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,     1    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     2    body, destroying the cancer cells.

Fighting cancer with nano-robots is only an idea today,     3    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     4    to many of today’s problems.

However, nano-robots could be a     5    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     6    . Scientists will not have the ability to build millions of nano-robots one by one.

This    7    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    8    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    9    nan-orobots or should we search for other methods? This is one of the many difficult     10    that we have to make in the future.
