2 . 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. |
3 . What if we had the power to control time, instead of moving from the past to the present to the future? What if we could jump, loop and travel through time in a machine? What if we could go wherever and whenever we pleased?
This ability would allow us to witness historic wonders, change decisions and see people from the past. We could right wrongs and stop wars from starting.
The mysterious puzzle of time has kept people debating its nature for hundreds of years. Science fiction writers have turned it into imaginative stories. Some scientists have even attempted to explain it using math. This math tries to make the dream of time travel come true.
The scientist Albert Einstein said that time and space are one thing. He called it “spacetime.” Einstein said that there are three dimensions in space: height, width and depth. A scientist named Hermann Minkowski added time as a fourth dimension.
Einstein introduced two ideas that have led to theories about the possibility of time travel. The first is relativity. The idea of relativity is that the force of gravity causes space to bend, which causes time to twist. The second idea focuses on special relativity. The idea is that a traveler moving super-fast through flat spacetime will enter the future. Einstein considered time “relative” because it is measured based on where we are on Earth or in space.
Stephen Hawking is a famous scientist. He believes that a time machine will never be built. If it were possible, he thinks we would already know. If a time machine could be built, how come no one from the future has invaded us?
The first science fiction story with this theme is The Clock That Went Backward by Edward P. Mitchell, which was published in 1881. Since then, thousands of books, films and television shows have explored the idea of time travel, in which some tools such as phones, watches, photographs and old books take travelers backward and forward.
Will time travel ever happen? Who knows? Most important is to keep your eyes open and have a sense of wonder.

4 . All the efforts you put into studying at university may not have been enough—because robots could be coming for your job. A new study finds that as many as 800 million workers could be replaced by robots by 2030.
The study from the McKinsey Global Institute estimates that between 400 million and 800 million individuals could be replaced by automation(自动化) or robots and need to find new jobs by 2030 around the world. It estimates that 30 percent of the hours people spend on working globally could have been automated by that time.
Those most affected will be people who work in predictable environments doing tasks such as operating machines and preparing fast food. Those who make a living by collecting and processing data also face a high risk of being replaced by robots. But people who work in less predictable environments such as gardeners, plumbers, and childcare staff face a smaller risk, because their roles are technically difficult to be automated and often command relatively lower wages, which makes automation a less attractive business proposition(商业提议).
However, it’s not all doom for the future of employment. The Study notes that automation sometimes allows workers to remain employed in a different position. “Even when some tasks are automated, the employment rate in those occupations may not decline because workers may perform new tasks,” McKinsey &Company wrote in a release on its website.
It noted that China has the largest number of employees who would need to switch occupations, up to 100 million if automation was adopted rapidly, or 12 percent of the 2030 workforce. The numbers are higher in more advanced economies, with up to one-third of the 2030 workforce in America and Germany needing to switch occupations, along with nearly half of the 2030 workforce in Japan. Countries which fail to prepare workers for transition to new jobs will feel the impact of a rise in unemployment and depressed wages, according to the study.

5 . The home of the future won't be completely different and we will be living in houses and flats just as we do today. But people will want to shape their homes to match their dreams. No two homes will be the same. People will be able to buy "house kits" containing a basic house structure, with movable walls, doors and windows. They will put together the different parts to create the home they want.
Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won't disappear because machines can't replace them. Teachers will still exist because students need human contact. But they will be using modem technology in class more and students will be working more at home. The medical technology revolution and space travel will create new jobs which we can only imagine today.
Space holidays will develop in the future, but these holidays won't be for everyone because they won't be cheap. Short space trips will develop first; then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will have been holiday centres on the moon with leisure facilities（休闲设施）for families.
Paper won't exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reusable paper.
The laws of physics tell us that the earth is going to disappear some time in the future. This isn't going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes. We will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it, or we leave and move to another planet. There won't be any other choice.

6 . Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that’s a conservative estimate(保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

8 . These days, it seems like everyone wants to go out into space and live on new planets.Rather than depend on another pre-existing planet, could we make a new, proper planet ourselves?
To start with, if we do want to be living on it, we should find a good place in space to put the new planet. We’d want it to be in a habitable zone, meaning the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid(液态的) water.
We’d also need the right materials to make the planet. Our Earth is made up of many different elements(元素). If we made our own new planet we’d probably want it to have similar elements and a similar structure(结构) We’ d also want enough water to form some oceans.
But even if we get all of the materials creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.
We would probably also need a lot of food since there s going to be many scientists and astronauts out in space working on this project!
According to NASA, each astronaut uses about 0. 83 kilograms of food per meal, including 0.12 kilograms of packaging(包装) material. Without the weight of the packaging material, we’d need about 780 kilograms of food just to feed one astronaut for a year.
Putting all these together could make it possible to make our own planet one day! In reality, creating a new planet would probably require a very modern technology and there would be tons of other things to think about. And if this is even possible, it likely won’t happen for a very long time.
1. What's the first thing we should do if we want to create a new planet?| A．To prepare enough food. |
| B．To design its inner structure. |
| C．To find a proper place to set the planet. |
| D．To collect materials similar to our Earth. |
| A．Our Earth. | B．Outer space. |
| C．The new planet. | D．The ocean water. |
| A．About 0. 12 kilograms. | B．About 0. 71 kilograms. |
| C．About 0. 83 kilograms. | D．About 0.95 kilograms. |
| A．It is a waste of money and time. | B．It should be one of NASA’S next plans. |
| C．It is not a good idea for humans. | D．It won’t come true in the near future |
9 . Each of Apple’s products such as the iPhone and the iPad sounds cool and has become a fashion. Apple has cleverly taken advantage of the power of the letter “i”, and many other brands are following suit. The BBC iPlayer, which allows Web users to watch TV programs on the Internet, used the title in 2008. A lovely bear — popular in the US and the UK — that plays music and video is called iTeddy. A simplified version of The Independent was launched in 2010 under the name i.
In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use.
Most “i” products are aimed at young people and considering the major readers of The Independent’s sister paper I, it’s no surprise that they’ve selected this fashionable name.
But it’s hard to see what’s so special about the letter “i”. Why not use “a” , “b”, or “c” instead? According to Tony Thorne, former Director of the Language Centre at King’s College London, “i” works because its meaning has become unclear. “When Apple uses ‘I’, no one knows whether it means the Internet, information, individual or interactive,” Thorne told BBC Magazines. “Even when Apple created the iPad, it seems it didn’t have one clear definition,” he said.
“However, thanks to Apple, the term is now connected with portability (轻便),” added Thorne.
Clearly the letter “i” also agrees with the idea that the Western world is centered on the individual. Each person believes they have their own needs, and they love personalized products for this reason.
Along with “Google” and “blog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last decade.
But as history shows, people grow tired of fashion. From the 1900s to the 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern.
However, as we entered the new century, the trend unavoidably disappeared.
1. Why do people use iPlayer?| A．To listen to music. |
| B．To make a call. |
| C．To watch TV programs online. |
| D．To read newspapers. |
| A．Engineers. |
| B．Young readers. |
| C．Fashionable women. |
| D．Old readers. |
| A．easy to carry |
| B．environmentally friendly |
| C．advanced |
| D．personalized |
| A．“i” products are often of high quality. |
| B．Actually nobody likes products with “2000”. |
| C．Fashion is closely connected with time. |
| D．The popularity of “i” products may not last long. |
