Marco Polo was born in Venice（威尼斯）in 1254. He was the most famous westerner（西方人）to visit Asia during the Middle Ages. He wrote a book about his travels. In his book he wrote all the thing she saw and heard. Many people read the book. But few believed what Marco Polo said. He spoke of strange people and places that nobody knew about at that time.

　　As a young man, Marco Polo decided to travel together with his father. It took them more than three years to travel to China .He became the Chinese Emperor's（皇帝）friend. He learned the Chinese language when he traveled around and talked to many people. Before he reached the age of thirty he was made a Chinese official（官员）. After nearly seventeen years in the east, Marco Polo and his father prepared to return home. When they finally arrived in Venice, their family and friends were surprised to see them again. They had been away for almost twenty-five years.
