1 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.
In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.
In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.
Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.
Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?

2 . If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare’s play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.
The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is the science fiction novel The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.
But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking said you could travel into the future with a really fast spaceship—going at nearly the speed of light. Though building such a spaceship would of course be no simple task.
Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveller were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveller wasn’t born, how would he travel back in time?
And would you really like to visit the future? In H. G. Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles (触角). If that’s what’s in store, maybe we are better just living in the present day after all.

C.Supportive. | D.Unconcerned. |
3 . 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.

5 . European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future. Researchers from the European Space Agency,or ESA,carried out the experiments at a laboratory in the Netherlands.
The team says ESA’s experimental“plant”was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith,a top layer of dirt and rock pieces that sit on the surface of the moon. Samples of regolith returned from the moon have confirmed that the material contains about 45 percent oxygen by weight. However,the oxygen is chemically locked in the form of minerals or glass,so it is not easily available for use. Having real samples of regolith from the moon made it possible for the researchers to create the simulated moon dust material used during testing.
The oxygen extraction(提取)process is carried out using a method called molten salt electrolysis(熔盐电解). This includes first placing the regolith in a metal container. Calcium chloride salt is added to the mixture,which is then heated to 950 degrees Celsius. At this temperature,the regolith remains solid. Next,an electrical current is passed through the material. The researchers say it is this step that results in oxygen being extracted from the regolith. The study reported that up to 96 percent of oxygen in the simulated moon dust was extracted during the experiments.
ESA’s long-term goal is to design an oxygen-producing“pilot plant”to operate full-time on the moon. The first technology demonstration of the system is expected to take place in the middle 2020s. Beth Lomax,a lead researcher on the project,said,“Being able to acquire oxygen from resources found on the moon would obviously be hugely useful for future lunar settlers,both for breathing and the local production of rocket fuel. ”The researchers reported that“as a bonus,”the process also results in the production of usable metallic materials.
ESA and the US space agency NASA are both working on plans to return human beings to the moon. NASA has set a goal for 2024 with the aim to keep humans on the moon for long periods.

6 . Japan's biggest airline is betting that the future of travel isn't traveling at all. For the last month, a married couple has been interacting with a robot—called an Avatar—that's controlled by their daughter hundreds of miles away. Made by ANA Holdings Inc., it looks like a vacuum cleaner with an iPad attached. But the screen displays the daughter's face as they chat, and its wheels let her move about the house as though she's really there.
“Virtual travel” is nothing new,of course.Storytellers, travel writers and artists have been stimulating the senses of armchair tourists for centuries. It's only in recent decades that frequent, safe travel has become available to the non- wealthy.
Yet even as the world's middle classes climb out of the armchair and into economy-class seat, there are signs of a post-travel society emerging. Concerns about environmental sustainability cause loss to airlines which release much carbon. And the aging of abundant societies is both restricting physical travel and creating demand for alternative ways to experience the world. For the travel industry, virtual reality offers an attractive response to these trends.
Of course, new technologies encourage far-out claims. ANA doesn't plan to start selling Avatars until next year. Profits, too, will probably be difficult to make: By one estimate, the global market for this kind of technology will be worth only about $300 million by 2023. By contrast, ANA's traditional travel business brought in more than $19 billion last year.
But if the business value for virtual vacations is still weak, the market for technologies that bridge physical distances between families and coworkers seems likely to only expand. ANA's robots may not replace its airplanes any time soon, but they ll almost certainly be a part of travel's high-tech future.
1. Why does the author use the example of a couple interacting with a robot?A.To show the Japanese are crazy about travel. |

8 . Scientists have discovered a new material that can hold the key to unlocking the potential of hydrogen-powered(氢动力) vehicles.
As the world looks towards a gradual move away from fossil-fuel-powered cars and trucks, greener alternative technologies are being explored, such as electric-battery-powered vehicles. Another “green” technology with great potential is hydrogen power. However, the major obstacles have been the size, complexity, and expense of the fuel systems—until now.
An international team of researchers, led by Professor David Antonelli of Lancaster University, has discovered a new material that offers a solution. The new material would be used to make molecular sieves(分子过滤器) within fuel tanks—which can store the hydrogen and work alongside fuel cells in a hydrogen-powered “system”. It makes the design of tanks far smaller, cheaper, more convenient and energy-denser than existing hydrogen fuel technologies, and significantly outperform battery-powered vehicles.
The cost of manufacturing this new material is so low, and the energy density it can store is so much higher, that the hydrogen fuel cell systems cost five times less than ordinary batteries as well as providing a much longer range—potentially enabling journeys up to around four or five times longer between fill-ups.
The new material makes the cooling system unnecessary. This is crucial because it means cooling equipment does not need to be used in vehicles, resulting in systems with the potential to be far more efficient than existing designs.
Although vehicles, including cars and heavy goods vehicles, are the most obvious application, this material can also be used in portable devices such as drones or within mobile chargers so people could go on week-long camping trips without having to recharge their devices. It could also be used to run a house or a remote neighborhood off a fuel cell.

9 . In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.
The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks — provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.
But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.
Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.
So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.
