1 Who was Marco Polo?
2 What country did Marco visit when he was 17?
3 How did Marco, his father and uncle feel when they came to
Beijing?
4 What did Marco Polo write about his adventures?
Marco Polo, the famous explorer, was born in Italy in the
thirteenth century. When he was 17 he travelled to China with his
father and uncle. It was a very dangerous journey and they were
very
happy when they came to Beijing. Marco lived in China for 17
years and learned lots of interesting things. He came back to Italy
with lots of beautiful things. He wrote a book about his
adventures. The stories were so amazing that many people
thought they were not true. Now travelling is so easy, we forget
how difficult and dangerous it was long ago.
