1 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

2 . 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.

3 . A robot with a sense of touch may one day feel “pain”, both its own physical pain and sympathy for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.
Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial “pain nervous system,” as Asada calls it, may be a small building block for a machine that could ultimately experience pain. Such a feeling might also allow a robot to “sympathize” with a human companion’s suffering.
Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic looking child’s head, these touch and pain signals can be converted to emotional facial expressions.
A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin “allows the possibility of engagement in truly intelligent ways”.
Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care for people in need, the elderly, for instance.
But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that’s able to compute an internal feeling accurately, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is “along the lines of having a robot, for example, that smiles when you talk to it,” Damasio says. ‘It’s a device for communication of the machine to a human.” While that’s an interesting development, “it’s not the same thing” as a robot designed to compute some sort of internal experience, he says.

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.
1. Mr. Basille gave the boy a quarter out of his coin changer to __________.| A．show his magical power | B．pay for the delivery |
| C．satisfy his curiosity | D．please his mother |
| A．He wanted to have tea there. | B．He was a respectable person. |
| C．He was treated as a family member. | D．He was fully trusted by the family. |
| A．Nobody wants to be a milkman now. | B．It has been driven out of the market. |
| C．Its service is getting poor. | D．It is not allowed by law. |
| A．He missed the good old days. | B．He wanted to tell interesting stories. |
| C．He needed it for his milk bottles. | D．He planted flowers in it. |
5 . Farms of the Future
Skyscrapers(摩天大楼) are the ultimate symbol of urban life. By 2050, almost 80 percent of the earth’s population could live in cities. The human population could increase to 9.1 billion people yet the amount of land available for farming will be the same.
Vertical farms, where farmers could grow crops in environmentally friendly skyscrapers, could be the solution. In spite of concerns over high costs, experts want to make these urban farms a reality and use these skyscrapers to grow crops.
Vertical farms would have many advantages, experts say. The food would be grown with minimal effects on the environment. Unlike traditional farming, vertical farming would not force animals out of their habitats by taking over large areas of land, nor would it pollute the air with the use of heavy farming equipment.
Growing prosperity has led to many people demanding that all foods are available all year round. Indoor farming could produce crops constantly and crops would not suffer from weather-related problems like drought or flooding. In addition, the use of agricultural chemicals for controlling insects would be minimal.
Experts agree that the new farming practices are needed to support the planet’s need for more and more food at affordable costs, both to the farmer and to the consumer. Vertical farms may be a small-scale answer, but the best ideas could be yet to come.
| A．Still, there are some people who are critical of vertical farms. |
| B．That is where vertical farms are often needed for year-round crops. |
| C．So how to meet the increasing food needs of our planet could be a big problem. |
| D．For these reasons, natural light cannot be a workable solution for vertical farms. |
| E．Vertically grown food is grown in environmentally controlled conditions in big cities. |
| F．Those farms would also reduce the cost and negative effects of transporting food over distances. |
| G．They believe that we can increase the food production by changing our thinking from out to up. |
6 . The future home is something that people have talked about for decades. Because the future home idea inspires our imagination, scientists and engineers have been working hard to develop different systems to make houses “smarter”.
The video camera at the entrance recognize visitors using facial recognition. The facial recognition software of the future home will not only recognize friends, but strangers as well. And the software in the future home will run the strangers faces against a database of criminals.
The future home will also have smart application appliances (家电) as well. There will be a vast networking system connecting them. Ovens, microwaves and refrigerators will be controlled automatically, so remote cooking will be a possibility and meals are prepared for your arrival.
There will also be a green systems in place such as saving and reusing washing water and bathwater. Plants and people may receive pure or mineralized (含矿的) drinking water.
If you think this future home idea is pie in the sky or science fiction, then think again. Most of the systems described here are either in development or already out in the market. Future homes may not be standard yet for the middle class but this is not as far ahead as many people would think.

