A Cloud of Hope and Danger
In 2050, a small cloud floats through the air in a hospital operating room(手术室). In the room a patient, suffering from cancer, lies on a table. The cloud surrounds (包围) the patient, {#blank#}1{#/blank#}her body and filling her lungs (肺). The cloud is not smoke or steam. It is made of millions of microscopic robots called nano-robots(纳米机器人). These tiny robots move from cell(细胞) to cell in the {#blank#}2{#/blank#}body, destroying the cancer cells.
Fighting cancer with nano-robots is only an idea today, {#blank#}3{#/blank#}scientists say that it would be possible in the future. Using nano-robots for good purposes such as fighting disease or repairing the environment may be the {#blank#}4{#/blank#}to many of today's problems.
However, nano-robots could be a {#blank#}5{#/blank#}risk as well. Since nano-robots are so tiny, they will have to work in large teams of many thousands to 'many millions. For this reason, nano robots will have to be programmed to build {#blank#}6{#/blank#}. Scientists will not have the ability to build millions of nano-robots one by one.
This {#blank#}7{#/blank#}to reproduce(复制)is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nan-orobots would be far {#blank#}8{#/blank#}than any disease. Some people think that if they get out of control, nan-orobots could destroy the Earth.
What should be done? Should we continue{#blank#}9{#/blank#}nan-orobots or should we search for other methods? This is one of the many difficult {#blank#}10{#/blank#}that we have to make in the future.
