1 . "We are running out of space and the only places to go to are other worlds. ... Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth" These are the words of the famous scientist Stephen Hawking.

Hawking was not alone in this view. Many experts feel that the only way for humans to last far into the future is to colonize (殖民) other planets. That way, if an asteroid (小行星), a terrible discase, or some other disaster strikes Earth, we would still have a chance. Mars is one of the best choices. NASA, the private company SpaceX，and other organizations all have plans to send humans there. "Either we spread Earth to other planets, or we go out of existence,” SpaceX founder Elon Musk said.

But not everyone agrees that colonizing Mars or any other planet is such a great plan. The most common argument against going is that it's just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there, let alone set up a place for them to live. It's not even clear if humans could survive on Mars.

Maybe all the time and money people would pour into a Mars task would be better spent on more important projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid strike or disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet. In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems uninhabited, but it could possibly host some life. Human visitors may destroy this life or change the Martian environment forever.

What do you think? Should humans colonize outer space or stay at home?

2 . Those who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case at Japan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.

The first location of the unique hotel opened in July 2015 was at Nagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.

But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.

Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel in China, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.

3 . Life In The Future

What life will be like in the future is difficult to predict. It is, however, possible to use models to make forecasts about future developments. One way to catch a glimpse of the future is to examine some of the major trends in contemporary society.

Transportation

Current trends (趋势) indicate that transportation is becoming cleaner, faster and safer. Public transportation is already well developed in most urban areas of China. New technology is being used to make sure that the cars, taxis, buses and trains we use do not pollute the air. A good example of how transportation is changing is the new maglev train, which is environmentally friendly, energy­saving and travels at an amazing speed 430 km/h. To ensure safety, the train is controlled by an advanced computer system. Scientists are also developing new fuels and engines that will let us travel without worrying about whether we are polluting the environment.

Business

It will not be business as usual in the future. Many companies and consumers have already begun reforming the way they do business. E­commerce, or business done on the Internet is becoming more and more popular as people discover the advantages of online shopping. The Internet also makes it easier for companies to keep in touch with customers and companies in other countries. For people who do go out for shopping, shopping is no longer just a necessity. It has become a form of entertainment. Instead of searching a crowded store for basic goods, such as food and clothes, people want to go to a pleasant mall and combine shopping with fun.

5 . It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.

In recent years, many writers have begun to speak the ‘decline of class’ and ‘classless society’ in Britain. And in modern day consumer society everyone is considered to be middle class. But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an important part of British society. Britain seems to have a love of stratification.

One unchanging aspect of a British person’s class position is accent. The words a person speaks tell her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounded ‘educated’ and ‘soft’. The accents placed at the bottom in this study, on the other hand, were regional (地区的) city accents. These accents were seen as ‘common’ and ‘ugly’. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

In recent years, however, young upper middle-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ‘Common People’ puts forward the view that though a middle-class person may ‘want to live like common people’ they can never appreciate the reality of a working-class life.

6 . 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.

7 . Ever since the beginning of human civilization, we are trying to reduce manual efforts by making simple to extremely complex machines. The next step in the same process is robotics and automation. Robotics and automation is a field with abundant potential. It expands its scope from household applications to solving mysteries of the Universe to curing untreatable medical conditions.

Up until the beginning of 2020, robots of any kind are made up of nor-living materials. Recently scientists from the University of Vermont & Tufts University introduced Xenobots, which have opened a whole new Universe for this field. Xenobots are the world’s first living and self-healing microbots. These robots are designed with the help of computer-generated- evolutionary algorithm(算法). The living cells used for its creation are skin, heart and stem cell from the African frog embryos(胚胎).

These microbots are very basic in nature, made up entirely from the organic substance. They can move forward, turn around, spin in circles and flip over. They are smaller than a millimetre and can travel inside the human body. Just imagine the possibilities we will have, once scientist is able to teach Xenobots to do the desired task. One day they even might be able to fight cancer cells. They will be able to clear microplastics in the oceans and lots more.

But if these bots are a life form, why are we calling them robots? This is because scientists are designing them to move or work according to their wills. A certain arrangement for skin and heart cells in an Xenobot will make it move in a straight line, while a different arrangement of the same cells will be required to move them in circular motions.

Xenobots are positively a great step. Scientists are also calling them a brand new life form on the planet. The future is unseen but is undoubtedly full of countless possibilities.

8 . What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope about the future?

Futurologists predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have       disappeared by 2050. Instead, people will choose a program from a 'menu' and a computer will send the program directly to the television. By 2050, music, films, programs, newspapers and books will come to us by computer.

In what concerns the environment, water will have become one of our most serious problems. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don't act now.

In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the cars 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.

In the domain of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots-they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.

Last but not least, medicine technology will have conquered many diseases. Today scientists have discovered how to control genes. They have already produced clones of animals. By 2050, scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. Scientists will be able to do these things-but should they?

9 . You are just waking up in the spring of 2030. Your Internet of Things bedroom opens solar powered e-windows and plays gentle music while your smart lighting displays a montage (剪辑的)of beachfront sunrises from your recent vacation.

Your shower uses very little water or soap. It recycles your grey water and puts the extra heat back into your home's operating system. While you dress, your artificial intelligence (Al) assistant shares your schedule for the day and plays your favorite tunes.

You still start your day with a coffee but it comes from your lot refrigerator which is capable of providing a coffeehouse experience in your home. A hot breakfast tailored to your specific nutritional needs (based on chemical analysis from your trips to the “smart toilet” is waiting for you in the kitchen.

When it's time to leave, an on-demand transport system has three cars waiting for you, your wife (or husband) and your kids. On the road, driverless cars and trucks move with mathematical accuracy, without traffic jams, routine maintenance or road rage. Accident rates are near zero.

On the way, you call your R&D team, who are enveloping a day's work in Shanghai. Your life-sized image is projected (投射)into the China Innovation Centre and your colleagues see you as if you were sitting in the room. It’s a bit surreal for them to see you in the morning light given that it's dark on the Bund, Shanghai's waterfront, though the novelty disappears after a few uses.

You review the day's cloud-based data from your Shenzhen manufacturing center, your pilot project in San Diego, and your QA team in Melbourne. The large amounts of datasets were collected in real-time from every piece of equipment and have been beautifully summarized by your company's AL All these facilities are closely maintained and operated through a advanced predictive analytics platform.

Pleased with the team's progress, you end the call and ease into a good book.

This is the future and it will be here sooner than you think.
