Have you ever imagined    1     (live) in 2120, 100 years from now? Latest research describes robots, underwater cities and holidays in space. City planners and experts on space and architecture    2     (ask) to give their opinions on life in 2120. According to them, the way people live, work and play will be totally different     3     how we do these things today. They also said that over twenty years ago, people couldn’t imagine how the Internet     4    the smartphone would change our lives. But today, both have changed the way we communicate, learn and do daily things, and the changes in the next century will probably be even     5    (great).

Those     6     (question) in the research said that people may not go to the office in the future but will work at home instead. People will have advanced 3D printers which will let     7    download a design for furniture or a food recipe and then “print” the sofa, table or pizza at home.     8     will also be less need for visits to the doctor. People will have a home health capsule that will “diagnose” what the problem is and provide    9    (treat). They will also be going into space for holidays, and     10    (hopeful), to get resources that have been used up on earth.

The past thirty years     1    (see) the rapid growth of the Internet. Compared to the 1980s, there are now many more computers     2    (connect) to the Internet.

People hold different views about the future of cyberspace. Some pessimistic experts have a lot of worries, one of     3     is crime in cyberspace. In the future, terrorists may attack the world’s computers, thus causing chaos for     4    (we) human beings.

Many other people, on     5     other hand, are full of optimism about the future of the Internet. “In the future,” says Angela Rossetto of Cyberia magazine, “it is clear that we are going to see a huge development in shopping on the Internet. We will have     6    (entertain) from the Net and televisions will probably     7    (appear).”

Some experts say virtual reality, the use of computers with sounds and pictures that makes us feel as if we are     8     a real situation, will become a part of future life. “    9    (person), I believe we will work in virtual offices, shop in virtual supermarkets,     10     even study in virtual schools,” says Australian expert Peter Anderson.

In the not-too-distant future, we will be living in smart homes. These smart homes will ensure our     1     (secure), save us energy, and provide a more comfortable environment to live in. We will be using advanced technology every day — for    2     (automation) control of just about everything in our home. The future home will use integrated sensors     3     (tell) when you leave home each morning, and then go into an energy-efficient mode all by    4     (it). Your home will also learn your daily routine and     5     (prefer), so everything will be ready for you when you get home each evening. All controls will respond     6     voice commands, so if you want to change your routine, you just say aloud     7     you want and the home system will obey. In addition, the smart home     8     (programme) to monitor your health every day. Smart homes will be able to prevent serious damage from accidents. If there is     9     short in the electrical wiring, your smart home will detect it and provide you with the relevant information. This way, you will be able to fix the problem before your home becomes flooded     10     catches fire.

What will our cities be like in 2050? How much will artificial intelligence advance? Some scientists     1     (make) different predictions recently.

Joel E.Cohen from the The Rockfeller University says    2     is likely that by 2050 the majority of the people in the world will live in urban areas, and will have a    3     (significant) higher average age than people today. Cities will be     4     only realistic solution to housing a population that will expand     5     9.7 billion by 2050.

And the technology is expected    6     (advance) rapidly. According to Bill Michell, the late director of MIT Media Lab’s Smart Cities research group, cities of the future won’t look like “some sort of science-fiction fantasy’’ or “Star Trek’’, but virtual (实质上) reality will change    7     we live. Self-driving cars will make the roads more secure, driving more efficient, and provide     8     (fast) transport.

Charles Ebinger at the Brookings Institution thinks that by 2050 we will also have a so-called “smart grid” where all of our    9     (appliance) are linked directly to energy distribution (分布) systems,     10     (allow) for real-time pricing based on supply and demand. Such a technology would greatly benefit most people and reduced the consumption (消耗) of fossil fuel energy.

It definitely     1    (feel) good to be back in San Francisco again. And the city was able to rebuild itself after the earthquake     2     occurred in 1906. There are so many beautiful old buildings—many sitting on top of big hills,     3     (offer) great views of the city, the ocean, and the Golden Gate Bridge.

There is the Mission District near downtown,     4     of the oldest parts of the city. Many of the people living here are from Mexico or Central America. This district used     5     (be) a poor area of town, but is now a centre for art, music, and food. In fact, an art movement     6     (call) the “Mission School” started here. It’s influenced by graffiti art and comic art. A real mix of cultures here!

In the afternoon, I headed     7     a local museum that showed the     8     (history) changes in California. The museum did a     9    (reat) good job of showing how America was built by     10    (immigrant) from different countries and cultures.

Tomorrow evening, I’m going to a jazz bar in the Richmond District. Can’t wait!

The Future Life on Mars

Compared with the life we    1     (live) on the earth now, the future life on Mars will be     2    (total) different.

Firstly, without pollution on Mars, people will be able to drink cleaner water    3     breathe fresher air, so they will be    4     (health).The food on Mars will be     5    (differ) from our food now. People will just take    6     (pill) and drink man-made juice instead of eating bread and meat. Secondly, people will travel back to the earth or to other planets for sightseeing     7     spaceship. Additionally, there will be no     8     (fix) school and classrooms. Children will just fly to     9     classroom in the school spaceships. And people won’t work in factories or companies. They can stay at home,     10     (work) with computers.

Can you imagine what the future will be like? Some     1     (company) are looking to produce flying vehicles. That is amazing. If we have our own     2     (person) flying cars, we would fly at 480 kilometers per hour, avoiding busy roads. However,     3     seems that there is a long way to go before they get off the ground! One of the problems     4     (point) out by some people is what     5     (happen) if the flying cars break down.

Others are trying to build a practical suit "exoskeleton", a suit of robot arms and legs      6     follows your movement. It will allow the wearer     7     (lift) heavy objects and walk a long way! It is useful in many ways,     8     (especial) for people with disabilities. This suit might help people to walk again after disease and injury. But the disadvantage at the moment is battery life. A suit like this     9     (need) a lot of power but batteries only last about 15 minutes at the moment.

So in the future, whether we may fly to work     10     lift heavy objects, there are plenty of problems to solve before this is possible.

5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.
