Did you know that tea, the most popular drink in the world (after water), was invented by accident? Many people believe that tea was first drunk about5, 000 years ago. It is said that a Chinese ruler {#blank#}1{#/blank#} Shen Nong first discovered tea as a drink. One day Shen Nong was boiling{#blank#}2{#/blank#} water over an open fire. Some {#blank#}3{#/blank#}from a tea plant fell into the water and remained there for some time. It produced a nice smell so he tasted the brown water. It was quite delicious. And so, one of the world's favorite drinks{#blank#}4{#/blank#} invented.
A few thousand years later, Lu Yu, “the saint of tea”, mentioned Shen Nong in his book Cha Jing. The book describes how tea plants were grown and used to make tea. It also discusses where the{#blank#}5{#/blank#} tea leaves were produced and what kinds of water were used.
It is{#blank#}6{#/blank#}that tea was brought to Korea and Japan during the 6th and 7th{#blank#}7{#/blank#}. In England, tea didn't appear until around 1660, but {#blank#}8{#/blank#} than 100 years later, it had become the{#blank#}9{#/blank#} drink. The tea trade from China to Western countries took place in the 19th century. This helped to speed the popularity of tea and the tea plant to more places around the world. Even though many people now know about tea culture, the Chinese are{#blank#}10{#/blank#} doubt the ones who best understand the nature of tea.

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 {#blank#}2{#/blank#} nano-robots (纳米机器人). These tiny robots move from cell (细胞) to cell in the patients' 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. {#blank#}6{#/blank#} this reason, nano robots will have to be programmed to build {#blank#}7{#/blank#}. Scientists will not have the ability to build millions of nano-robots one by one.
This ability 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.
