Commuting to and from work can be a nightmare. Cars advance slowly in stop and go traffic, crawling from one traffic jam at stoplights to the next. At peak rush hour especially, there is no chance of sailing through a series of green lights. Now, thanks to artificial intelligence, German researchers have found a way to reduce time spent at the crossroads.
Called the KI4LSA project and funded by the Ministry of Transport and Digital Infrastructure, the innovation is being tested. Scientists first studied algorithms taken from a busy intersection to learn about traffic patterns and where improvements were most needed. Then, the technology, using high-resolution cameras and radar sensors, more precisely captured the actual traffic situation and detected the average speed of the cars and their waiting times. Finally, the AI uses deep enhanced learning algorithms to calculate the best switching behaviour for the traffic lights and determine the best phase sequence to shorten waiting times at the crossroads.
The results are encouraging when it is being tried out at a busy intersection in Lemgo, Germany. The intelligent lights are said to improve traffic flow by 10 to 15 percent, which results in money saved; the EU estimates that traffic jams create economic damage that adds up to 100 billion euros a year. Aside from reducing commuting time, these traffic lights will reduce noise and CO2 emissions from cars waiting at the crossroads.
Another exciting development in this research is the K14PED project, which studies pedestrians crossing the crossroads. Using AI as well as a 3D points cloud, researchers can identify how many people are waiting at a pedestrian crossing and whether some of the disabled or elder people will need extra time to cross the street. Such a needs-based system could reduce pedestrian waiting time by 30 percent, which could then decrease jaywalking (乱穿马路) by 25 percent.
Researchers are optimistic that it will be adopted by many countries after the tests in the German towns of Lemgo and Bielefeld. This technology is exciting news for pedestrians and drivers alike. It encourages safety, protects the environment, and may even give you more time to enjoy your morning coffee before heading off to work!

【推荐1】Thanks to high-speed rail, the travel time between major cities in China has already been reduced to only a few hours, making travel within China much more convenient, both for Chinese citizens and travelers from overseas. This convenience in turn should accelerate development within China, as the time and expense of long-distance transportation has been greatly lowered. Without doubt, it will also bring the people of the country closer together, and in time bring about deep social changes, the full nature of which no one can fully guess.
Now that China has gained skill and knowledge in high-speed rail, it is seeking to export its technology to other countries. Its first venture on the international market was the development of a new high-speed rail line connecting Istanbul with Turkey’s capital, Ankara, 530 kilometers away. This was followed by projects in Saudi Arabia, Hungary and Serbia, Thailand, and Indonesia, among other countries. Perhaps its most ambitious project is a Trans-Asian network linking China with Europe, which is hoped to be completed by 2030 as a part of China’s Belt and Road Initiative. Already, China has agreed to build a 762-kilometer high-speed rail line in Russia linking Moscow to Kazan.
While rail travel between China and Europe has been possible for over a century with links to the Trans-Siberian Express, the lime involved has made it impractical. For instance, from Beijing to Moscow alone it takes more than a week traveling by train. However, using high-speed rail, the time from Beijing to London could potentially be cut to two or three days, making high-speed rail a fast and cost-efficient way to travel between China and Europe.
1. What directly makes traveling within China more convenient?A.Social changes. | B.High-speed rail. |
C.Lower expense. | D.Technology development. |
A.Promising. | B.Convenient. |
C.Impractical. | D.Adventurous. |
A.By giving examples. | B.By sharing experience. |
C.By making explanation. | D.By making comparison. |
A.Positive and content. | B.Indifferent and neutral. |
C.Favorable and confident. | D.Negative and concerned. |
The two have inked a comprehensive partnership, which includes a strategic investment by the former in the latter. Under the partnership, CMB will become the first bricks-and-mortar bank that can offer in-app credit card payments to Didi users. At present, users of Didi can only choose third-party payment solutions like WeChat Payment and Alipay to pay cab fares.
Zhao Ju, vice-president of CMB, said the cooperation with Didi was an important step in its mobile Internet finance strategy. “CMB's mobile payment is going to enter a new chapter by leveraging Didi Kuaidi's vast user base," he said.
According to a report by China Internet Network Information Center earlier this month, Didi holds 87.2 percent of China's private car hailing market. The company said it has received 1.43 billion car-hailing requests on its platforms in 2015, which means 1.43 billion payments were made via smartphones.
CMB is expected to use Didi to reach the core users of China's mobile payment market. Jean Liu, president of Didi, said many of the expats prefer payment by credit card rather than Alipay or WeChat. "The new partnership will help improve service quality and customer loyalty," she said. The investment makes CMB part of Didi's existing investors, including Tencent Holdings Ltd, Alibaba Group Holding Ltd and China Investment Corporation. Both of the companies declined to reveal the actual amount of the investment.
