      Marco Polo was a boy of about seventeen. Once, his father and uncle had just returned to their family
in Venice after a long journey. They talked about strange and beautiful lands in the East. They brought back
gold and jewels.
      Shortly after, the Polo brothers asked him to take a trip with them to the East. So it was how Marco
Polo's journey began. During three years of traveling to the Far East, he saw sights that were almost
unbelievable to a boy from Italy. He met people who had strange ways of living. Some spoke languages
that he did not even understand. At last they reached China. This was in the year 1275. The emperor made
a great feast in honour of (招待) the Polos and asked Marco to live in his court (庭院). Marco Polo learned
to read, write and speak new languages. 
      Once the emperor sent him to distant western and southern part of his empire. Marco Polo was given
many soldiers and servants for his journey. 
      Marco saw paper made by the Chinese. People in China had also discovered how to paint on paper, they
had many books and even used paper money! They burned little black rocks for heat.
      After three years, he wrote a book about his travels, which most people in Europe did not believe. But
many years later the world knew that this man had discovered a great Eastern country.
