2020年無人機會搶走哪些工作
Google and Amazon were quick to put drones to use delivering orders.
谷歌和亞馬遜已經開始用無人機送貨，反應神速。
But new research suggests delivery is just one small way drones are going to replace humans. The tiny airborne vessels will soon clean windows on skyscrapers, verify insurance claims and spray pesticide on crops.
但最新調查顯示，快遞運輸只是無人機將要取代人類工作的領域之一。看似瘦小的無人機很快就可以給高樓擦玻璃；覈實保險索賠，還可能給農作物施肥。
The global market for drones, valued at around $2 billion today, will replace up to $127 billion worth of business services and human labour over the next four years, according to a new research by consulting firm PwC.
普華永道諮詢公司最新發布調查報告預計，無人機的全球市場價值如今已接近20億美元，到2020年，無人機將取代價值高達1270億美元（約合8271億元人民幣）的商業服務和人工勞務工作。
Drone technology could soon become part of our everyday lives, monitoring problems with crumbling infrastructure such as cracks in tarmac, bridges and houses and even repairing them as part of $45.2 billion of infrastructure work currently done by humans.
無人機科技將很快融入我們的日常生活，監測有裂痕的基礎設施的問題，比如柏油路面、橋樑和住宅的裂縫，甚至進行修復工作，進軍價值452億美元的基礎設施市場，而目前這一領域基本是人工勞動。
Construction companies, amid other things, will be able to attach 3D printers to drones to produce on site-replacement parts for damaged elements of houses or roads.
建築公司以及其它機構，未來能夠將3D打印機安裝在無人機上，爲住宅或道路現場生成替換部件。
Drones will be able to perform most tasks at height, reducing the risk of death and injury and increasing efficiency.
大多數高空作業都適合用無人機，以減少工傷並提高效率。
In transport, one of the most promising uses of drones is predicted to be food delivery.
在運輸行業，無人機最有可能“大顯身手”的領域是食品速遞。
“Providing products such as frozen food, ready-to-eat dishes or even daily groceries from large chains may become be the next big thing in the food and restaurant industries,” analysts at PwC said.
普華永道分析師認爲，“食品餐飲行業下一步可能着眼於用無人機運輸速凍食品、即食食品，甚至大型連鎖店的日用品。”
As soon as regulation permits, drones will be able to decrease the time it takes to deliver food, PwC said.
普華永道稱，只要規則允許，無人機就可以縮短運送食品的時間。
Google is for instance already trying to solve the problem of how to fly drones safely in yards without endangering pets or other potential obstacles.
比如，谷歌公司已經開始着手解決無人機如何安全飛過人們的院子，不威脅到寵物，也不撞到其他潛在的障礙物。
In agriculture, drones will increasingly be used to gather and analyse data on crops quickly as well as to do precise spraying on plants.
在農業方面，無人機將被更多地用於迅速收集、分析農作物數據，並精確噴灑。
