A Cloud of Hope and Danger

    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.

    Fighting cancer with nano-robots is only an idea today, {#blank#}3{#/blank#} scientists say that it could 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 is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nano-robots would be far {#blank#}8{#/blank#} than any disease. Some people think that if they get out of control, nano-robots could destroy the Earth.

    What should be done? Should we continue {#blank#}9{#/blank#} nano-robots 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.
