Did you know that tea, the most popular drink in the world (after water), was invented by accident?
你知道茶——世界上最受欢迎的饮料（继水之后）是偶然间被发明的吗？
Many people believe that tea was first drunk about 5,000 years ago. It is said that a Chinese ruler called Shen Nong was the first to discovered tea as a drink.
许多人相信茶是在近5000年前首次被饮用。据说，有一位叫神农的中国统治者最早发现了茶可以饮用。
One day Shen Nong was boiling drinking water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time.
有一天，神农氏在明火上煮饮用水。一些茶树的叶子掉进了水里，并在水里泡了一段时间。
It produced a nice smell so he tasted the brown water. It was quite delicious and so, one of the world's favorite drinks was invented.
水发出好闻的气味，因此神农尝了尝这褐色的水。味道很不错，就这样，世界上最受欢迎的饮品之一被发明了。
A few thousand years later, Lu Yu, "the saint of tea", mentioned Shen Nong in his book Cha Jing.
几千年后，“茶圣”陆羽在《茶经》这本书中提到了神农。
The book describes how tea plants were grown and used to make tea. It also discusses where the finest tea leaves were produced and what kinds of water were used.
本书描述了茶树是如何生长并被用来制茶的。还讨论了最好的茶叶产自哪里和使用什么样的水。
It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries. In England, tea didn't appear until around 1660, but in less than 100 years, it had become the national drink.
人们普遍认为茶是在六、七世纪被带到韩国和日本的。在英国，直到1660年才出现茶，但是在不到100年里，它已成为国饮。
The tea trade from China to Western countries took place in the 19th century. This helped to spread the popularity of tea and the tea plant to more places around the world.
中国与西方国家的茶叶贸易发生在十九世纪。这有助于传播茶及茶树在世界更多的地方普及。
Even though many people now know about tea culture, the Chinese are without doubt the ones who best understand the nature of tea.
尽管现在许多人知道茶文化，但中国人无疑是最了解茶叶本质的。

Self check
Self check 1 部分Complete the passage with the correct forms of the words in the box.
It is often difficult to decide on the inventor of certain inventions. This is because sometimes a few people may invent things which are nearly the same. It's hard to tell who came up with the idea first. Some inventions can also lead to other inventions all of a sudden. So some people doubt whether the inventor came up with the idea himself or herself. They think that the inventor used someone else's idea to create his or her invention That is why books or websites usually mentionmore than one inventor when giving information about inventions.
通常很难判断具体发明的发明者。这是因为有时候一些人可能发明几乎相同的东西。很难说谁是第一个提出想法的人。有些发明也能突然导致其他的发明。因此一些人怀疑是否是发明者他或她自己提出的想法。他们认为发明者用别人的想法创造了他或她的发明。那就是为什么书本或网站在给出有关发明信息的时候通常提到不止一位发明者。
