It's late at night, the weather is bad, and you're hungry. Your favourite restaurant is less than a mile away, but you don't want to pay a $5 delivery (递送) fee. So, what do you do? Back in the old days, you would have braved the weather. But those days are coming to an end, at least in Washington.
A group of about 20 knee-high robots recently has come out on the sidewalks (人行道) of the nation's capital. Their tasks are to bring take-out food from restaurants to hungry customers at home while keeping the delivery cost to around a dollar.
The robots are European, created in Estonia by a company called Starship Technologies. Each of them is a middle-sized cooler on six wheels, and drives at an average (平均的) speed of about 4 miles per hour, about the speed of a walker. It has lights and a tall, bright orange flag so that it can be noticed by people on the sidewalk.
Here in Washington, Starship has teamed up with Postmates, the online delivery service, and the robots already are completing deliveries around the city. They move almost silently. They are electric, so there isn't much sound, except for their wheels. Their cameras recognize a lot-including traffic lights and stop signs.
The robots have only been in Washington for about a month, and they're still causing quite a stir (轰动), often getting stopped for photos. A young mother Maria Garcia is on the sidewalk, pointing out the robot to her daughter. "It's super cool," she says, "But the only thing that makes me worry about-is it going to put people out of jobs?
The company does not see robots as a replacement (代替), says Russell Cook, the director of Postmates. "We have people that drive cars, walk, and bike, and we see robots as another type of vehicle that helps us to offer deliveries," he says.
1.What does the underlined word "It" refer to?
A.The walker. B.The robot. C.The company. D.The car.
2.What do we know about the robots mentioned in the passage?
A.They were developed by a US company. B.They are able to travel at a high speed.
C.They create little noise while working. D.They can communicate with walkers.
3.What is the mother's worry about the robots?
A.They may not be as safe as expected. B.They may cause a stir on the sidewalk.
C.They may be destroyed by some people. D.They may take the place of deliverymen.
4.What is the text mainly about?
A.A leading online delivery company. B.Delivery robots in Washington, D. C..
C.The recent development of Postmates. D.People's growing worry about robots.
