无人机的用途很多，从保护人们免受疟疾危害到向偏远地区发送邮件，使用这种技术的新方法一直在研发中。本文介绍无人机的最新用途。

词汇：Technology 科技

Technology is developing by leaps and bounds. A gadget as small as a smartphone now has more processing power than rockets to the Moon once had. New tech brings many advantages, making our lives easier and opening up new opportunities. One piece of kit that’s been really taking off recently is the drone. This pilotless mini aircraft, originally developed for aerial photography and warfare, is now bringing us benefits closer to home. In the last few years, tech companies such as Amazon, Alphabet and Uber have promised us delivery drones – bringing goods to our doorsteps in a matter of minutes. Progress in developing them has, however, been slow.

技术正在突飞猛进地发展。一个智能手机那么小的设备现在的处理能力比登月火箭曾经拥有的还要强。新技术带来了许多优势，使我们的生活更容易，并开辟了新的机会。最近最流行的一种装备就是无人机。这种无人驾驶的微型飞机，最初是为航空摄影和战争而开发的，现在正在为我们带来更近的好处。过去几年，亚马逊(Amazon)、Alphabet和优步(Uber)等科技公司向我们承诺使用无人机送货——在几分钟内将货物送到我们家门口。然而，它们的开发进展缓慢。

Drones are helping to connect with and enhance the lives of people in remote locations. In the UK, the Royal Mail wants a fleet of 500 drones to help deliver the mail to far-flung communities. Windracers, the company developing the drones, say they can fly in fog and produce 30% fewer emissions than comparable piloted aircraft. And in Coventry in the UK, construction has started on an air hub, which will act as a base for police and delivery drones. Urban-Air Port Limited is working with car-maker Hyundai on the mini-airport, known as a skyport.

无人机有助于与偏远地区的人们联系并改善他们的生活。在英国，皇家邮政(Royal Mail)希望组建一支由500架无人机组成的舰队，帮助将邮件投递到偏远的社区。研发这种无人机的Windracers公司表示，这种无人机可以在雾中飞行，比同类有人驾驶的飞机减少30%的排放量。在英国考文垂，一个空中枢纽的建设已经开始，它将成为警察和快递无人机的基地。城市航空港口有限公司(Urban-Air Port Limited)正与汽车制造商现代汽车(Hyundai)合作建设这座小型机场，即空中港(skyport)。

Drones could also play a part in improving the health of millions of people. In Zanzibar, for example, they’re being used to spray wetlands against malaria. And writing for BBC Future website, Harriet Constable describes an incredible development project by the University of South Australia. The plan is for drones to eventually be able to survey populations for disease by reading the blood oxygen levels of humans from the air. They’ll also be able to scan for other vital signs, like coughing and a high temperature.

无人机还可以在改善数百万人的健康方面发挥作用。例如，在桑给巴尔，它们被用于喷洒湿地对抗疟疾。哈里特·康斯特布尔为BBC未来网站撰写文章，她描述了南澳大利亚大学一个令人难以置信的发展项目。该计划是让无人机最终能够通过从空气中读取人类的血氧水平来调查人群的疾病。他们还能扫描其他生命体征，比如咳嗽和高烧。

It seems the sky’s the limit for what drone technology can achieve. The only thing that sometimes keeps it grounded is regulation. Writing for the BBC, Jessica Brown says: “If our skies are to become as crowded as our streets, airspace rules need updating to prevent accidents.” There are also related problems, such as noise pollution.

看来无人机技术的极限是无限的。有时唯一能让它保持稳定的就是监管。杰西卡·布朗(Jessica Brown)在为BBC撰写的文章中说:“如果我们的天空变得像街道一样拥挤，空域规则就需要更新，以防止事故发生。”还有一些相关的问题，比如噪音污染。
