【題目】 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 customers 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.

【1】Which of the following descriptions about Scout is right?

A.They can be powered themselves.B.They are strong enough to carry big things.

C.They can run with their six wheels.D.They can avoid obstacles ahead.

【2】What about Scout is still confusing to common people?

A.How many deliveries it can do on a full charge.B.Whether it can climb stairs or open gates.

C.How it recognizes the right owner of the things.D.How long it will take to get it fully charged.

【3】What does the underlined phrase “prior to” in paragraph 4 mean?

A.due toB.afterC.in front ofD.before

【4】What is the author’s opinion about delivery robots according to the last paragraph?

A.They are not easily available.B.They have some limitations.

C.They will replace humans soon.D.They won’t be well accepted.

【答案】

【1】D

【2】A

【3】D

【4】B

【解析】

這是一篇新聞報(bào)道。文章主要介紹了為了解決送貨的最后一公里問題，機(jī)器人應(yīng)運(yùn)而生，許多商業(yè)巨頭正在這一領(lǐng)域加緊努力。同時(shí)介紹了機(jī)器人外觀，工作原理，以及還需要解決的問題。

【1】

細(xì)節(jié)理解題。根據(jù)第二段中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.可知這款由電池驅(qū)動的汽車以正常的步行速度行駛，經(jīng)過編程可以避開行人、動物和垃圾桶等意外障礙物。由此可知，D選項(xiàng)“它們可以避開前面的障礙”正確。故選D。

【2】

細(xì)節(jié)理解題。根據(jù)第四段中Also unclear is the number of deliveries Scout can complete before its battery needs to be recharged.可知同樣不清楚的是，在需要充電之前，Scout能完成多少次投遞。由此可知，普通人對Scout困惑的是Scout充滿電可以送多少次貨。故選A。

【3】

詞義猜測題。根據(jù)上文it most likely requires the customers to apply a unique code, texted to them以及劃線短語后文to unlock the store box可知Scout很可能要求顧客在送貨前，使用發(fā)送給他們的唯一代碼來解鎖商店的盒子。由此可知，劃線短語意思“在……之前”。A. due to因?yàn)�；B. after 在……之后；C. in front of在……前面；D. before在……之前。故選D。

【4】

推理判斷題。根據(jù)最后一段中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.可知然而，這些環(huán)保機(jī)器人不能爬樓梯或打開大門，這意味著它們只能接觸住在地面的消費(fèi)者。此外，如果顧客不在家，機(jī)器人不能把包裹放在門前。這些問題能否得到解決還有待觀察。由此可推知，作者對送貨機(jī)器人的看法是它們有一些局限性。故選B。

【題目】Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

What Your “Age” Says About You

Imagine, for a moment, that you had no birth certificate and your age was simply based on the way you feel inside. How old would you say you are?

Like your height or shoe size, the number of years that have passed since you first entered the world is an unchangeable fact. 【1】

Scientists are increasingly interested in this quality. They are finding that our “subjective age” may be essential for understanding the reasons why some people appear to be energetic as they grow old — while others fade.

【2】 It is now well accepted that people tend to mature as they get older, becoming less extroverted ( 外 向 的 ) and less open to new experiences. These personality changes are often considered more obvious in the people with older subjective ages.

However, those who feel younger than they really are also become more reliable and less neurotic ( 神 經(jīng) 質(zhì) 的 ) as they gain the wisdom that comes with greater life experience. But it doesn’t come at the cost of the energy and vigor of youth. It’s not true that having a lower subjective age leaves us frozen in a state of permanent immaturity.

Feeling younger than your years also seems to come with a lower risk of depression and greater mental wellbeing as we age. 【3】 Most people felt about eight years younger than their actual chronological age (實(shí)際年齡). But some felt they had aged — and the consequences were serious. Feeling between 8 and 13 years older than your actual age resulted in an 18-25% greater risk of death over the study periods, and greater disease burden — even when you control for other demographic ( 人 口 學(xué) 的 ) factors such as education, race or marital status.

【4】 However old you really are, it’s worth questioning whether any of those limitations are coming from the within.

A.It also means better physical health.

B.One of the most interesting aspects of the research has explored how subjective age interacts with our personality.

C.Some studies have explored the potential physical consequences of this difference.

D.These findings can give us all a view of the way our own brains and bodies endure the passing of time.

E.But everyday experience suggests that people often don’t experience ageing the same way.

F.Many researchers are now trying to study how this knowledge might help us live longer.

Not bringing medicine
