You may know that more people drink coffee than tea around  the  world. And that,  after oil, it is the
second biggest traded commodity (商 品).  You may also know that the drink comes from beans which
are first roasted and then ground. But what else do you know about this popular drink?
It is said that the story of coffee started with an Ethiopian goatherd named Kaldi. One day Kaldi was
surprised to see that his goats were behaving very strangely. Instead of grazing(吃草) quietly, they were
jumping around, almost dancing. He also noticed some red  "cherries"  from  a  plant that the goats were
eating. He tried some himself and was surprised by the feeling of extreme happiness and excitement. He
felt like dancing too!
But it wasn't used as a drink at first  it was used as food.  The  coffee  berries,  mixed with animal fat,
were used by monks to stay awake during long hours of prayer. From Ethiopia, coffee was later
cultivated in Yemen and the first hot drink was developed there around AD 1000.  Three centuries later
Muslims were keen coffee drinkers and as Islam spread, so did coffee. Coffee houses appeared in Cairo
and Mecca.
For hundreds of years the plants were protected safely. But some beans were smuggled(偷运)out of
Arabia and taken to India. In the 17th century, coffee was soon grown in a new continent. From India to
Indonesia, a century later the beans were once again smuggled to Brazil.  Brazil is now the largest coffee
producer in the world.
It was the caffeine(咖啡因)that  made  the goats dance and  kept  the  monks awake.  Although it is
found in other soft drinks and tea, coffee  has the most caffeine.  In the short term,  a couple  of cups of
coffee can prevent fatigue and delay sleep. But several  cups  a  day,  every day,  can cause anxiety and
restlessness.