Liu, who showed up on Tuesday for the first time in public after her treatment for breast cancer, said the cooperation with CMB is for the long run and "the capital investment is only part of it".
Under the partnership, CMB and Didi will cooperate on a wide range of initiatives on financial services and online-to-offline cooperation. Apart from the in-app credit card payments, the two companies are going to launch joint credit cards in late February and automobile financing services for Didi's car owners. CMB's branches across China are expected to help Didi recruit more drivers.
"There is a lot of room for imagination in our partnership," Li said, adding in future people may use their CMB credit card reward points to pay for the ride on Didi.
Li Chao, an analyst with iResearch Consulting Group, said the partnership may not significantly boost CMB's mobile payment business. "Didi has educated the market for three years and its customers have formed the habit of paying by WeChat or Alipay. So I think CMB can only turn a very smart proportion of Didi users into its payment customer," he said. "But the move shows that China's traditional banking industry is finally thinking out of the box and looking for outside partners in Internet finance competition," he said.
Statistics from Big-Data Research showed that more than 90 percent of China's 9.3 trillion yuan ($1.41 trillion) worth of third party mobile payment market is donated by Alibaba and Tencent.

【推荐3】You’re stuck in a sea of standstill traffic when it begins: hunger pangs, the kind that release a steady stream of fast food fantasizing. With your grumbling stomach growing louder, your options are limited: You can wait a few hours for the roadways to clear or leave your car idling(挂空挡)on the highway while you set off on foot (please don’t do this).
Now Burger King, is betting that hungry drivers will welcome a third option: a direct-to-driver delivery concept the company has labeled the “Traffic Jam Whooper.” Reached by email, Gustavo Lauria, co-founder of the advertising agency We Believers, which developed the vehicle delivery concept, said the new approach allows the burger chain to gain advantage on a time of day in which the city’s terrible traffic typically slows business. “This was an opportunity for Burger King to generate new profits out of those hungry drivers”, Lauria added.
Lauria claims Burger King is the first fast food brand to deliver food to people in the middle of a traffic jam. In Mexico City, the company said, delivery drivers are already receiving an average of 7, 000 orders per day, mostly to homes and offices. To make the traffic jam delivery process possible, Burger Kings Mexico app activates the service after identifying crowded areas in Mexico City during periods of high traffic. Customers can only place an order if the app determines that the driver will be locked in traffic for at least 30 minutes and they are within a 1. 8-mile distance of a Burger King restaurant, the company said.
Early on, Lauria wrote, the act was met with disbelief. The challenges were complex: making sure real-time data of geographic location was accurate enough, and the creation of a hands-free way to take orders on cellphones in a country that has adopted serious punishment for drivers who use cellphones behind the wheel.
Though the company did not offer a timeline, Burger King says it expects to roll out the Traffic Jam Whopper in other overcrowded cities, such as Los Angeles, Sao Paulo and Shanghai.
1. What does the “Traffic Jam Whopper” (paragraph 2) refer to?A.A proposal intended to ease the traffic jam during peak hours. |
B.A practice which allows drivers to have food delivered directly to their cars. |
C.A platform which makes it convenient for drivers to order food via cellphones. |
D.An association monitoring whether drivers are observing traffic rules strictly. |
A.promote its business culture | B.make a shift in its sales pattern |
C.achieve an increase in its profit | D.popularize its business into more cities |
A.The Traffic Jam Whopper poses a threat to the safety of cyclists. |
B.Drivers will be allowed to type on their cellphones during traffic jams. |
C.Technological barriers may block the traffic jam delivery process. |
D.Drivers can instantly choose to activate Burger Kings app at will. |
【推荐1】I’ve been writing for most of my life. The book Writing Without Teachers introduced me to one distinction and one practice that has helped my writing processes tremendously. The distinction is between the creative mind and the critical mind. While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so.
Trying to criticize writing on the fly is possibly the single greatest barrier to writing that most of us encounter. If you are listening to that 5th grade English teacher correct your grammar while you are trying to capture a fleeting (稍纵即逝的) thought, the thought will die. If you capture the fleeting thought and simply share it with the world in raw form, no one is likely to understand. You must learn to create first and then criticize if you want to make writing the tool for thinking that it is.
The practice that can help you past your learned bad habits of trying to edit as you write is what Elbow calls “free writing”. In free writing, the objective is to get words down on paper non-stop, usually for 15-20 minutes. No stopping, no going back, no criticizing. The goal is to get the words flowing. As the words begin to flow, the ideas will come from the shadows and let themselves be captured on your notepad or your screen.
