The home of the future won’t be completely different and we will be living in houses and flats as we do today. But people will want to shape their homes to match their dreams. No two homes will be the same. People will be able to buy “house materials” containing moveable walls, doors and windows. They will put together the different parts to create the home they want.

Many jobs that we do today will disappear, others will still be done but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t take the place of them. We will still have teachers because students need human contact. But they will be using modern technology in class more and students will be working more from home.

Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then hotels will move around the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centers on the moon with things needed for families.

There will be no paper in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to protect nature. E-newspapers and e-magazines will take the place of traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our re-useable paper.

As we know, the earth is going to disappear sometime in the future. This isn’t going to happen tomorrow but scientists say that it will happen in five billion years. We will have to find another home. At sometime in the future far away, either we stay on the earth and die with it, or we leave and move to another plant. There won’t be any other choice.

The Internet, mobile phones and iPads are parts of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning (克隆) humans.

    We have had lots of technology and it has changed our lives a lot. We are sure that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.

    Global Positioning System (GPS) (全球定位系统)

    It's a system that uses radio signals from satellites to show exact (精确的) information.   It tells you where the user is on the earth in all weather conditions.  It's made up of three parts: satellites, control equipments (设备) on land and receivers.

    Space Technology

    Russian and American scientists have worked together for the International Space Station, (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless (无限的) advantages. It's even hoped that one day space technology will take humans to their new houses in space.

    Underwater Robot

    Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.

    The world is changing so quickly that it's hard for us to catch up with all the new inventions because they seem to come out every month. It's important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modem technology, or we will fall behind the times.

1. _______ can tell you where the user is on the earth exactly.

A. Satellites                                                  B. Receivers

In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to use horses, carriages and bicycles.

In the Second World War, some people didn’t use gas(气体) made from petroleum (石油) in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity to run our cars, but first we must make the electricity! Some countries have coal(煤炭) and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines (涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides(潮). We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.

Which of these ways will be used to run our cars in the future?

1.When might people have to go back to use horses and carriages?

A. When they are poor.

B. When they run out of oil.

C. When they need more exercise.

D. When there aren’t any big trees in the world.

2.What did some people use to make gas in the Second World War?

A. Water             B. Coal                C. Wood and plants D. Tides

3.How many ways are suggested to make electricity in the passage?

A. 2                   B. 5                   C. 4                    D. 3

4.According to the passage, which of the following statements is True?

A. There is more petroleum than we can use now.

B. Trees are needed for some other things besides making gas.

C. We got electricity from ocean tides in the old days.

D. Gas wasn’t used to run cars in the Second World War.

5.The passage is mainly about _________.

A. how to run our cars                     

B. what to do when oil runs out

C. different types of gas                   

D. the ways to make electricity
