Coffee has been a part of people’s lives for thousands of years, and today it is still a favorite drink of millions of people in the world. Coffee is so popular, but do you know the story of coffee and how it was discovered?

There is an old story that says coffee was discovered in Africa long, long time ago. One day, a farmer was watching his goats, and he saw them eat some small berries(干種子) from a plant.After they ate the berries, the goats became very active. The man often felt tired, so he decided to try the berries too. Surprisingly, he did not feel tired any more. Coffee plants were thus discovered.Then coffee was taken from Africa to Arabia(阿拉伯半島), and there it was first used as medicine. The Arabs kept coffee a secret for many years. Later, coffee came to Turkey, then Italy, then France. From Europe, the coffee plant was taken to America.People found that plants were grown. On these farms, coffee beans were picked from the plants by hand. Then the beans were dried and prepared for market to sell. Different coffee beans were mixed together to produce different kinds of coffee. Coffee was sent to all over the world, and soon became very popular.
