2 . The idea of having car, a plane, drone(无人驾驶飞机) parked outside your home may not be as unlikely as it seems.

We are going to have personal air vehicles that are both cars and planes. At least that's Missy Cumming's vision of the future. It's basically the intersection of a drone with a robotic car, so your plane is also your car, but the quick development of technology is that you are actually driving neither.

Drones have a negative image in the media, says Cummings, because they are basically seen as spy cameras. But most people don't realize that when they are on a plane they are effectively travelling on a drone. The fly-by-wire technology that exists on all Airbuses and many crafts of Boeing is the exactly same technology that exists on drones.

The reason why drones are the answer to the future is that we are terrible drivers. Humans have a half-second lag(时滞) in almost any quick response that they need to have. Even a half- second delay can mean the difference between life and death, and computers and automated(自动化的) systems don't have that.

So, our transportation network of the future, both on the ground and in the air，will actually be safer when we turn it over to computers.

There really aren't any technological difficulties to this idea. The biggest difficulties we have in terms of giving up the car are psychological and cultural, but no new technology needs to be developed to have your own personal flying car. What we have to do is to improve production and reduce manufacturing costs.

People should be excited about this: it promises much in terms of safer travel, and people in parts of the world where the road and air networks are poor will be able to get the goods and services.

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.

In the future, the house will built with environmentally-friendly materials. The materials can produce electricity by take in air.

They can also keep the house at a pleasant temperature all year round, that makes the house more comfortably to live in. Besides, if there has an accident happening in the house, the host will receive a alarm call immediately. More importantly, once some natural disasters break off, the house can fly away to avoid it.

Although the house is still a dream, but I believe the dream will come true with the develop of science and technology.

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.

6 . Forging a 5G future

The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G? It's the latest generation of cellular (蜂窝状的) network technology.     1    

5G's benefits mainly come from speed and connectivity (连接).    2    People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.

    3     For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒).    4     It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors’ movements.

So what about 5G's connectivity?       5    . Imagine having a smart home that automatically turns the lights on when you open your front door.

"New things become possible when you can move information at a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler. "

No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.

7 . “Big data” lives up to its name: We produce 2.5 quintillion bytes (字节) of data every day through the digital connections that link people, objects, and devices. Every email, text, post, online search and doctor’s visit contribute to big data.    1    

Many believe it is. Stores are using it to improve our shopping experience.    2     In the United   States,   Macy's   department   store   credits   big data   with   improving   their   customer   satisfaction   and helping to increase sales by 10 percent.

Banks are also putting quite   a   lot   of   money   into big   data.    3     One   area   to   benefit   is customer service, where valuable information collected is supporting speedier decisions on loans (贷款) and credit while providing better protection against theft and even overspending.

Health care is also seeing a marked   difference. Data   collection   is   helping   to   reduce   preventable deaths, improve quality of life, predict and cure diseases.    4     Big data searches for patterns to predict how cancers will behave and recently led to the breakthrough discovery that a commonly used antidepressant (抗抑郁剂) has the potential to help find a cure for lung cancer.

Big   data   is   still   just   getting   started,   but   it already   influences   almost   every   area   of   our lives — mostly attempts   to   make   them better.   By 2021,   there will     be   200   billion   connected   devices.

    5     If computational power and data scientists can keep pace with such growth, the potential for big data to make an even bigger difference is huge.

8 . Want to get your package delivered via robots? Now there’s an app for that. If you live in Washington D.C., or Redwood, you may have glimpsed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many curious onlookers.

The autonomous machines were part of a pilot program last year by Starship Technologies focusing on delivering meals from local restaurants in dozens of cities around the world. This week, the company unveiled plans to broaden its delivery service beyond food to include package, a move that led it to declare itself “the world’s first robot package delivery service”. The next time you order food, this cute robot might roll up to deliver it. The package delivery service is not available to everyone yet.

The wheeled robots have a top speed of 4mph and can detect obstacles from 30 feet away. “The robot can operate through anything,” Nick Handrick, head of operations for Starship’s D.C. office, sad, “If you had something in the way-a stick –it’s able to climb sticks.”

To sign up for the service, which costs a little more than $10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address”, a unique address inside a Starship facility, where they can have package sent from places such as Amazon.com. Once a package is delivered to the Starship address, customers receive a text notification that allows them to schedule a home delivery via robot. The robots are opened by customers via a mobile phone code.

Barriers exist for robotic ground delivery, with many states requiring that humans be in control of delivery robots. Those regulations haven’t stopped Starship Technologies from accumulating experience on streets around the globe ahead of the company’s latest launch. The company says its robots have covered more than 125,000 miles in more than 100 cities in 20 countries.

9 . For centuries, people have moved to and lived in cities. These urban centres are places to find work, friends and fun. It's no surprise that they continue to grow as more and more people flood in hoping to make the most of the chances they offer but adding to the congestion and pollution that already exist.

According to a report by the United Nations, 54 percent of the world's population lives in urban areas and it predicts that by 2050,this figure will have increased to around 70 percent. But as more and more people move from the countryside to the city to get better chances, they can end up with nowhere to live.

This is true in places such as Rio de Janeiro, where the people from the countryside can't rent or buy a home,and they end up building their own communities and houses on unoccupied land. These are called shanty towns— poor communities where the houses are built out of cheap materials—and often don't have any electricity or water supply.

These are, of course, not the future cities we want to see. Some serious urban planning is needed to make our cities of the future good, safe and modern places to live in. This involves improving the housing conditions, the chances for education and employment and so on.

Something urban planners are looking at now is the creation of“smart cities”. According to John Rossant, founder and chairman of the non-profit organisation New Cities Foundation, technology is the way forward. He thinks that it's generally accepted that “cloud computing, ubiquitous Internet, robust 5G networks etc, will change our cities”. He says technology is really “a game changer” in urbanization (城市化). It would collect large amounts of data about how a city is working and may improve how a city functions.

10 . Welcome to your future life!

You get up in the morning and look into the mirror. Your face is firm and young­looking. In 2035, medical technology is better than ever. Many people at your age could live to 150, so at 40, you're not old at all. And your parents just had an anti­aging (抗衰老的) treatment. Now, all three of you look the same age!

You say to your shirt, "Turn red." It changes from blue to red. In 2035, "smart clothes" contain particles (粒子) much smaller than the cells in your body. The particles can be programmed (编程) to change your clothes' color or pattern.

You walk into the kitchen. You pick up the milk, but a voice says, "You shouldn't drink that!" Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

It's time to go to work. In 2035, cars drive themselves. Just tell your "smart car" where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology" is all around you.

So will all these things come true? "For new technology to succeed," says scientist Andrew Zolli, "It has to be so much better that it replaces what we have already." The Internet is one example—what will be the next?
