2020年高考英语天津卷（第一次）阅读理解C逐句翻译

一、原文翻译

Transport has a lot to answer for when it comes to harming the planet.

交通运输对地球的危害很大。

While cars and trains are moving towards greener, electric power, emissions from air travel are expected to increase massively by 2050.

虽然汽车和火车正在朝着更环保、更电力的方向发展，但预计到2050年，航空旅行的排放量将大幅增加。

If we want big green sky solutions, we need blue sky thinking.

如果我们想要大的“绿色天空”解决方案，我们需要“蓝天思维”。

Fortunately, there’s plenty of that happening right now, particularly the short-haul flights powered by batteries.

幸运的是，现在有很多这样的事情发生，特别是由电池驱动的短途飞行。

Harbour Air is the largest seaplane airline in North America, flying 30,000 commercial flights in 40 seaplanes each year.

Harbour Air是北美最大的水上飞机航空公司，每年乘坐40架水上飞机飞行30000次商业航班。

Significantly, all Harbour Air routes last less than 30 minutes, making it perfectly fit for electric airplanes.

值得注意的是，港航的所有航线持续时间都不超过30分钟，非常适合电动飞机。

“As an airline, we’re currently in the process of turning all our planes into electric airplanes.”

“作为一家航空公司，我们目前正在将所有飞机变成电动飞机。”

Says CEO Greg Dougall.

首席执行官格雷格·杜格尔说。

To make this happen, the airline has partnered up with MagniX to create the world’s first commercial flight with an electric engine.

为了实现这一目标，该航空公司与MagniX合作，创造了世界上第一个使用电动引擎的商业航班。

Making the skies electric isn’t just good for the environment, it also makes sound financial sense: a small aircraft use $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.

使天空电动不仅对环境有益,它还健全的金融意义:一个小型飞机使用400美元传统燃料飞行100英里,而电动8 - 12美元同样的距离,这还没有考虑传统发动机的维护成本更高这一方面。

There’s also the added bonus that electric planes are just much more pleasant to fly in.

电动飞机还有一个额外的好处，那就是乘坐起来更舒服。

No loud engine noise, no smell of fuel, just environmentally friendly peace and quiet.

没有发动机噪音，没有燃油气味，只是环保和平和安静。

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.

虽然电子飞机行业已经取得了真正的进步，但技术上的挑战仍然是让每个人都脚踏实地。

A battery, even a lithium one, only provides 205 watt-hours per kilogram;

一个电池，即使是锂电池，每公斤也只能提供205瓦时;

compare this to liquid fuel, which has a specific energy of 11,890 watt-hours per kilogram.

相比之下，液体燃料的比能量为每公斤11,890瓦时。

Carrying adequate batteries, however , would make the plane too heavy to get off the ground.

然而，携带足够的电池会使飞机太重而无法离开地面。

In aircraft, where every bit of weight counts, this can’t just be ignored.

在飞机上，每一点重量都很重要，这一点不能被忽视。

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.

从天然气到电动汽车工业过渡已经取得了更容易，通过hybrids-vehicles由燃料和电力。

Many believe the same pattern could be followed in the air.

许多人认为同样的模式也可能在空中发生。

Fuel consumption could be reduced as electric component is switch on at key parts of the journey, especially on take-off and landing.

在飞行的关键部位，特别是起飞和降落时，电子元件被打开，可以减少燃料消耗。

It’s certainly an exciting time for electric flying.

这无疑是一个令人兴奋的电子飞行的时代。

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.

随着海港航空(Harbour Air)等公司的引领，电池驱动的飞机，尤其是短途飞行，将在未来几年成为现实。
