DAirline travel causes roughly 2%-3%of the pollution that makes the greenhouse effect worse.Airplanespowered by a very common gas called hydrogen()could change all of that.Last Thursday,a company calledZeroAvia made a successful test flight of what it calls the "largest hydrogen-powered aircraft in the world".Manycompanies are working on hydrogen-powered vehicles,but ZeroAvia's test flight used a plane that can seat 6people-the largest hydrogen-powered plane ever flown.ZeroAvia made a similar flight in June,but that one wasbattery-powered.Hydrogen can be used to power vehicles by combining it with oxygen in a "fuel cell",which is like a batterythat never runs out as long as it has hydrogen.The chemical reaction which takes place between hydrogen andoxygen in a fuel cell creates electricity,but doesn't give off any pollution-only water.Thursday's flight was animportant step in the company's HyFlyer project.The company is hoping to make it possible for airlines to carrysmall numbers of passengers for short distances without polluting.The company's next big goal is to make alonger flight-of about 465 kilometers or more-by the end of the year.ZeroAvia believes passengers couldactually be flying on hydrogen-powered airplanes by 2023.Another company called Gravity Industries put on a test of its jet suit recently to show how it could helpemergency medical workers reach injured people quickly.The jet suit is powered by small jets on each arm andone on the back.By pointing the jets at the ground,the pilot can take off.Returning to the ground is just a matterof pointing both arms out to the side.Richard Browning,the suit's inventor,flew up a mountain to find somepeople who were pretending to be hurt (for the test).To reach the spot by climbing the mountain would havetaken 25 minutes.Mr.Browning was able to cover the same distance in just 90 seconds.One problem?The cost.The suit sells for about 440,000.12.Compared with similar ones,what advantage does ZeroAvia's aircraft have?A.It has its own fuel cell.B.It flies faster and longer.C.It can be battery-powered.D.It can contain more people.13.What is ZeroAvia's opinion about its hydrogen-powered aircraft?A.It'll be more costly than ever.B.It'll be available for real soon.C.It'll rid the greenhouse effect.D.It'll get jet suits more popular.14.Which aspect of the jet suit does paragraph 3 mainly focus on?A.How it helps people land.B.How it was tested.C.How it was invented.D.How it saves people's lives.15.What is the suitable title for the text?A.New Flying Inventions Take OffB.Companies Develop New PlanesC.Flying Fuel Cells Are Used WidelyD.Jet Suits Are on ZeroAvia's Planes【语篇导读】本文是一篇科普说明文。文章介绍了两个与航空有关的新发明:没有污染的氢动力飞机和用于紧急医疗的喷气式飞行服。l2.D推理判断题。根据第一段的Many companies are working on hydrogen-powered vehicles,but ZeroAvia'stest flight used a plane that can seat6 people-the largest hydrogen-powered plane ever flown.可知,许多公司都在研发氢动力交通工具,但ZeroAvia的试飞使用了一架能坐6人的飞机,这是有史以来最大的氢动力飞机。13.B推理判断题。根据第二段最后两句可知,该公司的下一个大目标是在今年年底前实现更长的飞行距离一约465千米或更多。ZeroAvia公司相信,到2023年,乘客就可以真正乘坐氢动力飞机了。l4.D段落大意题。第三段主要谈了Gravity Industries公司最近对其喷气式飞行服进行了测试,以展示它如何帮助急救人员迅速接近受伤的人。其余选项本段有提到,但不是本段的主要内容。15.A标题归纳题。本文介绍了两种新型的与航空有关的发明物:一个是氢动力飞机,一个是喷气式飞行服。它们有各自的用途和特点。氢动力飞机可以避免污染,减少温室效应;喷气式飞行服可以在危急时刻迅速解救处于危险中的人。A项一语双关,take off有“起飞”之意,也有“成功”之意,恰恰能概括本文主题。
