If you live in southwest Virginia, don’t be surprised at the sight of a drone(无人机) winging its way, doing airborne delivery over your neighborhood.
On October 20,2019,wing,an American multinational company, began the most advanced trials of commercial drone delivery in Virginia. Residents can now use a smartphone app to order items from Wing partners such as Sugar Magnolia. A Wing drone never sets down at destinations, instead gently lowering the package with a rope outside the customer's door.
Though Wing is the first American company to receive Federal Aviation Administration(FAA)approval to use commercial drones as a widespread service. it is not the only one. On October 22,2019,multinational delivery company UPS, which had also received FAA approval for its drone fleet, announced it would soon begin trial deliveries of goods from health care company CVS. Meanwhile, ridesharing company, Uber, which had partnered with McDonald's, hoped to use its drones to deliver food to hungry customers in San Diego, CA, before the end of 2019. Amazon also plans on testing its trial deliveries of goods in a yet-to-be-determined location in the upcoming months.
Every company's drones can carry packages weighing up to five pounds, and the series of trial are hortative, but widespread drone delivery still has many challenges. These include basic issues like finding places for drones to land, reducing noise pollution, and even ensuring the drones don't run into each other while airborne.
To help sped up the process, NASA announced the Urban Air Mobility Grand Challenge. The competition challenges airspace service providers to find creative solutions to the issues, so that drone deliveries can become a reality soon. “We are moving fast,” said NASA Administrator Jim Bridenstine. “We want to see by 2028 at least one city--maybe more than one--have the ability to control hundreds of drone delivery systems. They could be carrying goods, doing thousands of missions every day.”
1.What can be inferred from the passage?
A.It's impossible to crash other drones during the delivery.
B.People can order items from Wing directly with an app.
C.More companies are expected to try out their drone delivery.
D.Drones deliver items by gently bringing them down to the ground.
2.What does the underlined part “hortative” in Paragraph 4 mean?
A.Encouraging. B.Relaxing.
C.Creative. D.Relative.
3.What's Jim Bridenstine's expectation of drone delivery?
A.To increase the speed of airborne delivery.
B.To see drone delivery systems widely used.
C.To be able to control the airline system.
D.To provide more solutions to goods delivery.
4.Which is the best title for the text?
A.The Future of Drone Delivery
B.How to Achieve Drone Delivery in 2028
C.The Advantages of Using Drone Delivery
D.Drone Delivery May Become a Reality in the US