Now you have raw materials that you can begin to work with using the critical mind that you’ve persuaded to sit on the side and watch quietly. Most likely, you will believe that this will take more time than you actually have and you will end up staring blankly at the pages as the deadline draws near.
Instead of staring at a blank start filling it with words no matter how bad. Halfway through your available time, stop and rework your raw writing into something closer to finished product. Move back and forth until you run out of time and the final result will most likely be far better than your current practices.
1. When the author says the creative mind and the critical mind “cannot work in parallel ” in the writing process, he means ______ .A.one cannot use them at the same time | B.they cannot be regarded as equally important |
C.they are in constant conflict with each other | D.no one can be both creative and critical |
A.putting their ideas in raw form | B.ignoring grammatical soundness |
C.attempting to edit as they write | D.trying to capture fleeting thoughts |
A.To organize one’s thoughts logically. | B.To get one’s ideas down. |
C.To choose an appropriate topic. | D.To collect raw materials. |
A.it overstresses the role of the creative mind | B.it does not help them to think clearly |
C.it may bring about too much criticism | D.it takes too much time to edit afterwards |
A.It allows him to sit on the side and observe. | B.It helps him to come up with new ideas. |
C.It saves the writing time available to him. | D.It improves his writing into better shape. |
【推荐2】Marco Springmann and his colleagues, at the Oxford Martin School’s Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan (严格的素食主义者), the greenhouse gas emissions declines would be around 70%.
In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars---but it is cars, not steaks, that regularly come up in discussions about global warming.
Food, especially livestock (牲畜,家畜) also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.
However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. “I’m sitting here in Scotland where the Highlands’ environment is very man-made and based largely on grazing by sheep,” says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. “If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity.”
Plus, meat is an important part of history, tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.
And nowadays, moderation in meal-eating’s frequency and portion size is key to solving these conflicts. “Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions,” says Springmann, “like putting a higher price lag on meat and making fresh fruits and vegetables cheaper.”
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to carry out those changes.

【推荐3】For centuries, people have kept large amounts of cash at home during difficult times. But during the coronavirus (冠状病毒) crisis, things are different. Metal coins and paper money can be a source of worry rather than hope.
The fear is that these objects, possibly touched by thousands of people, could provide a way for the coronavirus to spread. Public officials and health experts have said that the risk is small. Still, some businesses refuse to accept cash and some countries have suggested that their citizens should stop using it altogether.
Zachary Cohle is an economics professor at Quinnipiac University in Connecticut. “In many areas, cash was already beginning to disappear due to the increased risk of robbery, the ease of Internet ordering, and the ubiquity (无处不在) of cell phones,” he said. “Sweden, Finland, Norway, Canada and others have slowly reduced cash use to the point where using it in large amounts seems unusual. Britain and Australia are expected to become cashless countries. And in China, cash use has dropped as electronic payment services have increased over the past ten years.”
“Cash ist Fesch” is a common saying in Austria and southern Germany. The words mean cash is beautiful. But since the virus outbreak, shops that have remained open there, like grocery stores, have encouraged people to pay with cards. And Germany’s central bank said 43 percent of Germans recently paid for goods and services with a card. The Bank of Japan estimates that cash makes up 53 percent of household assets (家庭资产). But the threat of the coronavirus could move the country toward going cashless, said Hiroki Maruyama, head of the nonprofit Fintech Association of Japan. He added, “The culture is slowly changing.”
However, cash use is still common in places like West and Central Africa, where many are too poor to pay for the cost of banking services. Dorothy Harpool teaches at Wichita State University’s W. Frank Barton School of Business. Harpool thought some people would rethink their use of cash during the crisis, but she said the world would not be cashless until everyone and every country has a reliable way to use the Internet.
1. Why is cash regarded as a source of worry?A.Cash may carry viruses after being used. | B.Cash can’t be used during the crisis. |

【推荐1】Lately, it’s felt like technological change has entered an incredible speed. Companies like OpenAI and Google have unveiled new Artificial Intelligence systems with incredible capabilities, making what once seemed like science fiction an everyday reality. It's an era that is raising big, existential questions for us all, about everything from the future of human existence to the future of human work.
“Things are changing so fast,”says Erik Brynjolfsson, a leading, technology-focused economist based at Stanford University. As he notes, this new wave of technological change looks like it could be pretty different. Unlike before, experienced and skilled workers benefited mostly from AI technology. In this new wave, it’s the less experienced and less skilled workers who benefit the most.“And that might be helpful in terms of closing some of the inequality that previous technologies actually promoted,” Brynjolfsson says. So one benefit of intelligence machines is-maybe-they will improve the know-how and smarts of low performers, thereby reducing inequality.
