第4题

Marco Polo was an explorer and merchant whose account (描述) of his travels in Asia was the primary source for the European image of the far East until the late 19th century. Marco’s father,Niccolo, and his uncle Maffeo had traveled to China (1260-1269) as merchants. When they left Venice (威尼斯) to return to china, they were accompanied (陪伴) by 17-year-old Marco.

In 1292, however, he consented and allowed them to sail to Persia (波斯) on a mission, and they were finally able to reach Venice in 1295.Shortly thereafter Marco was captured (俘虏)in a battle and put into prison for a short time. In prison he dictated an account of his experiences to Rustichello, a well-known writer.
