     Runners in a relay(接力) race pass a stick in one direction. However, merchants passed silk, gold, fruit,

and glass along the Silk Road in more than one direction. They earned their living by traveling the famous

Silk Road.

     The Silk Road was not a simple trading network. It passed through thousands of citied and towns. It

started from eastern China, across Central Asia and the Middle East, and ended in the Mediterranean Sea. It

was used from about 200 B, C, to about A, D, 1300, when sea travel offered new routes (路线)　, It was

sometimes called the world's longest highway. However, the Silk Road was made up of many routes, not

one smooth path. They passed through what are now 18 countries. The routes crossed mountains and

deserts and had many dangers of hot sun, deep snow and even battles. Only experienced traders could return

safe.

     The Silk Road got its name from its most prized product. Silk could be used like money to pay taxes or

buy goods. But the traders carried more than just silk. Gold, silver, and glass from Europe were much found

in the Middle East and Asia. Horses traded from other areas changed farming practices in China. Indian

merchants traded salt and other valuable goods. Chinese merchants traded paper, which produced an

immediate effect on the West. Apples traveled from central Asia to Rome. The Chinese had learned to graft

(嫁接)　different trees together to make new kinds of fruit. They passed this science on to others, including

the Romans. The Romans used grafting to grow the apple. Trading along the Silk Road led to world-wide

business 2,000 years before the World Wide Web.
