3 . During the Beijing 2022 Winter Olympics, foreign journalists not only enjoyed the Chinese athletes’ excellent performance, but experienced “the speed of China” in the development of high-speed rail.
On Feb. 14, 57 journalists from 36 Chinese and foreign media groups were invited by the 2022 Beijing Media Center to visit the city’s rail transit command center to explore the “secret” of Beijing’s high-quality development in the field.
Beijing has formed a safe, convenient, efficient and green rail transit system. It now consists of 27 metro lines, increased from two in 2001 when Beijing won the bid to host the 2008 Olympic Games. Last year, the city’s metro lines together handled nearly 10 million passenger trips per working day, accounting for 57 percent of the total number carried by urban public vehicles.
Compared with car travel, each subway passenger can reduce 77 percent of their carbon emissions, which means the total reduced carbon emissions can reach 7. 38 million metric tons a year. This is equal to the amount of carbon dioxide absorbed by 410 million trees, experts said. In addition to efficiency and ecological protection, the city’s urban rail transit is becoming more intelligent. For example, the west part of Metro Line 11 is known as a line serving the 2022 Winter Olympics, which features a fully automated driving mode under staff supervision at the beginning of the train’s operation.
Although China was behind developed countries in high-speed railway development, it has accumulated abundant experience in constructing all types of railways, including high-speed and railways at high altitudes and carrying heavy loads. The country also has the longest high-speed rail mileage, which accounts for more than 66 percent of the world’s total.
“China’s high-speed trains run across rivers and mountains to reach all directions, from forests and snowy fields in the north to wetlands south of the Yangtze River, and from the desert in the west to the East China Sea,” said Zou Wu, a senior engineer at the China State Railway Group. “The country’s high-speed railway network covers 92 percent of the cities each with a population of more than 500, 000 people.”

6 . Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
What does “maintenance” underlined in paragraph 3 refer to?
A.Personnel safety. | B.Assistance from drones. |
C.Inspection and repair. | D.Construction of infrastructure. |

9 . 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 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 driveress 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 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 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. 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.

10 . The Gurugram-based startup Rivigo was founded in 2014 by Deepak Garg. The central objective of the now billion-dollar company was to create a model where no truck driver would drive for more than 5-6 hours at a stretch and would reach home the same day.
Looking to build a company, Deepak realized that the rise of e-commerce had dramatically increased the demand for trucks, yet in India the industry was struggling with a shortage of drivers. How could this be in a country of over a billion people with a high unemployment rate— despite healthy wages for truck drivers?
To solve this puzzle, Deepak visited small villages where many truck drivers could be found. During his one-on-one conversations he discovered that since truck drivers are almost always on the road, they often develop bad habits such as heavy drinking. Partly because of this, few villagers wanted a son to become a truck driver or a daughter to marry one. What, then, was the solution? Could it be to bring the drivers back to their homes every night? That could work --- but how could he make it happen if a trucker’s trip took three or four days?
A relay service, Deepak realized, could solve the problem. Effectively, he built truck stops four hours apart along a selected route. A driver could go from point A to point B, drop his truck there and pick up another truck to drive from B back to A. Another driver in turn would pick up the truck from B and take it to point C, and so on. This not only brought drivers home each night, but created great value for logistics (物流) companies. A truck that was previously used for only 10 to 12 hours a day, allowing drivers time to sleep and eat, could now operate for more than 20 hours, cutting total delivery times by almost half.
To be sure, there’s a lot of technology behind the scene. But the founder strongly believes being humane (人道的) above anything else is the biggest factor that distinguishes him from the common crowd.
