【题目】 The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3，000 years ago. By the time the Chinese silk trade became important in the world, the Silk Road had covered almost 6，500 kilometers. It spreads from Rome to China, which is from the West to the Far East.

Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices(香料), cloth, valuables stones and gold.

There is a famous old story along the old road. It_is_said_that_Roman_soldiers_travelled_through_central_Asia. They started to live somewhere near the ancient Chinese villages of Liqian. Some of these Romans married local Chinese women and the story of blueeyed villages of China started.

During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.

In modern times, the old Silk Road routes(路线) are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35, 000 objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.