But it’s also possible that Al could lower the profit of the experienced, smart, or knowledgeable ones.AI could reduce inequality by bringing the bottom up, and it could also reduce inequality by bringing the top and middle down.
Of course, as Erik put, it’s also possible that Al could end up increasing inequality even more. For one, it could make the Big AI companies, which own these powerful new systems, wildly rich. It could also empower business owners to replace more and more workers with intelligent machines. And it could kill jobs for all but the best of the best in various industries, who keep their jobs because maybe they're superstars or because maybe they have seniority.
The effects of AI, of course, are still very much being studied and these systems are evolving fast, so this is just an assumption. This machine intelligence could upend much of the previous thinking on which kinds of jobs will be affected by automation.
1. What do the underlined words “the know-how and smarts” mean in paragraph 2?A.Experience and intelligence. | B.Skills and potential. |
C.Capacity and experience. | D.Outlook and talents. |
A.The senior with high rank. |
B.The inexperienced with low competence |
C.The learned with great credit. |
D.The poor with practical skills. |
A.The fast development of AI will promote the division of inequality. |
B.AI Giants will be the dominator in the future world of new AI systems. |
C.The best of all walks of life will survive the competition against AI systems. |
D.Lower rank workers with little knowledge are bound to be abandoned by employers. |

B.The Influence of the AI Inequality |
C.The Impact of the Artificial Intelligence |
D.The Future of the AI Generation |
【推荐2】To make artificial intelligence that can reason and apply knowledge flexibly, many researchers are focused on fresh ideas from neuroscience (神经科学). Should they be looking to psychology too? Researchers are working to develop new AI systems that can figure out simple abstract relations between objects and the reason behind them as effortlessly as a human brain.
Artificial intelligence has come a long way. In recent years, smart machines inspired by the human brain have shown superhuman abilities in games like chess and Go, proved remarkably expert at imitating some of our language skills. But with various other aspects of what we might reasonably call human intelligence — reasoning, understanding causality (因果关系), applying knowledge flexibly, to name a few — AIs still struggle. They are also inefficient learners, requiring large amounts of data where humans need only a few examples.
Some researchers think all we need to bridge the gap is ever larger AIs, while others want to turn back to nature’s blueprint. One path is to double down on efforts to copy the brain, better replicating (复制) the intricacies of real brain cells and the ways their activity is arranged. But the brain is the most complex object in the known universe and it is far from clear how much of its complexity we need to replicate to reproduce its capabilities.
That’s why some believe more abstract ideas about how intelligence works can provide shortcuts. Their claim is that to really accelerate the progress of AI towards something that we can say thinks like a human, we need to imitate not the brain — but the mind. “In some sense, they’re just different ways of looking at the same thing, but sometimes it’s profitable to do that,” says Gary Marcus at New York University and start-up Robust AI. “You don’t want a replica, what you want is to learn the principles that allow the brain to be as effective as it is.”

【推荐3】Artists everywhere are getting “understandably nervous” about recent advances in artificial intelligence. Last month, a winner of an art prize at the Colorado State Fair “sparked a violent protest” when he posted the news and explained that he’d created his image using an AI program. Critics quickly accused 39-year-old Lance Allen of cheating. To be fair, Allen had won in the digital art category and made no secret of how the image had been produced. But the rules of art making are clearly changing.
Allen’s creative process, to be clear, “was not a push-button operation, ”said Jason Blain in Forbes. He claims to have spent 80 hours on his entry, first on fine-tuning his text prompts (提示), then by touching up the final image using Photoshop and similar tools, then arranging to print the image on canvas. He made the finished product using AI much as a photographer creates an image using a camera.
But Allen, a tabletop game developer, is awed by AI’s capabilities and urges artists and illustrators to welcome the technology rather than fight it. “Art is dead,” he says. “AI won. Humans lost.” A more inspiring lesson to take from his victory, though, is that image generators are likely to “expand the appreciation for and creation of art” by opening the field to people, like him, who could never draw anything as detailed as his award-winning image. “If anything, we will have more artists,” and as the technology progresses, “we might see the emergence of art styles that none have seen before.”
You can’t blame traditional artists if they’re unhappy. Image generators work their magic, after all, by analyzing the aesthetics (美学) of millions of pre-existing images. One of the most complicated image generators “makes crystal clear just how destructive this technology will be,” said Loz Eliot in New Atlas. Given a specific prompt, it can produce an image of just about anything you can imagine and even follow the style of a favorite artist’s work. Its arrival marks “an incredible popularization of visual creativity” while aiming “a knife to the heart of anyone who’s spent decades improving their artistic techniques hoping to make a living from them.”
