There was a small village near a mountain. People there loved their village very much and they grew many {#blank#}1{#/blank#} on the mountain. Water in the rivers was very clear and the {#blank#}2{#/blank#} was clean. People lived a poor life, but they were very {#blank#}3{#/blank#} . After a few years, some people in the village started to cut down trees to {#blank#}4{#/blank#} for money. There were some people from cities {#blank#}5{#/blank#} to visit the village. People began to kill some wild animals as {#blank#}6{#/blank#} to treat (招待) the visitors. Of course, they made lots of money. But {#blank#}7{#/blank#} knew what the village would be like in the future. As time went on, there were fewer plants and animals and the water became {#blank#}8{#/blank#}. The visitors became fewer and fewer. Several years later, people there knew they must stop destroying (破坏) {#blank#}9{#/blank#} . They would like to live a happy life as before, so they began to {#blank#}10{#/blank#} new plants. They hoped the village would become as beautiful as before.

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.
