What will the world of the future be like? There are plenty of people who are happy to give their opinion of what we will be doing in 2050. Here are two predictions about the world of tomorrow.

When we dream about the future, many like to think of owning a personal flying car. The advantages are obvious. This technology would allow total freedom of movement. We could fly at 480 km per hour, avoiding traffic lights and busy roads.However, some people believe there will be problems with traffic control. If the cars become popular, there is likely to beair traffic jam. Another big problem is mechanical failure. What will happen if the cars stop working? These are problems we must expect if flying cars become a reality.

Three-dimensional printing is another new technology with excitingpossibilities. 3D printers are used to build an object with liquid plasticThey build the object layer by layer until it is complete. Car companiesalready use 3D printers to make life-size models of car parts, and medicalcompanies use the technology to make man-made body parts. As we move into the future, 3D printing will revolutionize the way we shop, the way we manufacture and the way we treat sick people. The disadvantage is that such equipment will be extremely expensive.

So in the future, we might be able to fly to work or print out new shoes.Although there are some problems to solve before this will be possible, we can certainly dream of a world where technology makes life easier and safer for millions of people.

Here is a page from a magazine called Future. Read the following information about things that may happen in ten years.

(A)Cars will run on solar power(太阳能) and will be much cleaner. They will be much safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself.

New cities will have to be built in the sea. Some of them will have two levels(层). People will live on the upper level; the lower level will be used for traffic, shops and factories.

Biotechnology(生物技术) will make food better and healthier. Plants without insects or illnesses(病虫害) will be developed. (B)The taste of fruit and vegetables will be better and food will be kept longer.

Many new ways to cure(治愈) illnesses will be found. People will use products of genetic engineering(基因工程产品) to cure more illnesses. However, some new illnesses will appear.

Life in the year 3044 is very different     51     life in the 21st century. We still do many of the things you did, but we do them     52    . For example, we now have e-friends to help us and keep us company. An e-friend is a machine that looks just like a person. It can walk and talk and can do almost everything we do. My e-friend is a lot like me and we have a lot of     53     together. She helps me with my homework and we often go     54    . She is able to take care of me if     55     happens, so I always feel     56     when we are together. She can also send me messages, just like the old-fashioned e-mail, and I can download information from her memory. It's great to have an e-friend—I am     57     lonely(寂寞的) and I always have someone to talk     58     .

I would like     59     you more about life in the year 3044, but I     60     send my e-friend to clean my room. Maybe one day I will be able to travel back in time and visit you.
