across the world. Wind energy production has multiplied by two over the last five years and solar energy production has multiplied by four.”在从边原志在从边原志A further challenge is building up the ecosystem that hydrogen aircraft, along with other forms of transport, will need. 在从边原志在从边原志This在从边原志在从边原志 ranges from creating the fuel from electrolysis to split water into hydrogen and oxygen powered by renewable energy, to the actual transport of the gas and fueling systems for it at airports.在从边原志在从边原志However, Mr. Llewellyn predicted that there was enough interest in the sector to make this happen. He added, “There are a number of independent institutes that have mapped out how hydrogen costs can come down over the next decades. We see a 30pc reduction in renewable hydrogen costs in 2030 compared to where it is today, and a 50pc reduction in renewable hydrogen costs by 2050.”在从边原志【小题1】What can we know about the hydrogen-powered aircraft according to the passage?在从边原志在从边原志在从边原志A．It will be an unrealistic dream.在从边原志在从边原志B．The cost of its fuel keeps rising.在从边原志在从边原志在从边原志在从边原志C．It will be accessible within a decade.在从边原志在从边原志D．Renewable energy makes it environmentally friendly.在从边原志在从边原志在从边原志【小题2】What did Mr. Llewellyn say about renewable energy?在从边原志在从边原志在从边原志A．It gains growing popularity throughout the world.在从边原志在从边原志在从边原志在从边原志B．More wind energy has been produced than solar energy.在从边原志在从边原志在从边原志在从边原志C．Hydrogen can only be generated from wind and solar energy.在从边原志在从边原志在从边原志在从边原志D．Hydrogen will be cheaper than fossil fuel in the coming ten years.在从边原志在从边原志在从边原志【小题3】What does the underlined word “在从边原志this在从边原志” in paragraph 5 refer to?在从边原志在从边原志在从边原志A．Ecosystem在从边原志在从边原志B．Challenge在从边原志在从边原志C．Aircraft在从边原志在从边原志D．Prediction在从边原志在从边原志在从边原志【小题4】What is Mr. Llewellyn’s attitude towards the future of hydrogen-powered aircraft?在从边原志在从边原志在从边原志A．Objective在从边原志在从边原志B．Optimistic.在从边原志在从边原志C．Doubtful.在从边原志在从边原志D．Pessimistic在从边原志在从边原志在从边原志

三、分析

难军无实列放能流越万【解析】难军无实列放能流越万【分析】难军无实列放能流越万本文是说明文。文章主要介绍了零排放氢动力飞机的研发现状和未来，还说明了氢动力飞机的一些特性和优点以及仍然面临的挑战。难军无实列放能流越万【小题1】难军无实列放能流越万细节理解题。根据第三段“For passengers to be flying genuinely emissions free aboard hydrogen-powered planes—which emit only water and heat — their fuel needs to come from hydrogen produced via renewable sources such as wind and solar, he added.(他补充说，如果乘客乘坐的是真正免费排放的氢动力飞机——只排放水和热量，他们的燃料需要来自风能和太阳能等可再生资源产生的氢)”可知，氢动力飞机使用可再生能源，很环保。故选D。难军无实列放能流越万【小题2】难军无实列放能流越万推理判断题。根据第四段“In an interview ahead of the Bloomberg NEF London Summit, Mr. Llewellyn said, “We already see massive increases in the amount of renewable energy being produced across the world. Wind energy production has multiplied by two over the last five years and solar energy production has multiplied by four.”(在彭博新能源论坛伦敦峰会召开前的一次采访中，Llewellyn先生说：“我们已经看到世界各地可再生能源产量的大幅增长。风能产量在过去5年增加了2倍，太阳能产量增加了4倍。”)”根据Llewellyn的话，可推知可再生能源在全世界越来越受欢迎。故选A。难军无实列放能流越万【小题3】难军无实列放能流越万词义猜测题。根据画线词上文“A further challenge is building up the ecosystem that hydrogen aircraft, along with other forms of transport, will need.(另一个挑战是建立氢燃料飞机和其他交通工具所需要的生态系统)”可知，这一挑战包括从可再生能源为动力将水电解成氢和氧的氢燃料生产，到运输氢燃料的交通工具以及机场的燃料补给系统。即，画线词指的是“挑战”。故选B。难军无实列放能流越万【小题4】难军无实列放能流越万推理判断题。根据最后一段“However, Mr. Llewellyn predicted that there was enough interest in the sector to make this happen. He added, “There are a number of independent institutes that have mapped out how hydrogen costs can come down over the next decades. We see a 30pc reduction in renewable hydrogen costs in 2030 compared to where it is today, and a 50pc reduction in renewable hydrogen costs by 2050.”(不过，Llewellyn先生预计，业内对氢动力飞机的浓厚兴趣将助其实现。他补充说，“有许多独立的研究机构已经制定出如何在未来几十年降低氢成本的方案。我们预计，到2030年，可再生氢成本将比现在减少30%，到2050年，可再生氢成本将减少50%。”)”可推知，Llewellyn先生对氢动力飞机的未来持乐观态度。故选B。难军无实列放能流越万
