問題詳情：

We don’t know how different our future will be in the year 2050. We can only try to imagine it.

At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today—we will feel a little lonely.

Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

Spending holiday will also be completely different. Travelling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.

Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen.
