阅读理解 Can you imagine what our life will be like in the year 2050? Perhaps you will be flying off for a holiday on the moon, or maybe you will be taking your dog for a walk in virtual(虚拟的)  reality. We recently carried out a survey of 1 000 people from different countries to find out what they think life will be like in the future. The results clearly show both our hopes and fears. The survey suggests that friendship-one of the most important human relationships-will have changed dramatically(显著地) . People will make friends mainly through the Internet. What is more, a large number of people will come across their future wives or husbands in this way! Computers will have become completely necessary by 2050. Even now, some people begin to regard them as their best friends ! Others, however, say that we will become much more separated and estranged (疏远的)  from each other because we will have little real human contact. Education will have changed a lot, too.  As more and more children will be using computers in schools, certain abilities,  such as mental arithmetic (心算), won't be necessary since there will be computer programs for most calculations(计算). Even writing by hand-at least to some extent-will have become a thing of the past. According to the survey, home life will be more and more comfortable. Most people believe that by 2050 robots will be doing housework and we will rely mainly on ready-made food. A lot of people tlunk that we might only cook for fun in the future. Space exploration will become increasingly popular. Fifty percent of the people we talked to believe that man will regularly visit Mars. They also believe that travel on our own planet will probably change. Almost everyone thinks that there will be no cars in the city center. Some even think that environmentally-friendly electric of solar-powered cars will have replaced the cars we use now. Pollution is something that worries us very much. Some fear that it will continue to get worse, and that it will be impossible for us to live on our polluted planet. Others even foresee that one day we'll have to pay for clean air. On the other hand, people seem to be quite  optimistic about the benefits of genetic engineering, as they think scientists will use it to cure diseases like  cancers and AIDS. If scientists manage to find a cure for these, we'll have a much healthier society. Some people worry about the future, while others  are full of hope and confidence. No matter how dark or bright it may seem, it is up to us to look after our planet and try to make it a better globe to live on. 1. Many people believe that in 2050, we will .
