With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the final leg of the delivery process, from the store or local distribution center to the customer. The latest to join the trend is e-commerce giant Amazon. Following a successful eight-month test run in Snohomish County, Washington, the company’s Scout robots have been making the rounds of Irvine, California, since August 6, 2019.

The six-wheeled Scout is about the size of a large cooler with the capacity to carry small or medium-sized packages. The battery-powered vehicle, which moves at a regular walking pace, has been programmed to avoid pedestrians, animals, and unexpected obstacles, such as garbage cans. Its powerful sensors can also detect the movement of a car backing out of a driveway.

To accelerate Scout’s development and bring it nationwide sooner, the company has created several detailed virtual maps of American suburbs and conducted trial deliveries to homes there.

Though Amazon has not shown how Scout ensures the delivery is picked up by the right person, it most likely requires the customer to apply a unique code, texted to them prior to the delivery, to unlock the store box. Also unclear is the number of deliveries Scout can complete before its battery needs to be recharged. Though the initial tests are being conducted with a human for company, the robot will be autonomous in the future. Its location, however, will be tracked at all times-if someone attempts to steal Scout, Amazon employees will be instantly sensed.

However, the eco-friendly robots are unable to climb stairs or open gates, which means that they can only reach consumers who live on the ground level. Additionally, the robots are unable to leave packages at the front door if the customers are not home. Whether these problems get resolved remains to be seen. For now, it appears that humans will still be needed to achieve the ever-growing demand for home and office deliveries.

are many companies developing autonomous robots for?

l tests.                                                   so-called last mile.

ts’ safety.                                             very speed.

can we infer about Scout from paragraph 2?

looks like a cooler.                                    adjusts its speed accordingly.

sensors play a key role.                             will be widely used soon.

does the underlined phrase "prior to" in paragraph 4 mean?

re                      r                         front of                 to

which is the text probably taken ?

A.A biology textbook.                                      B.A health magazine.

C.A newspaper.                                               D.A travel brochure.

【回答】

1.B; 2.C; 3.A; 4.C 解析：1.许多公司开发自主机器人的目的是什么?一个个地分析选项,对于A、C和D这三个选项来说,全文都没有提到,B选项中“last mile”最后一英里是个比喻,原意为完成长途跋涉的最后一段里程,被引申为完成一件事情的时候最后的而且是关键*的步骤,现在是指将家庭和办公室连接到运营商网络和Internet的任何通信连接。根据第一段的“many companies are turning to autonomous robots for the final leg of the delivery process, from the store or local distribution center to the customer. ”许多公司都在将自主机器人作为配送过程的最后一个环节,从商店或当地配送中心到客户,可以肯定为B选项。A、 最后的测试。B、所谓的最后一英里。C、 机器人的安全。D、交货速度。 2.从第二段我们能推断出侦察机是什么样的?从第二段的“Its powerful sensors can also detect the movement of a car backing out of a driveway.”它强大的传感器还可以检测汽车从车道上倒车的运动。可以很快确定*为C。至于其他三个选项无法从该段体现出来。A、 它看起来很酷。B。它会相应地调整速度。C、 它的传感器起着关键的作用。D.它将很快得到广泛的应用。 3.第4段中带下划线的“之前”是什么意思?首先“prior to”本身就是“在……之前,居先”的意思,若不认识这个词语,也可进行猜测,根据原文“texted to them prior to the delivery.",可以猜想到应该是在送货前向他们发送短信,A和C都有“ 在……前”的意思,但是C是形容方位,所以应该选择A。A、 在……前,先于;B、在……后;C、在……前面;D、由于。 4.这段文字可能取自哪一段?全文讲的是送货机器人这一个新技术将会为人们和企业带来的便利,所以可以排除其他选项,选择C。A、 生物教科书;B健康杂志;C、 一份报纸;D、一本旅游手册。
