In the past, technology and progress was very slow. People “invented” farming 12,000 years ago but it took 8,000 years for the idea to go around the world. Then, about 3,500 years ago, people called “potters” used round wheels to turn and make plates. But it took hundreds of years before some clever person thought, if we join two wheels together and make them bigger, we can use them to move things
In the last few centuries, things have begun to move faster. Take a 20th-century invention like the aeroplane, for example. The first acroplane flight on 17 December 1903 only lasted 12 seconds, and the plane only went 37 metres. It can't have been very exciting to watch, but that flight changed the world. Sixteen years later, the first plane flew across the Atlantic, and only fifty years after that, men walked on the moon. Technology is now changing our world faster and faster. So what will the future bring?
One of the first changes will be the materials we use. Scientists have just invented an amazing new material called graphene, and soon we will use it to do lots of things. With graphene batteries in your mobile, it will take a few seconds to charge your phone or download a thousand gigabytes of information! Today, we make most products in factories, but in the future, scientists will invent living materials. Then we won't make things like cars and furniture in factories - we will grow them!
Thirty years ago, people couldn't have imagined social media like Twitter and Facebook. Now we can't llve without them. But this is only the start. Right now, scientists are putting microchips in some disabled people's brains, to help them see, hear and communicate better. In the future, we may all use these technologies. We won't need smartphones to use social media or search the internet because the internet will be in our heads!
More people will go into space in the future, too. Space tourism has already begun, and a hundred years from now, there may be many hotels in space. One day, we may get most of our energy from space too. In 1941, the writer Isaac Asimov wrote about a solar power station in space. People laughed at his idea then, but we should have listened to him. Today, many people are trying to develop a space solar power station. After all, the sun always shines above the clouds!
What does the writer say about space solar power?
A. It's an old idea, but people are only starting to develop it now
B. It's a science fiction idea, and nobody really thinks it will work
C. It's much easier to build a solar power station in space than on Earth
D. People tried it in 1941, but they didn't succeed
The planets and stars are very far away from us. For many years people have wanted to visit space and the moon. People (1) who go into space are called 'astronauts'. The first astronaut went into space about 40 years (2) ago, and some people went to the moon about 8 years (3) ago.
It is dangerous in space. Small pieces of rock (4) pass very quickly all the time. There is no air, so there are no animals or plants.
Astronauts have to take air, water, and food (5) with them. In space, you (6) can't pick up very heavy things easily, but it is difficult to eat and drink. (7) Eating and drinking in space is very strange for astronauts. It isn't good for our bodies to be in space for (8) a long time.
Astronauts don't usually stay there for very long, (9) but some have stayed for a year without any problems. Perhaps in the future we (10) will all visit the moon or have holidays in space.
