Reversal—change your perspective and solve your problem

It’s often your definition of a problem that limits you in finding a suitable solution. Creative solutions require a change of perspective. 1

The reversal technique is a creative thinking technique that is based on the thought that to change your perspective, you sometimes need to change the order of the words in your problem definition.

How you change the order of the words doesn’t matter much, as long as the key words are reversed. 2 Your challenge is “How do we make sure that fewer people take cars to their work?”. Swapping the key words, you could rephrase this challenge as “How do we make sure that fewer cars take people to their work?”  In this case, the first statement will make you think of alternative means of transportation, like trains or bikes, while the second statement will probably make you think of solutions like carpooling—fewer cars for the same number of people.

Not every problem statement is suitable for a reversal. Sometimes using this technique requires you to first rephrase the question altogether. 3 For instance, the question “how might we sell more washing machines?” is not easily reversed—there is no key word to swap with “washing machines”. Yet, when you rephrase the question to “How might we sell more washing machines to young parents?” you can easily change it to “How might we sell more young parents to washing machines? 4 You could interpret this last sentence as “the washing machine pays the young parents to try it out”. Then, you could start communicating to potential buyers how much they will save each year when they choose your energy efficient washing machine.

As this example shows, some reversals will require a very flexible way of thinking. 5 However, thinking about the tiny amount of time it will “cost” you to try out a reversal, you have very little to lose and, potentially, lots to gain.

A The second problem statement is much more logical.

B Often it helps to add one more key word to the sentence.

C Rephrasing your challenge is to change the problem statement.

D A great way to do this is by “reversing” your problem statement.

E.For instance, imagine you are responsible for limiting the traffic jam in your area.

F.Admittedly, it is a very unusual challenge, but it might just stimulate a creative thought.

G.Not everyone will be able to move from an unreasonable statement to a useful solution.

5 G

【分析】

本文是一篇说明文。文章通过举例子介绍了一种解决问题的思维方式 —— 逆向思维,描述了它的好处和表现形式。

1 .根据上文 “Creative solutions require a change of perspective. (创造性的解决方案需要改变观点。) 以及下文 “The reversal technique is a creative thinking technique (逆向技术是一种创造性思维技术) 可猜测,划线句写的是创造性的解决方案是逆向技术。 D 选项 “A great way to do this is by “reversing” your problem statement.” (一个很好的方法是 颠倒 你的问题陈述。)符合题意,故选 D 项。

2 .根据上文 “How you change the order of the words doesn’t matter much, as long as the key words are reversed. (你如何改变单词的顺序并不重要,只要关键字颠倒过来就行。) 以及下文 “Your challenge is “How do we make sure that fewer people take cars to their work?”. Swapping the key words, you could rephrase this challenge as “How do we make sure that fewer cars take people to their work?””. (你面临的挑战是 我们如何确保开车上班的人更少 ?” 换掉关键词,你可以把这个挑战重新表述为 我们如何确保更少的车载着人们去上班 ?” 可知,本段是在举关键字颠倒过来的例子,并且有关于道路交通。 E 选项 “For instance, imagine you are responsible for limiting the traffic jam in your area.” (例如,设想你要负责限制你所在地区的交通堵塞。)符合题意,故选 E 项。

3 .根据前文 “Sometimes using this technique requires you to first rephrase the question altogether. (有时使用这个技巧需要你首先重新表达问题。) 以及下文 “For instance, the question “how might we sell more washing machines?” is not easily reversed—there is no key word to swap with “washing machines”. (例如, 我们如何才能卖出更多的洗衣机 ?” 没有一个关键词可以和 洗衣机 互换。) 可知,重新表达问题与关键词有关。 B 选项 “Often it helps to add one more key word to the sentence.” (通常,在句子中再加一个关键词是有帮助的。)符合题意,故选 B 项。

4 .根据前文 “Yet, when you rephrase the question to “How might we sell more washing machines to young parents?” you can easily change it to “How might we sell more young parents to washing machines? (然而,当你把这个问题重新表述为 我们如何才能向年轻的父母出售更多洗衣机 ?” 你可以很容易地把它改成 我们如何才能让更多的年轻父母喜欢洗衣机 ?” 可知,这种办法可以激发创造性思维。 F 选项 “Admittedly, it is a very unusual challenge, but it might just stimulate a creative thought.” (诚然,这是一个非常不寻常的挑战,但它可能会激发创造性思维。)符合题意,故选 F 项。

