Technology is developing fast and it has become an important part of our life. Then what will the world be like in the future?

3-D food will be both delicious and nutritious (有营养的). We can use 3-D printers to print some basic materials. _____ And we can go further. Scientists believe that we just need to turn on a printer in the kitchen and then we can enjoy our favourite food whenever we like.

_____ 5G network will allow many more people to get information. Big companies like China Mobile and China Unicom will start to offer 5G. It is said that 5G promises download speeds 10 to 20 times faster than 4G. For example, we can download a film within just 1 second. But with a 4G network, it takes a few minutes. There will be much bandwidth (带宽) and we can get unlimited (无限的) information.

Underwater cities will provide more space. The earth is becoming more and more crowded. We may turn to underwater homes, which will be built as low as 15 kilometers below the sea. And the different temperatures at the different depths (深度) of the sea can be used to provide power for the homes.

_____ For us common people on the earth, the dream of travelling around space will come true. In the coming years, spacecraft will be as popular as buses, trains and planes. We can leave our home and enter space to take an adventure (冒险). And even we will get used to living there.

A robot will be a part of life. Robots can do many of the same things as we humans do like driving cars. But they will be used in other areas as well. They will be able to think.
