A sign can be found in the front yard of a house in the US. The people living here want to let their dog play outside and ensure it won’t run into the street. So, they hire a company to set up an “invisible fence”, an electric wire buried in the ground around the yard. The dog wears a special collar and when it walks near to the “fence”, the wire will send out a small shock. The dog quickly learns to stay away from the edge of the yard. As it says at the bottom of the sign, the fence will keep your dog “safe” (away from the street) and “at home” (contained inside the yard).
The small word “BRAND” printed in blue means that “Invisible Fence” is registered as the company’s brand name. Similarly, the “TM” printed after “your dog safe at home” stands for “trade mark”, a slogan registered specifically to one company.
1. The people set up an “invisible fence” _________.
A. to let their dog play outside their house
B. to keep their dog away from the edge of the yard
C. to keep their dog inside their yard
D. to warn others not to enter their house
2. Which is NOT true about the “invisible fence”?
A. The fence does not exist at all.
B. The “Invisible Fence” is the name of a company.
C. Without the special collar, the fence won’t work on the dog.
D. Science and technology play an important part in it.

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