5 .根据前文 “As this example shows, some reversals will require a very flexible way of thinking. (正如这个例子所示,一些反转将需要非常灵活的思维方式。) 以及后文 “However, thinking about the tiny amount of time it will “cost” you to try out a reversal, you have very little to lose and, potentially, lots to gain. (然而,考虑一下你尝试逆转的时间 成本 ,你不会损失什么,但潜在地,你会得到很多。) 可猜测,做出这些反转很困难,要耗脑力。 G 选项 “Not everyone will be able to move from an unreasonable statement to a useful solution.” (不是每个人都能从一个不合理的陈述变成一个有用的解决方案。)符合题意,故选 G 项。

We’ve all been there. You’re around new people and you just want to impress them. It can be easy to pretend you know about movies, politics, or science just to get through an awkward situation. But contrary to what feels most natural, a new series of five studies from Pepperdine University shows that those who can admit when they don’t know something tend to actually have more knowledge. If you want to make those people think you’re smart, maybe the best thing to say is “I don’t know.”

For the study, which was led by Elizabeth Krumrei-Mancuso, the team of researchers had one question: Is there a knowledge benefit to admitting intellectual fallibility? To find out, they ran not one, not two, but five separate experiments. They engaged nearly 1,200 participants in their study, and evaluated them using a number of questionnaires testing their cognitive abilities, measuring their own predictions of their cognitive abilities, and, of course, rating their levels of intellectual humility.

For that last part, they used different methods in different studies to get a more wellrounded set of results. One IH survey used eight questions to assess participants on two elements: the “KnowingItAll” subscale, which judged their attitudes of intellectual superiority, and the “Intellectual Openness” subscale, which assessed how open they were to learning from others. In other studies, they used the 22-question “Comprehensive Intellectual Humility Scale,” which assesses participants on four elements: independence of intellect and ego, openness to revising one’s viewpoint, respect for others’ viewpoints, and lack of intellectual overconfidence. The five studies were used to examine past learning, thinking styles, traits, and motivations.

What the researchers may agree is that the best thing to remember is that curiosity seems to be a good thing. The world is big, and it’s impossible to know everything. At your next dinner party, ask questions and admit your own cluelessness. It might make you a little less clueless next time.

38Why did Elizabeth Krumrei-Mancuso led the study    

Ato find out whether admitting that you don’t know something is beneficial.

Bto find the certain benefit of admitting intellectual disability.

Cto compare the modest people with proud people.

Dto stress the importance of curiosity.

39From the article, we can learn that     .

Awe all tend to pretend we have a good command of knowledge.

Bthe study engaged over 1,200 participants in their study.

C”I don’t know” may be a good answer to people who ask you if you are clever.

Da number of questionnaires are used to test participants’ cognitive humility.

40What is the best title of the article    

ABe yourself!                                              BAdmitting your fallibility!

CExpress your drawbacks!                            DLet curiosity lead you!

  A native of Florida, U. S. , Hannah Herbst, 17, uses water power to deal with energy poverty. Herbst has risen to fame with the development of BEACON, an ocean energy probe that seeks to offer a stable power source to developing countries by using untapped energy from ocean currents.

She told Teen Vogue , " I was really involved in theater and athletics and I'm still really into those things. When I was in the seventh grade, I was put into a summer camp. The minute I got there I realized that I was the only girl in the program. I wanted to quit at that moment. But my dad told me, ' Just try it. '  I tried it for that day and it changed my life. ”

“At the camp, we started building the robots, which is something I had never done before but many of the boys had, and I realized it was a platform for problem-solving. We were solving simple tasks like how to push a robot off a platform. Learning from my partners as well as online articles about how to program and build was really interesting to me," said Herbst.

Later that year, she received a letter from her pen pal, Ruth, who lives in Ethiopia, and learned that she was living in energy poverty with minimal access to electricity and medical supplies. " I knew that I wanted to do something to help, so I created BEACON, she said.

