2050 seems a long way away, but it is not impossible to predict the future though. With the speed we are moving now so many amazing things are going to happen in the future.

【小题1】 Let's start our predictions.

·The Internet will be free for everyone.

The Internet is really a key driver these days. 【小题2】 There have already been attempts like Facebook's Free Basics. Though it hasn't happened yet, there is a very strong possibility that the Internet will be free for everyone in the future.

·【小题3】

With the increasing population, it is not very hard to predict that common methods of transportation will not be enough. There will be much heavier traffic on the road. So in this case personal airplanes will be a handy method of transportation for common people.

Of course, there will be proper air traffic control for these personal airplanes.

·Most cancers will be treated successfully.

【小题4】 It will be a huge achievement in the history of medical science. Many studies are already showing a trend (趋势) towards this.

·Humans will live on other planets.

There will be great achievements in space research. 【小题5】 

We will receive more intelligent signals from space. Chances are we will be able to find the next Earth-like planet.

Computer technology is still developing rapidly.The computer of the future will continue to increase in value and performance while decreasing in cost.It will become smaller，but faster and more powerful.

It is possible to make some guesses about what the future of the computer will look like，based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies，but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing (量子计算) and nanotechnology (纳米技术)．

Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.

Nanotechnology could also change the face of computing，by creating computers that could be very powerful，though they are tiny in size.These computers could be incorporated (并入) into everyday objects，including electrical appliances (电器)，clothes and even the human body.We will be able to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes，such as work.

Quantum computing and nanotechnology will be able to play new roles，which will make us live greener lives，as well as enjoy better health and happier lives.

Futurologists are making a lot of predictions about our future life and they are predicting how we will travel, work and live in the next 30 years. By 2048, some futurologists foresee that some talking"   buildings will appear in our life.

By the middle of the century, it^’s believed that buildings will be able to “talk" to people through various sensors when the heating needs to be turned on. As a result, there will be no switches. Instead, a lot of networks will appear, which can be compared to a human nervous system. In the next 30 years, buildings will be made from concrete plastics and shape-changing materials. All of them can heal themselves at that time. As architects (建筑师)are racing to develop the world's tallest buildings, there will be a need for new kinds of elevators, through which vehicles could even travel into the buildings. German engineers have already started working on such technology called Multi.

By mid-century, scientists believe that buildings will be miles tall. Some of them may be very large and they can function as small cities. By comparison,at present, the world's tallest building, the Burj Khalifa in Dubai, measures 829. 8 metres high. As the future building can rise through the clouds,their windows will be replaced by virtual screens. In this way, people can choose any view as they like.

At height extremes, a London Spaceport is also likely to come into being by 2048 as the space industry develops very quickly. There is a huge cost advantage going to space from as high a base as possible, so a spaceport is very likely to be over 10km and even as much as 30km, using carbon- based materials.
