【正确答案】The Silk Road is an important international trade route between China and the Mediterranean in history.  Since silk accounted for a large proportion of trade along this route, in 1877, it was named the Silk Road by an eminent German geographer. In the meantime, this route served as an artery of exchange for many other products, and more importantly, their technology. One of the most significant objects introduced to China via the Silk Road is Buddhism. Chinese techniques of silkworm breeding, iron smelting and irrigation also spread to Central and Southern Asia and to Europe through the Silk Road.
