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 about 5,000 years ago. It is said that a Chinese ruler named Shen Nong was the first 【小题1】 (discover) tea as a drink. One day Shen Nong was boiling 【小题2】 (drink) water over an open fire.

It was quite delicious, and so, one of the 【小题4】 (world) favorite drinks was invented.

A few 【小题5】 (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 finest tea 【小题6】 (leaf) were produced and what kinds of water were used.
