1 . 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.

4 . When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note — “Please add a bottle of buttermilk next delivery” — and place it in the box along with the empty bottles. And then, the buttermilk would magically (魔术般) appear.

All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.

Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch (门廊) . Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

No one can foretell the future of technology exactly, because no one can see the future. However, there are reasonable     1     (argue) based on the advances and trends in technology in the past. For example, it’s reasonable to predict that computers will continue to become more powerful, numerous and cheaper. Areas with huge potential,     2     are just beginning to be made use of today, like biotechnology, will continue to produce fruit.

Technology in general will probably continue to improve,     3     (create) both promises and risks. In     4     area of computers, someone might interact with hundreds of embedded microchips (嵌入式微芯片) throughout the home and the office. In the future, it will be many thousands.     5     some have called “ubiquitous computing” —— computers everywhere helping us with everything —— will be caused by increasing bandwidth and decreasing costs. Some viewers, especially Bill Gates, believe the next few decades     6     (characterize) by long-awaited revolutions in robotic technology. Other futurists see trends in automation technology leading to desktop factories that enable users     7     (make) objects from a host of simple     8     (origin) parts.

Apart from above areas, there are dozens if not hundreds of areas that will continue to advance technologically. One thing is     9     sure: the future will have better technology than the past did. But will we put     10     to better use? Only time and effort will tell.

News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.

Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?

To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.

Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs

Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.

10 . What are your retirement plans? Keep working? Get more exercise? Or learn something new? You may put them on hold. There’s a chance that, sooner or later, you might have to move further than you were thinking, as far as mars.

On Thursday, National Geographic will show the first-ever Mars show home, giving earthlings (地球人) an idea of what their life could look like on the Red Planet. In the not-so-distant year of 2037, the igloo-shaped structure could be the home of your future.

It shows a house built using recycled spacecraft (航天器) parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognizable—a kitchen, a bedroom—but there are fundamental differences that are important to human survival.

As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent (永久的) shelter from the sun; society will move largely indoors. Most buildings will be connected by underground passages and the houses won’t have windows. The homes will have simulated solar lighting, or natural light that has been bent several times.

Walls will need to be 10 to 12 feet thick to protect people from dangerous rays (光线) that can pass through six feet of steel, and a double air-locked entrance to keep the home under proper pressure.

“We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre,” says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci-fi. “10 to 20 years from now there will certainly be people, on Mars.” Petranek says.

“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will,” Petranek says. But two main factors have “completely swung public attitudes”.

The private companies’ participation has forced government agencies to speed up their game, and influential films such as Gravity and The Martian have caught society’s eye.
