While travelling along the way
2020·天津5月高考·阅读理解C篇
Transport has a lot to answer for when it comes to harming the planet. While cars and trains are moving towards greener, electric power, emissions from air travel are expected to increase massively by 2050. If we want big green sky solutions, we need blue sky thinking. Fortunately, there's plenty of that happening right now, particularly the short-haul flights powered by batteries.
Harbour Air is the largest seaplane airline in North America, flying 30,000 commercial flights in 40 seaplanes each year. Significantly, all Harbour Air routes last less than 30 minutes, making it perfectly fit for electric engines. “As an airline, we're currently in the process of turning all our planes into electric airplanes，” says CEO Greg McDougall. To make this happen, the airline has partnered up with MagniX to create the world's first commercial flight with an electric engine.
Making the skies electric isn't just good for the environment, it also makes sound financial sense: a small aircraft uses $400 on conventional fuel for a 100-mile flight, while an electric one costs $8－12 for the same distance, and that's before you factor in the higher maintenance costs of a traditional engine. There's also the added bonus that electric planes are just much more pleasant to fly in. No loud engine noise, no smell of fuel, just environmentally friendly peace and quiet.
While there has been real progress in the e-plane industry, the technical challenges that remain are keeping everyone's feet firmly on the ground. A battery, even a lithium one, only provides 250 watt-hours per kilogram; compare this to liquid fuel, which has a specific energy of 11,890 watt-hours per kilogram. Carrying adequate batteries, however, would make the plane too heavy to get off the ground. In aircraft, where every bit of weight counts, this can't just be ignored.
The transition (过渡) from gas to electric in the automobile industry has been made easier by hybrids — vehicles powered by both fuel and electricity. Many believe the same pattern could be followed in the air. Fuel consumption could be reduced as the electric component is switched on at key parts of the journey, especially on take-off and landing.
It's certainly an exciting time for electric flying. With companies like Harbour Air taking the lead, battery-powered planes, especially on short-haul journeys, are set to become a reality in the next few years.　
[真题再做]
语篇解读：本文是一篇说明文。文章讲述了在空运中，尤其是在短途空运中使用电能作为能量来源的可能性、好处、存在的挑战以及解决办法。
1．According to Para.1, what is happening in air transport
A．New explorations of the sky are being launched.
B．Pollution caused by batteries is being controlled.
C．Efforts are being made to make air travel greener.
D．Demand for short-haul flights is increasing massively.
答案：C　
解析：细节理解题。根据第一段最后一句可知，幸运的是，人们正在构思解决空运产生的环境污染的方法，如由电池提供动力的短程航班，即现在人们正在努力让空中旅行变得更加环保。
2．Why is Harbour Air fit for electric flights
A．It runs short routes.
B．It has a strong partner.
C．Its planes can land on the sea.
D．It has planes with powerful engines.
答案：A　
解析：细节理解题。根据第二段第二句可知，Harbour Air适合使用电能提供动力的飞机的原因是它所有航线的航行时间都不超过30分钟，换句话说就是航线短。
3．The expression “added bonus” refers to the fact that electric planes .
A．give passengers more pleasant views
B．bring airlines more financial benefits
C．offer more enjoyable flying experiences
D．cost less in maintenance than traditional ones
答案：C　
解析：词义猜测题。根据画线词所在句可知，“that electric planes are just much more pleasant to fly in”是同位语从句，解释说明“added bonus”的内容，而电动飞机飞行时没有发动机的噪声，没有燃油的气味，只有安静，这使人们能够获得更加愉悦的飞行体验。
4．What might be the biggest challenge of electric flying
A．To improve the ground service for e-planes.
B．To find qualified technicians for the e-plane industry.
C．To calculate the energy needed to power e-planes.
D．To balance power and weight of batteries in e-planes.
答案：D　
解析：推理判断题。根据第四段最后两句可知，如果携带充足的电池，飞机就会过重而无法起飞，由此可知，平衡电池重量与电量是电力飞行面临的最大挑战。
5．What could be done during the transition from gas to electric in air flight
A．To produce new electric components.
B．To increase battery consumption.
C．To use mixed-power technology.
D．To expand the landing field.
答案：C　
解析：细节理解题。根据倒数第二段可知，许多人认为，燃料和电力同时供能这种模式，即混合型供能技术可以运用在空运中。
6．What is the author's attitude towards the prospect of electric flying
A．Short-sighted.　　　 B．Wait-and-see.
C．Optimistic. D．Skeptical.
答案：C　
解析：观点态度题。根据最后一段的内容可知，作者认为电力飞行，尤其是短途旅行中的电力飞行一定会在接下来的几年中成为现实。由此推知，作者对电力飞行持乐观态度。
