专题一 第3讲 模拟练 提考能 A (2024·河北省金科大联考高三一模) Anyone eager to view from high the cityscapes of Guangdong, a province in southern China, may soon be able to do so from the cabin of a flying taxi.On October 13th the Civil Aviation Administration of China (CAAC)awarded a “type certificate”， a crucial piece of aviation paperwork, to the world's first electric vertical take-off and landing (eVTOL) taxi.And in case that does not sound futuristic enough, the small two-seater, called the EH216-S, was also cleared to fly without a pilot on board. The EH216-S is made by EHang, a company based in Guangdong.It looks like a scaled-up consumer drone (无人机) with a passenger bubble mounted on top.Propulsion (动力) is provided by 16 small rotors (转子), mounted on the tips of eight arms that fold away when the vehicle is not in use, allowing it to park in small spaces. The CAAC gave its approval after EHang had conducted more than 40,000 test flights, including with volunteer passengers in 18 cities across China.It also subjected the EH216-S to structural analysis and crash tests, and checked its ability to keep flying if one of its rotors fails.Regulators also inspected the wireless network which EHang uses to link its flying taxis to a control centre on the ground.That allows backup pilots to land an aircraft by remote control if there is a problem. EHang says its pilotless eVTOLs will be quieter than helicopters, their closest cousins, and much cheaper to operate, thanks in part to the ability to swap (交换) out an expensive pilot, for a second paying passenger.Performance, though, will be limited, at least at first.The EH216-S has a range of about 30 km, and a speed of up to 130 kph.The firm thinks that doing away with pilots will make things safer too.A computer's attention never wavers (动摇)．And flying is, in many ways, much easier to automate than driving, for there are fewer obstacles and unexpected situations to navigate. EHang has ambitions beyond China, too.The firm's closest competitors are Volocopter, a German company, and a pair of Californian firms, Joby Aviation and Archer Aviation.All three are conducting test flights of piloted eVTOLs of various designs. 1．What does the underlined word “cleared” in Paragraph 1 probably mean？ A．Produced. B．Approved. C．Removed. D．Tested. 2．What is Paragraph 3 mainly about？ A．What features EH216-S possesses. B．How strict the standard of EHang is. C．What benefits pilotless eVTOLs have. D．How EH216-S gets its approval. 3．What can we infer from the last paragraph？ A．EVTOLs will definitely bring in a huge profit. B．EVTOLs are popular worldwide. C．EHang may face challenges in expanding future market. D．EHang will improve its design to defeat competitors. 4．Where is the text probably taken from？ A．An ad in a magazine. B．A review of a bestseller. C．A column in a newspaper. D．A chapter of a science book. 【语篇解读】 本文是一篇新闻报道。文章主要介绍了中国民用航空局为世 ... ...