The device is made from 90% recycled materials easily found throughout the world, including 2-liter bottles and recycled spoons. It costs $ 12 to make and can produce enough electricity to power an LED light. Hannah imagines BEACON being used in developing countries to power pumps for fresh water and she is working on polishing it to get it available to people all over the world.

  Chinese social media apps have struggled to win over users beyond their home. TikTok is changing that. In the space of just two years, the app has attracted more than half a billion users — around 40% of them outside China --who share short videos of themselves singing, cooking, dancing or just being silly.

Created by the Beijing-based Internet technology company Byte Dance, TikTok has gained an international edge over China's influential social media platforms, such as Tencent's WeChat, Sina Weibo (WB) and Youku of Alibaba (BABA).

What makes Byte Dance better is its right direction and achievement in the social media category, which is largely controlled by Facebook ( FB) , Twitter and Snap all Western companies, said Randy Nelson , head of Mobile Insights at analytics firm Sensor Tower. Social video apps reached new levels of popularity this year. Three of them are in the top 10 most downloaded apps worldwide, according to Sensor Tower. Byte Dance owns two of the three: Vigo Video and TikTok. The other is Instagram, which belongs to Facebook.

Byte Dance calls itself an artificial intelligence company. It uses machine learning   and algorithms to figure out what people like and give them more of what they want to see. the company is best known in China for the popular news app Toutiao, which was put into use in 2012. People got hooked on the app' s customized news feeds quickly. Toutiao now has more than 240 million monthly active users that spend on average 74 minutes per day on the platform.

Byte Dance' s success is attracting big investors. It's reportedly in talks with technology kingmaker SoftBank ( SFTBY) about an investment that would value it at around $75 billion, a huge jump from the $ 20 billion valuation it secured last year. That would make Byte Dance one of the world’s most valuable companies alongside Uber.

8What can be learnt about TikTok?

AIt has appealed to many foreign users.

BIt's the most popular Chinese app abroad.

CIt's the most successful app of Byte Dance.

DIt allows users to share whatever they like on it.

9What sets Byte Dance apart from other Internet technology companies overseas?

ASupport from its investors.                         BSuccess in social video apps.

CGreater diversity in contents.                       DAI technology applied to apps.

10Which of the following can replace the underlined words "got hooked on” in Paragraph 4?

Awere tired of                                             Bwere trapped in.

Cwere familiar with                                     Dwere attracted by

11What is the main idea of the text?

ATik Tok has beaten other social media apps.

BChina's social media apps are successful globally.

CSocial video apps win popularity around the world.

DByte Dance is taking the social media world by storm.

    Plastic-Eating Worms

Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.

Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes () from the worms’ stomachs. Their findings were published in Current Biology in 2017.

Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. "Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, "she explains, "The wax worm evolved a method or system to break this bond. "

Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?

Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply "millions of worms thrown on top of the plastic."

43What can we learn about the worms in the study?

AThey take plastics as their everyday food.

BThey are newly evolved creatures.

CThey can consume plastics.

DThey wind up in landfills.

44According to Jennifer DeBruyn, the next step of the study is to            .

Aidentify other means of the breakdown

Bfind out the source of the enzyme

Cconfirm the research findings

Dincrease the breakdown speed

45It can be inferred from the last paragraph that the chemical might            .

Ahelp to raise worms

Bhelp make plastic bags

Cbe used to clean the oceans

Dbe produced in factories in future

46What is the main purpose of the passage?

ATo explain a study method on worms.

BTo introduce the diet of a special worm.

CTo present a way to break down plastics.

DTo propose new means to keep eco-balance.

    Preparing Cities for Robot Cars

The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.

A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

47According to the author, attention should be paid to how driverless cars can __________.

Ahelp deal with transportation-related problems

Bprovide better services to customers

Ccause damage to our environment

Dmake some people lose jobs

48As for driverless cars, what is the author’s major concern?

ASafety.                                                      BSide effects.

CAffordability.                                            DManagement.

49What does the underlined word "fielded" in Paragraph 4 probably mean?

AEmployed.                                                BReplaced.

CShared.                                                     DReduced.

50What is the author’s attitude to the future of self-driving cars?

ADoubtful.                                                  BPositive.

CDisapproving.                                            DSympathetic.