| B．A smart networking system |
| C．Software in future home |
| D．Various household appliances |
7 . Now cities are full of cars. Some families even have two or more cars. Parking (停车) is a great problem, and so is the traffic in and around the cities. Something will have to be done to change it. What will the cars of tomorrow be like?
Little cars may some day take the place of today’s big cars. If everyone drives little cars in the future (将来) there will be less pollution (污染) in the air. There will also be more space for parking cars in cities, and the streets will be less crowded. Three little cars can fit (适合) in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer, too. What is more, these little cars can go about 65 kilometers per (每) hour.
Little cars of the future will be fine for getting around a city, but they will not be useful for long trips. If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the slower small ones.
1. is the big problem for those people who have cars.| A．Money | B．Parking | C．Driver | D．Waiting |
| A．more | B．much | C．less | D．no |
| A．one third of | B．two thirds of | C．as big as | D．as small as |
| A．long trips | B．journeys | C．everyday life | D．sport |
8 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.
Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.
Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.
“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.
Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).
Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”
Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.

9 . With over 4.1 billion people, or around 55 percent of the world’s population, living in urban areas, cities and towns worldwide are getting increasingly jammed. In addition to spending hours stuck in traffic, residents are also exposed to high air pollution levels caused by transportation emissions(排放). Now, Saudi Arabia hopes to overturn urban living with “The Line”—a futuristic city designed around nature, without cars, roads and crowded places!
The totally different city, announced on January 10, 2021, is the brainchild of Saudi Crown Prince(王储)Mohammed bin Salman(MBS).Located in Neom, a 10, 000-square-mile high-tech planned development on the Red Sea coast. The Line will be the base of MBS’s Saudi Vision 2030. The strategic plan aims to diversify Saudi Arabia’s oil-dependent economy into other fields, like tourism, and create exciting job opportunities for its citizens.
The 105-mile-long city, expected to cost between $100 billion and $200 billion, will be built along a straight line and comprise several self-sustaining communities. To ensure all services are within a short, five-minute walk, each community will feature a three-layer infrastructure(基础设施)．
There will be no cars or roads on the top “pedestrian layer”, so residents can freely walk and bike in the surrounding green spaces. The second “service layer”, will include all essential daily services, such as schools, medical clinics, leisure facilities, and grocery stores. The third “spine layer” will house ultra-high-speed transportation and autonomous vehicles transporting residents across communities in less than 20 minutes. The entire city will be powered with renewable clean energy sources such as solar and wind, and possibly even hydrogen．
If all goes according to the plan, construction of this groundbreaking, complex infrastructure project will start before the end of 2021. In addition to providing up to a million residents with a clean and stress-free living environment, the Line is expected to create 380, 000 new jobs, promote economic diversification, and contribute a shocking $48 billion to Saudi Arabia’s Gross Domestic Product(GDP)by 2030. More importantly, MBS believes it will provide governments worldwide a blueprint for how people and planet can co-exist in harmony.

| C．MBS：An Influential Leader of Saudi Arabia |
| D．MBS’ Vision of a Futuristic Zero Carbon City |
10 . Life in the future will be different from the life today. Between then and now many changes will happen. But what will the changes be?
The population is growing fast. And most of them will live longer than people now.
Computers will be much smaller and more useful, and there will be at least one in every room. And computer studies will be one of the important subjects in schools then. People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Travelling will be much cheaper and easier. And many more people will go to other countries for holidays.
There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruits and vegetables. Maybe people will be healthier. Work in the future will be different, too. Robots will do dangerous and hard work. Because of this, many people will not have enough work to do. This will be a big problem.
1. In the future there will be________.| A．much more fruits | B．more people | C．fewer vegetables | D．less people |
| A．work long hours | B．work fast | C．walk on foot | D．eat meat |
| A．fruit | B．fish | C．meat | D．rice |
| A．many people don’t have to work |
| B．many people will not be able to find work |
| C．people have to work fast |
| D．all the work will be done by robots |
