問題詳情：

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.許多公司開發自主機器人的目的是什麼?一個個地分析選項,對於A、C和D這三個選項來說,全文都沒有提到,B選項中“last mile”最後一英里是個比喻,原意為完成長途跋涉的最後一段里程,被引申為完成一件事情的時候最後的而且是關鍵*的步驟,現在是指將家庭和辦公室連線到運營商網路和Internet的任何通訊連線。根據第一段的“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. ”許多公司都在將自主機器人作為配送過程的最後一個環節,從商店或當地配送中心到客戶,可以肯定為B選項。A、 最後的測試。B、所謂的最後一英里。C、 機器人的安全。D、交貨速度。 2.從第二段我們能推斷出偵察機是什麼樣的?從第二段的“Its powerful sensors can also detect the movement of a car backing out of a driveway.”它強大的感測器還可以檢測汽車從車道上倒車的運動。可以很快確定*為C。至於其他三個選項無法從該段體現出來。A、 它看起來很酷。B。它會相應地調整速度。C、 它的感測器起著關鍵的作用。D.它將很快得到廣泛的應用。 3.第4段中帶下劃線的“之前”是什麼意思?首先“prior to”本身就是“在……之前,居先”的意思,若不認識這個詞語,也可進行猜測,根據原文“texted to them prior to the delivery.",可以猜想到應該是在送貨前向他們傳送簡訊,A和C都有“ 在……前”的意思,但是C是形容方位,所以應該選擇A。A、 在……前,先於;B、在……後;C、在……前面;D、由於。 4.這段文字可能取自哪一段?全文講的是送貨機器人這一個新技術將會為人們和企業帶來的便利,所以可以排除其他選項,選擇C。A、 生物教科書;B健康雜誌;C、 一份報紙;D、一本旅遊手冊。
